Abstract

In recent years, many net cages for aquaculture activities, especially for culturing Wallago leeri and Mystus numerus are placed along the Kampar River, especially in the Buluhcina Village. The remain of fish feed, namely rotten chicken flesh have polluted the water. This study aimed to identify the cage culture profile; to analyze the feasibility of the business and the carrying capacity of the environment. This research was conducted in August 2016 – March 2017. There are three observation stations,  Station 1 (before the cage area), Station 2 (the cage area) and Station 3 (after the cage area). Sampling was conducted once. The length of the river is 1.4 Km and 594 single unit net cages are placed along 1,2 Km river. Among the cages, 570 units (96% )are used to the culture of W. leeri,  19 units (3.2%) for M. numerus and the rest, 3 units are for rearing Pangasius sp. and Oreochromis niloticus (1 unit). The carrying capacity of the waters is 496.1 tons/year. The current annual production of W. leeri is 228 tons/year, it is less than the maximum potency.  It is predicted that the culture can be increased by 258.5 ton/year or 646 cages. The recent RCR value is 1.120, indicates that this business is profitable and it could be continued.

Abstract

Household, industrial, office and various other human activities produce waste. Based on the type, waste consists of liquid, solid, gas and B3. Each waste management needs to be carried out sustainable so that it will not damage the environment and human health. This paper aims to find out the effectiveness of plants in aquatic waste management. The method used in this research is literature study in the form of research articles that have been published in related fields. The data found will be analyzed descriptively qualitatively and determine the type of plant that is effective in aquatic waste management and the way plants in degrade hazardous substances that are in the waste. The results of the literature study show that some plants have a special mechanism in reducing hazardous substances contained in waste both actively and passively.

Abstract

Fish farming using KJA media is quite developed in Buluhcina village. The development of KJA cultivation in Buluhcina Village affects the socio-economic aspects of the community. Every economic activity carried out by fish cultivators using KJA media is expected to be profitable and sustainable. The problem in this research is whether the activities that have been carried out so far actually generate benefits for cultivators and the business being carried out is feasible to develop. For this reason, this research needs to be done to see how the financing and economic patterns of aquaculture with KJA media. By using the quantitative descriptive analysis method, the conclusions are obtained, namely: The investment requirement for fish farming using KJA media is IDR 9,025,000 with the largest amount of investment being for timber procurement of IDR 5,675,000; The financing pattern for fish farming using KJA media shows a total financing of IDR 21,027,500, where the largest cost incurred is the cost of providing feed of IDR 7,425,000; Net income or profit obtained from fish farming using KJA media is IDR 23,522,500; The R / C ratio value is 2.11 which indicates that the fish farming business using KJA media is included in the business category that is feasible to be developed. The R / C ratio value of 2.11 means that every Rp. 1, - that is issued will get an income of Rp. 2.11, - The payback period value or the value of the ability to return investment from fish farming with KJA media is 0.38 which indicates that the cultivation business fish using KJA media are able to return the amount of investment invested in a period of 0.38 years or ± 4 months only. The ROI value or the return on business ratio is 2.60, which means that every investment of Rp. 1, - will provide a profit or profit of Rp. 2.60,-

Abstract

This study discusses the isolation and identification of disease-causing fungi in the seeds of Tilapia (Oreochromis niloticus) and Catfish (Clarias gariepinus) cultivated in the cultivation pond of Baru Ladang Bambu Village, Medan Tuntung District, North Sumatra. Sampling was carried out as much as 15 fish each. There are four types of fungi that attack tilapia and catfish. The attack rate with the highest species diversity was found in catfish with 4 types of fungi including Aspergillus flavus, Penicillium glabrum, Saprolegnia sp., and Aspergillus niger. Whereas in Tilapia the types of fungi that attack only consist of 2 types, namely Aspergillus flavus and Saprolegnia sp.

Abstract

Ikan tambakan (Helestoma sp.) merupakan ikan air tawar yang bernilai penting. Belum adanya penelitian terkait pola pertumbuhan dan faktor kondisi ikan tambakan (Helestoma sp.) di Danau Panjang. Pengambilan sampel dilaksanakan pada bulan Oktober 2022 dengan menggunakan alat tangkap berupa jaring, pancing, dan perangkap di Danau Panjang Desa Lubuk Siam, Riau. Data dianalisis menggunakan aplikasi Ms. Excel dari hasil analisis pola pertumbuhan ikan (n=32) menunjukan nilai a = 0,0079 dan nilai b = 3,3778, R2 sebesar 0,9554. Pola pertumbuhan ikan tambakan di Danau Panjang bersifat alometrik positif. Faktor kondisi ikan tambakan relatif baik dengan nilai berkisar 0,769 hingga 1,192.

Abstract

In Indonesia, the study of biomarkers is still very few because not many biomarkers are understood in various inland public waters here. The research location was at the Koto Panjang Reservoir as the experimental location and the Sei Tiban Fish Seed Center as the control location. The fish tested were carp and tilapia. Sample analysis was carried out in a certified laboratory at Construction Materials Laboratory, Department of Public Works, and Genetics Laboratory, Universitas Riau. The biomarkers studied were LSI, GSI and MT, and heavy metals observed were Cd, Pb and Hg. The research method was Experimental Design. Based on the statistical test, there was no difference in the LSI value of tilapia in the treatment group and tilapia in the control group (p = 0.187; p > 0.05), while it was different from goldfish (p = 0.0000; p < 0.001). In GSI, both of tilapia and carp showed significant differences (p = 0.0010; p < 0.010) and (p = 0.0060; p < 0.010). The tilapia and carp-treated livers showed the presence of MT while not in the control fish. This indicates that MT can be used as a biological marker of heavy metal exposure compared to GSI and LSI.
