“…The point or area that undergoes the accretion process occurs at the mouth of the Progo River based on the results of the extraction of the coastline in 2018 and 2023, there are changes that show the widening of the river lips and based on field data, accretion occurs due to the rate of sedimentation formed following the river current and forming deposits that jut towards the river in Figure 12 The river carries sediment that starts from the mainland and settles in the estuary area which causes the advancement of the position of the coastline towards the sea [21]. This indicates that the presence of aerial photography technology can be utilized to map environmental characteristics [22], specifically the dynamics occurring along the coastline of Galur District.…”

Monitoring shoreline change is one of the efforts in the management and protection of the coastal environment. Through digital image processing as the utilization of shoreline extraction index can be used as a reference in measuring the rate of shoreline change. Galur District is one of the sub-districts in Kulon Progo Regency that experiences the highest abrasion process, the worst abrasion that has occurred in recent years is located at Trisik Beach where abrasion threatens the existence of stalls, turtle conservation sites and also coastal vegetation that grows along the beach. The purpose of this study is to determine changes in the coastline starting in 2013, 2018, and 2023 and also to analyze numerically through DSAS the rate of change in the coastline both the influence of abrasion and accretion processes in Galur District. The method used in this research is Quantitative Descriptive assisted by Landsat 8 image transformation using Automated Water Extraction Index (AWEI) and measuring the rate of shoreline change using DSAS based on EPR and NSM values. The results of this study show that Banaran Village has the highest shoreline retreat changes where in 2013 - 2018 the shoreline retreat reached 70 meters and in 2018 - 2023 the coastal retreat reached -75.7 meters, while for the rate of change in Karang Sewu Village in 2013 - 2018 the shoreline retreat reached -33.2 meters and in 2018 - 2023 showed the highest abrasion of -33.5 meters.

“…Land use plays a crucial role in determining surface roughness, which, in turn, affects the rate of tsunami inundation spread. The expression of roughness involves coefficient values [28]. Based of Table 4 reveals that water possesses the smallest coefficient value, standing at 0.025, while developed land exhibits the highest coefficient, reaching 0.115.…”

The southern coastal area of Java Island is a subduction area confluence of the Eurasian Plate and the Indo-Australian Plate. The southern area of Temon District, Kulon Progo Regency includes the Central Java-East Java megathrust area. Megathrust Central Java-East Java has a maximum earthquake potential of 8.9 Mw which has the potential to cause a tsunami disaster. The built-up land area in Temon District has a potential threat from the danger of tsunami inundation. The purpose of this study is to (1) analyze the danger of tsunami inundation in Temon District and (2) determine the area of built-up land affected by tsunami inundation. The method used in this study is descriptive quantitative-qualitative. TUNAMI-N3 was used in numerical modelling to determine tsunami inundation hazards and Google Earth Engine was used in analyze built-up land in Temon District. The results of tsunami inundation hazard treatment and built-up land areas were analyze using ArcGIS 10.8 to determine built-up land affected by the potential tsunami inundation hazard. The results showed that the tsunami generated from the earthquake scenario with a magnitude of Mw 8.9 had a maximum height of 19.86 meters with an average travel time of 33 minutes to reach the coastal area of Temon District. Temon District affected by tsunami inundation hazard has a tsunami area of 2.47 km2 with details of a low tsunami danger level of 0.67 km2, medium tsunami danger of 0.95 km2 and high tsunami danger of 0.85 km2. The maximum height of the tsunami inundation bath is 6.54 meters. Temon District has a built-up land area of 14.308 km2. Built-up land affected by tsunami inundation is 0.55 km2 with details of 0.14 km2 at low danger of tsunami inundation, 0.20 km2 at medium danger of tsunami inundation and 0.21 km2 at high tsunami inundation hazard.

Penelitian ini bertujuan untuk mengetahui kadar emisi gas buang dan pengaruh variasi ukuran celah katup dengan bahan bakar biodiesel (B35) terhadap emisi gas buang pada mesin diesel tipe FE71PS 3908 cc. Penelitian ini merujuk pada regulasi pemerintah tentang baku mutu emisi gas buang kendaraan bermotor tipe baru kategori M, N, O. Alat yang digunakan untuk mengukur kadar emisi gas buang adalah smokemeter, proses penelitian ini dilakukan dengan variasi ukuran celah katup masuk 0,30 mm, 0,35 mm, 0,40 mm, 0,45 mm, dan celah katup buang 0,30 mm, 0,35 mm, 0,40 mm, 0,45 mm, dengan akselerasi mesin 2000 rpm, 2500 rpm, 3000 rpm. Pengujian dilakukan sebanyak 16 kali variasi celah dengan katup bahan bakar biodiesel (B35) murni yang didapat dari SPBU terdekat, diharapkan hasil pengujian ini mendekati program pemerintah Indonesia menuju EURO 4 untuk memperoleh kadar emisi gas buang yang sangat rendah serta ramah lingkungan. Berdasarkan hasil pengujian dan analisis data yang telah diperoleh, maka dalam penelitian ini dapat diambil kesimpulan pada ukuran katup masuk 0,40 mm dan katup buang 0,40 mm dengan mesin 2000 rpm yang menghasilkan opasitas sebesar 0,6 %. Untuk ukuran katup masuk 0,40 mm dan celah katup buang 0,40 mm dengan kondisi mesin di rpm 2500 yang menghasilkan opasitas sebesar 1,3 %. Begitupula untuk ukuran katup masuk 0,40 mm dan katup buang 0,30 mm serta ukuran katup masuk 0,40 mm katup buang 0,45 mm dengan rpm 3000 mempunyai kesamaan yang menghasilkan opasitas sebesar 2,6 %.
