- Nutritional Content Analysis of Tofu Waste in Catfish (Pangasionodon
hypophthalmus) Farmer Tangkit Baru Jambi
Authors: Bs Monica Arfiana, Sarwo Edy Wibowo, Wulandari Wulandari, Dyah Muji Rahayu, Yatno Yatno
Pages: 142 - 147
Abstract: One of the factors behind the declining catfish farm in Tangkit Baru, Jambi, is the rising price of commercial feed. A lot of fish farmers stop their cultivation. They make independent feed formulations based on existing sources around them. The lack of knowledge and understanding of feed nutrition causes the feed formulations not necessarily with feed standards (SNI) and feed commercial. Nutritious feed is essential for fish growth. The aim is to compare the nutrition of the tofu waste processed for local fish farmers, "Usaha Mandiri" in Tangkit Baru, with catfish feed standards and commercial. Fish feed produced by local fish farmers consists of 2 (two) types of pellets, it is pellet one consists of tofu waste and salted fish (50%:50%), and pellet two consists of a mixture of tofu waste, rice bran, and salted fish (30%: 20%: 50%). Measurement of feed nutrition includes crude protein (AOAC method, 2011); crude fat (SNI method 01-2891-1992); crude fiber (SNI method 01-2891-1992); ash content (AOAC method, 2005), and water content (AOAC method, 2005). The measurement results showed that the nutritional content in pellet one and pellet two, respectively, included crude protein (27.83%; 16.91%), crude fat (8.25%; 5.21%), crude fiber (5.71%; 5.49%), ash content (14.93%; 16.96%); and water content (29.59%; 26.23%). The nutritional content of pellet 1 was better than pellet 2, except for the ash content. The local pellet was by commercial feed and SNI 7548 (2009); pellet 1 is still feasible as an alternative feed for catfish farms.

- Local Knowledge and Practice of Entomophagy in Datengan Village, Kediri,
East Java, Indonesia

Abstract: Malnutrition is one of the serious problems encountered by Indonesia. This research aimed to identify local knowledge and practice on entomophagy in Datengan Village, Kediri, East Java, Indonesia. The entomophagy data were collected by the qualitative approach. The edible insects in this study were honey bee (i.e., Apis mellifera, A. cerana, and A. dorsata) and flying termites (i.e., Macrotermes gilvus and Odontotermes javanicus). All aspects of the local and scientific name, halal status, harvest period, local value, and how to collect, prepare, cook and serve have been described in this article. According to the Indonesian Council of Religious Scholars, termites are halal or allowed to be consumed (it could otherwise be haram, if people feel disgusted). On the other hand, consuming bees (A. mellifera, A. cerana, and A. dorsata) is haram to eat adult bees. Meanwhile, consuming bees that are still in the form of larvae is halal, but it is to be haram if they are eaten separately with honey or hive. There were five challenges in entomophagy such as disgust, allergy, inferior, halal status, and complicated processing methods.

- Community Based Forest Management Strategies and Projections In KPH XIX
Saka South Oku, South Sumatera
Authors: Enda Kartika Sari, Andy Mulyana, Mirza Antoni, Dessy Adriani
Pages: 129 - 135
Abstract: In accordance with the mandate of the law, forests are part state-controlled and must be managed sustainably, for that the existence of KPH is a necessity for all parties. Forest management is generally realized based on forest governance, management plans, forest rehabilitation, forest protection, and conservation. To improve people's welfare, it is necessary to make optimal use of forest areas to support the preservation of natural resources and overcome global climate change. This research was carried out in KPH Unit XIX Saka, South OKU Regency which is located in the forest group of HL Saka, HPT Saka, and HP Saka, South OKU Regency. Data presentation was carried out descriptively and analyzed using the SWOT method. The results of the study show that KPH as a forest area manager at the site level can guarantee the continuity of forest area functions by implementing sustainable forest management with forest ecological values, based on community welfare. The strategy adopted is the SO Strategy, namely by utilizing and promoting the potential of forest resources, especially non-timber forest product resources (HHBK), and the potential for forest environmental services in the KPH.

- Analysis of the Contribution of TSS, pH, Fe, and Mn Parameters to the
Pollution Load Capacity of Coal Mines in the Oal River, South Sumatra
Authors: Roy Sitorus, Eddy Ibrahim, Satria Jaya Priatna
Pages: 136 - 141
Abstract: The Oal River receives coal wastewater input at several companies. Coal mining in the vicinity of the location adds to the burden of water pollution in the Oal River due to waste water disposal activities. The increase in the concentration of coal waste and the pollution load that enters the Oal River water body will have an impact on the reducing capacity of the pollution load. This study aim to provide information on the condition of the pollution load carrying capacity of the Oal River. Determination of the carrying capacity of water pollution loads at water sources using the mass balance method. The characteristic of the Oal River water with the parameters TSS, pH, Fe and Mn have not yet passed the quality standards for river water and wastewater, both according to PP No. 22 of 2021 and South Sumatra Governor Regulation No. 8 of 2012. The Oal River still has the capacity to accommodate TSS and pH parameters.
