Abstract

This study aims to determine the effect of the geometry shape of the copper material heat sink fins on the surface temperature distribution of the heat sink. The material used in this research is pure copper, the shape of the heat sink fins is made rippled with the addition of the number of fins 5, 6, and 7 and the input temperature is varied from 40 C to 80 C with airflow variations from 0.2 m/s to 1 m/s. The first step is to create a heat sink design with Autodesk Inventor. Then the plan is simulated with Autodesk CFD to solve the continuity, momentum, turbulence, and energy equations. Based on the method that has been carried out, it is found that the addition of variations in the number of fins affects the decrease in surface temperature. The highest temperature drop on fin 5 ripples is 24.1 C. The heat energy transfer rate increased by 0.4657 W. The convection heat transfer coefficient  increased by 3.47 W/m²C. Nusselt number shows an increase of 271. Fin performance has increased efficiency by  63.4 %, and effectiveness by 1.61. The results of this study are expected to provide practical alternatives that can be widely adopted on a heatsink plate that is very promising for future thermal developments.

Abstract

The main objective of this community service is to provide some support and guidance to the Small and Medium Enterprises (SMEs) within the Women Farmers Group (KWT) Barokah in Pagedangan Village. Specifically, the assistance aims to facilitate the acquisition of halal certification, which is crucial for enhancing their competitiveness in the global market, given the increasing demand for such certification in the halal industry. It is imperative that forward-thinking SMEs understand the possible commercial advantages linked to halal certification. This program gives SME owners in Pagedangan Village informational materials and advice on the halal certification procedure. The project focuses on the business owners of KWT Barokah, which comprises 22 SMEs a relatively small number in comparison to the overall population of Pagedangan Village. These businesses include sectors such as frozen food, meatball products, catering, flavored milk beverages, herbal drinks, pecel peanut sauce, sukun chips, and Gabin cake filled with tape, among others. The assistance addresses specific issues identified by the community service team and offers tailored solutions to assist these entrepreneurs in obtaining halal certification. The anticipated outcome is that SME owners will enhance the quality of their products through halal certification and improve their readiness to compete in the halal market.

Abstract

Bioheat transfer is a combination of heat transfer and biology process comprising of transfer of heat from human living tissue to the environment. This study aims to estimate the temperature distribution of female human’s skin. In this study, effect of varied blood perfusions of 1.5, 2.0, 2.5 and 3.0 kg/s.m3 on bioheat transfer of female human skin, which was modeled into four layers, was simulated. To address this issue, one-dimensional unsteady state finite difference method was applied in this study.  Result of this study informed that the finite difference method can be used to solve the bioheat transfer equation and to estimate temperature distribution of different skin layers of female human. In this study, blood perfusion affects temperature distribution in the four layers of unstable women's skin. The highest blood perfusion of 3 kg/s.m3 resulted in more homogeny temperature distribution of different skin layers. This circumstance occurred since higher blood perfusion increases heat transfer between blood and skin layers.

Abstract

The thermal protective performance is provided by thermal protective clothing worn by people who work in high temperature environments and is highly influenced by air gaps. In this paper, effect of air gap thickness on thermal protective performance as indicated by the time before degree burn were investigated. 3 layers of thermal protective clothing with 3 types of fabrics that have been selected will be tested using an experimental method. The research will be conducted through experimental tests using the fabric level method on a bench-scale test apparatus which is equipped with 4 thermocouples and using gas torch as a heat source. The air gap located between the layers of thermal protective clothing will be varied with different thickness in a vertical orientation. The size of the air gap used varies from 01 mm, 2.51 mm, 51 mm, and 7.51 mm. The results show that the temperature distribution in each layer of clothing from the outer shell to the thermal linear has decreased. In addition, time before degree burn which is an indicator on thermal protective performance shows a positive effect on the addition of air gap thickness where the optimum air gap thickness is shown at 7.5 mm variation. It is hoped that the results of this research can be a source or useful information in mechanical engineering, especially in the fields of thermal comfort and fire safety.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi dampak penggunaan kendaraan bermotor terhadap siswa di SMAN 1 Mimika. Dengan menggunakan pendekatan kualitatif, data dikumpulkan melalui kuesioner yang menyoroti keterlambatan datang ke sekolah, risiko kecelakaan lalu lintas, paparan polusi udara, sikap, dan perilaku siswa terkait transportasi, serta kesiapan mereka untuk mengadopsi alternatif transportasi berkelanjutan. Analisis data menyoroti bahwa penggunaan kendaraan bermotor berkontribusi pada kemacetan lalu lintas, meningkatkan risiko kecelakaan, dan memperburuk kualitas udara di sekitar sekolah. Sikap dan perilaku siswa cenderung bervariasi, tetapi ada kesadaran meningkat akan pentingnya transportasi berkelanjutan. Implikasi dari penelitian ini adalah perlunya langkah-langkah konkret untuk mengurangi penggunaan kendaraan bermotor, mempromosikan transportasi berkelanjutan, dan meningkatkan kesadaran akan dampak negatif penggunaan kendaraan bermotor terhadap siswa dan lingkungan sekolah

Abstract

Technological developments have resulted in an increasing number of motorized vehicles such as motorbikes, cars, and other modes of transportation, which will result in a lot of air pollution due to exhaust emissions from fossil fuels. Substances from the hazardous exhaust gases include carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NO or NOx), and hydrocarbons (HC). This research was conducted by designing a catalytic converter using a mixture of several metals obtained from various wastes in Small and Medium Enterprises. A mixture of copper, brass, aluminum, and zinc is to be made as a muffler or exhaust on the test vehicle, namely the 2005 Car with observed exhaust emissions, namely CO & HC, using a Gas Analyzer. Measurements were taken at vehicle rotation of 1000 rpm, 2000 rpm, 3000 rpm, 4000 rpm, and 5000 rpm. The results of this study indicate that the highest percentage reduction in CO levels was when using a catalyst with an engine speed of 2000 rpm, which was 5.23% with Pertamax fuel, while for Pertalite fuel, when using a catalyst with an engine speed of 2000 rpm, it was 5.5%. The highest percentage reduction in HC levels was when using a catalyst at 1000 rpm engine speed of 645 with Pertamax fuel, while for Pertalite fuel, using a catalyst at 1000 rpm engine speed was 705.5.   Keywords: Aluminium, Brass, Catalytic Converter, Copper, Gas Analyzer, Zinc

Abstract

The low level of students' ability to read and write the Qur'an remains an important issue in madrasas, especially at the secondary level. This condition requires appropriate, focused, and sustainable learning strategies, one of which is through strengthening extracurricular activities. This study aims to describe the strategies for teaching Quranic literacy in extracurricular activities at MTs Al-Anshar Tanjung Selor. This study uses a descriptive qualitative approach with primary and secondary data sources. Data collection techniques included interviews, observation, and documentation, while data analysis was carried out through the stages of data collection, data reduction, data presentation, and conclusion drawing. The results showed that the strategies for teaching Quranic reading and writing were implemented through the imla and demonstration methods, which were tailored to the abilities of the students. Supporting factors for learning included readiness to learn, motivation, and student characteristics, while inhibiting factors included time constraints, the learning environment, learning objectives, and the management of extracurricular activities. The findings of this study imply the importance of strengthening planning, effective time management, and the development of contextual learning strategies so that the implementation of the Qur'anic reading and writing extracurricular activity runs more optimally and sustainably.
