Pemanfaatan Sensor Suara sebagai Fitur On/Off Switch pada Engine Starter dan Power Tailgate Kendaraan

Fitur otomotif mengalami perkembangan pesat secara berkelanjutan sebagai dampak perkembangan revolusi industri 4.0, khususnya dalam hal memudahkan pengoperasian fitur sebagai penunjang keselamatan maupun kenyamanan berkendara. Fitur yang dirancang dengan cara mengintegrasikan sensor suara untuk menyalakan dan mematikan engine starter dengan memanfaatkan car starter motor bawaan dari kendaraan itu sendiri. Selain itu ditambahkan juga fitur membuka dan menutup bagasi kendaraan sehingga bisa berfungsi secara otomatis. Operasional on/off switch untuk engine starter dan power tailgate menggunakan media internet eWeLink dan google home sebagai penghubung sensor suara dengan switch dan aktuator power tailgate secara wireless melalui perintah yang telah diprogramkan pada perangkat. Pada penelitian ini berhasil menyalakan atau mematikan engine starter berkisar 1 detik sedangkan untuk membuka dan menutup berkisar 1 menit. Namun, berdasarkan hasil diskusi pada pengujian bahwa waktu untuk membuka atau menutup power tailgate ini masih tergolong lama hal ini disebabkan pada saat eksisting pemilihan spesifikasi motor aktuator yang ada di pasaran belum mendapatkan requirement yang memadai meskipun dari sisi fungsional telah bekerja dengan baik.

Design of non-solenoidal operation of starter motor

A novel design and fabrication of the gear reduction starter motor is proposed. In this proposed configuration, the conventional solenoid of the starter motor is eliminated, resulting in a reduction in the starting current required while cranking, and the weight of starter motor is reduced by making it more compact. Failed/dead cranking and the cost of starter motor are also decreased. The function of the solenoid in the starter motor is replaced with a spring-coupled drive mechanism, which makes the function of the starter motor an automatic process. This replacement will affect the state of charge (SoC) and depth of discharge (DoD) of the battery positively, thereby reducing the battery drain and making it last long.

Rancangbangun Starter Elektrik Portabel untuk Mesin Traktor Tangan

Indonesian farmers used to utilize crank to turn on hand tractor machine till today. It may make operators weariness and potentially raised work accident. The purpose of this study was to design a portable electric starter for hand tractor machine. Moreover, the study was addressed to evaluate the performance of the design. The minimum rotational speed (n) and initial torque (T) in decompression and non decompression conditions were adopted to calculate the minimum power (P) requirement. The minumum power of decompression and non decompression were 572.78 watts (≈ 0.74 hp) and 841.75 watts (≈ 1.09 hp), respectively. These values used as a reference in determining the main components, namely the wet type 12 volt battery and the serial type direct current starter motor. The next step, set up additional components, transmission mechanism, as well as concept of portable electric starter. The design was realized by construction and assembly process. A performance test was carried out on the prototype. The performance test of non decompression showed 1.88 seconds for working time, 264.56 Joules for workload (operator), 363.20 rpm for rotating speed and 0.68 watt hours for power requirement. Overall, application portable electric starter indicated better performance than crank. This study proved a high preference of operator on application of portable electric starter in decompression conditions.

Application of LED (Lean Embedded D3) Methodology to Improve Quality of Starter Motor EGT- Assembly

In the era of liberalization and open global market economy, Each and every organization wants to produce and deliver good quality products at a minimum price in order to remain competitive in the markets .To achieve this objective one must pay proper attention to their quality and lean manufacturing practices and aim for zero defects in their organizations. In the present work a new methodology namely LED3 (Lean embedded D3) methodology is applied to address the quality issue in starter motor manufacturing company. The root cause for failure of starter motor was successfully traced out using Ishikawa and five why analysis and a new technique was implemented to overcome the quality issue. After successfully implementing the new method the rejection rate has come down drastically from 7% to less than1% and Cycle time reduced from 1min to 30 sec. Total 3 hours saved per day
