ABSTRAKNelayan di Desa Toniku Kabupaten Halmahera Barat, awalnya menggunakan bagan perahu untuk menangkap ikan teri Stolephorus sp. sebagai umpan perikanan pole and line, akan tetapi pada saat ini banyak tertangkap selain teri yaitu juvenil dan larva ikan, ini permasalahan yang perlu dikaji komposisi tangkapan dari bagan perahu. Tujuan penelitian adalah menganalisis komposisi tangkapan, by-cacth, discard, dan aspek ekonomi. Penelitian dilaksanakan di perairan desa Toniku Kabupaten Halmahera Barat, dari tanggal 1 sampai 9 Juni 2018. Metode penelitian adalah metode survei. Obyek penelitian yaitu ikan hasil tangkapan bagan perahu. Hasil penelitian menunjukkan bahwa tangkapan bagan perahu didominasi oleh ikan target tangkap, yaitu; ikan teri (Stolephorus sp) sebesar 86,295%, tangkapan sampingan 12,335% dan tangkapan yang dibuang 1,370%. Tangkapan sampingan didominasi ikan peperek (Leiognatus sp) yaitu 5,575%. Nilai keuntungan Usaha bagan perahu sebesar Rp 93.047.200,00/tahun dengan B/C ratio 2,96. Berdasarkan perbandingan antara target tangkap dengan by-catch dan discard, bagan perahu di Desa Toniku Kabupaten Halmahera Barat dikategorikan alat tangkap ramah lingkungan dan secara finansial menguntungkan dan layak dikembangkan (berkelanjutan). Walaupun discard rate pada bagan perahu rendah namun usaha-usaha untuk meminimumkan tetap perlu dilakukan. Salah satu usaha yang bisa dilakukan adalah sortir, dan hasil tangkapan yang tidak memiliki nilai ekonomis dibuang ke laut dalam keadaan masih hidup. ABSTRACTFishermen in Toniku Village, West Halmahera Regency, initially used a boat lift net to catch anchovy Stolephorus sp. As bait for pole and line fisheries, but at this time many were caught besides anchovy, namely juvenile and fish larvae, these are problems that need to be studied from the boat lift net. The study objective was to analyze the composition of catchs, by-catch, discard, and economic aspects. The research was carried out in the waters of Toniku village, West Halmahera Regency, from June 1 to 9, 2018. The study method is the survey method. The object of the research is the fish catch by the boat lift net. The study results show the catch of the boat's lift net was dominated by main catch, namely; anchovy (Stolephorus sp) is 86.295%, by-catch 12.335% and discard 1.370%. The bay-catch is dominated by peperek (Leiognatus sp) which is 5.575%. Value of the boat lift net business profit of Rp. 93,047,200.00/year with B/C ratio 2.96. Based on the comparison between catch targets and by-catch and discard, the boat lift net in Toniku Village, West Halmahera Regency is categorized as environmentally friendly and financially profitable and feasible (sustainable) fishing gear. Although the discard rate on the boat chart is low, efforts to minimize it still need to be done. One effort that can be done is sorting, and catches that have no economic value are dumped into the sea while still alive.
Indian scad fish (Decapterus russelli) is a small pelagic fish species commonly caught in Indonesian seas. Excessive fishing efforts can cause population degradation, so it is necessary to understand its population structure. The purpose of this study was to analyze the population structure parameters of Indian scad fish, including growth parameters, cohort, and mortality. Sampling was done by Stratified Random Sampling method. Data analysis used the FISAT II application. Study results showed that there were 4 cohorts. The growth parameters of Indian scad fish obtained asymptote length (L∞) of 296.15 mm, coefficient of growth rate (K) of 0.60 per year, and initial age (t0) of -0.66 years. Value of coefficient of growth rate (K) indicated that growth of scad was relatively slow. The total mortality value (Z) was 0.51 per year, natural mortality (M) was 0.0034 per year, and fishing mortality (F) was 0.51 per year. So that the highest Indian scad fish mortality was caused by fishing mortality. The exploitation rate (E) was 1 per year, indicating that the Indian scad fish resources have been overexploited.
