description: The level of damage to pine trees due to tapping is based on the parameters of the number of taps, width of taps, height of taps and depth of taps. The altitude at which pine trees grow can affect the recovery of pine tapping fields because weather conditions, air temperature and sunlight intensity at each altitude are different. This study aims to determine the condition of pine trees due to tapping, measure the percentage of pine tree tapping field recovery and analyze the effect of altitude on tapping field recovery. The results showed that the average tapping damage at each altitude did not meet the pine resin tapping procedures that had been implemented by Perhutani except for the average tapping height. The height of the place affects the recovery of the tapping field. The highest average percentage of tapping field recovery was found at an altitude of <400 meters above sea level (masl) with a value of 50.40%/tapping and the lowest average percentage of tapping field recovery was found at an altitude of >1,000 masl with a value of 36.05%/tapping.

KONTRIBUSI TANAMAN ENERGI HUTAN RAKYAT TERHADAP PENDAPATAN RUMAH TANGGA PETANI HUTAN DI SEKITAR PLTU ADIPALA KABUPATEN CILACAP
type: item
description: This study aims to analyze the management of energy crops in community forests and their contribution to household income among forest farmers around PLTU Adipala, Cilacap Regency. Using a proportional stratified random sampling method, the study involved 60 respondents from three sub-districts. The results indicate that farmers and their families actively conduct community forest management, starting from land preparation to maintenance using simple tools. Agroforestry systems are applied with alley cropping and enrichment planting patterns, combining timber species (silk tree, teak, mahogany) with non-timber forest products (coconut, Ceylon-olive, clove) and food crops. Marketing is commonly carried out directly from the farmers' land or homes to reduce costs. Income from energy crops contributes 1% to total household income, but with optimized utilization of energy crops and their by-products, such as gamal leaves, this contribution is projected to increase to 25%.hutan rakyat, pendapatan rumah tangga, tanaman energi

ANALISIS PENGHIDUPAN ORANG RIMBA DI KECAMATAN AIR HITAM PASCA PERUBAHAN ZONASI TAMAN NASIONAL BUKIT DUABELAS
type: item
description: In 2019, Bukit Duabelas National Park integrates its zoning system with the Orang Rimba traditional land utilization in attempt to fulfill its mandate to protect Orang Rimba’s livelihood. This research aims to determine wheter the zoning system of Bukit Duabelas National Park has truly accomodated sustainable livelihoods for Orang Rimba by exploring the livelihood resources and livelihood strategies of the Orang Rimba in Air Hitam using mixed methods and the Sustainabe Rural Livelihood framework. The research reveal different capital possession accross nomadic, semi-sedentary, and sedentary groups. Sedentary group possess highest capital across all types, except social. Livelihood strategies have shifted to cultivation (especially oil palm and rubber) with hunting-gathering primarily done by nomadic and semi-sedentary group. Non-agricultural diversification practiced only by semi-sedentary and sedentary group. This change is driven by the need for stable income, declining forest resources, and increased competition. Orang Rimba hold access, withdrawal, and management rights to Bukit Duabelas National Park. Orang Rimba's access mechanism is legal access via social identity, while individual benefits depend more on capital access. To enhance the adaptability of the Orang Rimba, implementing intercropping or optimized weeding is recommended for hunting-gathering communities, while crop diversification or integrated crop-livestock farming is suggested for groups engaged in oil palm cultivation. Furthermore, improving access to education and training is crucial to boost human capital, which is vital for opening up non-agricultural diversification opportunities.

METODE RANDOM FOREST DAN SUPPORT VECTOR MACHINE UNTUK MONITORING PERUBAHAN TUTUPAN LAHAN DI KECAMATAN KLAPANUNGGAL, KABUPATEN BOGOR
type: item
description: Land cover change is an ongoing phenomenon, making regular monitoring essential. One effective approach to land cover classification is supervised machine learning. This study utilizes Sentinel-2 imagery from 2018 and 2024 to monitor changes in land cover. Classification was conducted using two algorithms—Random Forest (RF) and Support Vector Machine (SVM)—in accordance with the Indonesian National Standard (SNI) 7645:2014 for land cover classification. The results indicate that RF achieved a higher accuracy of 92.73%, compared to 90.91% for SVM. Consequently, RF was selected for further analysis of land cover changes. Negative changes totaled 272.42 ha (2.86%), primarily involving the conversion of rice fields into settlements (114.42 ha or 1.2%). Positive changes amounted to 85.6 ha (0.9%), with the most common being the conversion of shrubs into dryland agriculture (43.5 ha or 0.46%).

