Abstract

The problem faced by PT Sari Kayu is that fluctuating production demand and high product variance make production inefficient. If the problem does not have a good factory layout, it affects material handling costs, material handling distances, and material handling time. For example, at PT Sari Kayu, there was a delay during a wrong project because the two projects were running simultaneously. The delay is due to the lack of resistance of the production floor to sudden high fluctuations in production demand. In addition, product variance is also a factor in the longer production process due to the different sequence of production processes and less supportive machine layouts. It is hoped that with the proposed layout, PT Sari Kayu will be able to face the fluctuating demand for production.

Abstract

Mom’s Farm adalah sebuah usaha penanaman sayuran organic yang merupakan sebuah program pengabdian masyarakat yang dilakukan dan dinaungi oleh Fakultas Teknik Universitas Katolik Indonesia Atma Jaya dalam bidang penanaman tanaman hidroponik dan urban farming yang bekerja sama dengan Desa Sampora khususnya Kampung Nagrek. Dalam menajalankan roda usaha, mom’s farm mengalami kendala dalam menyalurkan produk kepada konsumen. Pendistribusian hasil panen yang belum jelas dan maksimal akan menyebabkan para petani di Mom’s Farm dirugikan karena kurang efektif dan efisiennya sistem pendistribusian hasil panen sehingga diduga akan mengakibatkan terjadinya kurangnya pendapatan yang diterima petani. Maka dari itu perlu dilakukan pembinaan pemasaran produk lebih lanjut dimana dalam hal ini adalah Pendampingan Pemasaran Mom’s Farm dengan Aplikasi Digital Marketing seperti Grab dan Tokopedia. Diharapkan dengan diberikannya pendampingan mengenai pemasaran produk secara online akan menarik pembeli yang lebih lagi bagi usaha Mom’s Farm. Sehingga selain mendapat konsumen secara offline seperti yang sudah ada, namun juga bisa menjangkau konsumen baru yang lebih luas.

Abstract

SClustering is a commonly system used by the distribution company. Some consumers who are in the same location but located in two different clusters as a result of a fixed and rigid area within cluster, resulting in longer delivery time and higher cost incurred to deliver the order. The purpose of this research is to determine the optimal vehicle route using three-phase method approachthat improve the clustering system. Complexity arising from the problem of this vehicle routing includes variant types of vehicles and variants of product types. The three-phase method includes a cluster-making phase with a maximum distance between consumers within 10 kilometers, a cluster adjustment phase, and a routing phase that determine shipping routes and calculate total distribution cost. Numerical examples shows that the cost of distributing goods can be minimized, from an average of IDR 1,064,408.33 to an average of IDR 775,586.46. Thus a three-phase method may improve the clustering system by reducing distribution time and cost.

Abstract

PT. SKI is a manufacturing company engaged in the production of hair and skin beauty products such as hair masks, shampoos, conditioners and others. Demand for beauty products that are increasing every day requires companies to produce more than inventory. One solution is to expand the production area in an increase large-scale production processes. However, the current production area which cannot optimally support this due to the absence of vacant land or expansion of the area that can be carried out. Based on the results of interviews with the head of the production section, the plan to move locations in several alternative places is the right solution for the company. In the specific task studied, the need for this location transfer will be related to multiple decision making taken by the company. One technique to identify these problems is using the Analytical Hierarchy Process or AHP method where this method is a simplification of complex problems that are not structured, strategic, and dynamic into their parts, and organize in a hierarchy. The level of importance of each criterion that supports decision support is relatively compared to other criteria by considering various considerations and then synthesizing to determine criteria that have high priority and play a role in influencing the results of the system. Based on the results, it is found that there are several criteria which plays an important role in the selection of factory location alternatives obtained in the mathematical equation. The first criterion namely Investment and Operations has a value of around 55.84% indicating that the first best alternative location in the sub criteria is land price, land area, expansion and employee salaries (UMR). Continued around 58.47% in the second general criteria, namely facilities with sub criteria of water, electricity, transportation and service which showed the best selection was in the first location alternative and 73.51% in the criteria for ease of licensing and transportation access at the first alternative location. By comparing the three data multiplication matrices and assessment criteria, it was found that a large comparison of the three general criteria had a total of 60.91% of the first alternatives being the priority of PT. SKI to choose the location of the new factory area, which is located in Padurenan, Gunung Sindur, Bogor, West Java.

Abstract

The government livestock carrier cruise program is a dedicated program to improve the supply chain management of livestock and the ultimate goal is selfsufficiency of beef in 2026. This carrier has one fleet with the capacity of 500 cows and sails through 8 ports regularly. The island of Nusa Tenggara are the local producers for the livestock carrier cruise which is an area of provincial surplus of beef. For the future the government plans to add more ships to the armada from the current one fleet to six fleets of livestock carrier cruises. The current livestock carrier cruise program has not been optimal in shipping cows to the consumer area. This is caused by the limitation of number of fleet and theexisting route that the livestock carrier has to sail through has created some obstacle to maximizing the number of cows to be distributed. This research aims to optimise this carrier cruising route with criteria including having high supplied beef percentage rate and having the most minimum cost. This optimisation problem solved by genetics algorithm methid and develop twodifferent scenarios that suggest alternatives for an optimal route. To make things easier, a computerized program with genetics algorithm method for a livestock carrier cruise optimization network are designed. The outcome of this research is a proposed optimised route on scenario 1 with total cost of Rp 443,306,533.26, and total load of 1,374 cows. As for the future to add five ships, the conditions are met by using the results of the second scenario with total cost of Rp 1,321,505,850.62, total load of 3416 cows and the route network for six ships
