Toxic waste content can contaminate water and substrates. The physical form of hard and sharp waste material can hurt marine organisms. This research aims to analyze the characteristics of meso sized marine debris in tourist destinations on west coast of Mataram city. Samples were collected at two stations that representing the tourist destinations on west coast of Mataram City, namely Penghulu Agung Beach and Ampenan Beach. Waste measurement using a 3 transect system measuring 10x10 m which is divided into 10 plots measuring 1x1 m for each station. Waste observed in this research was meso-size marine debris. Each item were identified, then calculated for relative density and density per item based on number and weight. Based on the results of the research, 10 categories of waste were obtained at both stations. This type of waste includes plastic, rubber paper, textiles, wood, metal, glass, ceramics, hazardous and toxic materials (B3), and other waste. Plastic waste dominates at both stations, reaching 68% for Station I and 75% for Station II. The density of waste is higher at Station II with an average of 8.67 items.m-2 compared to Station I with an average of 3.33 items.m-2. At Station I there is an average of 2.27 items.m-2 of plastic waste while in station II, plastic waste is much higher, which is 6.47 items.m-2. The average weight of total meso-sized waste collected from stations I and II is 2.78 g.m-2. Station I has a total waste weight of 0.56 g.m-2 and station II weight 4.99 g.m-2. The highest waste weight is for plastic waste type which is 0.24 g.m-2 at station I and 2.49 g.m-2 at station II.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"12 1-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114113403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kawasan ini terdapat ekosistem mangrove yang menjadi daerah konservasi. Kesuburan ekosistem mangrove sangat didukung oleh adanya unsur hara di perairan. Unsur hara di perairan juga akan mempengaruhi kelimpahan dan distribusi fitoplankton di perairan. Tujuan dari penelitian ini adalah untuk mengetahui kadar nitrat, fosfat, serta kelimpahan dan distribusi fitoplankton yang terdapat di wilayah perairan konservasi mangrove Morosari Demak serta mengetahui hubungan antara kelimpahan fitoplankton dengan kadar nitrat dan fosfat yang ada di perairan. Penelitian ini telah dilaksanakan pada bulan Mei 2018 di wilayah perairan Morosari, Demak. Lokasi pengambilan sampel air dan fitoplankton terdiri dari 6 stasiun. Variabel yang diukur dalam penelitian ini antara lain oksigen terlarut, pH, salinitas, suhu air, nitrat, fosfat, dan kelimpahan fitoplankton. Hasil penelitian menunjukkan bahwa kadar oksigen terlarut berkisar antara 2.18 – 6.11 mgL-1, pH 6.12 – 7.38; salinitas antara 18.43 - 31.84o/oo; suhu air antara 27.18 - 30.43 °C, nitrat 0.0029 – 0.2495 mgL-1; fosfat 0.0013 – 0.11 mgL-1. Kelimpahan fitoplankton yang didapatkan dari penelitian ini berkisar 5,700 – 24,942 selL-1. Jenis fitoplankton yang mendominasi berasal dari genus Guinardia (kelas diatom/Bacillariophyceae) yang ditemukan di semua lokasi penelitian. \u0000 \u0000Kata kunci : Fitoplankton, Kesuburan perairan, Morosari, Pesisir","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134336509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Success in preventing environmental pollution is closely related to the quality of the EIA document, especially the quality of the consistency aspects, such as the consistency between the hypothetical significant impact and the initial environmental baseline, the estimated magnitude of the impact, the environmental management and monitoring plan. Therefore, it is very necessary to assess the consistency of the EIA Document in the Province of South Sumatra. This research aims to assess the consistency test of the EIA Document approved by the EIA Assessment Commission of South Sumatra Province. This study used descriptive qualitative method. The research sample was taken using a total sampling technique, all EIA Documents that have been assessed by the EIA Assessment Commission of South Sumatra Province between 2018-2020 and already have an Environmental Feasibility Decree totaling 12 (twelve) documents are used as research samples.
