Dr. Wahidin street is an economic pathway for education, offices, and trade. At certain times, the traffic flow is very congested because the road is also the direction to West Lombok district. Based on observations at the research location, it was found that the distance between the Rembiga intersection and the TNI AU intersection was 322.8 meters which caused the movement of traffic flow to be less than optimal between the intersection distances so that it would affect performance at TNI AU intersection. For this reason, the purpose of this study was to examine the performance of the unsignalized intersection at the TNI AU Rembiga intersection due to the continued flow from the Rembiga intersection which is a signalized intersection due to a one-way system engineering carried out on the Dr. Wahidin street and before the implementation of the one-way system on the Dr. Wahidin street. This research was conducted with reference to the MKJI 1997, in which researchers conducted field observations, then collected primary data and secondary data. There is traffic flow engineering on Dr. Wahidin street, by creating a one-way system, had an impact on changing the performance of the unsignalized intersection at the TNI AU intersection to a level of service F with obstructed flow conditions, low speed whereas, before the implementation of the one-way system the level of service was E with stable flow conditions, stalled vehicles.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130048114","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}

The high level of vulnerability of mangrove ecosystems has implications for the importance of quality planning. This study aims to identify the spatial distribution and density of mangrove forests in Gili Lawang using Landsat 9 OLI-2/TIRS-2 satellite imagery. Data processing is done with the help of the QGIS 3.30 application. Data processing consists of band combinations, image classification with the SVM algorithm, classification results accuracy test, NDVI value extract, and reclass NDVI. The results showed that the use of band 564 in Landsat 9 imagery visually resulted in an increase in sharpness in identifying mangrove ecosystems. Classification of objects with the SVM algorithm has overall accuracy and kappa accuracy > 80%. The identified area of Gili Lawang is 432.72 ha, consisting of 37.89 ha of mangroves, 58.11 ha of non-mangrove and 3.75 ha of water bodies. NDVI values at the study sites ranged from 0.068 to 0.87. The maximum NDVI value is found in mangrove objects, while the minimum NDVI value is found in water body objects. Mangrove density in Gili Lawang is dominated by high and very high density. The use of Landsat 9 OLI-2/TIRS-2 imagery in the future is expected to provide positive benefits in providing data and information related to natural resources.\u0000 ","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129227975","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}

The reserve of asbuton is approximately 179.1 million tons with a hypothetical resource of oil amounting to 10,577,646,000 liters. Asbuton is potentially used as an alternative raw material for non-conventional oil. Non-conventional oil from asbuton could be used as a substitute to the depleted resources of conventional oil in Indonesia. Asbuton non-conventional oil could be prepared by extracted bitumen, a heavy hydrocarbon material in asbuton tar sand from its mineral. The bitumen then could be further processed to produce non-conventional oil. Various studies have been carried out to extract bitumen with various solvents. This study uses direct extraction and soxhlet extraction methods with n-hexane solvent to obtain the most optimum percentage of bitumen. Direct extraction method is done by varying the temperature (40, 45, 50, 55, 60oC) and the weight ratio of asphalt and n-hexane solvent (1:20; 1: 30; 1:40; 1:50). Based on the results of research that has been done, the highest percentage of bitumen yield is formed at 40oC and at a ratio of 1:20 that is 88.60% for the direct extraction method. The 1:40 ratio of soxhlet solvent extraction has the highest bitumen yield of 90.97%.
