<![CDATA[Motor vehicle exhaust emissions containing carbon monoxide (CO) and hydrocarbons (HC) are a strategic issue for Indonesia, which has not yet set an age limit for motor vehicles. As a control measure, the Indonesian government itself has issued regulations on exhaust gas emission quality standards for motorized vehicles that are used by the public through Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 8 of 2023. Catalytic converter technology is the most effective system for reducing CO and HC emissions. Currently, it is from the Platinum Gold Metal (PGM) group, namely Platinum, Palladium, Rhodium which is still very expensive. This article uses a literature review research method with reference sources originating from previous research journals by comparing. This paper will discuss gas emissions, the development of converter catalytic materials and also the effectiveness of converter catalytic materials from the non-PGM metal group, namely Copper (Cu) and Brass/ Brass (CuZn) which has been proven to be able to reduce exhaust gas emissions so that it can be an alternative as a converter catitic at a more affordable price for the wider community]]>

<![CDATA[This study evaluates the potential of wet cassava stems, dry cassava stems, and dry cassava stem powder as biomass fuels for co-firing in power plants. The analysis includes proximate testing, calorific value, and ultimate analysis to determine the quality and combustion efficiency of each material. Proximate test results show that dry cassava stems have lower moisture content and higher ash content compared to wet cassava stems, which can affect residue and slagging in power plant equipment. The high volatile matter content and significant increase in fixed carbon from wet to dry conditions indicate a greater extractable energy potential. The gross calorific value shows a significant increase from 2676.11 kcal/kg (AR) to 4929.44 kcal/kg (DAF) for wet cassava stems, and from 3910.64 kcal/kg (AR) to 5046.48 kcal/kg (DAF) for dry cassava stems. Dry cassava stem powder shows a very high calorific value, reaching 4272 kcal/kg (DB). The best ultimate analysis results for cassava stem powder are carbon (C) 48.44%, hydrogen (H) 6.61%, oxygen (O) 43%, sulfur (S) 0.15%, and nitrogen (N) 1.80%.]]>

<![CDATA[The study of the effect of low temperature quenching cooling media on the value of toughness and types of fractures in AISI 1045 steel aims to determine the mechanical properties of increasing the value of toughness and ductility in steel. AISI 1045 steel is heated at a temperature of 850°C held for 60 minutes and then quenched quickly to a low temperature. The medium used is water. This tempering process can increase the impact energy. The impac energy value obtained at a temperature of 350°C is 18,33 Joule. Then at a temperature of 450°C it increases by 80 Joule, after that it increases again at a temperature of 550°C which is 121,33 Joule, the value increases higher at a tempering temperature of 650°C by 135,67 Joule. Observation of the type of fault shows that the higher the temperature the more ductile it can be seen from the results of the uneven and fibrous surface. Impact energy is influenced by variations in tempering temperature. When the tempering temperature is increased, the impact energi also increase. Keywords: AISI 1045 Steel, Quenching, Tempering, Impact Energy, Types of Fractures]]>

<![CDATA[The increasing consumption of local clam shells which contain high nutritional value in society has resulted in an increase in waste sea shells in areas around the coast of Bengkulu Province. The high calcium content in lokan clam shells attracts researchers to study the physical and mechanical properties of epoxy resin composites reinforced lokan clam shell powder. This research aims to investigate the effect of variations in the volume fraction of lokan clam shell powder and the mold loading on the physical and mechanical properties of composites reinforced lokan clam shell powder. The process of manufacturing shell powder is carried out by heating at a temperature of 900oC for 6 hours. Variations in the volume fraction of lokan clam shell powder consist of 30, 50, 70%. Meanwhile, the mold loading was varied by 0, 500 N, and 1 kN. The manufacturing process uses hand lay-up techniques. Physical and mechanical tests on composites include water absorption tests, density, tensile tests and impact tests. The results of the research show that the powder volume fraction and mold loading influence the physical and mechanical properties of composites reinforced lokan clam shell powder. The best physical properties of composite were obtained at a powder volume fraction of 70% and a mold loading of 1 kN, namely with a density of 1.43 g/cm3. The best mechanical properties of composite were obtained at a volume fraction of 30% and a mold loading of 1 kN, namely with a tensile strength of 33.2 MPa and an impact toughness of 366.8 kJ/m2.]]>

