Abstract

Berangkat dari permasalahan bahwa bangunan di kompleks Kantor Kepala Desa Kenalan sudah memerlukan penyesuaian, dengan  redesain bangunan sehingga tercipta efisiensi lahan di lingkungan Kantor Desa Kenalan. Setelah menjadi desa wisata di tahun 2017, dan dibangunnya Balai Ekonomi Desa (Balkondes) sebagai prasarana pariwisata oleh BUMN, bersebelahan dengan kantor Pemerintah Desa Kenalan, Aktivitas warga meningkat dengan mulai berdatangannya pengunjung, dan akibat keterbatasan lahan pengunjung memarkir kendaraannya di halaman kantor desa. Dampaknya timbul ketidaknyamanan di lingkungan kantor, terutama bagi kegiatan sekolah PAUD. Pemecahan masalah utama lingkungan PAUD dengan pembuatan desain bangunan baru sehingga murid bisa beraktifitas belajar dan bermain di dalam ruang kelas maupun di taman tanpa terganggu. Lahan yang tersedia sangat terbatas dan memiliki kontur cukup ekstrim, tetapi memiliki potensi alam sungai dan kebun yang memberikan iklim sejuk. Maka dibuat desain bangunan yang menyesuaikan kondisi tersebut, memperhatikan kekuatan konstruksi, estetika, tetapi juga efisiensi bahan, Pada bagian lahan berkontur menggunakan ketinggian lantai berjenjang, sehingga dapat membentuk bangunan dua lantai, dengan fungsi PAUD di dasar dan kantor desa di lantai atas. Bangunan didesain menggunakan konstruksi batu kali, dinding bata, dan memanfaatkan udara alami dengan ventilasi bersilang sehingga memberi keamanan dan kenyamanan pengguna. Pembuatan ramp sebagai pengganti tangga dan pemagaran tepi sungai untuk keamanan siswa.

Abstract

Floods are natural disasters that we often encounter during the rainy season. Apart from there are also tidal floods which are caused by global warming, this problem occurs in the city of Semarang, especially North Semarang, specifically the north coast of the Java Sea. Floods that occurred in 2021 in the city of Semarang include Starting from Genuk, Kaligawe, Satsiun Tawang, Tanjungmas, Karangayu, the flood disaster was caused by high rainfall, while tidal floods caused high tides and inundated roads and houses of residents on the north coast of Semarang city. To handle this problem, the government Currently we have made embankments, namely making embankments including the Sringin River which is equipped with a ponpa, Tenggang River, Babon River, Semarang River, Banger River, and others. These embankments are equipped with pumps so that when the water from upstream to downstream is high, the water is pumped. to the sea, the aim is to find out one of the annual discharges of the river, namely the Babon, and to find out the tamping capacity of the Babon River Longstorage. Apart from that, there is a method for handling tidal floods, namely using the Babon River Longstorage which is equipped with a pump, if there is high tide which inundates roads and houses. residents then the pump is turned on, whereas if the water recedes and does not inundate residential areas then the pump is turned off. Flood control analysis is calculated using the HEC-RAS program simulation using a return period of 50 years. Based on calculations using the HEC-HMS program. The flood discharge is 2,529 m3/sec. The high tide elevation is + 1.67 m, while the normal water level is -0.5 m.

Abstract

The Pakijangan River Basin in Brebes Regency plays a critical role in supplying raw water for domestic, agricultural, and environmental needs. However, the absence of continuous streamflow records and increasing pressure on water resources pose significant challenges to effective management. This study aims to quantitatively estimate water allocation within the basin through a water balance approach. The methodology includes field surveys of existing conditions, analysis of water demand and availability, and water balance simulation using the RIBASIM (River Basin Simulation) model integrated with the Sacramento rainfall-runoff method. Rainfall data were obtained from two representative manual stations: Klampok and Slatri. Simulation results indicate that the Pakijangan Basin remains in surplus throughout the year, with dependable flow sufficient to meet all domestic and non-domestic water demands. With a distribution efficiency indicator (K factor) of 1, the basin even has the capacity to supply neighboring basins (Pemali River Basin) at a rate of 0.1 m³/s. These findings serve as a valuable foundation for sustainable, equitable, and efficient water resource planning and management in the region

