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.

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.

Turbine engine airstarts are conducted throughout the aircraft airspeed/altitude envelope in ground-based simulation test facilities and in flight tests to ensure safe and reliable engine operation. Differences in airstart times are attributable to variations in engine turnaround speed (the engine core speed at which the airstart is initiated in spooldown airstarts); combustor lightoff time; installation effects such as customer bleed and power extraction; starter motor torque; fuel flow scheduling; and engine-to-engine variation and degradation. An analytical approach is presented to account for these differences and adjust engine airstart time for a low-bypass, twin-spool, military, turbofan engine. Two examples are presented illustrating the difference in airstart times and the analytical approach used to adjust the start times.