<![CDATA[The growth of motorized vehicles in Indonesia reached 4.1% with a total number of vehicles of 136,137,451. Vehicle units operated on the highway will cause an increase in noise on the highway caused by the operation of vehicle horns. The Indonesian government has regulated horn noise quality standards through Peraturan Pemerintah Nomor 55 Tahun 2012. Indonesia has agreed to the Asean Mutual Recognation Agreement (MRA) for automotive product standards in the Asean region referring to UN ECE where for horn testing it refers to the UN ECE R28 Part II standard. From testing the horn at durations of 1, 5, 10 and 15 seconds using a battery and an idle engine, there was no significant difference in the resulting horn sound level. This research aims to ensure the source of electric current when testing the horn so that the test can run more effectively and efficiently by establishing in the operational standards the UN ECE R 28 Part II test procedure using a battery only]]>

<![CDATA[The chassis is part of the vehicle and requires a strong structure and structure to withstand loads. This part also has the function of maintaining rigidity so that the vehicle does not bend. Damage that commonly appears in Chassis Crash Car X is cracks and corrosion. This study aims to analyze the presence of cracks and corrosion in the chassis of his ARFF crash car type 1 X vehicle at Juanda Surabaya International Airport. The researchers also examined the chassis of the ARFF crash car-analyzing another type of Type 1 vehicle, namely the ARFF crash car Type 1 Y and Z. This study uses qualitative research methods to determine the chassis characteristics of a Type 1 ARFF crash car in service at Juanda Surabaya International Airport. Data analysis using FEM using the Solidworks application determines the values of von Mises stress and chassis displacement versus load and uses calculations to determine the corrosion rate. From the analysis results, the von Mises stress value was close to the yield point value of the material used, the displacement value was the highest, and it had the shortest life. Apart from that, it can be concluded that one of the causes of cracking and corrosion is due to the use of double frames, thus the presence of air gaps as a cause of corrosion formation. Chassis merupakan salah satu bagian kendaraan yang harus memiliki susunan dan konstruksi kuat untuk menahan beban. Bagian ini juga memiliki fungsi untuk menjaga kendaraan agar tetap rigid dan tidak mengalami bending. Kerusakan yang umumnya dialami oleh chassis crash car X adalah crack dan korosi. Penelitian ini bertujuan untuk melakukan analisa terhadap adanya crack dan korosi pada Chassis kendaraan ARFF Crash Car Tipe 1 X yang dimiliki Bandar Udara Internasional Juanda-Surabaya, di samping itu peneliti juga akan melakukan analisa Chassis kendaraan ARFF Crash Car Tipe 1 untuk jenis yang lain yaitu ARFF Crash Car Tipe 1 Y dan Z. Penelitian ini menggunakan metode penelitian kualitatif untuk mengetahui karakteristik dari chassis dari ARFF Crash Car Tipe 1 yang digunakan Bandar Udara Internasional Juanda-Surabaya. Pada proses analisa data menggunakan FEM dengan bantuan aplikasi solidworks untuk mengetahui nilai von mises stress dan displacement chassis terhadap beban dan menggunakan perhitungan untuk mengetahui laju korosi. Dari hasil analisa diperoleh hasil chassis merk X memiliki konstruksi yang paling kurang baik dibandingkan chassis Y dan Z, dikarenakan nilai Von mises stress mendekati nilai yield strength material yang digunakan, memiliki nilai Displacement yang paling besar dan umur yang paling pendek. Selain itu dapat disimpulkan bahwa salah satu penyebab adanya crack dan korosi karena penggunaan double frame, sehingga ada celah udara sebagai penyebab terbentuknya korosi.]]>
