EFEKTIVITAS BUDIDAYA IKAN LELE DENGAN RECIRCULATING AQUACULTURE SYSTEM (RAS) DI SUJAFISH FARM, KECAMATAN CIKOLE, KOTA SUKABUMI

Amalia Putri Firdausi — 2024-04-01

Catfish was cultivating by The Sujafish Farm, Cikole District, Sukabumi City, in early 2023. Urban cultivation land is increasingly narrow, feed costs are increasingly expensive, and limited water availability hinders freshwater fish cultivation development in Sukabumi City. One solution to get around this is developing Recirculating Aquaculture System (RAS) technology. RAS is a cultivation technology where water can be reused after being filtered mechanically and biologically. The maintenance container uses six round ponds with a diameter of 2 m and is filled with water to e height of 0,8 m. The volume of water in each tub is 2.152 L of water. The seeds measured 8 – 10 cm with a density of 318 individuals/m². The observation parameters were temperature, Ph, DO, ammonia, nitrite, nitrate, and fish growth. The RAS application has been proven to maintain water quality, temperature, Ph, DO, and ammonia. RAS systems growth and survival value are higher than circulation, so that RAS technology can be an alternative environmental friendly cultivation technology solution in urban areas.

Limiting factors are very important for plant growth. The aim of environmental limiting factor research is to examine several limiting factors and identify how significant the role of limiting factors is in plant growth. The way the work is done is to observe 4 variations which will be given different treatment. The method used is an experimental study with quantitative analysis, that is, each existing data is processed in tables and explained. The results of this research show significant differences, namely variation A1 has a height of 6.9 cm and a number of leaves of 7 pieces, variation A2 has a height of 19.8 cm with a number of leaves of 72 pieces, variation A3 has a height of 5.3 cm and a number of leaves of 7 pieces. , and the A4 variation has a height of 9.3 cm and a total of 24 leaves. Of all the variations carried out, it is proven that water, soil, air, temperature, and sunlight play an important role in plant growth. A policy recommendation that can be implemented is the use of screen houses. A screen house is a building made of plastic which functions to protect against pest attacks and supports direct sunlight exposure to plants.

DATA PENELITIAN KEONG MAS DI INDONESIA SEBAGAI DASAR KEBIJAKAN BERBASIS SAINS

Mafrikhul Muttaqin — 2024-04-01

The golden apple snail (GAS), Pomacea canaliculata, is a rice pest in Indonesia. Various research on the GAS can be found in Indonesia and other countries. There is a need to analyze that research data as input to formulate a science-based policy for managing GAS. This research compares the trend of the GAS research in Indonesia and other countries. The data suggested a small number of GAS-related research in Indonesia, focusing more on the snail as feed than developing molluscicide in other countries. Furthermore, there is a need to improve the number and quality of GAS-related research in Indonesia, for instance, using modern experimental methods and analysis. Next, mapping the GAS distribution and gathering local wisdom in GAS management can be a good way to increase social involvement. Lastly, that kind of movement can be a basis for formulating further GAS-related research, policies, and sustainable GAS management.

KEBIJAKAN MENUJU KEMANDIRIAN BERAS, KASUS DI KABUPATEN BANYUMAS JAWA TENGAH

Efforts towards rice self-sufficiency are crucial to reduce dependency on other countries for food, yet this poses a significant challenge. The need for land for development leads to a reduction in agricultural land. Policies to protect existing rice fields and increase rice production are highly strategic in the food system, as creating new agricultural land faces various constraints. Research findings indicate that the Regent Regulation on Spatial Planning of Banyumas District 2011-2031 is not fully capable of preventing the conversion of rice fields. This conversion of rice fields leads to a further decline in domestic rice supply, and rice self-sufficiency in Banyumas District is estimated to only last until 2029. Continuity in the implementation among key variables is the key to achieving the system's goals, namely: 1) the establishment of Regent Regulation on Agricultural Land Use Planning (LP2B), 2) the establishment of incentive schemes for land protection, 3) building a detailed spatial database of rice fields, and 4) developing irrigation water access as a variable that must be prioritized in the initial stage, followed by empowering priority farmer groups in the next stage, and increasing rice crop productivity as the subsequent resilience measure. Key actors driving the system include the Regent along with relevant agencies (Department of Agriculture and Food Security, Regional Development Planning Agency, Department of Public Works in the Irrigation Sector, Department of Housing and Settlement Areas), Regional People's Representative Assembly (DPRD), and the National Land Agency (ATR/BPN).

TEKNOLOGI REKLAMASI LAHAN BEKAS TAMBANG BAUKSIT MENGGUNAKAN SEEDBALL TANAMAN ADAPTIF DAN KOMPOS DIPERKAYA FABA

Aulya Putri — 2024-04-01

Bauxite is one of the most mined minerals in the world and plays an important role as a raw material for aluminum production. The implementation of bauxite downstream policy has an impact on the expansion of bauxite mining area and bauxite post-mining land. The expansion of mining activities can cause an increase in the impact of environmental damage, one of which is the emergence of critical land in post-mining areas. Bauxite post-mining land often experiences problems with soil physical and chemical properties, which cause soil unable to support growth and fulfill plant nutrition needs. Alternatives that can be implemented is the use of adaptive plant seedball and Fly Ash-Bottom Ash (FABA) enriched compost utilization as ameliorant material. Post-mining land reclamation technology is the key to achieve successful reclamation and support the optimization of sustainable bauxite downstream programs in Indonesia.
