Abstract

PT. XYZ merupakan sebuah perusahaan manufaktur yang bergerak dibidang otomotif dan sudah berjalan sebagai supplier komponen otomotif untuk beberapa perusahaan otomotif terkemuka di Indonesia. Kebanyakan proses produksi pada PT. XYZ sudah berjalan dengan baik. Tetapi terdapat salah satu sub produk mereka yang memiliki kendala dalam proses produksinya yaitu muffler K-59J. Pada lintasan produksi muffler K-59J dinilai kurang optimal dalam proses produksinya. Hal tersebut dilihat dari banyak kendala yang timbul selama proses produksi berlangsung. Mulai dari terjadi penumpukan (bottleneck), Target produksi harian sering tidak tercapai sehingga sering terjadi waktu kerja tambahan (overtime), dan jika dilihat secara data nilai efisiensinya hanya sebesar 58,81 %. Dengan demikian, penelitian ini bertujuan untuk meningkatkan performa dari lintasan produksi tersebut. Oleh karena itu diusulkan metode Algoritma Genetik yang bersifat komputerisasi untuk meningkatkan performanya. Proses penyelesaian penelitian ini dilakukan dengan bantuan program matlab dalam pengerjaan metode Algoritma Genetik. Pada prosesnya, dilakukan beberapa tahapan mulai dari membuat representasi genetik, menyeleksi populasi induk, melakukan rekombinasi dan mutasi, dan regenerasi populasi. Tetapi terdapat sedikit perbedaan pada penlitian ini dimana populasi awal yang dibentuk merupakan populasi yang sudah tersaring kedalam syarat-syarat keseimbangan lintasan antara lain sesuai dengan diagram alurnya, dan jumlah waktu stasiun kerja tidak melebihi cycle time. Dari hasil pengerjaan metode Algoritma Genetik tersebut, didapatkan besar efisiensi lintasan sebesar 74,07 % dengan total stasiun kerja sebanyak 18 stasiun kerja. dengan demikian nilai efisiensi lintasan berhasil ditingkatkan sebesar 15,26 %.

Abstract

Province X in Indonesia has a significant problem with trash that has been challenging to address. The Environment Agency therefore desires to construct an inorganic Trash Management System. The Environment Agency has four potential locations with various capacities. The purpose of this research is to locate a trash treatment system's best possible site and allocate each TPS that is less than 30 km and more over 30 km from the chosen system, respectively, to ensure that the overall distance traveled is as little as possible. There are four possible locations, and it required to select three of them. This study use the LINGO 18.0 software to solve the Capacitated Maximum Covering Location Problem (CMCLP) approach. Distance parameters used by CMCLP are split into two stages. The first stage is to determine the location of the trash treatment system to be built and the allocation of trash and the amount of trash from each TPS using Mix Integer Programming. B is not chosen out of the options, which are A, B, C, and D. System A will receive 1,407,520 tons of trash totaling 24 TPS. System C receives trash from 147 TPS weighing 1,294,495 pounds. System D will receive trash weighing 819,142 tons from 88 TPS. The allocation of trash from TPS that are more than 30 km away takes place in the second stage. Three TPS are assigned to System A, and seven TPS are assigned to System D.

Abstract

While prior research has provided insights into challenges and capabilities related to effective Big Data use, much of this contribution has been conceptual in nature. The aim of this study is to explore such challenges and capabilities through an empirical approach. Accordingly, this paper reports on a multiple case study approach, involving eight organizations from the private and public sectors. The study provides empirical support for capabilities and challenges identified through prior research and identifies additional insights viz. problem-driven approach, time to value, data readiness, data literacy, data misuse, operational agility, and organizational maturity assessment.

Abstract

Inventory control has an important role to maintain the stability of the company's business continuity. With inventory control, companies can meet consumer needs and consumers will feel satisfied if the demand comes on time. On the other hand, with this focus on inventory control, company management must also be careful if the raw material inventory is too large, it will result in high inventory costs, on the other hand, if there is too little raw material inventory, it will result in unfulfilled consumer needs. The purpose of this study is to identify forecasting the amount of sugar demand in 2019 and determine the amount of inventory costs from the forecasting results using EOQ. It is hoped that in the future the company will not only be able to know the future demand side based on forecasting, but the company already has an estimate of the total cost of inventory. The need for sugar raw materials from the forecasting results is 170,173 kg. Where the most needs are in April and November 2019, the number of economic purchases is 5218 kg with a frequency of ordering 33 times a year. Based on company policy, there is currently no information on safety stock and reoder points set by the company. With the EOQ proposal, the results of the safety stock and reoder point are 34,349 kg and 70,875 kg, respectively. The TIC proposal based on the EOQ is able to reduce the total inventory cost which was originally with the company's policy of Rp. 1,805,785,530 to Rp. 1,805,138,304 where this figure saves Rp. 647,226

Abstract

PT. XYZ is a company that produces pharmaceutical products for livestock. Most of the raw materials for veterinary drugs consist of B3 powder (toxic and hazardous materials). Waste from the production process is unavoidable, one of the types of waste produced by PT. XYZ is B3 powder wastes. According to the Environmental Service (DLH) B3 waste cannot be directly discharged into the environment, therefore PT. XYZ uses 3rd party services in processing B3 waste disposal. PT. XYZ produces powdered B3 waste at an average of 267.12 kg/month, the cost that must be incurred by the company to manage B3 waste and the value of loss of raw materials is Rp. 28,094,703.70/year. This study aims to design a system for the minimization of B3 waste by using a Soft System Methodology (SSM) approach. The proposed changes from this research use the 3R principle (reduce, reuse, recycle). The implementation of the proposed changes can result in cost efficiency incurred by the company for B3 waste management of Rp. 18,368,995.87/year.

Abstract

This study identifies the criteria for developing natural tourism potential in Rembang Regency. There are problems, such as on the white sand beach of Wates. There are still attractions that have not been managed, namely the mangroves around the beach that have not been managed and around the tour. There are no lodgings such as hotels and guest houses for tourists, so for now, the distance to the beach can be accessed by vehicle because of quite a distance. To meet the requirements of tourist attraction, five criteria must be met based on the literature study: Attractions, Accommodations, Accessibility, Activities, and Amenities. After obtaining the criteria, a weighting will be carried out for each criterion based on 5A using the AHP approach. Based on the results obtained, it is known that the Accessibility criteria have the highest weight value, followed by the Amenity, Activities, Accommodation and Attractions criteria. Value modelling is carried out to calculate tourism feasibility according to standards.

Abstract

Rembang Regency is not a tourist destination in districts or cities in Central Java because tourist visits to tourist objects in Rembang Regency are still relatively small when compared to other areas around Rembang Regency such as Demak Regency, Kudus Regency, and Semarang Regency. The potential for cultural tourism in Rembang Regency is still relatively small compared to natural and artificial tourism. So that the potential to be taken is the potential for cultural tourism. There are six components of tourism development as the basis for research: Attraction, Amenities, Ancillary Service, Activity, Accessibility, and Accommodation. There are additional tourism development components from interviews with the Culture and Tourism Office of Rembang Regency, namely Environment and Human Resources. So that it can be managed clearly and accurately measured and tourism potential can be said to be feasible, it must first design indicators so that tourism managers can find out what must be developed for cultural tourism potential, so that later it is expected to become a tourist destination that can help the economy in the Regency Rembang. This study uses the SECI method (Socialization, Externalization, Combination, and Internalization). After getting the indicator then, calculate the weight using AHP (Analytical Hierarchy Process)