PERKEMBANGAN PENELITIAN HUTAN RAKYAT DI INDONESIA: TINJAUAN BIBLIOGRAFI
type: item
description: Private forests in Indonesia have an essential role in ensuring communities’ survival. The science of private forest management is necessary for achieving sustainable forest management. However, the science of private forest management is still relatively young compared to the forest management sciences intended to manage large and massive forests. Therefore, it is important to know to what extent the development of the science of private forest management has been through various studies over the years. The objective of this research is to map the development of research in the private forests from year to year, covering the location of research, publications, themes, and sub-themes starting from 2013-2023 as well as to find out the correlation between the theory and practice of private forest management. The research was conducted using bibliographic surveys and analyzed qualitatively descriptively, as well as an annotated bibliography. The research results show that a lot of private forest research is done in West Java Province, with the themes of production and planting sub-themes. Some practices in the field do not apply theory, so private forest management has yet to reach optimum.

ANALISIS KEBIJAKAN REHABILITASI LAHAN MELALUI PEMBANGUNAN HUTAN RAKYAT PADA CABANG DINAS KEHUTANAN WILAYAH I BOGOR
type: item
description: The increasing rate of land degradation in West Java has led to the expansion of critical land areas, which in turn threatens environmental sustainability. One of the strategic efforts to address this issue is through Forest and Land Rehabilitation (FLR) programs, particularly by promoting community-based forest development or "Hutan Rakyat" outside designated forest areas. This study aims to analyze the policy strategies for rehabilitating critical land outside forest areas through community forest development in the jurisdiction of the Forestry Branch Office Region I of West Java Province. The research employs SWOT analysis to identify internal strengths and weaknesses, as well as external opportunities and threats influencing the effectiveness of the policy. Findings reveal various supporting factors, such as government funding, the presence of forest farmer groups, and available guidelines, alongside constraints including unclear land tenure status, limited technological adoption, and insufficient data accuracy. The analysis suggests a combination of strategic approaches, including collaboration with Jakarta's government, engagement of youth, partnerships with academics, and the establishment of legal frameworks to ensure sustainability. These strategies are expected to enhance the effectiveness and efficiency of critical land rehabilitation efforts and contribute to environmental conservation and rural development.

type: item
description: Sungai Buluh Village has 26% forest cover in its Other Land Use Area (APL) which is threatened by land conversion. This threat requires efforts to protect the remaining forest cover by utilizing alternative forest resources in the area. One alternative utilization that can be developed is fruit as a Non-Timber Forest Product (NTFP). For this reason, it is necessary to conduct an analysis of the physical potential and economic value of fruit through field observations, forest inventory, interviews, Focus Group Discussions (FGD) and calculation of economic value. The results show that there are 15 species of fruit, but only 4 species have commercial value, namely durian (Durio sp.), jengkol (Pithecellobium jiringa), keranji (Dialium indum), and longan (Dimocarpus longan L.). Keranji has the highest production potential with 280,746 kg/year, followed by durian with 256,220 fruits/year, jengkol with 58,610 kg/year, and longan with 2,812 kg/year. Durian and jengkol have high resource rent values of Rp 3.751.280/ha/year and Rp 3.351.280/ha/year, respectively. The highest utilization rates are for durian (29%) and jengkol (46%). Sustainable forest resource management and the economic utilization of NTFPs are necessary strategies to enhance community welfare and protect the environment in Sungai Buluh village.

type: item
description: Karyasari Village exhibits low agroforestry productivity, particulary in horticultural crops. A land suitability evaluation is required as a strategy for agricultural development, integrating field data with land suitability classification for horticultural crops. This evaluation employs both matching and scoring methods, yielding four suitability classes (S1, S2, S3, and N). The study’s findings indicate that tree horticultural crops preferred by farmers are avocado, coffee, and cassava. The weighted scores for these crops range between 60-80, with low soil organic-carbon content and steep land slopes identified as limiting factors. This places all community forest land in Karyasari Village whitin the S2 category (moderately suitable).

