Artikel ini menyajikan efek penambahan komposisi CO2 dalam sistem refrigerasi kompresi uap yang menggunakan refrigerant Musicool 134. Penelitian dilakukan untuk mengetahui karakteristik katup ekspansi (TEV) dengan variabel komposisi CO2 dari 0%, 1,5%, 3% dan 5% pada kecepatan putar kompresor 1000 dan 1500 rpm, penambahan beban pendinginan serta penggunaan IHE. Pengukuran dilakukan dengan mencatat nilai tekanan dan temperatur masuk serta keluar katup ekspansi. Hasil penelitian menunjukkan bahwa penambahan komposisi CO2 meningkatkan tekanan masuk dan menurunkan tekanan keluar katup ekspansi.

Magelang memiliki tingkat kemacetan yang cukup padat pada beberapa ruas jalan terutama yang menuju pusat kota, salah satunya pada simpang Armada Town Square Mall yang kian hari semakin padat. Oleh karena itu, artikel ini menyajikan analisis pemborosan bahan bakar akibat kemacetan dengan menggunakan citra google map. Dalam penelitian ini metode yang digunakan dengan melihat panjang kemacetan pada google map, kemudian menghitung jumlah dan jenis kendaraan yang terjebak dalam kemacetan. Hasil penelitian menunjukkan bahwa kerugian ekonomi akibat kemacetan lalu lintas di simpang Armada Town Square Mall Magelang dari arah Yogyakarta sebesar 147,13 liter per hari untuk gasoline dan 777,82 liter untuk solar. Estimasi kerugian ekonomi akibat kemacetan lalu lintas dalam rupiah sangat bervariatif menurut jenis bahan bakar yang digunakan. Kerugian minimal dalam satu hari adalah Rp. 4.950.000,- ketika menggunakan premium dan solar subsidi, sedangkan kerugian maksimum adalah Rp. 9.940.000,- ketika menggunakan pertamax turbo dan pertamina dex.

Torque and Power Characteristics of Single Piston LPG-Fueled Engines on Variations of Ignition Timing Bagiyo Condro Purnomo; Noto Widodo

Liquefied Petroleum Gas (LPG) is an alternative fuel that has all key properties for the Spark Ignition (SI) engine. However, because of its properties, ignition timing on an LPG SI engine needs to be advanced from the reference angle to get the optimum performance. Therefore, this article presents the torque and power characteristics of a single piston LPG engine on variations of ignition timing. Evaluation of engine performance is carried out at the ignition timing of 15O, 17O, and 19O BTDC. The results showed the highest torque for LPG fuel was 10.64 Nm which was achieved at 3500 rpm with ignition timing of 19O BTDC, while the highest power for LPG fuel was 6.9 hp which was achieved at 5936 rpm with ignition timing of 19O BTDC.

Study on Cooling System for Parked Cars using Mini Air Cooler and Exhaust Fan Bagiyo Condro Purnomo; Indra Chandra Setiawan; Heru Adi Nugroho

Deaths among children and pets, as well as damage to car interior components, have been widely reported as a result of parking under direct sunlight for a long time. Rising car cabin temperatures in this condition trigger the formation of benzene gas, but it is not possible to turn on the AC due to security and energy consumption. Therefore, this article reports the experimental study on cabin cooling system for parked car under direct sunlight by applying a mini air cooler and exhaust fan powered by a solar cell on small car Bajaj Qute RE60. Two thermocouples were installed inside and outside the cabin to monitor the temperature for 7 hours, expressing daytime heat conditions. The results showed that this cooling system could reduce the temperature to 10 K by removing 8982 kJ (0.356 kW) of heat. In conclusion, this prototype is very promising to be developed and if implemented on a larger scale will reduce car interior damage while parking under direct sunlight.

In recent years, one of the most logical efforts made to reduce the dependence on fossil energy sources is the use of a gasoline-methanol fuel blend. However, the problem in using a gasoline-methanol blend as fuel is that the methanol will eventually separate itself from the gasoline unless they are properly blended together, this is because methanol has a polar hydroxyl group called monohydric that binds water vapor together, causing the mixture to separate. Previous research showed that adding a small amount of ethanol to the gasoline-methanol blend makes it a homogeneous blend. Therefore, this research aims to identify the exhaust emissions of the homogenous gasoline-methanol-(ethanol) blend. For each blended fraction was tested on a single-cylinder four-stroke engine. The emission test is carried out in two stages which include the gasoline mode, and the alcohol mode. These two measurement modes undergo a validation process to correct the differences in the measurement results of the gasoline-methanol-ethanol blends. The test results show that increasing the methanol fraction in the gasoline-methanol-(ethanol) fuel blend results in reduced emission of carbon monoxide and unburnt hydrocarbon because methanol has a high enthalpy of evaporation, which increases both volumetric efficiency and complete combustion. In addition, the increase in the methanol fraction in the gasoline-methanol-(ethanol) blend showed a higher increase in carbon dioxide emissions. This is because methanol and ethanol have a much lower energy content than gasoline. Therefore, its energy production per unit time requires more fuel molecules.
