Abstract

A braking system in a vehicle has a very important role in maintaining the safety of drivers and passengers, and preventing accidents. The brake system functions to reduce speed (slow down) and stop the vehicle. A good braking system provides safety and comfort for the drivers. Therefore, it is necessary to design the right braking system for “Sakera” car. In this study, an analysis and calculation of the braking system was carried out to determine the required braking force at a speed of 50 km/hour and other speeds in a distance of 15 m. The data taken in this study was the specification of the braking system used in the Sakera car. The braking system analysis was carried out on flat roads with varying speeds, namely 30 km/h, 35 km/h, 40 km/h, 45 km/h, and 50 km/h with a distance of 15 m for braking. The conclusions of the analysis were obtained, namely the greater the speed of Sakera's car, the greater the braking force to stop the car, the hydraulic pressure on the hose, and the force of the driver's feet, as well as the braking force needed on road conditions with a slope angle of 20º, which is 839.362 N.

Abstract

Ships are a reliable means of transportation in an archipelagic country like Indonesia. The high use of fossil fuels in sea transportation is one of the contributors to emissions that needs attention apart from their dwindling availability. Efforts to use sails as an additional propulsion force on ships are one of the green technology issues in shipping for reducing the use of fossil fuels. It is about how the design affects the thrust on the ship. Tests were carried out on models M1, M2, and M3 in variations 0°, 30°, and 45° wind angles in computational fluid dynamic simulation at 12 knots constant speed. Through this article, there will be a discourse related to optimizing the design of the sail to produce energy efficiency and reduce the use of fossil fuels on ships. The shaped M3 makes greater thrust on the ships than the other two models. The tendency of a decrease in the thrust of the sails with an increase in the wind direction angle, the distribution of force in two directions, namely as normal and parallel to the sails, is suspected as the cause.

Abstract

Pupuk organik merupakan bahan yang berasal dari sisa-sisa tanaman dan hewan, seperti pupuk kandang, kompos, pupuk hijau, jerami, dan bahan lain yang dapat berperan memperbaiki sifat fisik, kimia dan biologi tanah. Bahan organik tidak dapat menggantikan peran dari pupuk anorganik sebagai pemasok hara, karena kandungan unsur hara dalam bahan organik relatif rendah, namun demikian bahan organik dapat meningkatkan efisiensi penggunaan pupuk anorganik. Selain dapat menyelesaikan permasalahan pemenuhan kebutuhan pupuk pemanfaatan pupuk organik dapat mengatasi limbah peternakan yang dihasilkan berupa feses ternak, urine, dan sisa makanan ternak. Pemanfaatan limbah kotoran ternak dapat dikelola dengan melakukan proses fermentasi dengan bakteri EM4. Desa Carang Wulung Kecamatan Wonosalam adalah salah satu desa yang mengalami permasalahan tersebut, di mana desa tersebut memiliki potensi melimpahnya kotoran ternak yang dihasilkan dari kotoran peternak sapi perah, peternak kambing etawa dan peternak kelinci. Dengan kondisi yang demikian peneliti mempunyai rencana melakukan penelitian dengan memanfaatkan bakteri EM 4 untuk mempercepat proses fermentasi komposisi campuran material pupuk organik dengan tingkat keberhasilan 90 %.

Abstract

enanggapi kemajuan pengetahuan otomotif yang semakin meningkat dan meningkatnya rasa ketidakpuasan terhadap peningkatan performa sepeda motor diatas standar. Pengendara sepeda motor biasanya memodifikasi sepedanya untuk meningkatkan performa. Penelitian ini bertujuan mengetahui pengaruh re-mapping ECU (Engine Control Unit) terhadap performa dengan memajukan ignition timing sebesar 0.5°, 1°, 1.5°, 2°, 2.5°, 3° pada putaran 1500 – 9500 RPM dan emisi gas buangnya. ECU yang digunakan ECU standar pabrik kemudian dilakukan re-mapping pada ignition timing. Hasil pengujian didapatkan torsi dan daya terbaik sepeda motor Scoopy dengan memajukan ignition timing sebesar 1° dengan hasil daya 7,4 HP pada 7000 RPM meningkat 0,4 HP, torsi 10,45 N.m pada 4500 RPM meningkat 0,77 N.m. Dimana Scoopy 110 dengan ECU standar memiliki daya 7,0 HP pada 7000 RPM, torsi 9,68 N.m pada 4500 RPM. Fuel consumption terbaik dengan memajukan ignition timing sebesar 3° senilai 0,297 (kg/h). Spesific fuel consumption terbaik dengan memajukan ignition timing sebesar 3° senilai 0,413 (kg/HP.h). Efisiensi termal terbaik dengan memajukan ignition timing sebesar 3° senilai 1,471%. Emisi gas buang terendah dengan memajukan ignition timing sebesar 3° senilai CO 0,34% dan HC 127 PPM.

Abstract

Knowledge and preparedness in facing natural disasters is very important, especially for students who are in disaster-prone areas such as the coastal area of ​​Kenjeran, Surabaya. Based on interviews with the principal and teachers at SD Muhammadiyah 9 Surabaya, it is known that the low understanding of students and teachers about disaster mitigation triggers feelings of anxiety and fear about potential disasters that could occur at any time. To overcome this problem, this research implemented Virtual Reality (VR) technology as a medium for disaster mitigation education at SD Muhammadiyah 9 Kenjeran. VR technology was chosen because of its ability to provide a simulation experience that is close to real situations, so it is hoped that it can increase students' and teachers' understanding and resilience in facing crises. This service aims to provide counseling and outreach to teachers and students with VR learning media at SD Muhammadiyah 9 Kenjeran Surabaya. The approach to solving partner problems is to focus on students' understanding of disaster mitigation with VR-based education and the impact of post-disaster psychological problems. The research results show an increase in students' understanding of disaster mitigation measures, as well as an increase in self-confidence in facing disaster threats after implementing VR. Another positive impact is a reduction in students' anxiety and fear levels, which shows that VR-based simulations are effective in preparing students to face emergency situations. The conclusion is that the use of VR technology as a medium for disaster mitigation education can be an effective alternative for increasing students' readiness in facing disasters in coastal areas.
