Abstract

Pada saat ini kendaraan roda empat memiliki sistem pengapian dengan distributor dan tanpadistributor/distributorless. Saat ini terjadi kecenderungan untuk meniadakan sistem distributor(distributorless) pada sistem pengapiannya. Hal ini dikarenakan pada sistem pengapiankonvensional memiliki banyak kelemahan diantaranya kerusakan pada platina, keausan padamoving parts. Dalam aplikasinya, kendaraan roda empat juga ada menggunakan sistemdistributorless.. Sistem ini lebih mampu secara tepat memenuhi timing ignition pada berbagaikecepatan untuk memperoleh proses pembakaran yang sempurna. Berdasarkan kelemahansistem distributor, maka dalam penelitian ini dirancang sistem open loop distributorless digitalmultipurpose yang diharapkan mampu meningkatkan kualitas pembakaran. Untuk mengetahuiunjuk kerja sistem distributor dan sistem OLDDM maka dilakukan pengujian dan kemudiandibandingkan antara distributor dan OLDDM. Hasil pengujian menunjukkan bahwa sistemOLDDM lebih unggul daripada sistem distributor, tegangan dan arus baik primer maupunsekunder yang dihasikan mampu stabil pada putaran rendah maupun tinggi, dimana nilainyasebesar 11.9 V dan 21.5 kV serta 1.9 A dan 4.8 A .Kata kunci: Distributorless, tegangan dan pengapianRecently there are two methods of ignition system for a four-wheeled vehicle that is thedistributor and without distributor (distributorless). In nowadays there is a tendency to replacethe distributor system in the ignition system. This is because the conventional ignition systemhas many disadvantages including damage to the contactor part, wear and tear on movingparts. In its application, there is also a four-wheel drive system uses distributorless . Thissystem is able to precisely meet the ignition timing at various speeds to obtain a perfectcombustion process. Based on the weakness of distributor system, so in this study open-loopsystem designed multipurpose digital distributorless (OLDDM) is expected to improve thequality of combustion. To determine system performance and system distributor OLDDM thenwas tested and then compared between the distributor and OLDD M. The results show that theOLDDM is superior than distributor system. The result of voltage and current both primary andsecondary is stable at low and high rotation, where the value are 11.9 V and 21.5 kV and 1.9 Aand 4.8 A.Keywords: Distributorless, voltage and ignition

Abstract

Di indonesia banyak penduduk yang berprofesi sebagai peternak. Jika peternak yang memilikijumlah ternak banyak (lebih dari 5) akan mencacah rumput gajah dengan cara manual, itu akanmenghabiskan waktu, jadi dengan adanya alat pencacah rumput gajah akan sangat membantumenghemat waktu. Alat pencacah rumput gajah adalah alat yang dapat membantu menghematwaktu. Jadi alat pencacah rumput gajah adalah teknologi tepat guna. Proses untuk membuatalat pencacah rumput gajah adalah dengan melakukan perhitungan poros dan pasak, dayayang dibutuhkan alat pencacah rumput gajah, kapasitas produksi pada alat pencacah rumputgajah. Dari proses perhitungan alat pencacah rumput gajah di dapatkan daya motor sebesar0,64164 Hp dengan putaran 707,5 rpm, diameter poros sebesar 2,39 cm dengan bahan S45C,dan proses produksi didapatkan 1352 kg/jam.Kata kunci : Poros, daya, rumput gajah, mesin, ternakIn Indonesia many people who work as breeder. If the breeder will cut elephant grass by hand,it will spend the time, so with the bulrush enumerator tool will greatly help save time. Bulrushenumerator tool is a tool that can help save time. So apparatus bulrush enumerator isappropriate technology. The process to make the bulrush enumerator tool is to performcalculations and peg shaft, power tools required enumerators of bulrush, the productioncapacity of the apparatus bulrush enumerator. Of the calculation tool in bulrush chopper getmotor power of 0.64164 Hp to 707.5 rpm rotation, shaft diameter of 2.39 cm with a material S45 C , and the process of production obtained in 1352 kg / hour.Keywords: Axle, power, elephant grass, machinery, livestock

