Microplastics (MPs) in landfill leachate are a critical environmental challenge due to their persistence in natural environment, where they resist degradation and pose long-term environmental risks, including harm to aquatic ecosystems and human health. Specifically, Supit Urang Landfill in Malang discharges leachate containing microplastics into the Sumber Beling River, which flows through the densely populated areas of Mulyorejo and Bandulan. This poses a significant risk, as public awareness of microplastic pollution remains low, and residents continue using the river for activities like fishing, washing, and bathing. This study examines the distribution and properties of microplastics in Sumber Beling River and assessed their ecological risk levels. Nine sampling points were chosen to represent pollution sources, upstream quality controls, and downstream sites impacted by pollution. We employed ATR-FTIR spectroscopy for its high accuracy in identifying microplastics, along with an ecological risk assessment using PHI, PLI, and PERI. The results revealed that microplastic abundance varied between 63 and 240 particles / L, with the highest concentration found in densely populated areas (TS.7). The predominant shapes of MPs were films (48.30%) and fragments (42.98%), with polypropylene (PP) and polyethylene (PE) being the most prevalent polymers detected. Although the overall ecological risk was low, site P5, located in the densely populated residential area of Mulyorejo, exhibited a high risk level. These findings underscore the urgent need for targeted interventions in densely populated areas to enhance waste disposal and raise community awareness regarding microplastic pollution.

Urban Growth Dynamics in the New Capital of North Maluku: A Spatiotemporal Perspective on Land Cover Transformation in Sofifi

Mon, 14 Apr 2025 15:09:37 +0700

The transition of North Maluku Province's capital city from Ternate to Sofifi in Halmahera Island is expected to spawn a new growth center. However, the development and expansion of urban areas in Sofifi reflect significant land cover transformation. This process is shaped by complex interactions influenced by the island’s geographical context and limited environmental carrying capacity. To ensure the sustainability of urban growth dynamics in Sofifi, this study aims (1) identify and analyze the spatiotemporal dynamics of land cover transformation from 1995 to 2020 in Sofifi and (2) analyze the growth pattern of urban expansion in Sofifi. This study employed multitemporal Landsat imageries within the 1995 to 2020 period with supervised classification using the CaRT classifier in Google Earth Engine and the NDBI maps to calculate the urban expansion rate and intensity index. The multitemporal analysis shows the rapid transformation of vegetation cover into built-up areas, especially in the 2010–2015 periods, which gradually developed from coastal areas towards inland following the development of road networks and government offices. The spatial expansion index shows the average urban growth in Sofifi from 1995 to 2020 is about 28.61%. This study reveals that the transformation of Sofifi land cover is shifting the vegetation cover to the built-up area by 967 hectares (27.61% of the Sofifi Area) from 1990 to 2020. Parallelly, urban expansion happens in stages. Moreover, this research advances the understanding of how land cover transformation and urban expansion happened in the island cities, particularly in the Indonesian context.

At the local level, social forestry is a key strategy for implementing sustainable forest management that aims to reduce poverty, empower local communities, and improve forest conditions. Granting forest area management permits to local communities requires good business development planning. This study used the business model canvas framework to develop a new business model. The result showed that a new business model was developed by considering the benefits of vegetables, arabica coffee, and tree carbon storage as the value propositions. The customer segments were housewives, restaurant owners, coffee shop owners, and CO2-emitting companies. The products were distributed through trader networks and voluntary carbon market mechanisms. Farmers established direct relationships with trader networks. Revenue streams were derived from the sales of fresh potatoes, carrots, leeks, chilies, coffee beans, and carbon credits. This business model required an area, irrigation equipment, farming equipment, seeds, fertilizers, laborers, and tree biomass measuring tools. Key activities included farming, measurement, and calculation of carbon storage estimates. The partners in this business model were community organisations and local government agencies. The cost structures were investment, operational farming, and costs associated with measuring and calculating carbon storage.