FAKTOR KONVERSI VOLUME TERHADAP BERAT GAMAL (Gliricidia sepium) BERDASARKAN UMUR TEGAKAN DI SUKABUMI, JAWA BARAT
type: item
description: The conversion factor from stacked wood volume to weight is a widely used method for estimating the biomass of energy plantation forests. However, the general conversion factor for gamal (Gliricidia sepium) established by the Indonesian government does not account for variations in stand age. This study aims to determine age-specific conversion factors for gamal and evaluate the differences in these factors across various stand ages. Field data collection was carried out in a gamal plantation comprising three stand ages—3, 4, and 5 years—located in the Sukabumi Forest Management Unit, West Java. In each stand age, ten gamal trees were felled and grouped based on the similarity in the number of branches to obtain stacked wood samples. A total of 12 stacked wood samples from 30 felled trees were collected across the three stand ages, with their stacked volumes and fresh weights measured to determine conversion factors. The differences in these conversion factors were assessed using the Kruskal-Wallis test. The results indicated conversion factors of 0.286, 0.369, and 0.444 for gamal trees aged 3, 4, and 5 years, respectively. This study confirms that gamal conversion factors differ significantly among stand ages, suggesting the use of age-specific conversion factors would provide accurate estimates of the fresh weight of gamal plantations.

KEBISINGAN DALAM PENYARADAN DENGAN SEPEDA MOTOR (OJEK KAYU)
type: item
description: Modified motorcycles are known as mode for log transportation in remote area. However, these modifications can generate noise. Therefore, it is necessary to understand the noise produced by log transport motorcycles along with its impact on the work environment and workers' health during skidding activities. The purpose of this research is to determine the level of noise exposure and its impact on the surrounding environment and workers' health during log transportation activities. The research was conducted using purposive sampling method with the help of a sound level meter and data analysis in the form of contour maps and Wilcoxon non-parametric tests. The results showed that the average noise intensity received by wooden crossbar taxi drivers during skidding activities ranges from 73.4 dB to 101.5 dB, and the average noise intensity in the surrounding environment ranges from 50.6 dB to 101.0 dB. There are noise intensities exceeding the Threshold Limit Value (TLV) at full throttle conditions for both right and left ears. This condition poses a health risk to workers as noise significantly affects workers' concentration ability, which can be interpreted as: the greater the noise received by workers, the more their concentration ability may decrease.

type: item
description: Chemical properties are a basis for the utilization of biomass based on its components. The chemical properties of wood biomass can differ between species, growth site, age, and parts of the tree. Bark is still considered a by-product of wood utilization, although based on its chemical components, it has the potential for various natural chemical products. Gemor bark has been utilized by forest communities, such as for mosquito repellent. The development of bioproducts based on chemical components is expected to increase the value of gemor bark. For that, it is necessary to understand the chemical components and properties of gemor bark. This study aims to examine the content of chemical components, proximate analysis, and phytochemistry of gemor bark. Gemor bark samples were collected from Central Kalimantan. Determination of chemical component content refers to TAPPI standards (1996), proximate analysis refers to ASTM standards (2013), and phytochemical analysis refers to the Harbone method (1996). The main chemical components of gemor bark consist of holocellulose 63.59%, α-cellulose 46.19%, hemicellulose 17.39%, and lignin 43.56%. The extractive substances dissolved in hot water, cold water, 1% NaOH, and ethanol/benzene are 19.49%, 18.21%, 47.65%, and 27.66%, respectively. Proximate analysis of gemor bark obtained volatile matter content of 78.04%, ash content of 1.32%, and fixed carbon of 20.64%. Qualitative phytochemical analysis detected the presence of flavonoids, phenolics, alkaloids, tannins, saponins, and steroids in gemor bark. Based on its chemical components, gemor bark has the potential as an energy and a source of phenolic chemicals with various chemical properties

