Abstract

Fruit wastes are reported as among the main contributors to the food waste production. They have impact on the environment so they need to be treated. To reduce the negative effects, fruit wastes must be treated before they are released into environment. Meanwhile, the fruit wastes have been reported about their functional properties and nutritional as bio-enzyme. This preliminary study aimed to provide information about the physico-chemical characteristics of bio-enzyme, including pH, dissolved oxygen (DO), total dissolved solids (TDS), color, and smell of bio-enzyme from orange fruit wastes treated different concentrations of probiotic in anaerobic fermentation. Bio-enzyme was a fermented solution made from a mixture of 15 g brown sugar : 5 kg orange fruit waste : 12 L water. We designed treatments of bio-enzyme fermentation with addition of probiotic, namely 0 ml (control), 80 ml (P1), 160 ml (P2), 240 ml (P3), and 320 ml (P4) for each closed plastic drums 25 L in volume and then were fermented for 35 days. The preliminary study resulted that efficiency of brown sugar and effectivity of fruit waste to produced bio-enzyme with pH 3.4-3.6, TDS 982.7-1152.5 ppm, DO 1.4-2.2 ppm, N total 0.017-0.035%, P 0.017-0.02%, K -.046-0.056%, C organic 0.782-0.936%, C/N ratio 28.29-47.36, reduction sugar 0.005-0.134%, total plate number 4.9 x 104 to 1.1 x 105 colony/g, mold & yeast 2.2 x 104 to 5.8 x 104, light brown of liquid color, little sour to sour and freshness in odor, fungi covered surface of the liquid, Si 12.93-22.53%, Al 1.96-2.39%, Ca 3670-6940 ppm, and Fe 214-806 ppm. This research continues for up to 3 months to determine the metagenome diversity of anaerobic microorganism in bio-enzyme fermentation, characteristics of enzyme, reducing sugar production, and chemical properties of bio-enzyme from orange fruit wastes.

Abstract

Kepala timah fish or blue panchax is one of the species found at acidic waters of abandoned ex-tin mining pond. Kepala timah fish belongs to the extremophile fishes which can survive in extreme aquatic environments caused by pressure from environmental factors. This study aimed to confirm the kepala timah fish as a species of Aplocheilus panchax and to analyze its natural food habits. Molecular analysis through DNA barcoding was carried out by analyzing the COI gene and confirming the sequence of kepala timah fish in the gene bank on the NCBI website and constructing a phylogenetic tree for kepala timah fish to other A. panchax populations. Analysis of food habits was carried out by identifying the contents of the digestive tract of kepala timah fish which were observed microscopically. The results showed that kepala timah fish found at acidic waters of abandoned ex-tin mining pond was confirmed as Aplocheilus panchax Hamilton, 1822. Some morphological characters confirmed the similarity between kepala timah fish and A. panchax such as a silvery white spot on its head, terminal type of the mouth position, body shape was sagittiform, small dorsal fin on posterior body, and the shape of the caudal fin was rounded or rhomboid. Analysis of the contents of digestive tract showed the food habits of A. panchax found at acidic waters of ex-tin mining pond was insects. The food habits explained that A. panchax was classified as larvivorous or insectivorous fishes. The presence of A. panchax and its metabolic activity at abandoned ex-tin mining ponds can contributed to increasing organic matter in the waters so that it can be beneficial for improving water quality.

Abstract

Entrepreneurship dapat dijadikan suatu gerakan bersama untuk membangun kemandirian dalam menghasilkan kesejahteraan. Mahasiswa sebagai bagian dari masyarakat akademik dapat menjadi role model sebagai job creator yang diharapkan menginspirasi dan menggerakkan kemandirian masyarakat. Kegiatan pengabdian ini bertujuan untuk memberikan penguatan motivasi kepada mahasiswa sebagai masyarakat akademik untuk membangun inkubator bisnis lobster air tawar (Cherax sp.). Hasil yang diperoleh menunjukkan bahwa Laskar Karapas Biru memiliki komitmen untuk membangun inkubator bisnis lobster air tawar dengan tujuan untuk menghasilkan kebermanfaatan dan produktivitas bagi peningkatan kemandirian dan kesejahteraan masyarakat akademik dan masyarakat pada umumnya. Motivasi warm-glow menjadi kekuatan utama bagi Laskar Karapas Biru untuk membangun unit usahanya. Analisis SWOT menunjukkan bahwa potensi dan peluang usaha budidaya lobster air tawar masih terbuka luas untuk dikembangkan oleh masyarakat. inkubator bisnis lobster air tawar yang digagas oleh mahasiswa Jurusan Akuakultur, Universitas Bangka Belitung diharapkan dapat menginspirasi masyarakat untuk berwirausaha lobster air tawar dengan memanfaatkan teknologi yang sederhana, efektif, dan efisien.

Abstract

Kepala Timah (Aplocheilus panchax, Hamilton 1822) is one of the fish that has the survival abilities to live in a wide variety of quality waters. The ability of A. panchax to survive in acidic waters has begun to be widely studied as extremophile fish to study ecosystems in aquatic habitats that have acidic characteristics. This study aimed to determine the food habits of A. panchax as natural food in acid water of abandoned ex-tin mining activity. The results showed that the natural food for A. panchax was insects larvae or insects that fall on the surface of the waters. The food habits and terminal mouth type confirmed that A. panchax was surface feeder fish, carnivorous fish, larvivorous or insectivorous fish. The sagittiform body type was used A. panchax to did the strategy of feeding behavior by pursue or ambush their prey and it indicated that A. panchax as ambush predator.

Abstract

Aplocheilus panchax (Hamilton, 1822), salah satu spesies ikan yang tersebar luas di berbagai perairan dan ditemukan sebagai spesies endemik di wilayah Oriental. Namun, keberadaan A. panchax di habitat aslinya berpotensi terancam oleh keberadaan spesies invasif, yaitu Gambusia spp. Mini-review ini bertujuan untuk mengelaborasi informasi terkait potensi invasi Gambusia spp. terhadap habitat dan sumber daya yang dimiliki A. panchax sehingga dapat menyebabkan kepunahan A. panchax sebagai endemic species, native species, atau indigenous species di lingkungan aslinya. Hasil mini-review menunjukkan kemampuan hidup dan adaptasi dari Gambusia spp. sebagai spesies invasif atau spesies alien menjadi kekuatan baginya untuk mengkooptasi sumber daya di suatu habitat perairan. Hal ini terlihat pada kemampuan Gambusia spp. dalam beradaptasi melalui sistem pencernaan, pernafasan dan osmoregulasi, serta reproduksi yang sama atau bahkan lebih baik dibandingkan A. panchax. Kemampuan ini dapat membahayakan eksistensi ikan lokal (indigenous species), asli (native spesies), atau endemik (endemic species) yang memiliki sifat seperti Gambusia spp., salah satunya adalah A. panchax. Spesies A. panchax yang selama ini keberadaannya belum mendapatkan perhatian yang dibuktikan dengan status konservasi Least Concern (LC), perlu mendapatkan perhatian lebih di habitat aslinya. Status konservasi tersebut seharusnya perlu direview ulang dikarenakan adanya potensi keterancaman dari ikan invasif seperti Gambusia spp. serta potensi kerusakan ekosistem dan habitatnya. Proses domestikasi perlu dilakukan untuk meningkatkan produksi dan produktivitas A. panchax sehingga dapat meningkatkan populasi dan mendukung upaya konservasi.
