Abstract

Abstract The population of Bandung City which increases every year causes traffic congestion problems, especially at many intersections, including signalized intersections. This study was conducted on a signalized intersection located on Jalan Soekarno Hatta-Mohammad Toha, in the City of Bandung. The data used is data obtained directly from the field, and the analysis was carried out with the help of the Vissim Program. This study shows that the majority of motorbikes move at an intersection with a speed of 35 km/hour. While the majority of light vehicles, buses, and heavy vehicles move at speeds of 36 km/hour, 39 km/hour and 35 km/hour respectively. During traffic congestions, the longest queues at this intersection occur at the intersection of Jalan Mohammad Toha towards U-S, with a length of 226 meters and an average of 186.14 m/hour, and at the intersection of Jalan Mohammad Toha towards S-U, with a length of 226 meters and an average of 116.57 m/hour. Keywords: signalized intersection; cross arms; speed; traffic congestion; queue Abstrak Jumlah penduduk Kota Bandung yang bertambah setiap tahun menimbulkan masalah kemacetan lalu lintas, khususnya di banyak simpang, termasuk di simpang bersinyal. Pada studi ini dilakukan kajian terhadap simpang bersinyal yang terletak di Jalan Soekarno Hatta-Mohammad Toha, di Kota Bandug. Data yang digunakan adalah data yang diperoleh langsung dari lapangan, dan analisis dilakukan dengan bantuan Program Vissim. Studi ini menunjukkan bahwa mayoritas sepeda motor bergerak di simpang dengan kecepatan 35 km/jam. Sedangkan mayoritas kendaraan ringan, bus, dan kendaraan berat bergerak dengan kecepatan masing-masing sebesar 36 km/jam, 39 km/jam, dan 35 km/jam. Pada saat macet, antrean terpanjang di simpang ini terjadi di lengan simpang Jalan Mohammad Toha arah U-S, dengan panjang 226 meter dan rata-rata 186,14 m/jam, dan di lengan simpang Jalan Mohammad Toha arah S-U, dengan panjang 226 m dan rata-rata 116,57 m/jam. Kata-kata kunci: simpang bersinyal; lengan simpang; kecepatan; kemacetan lalu lintas; antrean

Abstract

Optimal irrigation network performance is crucial to support agricultural productivity and meet the water needs of rice fields. However, the process of inventorying and assessing the condition of irrigation networks is still largely done manually, resulting in delays in reporting, potential recording errors, and low decision-making effectiveness. In accordance with the guidelines of Permen PUPR No.12/PRT/M/2015, a system is needed that is capable of evaluating the condition of irrigation assets more quickly, accurately, and in a standardized manner. This study aims to develop AsetAirKu, an AppSheet-based mobile application to support the process of inventorying and assessing the performance of irrigation channels and structures digitally, in an integrated manner, and in a way that is easy to use in the field. The research methods included a literature study on irrigation asset condition parameters, field data collection on channel profiles, sedimentation, embankment conditions, sluice gates, and other structure components, as well as the design of the application database structure. The application was developed through the stages of interface creation, data input flow, and report automation. The application was tested in the Kiaraenyeuh Irrigation Area as a case study, assessing its effectiveness during the data collection and assessment process in the field. AsetAirKu successfully integrated the data collection and assessment processes into a single platform. The field test results showed a network performance value of 70.65%, which is in the moderate category, with a moderate level of damage and recommendations for periodic maintenance. The application is capable of accelerating data recording, improving assessment accuracy, and generating reports automatically. The main constraint of the application is its dependence on an internet connection for data synchronization and report downloading. AsetAirKu has proven to be effective as a digital tool in assessing irrigation network performance, improving reporting efficiency, and supporting data-driven decision making.
