Abstract

Mesin diesel merupakan salah satu jenis mesin pembakaran internal yang sangat diperlukan dalam kehidupan manusia saat ini. Teknologi mesin diesel terus berkembang hingga saat ini. Namun mesin diesel sangat bergantung pada bahan bakar diesel fosil, sedangkan stok bahan bakar fosil semakin berkurang. Berkaitan dengan fenomena tersebut, maka dilakukan penelitian dengan tujuan mengaplikasikan heat recovery jacket cooler berbasis fuel heater dan menganalisis besarnya konsumsi bahan bakar. Penelitian ini menggunakan metodeeksperimental antara lain pembuatan instalasi fuel heater dan pengukuran konsumsi bahan bakar. Pada percobaan menggunakan bahan bakar biodiesel (B20) dengan variasi temperatur 30oC, 35oC, 40oC, 45oC, dan 50oC. Mesin diesel yang digunakan dalam penelitian ini adalah mesin 4 langkah, 4 silinder, 1500 rpm 18 kVA dan mesin diesel dalam kondisi tanpa beban. Hasil penelitian menunjukkan bahwa semakin tinggi temperatur bahan bakar semakin menurun konsumsinya, sehingga dapat disimpulkan bahwa pemanasan bahan bakar mempengaruhi efisiensi konsumsi bahan bakar.Kata kunci: Mesin Diesel; Konsumsi bahan bakar; Pemanas; Pendinginan Jaket;

Abstract

The use of fuel oil to generate heat or power in the industrial world is still a major concern for researchers. Fuel quality, performance, emissions, and economic factors are some of the parameters that need to be considered for various types of fuel. In Indonesia, there are several types of diesel fuel including Pertamina Dex, Dexlite and Biosolar (B30). Of course, these fuels have different characteristics. To be able to know the character of the fuel, it is necessary to test the fuel on a diesel engine. In this study, an experiment was carried out using this fuel in a Jianfa brand diesel engine with a power of 7 HP type R175A without load with various variations of rpm, namely 1000, 1200, 1400, 1600, 1800, 2000, 2200. The experiment applies to three types of fuel, namely Biosolar (B30), Pertamina Dex, and Dexlite. Consumption is measured in units of time (seconds) per 50 milliliters. From the experiments it was found that Biosolar (B30) occupies the lowest position as evidenced by the duration of time to spend 50 milliliter at 2000 rpm only takes 49 seconds, Dexlite 63 seconds while Pertamina Dex 70 seconds. So it can be concluded that Pertamina Dex is the most economical compared to Dexlite and Biosolar (B30).

Abstract

In the midst of the issue of limited natural resources, technological developments and industry, fishermen, especially Krueng Aceh fishermen who use the light fishing system at night to catch fish, have problems because they still use fuel to operate a portable electric generator.Researchers will conduct applied research on alternative electric generators using batteries and utilizing the Flywheel effect, with 48 Volt battery power, against a 36 volt BLDC electric motor and a capacity of 350 watts. This energy source from the battery will be used as the main source.The purpose of this research is to test the performance of an alternative electric generator powered by battery and flywheel without load and using a load (100,200 and 300 Watt AC electric lamps). The method that will be used is a direct test experiment with a light fishing system on a 3 GT fishing vessel Krueng Aceh.The results obtained from testing the performance of a generator without a load using a 37 kg flywheel, 42 cm diameter, 5 cm thick, and a battery voltage of 48 volts with a capacity of 20 Ah, capable of producing an AC output current with a voltage of 220 volts, 1500 RPM rotation, a frequency of 50 Hz. no burden. For testing with a light bulb load of 100 watts, the alternator RPM is 1500, the voltage is 210 Volts. As for the 200 watt load, the 1400 RPM voltage drops to 200 and the 300 Watt load RPM alternator 1200, the voltage is 110 volts.Keywords: Alternator, Battery, Battery Case, Electric Motor Flywheel.

Abstract

Diesel engines are machines that are very necessary in the industrial world, both manufacturing and transportation. How important is the existence of this diesel engine that it needs to be maintained properly to maintain its performance. With the development of diesel fuel variants, it is necessary to conduct research regarding the phenomena produced by burning biodiesel, especially the B35 type which is widely consumed in the industrial world. The aim of this research is to determine the performance of diesel engines, are specific fuel oil consumption and thermal efficiency produced by diesel engines using B35. The experimental method was applied by varying the load of 0.35 kW, 0.7 kW, 1.05 kW, 1.4 kW and 1.75 kW on an engine speed of 1500 RPM. The results show that the highest specific fuel oil consumption is at a load of 0.35 kW, that is 1361 mg/kWh, while the highest thermal efficiency at a load of 1.75 kW reaches 17.25%.

Abstract

Starting from academic anxiety about the phenomenon of phenomena that occur in the world of education. Quoted from page suara.com there was a 13-year-old student who committed suicide using a towel after doing homework (homework) with his mother, it was known that previously the child complained a lot to his parents because there was too much homework (homework) that stressed him.The aim of this research is to describe academic factors in Muhammadiyah high schools, describe the symptoms of academic stress among Muhammadiyah high school students, describe various types of academic stress in Muhammadiyah high school students, and describe the role of Islamic religious education in the academic stress of Muhammadiyah high school students Banyuresmi.The method used in this research uses a qualitative approach using descriptive methods. As for the definition of descriptive according to Sugiyono, quoted by Melinda Rizky, namely a method that functions to describe or provide an overview of an object being studied through data or samples that have been collected as they are without carrying out analysis to make conclusions that apply to the general public. The results of this research show that Islamic religious education has an important role in students' academic stress, in the form of preventive measures by identifying things that are likely to cause students to experience academic stress, after which this is done, an initial conclusion can be drawn. The results of this study show that Islamic Religious Education (PAI) has an important role in students' academic stress, in the form of preventive measures by identifying things that are likely to make students experience academic stress, after which an initial conclusion is drawn by PAI teachers such as when there are too many tasks, then after it is known that when there are too many tasks will make it stressful,  PAI teachers reduce in assigning assignments. Curative steps or treatment are carried out by; Report to the student's homeroom teacher regarding their condition, coordinate with the counseling guidance teacher to conduct a home visit, tell the student to always maintain the quality of sleep and eating because it affects learning activities, always encourage them to always maintain the five-time prayer, dhikr to Allah, and be grateful as a solution to all problems, always motivate students to develop.

Abstract

Augmented Reality (AR) technology has made significant progress since it was first introduced by Thomas P. Caudell in 1992 as an industrial support tool. Today, the application of AR has become increasingly widespread, including in the field of education. This study aims to evaluate the effectiveness of Augmented Reality as a 3D-based learning medium to enhance student motivation for learning. The research was conducted with 32 third-grade students at SDN 1 Daroyon using a qualitative-descriptive research approach. Through a discovery learning approach, students were introduced to abstract concepts with the help of AR, which allows real-time visualization of virtual objects. The results of the study show that before using AR, 58% of students had very low learning motivation. However, after the implementation of AR, there was a significant increase in motivation, with 65% of students showing very high learning motivation. In addition to increasing interest and motivation, the use of AR also enriches students' learning experiences through interactive 3D visual features. This technology helps students understand abstract concepts in a more engaging and efficient way compared to traditional learning methods. The conclusion of this study emphasizes that integrating AR into the learning process can be an innovative approach to improving the quality of education. Specifically, this technology is effective in enhancing student motivation toward the subject matter. These findings support the importance of adopting modern technology in education to create a more dynamic and relevant learning environment in today's digital era.
