The shellfish craft business is not only profitable for business actors, but also provides other benefits, including opening up employment opportunities for the community, increasing community creativity due to growing market demand and maintaining the product as a quality work of art. The output targets are household equipment (tissue boxes), interior accessories (wind chimes, door/window curtains) and souvenirs (key chains, brooches). Implementation methods include counseling, demonstration, training and coaching in the development of shellfish waste as a business opportunity. The training activity was successful because the enthusiasm of the participants was so great in pursuing the art of shellfish craft. Various forms of products and models produced are very varied. The products produced are tissue boxes, wind chimes, door/window curtains, key chains and brooches. The formation of a craft group “Creative Kastil” in the context of the sustainability of training activities.
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.
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
