This study aimed to evaluate S. platensis powder dietary supplementation on the growth performance and color quality of polar blue cichlids. This study used a completely randomized design experimental method with four different dietary supplementation doses of S. platensis powder, namely 10 g/kg diet (A), 20 g/kg diet (B), 30 g/kg diet (C), and 0 g/kg diet (K). These treatments were replicated four times. The polar blue cichlids as fish samples had 4.07 ± 0.12 cm and 2.15 ± 0.22 g. Diets (38% protein) were produced by coating the commercial feed with S. platensis powder in appropriate dosage. Feeding was performed until apparent satiation twice a day for 45 days. All parameters, including growth performance (feed intake, weight gain, length gain, specific growth rate, feed conversion ratio, survival rate) and color quality (total grid percentage and total chromatophores), were analyzed using an analysis of variance and the Duncan's multiple range test was applied to obtain the best treatment in growth performance and color quality. The dietary supplementation of S. platensis powder had no significant effect on the growth performance of polar blue cichlids. However, this treatment provides a higher total grid percentage of blue color and total chromatophores in the fish. The best treatment on color quality was found in a 30 g/kg diet dose of S. platensis powder. Therefore, 30 g/kg dose of S. platensis powder is effective to improve the color quality of polar blue cichlids, although providing no significant effect on the growth of the fish.

Water quality standard criteria for shrimp farming, as regulated by the CBIB, are a crucial aspect in intensive farming operations. This research aims to assess the suitability of water quality parameters in intensive cultivation of vaname shrimp (L. vannamei) with CBIB standards (Good Fish Cultivation Methods). The research method uses an ex post facto causal design during one shrimp cultivation cycle, with a focus on the condition of water quality parameters compared with CBIB standards in accordance with Minister of Maritime Affairs and Fisheries Regulation Number 75 of 2016. The research results show that most of the water quality parameters during the cultivation period in accordance with CBIB standards, except for alkalinity and organic matter exceeding the thresholds set by CBIB. Abnormal conditions in these two parameters are caused by unpredictable natural and seasonal factors, as seen in unstable fluctuations in temperature and salinity. However, overall, the cultivation system at the research location still complies with the cultivation quality standards set by CBIB. From this discussion, it can be concluded that the water quality parameters at the research pond location are mostly in accordance with CBIB quality standards, with the exception of alkalinity and organic matter which slightly exceed the limits set by CBIB..

One of the determining factors the success of aquaculture is the provision of fish feed. There are many types of fish feed sold in the market, ranging from natural feed to artificial feed. One type of natural fish feed was Daphnia sp. Growth of Daphnia sp can be maximized by utilizing livestock waste as an additional nutrient. The aim of this community partnership program was to socialize to the public about Daphnia sp natural food and provide training to the community on how to cultivate Daphnia sp. The main target was an aquaculture stakeholder namely Women Farmers Group of Permai Tani which was in Gandusari Village, Bandongan District, Magelang Regency. The stages of this activity include tools and materials preparation, program of socialization to partners, implementation, and evaluation program. The working steps of implementing the activity were preparing the tools and materials needed including Daphnia sp seeds, livestock waste (goat manure, chicken manure and eggs) and catfish cultured wastewater as a culture medium. This activity has been carried out well, socialization and training attended by participants from Women Farmers Group of Permai Tani members. The enthusiasm of the participants was very good. This can be seen from sharing and asking activity about how to cultivate Daphnia sp. The results of this activity can increase the production of Daphnia sp which was used as natural fish feed in Gandusari Village, Bandongan District, Magelang Regency.

Serut Village is one of the villages located in Gunungkidul, with the potential for extensive terraced agricultural land. One commodity that can thrive is the saba banana (Musa paradisiaca forma). Serut Village has a Farmers' Group (POKTAN) spread across 7 hamlets that are not yet integrated. The number of members aged 35 and over is still quite low because it is related to knowledge. This is due to the lack of interest of young people in the world of agriculture, which is considered unpromising, so the youth farmer studio program is a solution. This activity aims to cadre and train young people to become strong and independent millennial farmers, using several methods such as outreach, field schools, and training. The young farmers' studio in Serut Village focuses on developing agricultural technology and producing processed Saba bananas as a superior food product. To plan the implementation and sustainability process of the Ormawa HMPS Physics PPK program, we use methods such as field orientation, focus group discussions, training, mentoring, and evaluation with policymakers. The goal is to increase soft skills.