Abstract

Abstrak:Pakan ternak memegang peranan yang sangat penting dalam usaha peternakan karena harus mempunyai nilai giziyang tinggi.Pada Usaha Kecil Menengah (UKM) pembuatan pakan ternak di Kecamatan Jatirejo Kabupaten Mojokertoini dalam proses produksinya sudah menggunakan mesin, tetapi hasil bonggol jagung yang dihancurkan dari mesintersebut masih jauh dari sempurna. Oleh karena itu untuk mengatasi masalah ini adalah dengan merancang alatpenghancur bonggol jagung. Dengan menggunakan tujuh pisau penghancur dan desain peletakan pisau dibentukspiral. Material pisau penghancur yang digunakan yaitu Stainless Steeel Food Grade 304. Kemudian merencanakanporos, pasak, dan melakukan analisa dengan menggunakan software Ansys 12.1. Hasil dari perhitungan dan analisa,didapatkan daya yang dibutuhkan menghancurkanb onggol jagung untuk satu pisau yaitu 0,826 HP. Hasil analisa pisaumemiliki tegangan maksimum sebesar 5,408x105 N/m².Kata kunci: Bonggol jagung, baja tahan karat, AnsysAbstract:Animal feed plays a very important in the farm because it must have a high nutritional value. On Small and MediumEnterprises (SMEs) in the manufacture of animal feed Jatirejo District of Mojokerto regency is in the process ofproduction has been using the machine, but the results were crushed corncobs of these machines are still far fromperfect. Therefore, to overcome this problem is to design crusher corncobs. By using the seven-blade knife layingcrusher and formed spiral design. Materials used are knives crushers Food Grade Stainless steeel shaft 304. Thendesigning the shaft, pegs, and performs analysis using ANSYS 12.1 software. The results of calculation and analysisshowed the power needed to destroy corncob one knife is 0,826HP.

Abstract

Lombok has high tourism potential that requires a reliable electricity supply, one of which comes from the Lombok FTP-2 2Å~50 MW Power Plant in Sambelia, East Lombok. This power plant uses coal supplied through a Coal Handling system, with Belt Conveyor BC-7 as one of its main components. This study aims to redesign the BC-7 Belt Conveyor with a capacity of 150 TPH through manual calculations of capacity and motor power and using Helix Delta T-6 Conveyor Design software. The study focuses on one conveyor unit, using coal material, and only discusses aspects of capacity and motor power under stable operating conditions. The methods used include literature studies, field observations, and data collection from the Lombok FTP-2 PLTU. The data was then processed for manual calculations and software simulations. The results showed a transport capacity of 165 tons/hour (a 10% increase from the previous capacity). The highest motor power without SF from the software was 8.49 kW (19.75% greater than the manual result). The use of software proved to be more efficient and helpful in planning belt conveyor systems.

Abstract

The Rice planting process by “Kelompok Tani” in the Tulungagung, East Java is done manually, Manual planting requires a lot of manpower and very costly because the Landowner need to pay to the laborers to plant their Rice Paddy yet requires a lot of time to do the work until done completely and drains a lot of works and efforts. From that, the Rice planter is designed to reduce the planting process. The design concept adopted the “Jajar Legowo” Rice Planting method, with the distance arrangement applied from the Gears comparison so as to produce equal and uniform distances. This manpowered machine is expected to help The Farmers to shorten the planting process without incurring additional costs for Fuel. From the results of the planning and calculation produced a machine with capability of planting rice 26.4m2/ hour using number 40 of chain, sprocket size 242.80mm and Ratio of each sprockets are 1: 4 to produce a uniform planting. Using a 400mm long shaft for the planter and 10mm diameter with ST37 material. On wheels use Bearing with 30mm Bore.
