“…This means that the main priority that needs to be upheld in the management of Lake Sentani pollution is to use government authority in the environmental field to control environmental pollution and damage. The results of this study are in line with the opinion of Asnil (2013) which states that government agencies involved in the utilization of natural resources are the central government, regional governments and the Lake Management Agency. The lake management agency in question is the Office of Environment and Cleanliness, while the Central Government in question is the Ministry of Environment and Forestry.…”

Most of the pollution levels of Lake Sentani waters in the Expo watershed (92%) have been mildly and moderately polluted, while only a small proportion (8%) still meet quality standards. The condition of the level of heavy pollution will be dangerous for the life of living things, especially fish and have an impact on humans. This study aims to analyze the priorities of the Sentani Lake pollution management policy in the strength-opportunity (SO), strength-threat (ST), weakness-opportunity (WO), and weakness-threat (WT) strategies with the A'WOT method. The results showed that the policy priorities that first needed to be implemented immediately in the SO strategy were to Improve Enforcement of Environmental Law with an eigen value of 0.196. The priority of the policy strategy that first needs to be immediately implemented in the WO strategy is to make regional regulations by utilizing Government and community support with an eigen value of 0.267. The first policy priority that needs to be immediately implemented in the ST strategy is to use government authority in the environment to control environmental pollution and damage with an eigenvalue of 0.494. The first policy priority needs to be immediately implemented in the WT strategy is to improve environmental law enforcement so that lake water is not polluted with an eigen value of 0.202.

Penelitian tentang keanekaragaman chlorophyceae pada lambung ikan Asang (Ostechillus hasselti Valenciences 1842) di Danau Singkarak Kabupaten Agam Provinsi Sumatera Barat dilaksanakan pada bulan Juli sampai September 2021 di Danau Singkarak, Sumatera Barat. Metode yang dilakukan berupa studi lapangan dengan penentuan stasiun secara purposive sampling sebanyak 4 stasiun yaitu Sumpur, Batang Ombilin, Sumani dan Panginggahan. Penelitian ini bertujuan untuk mengetahui keanekaragaman Chloropyceae (Ostechillus hasselti Valenciences 1842) pada lambung ikan Asang di Danau Singkarak Kabupaten Agam Provinsi Sumatera Barat. Berdasarkan hasil penelitian ditemukan 6 famili, 4 ordo dan 7 genus Chlorophyceae yaitu Oedogonium, Desmidium, Staurastrum, Cladophora, Scenedemus, Spyrogyra, Cylindrocapsa. Berdasarkan indeks keanekaragaman Chlorophyceae pada lambung ikan Asang pada satsiun 1 dan 2 termasuk kategori keanekaragaman sedang dan pada stasiun 3 dan 4 termasuk kategori keanekaragaman rendah.

Maninjau Lake is located in Tanjung Raya Subdistrict, Agam Regency, West Sumatra Province, with the surface area 9,737.50 ha. Maninjau Lake has one major outlet through the Batang Antokan river flows to the west coast of Sumatra Island. The excessive number of floating net cages, those are upper of carrying capacity, is the biggest problem in Maninjau Lake. Mass fish kills happened frequently due to deterioration of water quality in this lake. This study is aimed to observe the current fishery activities and environmental conditions in Maninjau Lake. The data were collected by survey using interview methods and record statistic data from the government. The results showed that Maninjau Lake has three functions as ecologies, social and economic. The capture fisheries are still using the traditional fishing gears, while the fish culture is using the floating net cages. There were 18 species inhabited in Maninjau Lake, consists of native and introduced species. Moreover, invasive species have been found, namely Pterygolichtys pardalis (Amazon sailfin catfish) and Amphilophus trimaculatus (flowerhorn). Nowadays, it is difficult to catch the native fish, Tor sp (gariang), and the endemic fish, Psilopsis sp (rinuak). Maninjau Lake is in the eutrophic state with quite good waters conditions, but it could become worse since the lake is steadily changing naturally and also anthropogenic activity. The fisheries management in Maninjau Lake should involve the stakeholder groups that have a different degree of interest, the role of management, and related institutions.
