Sari, Y. P., Wedari, L. S., Sawestri, S., & Rais, A. H. (2024). Fishing activities in The Kampar River, Buluh Cina Village, Riau. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 523-532). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The Kampar River is one of the important rivers in Riau, where it is the main contributor to the District's Gross Regional Domestic Income (GRDP) Kampar. The status of fish resource utilization in the Kampar River is a major concern. The aimed of this research was to obtain data on capture fisheries activities which include fishing gear type, production and fishing gear rate, also fish catch composition in the waters of the Kampar River, Buluh Cina Village, Riau. The research was conducted from March to October 2022. Fish sampling involved 10 fishers who recorded their catches (enumerators). The total catch value was calculated form the total catch of enumerator fishers in one month. Furthermore, the calculation of capture rate value for each month was obtained from the relationship between fishing effort compared to catch. Catch data was obtained from 11 types of fishing gear. There were three groups of fishing gear, namely the hook and line group (pancing, rawai, dan tajur), the trap/pot trap group (bubu, lukah, pengilar, sempirai, and toban), and the nets/gill nets group (gill nets, trawls, and cast nets). The research results showed that gill nets and sempirai fishing gear can be used throughout the year and have the highest production results. Cast nets type fishing gear has the highest catch rate. A total of 26 species including fish and shrimp were recorded during the research. The catch was dominated by motan fish (Tynnichys polylepis) 27.02%, pawe (Osteochilus kapperil) 22.30%, and snakehead (Channa striata) 11.05%.

Kelbo, R., Timisela, N. R., & Kembauw, E. (2024). Utilization of People's Business Credit (KUR) to increase the income of rice farmers. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 854–864). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The purpose of this study was to analyze the utilization of KUR to increase the income of rice farmers. The research was conducted in Waimital Village, West Seram Regency. The research sample consisted of 51 KUR farmer respondents who were taken through a census. The results of a simple regression analysis of the effect of KUR utilization on income show that KUR utilization has a positive effect on income. The regression coefficient value of 0.754 means that income increases by one percent, then KUR utilization will increase by 0.754 percent. Farmers utilize KUR well, so income increases which has an impact on the KUR installment process. The results of multiple regression analysis show that the Adjusted R Square value of 0.992 means that production (X1), seed costs (X2) and labor wages (X3) can explain the income of rice farmers (Y) by 99.2%, while the remaining 0.8% is explained by other factors outside the model. The F-count value of 1975.498> F-table 2.802 means that X1, X2 and X3 simultaneously affect Y. The results of the partial test show that X1 is positive, meaning that if production increases by 1 percent, income will increase by 1.024 percent. The t-count value of 51.817> t-table 2.012 means that the production variable has a significant effect on the income of rice farmers. The seed cost is negative, meaning that if seed costs increase by 1 percent, income will decrease by 0.040 percent. The t-count value of -2.402> t-table of 2.012 means that the seed cost variable has a significant effect on the income of rice farmers. Labor wages are positive, meaning that if labor wages increase by 1 percent, income will increase by 0.027 percent. The t-count value of 2.603> t-table of 2.012 means that the labor wage variable has a significant effect on the income of rice farmers.

Destri, E., Rejo, A., Hanum, L. (2024). Determination of tempeh wastewater management model in plaju ulu with interpretive structural modeling method. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 409–425). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The development of the household-scale tempeh industry in Plaju Ulu, Palembang, produces wastewater that has the potential to disrupt environmental balance if not managed properly. This research aimed to establish appropriate recommendations for a model of wastewater management for tempeh to minimize the impacts caused by waste disposal. This study uses the Interpretive Structural Modeling (ISM) approach to determine the relationships between elements in formulating the model recommendations. The framework variables for this research include three main elements: the background conditions of education, economy, and socio-cultural aspects of tempeh producers. The research findings indicate that the implementation of wastewater management for tempeh in Plaju Ulu needs to be supported by strengthening formal education through workshops or seminars for tempeh producers on effective waste management techniques, or by collaborating with academics to develop innovative waste processing technologies. The success of waste management also relies on the welfare of tempeh producers, necessitating efforts such as product diversification from wastewater raw materials and providing access to product certification to enhance competitiveness and sales. Additionally, the management of tempeh liquid waste requires the development of local regulations governing the disposal and management of wastewater, involving tempeh associations in discussions to ensure that the management stages are accepted and implemented effectively. A model for managing tempeh wastewater that focuses on education, economy, and socio-cultural aspects is expected to create a sustainable environmental system through good collaboration among all partiesn.
