Blue carbon is the ability of coastal and marine ecosystems to absorb CO<sub>2</sub> effectively through photosynthesis which is stored in the form of biomass and sediment. The purpose of this research is to analyze carbon storage in the mangrove vegetation of Sungai Nibung Village. The research was conducted from June to August 2022. The research location was in Sungai Nibung Village, Tulang Bawang Regency, Lampung Province. Measurements of mangrove carbon were conducted in mangrove stands, necromass, and litter using the non-destructive sampling method. The results showed that carbon stored in sediments was greater than carbon stored in the mangrove stands, necromass, and litter. The highest carbon stored in sediments was in coarse clay size sediment because coarse clay can store high nutrients.</p> 2023-04-21T14:07:36+07:00 Copyright (c) 2023 Jurnal Teknologi Perikanan dan Kelautan PERSEPSI NELAYAN TERHADAP RUMPON PORTABLE DI PELABUHAN PERIKANAN PANTAI LARANGAN, KABUPATEN TEGAL 2023-09-29T14:32:44+07:00 Roza Yusfiandayani Mohammad Imron Wazir Mawardi Mulyono S.

The most common fishing gear in Karang Jeruk waters are anchovy seine net and mini purse seine. The use of portable FAD technology is expected to create fishing areas and anticipate the occurrence of degradation of fishing areas. The purpose of this activity was to determine fishermen's perceptions of the use of portable FAD innovations in Karang Jeruk waters, Tegal Regency. The research method was carried out using interview methods and experimental fishing activities. Fishermen's perception data was conducted by interview using a questionnaire to 50 fishermen in anchovy seine net and mini purse seine, with accidental sampling of respondents. All fisherman perceptions of portable FADs were grouped into 3 categories, most fishermen have a high level perception of 38 people (76%), a medium level of 11 people (22%), and a low level of only 1 person (2%). The use of portable FADs hads advantages including: high catch productivity, various types of catch, and a large number of fish fit for catching categories.</p> 2023-04-30T10:12:17+07:00 Copyright (c) 2023 Jurnal Teknologi Perikanan dan Kelautan IDENTIFIKASI TUTUPAN DAN KONDISI PERAIRAN PADA EKOSISTEM LAMUN DI PULAU TIDUNG KECIL 2023-09-29T14:32:39+07:00 Ratih Nurmasari Amira Hasna Aulia Putri Sherly Rosmaida Uswah Nurkhalifah Fauzi Ramadhan <p>One of the flowering plants that live underwater and grow in shallow marine waters and estuaries is seagrass. Seagrass ecosystems are very important because they play a supporting role in fisheries and are related to other coastal ecosystems such as coral reefs and mangroves. There are several factors that can affect seagrass growth such as temperature, salinity, depth, and current. This research aimed to identify the cover and water conditions in seagrass ecosystems on Small Tidung Island. The method used in determining the percentage of seagrass cover was the quadrant transect method, namely, drawing a line drawn straight over the seagrass field. The quadrant itself was part of the frame which had the shape of an equilateral rectangle which was then placed on the line. Based on the results of research on the island of Small Tidung Island in 3 stations and 5 plots, showed an overall average seagrass cover of 30.4%, and the quality conditions of temperature, salinity, depth, and current there were good for seagrass growth.</p> 2023-05-05T09:18:29+07:00 Copyright (c) 2023 Jurnal Teknologi Perikanan dan Kelautan KESELAMATAN KERJA PADA BONGKAR MUAT KAPAL MINI PURSE SEINE 10 GT DI PELABUHAN PERIKANAN LEMPASING 2023-09-29T14:32:37+07:00 Lilis Nurbaiti Budhi Hascaryo Iskandar Iin Solihin <p>Lempasing Coastal Fishing Port (PPP) is the largest fishing port in Lampung. One of the most widely operated vessels in Lempasing Port is the mini purse seine. There are various activities at Lempasing fishing Port, namely landing (unloading) and marketing of fish. Loading and unloading activities at the Lempasing Fishing Port are the main activities, after the ship docks at the dock. Accidents that occur in loading and unloading activities can cause losses in the form of delays in activities. The purposes of this research were to identify activities and potential hazards of loading and unloading activities for mini purse seine vessels, analyze the accident rate and risk opportunities that may occur, provide recommendations/alternative solutions, and determine work accident control measures. The survey method descriptive HTA (Hierachy Task Analysis) was used in this research. The results showed that there were 47 accident risks in loading and unloading activities, 36 (77%) moderate risk activities, 5 (11%) two activities (4%) severe risk, and 4 (9%) fatal risk activities. The greatest risk of work accidents occurred in unloading activities. This was because there were around 20 individuals involved, and the activities carried out were quite heavy.</p> 2023-05-07T22:25:14+07:00 Copyright (c) 2023 Jurnal Teknologi Perikanan dan Kelautan TEKNIK MIKROENKAPSULASI PEPTON IKAN MULTISPESIES BUSUK MENGGUNAKAN PERBEDAAN KECEPATAN HOMOGENISASI 2023-09-29T14:32:34+07:00 Tati Nurhayati Bustami Ibrahim Theresia Puspita Arumsari <p>Peptone is hygroscopic so it needs to be protected by microencapsulation technique.