MODEL PENDUGA BIOMASSA UNTUK TEGAKAN REHABILITASI DI HUTAN PENDIDIKAN GUNUNG WALAT
type: item
description: Forest rehabilitation plays an important role in increasing forest biomass and carbon stocks. However, there are limited studies that provide information on biomass growth of rehabilitates areas. This study aimed at developing stand biomass growth models for rehabilitated areas in Gunung Walat University Forest. The biomass data of Pinus merkusii stands were obtained by establishing and measuring 115 sample plots in various stand ages by applying the stratified systematic sampling method. The stand biomass growth models were developed by using regression analysis with independent variables consisting of age, diameter, height, basal area, and stand density. The results showed that the stand biomass of Pinus merkusii could be best estimated by stand age (A, year) and basal area (G, m2/ha) using the equation of W = 1,77A0,21G1,12 (R2adj = 99,27% and RMSE = 2,05 ton/ha). When the stand basal area data would not be available, the stand biomass could also be estimated using the equation of W = 0,06A-0,52D2,68 or W = 0,00057A2,37N1,25, which use the stand diameter (D, cm) and stand density (N, trees/ha) in addition to the stand age. These models are useful for the forest manager in estimating and monitoring the stand biomass growth of rehabiltated stands in Gunung Walat University Forest

PENYUSUNAN DAN VALIDASI MODEL ALOMETRIK BIOMASSA POHON EUKALIPTUS HIBRIDA DI UNIT PENGELOLAAN HUTAN TANAMAN DI SUMATRA UTARA
type: item
description: Information on tree biomass potential is closely related to the ability of vegetation to absorb CO2, which is one of the pollutants that can cause the greenhouse effect. Eucalyptus is one of the tree species cultivated in industrial plantation forests in Indonesia, with a relatively short rotation period (3–5 years), and can act as a carbon dioxide absorber. This study aims to develop an allometric model to estimate the total biomass of hybrid eucalyptus trees in a plantation forest management unit in North Sumatra. The sample trees used in this study included 75 trees with diameters ranging from 1.46 to 17.52 cm. The allometric models were developed using CurveExpert Basic 2.2.3 and RStudio 4.4.0, resulting in five selected models: power (M1), exponential (M2), polynomial (M3), rational (M4), and Hoerl (M5). Subsequently, these five models were validated, also involving two others previously existing allometric models at the same site, ultimately resulting in model M1 (W = 0.08378D^2.49572) as the best model. This model, based on this study, demonstrated better accuracy compared to other allometric models for estimating the biomass of hybrid eucalyptus trees at the study site.

PENGGUNAAN STIMULANSIA DALAM PENYADAPAN PINUS KELAS UMUR V DAN VI DI PANINGGARAN, PEKALONGAN TIMUR
type: item
description: The Forest Management Unit (BKPH) Paninggaran, East Pekalongan falls under the pine enterprise-class, where pine resin is the main commodity. Consequently, the productivity of pine resin is highly regarded. The process of resin extraction during tapping is generally aided by stimulants. In practice, BKPH Paninggaran uses both organic and inorganic stimulants. Despite using different stimulants, BKPH Paninggaran has yet to determine which stimulant is the most effective and efficient. This study analyzes the productivity and added value of pine resin tapping when applied stimulants. The research method used a completely randomized design with a two-factor factorial. The first factor is the use of five types of stimulants. The second factor is age class V and VI. The stimulant that resulted in the highest resin productivity was the stimulant with active ingredients of ethylene and citric acid plus 5% sulfuric acid, with an average productivity of 12.98 g/quarre/day, representing a 76.44% increase in resin yield compared to the control (7.36 g/quarre/day). The productivity of pine resin in age classes V and VI did not differ significantly, being 10.13 g/quarre/day and 9.97 g/quarre/day, respectively. There was no interaction between the stimulant factor and the age class. The highest added value of the stimulant was found in the stimulant with active ingredients of ethylene and citric acid plus 5% sulfuric acid, amounting to Rp 52.76/quarre/day.

