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.

Abstract

ABSTRACTHigh-quality road infrastructure is a crucial foundation for economic development and community mobility. However, many road projects often fail to meet expected standards, causing losses for both the government and the public. Previous studies have highlighted various technical and managerial weaknesses. This study offers a novel perspective by deeply examining regulatory and institutional aspects while providing practical recommendations for their improvement. A case study approach was employed, involving project managers, contractors, field supervisors, and affected community members as research participants. Data were collected through in-depth interviews, direct observation, and document analysis, followed by qualitative analysis methods. The findings reveal that the use of substandard materials, improper construction techniques, suboptimal project management, and non-compliance with regulations—exacerbated by budget constraints, poor coordination, and weak oversight—contribute to substandard project outcomes. The primary contribution of this study lies in providing actionable insights to enhance regulatory frameworks, strengthen oversight mechanisms, and build institutional capacity to ensure road infrastructure quality aligns with public and governmental expectations.Keywords: Road Project Management, Road Infrastructure Management, Road Project Regulations, Road Quality.ABSTRAKInfrastruktur jalan yang berkualitas adalah fondasi penting bagi perkembangan ekonomi dan mobilitas masyarakat. Namun, banyak proyek jalan sering gagal mencapai standar yang diharapkan, merugikan pemerintah maupun masyarakat. Penelitian sebelumnya telah mengungkap berbagai kelemahan teknis dan manajerial. Penelitian ini menawarkan kebaruan dengan menyoroti secara mendalam aspek regulasi dan kelembagaan serta memberikan rekomendasi praktis untuk perbaikannya. Pendekatan studi kasus digunakan, melibatkan manajer proyek, kontraktor, pengawas lapangan, dan masyarakat terdampak sebagai peserta penelitian. Data dikumpulkan melalui wawancara mendalam, observasi langsung, dan analisis dokumen, kemudian dianalisis menggunakan metode kualitatif. Hasil penelitian menunjukkan bahwa penggunaan material yang tidak sesuai standar, teknik konstruksi yang kurang tepat, manajemen proyek yang tidak optimal, dan ketidakpatuhan terhadap regulasi—yang diperburuk oleh keterbatasan anggaran, koordinasi yang buruk, dan lemahnya pengawasan—berkontribusi pada hasil proyek yang tidak memenuhi standar. Kontribusi utama penelitian ini terletak pada pemberian wawasan implementatif untuk meningkatkan kerangka regulasi, memperkuat mekanisme pengawasan, dan membangun kapasitas kelembagaan guna memastikan kualitas infrastruktur jalan sesuai dengan harapan masyarakat dan pemerintah.Kata Kunci: Manajemen Proyek Jalan, Pengelolaan Infrastruktur Jalan, Regulasi Proyek Jalan, Kualitas Jalan.

Abstract

The development of road and transportation infrastructure in Tangerang Regency is crucial for economic growth. The increasing number of vehicles on Jalan Raya Serpong-Cisauk, without adequate infrastructure development, has led to traffic volumes exceeding capacity. The solution implemented to reduce queue length and delays is the construction of a flyover. This study employs quantitative and qualitative methods, with primary data including traffic volume, free flow speed, and side friction, while secondary data is sourced from relevant agencies. The analysis is conducted using PKJI, VISSIM, and SWOT methods. The results show an increase in road capacity after the construction of the Cisauk flyover, with a decrease in the Dj ratio from 2.38 to below 1.00, and improved LOS from F to C/B during holidays and D/C on weekdays. However, surrounding businesses experienced negative impacts, including revenue decline and business relocations.