Abstract

Wonosobo is one of the tourist destinations in Central Java, making highways a vital element in supporting the mobility of both residents and visitors. One of the strategic roads is Jalan KH. Abdurahman Wahid, which connects the center of Wonosobo City with the Dieng Tourism Area. The surface condition of this road segment shows various types of damage that have the potential to disrupt transportation flow. This study aims to analyze the surface layer damage on Jalan KH. Abdurahman Wahid from STA. 0+000 to STA. 1+950 in Wonosobo District using two approaches: the Pavement Condition Index (PCI) method and the Bina Marga Method. The PCI method is used to evaluate the extent of damage based on visual inspection results, while the Bina Marga Method is employed to identify types of damage and determine their handling priority levels through the calculation of Priority Order (Urutan Prioritas/UP). The survey and analysis results indicate eight types of damage based on the Pavement Condition Index (PCI), with an average PCI score of 35.62 (categorized as Very Poor), and the lowest score of 20 (categorized as Serious) found in sample units 3, 10, and 13. According to the Bina Marga Method, six types of damage were identified with a Priority Order (UP) value of 6, indicating that the road segment falls into the priority category for Periodic Maintenance. It can be concluded that this road segment requires immediate treatment either in specific sections or along the entire stretch. The analysis results are expected to serve as a consideration for relevant agencies in managing road infrastructure effectively and sustainably.

Abstract

This study aims to analyze the Marshall characteristics and retained stability of Asphalt Concrete-Wearing Course (AC-WC) mixtures incorporating Low-Density Polyethylene (LDPE) plastic with variations in immersion duration. The research was motivated by the premature deterioration of pavement structures caused by water infiltration and the quality of asphalt mixtures. An experimental laboratory method was employed in accordance with the 2018 General Specifications of Bina Marga, including the determination of the Optimum Asphalt Content (OAC), specimen preparation, and Marshall as well as retained stability testing with immersion periods of 1 and 4 days and LDPE contents of 6%, 9%, and 12%. The results indicated an Optimum Asphalt Content (OAC) of 5.88%. The highest stability values were obtained from the mixture containing 12% LDPE, reaching 2360.23 kg after 1 day of immersion and 1936.87 kg after 4 days of immersion. Flow values and volumetric parameters (VIM, VMA, and VFA) generally satisfied the specification requirements. The highest retained stability values reached 96.0% for the 1-day immersion period and 104.5% for the 4-day immersion period, while the lowest value was 84.0%. Although stability decreased with increasing immersion duration, most mixtures still met the minimum specification requirements. It can be concluded that the incorporation of LDPE into AC-WC mixtures enhances Marshall characteristics and improves resistance to water-induced damage.

Abstract

The Kaliwungu–Krapyak Toll Road is one of the road sections that connects Kendal Regency and Semarang City and is part of the Trans Java Toll Road network. Differences in traffic conditions and road characteristics between toll roads and non-toll roads can affect the magnitude of Vehicle Operating Costs (VOC) incurred by road users. This study aims to identify the variables that influence Vehicle Operating Costs (VOC) and to analyze the VOC values on the Kaliwungu–Krapyak Toll Road and the Kaliwungu–Krapyak Non-Toll Road using the Pacific Consultant International (PCI) method. The research data were obtained through the collection of primary and secondary data related to vehicle operating cost variables, including fuel consumption, lubricant usage, vehicle maintenance costs, tire wear, vehicle depreciation, capital interest, insurance costs, and unexpected costs. The results show that the VOC value is influenced by vehicle speed and traffic conditions on each road segment. The lowest VOC value on the Kaliwungu–Krapyak Toll Road occurs at a speed of 70 km/h, while on the Kaliwungu–Krapyak Non-Toll Road it occurs at a speed of 57 km/h. Based on these results, the analysis of VOC variables can be used to describe the efficiency of vehicle operating costs on both road sections.