PRODUKTIVITAS DAN BIAYA PEMANENAN KAYU MANGIUM (Acacia mangium) DI BKPH PARUNG PANJANG KPH BOGOR
type: item
description: The rising demand for wood has outpaced the production capabilities of Perhutani. This study analyzes the productivity and costs associated with forest harvesting. Productivity was measured by calculating the volume of wood and the work time for each stage of the harvesting process: felling (31 cycles), skidding (49 cycles), and transporting (11 cycles). We compared the costs incurred by workers with those incurred by Perhutani. Our findings reveal effective productivity rates of 26.32 m³/day for felling, 21.40 m³/day for skidding, and 19.8 m³/day for transporting. However, the actual productivity for these stages is only 5.54 m³/day. Harvesting in BKPH Parung Panjang operates under a contract system, where low productivity increases total worker costs. The costs incurred per cubic meter by fellers, skidders, and transporters are Rp32,030.55, Rp4,338.04, and Rp67,628.72, respectively. In comparison, the wages they receive are Rp35,000/m³, Rp16,666.67/m³, and Rp70,000/m³. The narrow margin between wages and expenses raises concerns about the welfare of these workers.

STRATEGI BAURAN PEMASARAN PRODUK HASIL AGROFORESTRI PETANI KTH SATRIA MANDIRI CIANJUR, JAWA BARAT
type: item
description: Social Forestry by KTH Satria Mandiri applies an agroforestry pattern, consisting of rasamala, puspa, and non-timber forest products such as coffee, sugar palm, avocado, and cardamom. Like most agroforestry farmers in Indonesia, agroforestry in KTH is not optimal, due to a lack of market access, expertise, and capital. To create good marketing, KTH needs a marketing strategy that can be implemented with the marketing mix concept. This research aims to identify the relationship of the marketing mix to the sales as well as formulate marketing strategies to improve marketing performance. The data was collected through a census of all farmers, using interview and observation. Research data analysis utilizes qualitative descriptive, and SWOT matrix for marketing strategy. The research results show the four marketing mixes applied in the sales process of agroforestry products by farmers at KTH Satria Mandiri. The type of product meets market demand; the selling price is reasonable; it's not necessary for special product distribution and promotion by each farmer. The marketing strategy recommended in the short term is the S-O strategy, and in the long term is the W-O strategy. Increasing production, competitive prices, effective promotions, and a wide marketing network, including the marketplace, can potentially increase product sales.

type: item
description: The formation of social forestry business groups that are evolving within the social forestry program is expected to enhance the business capacity for the well-being of farmers. This research aims to understand the management of social forestry in HKm Solok Radjo and formulate appropriate business development in HKm Solok Radjo. The method used is descriptive statistical analysis with 55 members of HKm Solok Radjo and 16 marketing institutions as respondents. The management of HKm Solok Radjo is carried out on forest products collected from the forest and cultivated plants on the HKm cultivation land. Agroforestry planting patterns are only found in coffee plants combined with Leucaena. The management carried out by farmers includes land preparation, seed procurement, planting, maintenance, harvesting, and marketing. Efficient marketing channels are characterized by shorter marketing chains, lower marketing margins, a higher farmer's share, and an evenly distributed profit-to-cost ratio. Therefore, farmers need to sell their agricultural products directly to consumers and process their products to add value.

KONTRIBUSI HUTAN RAKYAT AGROFORESTRY TERHADAP PENYERAPAN TENAGA KERJA DAN PENGANGGURAN DI PEDESAAN
type: item
description: The Covid 19 pandemic has had an impact on increasing the number of unemployed in Indonesia as a result of restrictions on people's mobility so that many business activities in various sectors have stopped or laid off some of their workers, except for the agricultural sector which has been relatively least affected by these social restrictions. The agroforestry community forest developed by many people in rural areas, even though it is not a labor-intensive activity, is still capable of absorbing labor, either directly from the farming business or through activities that appear as a trickle-down effect of the agroforestry farming business. The study, which was carried out in three locations, namely Burno Village in Lumajang Regency, Karyasari Village and Karcak Village in Bogor Regency, aims to calculate labor absorption from agroforestry community forestry businesses and related businesses from upstream to downstream (wood plant seed suppliers, wood intermediary traders and the sawmill industry) per hectare of forest and analyzing its possible contribution to reducing unemployment. The study results show that agroforestry community forest can absorb labor of 2.28 people per hectare in Burno Village, 2.08 people per hectare in Karcak Village and 1.93 people per hectare in Karyasari Village. With the results of these calculations, if agroforestry development is carried out on half the area (50%) of the abandoned land in Lumajang Regency which reaches around 12,000 ha, it will be possible to reduce the number of open unemployed by around 45%.
