Abstrak Telah dibuat kompor biomassa berbahan bakar kayu untuk dimanfaatkan oleh penggiat UKM yangbergerak dibidang pengolahan rumput laut untuk dijadikan berbagai makanan ringan. Kompor dibuat dariplat besi 2 mm dengan dimensi 30 cm x 30 cm x 40 cm sehingga dapat menampung bahan bakar yangbanyak dan tidak mudah habis. Ruang dalam kompor dilapisi dengan beton dari cor semen denganketebalan mencapai 5 cm. Kompor ini menggunakan tambahan teknologi blower dari kipas angin untukmembantu proses nyala api, pembakaran dan arah api. Hasilnya kompor biomassa ini mampu digunakanuntuk memasak dodol mencapai 5 jam.Kata Kunci: Kompor Biomassa; Bahan Bakar Kayu, Plat Besi, Blower. Abstract Wood-based biomass stoves had been made to be used by UKM entrepreneurs engaged in the seaweedprocessing into variety of snacks. The stove was made of 2 mm iron plate with dimensions of 30 cm x 30cm x 40 cm so that it can accommodate a lot of fuel and is not easy to run out. The space in the stove wascoated with concrete from a cement which is up to 5 cm thick. This stove used additional blowertechnology from the fan in order to help the flaming process, combustion and the direction of fire. Theresult is that this biomass stove can be used to cook dodol for up to 5 hours.Keywords: Biomass Stove; Wood Fuel, Iron Plate, Blower.
The Covid-19 pandemic has had a major impact on society, such as job losses, rising staples, and economic hardship. Prices of food needs that continue to increase and are not affordable have resulted in food problems, one of which is protein. One of the high-quality protein is protein from fish. Fish as a fishery commodity that is relatively easy to cultivate on a large industrial scale and household scale for food self-sufficiency is catfish (Clarias sp). The purpose of this activity is to add insight and knowledge of the community about budikdamber for food self-sufficiency. The method of implementing community service activities in Kampung Six is carried out by counseling and training methods on Budikdamber. In this training activity, a bucket with 40 liters of water and 20 catfish seeds was used. Maintenance was carried out for 60 days with ad satiation feeding three times a day. Observations were made on growth, survival and water quality. The results of the activity found that 93% of the community partners had understood about Budikdamber. Budikdamber maintenance by partner communities gets an absolute weight growth value of catfish of 14 g, catfish survival value of 75%, and 1 bunch of kale per bucket. Based on the results of this activity, it is hoped that there will be the provision of special land for Budikdamber as an example for people who want to develop in their respective yards.
The high demand for mud crabs in North Kalimantan causes catch to increase in the wild. If it is not balanced with efforts to increase its aquaculture of mud crab, in the future there will be a decline in population. This study aims to determine the growth and survival rate of mud crab seed (crablet, Scylla serrata) in the application method of different types of trash fish. This research used a completely randomized design with 4 treatments and 3 replications. The Crablet used carapace width average 0.07-0.09 cm and weigh average 0.05-0.07 g with total 150 crablets. The treatments applied by trash fish were (A) Tilapia Fish (Oreochromis mossambicus), (B) Longfin Herrings Fish (Ilisha elongata), (C) Sword Fish (Trichiurus lepturus) and (D) Snails (Telescopium telescopium). The results were The best weight growth of crablet occurs in the treatment of T. lepturus (P>0.05) and the highest of survival rates of crablet were found in treatment T. telescopium (P<0.05) than the other. The trash fish were used turned out to be able survival of crablet mud crab (Scylla serrata).
Teknologi budidaya kepiting soka belum banyak diketahui oleh masyarakat. Hal ini yang menjadi ketertarikan peneliti untuk melakukan kajian tentang budidaya kepiting soka di beberapa lokasi budidaya yang berkembang di Tarakan. Tujuan dari penelitian ini untuk menggali informasi tentang beberapa beberapa teknik budidaya kepiting soka di Pulau Tarakan Kalimantan Utara. Metode Penelitian yang digunakan adalah metode deskriptif dengan menggunakan metode survei, dengan pengumpulan data primer dan data sekunder. Data primer meliputi data yang diperoleh melalui sampling, pengukuran, pengamatan dan wawancara. Data sekunder meliputi data penelitian atau kajian yang dipublikasikan secara umum. Komponen data yang dibutuhkan dalan penenlitian ini terdiri atas beberapa parameter antara lain; Luas lahan yang digunakan, sumber bibit kepiting, cara memilih bibit, Jumlah kebutuhan bibit, dan teknik budidaya kepiting soka serta beberapa parameter kualitas air. Hasil penelitian menunjukkan bahwa budidaya kepiting soka di pulau Tarakan menggunakan dua teknik pemotongan organ (multilasi) pada kepiting yaitu pemotongan kaki jalan saja dan pemotongan kaki jalan dan kaki renang. Hasil budidayanya masih menunjukkan tingginya kematian pada kepiting soka yang disebabkan stress pada bibit.
