Abstract

PT. Inti Pantja Press Industri merupakan produsen komponen-komponen bodi mobil Daihatsu merk Xenia, Terios, Ayla, Sirion dan Sigra berlokasi di Bekasi. Industri otomotif memiliki potensi bisnis yang positif karena permintaan mobil yang terus bertambah setiap waktu. Namun, agar dapat memenangkan kompetisi bisnis yang saat ini semakin berat, maka PT. IPPI harus dapat menjalankan produksi secara lebih efisien. Hasil observasi awal pada proses produksi Daihatsu Xenia terindikasi beberapa masalah yang terkait dengan adanya pemborosan (waste) misalnya bottleneck dan cacat. Berdasarkan permasalahan yang terjadi, pendekatan lean manufacturing dipergunakan untuk menyelesaikan permasalahan tersebut. Pertama-tama pemborosan diidentifikasi dengan Value Stream Mapping kemudian Borda Count Method dipergunakan untuk menentukan pemborosan (waste) kritis pada lantai produksi yang hasilnya yaitu waste waiting, defects dan over production yang menyebabkan terjadinya over inventory finish part. Metode 5 Whys kemudian dipergunakan untuk mencari akar penyebab pemborosan (waste). Berdasarkan Failure Mode and Effect Analysis diketahui akar penyebab waste tertinggi adalah operator tidak membersihkan dies sebelum proses press, lifetime komponen yang telah habis namun tidak diganti dan karat pada produk finish part. Rekomendasi perbaikan yang dapat diusulkan yaitu penerapan metode Poka Yoke dengan instalasi sensor dan peralatan di mesin press dan pemasangan wrapping pada pallet produk finish part.

Abstract

Packaging is one of the important aspects of a product’s identity. The good and adorable packaging can increase product competitiveness because it gives a perception to the customers of good quality products. Therefore, a good packaging display is necessary so that packaging quality inspection is very important. Automated defect detection can help to reduce human error in the inspection process. Convolutional Neural Network (CNN) is an approach that can be used to detect and classify a packaging condition. This paper presents an experiment that compares 5 network models, i.e. ShuffleNet, GoogLeNet, ResNet18, ResNet50, and Resnet101, each network given the same parameters. The dataset is an image of cans packaging which is divided into 3 classifications, No Defect, Minor Defect, and Major Defect. The experimental result shows that network architecture models of ResNet50 and ResNet101 provided the best result for cans defect classification than the other network models, with 95,56% for testing accuracy. The five models have the testing accuracy above 90%, so it can be concluded that all network models are ideal for detecting the packaging defect and defect classification for the cans product.

Abstract

The availability of LPG in the community is a sensitive issue. If there is a shortage, it has the potential to cause chaos and inflation. The final consumers, namely households and micro business stalls, will generally be disloyal. They are not tied to one particular store to get the LPG they need. Since the number of tanks in circulation will remain constant, the analysis of LPG availability can be focused on the number of tanks. Continuous simulation method with system dynamics is generally used in system growth analysis. In this paper the method is utilized to model the discrete movement of tanks circulating in the community which in this case is represented in a much smaller system, consisting of filling stations, agents, and stores. The modeling results provide a sufficient picture of how the availability of the tank can be optimized appropriately.

Abstract

The proposed mathematical model aims to optimize the amount of demand based on the uncertainty of salt supply to meet the needs of salt in society. This study uses an econometric approach to model the supply and demand for salt based on the uncertainty of the amount of supply. The research results are the salt productivity model used to build a salt availability model. Meanwhile, the salt demand model is built based on past data about the number of requests for each period. The demand and supply functions for salt use a two-variable linear equation system. The salt field productivity models follow a quadratic polynomial pattern according to the difference in seasons at each time. The demand and supply of salt model follows a linear regression. The supply of salt in Indonesia is uncertain at any time. But, the demand for salt increased at the time. It is necessary to model the demand and supply of salt to meet the demand for salt

Abstract

Chicken slaughter process waste is divided into two types, solid waste and liquid waste. Almost all of the waste generated by the chicken slaughter process can be reused. Lately, Vocational High School in Pasuruan, East Java, has Livestock Agribusiness unit that made a waste treatment program to deal with the problem of waste from the surrounding chicken slaughter process. However, some chicken slaughter process waste cannot be reprocessed and is directly dumped into the sewer due to limited technology. The type of waste that cannot reprocess is blood and chicken feather waste. This research aims to process the waste into high-quality fish food by applying the principle of automation and integrating machines with existing chicken cutting machines. The application of this appropriate technology begins with observing the existing conditions and the process of designing, manufacturing, and testing equipment carried out at Vocational High School in Pasuruan. The research resulted in designing and manufacturing machines that support waste treatment of blood and chicken feathers from Livestock Agribusiness. The machine design consists of three main components: a blood and chicken feather grinder, a vertical mixer, and a fish feed press machine. The expectations of this machine design will support productivity and concern for waste management, which can also build environmentally friendly standards in the Livestock Agribusiness unit of Vocational School in Pasuruan.
