Abstract

The inconsistency in the quality of paving blocks can result in uneven road surfaces, thereby increasing the risk of traffic accidents. This study aims to determine the compressive strength quality of Holland-type paving blocks from several producers in the city of Semarang, both those made manually and by machine, as well as to understand the reasons behind the dimensional inconsistencies of Holland-type paving blocks from various producers in the city. The research samples were taken from four paving block producers located in Semarang. The test results show that all paving block products from the four different producers meet or exceed the minimum compressive strength values set in SNI 03-0691-1998. This indicates that the products are theoretically capable of withstanding the applied compressive loads. The compressive strength test shows the lowest average value from producer AB at 17.21 MPa, while the highest average value was achieved by producer ADS at 19.3369 MPa. The dimensional inconsistencies of Holland-type paving blocks from several producers in Semarang can be attributed to various factors, including differences in production processes between producers, variations in the raw materials used, and differences in the settings of machines or production equipment.

Abstract

Transportation is an important means to support the success of development and to facilitate economic activities in the community. Economic growth in Tegal Regency has resulted in increased mobility, which requires efforts to improve service quality and add effective transportation infrastructure. In order to improve transportation in Tegal Regency, the government has implemented a policy to relocate and build a representative Type C transport terminal with the aim of solving traffic problems in the Central Business District (CBD) area of Tegal Regency. Relocating the Type C transport terminal in Tegal Regency is necessary to improve the effectiveness of terminal relocation. Therefore, a study was conducted on the Optimization of Type C Terminal Relocation Utilization in Tegal Regency (Case Study: Dukuhsalam Village, Slawi District, Tegal Regency) using a quantitative descriptive research method to find out the effectiveness of terminal relocation. The analysis conducted includes technical analysis, economic analysis, traffic analysis, and environmental analysis. Based on the results of the analysis, it was concluded that terminal relocation is considered effective. The technical analysis shows that the infrastructure and facilities of the new terminal are more complete compared to the revitalization of the old terminal. Economic analysis shows that the return on investment for the new terminal can be achieved 2 years faster compared to revitalizing the old terminal. Relocating the new terminal can reduce congestion costs by IDR 1,158,096.00 per day and reduce environmental damage costs by IDR 1,414,088.93. Therefore, optimizing the Type C terminal in Tegal Regency can be achieved by relocating it to a new location.

Abstract

This study aims to analyze road users' perceptions of pedestrian facilities in the Pemuda Corridor (Lawang Sewu – Mall Paragon), Semarang City. Variables such as safety, comfort, accessibility, and infrastructure quality are the focus of this research. Data were collected through questionnaires with a sample of 400 people, field observations, and interviews. Field study results indicate that despite many positive aspects of the current pedestrian pathways in the Pemuda Corridor, there are still deficiencies that need improvement. Certain areas require additional zebra crossings and traffic lights to enhance safety. Furthermore, cleanliness and maintenance of the sidewalks in some spots are still suboptimal. Accessibility for people with disabilities also needs enhancement, as there are still obstacles such as vehicles and vendors occupying the pedestrian paths. The physical condition of the pedestrian pathways is generally good, but some areas require upgrades. These findings imply the need for municipal government intervention to improve the safety, comfort, and accessibility of pedestrian pathways through the addition of safety facilities, stricter enforcement of regulations, and regular maintenance programs. Involving the local community in the planning and management process of pedestrian pathways is also recommended to identify problems more effectively and develop solutions that meet community needs. With these steps, it is expected that pedestrian facilities in the Pemuda Corridor and other areas in Semarang City can be improved to create a safer, more comfortable, and inclusive environment for all pedestrians.

Abstract

Ketersediaan angkutan sekolah yang layak dapat menjadi alternatif solusi bagi pemangku kepentingan untuk merubah perilaku pelajar yang saat ini banyak menggunakan kendaraan pribadi dalam melakukan perjalanan kesekolah. Kondisi ini dinilai tidak efisien, mengingat dampak yang ditimbulkan. Jaminan ketepatan waktu, kenyamanan, keselamatan, dan keamanan dalam perjalanan menggunakan moda transportasi angkutan sekolah menjadi parameter hasil kajian efektivitas angkutan sekolah di Kota Tegal. Hingga saat ini, pelayanan angkutan umum di kota Tegal dinilai masih belum dapat bekerja secara optimal. Tidak optimalnya fungsi layanan angkutan umum di kota Tegal, dianggap menjadi salah satu penyebab tingginya tingkat penggunaan kendaraan pribadi dikalangan pelajar. Oleh karena itu, penyediaan jasa angkutan sekolah yang layak dapat menjadi salah satu solusi alternatif untuk mengatasi kepadatan arus lalulintas di kota tersebut, khususnya pada jam sibuk seperti jam berangkat dan pulang sekolah. Hasil penelitian ini juga menunjukkan bahwa minat pelajar dalam menggunakan jasa angkutan sekolah masih cukup tinggi, dengan catatan bahwa moda transportasi yang dimaksud mampu menjangkau daerah dimana para pelajar tinggal.

Abstract

Floods and Rob floods are natural disasters that often occur in Indonesia. The UNISSULA campus area is in the Pantura road area. UNISSULA is one of the campuses affected by floods and robs. Extreme weather conditions and rising sea levels have exacerbated the condition of the north coast road. Thus causing traffic jams and activities of the surrounding community to falter.The purpose of this study was to analyze the drainage system of the UNISSULA campus area by utilizing the potential of a storage pond by disposing of water directly into the estuary. With this research, it is hoped that it can be used as data and material for consideration for the development of a drainage system in the campus area and to become a pilot campus to control flooding. The method used is a simulation of the rainfall-runoff model using EPA SWMM Version 5.1.This study carried out two scenarios in carrying out flood control efforts, namely the first scenario, the existing west, and east retention ponds will be connected to pond 1, for the pond in the north, will be connected from pool 4 to the engineering pool, channeled to pool 3, to pool 2 and connected with pool 1 equipped with a pump with a capacity of 1 m3/sec with additional long storage from pool 2 to pool 1 along 184 meters. The second scenario is to break the direction of the front and rear drainage flows. For drainage, it will be pulled into pond 4, then a technical pond until it is connected to pool 2 and discharged directly into the sea with a flood pump with a capacity of 0.5 m3/sec. This makes the flood travel time short and is expected to reduce inundation. With this scenario, it can also be developed as Khairu Ummah Edu-tourism Khaira Ummah in the campus area.

Abstract

Penelitian ini mengevaluasi modifikasi aspal dengan resin katalis untuk ketahanan terhadap banjir rob di Pantura Semarang-Demak, dengan pengujian perendaman selama 7, 14, dan 21 hari. Hasil menunjukkan bahwa aspal dengan resin katalis, kecuali komposisi 4%-2% dan 4%-4%, masih layak digunakan setelah 7 hari perendaman. Namun, setelah 14 dan 21 hari, semua komposisi tidak memenuhi standar teknis Bina Marga, terutama karena nilai rongga udara yang melebihi batas. Semakin lama perendaman dan semakin tinggi komposisi resin serta katalis pada Asphalt Concrete Wearing Course (AC-WC) yang terendam rob, nilai VIM meningkat, menyebabkan lebih banyak rongga dan menurunnya daya tahan. Komposisi 4% Resin dan 0% Katalis dengan perendaman 7 hari memenuhi Spesifikasi Teknis Bina Marga 2018 revisi 2. Perendaman terus-menerus juga berdampak negatif pada stabilitas, meningkatkan risiko deformasi permanen, bleeding, dan stripping. Keyword : Rob, Aspal Modifikasi, Stabilitas