Land tenure conflicts have been a significant problem in Java for decades. The divergence between the state’s legal view and the community’s historical claim to land rights has sparked longstanding debate. This study aims to describe the dynamics of land tenure through empirical evidence of the historical trajectory of land tenure in forest areas in Muara Gembong District, Bekasi Regency. The research was conducted using in-depth interviews, analysis of historical data and literature, and a review of relevant land and forest policy documents. As a result, land tenure policies by the State only gain legal certainty without the legitimacy of local communities. The findings reveal that the land tenure dynamics in Muara Gembong are shaped by a process of state territorialization through the authority of the forestry sector, which is countered by local communities and regional authority efforts at counter-territorialization. This tension has led to tenure insecurity for local communities, as they often lack formal proof of land ownership. The presence of a forest area governance regime that relies on a top-down, command-and-control approach has proven ineffective in achieving its goal of maximizing public welfare. Therefore, future policy directions should focus on inclusive negotiation processes and reforms that ensure tenure security recognized by all parties.

Soil degradation is often indicated by reduced land productivity, which affects soil physical, chemical, and biological properties. The application of compost and biochar fertilizer serves as an alternative method for improving the physical and chemical properties of the soil. This study was conducted to determine the effect of applying compost and biochar to the soil on its physical and chemical properties. The research was conducted in Tambakrejo Village, Sumbermanjing Wetan, South Malang. The study employed a Randomized Complete Block Design (RCBD) with four treatments: control (P0), 15 kg of compost and 5 kg of biochar (P1B3), 10 kg of compost and 10 kg of biochar (P2B2), and 5 kg of compost and 15 kg of biochar (P3B1). The results indicated that the most effective application of compost and biochar in improving bulk density, soil temperature, Corganic, and available P content of the soil was the P3B1 treatment. The composition of compost and biochar P2B2 was found to increase soil pH. Additionally, the composition of P1B3 increased soil moisture, total N, and total K. Based on the results, the application of compost and biochar can reduce soil bulk density, improve soil temperature, pH, and moisture, as well as increase soil Corganic and NPK content.

Mangroves of the Niger Delta in Nigeria have experienced increased degradation due to years of oil exploration/pollution, urbanization, and population explosion. However, studies on mangroves' natural recovery capacity and juvenile requirements are limited. Therefore, this study examined the relationship between natural mangrove regeneration and sediment parameters in the western Niger Delta. The study was conducted in four locations (Agge, Burutu, Opuama, and Kurutie) and a control location in Ifie. Twenty quadrats of 20 × 20 m were laid at each location. Juvenile species composition and density were obtained from sub-quadrats (10 × 10 m). Sediment samples, totaling 100, were taken from 0 to 30 cm depth within each quadrat. The sediment parameter concentrations were determined using standard laboratory procedures. Mangrove juveniles were classified, based on height, into seedlings (< 40 cm), saplings (40–150 cm), and young trees (1.5–3m), with saplings forming a major proportion. Partial least squares regression was used to evaluate the effects of sediment parameters on mangrove juveniles. Calcium, magnesium, sand, organic carbon, electrical conductivity, total acidity, clay, effective cation exchange capacity, salinity, and bulk density were significant predictors of juvenile mangrove species abundance. A high potential for regeneration, particularly for Rhizophora spp. juveniles, has been established. The establishment of mangrove conservation and reforestation projects is therefore recommended.

Microplastic pollution is considered a serious threat because it is associated with potential environmental and human health damage due to its bioaccumulation properties and ecological risks. An initiative emerged to make filters that have technical specifications for quality products. MiniPlast Filter is the newest type of filter innovation, implementing a sustainable system in its use in society. This research aims to determine the working system of the MiniPlast Filter in removing microplastics and the efficiency of eliminating microplastics using the MiniPlast Filter tool. The study examines the effect of using the MiniPlast Filter (independent variable) on reducing microplastics in laundry wastewater (dependent variable). This MiniPlast Filter can reduce the possibility of successfully and effectively spreading microplastics. Based on microscope observations with a dry weight of 7.0 kg, clothes washed by filtering water containing microplastics with the colours of microplastics, namely yellow, purple, red, black, blue and green, were found in observations using a light binocular microscope with a 10x magnification lens at the Botany Laboratory, Halu Oleo University. It was found that the average number of microplastics without using the MiniPlast Filter was 4,710 MPs, and the average number using the MiniPlast Filter was 390 MPs.