Abstract

Madukoro area in Semarang City is a residential, business, shopping, education, office, and warehousing area in the northern coastal area of Tawangmas Village in West Semarang District. Flooding problems have practically disrupted the activities of the area. The drainage system is the root cause of the problem, coupled with the contour and topography of the land which is almost flat without slopes, so it requires an evaluation of the drainage system by recalculating the hydrological and hydraulic aspects and the need for sufficient flood pump performance to overcome flood problems in the Madukoro area. The evaluation of the drainage system includes planning the modeling of the flood pump area. The calculation of the planned flood discharge uses EPA SWMM version 5.1 modeling for a 5-year period and to calculate the frequency analysis of hydrological data using Aprob_4.1. The modeling of an area of 55 ha with restrictions on the catchment area of the Madukoro area which is limited by the Semarang Indah channel on the South side, and the West to North sides are limited by Jl. Arteri Yos Sudarso, and the East side is limited by Kanal Banjir Barat. The calculation of the planned flood discharge is 12.36 m3/s at the Madukoro long storage. From the results of the planned flood discharge, the Madukoro long storage is designed using 2 pumps with a capacity of 1.5 m3/s by maintaining 1 existing pump installed at the location with a capacity of 1.5 m3/s and utilizing 2 existing pumps with a capacity of 0.6 m3/s. For long storage planning, the dimensions are adjusted to existing conditions, namely a width of 6 m with a designed depth of 1.8 m to 3.00 m, a length of 551 m, and the water level is maintained at a depth of 0.4 m to 1.0 m from the bottom of the channel. Meanwhile, the elevation planning of the embankment still uses the existing elevation. Water gates are made at the intersection of the Semarang Indah channel and the Madukoro channel, and at the warehouse location bordering Kanal Banjir Barat.

Abstract

Subdistrict office buildings, as public service infrastructure, play an important role in supporting government functions at the regional level. However, many office buildings are physically damaged or do not meet administrative requirements. This study aims to evaluate the suitability of district office buildings in Tegal Regency based on technical and administrative aspects in accordance with Ministry of Public Works and Housing Regulation No. 29/PRT/M/2006 and Law No. 28 of 2002 on Building Structures. The study was conducted on seven district offices: Bumijawa, Balapulang, Lebaksiu, Pagerbarang, Adiwerna, Talang, and Kramat. The methods used included a visual survey of structural, architectural, and utility elements with a weighting system (structure 40%, architecture 35%, utilities 25%) as well as an examination of administrative documents such as Land Certificates, KIB, IMB, and SLF. The research results showed that Talang Subdistrict had an average score of 1.41 and was categorized as Suitable. Bumijawa District (1.94), Balapulang District (1.98), and Lebaksiu District (2.01) are classified as Conditionally Feasible. Meanwhile, Pagerbarang District (2.74), Adiwerna District (2.63), and Kramat District (2.77) are categorized as Not Feasible. From an administrative perspective, none of the subdistricts have building permits (IMB) or site clearance certificates (SLF), resulting in an average administrative score of only 2 out of 4 points (50%). This study recommends gradual improvements, prioritizing technical rehabilitation budgets, and expediting the processing of legal documents to enhance the suitability of subdistrict office buildings

Abstract

ABSTRAKEmisi karbon dioksida (CO2) dari sektor transportasi perkotaan menyebabkan pencemaran udara dan permasalahan global di suatu kota. Meski mendorong mobilitas dan pertumbuhan ekonomi, sektor ini mengancam keberlanjutan lingkungan. Penyediaan ruang terbuka hijau (RTH), terutama yang bersifat publik, berperan sebagai solusi efektif dalam menyerap emisi CO2 melalui vegetasi perkotaan. Penelitian ini bertujuan untuk mengetahui timbulan emisi CO2 transportasi perkotaan dan kapasitas daya serap RTH terhadap emisi tersebut berdasarkan empat studi kasus. Penelitian ini menggunakan pendekatan deskriptif melalui metode literature review. Dari temuan penelitian mengindikasikan bahwa ruang terbuka hijau (RTH) publik di wilayah perkotaan belum mampu menyeimbangkan volume emisi CO2 dari transportasi, dimana volume emisi CO2 sangat dipengaruhi dari jumlah dan jenis kendaraan bermotor, sedangkan kinerja RTH dipengaruhi oleh luas, tipe dan jenis vegetasi.Kata Kunci: Daya Serap Tanaman, Emisi Karbon Dioksida, Ruang Terbuka Hijau, TransportasiABSTRACTCarbon dioxide (CO2) emissions from the urban transportation sector cause air pollution and global problems in cities. Although it promotes mobility and economic growth, this sector threatens environmental sustainability. The provision of green open spaces (RTH), especially public ones, plays an effective role in absorbing CO2 emissions through urban vegetation. This study aims to determine the CO2 emissions from urban transportation and the absorption capacity of RTH against these emissions based on four case studies. This study employs a descriptive approach using a literature review method. The findings indicate that public green open spaces (RTH) in urban areas are unable to balance the volume of CO2 emissions generated by motor vehicles, where the volume of CO2 emissions is significantly influenced by the number and type of motor vehicles, while the performance of RTH is influenced by its area, type, and vegetation.Keywords: Plant Absorption Capacity, Carbon Dioxide Emissions, Green Open Spaces, Transportation
