Abstract

Prasarana jalan merupakan salah satu infrastruktur penting dalam menunjang pertumbuhan ekonomi sebuah wilayah. Ketepatan pembangunan melalui investasi yang besar merupakan sebuah keharusan. Investasi jalan atau jembatan memiliki pengaruh yang luas tidak hanya bagi pengguna jalan dan jembatan, tetapi juga wilayah secara keseluruhan. Tujuan dari penelitian ini adalah untuk (1) mengetahui   total   waktu   optimal   paska   pelaksanaan   proyek pembangunan jalan Tinjomoyo-Sekaran dipercepat, dan (2) untuk mengetahui total biaya optimal yang harus dikeluarkan setelah pelaksanaan proyek tersebut dipercepat. Metode yang digunakan pada penelitian ini adalah CPM dan PERT. CPM digunakan tidak hanya untuk mengetahui durasi waktu yang dibutuhkan dalam penyelesaian proyek, tetapi juga untuk mengidentifikasi jenis pekerjaan kritis dalam pelaksanaan proyek. Berdasarkan perhitungan, metode CPM memerlukan waktu selama 128 hari untuk menyelesaikan proyek pembangunan jalan. Durasi tersebut lebih cepat sebanyak dua hari dibanding dengan perencanaan sebelumnya yang memerlukan waktu selama 130 hari. Dengan menggunakan metode PERT, estimasi biaya pelaksanaan proyek yang dapat dihemat adalah 13 hari, dari yang semula 143 hari menjadi 130 hari. Dengan menggunakan metode PERT dengan jalur kritis A, D, E dan F pembangunan Jalan Tinjomoyo Sekaran dapat diselesaikan dalam waktu 129,6 hari (dibulatkan menjadi 130 hari), yaitu sebesar 99,99%. Dengan menggunakan metode CPM, waktu yang dapat dihemat selama pelaksanaan proyek adalah 15 hari dengan penambahan biaya sebesar Rp 22.560.000,00. Dengan menggunakan metode PERT, waktu yang dapat dihemat adalah 13 hari, dari yang semula 143 hari, menjadi 130 hari dengan penambahan biaya sebesar Rp 16.920.000,00.

Abstract

The development of road infrastructure is a vital element in driving economic growth and improving the quality of urban life. In Semarang City, Jalan Gatot Subroto plays a crucial role as a major route connecting the north and south of the city, serving as a vital artery for inter-district mobility. However, in recent years, this road has faced serious challenges such as worsening traffic congestion, deteriorating road conditions, and their impacts on local social and economic activities. Therefore, efforts to enhance infrastructure on Jalan Gatot Subroto have become urgent given the complexity of these issues. This study aims to identify and determine variables that significantly influence the success of road improvement programs in the Gatot Subroto area of Semarang City. Data was collected using survey methods and deepened through interviews. The respondents involved in this study were 100 people with diverse backgrounds in terms of age and occupation. The collected data was then processed both quantitatively using SPSS and qualitatively to be used as a reference in answering research questions. Based on the analysis conducted, five variables are predicted to significantly affect the success of the road improvement project planned in the Gatot Subroto area of Semarang City: (1) User Satisfaction with a regression coefficient of 0.233, (2) Travel Time at 0.078, (3) Traffic Safety at 0.180, (4) Traffic Congestion at 0.163, (5) Accessibility at 0.551, and (6) Environmental Impact at 0.472. Referring to the field study results, it can be concluded that these variables have a significant relationship with the success rate of the Jalan Gatot Subroto improvement program in Semarang City, with important implications for more effective transportation infrastructure planning.

Abstract

The administrative areas of Pramukan District, Pusakajaya District, and Pusakanegara District in Subang Regency, West Java Province, which are located in the downstream part of the Cipunegara Watershed (DAS), are prone to flooding due to the overflow of the Cipunegara River. The impact of flooding can result in the collapse or damage of water structures. The aim of this thesis is to compare the elevation of the openings at the bottom of the Sadawarna Dam.In this thesis, data collection methods are used in the form of secondary data, literature studies from journals, theses, theses, books and the internet as references for working on this thesis. Analyzing the calculated discharge and hydrograph routing using the Nakayasu method, the maximum elevation to open the early realease door is an elevation of +80.10. If the water has reached an elevation of +80.10 then the early release door will be opened. The Dam Management Unit (UPB) will maintain water at this elevation so that there is no shortage of water and the water level can fall. During the rainy season, the gate will be opened when the water level reaches +80.10. Since the construction of the Sadawarna Dam, flooding in downstream areas, especially in the Indramayu area, has been reduced. The operational pattern of using early release gates also greatly reduces flooding because the water from upstream does not all flow directly downstream, the water is still stored in the dam and its output is measured through the spillway.
