Abstract

In the automotive world, power reduction in long-used motorcycles is a common issue that can affect vehicle performance. Over time, engine components experience wear and decreased efficiency, leading to reduced power output. One solution to address this problem is optimizing ignition settings by upgrading the CDI (Capacitor Discharge Ignition) and replacing the standard coil with an aftermarket coil. Upgrading the CDI and replacing the standard coil with an aftermarket one aim to improve engine power, as the standard CDI has a relatively low output and the standard coil has a limited output capacity. Therefore, the coil must match the output capacity of the upgraded CDI. This study aims to enhance the performance of a 110cc four-stroke engine. The study method used is a quantitative experimental approach, and data processing is carried out using two-way ANOVA analysis of the test results, processed in Microsoft Excel, with the average results taken from three trials per variation. The independent variables in this study are the racing coil with a voltage greater than the standard (up to 90 kV) and ignition timing mapping with a programmable CDI, while the dependent variable is power. The results of the study show that the ignition timing set at 13 degrees and the use of the BRT coil provided the highest power output, reaching 8.33 horsepower at 8000 rpm. This outcome is due to the critical role of ignition timing in controlling fuel combustion in the combustion chamber, where an earlier explosion with a larger spark results in higher power output

Abstract

The movement and stability of a quadcopter is very dependent on the speed of the propellers which are controlled by the BLDC motor. Each propeller produces thrust and torque that is regulated to rotate clockwise (CW) and counter clockwise (CCW). It is important to maintain the balance of the quadcopter, flying electric vehicles such as quadcopters face challenges in the control system, especially in the BLDC motor. Therefore, the program configuration on the quadcopter controller is very important so that the quadcopter can fly stably as desired by controlling the rotation of the BLDC motor and utilizing sensors to support flight stability. DJI NAZA M V2 is a good flight controller in the quadcopter category, mainly because of its advanced control algorithm and stability features. This advantage allows users to have a stable and safe flight even in unfavorable weather conditions. The application of BLDC motor control program configuration to flying electric vehicles, especially quadcopters, shows that the configuration of the flight controller and electronic speed control has a significant impact on overall performance. Configuration includes basic settings such as mixer type, battery, throttle, reverse, timing degree, brake, power, and helicopter mode. The right combination of settings can make the quadcopter operate optimally and stably in various conditions.

Abstract

The installation and training of CCTV security systems at Pondok Pesantren Putra Baitul Qur'an Al-Khusyu Malang aimed to improve both security and the technical skills of students. The training covered the basics of CCTV technology, including installation methods, system components, and maintenance procedures, enhancing students' knowledge and preparing them for the job market. The hands-on approach proved effective, as participants were actively involved in the installation and configuration of CCTV systems. Before the training, only a small percentage of students were familiar with CCTV technology, but post-training assessments showed a significant increase in knowledge. This program not only contributed to a safer environment within the pesantren but also provided valuable technical skills that students could use in their careers or entrepreneurship. Despite challenges such as limited resources and infrastructure, the training successfully empowered the students with skills relevant to modern security needs. This initiative sets a model for other educational institutions to integrate technical training with religious education, fostering a more skilled and competitive generation

Abstract

The COVID-19 pandemic has had a significant impact on Indonesia's economy, with reduced purchasing power and job losses, highlighting the need for the strategic role of Micro, Small, and Medium Enterprises (MSMEs) in economic recovery. In Mulyoagung Village, East Java, cassava cracker MSMEs face challenges in increasing production capacity due to traditional drying methods that depend on sunlight, which is unreliable during the rainy season. This study proposes the adoption of a drying oven technology as a solution to enhance production efficiency and capacity. By implementing this technology, the production of cassava crackers increased from 200 kg/day to 500 kg/day, a 2.5-fold improvement. Additionally, the study addresses the administrative issues within MSMEs, specifically the lack of structured financial record-keeping. Through training in financial management and the use of break-even point (BEP) analysis, MSMEs were able to improve their financial tracking and decision-making processes. The combination of technological improvement and better administrative practices not only boosted production but also improved the competitiveness of the MSMEs in local and regional markets. This project demonstrates the importance of applying appropriate technology and effective management to overcome operational challenges and foster long-term business sustainability.
