Abstract

Dalam menganalisa kegagalan suatu produk, telah banyak diperkenalkan metoda dalam menentukan penyebab kegagalannya. Dari beberapa analisa tersebut, diambil salah satu yaitu metode 8 langkah analisa kegagalan yang dipakai oleh PT. Trakindo Utama Jakarta dalam menganalisa kegagalan produk alat berat dengan merk Caterpillar. Dalam artikel ini akan diuraikan teoritikal 8 langkah analisa kegagalan, pengetahuan dasar yang menunjang analisis, contoh kasus, dan penerapannya. Metoda yang digunakan adalah studi kasus yang akan menjelaskan setiap langkahnya menggunakan kasus nyata yang terjadi di lapangan. Satu kasus yang diambil sebagai contoh adalah kerusakan yang terjadi pada engine OHT 793 CAT dengan hasil analisisnya yaitu faktor penyebab kegagalan yang paling mungkin adalah jenis piston cooling jet yang salah. Adanya kesalahan ini menyebabkan pelumasan pada piston tidak sempurna dan pada akhirnya rusak.

Abstract

This article is motivated by the issue of ineffective handling of organic waste that causes negative impacts on the environment, including air, water, and soil pollution. However, many people do not realize that organic waste has considerable potential to be used as useful and have added value with proper processing, for example such as processing organic waste as material for making compost.This article focuses on the design and estimation of organic waste shredding machines, which are an important tool for processing organic waste into smaller particles. This organic waste shredding machine has a primary function, namely as a tool to accelerate the process of shredding organic waste into smaller particles. The project begins by identifying needs, including determining the desired processing capacity, the type of organic waste to be chopped, material selection, component size and shredding particle size. Then a conceptual design is made that includes important aspects such as the manufacture of the frame and engine body, shafts and bearings, blade components, transmission systems. Computer-based design software (CAD) is used to create 2-dimensional and 3-dimensional models of organic waste shredding machine, thus enabling visualization and refinement of the design. Cost and time estimation are an important part of this project. The estimation includes factors such as material costs and also assembly fabrication costs. Time estimation describes the stages in the design process, as well as the production process of the organic waste shredding machine itself. The estimation includes factors such as material costs and also assembly fabrication costs. Time estimation describes the stages in the design process, as well as the production process of the organic waste shredding machine itself.The design and estimation process of this organic waste shredding machine produces a model of a organic waste shredding machine with a processing capacity of 1 kg, using the method of shredding blades shaped like propellers with a total of 24 blades, each of which has 3 blades. And there is a filter so that the shredding results have a size that is relevant to the size of compost in general, this organic waste enumeration process is supported by using an engine-powered gasoline engine with 5.6 HP that is transmitted to the shaft and a shredding blade through the pulley and v-belt transmission.

Abstract

Peranan yang sangat penting dalam budidaya ikan yaitu pemberian pakan. Kegiatan tersebut penting karena pertumbuhan serta perkembangan ikan sangat tergantung pada pakan yang diberikan, pemberian pakan dalam jumlah yang seimbang merupakan hal yang penting untuk keberhasilan suatu budidaya ikan. Pemberian pakan yang terjadi di peternak atau pemelihara ikan yaitu tidak terjadwalnya pemberian pakan serta jumlah pakan yang diberikan yang seringkali terlalu banyak sehingga hal tersebut akan menyebabkan pemborosan material dan dapat mempengaruhi kualitas air sehingga dapat mengganggu kelangsungan hidup ikan yang dibudidayakan. Oleh karena itu pengembangan dan perancangan alat pemberi pakan ikan otomatis berbasis IoT akan diperlukan. Dimana alat tersebut dapat dioperasikan dimanapun dan kapanpun hanya menggunakan smartphone yang terkoneksi ke internet. Perancangan dan perangkaian kelistrikan pada mesin pemberi pakan ikan otomatis sangatlah penting untuk mengalirkan arus listrik yang bertujuan pada motor listrik dimana arus tersebut dialirkan oleh sebuah komponen agar bisa diatur penggunaan arus listrik yang diperlukan dengan hasil pengujian mesin ini membutuhkan daya saat standby sebesar 12 Watt dan daya saat running sebesar 150 Watt atau memerlukan konsumsi energi sebesar 10,71 kWh dalam 30 hari.

Abstract

The increasing need for efficiency and productivity in the Indonesian heavy equipment sector requires technological innovation to improve performance and reduce operational costs. This article aims to develop and implement Artificial Intelligence (AI) technology in heavy equipment in Indonesia, so that it can improve efficiency and productivity. By using an AI system development approach consisting of several stages, namely data collection, model development, testing, and implementation and also conducting needs analysis and identification of the potential for implementing AI technology in heavy equipment in Indonesia. The results show that AI technology can improve the efficiency and productivity of heavy equipment in Indonesia by reducing operational time and maintenance costs. In addition, AI technology can also improve work safety and reduce the risk of accidents. The conclusion obtained is that AI technology innovation can be an effective solution to improve efficiency and productivity in the Indonesian heavy equipment sector. Therefore, it recommends the application of AI technology to heavy equipment in Indonesia to improve performance and reduce operational costs.

Abstract

Based on the fact findings in the field, the author found a problem that occurred in the Caterpillar 390F Excavator Stick Cylinder where it was damaged, this damage can be coused by many factors that are suspected to be the cause of the damage that occurred to the stick cylinder. Alleged causes of damage to the stick cylinder include contaminants in hydraulic oil, infrequent maintenance and excessive loads. To find out the main cause of damage that occurs to the stick cylinder, an analysis is carried out using the AFA method which refers to field facts, visuals, and literature studies. Through the analysis process, the possibility of damage was found, namely internal leakage in the stick cylinder, damage to the piston ring and seal, bending of the rod cylinder. Damage to the stick cylinder is caused by damage to the ring (173-3414), ring (155-9157) and seal as (8C-9182) which then causes stick cylinder drift. After analysis, the possibility of part damage is caused by dieseling. Dieseling is caused by air and other gas content that is saturated mixed with oil vapours from hydraulic oil. Its Prevention by removing all air content and flammable gases in the cylinder before use. Move of the cylinder several times up and down, to push the air back into the tank before use.