Peel off gel mask is one of beauty cosmetics for facial skin care. The main ingredients of peel off gel mask are antioxidant compounds, namely <em>T. conoides</em> seaweed and <em>M. ole</em><em>i</em><em>fe</em><em>ra</em> L. Moringa leaves. Antioxidant compounds can inhibit free radicals on the skin and are able to treat and rejuvenate facial skin. The purpose of the study is to determine the effect of adding different ratios between <em>T. conoides</em> seaweed and <em>M. oleifera </em>L on the physical and chemical quality of peel off gel masks and to determine the best ratio. This study was an experimental laboratory with one factor. The treatments were used different ratios of <em>T. conoides</em>: <em>M. oleifera </em>L, i.e. R0 (0:0), R1 (1:3), R2 (1:1), and R3 (3:1) with three times test. The results showed that irritation test from 2.6 to 3.8 indicates that it did not cause irritation to the skin; pH value was ranged from 5.28-6.09; viscosity value were 8,193.33-29,416.66 cps; value of drying time were 9-23.33 minutes; antioxidant activity value IC<sub>50</sub> were 9,514.35-99,683.20 mg/L; and hedonic test were 4.73-8.20. It can be concluded that the addition of a different ratio <em>T. conoides</em> and <em>M. oleifera </em>L has an effect on decreasing pH, viscosity value, increasing the value of antioxidant activity of peel off gel mask compounds, irritation value, hedonic, and drying time. The best ratio was in the R1 treatment (<em>T. conoides</em> 5% and <em>M. oleifera </em>L 15%).</p> 2023-06-14T14:32:49+07:00 Copyright (c) 2023 Jurnal Teknologi Perikanan dan Kelautan AKUMULASI LOGAM BERAT TEMBAGA DAN TIMBAL PADA MANGROVE Rhizopora mucronata DI KARANGSONG, INDRAMAYU 2023-09-29T14:32:12+07:00 Agustinus M Samosir Meilita Syarifah Sulistiono Sulistiono <p>Mangrove has many ecological functions, one of them is to absorb, transport and store substances including toxic materials. This research aim is to analyze the concentration of Cu and Pb in root, leave, and substrat of mangrove <em>Rhizopora mucronata</em> and its bioaccumulation level. The concentration of Cu found in sediment exceed standar quality by Reseau National d’Observation (RNO), which means the sediment has been contaminated by Cu. The content of Cu in the rootsand leaves of mangrove is greater than Pb, so does the highest level of bioconcentration factor (BCF) was reached by BCF Pb in root at 1.3116 while BCF Cu in roots at 0.5609. This indicates that the potency of accumulation of roots is much higher than the leaves. The highest Translocation Factor (TF) was attained by Pb which is 0.4075 and the lowest is 0.3341 in Cu. Metal translocation from roots to leaves for essential metals (Cu) is lower than in non-essential metals (Pb), it shows that the mangrove use Cu for metabolic activity and growth. The ability of mangrove in accumulating this metals are still low in category according to concentration factor index.</p> 2023-06-18T20:49:39+07:00 Copyright (c) 2023 Jurnal Teknologi Perikanan dan Kelautan
