Penelitian ini bertujuan untuk menganalisis kualitas dan korelasi antara sejumlah parameter kualitas perairan di kolong pascatambang timah dengan umur berbeda untuk pengembangan akuakultur. Pengukuran kualitas air dilakukan pada kolong berumur < 1 tahun, umur 20-25 tahun, dan umur > 50 tahun. Hasil penelitian menunjukkan bahwa kolong berumur < 1 tahun bersifat asam (pH 3,71) dengan Eh 0.16 V, DO 5.20 ppm, COD 10.173 ppm, TSS 3.667 ppm, konduktivitas143.75 Us.cm-1, total nitrogen 0.069 ppm, dan total fosfat 0.019 ppm. Karaktersitik perairan kolong berumur > 20 tahun mengalami perbaikan kualitas, khususnya pH dan DO. Hasil pengukuran menunjukkan pH 6.98-7.09, DO 7.07-7.20 ppm, COD 13.900-15.400 ppm, TDS 38.93-81.63 ppm, TSS 6.00 ppm, Eh 0.01-0.02 V, konduktivitas 58.40-122.45 Us.cm-1, total nitrogen 0.021-0.041 ppm, dan total fosfat 0.013-0.021 ppm. Kualitas perairan di kolong pascatambang timah, khususnya di kolong berumur < 1 tahun cenderung berkualitas rendah, meskipun demikian sejumlah ikan ditemukan mampu hidup di kolong tersebut seperti ikan gabus (Channa sp.), sepat rawa (‎Trichogaster sp.), kemuring (Puntius sp.), nila (Oreochromis sp.), tempala (Betta sp.), merak atau cere (Gambusia sp.), seluang (Rasbora sp.), betok (Anabas sp.), selinca (Belontia sp.), berenet atau eyespot rasbora (Brevibora sp.), mata tiga (ikan padi atau javanese ricefish) (Oryzias sp.), dan kepala timah (Aplocheilus sp.). Hal ini menunjukkan bahwa beberapa spesies ikan memiliki kemampuan bertahan hidup dan adaptasi yang baik di lingkungan berkualitas rendah. Sementara itu, ikan-ikan tersebut juga ditemukan di sejumlah kolong yang berumur > 20 tahun. Hal ini menunjukkan bahwa spesies-spesies tersebut memiliki rentang kualitas perairan yang luas untuk kehidupannya serta berpotensi untuk dikembangkan sebagai komoditas akuakultur ataupun organisme suksesor di perairan kolong pascatambang timah.

The challenges faced by the world of education such as universities are not only producing graduates who have good intellectuality, mentality, and morality, but also high productivity and independence. Aquaponics-based aquaculture activities are one of the models that can be developed as a pilot project in the development of productivity and independence of the academic community. This community service activity aimed to present a model in the Program Hilirisasi Produktif (PHP) that can be implemented within the University of Bangka Belitung in particular and the academic community at large. This activity was carried out through an analysis of strength, weaknesses, opportunity, and threat, the stages of preparation of facilities and infrastructure for the application of aquaponics-based aquaculture techniques, the stages of program implementation, and the stages of results evaluation. The activities that have been carried out within a period of three months have produced juvenile of catfish, tilapia fish, broodstock of tilapia, and kangkung vegetables (Ipomea reptans Poir). The sustainability of this activity is very important to make aquaponics-based aquaculture become an effort to produce an independent community in the food sector.

Shipworm is specialized as wood borer bivalve.They has a pair of shell which reduce to a small but highly efficient cutting organ at the extreme anterior end by which they bore the woods up to 19 mm a day. Shipworm derives some nutrition from the wood that they swallow with enzymatic mechanizm and bacterial simbionts. They store their products of digestion in the form of glycogen and fat. Mangrove is their natural habitat, and they also play an important ecological role in the reduction of mangrove woods. Syaputra (2003) has reported that shipworm which lives in Mangrove ecosystem near Tanjung Batu Village is from genus Bactronophorus. It is based on Allan (1962) who said that shipworm with stilt-like pallets, short siphons and the shell with 1.85 cm of length, and total length of pallet reaches 5 cm is Bactronophorus. As the other fisheries coomodities (crabs, shrimps, etc), shipworm could be an alternative source of health food by providing the essential fatty acids. Until now, we still have to catch the shipworm from nature, so that, the yields would be depend on the carrying capacity, catch per unit area, and catch season. For the future, it is important for the stakeholders altogether assuring that our mangrove ecosystem still provides nursery and feeding ground function especially for the shipworm.

Squid (Loligo sp) is one of the most essential fishery commodities and ranks third after fish and shrimp in commercial fisheries. The freshness of the squid is a very important factor and is closely related to its economic value. One of the actors in the marine commodity storage business at Rebo Beach, Bangka Regency uses Cucumbers to maintain the quality of Squid. Until now there has been no scientific research that proves that Cucumber can be used as a preservative for Squid. For this reason, it is necessary to research to examine the effect of using cucumber at different concentrations and soaking times on the organoleptic assessment of squid quality. This research was conducted in February 2020. The handling process for the Squid was carried out at the Squid shelter in Baturusa, Merawang District, Bangka Regency. In contrast, the organoleptic tests were carried out at the Aquaculture Laboratory of the University of Bangka Belitung. The research was conducted by experimental method. The research variables were differences in the concentration of grated Cucumber and differences in the length of soaking Squid. This study used RAL (Completely Randomized Design) Factorial pattern with 2 factors and 3 replications. Treatment factor by giving grated Cucumber and control or using ice cubes at different times and doses. The soaking times in this study were 24 hours and 48 hours with grated cucumber measurements of 50, 100, and 150 grams per 5 liters of water. Data analysis in this study used the Kruskarwalis test. Squid treated with grated cucumber had the same brightness level as ice cubes after 24 hours of soaking. Giving grated Cucumber does not affect the taste and texture of Squid to the level of people's preferences. Giving grated Cucumber as much as 150 g with 24 hours of soaking time can be accepted by consumers and can compete with Squid which is given ice cube treatment.

Fish farming activities carried out by fish farmers often face problems that cause production activities to be not optimal. In fact, increasing production capacity is very important to increase profits. Problems that often arise are basically common. However, due to a lack of mastery of technology and production management, these problems become a major obstacle to optimizing business activities. Fish farmers in Tua Tunu Village, Pangkalpinang City are fish farmers engaged in freshwater fish farming activities, especially catfish (Pangasius pangasius). So far, fish farming activities carried out by fish farmers have faced problems caused by two main factors, namely poor water quality in aquaculture ponds due to waste from feed and fish feces and lack of diversification of fish farming commodities. The purpose of this activity is to provide science and technology applications in the form of technology to minimize aquaculture waste and aquaculture technology systems so that the production capacity of fish farmers increases. This activity was carried out in fish farming ponds owned by fish farmers in Tua Tunu Village, Pangkalpinang City.The specific target is to increase the production capacity of fish farming with the application of technology in all fish farming ponds for fish farmers in Tua Tunu. The method used is a survey method by conducting fish farming activities by inserting technology applications in the form of organic waste trap technology and polyculture system technology. The results obtained show that the production capacity of the pond and the harvest of the fish farmers are more optimal. The results of the activity show that the fish farmer partners can harvest more types of fish and more profits. The water quality in the fish farming media is better. The good water quality from the application of this technology can be seen physically from the color of the water with a lower level of turbidity by suspended solids from feed compared to ponds that do not use this technology.