Macro algae is a part of marine plants whose whole body is called the "thallus". Macro algae are widespread in tropical and sub-tropical waters. The purpose of this study was to determine the composition of the macro algae species, the width of the micro-habitat niches, and the overlapping of the micro-habitat niches in the intertidal zone of the waters of Sibu Island, Oba Utara District, Tidore Islands City. The data was collected using survey method using belt transects and squares measuring 1x1 m2 which are placed systematically in zigzags along the tansek belt. In this study, 20 species of macro algae were found in the waters of the island of Sibu, consisting of Halimeda macroloba, Halimeada opuntia forma chordata, Halimeda incrassata, Halimeda opuntia forma renschii, Chaetamorpha sp, Eucheuma cottonii, Sargassum duplicatum, S.polycestum, Turbina ornata, T. conoides, Padina boergesenii, Dictyota dichotoma, Amphiroa fragilissima, Acanthopora spicifera, Eucheuma denticulatum, E. spinosum, Glacilaria salicornia, Hypnea nidulans, Galaxaura apiculata. The results of the analysis of the width of the recesses showed that the macro algae species with the largest recess width were Eucheuma denticulatum with a value of 0.905, while Galaxura apiculata had the narrowest recess widths with a value of 0.200. Furthermore, based on the results of overlapping analysis of microhabitat niches, it shows that the overlap of microbaitate niches is quite large by Sargassum polycestum against Galaxaura apiculata with a value of 0.337, while the lowest was carried out by Halimeda macroloba against Galaxaura apiculata, Halimeda opuntia forma chordata against Galaxaura apiculata with a value of 0.337, while the lowest was carried out by Halimeda macroloba against Galaxaura apiculata, Halimeda opuntia forma chordata against Galaxaura apiculata, Eucheuma spinosum against Galaxaura apiculata with a value of 0.000.
Mangrove forests are biological resources found in coastal areas that have ecological and economic functions. Bruguiera gymnorrhiza is a type of mangrove that grows in the middle and back zones with a muddy sand substrate. The fruit can be used as a local food source, especially in coastal areas that have the potential of mangrove forests, but of course must pay attention to the sustainability of the mangrove ecosystem. This PKM aims to apply the technology of processing the Bruguiera gymnorrhiza mangrove fruit for gulmerda cake and syrup which has a high selling value. The methods used in the Community Partnership Program (PKM) activities are lectures, practice, hedonic testing and mentoring. The results of PKM have increased public knowledge in utilizing raw materials that are around their environment to be processed into products that have a selling value, motivating people to be more independent and confident in developing businesses to improve community welfare, organoleptic testing, Cake gulmerda products are products that have higher score. The formation of the entrepreneurial group "Let's Feel Creative" in the context of the sustainability of training activities.Keywords: Diversification, processed mangrove fruit, gulmerda cake, Dau syrup, North Maitara
Mangrove forest is a natural resource typical of tropical coasts, which has multiple benefits with a very broad impact when viewed from social, economic and ecological aspects. Management of natural resources must be very prudent because it takes a long time to be able to recover when damage / extinction has occurred. The purpose of this study was to determine the composition of mangrove species, the structure of mangrove forest vegetation (species density, relative density of species, frequency of species, relative frequency of species, species cover, relative cover of species and important values) and to determine the level of damage. Extraction of mangrove vegetation using the "spot check" method. The transects are drawn perpendicular to the coastline along the mangrove vegetation. The composition of mangrove species were 7 species, namely Rhizophora apiculata, R. stylosa, Bruguirea gymnorrhiza, Ceriops tagal, Sonneratia alba, Xylocarpus granatum and Aegiceras floridum. In the vegetation structure, the highest density and relative density were found in Rhizophora stylosa and the lowest was Xylocarpus granatum. The highest species and relative frequencies were Rhizophora stylosa, R. apiculata and the lowest were Bruguiera gymnorrhiza. The highest type and closure were Sonneratia alba and the lowest was Ceriops tagal. Meanwhile, the highest importance was in Sonneratia alba and the lowest was Xylocarpus granatum. Overall, the density value of mangrove species on Manomadehe Island is 2796 trees / ha so that the condition of the mangrove forests on Manomadehe Island is still in the good category (very dense).
The health condition of mangrove forests can be determined by assessing forest health indicators. One of the indicators used in determining the health of mangrove forests is faunal biodiversity. Measurement of forest health is a step that can be taken to ensure forest functions and benefits. The study's objectives were to determine the composition of mangrove species and mangrove forest fauna (birds and epifauna), to determine the structure of the fauna community which includes species diversity and species dominance and to determine the health condition of mangrove forests on Moti Island, Ternate Island District. This research was conducted on Moti Island, Moti District, Ternate City, North Maluku Province for six months, April - September 2021. A Sampling of mangroves was carried out using the "spot check" method. Meanwhile, the method used to assess mangroves' health condition refers to the FHM (Forest Health Monitoring) method. There are nine species of mangrove, namely Rhizophora apiculata, Rhizophora stylosa, Rhizophora mucronata, Bruguiera gymnorrhiza, Sonneratia alba, Xylocarpus granatum, Avicennia offincinalis, A. marina and Nypa fruticans. While the composition of fauna species is as many as 18 species consisting of Epifauna (Gastropoda = 12 species, Bivalve = 2 species) and birds as many as four species. The diversity of mangrove forest fauna species in all research locations is moderate and no species dominate. The health status of mangrove forests, both Tafaga and Figur villages, has 60% good condition, 20% moderate and poor conditions.
