Abstract

This research discusses the proposed implementation of lean manufacturing system at PT. MONIER. PT.MONIER is a manufacturing company engaged in the production of tiles with 3 types of product that is Exeltile, Centurion tile and Elabana tile. PT. MONIER is using push system as their production system methodat the moment. Current state value stream mapping is made to see shop floor as a big picture. Calculationshows that current state Process Cycle Efficiency (PCE) is very low with only 4,51%. The company still farfrom “lean” because minimum requirement of a company called lean when the value of PCE more than30%. Meanwhile, current state Overall Equipment Effectiveness (OEE) is 79,98%. From the observation, itcan be found that there are many non-value added activity (waste) at PT. MONIER factory. From theidentification of waste using check sheet and cost calculation resulted by wastes, it was found that inventorywaste post the biggest cost with 92,8% of the total cost of existing waste. With further analyze, it is knownthat the root cause from inventory waste is due to the company allow overproduction and there is wrongphilosophy against inventory. Those root causes which has found before is to be eliminated with leanmanufacturing system approach. There are several methods that will be applied in PT. MONIER such as 5Simplementation and standarized work, then future state value stream mapping is made to see all proposedmethods in a big picture. In addition, this future state condition will be simulated to give a betterperspective. With the implementation of lean manufacturing system, future condition is as same as currentstate value condition. Future state Process Cycle Efficiency (PCE) is 4,51% and future state OverallEquipment Effectiveness (OEE) is 79,98%. This happens because the theory and methods of lean from leanmanufacturing system can only be applied on the assembly line and one piece flow.

Abstract

The purposes of this research is to analyze the optimal distribution system at PT. X. There are three alternatifs given. The method used is saving matrix method and Knapsack using distance and time data. This research is considered the traffic conditions so the distance matrix is transformed into time matrix. The result show the distribution route and sequence of optimal methods. Distribution route is obtained using Farthest Insert, Nearest Insert and Nearest Neighbor. The sequence of methods is placed saving matrix method at first and then Knapsack or vice versa. After this, the distribution cost is calculated for three alternatifs given. This cost calculation is considered pinalty cost which is the value of opportunity cost when truck is not fully used. The results of cost calcutation show, when considered penalty cost, the best alternatif is alternatifs three that deliveries all consumer demand with freight forwarding services. However, this penalty charge is not real value (not spending money) so the company does not consider the cost of this penalty. When calculating cost without penalty cost, the best alternatif is alternatif one that deliveries all consumer demand with the company’s truck. In the first alternatif, the best method is saving matrix distance – knapsack. This method aims to select nearby consumers then optimize the distribution fleet.

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

Ponggang Village is located in Serangpanjang District, Subang Regency, West Java. There is a natural beauty in Ponggang Village that is not yet known by many people, namely Curug Ponggang with its natural beauty and soothing atmosphere. To get to Curug Ponggang, there is only one main road access. However, the problem is that there are no lighting facilities on the road access with a road length of 700 meters and a road width of 1.2 meters so that with slippery and steep road access conditions, high vigilance is needed when crossing this road, especially at night or at night. foggy. Therefore, this study aims to examine the planning for the construction of Solar Street Lighting (PJUTS) on the Ponggang Curug access road to improve the comfort and safety of road users. There are 4 alternative concepts, where one selected alternative provides a total PJUTS budget plan for 15 years. The chosen alternative concept uses a PJU lamp post with one arm using a 50W LED Solar Light Model GW8833 lamp. Based on the research that has been done, it takes as many as 22 light points with each lamp post 33 meters apart and the pole height is 3 meters. It is hoped that the construction of these lamps can improve the quality of effective and efficient lighting in Curug Ponggang

Abstract

Optimization is the search for the optimal value of a problem with the help of one or more objective functions. Optimization problems are often found in everyday life and become important in the operation of a production system. The simplest optimization problem in the industrial world is solved using linear programming. Linear programming equations are made to solve optimization problems in the industrial world. In optimizing a problem, computational tools are needed to produce the optimal solution. Many computational tools are used, one of which is Excel Solver. Excel Solver is operated because many Microsoft Office users have this computing tool. Where everyone commonly uses Excel. The world of industrial Engineering needs someone who can solve optimization problems, especially since the current industrial era is getting more advanced. More skills are necessary for dealing with the Industrial Revolution 4.0 and Society 5.0, and it becomes a mandatory ability for an industrial engineer to solve this problem.

Abstract

UMKM Mulya PS Shop is a business that sells pet food. The problem faced by the Mulya PS Shop owner is that the shop still uses a sales and service system using manual methods, such as using notes. This problem results in an inaccurate number of orders and income results. As well as problems for consumers, where consumers have to come and order directly at the shop. This makes it difficult for consumers or customers who want to order remotely or outside the area. So based on the problems above, it is necessary to design an information system for making an Android-based goods ordering application and provide socialization of the Android-based goods ordering application to help Mulya PS Shop business owners have complete information and an easy and fast transaction system. By socializing the Android-based application information system, it can help accelerate technology transfer to Mulya PS stores. The application that has been created has fulfilled the purpose of service, namely helping MSME owners and customers, in the goods ordering system and transactions. And the socialization activities have been successfully carried out with good results and are very good at conveying the material and objectives. It is hoped that with this service activity, there will be integration between the Community Service Program and the final assignment courses.

Abstract

Permasalahan yang dihadapi oleh PT SEI adalah permintaan produksi yang fluktuatif dan variansi produk yang tinggi membuat produksi tidak efisien jika tidak memiliki tata letak pabrik yang baik karena memengaruhi biaya material handling, jarak material handling, dan waktu material handling. Sebagai contoh, pada PT SEI pernah terdapat delay pada saat salah proyek karena dua proyek tersebut berjalan bersamaan. Hal ini disebabkan ketahanan lantai produksi yang kurang terhadap fluktuasi permintaan produksi yang tiba–tiba tinggi. Selain itu, variansi produk juga menjadi faktor penyebab lebih lamanya proses produksi karena urutan proses produksi yang mungkin berbeda dan tata letak mesin yang kurang mendukung. Diharapkan dengan usulan tata letak PT SEI akan mampu menghadapi permintaan produksi yang fluktuatif. Kegiatan pengabdian kepada masyarakat ini dilaksanakan melalui beberapa tahapan, yaitu pembuatan proposal, pembuatan konten materi, pelaksanaan, dan evaluasi pelaksanaan kegiatan sosialisasi. Adapun pesertanya adalah pimpinan perusahaan dan karyawan bagian operasional. Dari evaluasi kegiatan didapatkan hasil bahwa umpan balik baik dan sangat baik dari setiap kriterianya. Melalui kegiatan sosialisasi ini diharapkan PT SEI dapat memenuhi kebutuhan produksi untuk menghadapi permintaan produksi yang fluktuatif.
