Abstract

Musamus University is the only state university in South Papua Province. This campus provides parking spaces in various locations such as in the Faculty of Economics and Law, Deanery and Rectorate areas, but vehicles still often pile up. This research aims to determine the parking capacity of Musamus University. The research method is based on the 1998 Director General of Land Transportation's Technical Guidelines for the Implementation of Parking Facilities. The data collected is the number of incoming vehicles, the number of outgoing vehicles and the duration of the vehicle to find the value of the parking lot capacity. The results of the study at 3 points of the location of the motorcycle parking area of the Faculty of Economics and Law, the Deanery, and the Rectorate have a parking area of 216 m², 78 m², and 51 m², with a parking area requirement of 1,479 m², 289 m², and 231 m², then additional motorcycle parking areas are still needed, namely 1,263 m², 211 m², 180 m². In the car parking area of the Faculty of Economics and Law, the Deanery, and the Rectorate have a land area of 69 m², 80.5 m², and 57.5 m², a car parking area of 104 m², 173 m², and 173 m² is needed, so there is still a shortage of areas of 35 m², 92.5 m², and 115.5 m². The Faculty of Economics and Law's motorcycle prediction for the next 5 years is 312 SRP and cars 6 SRP.

Abstract

Pacal Reservoir is located in Kedungsource Village, Temayang District, Bojonegoro Regency, which functions to dam water from the Kedung River, which is a tributary of the Bengawan Solo River. Sedimentation is one of the main problems that occur in reservoirs, which causes a decrease in the operational life of the reservoir. Changes in land use can affect the sedimentation of the Pacal reservoir. This is caused by factors such as erosion, transportation and sedimentation that occur on the land. Changes in land use can increase land erosion, which can then increase sedimentation in reservoirs. This research aims to determine the level of sedimentation and its effect on the useful life of the Pacal Reservoir. From the research results, several conclusions were drawn relating to the sedimentation rate value in Pacal Reservoir in the 2013-2022 period as follows: The volume of suspended load was 24217.74 tons/year; Bed load volume is 45205.50 m³/yr; then the total value of sediment inflow is 92025.99 tons/year; The total sediment spread is 0.98 mm/yr. From the results of sedimentation calculations, the estimated remaining useful life of Pacal Reservoir is 30 years.

Abstract

The use of recycled plastic waste as a binder for paving blocks has been reported in a number of previous studies. However, most of these studies focus on feasibility and do not clearly explain how different plastic types behave mechanically over time. In this study, the compressive strength performance of paving blocks made from polypropylene (PP), polyethylene terephthalate (PET), and high-density polyethylene (HDPE) was experimentally compared using sand or fly ash as fillers. All mixtures were prepared with a fixed composition of 60% plastic and 40% aggregate. Compressive strength testing was carried out at 28 and 56 days using three specimens for each mix. The results show that the HDPE–sand mixture achieved the highest compressive strength at 28 days, reaching 15.7 MPa. Nevertheless, a noticeable reduction in strength was observed at 56 days, particularly in the HDPE-based mixtures. This reduction is mainly associated with polymer shrinkage and the development of interfacial stresses between the plastic binder and the aggregates. Overall, the results indicate that plastic-based paving blocks can meet the requirements of SNI 03–0691–1996 for light-duty applications, although their long-term mechanical stability remains a limitation that needs further attention.
