The method used in this research is a qualitative descriptive method in comparing land cover changes on each island and also spatial analysis using Google Earth satellite image data in 2013 and 2022. The research results show seven land cover classifications consisting of built-up land, open land, stretches of beach sand, water bodies, plantations, bushes, and mangroves. Based on the analysis of land cover changes in Gili Trawangan, Gili Meno, and Gili Air, a trend of increasing built-up land area for ten years from 2013 to 2022. The most significant increase in built-up land occurred on Gili Trawangan, namely 48.14 Ha. It was followed by Gili Air and Gili Meno, respectively 24.86 ha and 23.71 ha. The driving factor for changes in land cover on Gili Matra is policies from the central, provincial, and regional governments regarding the promotion and establishment of Gili Matra as a tourism destination in NTB Province. Furthermore, this policy impacts the growth of tourists and the number of residents. It causes an increase in the need for tourism-supporting facilities. Therefore, there is a change in land cover, which gradually reduces the area of undeveloped land on Gili Matra.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"106 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139154006","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}

This combination is expected to enhance crop yields, balance nutrient availability, and improve soil structure. The objective of this research was to investigate the impact of the combination of inorganic and bio-organic P fertilizers on soil P availability, P uptake in soybean plants, and the population of Phosphate-Solubilizing Bacteria (PSB) during the vegetative phase. The research utilized an experimental approach with four treatments. Each treatment involved five randomly selected samples, resulting in a total of 20 experimental units. The study was conducted from March to July 2019 in paddy fields in Semoyang Village, Praya Timur Subdistrict, Central Lombok Regency. The treatments used were as follows: P1 (50% of the recommended inorganic fertilizer + 10 g of bio-organic P fertilizer per plant), P2 (75% of the recommended inorganic fertilizer + 10 g of bio-organic P fertilizer per plant), P3 (100% of the recommended inorganic fertilizer), and the control group (without any treatment). The parameters analyzed in this study were the available P content in the soil, soil pH, dry weight of biomass, P uptake in plants, and the population of Phosphate-Solubilizing Bacteria. The results demonstrated that the treatments involving the combination of inorganic and bio-organic P fertilizers showed improvements in all tested parameters compared to using only inorganic fertilizers. The soil pH ranged from 6.56 to 6.64, available soil P ranged from 13.2 to 17.33 ppm, dry weight of biomass ranged from 8.2 to 11.01 grams, P uptake in plants ranged from 10.69 to 16.76 mg per plant, and the population of PSB ranged from 1.14×106 cfu/g to 4.56×107 cfu/g.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"42 174","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139154511","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}
