Abstract

Penelitian ini menilai efektivitas ekstrak daun ubi jalar (I. batatas) sebagai anestesi alami untuk transportasi benih ikan gurami (O. goramy) sebagai ikan uji. Tujuan dari penelitian ini adalah untuk menentukan dosis dan durasi paparan ekstrak yang paling efektif untuk mengurangi stres dan mortalitas pada benih ikan selama proses transportasi. Reaksi fisiologis dan perilaku yang diamati pada benih ikan menunjukkan bahwa ekstrak daun ubi jalar merupakan anestesi alternatif yang aman dan efisien untuk digunakan selama proses transportasi benih ikan. Konsentrasi yang paling efektif adalah 100 ml ekstrak per 8 liter air, dengan waktu pemaparan selama 8 jam, menghasilkan tingkat kelangsungan hidup sebesar 98,50%. Hasil ini menunjukkan potensi penggunaan anestesi alami yang berkelanjutan dan ramah lingkungan di sektor akuakultur, khususnya dalam proses transportasi benih ikan.

Abstract

Nile tilapia (Oreochromis niloticus) is one of the fishery commodities that has developed over time and has a high economic value. The success of aquaculture is closely related to optimal environmental conditions for the survival and growth of the cultivated fish. In a closed system, fish produce waste from metabolic processes that can gradually reach toxic levels. The aim of this study is to reduce the consumption of freshwater and minimize the environmental impact of the waste produced. The research was conducted from May 1 to June 30, 2025, at the Aquaculture Laboratory of the Faculty of Agriculture Indragiri Islamic University. The study employed an experimental method using a completely randomized design consisting of three treatments and three replications. The treatments included using gravel and sand filter materials covered with gauze, using dacron cotton, and not using a filter as a control. Nile tilapia fry were each placed in aquariums measuring 3-4 cm at a density of 15 fish. The parameters analyzed included growth, survival rate, and water quality. The research results indicate that the aquaculture recirculation system provides the best outcomes for the growth and survival of nile tilapia fry. The treatment using gravel and sand resulted in an absolute weight growth of 0.440±0.02 g, an absolute length of 0.95±2.22 cm, and a survival rate of 100±0.00%. The water quality parameters for the treatment using gravel and sand showed favorable conditions with a temperature of 26 ºC, pH of 7.4, dissolved oxygen level of 5.26 ppm, and ammonia concentration of 0.6 ppm. These water quality indicators suggest that the water conditions are normal and support the health of nile tilapia fry.

Abstract

This community service training program aims to enhance students' competencies in using Geographic Information System (GIS) software, specifically ArcGIS, for spatial data mapping and analysis. The significance of GIS in various fields, such as agriculture, environmental management, and urban planning, has grown, making it a valuable skill for students to acquire. The training was conducted in a hands-on format, combining theoretical lectures, practical exercises, and Focus Group Discussions (FGD) to promote active learning and collaboration. The participants, primarily students from the University of Islam Indragiri, were taught to collect geospatial data using Avenza Maps, process the data using ArcGIS, and create basic maps. The results showed a substantial improvement in the participants’ understanding and practical skills, with an average increase in comprehension of 42%. The program was highly appreciated by the participants, who found it beneficial for both their academic studies and future career prospects. In conclusion, the training successfully enhanced students' GIS proficiency, which is crucial for their academic development and employment opportunities, particularly in fields that require geospatial analysis and mapping skills.
