Abstract

Pipelines play an important role in operations in energy supply companies, whether geothermal, gas, or petroleum. Pipeline damage, such as corrosion, dents, and leaks caused by natural or human factors, must be detected. Problems with pipeline assets will indirectly impact high production prices. Pipeline asset mapping must be carried out precisely, quickly, and quietly, considering that the existence of pipelines often causes social unrest. This research analyzed the capabilities of UAV LiDAR for mapping pipelines and support in a three km-long pipeline area. The study concluded that UAV LiDAR can map the position of the pipeline, its position to the ground, the position of the support, and the height of the support on a pipeline network with a diameter of 1 m. This capability applies not only to segments in open areas but also to those covered by vegetation. When orthophoto cannot display the pipeline's existence, the LiDAR point cloud can identify it. This main pipeline, which has a 1 m diameter, 3-D mesh, and 3-D models, can also be formed well. The accuracy of the resulting map is 11.5 cm at a confidence level of 90%. The length of time required from preparation to the presentation of the pipeline longitudinal profile map is eight calendar days with ten manpower.

Abstract

Terrestrial water storage (TWS) anomaly has been a robust indicator in predicting and monitoring hydrometeorological hazards and sustainable water resources management to comprehend the water dynamics on Earth. The Gravity Recovery and Climate Experiment (GRACE) satellite identifies this change by heeding the Earth’s mass anomalies since 2002. However, due to an 11-month data gap before the operation of GRACE-FO, continuous investigation using GRACE has been challenging. This study employed an extreme gradient boosting (XGBoost) algorithm to reconstruct GRACE TWS anomaly by integrating the hydroclimatic variables from Noah surface models over a span of approximately 20 years, focusing on five Kalimantan basins. The testing set was evaluated using three statistical metrics, resulting in a correlation coefficient (CC) of 0.943, Nash–Sutcliffe efficiency (NSE) of 0.887, and scaled root-mean-square error (RMSE*) of 0.337. This approach effectively addresses the research gap in utilizing the GRACE product in an archipelago state such as Indonesia and offers an efficient method for reconstructing TWS anomalies for various hydrological systems at the local scale.

Abstract

Abstrak: Timbulan sampah Kecamatan Gunung Anyar Kota Surabaya mengalami peningkatan walaupun telah memiliki berbagai fasilitas pengelolaan sampah seperti TPS3R. TPS3R Gunung Anyar direncanakan mengelola sampah sebesar 1.161 ton/tahun, namun saat ini hanya mampu mengelola sampah sebesar 595 ton/tahun dengan residu 48,7%, melebihi batas yang seharusnya mampu dihasilkan oleh TPS3R sebesar 30%. Penelitian ini menganalisis kondisi pengelolaan sampah di TPS3R Gunung Anyar dan optimalisasi kinerjanya untuk mencapai target pengurangan sampah pemerintah. Metode yang digunakan pada perhitungan timbulan dan komposisi sampah mengacu pada SNI 19-3964-1994 dengan menggunakan metode load count analysis. Metode yang digunakan dalam analisis partisipasi masyarakat adalah penyebaran kuesioner dengan pembuatan kuesioner yang mengacu pada metode skala likert. Hasil penelitian ini menunjukkan bahwa TPS3R Gunung Anyar mampu menangani rata-rata 3.502 kg sampah per hari dengan densitas 264 kg/m³. Saat ini TPS3R Gunung Anyar memiliki tingkat pengurangan sampah mencapai 41,2% dengan residu 58,8%. Mayoritas masyarakat memiliki pengetahuan baik (72%) dan sikap positif (92%) terhadap pengelolaan sampah berbasis 3R, tetapi hanya 35% yang aktif berpartisipasi. Dua alternatif dianalisis sebagai rencana untuk meningkatkan pengurangan sampah. Alternatif pertama meliputi optimalisasi pemilahan dan jam kerja, dengan potensi pengurangan sampah 2.551 kg/hari (55%). Alternatif kedua, yang mencakup pengembangan lahan dan perubahan pihak ketiga, berpotensi mengurangi sampah hingga 3.244 kg/hari (70%). Abstract: Municipal solid waste generation in Gunung Anyar District Surabaya City has risen despite having TPS3R facilities. TPS3R Gunung Anyar is designed to handle municipal solid waste of 1,161 tons/year, but currently, it manages only 595 tons/year, with a residue rate of 48.7%, exceeding the acceptable limit of 30%. This study examines municipal solid waste management at TPS3R Gunung Anyar and determines the performance optimization to meet government solid waste reduction targets. Determination of municipal solid waste generation and composition was conducted based on SNI 19-3964-1994 and load count analysis. Community participation was assessed using Likert-scale questionnaires. TPS3R Gunung Anyar handled an average solid waste of 3,502 kg/day with a density of 264 kg/m³. The facility achieved a reduction rate of 41.2%, with a residue of 58.8%. Most of the community had good knowledge (72%) and a positive attitude (92%) toward 3R waste management, but only 35% actively participated. Two alternatives were analyzed to improve solid waste reduction. The first alternative is optimizing sorting and working hours, potentially reducing solid waste by 2,551 kg/day (55%). The second alternative involves expanding the facility and changing waste collectors, with a potential reduction of up to 3,244kg/day (70%)
