Abstract

The stability of the soil structure is something that needs to be considered in development. Increasing soil structure improvement can be done through various efforts using added materials or compaction processes. This study aims to improve the clay soil on the kerot kediri road using paper waste. The research was conducted experimentally by making samples in the laboratory. The land used is from the Totok Kerot road, Kediri, which has damaged the road surface due to land loans. Waste paper was added at 0% 7.5%, 10%, 15%, and 20% of the weight of the test object. Waste paper is used with pulp after it is dried and pulverized to a certain gradation. The tests carried out include the Consistency Limit (Atterberg Limit) and Soil Compaction (Proctor) tests. The results showed that the addition of waste paper affects the original properties of the soil. The addition of paper moisture content decreases the Plastic Index value and increases the dry volume of the soil. The addition of waste paper content also increases the volume of dry soil water but decreases after reaching the optimum point, namely at 10% paper waste content and 9.96% water content with a dry volume weight value of 1.97gr/cm3. The greater the dry volume of soil, the dry density indicates that the soil is getting higher. So that by knowing these results, it can be used as a reference in the process of repairing and backfilling the soil on the Totok Kerot Kediri road.

Abstract

Flood disasters frequently occurred in Jember Regency, East Java. It is usually caused by the overflow of the Tanggul River in the rainy season, especially in the downstream area. Flood control could be done by building dams, embankments, shortcuts, and other technical flood protections. Meanwhile, mitigation efforts such as developing thematic maps of flood inundation need to be done to minimize losses caused by the flood. This study aims to design a flood mitigation strategy technically. The flood control structure was proposed by designing a shortcut in Kali Tanggul. Its performance was analyzed to reduce flood inundation in the Tanggul watershed. The flood inundation modeling was carried out using spatial analysis using ArcGIS 10.1 and hydraulic analysis using HECRAS 5.0.3. Flood inundation results were compared with the Tanggul watershed flood map developed by UPT PUSDA Lumajang. Based on modeling results, flood control using shortcuts is considered an effective strategy for flood mitigation. It was indicated by the reduction of flood inundation distributions, flood inundation height, and flood-affected areas. The results show that the flood height decrease 0.47 up to 0.56 m

Abstract

The Papar intersection is a very congested route because the location is in the Kertosono-Kediri toll road planning area for the economic distribution of the Western and Southern East Java Provinces. There needs to be a traffic engineering management so that the intersection is not increasingly saturated. As a benchmark is the forecasting of traffic performance carried out for 2 years from 2019 to 2021. The intersection of the Simpang Papar due to the construction of the Kertosono-Kediri toll road will decrease the value of the DS by developing the Kertosono-Kediri toll road so that the DS value is below 1 (one). The lowest 2021 DS is 0.17, while the highest DS is 0.46. Based on the results of forecasting, the intersection of Papar after the construction of the Kertosono - Kediri toll road has increased the volume of traffic along with the growth in vehicle numbers. The lowest 2045 DS year is 0.94, while the highest DS is 2.51. The solution to dealing with traffic congestion in the year 2045 is by traffic monitoring, especially the signal settings and vehicle restrictions. Keywords : Traffic Performance, Degree of Saturation, Signal Intersection, Toll PlanningPersimpangan Papar adalah rute yang sangat padat karena lokasinya berada di area perencanaan jalan tol Kertosono-Kediri untuk distribusi ekonomi Provinsi Jawa Barat dan Jawa Timur Selatan.
