Abstract

Biofiisk alur Sungai Karang Mumus mempengaruhi karakteristik hidrograf aliran yang penting untuk diketahui adalah volume aliran air, debit banjir dan waktu sampai terjadinya debit banjir maksimum. Bentuk DAS kemiringan lereng geologi jenis tanah dan penutupan lahan merupakan karakteristik fisik yang akan mempengaruhi besarnya peningkatan aliran air permukaan sebagai respon curah hujan. Perubahan faktor biofisik memberikan dampak nyata terhadap volume peningkatan aliran air permukaan, terjadinya debit banjir maksimum, intensitas hujan dan waktu. Banjir merupakan suatu keadaan Sungai dimana aliran airnya tidak tertampung oleh palung Sungai karena debit banjir lebih besar dari kapasitas Sungai yang ada. Potensi daerah banjir berdasarkan peta topografi dan peta luas genangan banjir.

Abstract

Handling traffic accidents on Jl. Pangeran Antasari Samarinda City is inadequate. To determine the level of traffic accidents on Jalan Pangeran Antasari, Samarinda City, we refer to traffic accident data originating from the Samarinda City Police Traffic Unit, while to determine the condition of the road section it is obtained by survey and direct observation at the research location. In this study, the Accident Rate (AR) data analysis method was used to determine the accident rate, the Equivalent Accident Number (EAN) to obtain Accident Prone Areas (Blackspot) and the Upper Control Limit Method (BKA). From the results of this research, it was found that the highest accident rate occurred in In 2021, the number of accidents was 10 incidents. This road section is included in an accident-prone area with a percentage of 94% and an Upper Control Limit value of 23 in 2020. Human awareness of safety when driving is very low, therefore, increase concentration and caution when driving.

Abstract

East Kalimantan has great potential as a food production center in Indonesia, supported by the Sebakung Swamp Irrigation Area (DIR) which covers an area of ​​13,500 hectares with a functional area of ​​10,290 hectares. However, inefficient irrigation management and inadequate infrastructure maintenance have resulted in suboptimal land use and decreased agricultural productivity. This study aims to analyze the performance of the existing irrigation network and determine the budget required for its operation and maintenance. The study was conducted using field observations and regulatory guidelines, including Ministerial Regulation No. 12/PRT/M/2015 and No. 23/PRT/M/2017. The results of the study indicate that most irrigation channels are below Index 3, indicating significant sedimentation and vegetation growth that inhibits water flow. The overall channel condition index is 2.10 with a network functional level of 72.50%, while several water gates in certain villages are severely damaged with an Index classification of 4. The total operational cost of managing the irrigation network is IDR 292,300,000.00 which includes personnel incentives, monitoring, office operations, and equipment maintenance. Routine and periodic maintenance costs vary, with the highest budget allocated to Sri Raharja and Babulu Laut, totaling more than IDR 187,200,000.00. To improve irrigation performance, systematic management strategies such as routine dredging, vegetation control, and rehabilitation of priority infrastructure must be implemented. These efforts will improve irrigation efficiency, ensure optimal water distribution, and support agricultural productivity in East Kalimantan.
