Abstract

The problem of flooding or inundation can arise from several factors, one of which is the incapacity of the existing drainage system to accommodate the increased volume of water flowing into it. For example, the drainage system on Jhoni Anwar Street in Padang City has become a frequent cause of flooding. This street should ideally be flood-free, especially as it serves as a major connecting road in Padang City. Therefore, the author intends to conduct research on the drainage system's capacity on this street. The data analysis required for this study includes hydrological analysis, including rainfall data, average rainfall, and flood discharge. Additionally, hydraulic analysis is also necessary, such as analyzing the existing channels, backwater analysis, planning the dimensions of the drainage system, and determining the flood points for each channel. It is known that the drainage system on Jhoni Anwar Street can only accommodate a water discharge of 0.24 m3/second, while the peak discharge during a 5-year flood period reaches 3.11 m3/second. Therefore, new dimensions for the drainage system are needed. The planned dimensions include a wet cross-sectional height of 140 cm or 1.40 m, a total cross-sectional height (h) of 160 cm or 1.60 m, and a channel width (b) of 1.42 cm or 1.42 m. With these dimensions, the channel will be able to accommodate a water discharge of 3.36 m3/second, in accordance with the criteria for peak flood discharge

Abstract

Proses penetasan telur unggas merupakan salah satu proses penting dalam budidaya peternakan unggas. Proses ini harus dilakukan dengan cermat dan teliti agar hasil penetasan dapat memuaskan. Namun, proses penetasan telur secara manual membutuhkan waktu dan tenaga yang cukup banyak dan terkadang belum efisien, sehingga dibuat rancangan alat penetas telur unggas otomatis kapasitas 360 butir. Alat ini menggunakan sistem pengontrolan yang dinamakan automatic computer control incubator. Tujuan dari penelitian ini adalah untuk merancang mesin penetas telur unggas otomatis yang digunakan untuk mempermudah dalam pengontrolan gerakan rak telur, suhu dan kelembaban udara. Proses perancangan dimulai dari survei lapangan untuk mengetahui kebutuhan alat yang akan dirancang dan kemudian dibuatlah desain dari mesin penetas telur unggas otomatis. Mesin ini berukuran 100 x 167 x 50 cm yang terdiri dari 6 (enam) buah rak untuk meletakkan telur unggas. Pada bagian atas mesin diletakkan kontroller inkubator untuk mengontrol secara otomatis pergerakan rak, suhu, dan kelembaban mesin

Abstract

Flooding is a frequent hydrometeorological disaster in the Dayeuhkolot Watershed, a sub-watershed of the Citarum River Basin, caused by high rainfall intensity and land cover changes. This study aims to project flood hydrographs in the Dayeuhkolot Watershed based on satellite rainfall data and land cover changes up to the year 2100. Rainfall data were obtained from GSMaP for the period 2018–2022 and calibrated using the quantile mapping method to match observed rainfall characteristics, while river discharge data were collected from the AWLR monitoring station operated by PJT II. Land cover analysis was conducted using Sentinel-2 imagery for the period 2017–2021 and projected to the year 2100 using the Malaccha method. Rainfall–runoff modeling was performed using the HEC-HMS software with the Soil Conservation Service (SCS) Synthetic Unit Hydrograph method. Model performance was evaluated using Nash–Sutcliffe Efficiency (NSE) and Root Mean Square Error (RMSE). The results show that out of 12 flood events analyzed, six models met the performance criteria with NSE values greater than 0.36. Land cover projections to 2100 indicate minor changes in forest areas, leading to an increase in the Curve Number value from 76.90 to 77.00, which resulted in a 0.33% increase in peak flood discharge from 2021 to 2100. These findings demonstrate that land cover changes influence flood hydrograph characteristics and can serve as a basis for flood mitigation planning in the Dayeuhkolot Watershed.
