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.

Abstract

Biodiesel fuel is a mixture of diesel oil mixed with vegetable oil (palm). The composition of the mixture affects its properties, especially viscosity and density. The research was conducted to determine the effect of increasing temperature on these properties. By applying several experimental methods, including the ASTM D 445-95 method, the pycnometer method, and the particulate emission test method. The biodiesel test was carried out with variations in temperature of 30oC, 40oC, 50oC, 60oC, and 70oC at room conditions of 24.0oC temperature and 71% humidity. From the temperature variation, the viscosity is 2.23 cSt, 2.61 cSt, 3.1 cSt, 3.7 cSt, and 4.45 cSt. The results of the research prove that the increase in biodiesel temperature affects decreasing viscosity and density which has an impact on reducing particulate emissions.

Abstract

This study examines the relationship between parents economic conditions andstudents learning motivation at MA Darul Ulum Routa, Konawe, SoutheastSulawesi. Using a quantitative approach, data were collected through observation,documentation, and questionnaires. The results showed that most parents havelower to middle economic conditions (average score of 70.57 on a scale of 84),which is influenced by the level of education and the type of work that is generallyinformal. Nevertheless, most parents still support their childrens education. Ingeneral, students learning motivation is classified as moderate to high (average67.54 on a scale of 80), indicating quite good enthusiasm for learning, althoughsome students showed low motivation. Simple linear regression analysis showed asignificant effect (p=0.000) between parents economic conditions and learningmotivation (R²=0.645). This means that around 64.5% of the variation in learningmotivation can be explained by parents economic conditions, while the rest(35.5%) is influenced by other factors, including the learning environment, the roleof teachers, and students psychological factors. In conclusion, the economicconditions of the parents of students at MA Darul Ulum Routa are mostly middle tolower, while the students learning motivation is classified as medium-high. Theanalysis shows a significant positive correlation (64.5%) between the parentseconomy and learning motivation. However, factors outside the economy also playa crucial role. Further research needs to explore these factors for a morecomprehensive understanding.

Abstract

The proofing process is an essential step in bread-making, where the dough is allowed to rest for the gas content to develop and form a soft structure. However, many small-scale bread producers still rely on manual methods for proofing, leading to unstable temperature and humidity levels and longer production times. This study focuses on developing an electrical system for a bread proofer that can stabilize temperature and humidity during the proofing process. The system includes an Arduino Mega microcontroller with a DHT22 sensor for real-time temperature and humidity detection, an I2C LCD for monitoring, and a potentiometer for setting the desired temperature and humidity values. To achieve stability, a PID control system is used. The results show that the system can stabilize at a temperature of 40.10oC and humidity at 80-90RH for approximately 38.4 minutes. This electrical system offers an effective solution for optimizing the proofing process in bread production.
