Abstract

Instrument equipment is part of the equipment installed on the tool intended to find out and get the desired data from an activity. One of the important instrument equipment in various fields is the measuring instrument. A jaral measuring instrument is basically a tool to find out how much distance or how long the distance is from an object. The need for measuring instruments used and having high accuracy encourages the creation of more measuring instruments. The purpose of this study is the development of a prototype distance measuring instrument based on Arduino uno microcontroller using ultrasonic sensor HC-SR04. This ultrasonic sensor uses the speed of sound to measure the distance with a magnitude of 340 m/s, thus knowing the time between sending the signal and receiving the signal so that the distance between the transmitter and the receiving object can be calculated. The distance measurement data will then be displayed on a 16 x 2 liquid crystal display for easy reading. This design is controlled through the Arduino Uno R3 kit based on ATMEGA 328 P which is implemented in an acrylic plastic plate as a place for the circuit. The test results from the distance measurement instrument research have a measurement error value range of 0% - 0.067%, so it can be said that the distance measuring instrument from this study has a high accuracy value.

Abstract

AbstrakPT Domus Jaya Lampung merupakan perusahaan yang bergerak dibidang refineri dan fraksinasi minyak kelapa sawit di Lampung Selatan dan merupakan salah satu supplier minyak nabati yang berkualitas untuk kebutuhan ekspor dan lokal. Pada tahap perencanaan pembongkaran tangki terdapat permasalahan, permasalahannya yaitu tidak memungkinkannya penggunaan crane dalam proses pembongkaran tangki. Penyebabnya adalah biaya penyewaan crane yang cukup mahal sehingga mengakibatkan perusahaan akan mengeluarkan biaya yang cukup besar untuk proyek pembongkaran tangki, kemudian penyebab berikutnya yaitu area penempatan tangki yang cukup sempit dan padat oleh saluran perpipaan sehingga crane tidak dapat beroperasi pada area tersebut. Tujuan dari penelitian ini adalah membuat rancang bangun tank erection manual jacks guna memberikan fleksibilitas penggunaan alat dan efisiensi biaya dalam proyek pembongkaran tangki. Metode penilitian meliputi identifikasi masalah, perumusan masalah, identifikasi akar masalah, tindakan korektif dan pemantauan sistem. Hasil penelitian yaitu rancang bangun tank erection manual jacks sebagai alat bantu pengganti crane pada proyek pembongkaran tangki dengan kemampuan beban angkat mencapai 20 Ton dengan fleksibel pada area-area sempit dan dapat menurunkan biaya pengeluaran sebesar 63% pada proyek pembongkaran tangki.

Abstract

Tobacco is the main raw material that is utilized to make smoke. In the process the tobacco must experiences about carve, so that the process is then required carve engine existing chopper machine that uses the engine chopper blades involute results obtained in the chopped tobacco patches that appear black spots when dried so that we modify cutting mechanism carve crankshaft engine driving source motors 5.5 ( PK ) , and has been using the automated system on the conveyor secure in its use . In the selection of assessors and alternative design considerations needed to get the best design that later developed in the direction of making tools. This machine uses the calculation of motor power , the power distribution calculation , calculation , calculation of belt pulley diameter , shaft calculations . This machine has a design dimensions 1200 x 450 x 1050 ( mm ) with the results of chopped tobacco have uniformity chopped 2 , 4 and 6 ( mm )

Abstract

Proses pemotongan rumput di Bandar Udara ABC adalah bagian penting dalam pengelolaan landscape. Penelitian ini bertujuan untuk mengetahui efektivitas mesin yang digunakan untuk pemotongan rumput. Hasil analisis ini dapat menjadi tolak ukur bagi perusahaan untuk meningkatkan kinerja mesin yang ada, menambah mesin, atau mengganti mesin sebagai upaya memaksimalkan produktivitas pengelolaan landscape di Bandar Udara ABC. Dalam studi kasus ini, mesin pemotong rumput yang digunakan terdiri dari 2 Mower Kubota L3800 dan 5 Mesin Brush-cutter Tanaka. Efektivitas mesin diukur dengan menggunakan Overall Equipment Effectiveness (OEE). Masing-masing nilai OEE untuk Mower 1 dan 2 adalah 47.05% dan 42.08%. Sedangkan untuk mesin Brush-cutter 1, 2, 3, 4, dan 5 adalah 43.46%, 43.49%, 46.75%, 48.41%, dan 44.72%. Nilai OEE mesin pemotong rumput ini masih belum memenuhi standar kriteria yang ditetapkan JIPM yaitu 85% untuk efektivitas sangat baik dan 60% untuk batas wajar efektivitas mesin. Sehingga hasil dari penelitian ini dapat digunakan sebagai bahan pertimbangan bagi pengelola bandara dalam melakukan perbaikan maupun perawatan untuk menghindari turunnya produktivitas.

Abstract

The current green concept trend in Indonesia is contributing to the advancement of sustainability across all industries, including the construction materials sector. The concrete business is crucial because it provides the fundamental components for concrete, which is a critical role it performs in the building process. Throughout the production process, ready-mix concrete has a very negative effect on the environment. Planning and constructing a green concept will be 10-20% more expensive than conventional development. Researchers will use the value for money (VfM)-at-risk analysis model technique to cost-effectively apply the concept of the green concrete industry to statistical analysis and case studies. To improve cost performance, this research updates the knowledge on the green concept for concrete industrial objects and searches for factors that affect its application using partial least square (SEM-PLS) analysis and green concept modeling based on the value for monet at risk analysis model. "10 factors that influence the performance of green costs in the concrete industry" were identified by the research, and they include the following: the risk analysis model, the planning stage, internal costs, production, value for money, the bidding stage, the implementation stage, product use, the operation stage, and maintenance. The application of the VfM-at-risk analysis model was able to increase the green cost performance by 8.66% with a return of 9 years and 2 months by gaining benefits as an environmentally friendly and sustainable concrete industry.
