Abstract

Landslides are one of the most common disasters in Indonesia. Landslides are often triggered by high rainfall and occur for several days. Unstable soil structure is very easy to experience landslides. The case study of this research is in Pujon Sub-district, Malang Regency. Pujon sub-district has a hilly and highland topography. Its hilly-mountainous relief and steep slopes cause Pujon Sub-district to experience frequent natural disasters, especially landslides. The research was conducted by processing Sentinel 1 image using DInSAR method to obtain data on land surface change and weighting scoring method to obtain information on landslide prone areas. The processing of DInSAR method produces the value of vertical land surface change. The largest increase in land surface with a displacement value of 0.2972 m. And the largest land subsidence is -0.2234 m. Such movement can be an indicator of landslide occurrence. The GIS method produces 3 classes of landslide vulnerability level, namely low, medium and high in each year in Pujon sub-district. The average landslide prone area in the last 5 years is 15081.1331 ha. The processing results of DInSAR method and weighting scoring method can describe the landslide prone areas in Pujon Sub-district which is expected to be useful for landslide mitigation efforts.

Abstract

ABSTRACTIndustry has a level of intense competition in the free market era, even at the distributor level. Consumers will feel satisfied with the service of distribution, if the product arrives on time, the right amount and the right quality. PT. Mitra Aneka Rezeki partners have a problem with the lack of inventory when there is an order and its distribution system, such as delivery time, the number and type of goods delivered to each company destination and the cost of goods distribution. Resulting in the occurrence of shortages or excess inventory in the company in question. This study aims to plan the scheduling of product distribution activities to be well coordinate and minimal distribution costs with the optimal number of shipments using the DRP method. DRP is a method for handling inventory procurement in a multi echelon distribution network. From the results of the research, the distribution of companies during 2017 was 144 shipments at a cost of Rp. 3.037.509.720,-., when appling the DRP method, distribution will only be carried out as much as 40 times at a cost of Rp. 2.928.412.580,-,resulting in a decrease in cost of Rp. 109.097.140,- or 3,6 %..Keyword : Aktivity, Distribution, scheduling
