Abstract

Irrigation networks play a strategic role in ensuring water availability for agricultural production. This study was conducted in the Purworejo Irrigation District in Tunjungtirto Village, Singosari Subdistrict, Malang Regency, with a service area of 128 ha. The study aimed to assess the physical condition and operational functionality of the network and to determine the Irrigation System Performance Index as a basis for formulating remedial measures. The research approach involved direct field surveys combined with quantitative assessments using performance evaluation parameters for irrigation infrastructure. The aspects analyzed included the structural stability of the facilities, the operational reliability of the water gates, the smoothness of flow distribution, the level of sedimentation, and the condition of supporting facilities. The findings revealed infrastructure degradation characterized by concrete cracks, deterioration of the lining, corrosion of metal components, and sediment buildup that reduces flow capacity. Based on the calculations, the physical performance index reached 47.83%, which falls into the “severely damaged” category with a high level of functional impairment. These conditions indicate that water distribution services are not yet operating optimally. Therefore, a comprehensive rehabilitation program is needed, including structural repairs, channel cross-section normalization, replacement of control devices, and improvements to the drainage system to restore the irrigation network’s performance in a sustainable manner.

Abstract

The Lang-Lang Irrigation Network (JI), located in Singosari Subdistrict, Malang Regency, plays a vital role in supporting the productivity of 98 hectares of agricultural land. The Lang-Lang Irrigation Network (JI) is one of 717 irrigation networks (JI) in Malang Regency. Geographically, the service area of the Lang-Lang Irrigation Network (JI) is highly complex as it stretches from Ngenep Village to Lang-Lang Village, traversing an area with a mix of dense settlements and agricultural land. These conditions create the potential for dual pressures on the irrigation network: technical challenges in maintaining efficient gravity flow, and non-technical challenges in the form of potential disruptions (such as trash dumping or illegal tapping) due to proximity to densely populated settlements. The survey design for the irrigation system performance assessment analysis is based on Ministry of Public Works and Public Housing Regulation No. 12/PRT/M/2015. The analysis process integrates qualitative findings from field inspections with quantitative calculations using the Irrigation Structure Performance Index. The analysis results indicate that, in general, the infrastructure along the 500-meter-long Lang-Lang JI primary channel is in a state of Minor Damage (RR), with a physical assessment weight of 82.50%, and 17.50% falls into the category requiring periodic maintenance of a preventive nature. Meanwhile, the results of the assessment of the physical condition of irrigation infrastructure—specifically control and auxiliary structures—show that 74.44% are in a state of moderate damage (MD), and 25.56% fall into the category requiring periodic maintenance in the form of repairs.

Abstract

There is a relatively large volume of traffic at the intersection without traffic lights on Jalan Raya Bandulan, Jalan Barat, and Jalan Bandulan in Sukun District, Malang City. This intersection does not yet have a traffic signal device (APILL). Especially during rush hour, this condition often causes vehicle congestion, which leads to irregular traffic and frequent traffic jams. This study uses a quantitative research design with a descriptive research type. Primary and secondary data are needed for proper data collection. This study aims to determine traffic performance at the intersection of Jalan Raya Bandulan, Jalan Barat, and Jalan Bandulan in Sukun District, Malang City. The results of the performance analysis at the intersection show that vehicle delays are relatively substantial, with congested traffic flow, long queues, and vehicle speeds dropping to less than 30 km/hour. Vehicle speed and volume can decrease to almost zero in some circumstances, especially when there are long queues, even when the reported traffic volume is not too high. This intersection is classified as service level E according to the service level assessment. The average delay per vehicle is 34.85 seconds, indicating that traffic conditions are approaching saturation and require more control.

Abstract

Formwork that is often used in construction projects is multiplex formwork. Multiplex is formwork made of wood and is classified as conventional formwork that is also resistant to moisture. Multiplex is an efficient formwork material because it is easy to produce, economical, and flexible to use, even in constructions with complex designs. The use of efficient and effective construction materials is an important aspect of building design, especially in the context of multi-story building construction. In recent years, the use of multiplex as a construction material for floor and beam formwork has gained greater attention. Multiplex, which is made of bonded layers of wood, has various advantages, such as being lightweight, easy to install, and reusable. The selection of formwork installation methods determines the quality of concrete that can be achieved, because formwork that is too difficult to install or takes too long to reuse will result in suboptimal concrete work. Based on the formwork material shrinkage value on each floor, for example on the first (second) floor with a shrinkage value of 100%-93.45%=6.55% while the shrinkage value on the second floor (third) reaches 100%-88.84%=11.16%, and the effectiveness of repeated formwork use in formwork work is the reuse of formwork on the first floor (first) by 93.45% and on the second floor (second) by 88.84%.

Abstract

Transportation services connecting major cities play a vital role in facilitating public mobility, particularly along the Malang–Jakarta route, which has a high passenger volume. The two main options available are bus services and executive trains, both of which offer comparative advantages in terms of travel time, fares, and accessibility. This study is designed to explore the user profiles of these two modes, identify the determinants shaping mode choice preferences, and develop a mathematical model for predicting mode choice along the Malang–Jakarta corridor. The research approach adopts the stated preference technique, with data collected directly through a survey distributed to 100 bus users and 100 train users. The evaluated parameters include fare variations, differences in travel time, time differences to reach the terminal or station, and variations in departure schedules. The applied analytical techniques are multiple regression and the binomial logit model. The findings indicate that fare and accessibility factors have a dominant impact compared to other variables in determining mode choice. The resulting prediction model is capable of describing fluctuations in the probability of use between buses and trains in response to changes in service attributes. This research is expected to provide practical insights for transportation operators and policymakers in optimizing service standards and designing more efficient intercity transportation systems.
