This study examines the Ignition characteristics of blended fuel droplets with crude coconut oil and rhodium liquid as a liquid metal catalyst. The ignition behavior was observed by igniting the oil droplet on a junction of a thermocouple, and the droplet evolution recorded with the high-speed camera. The results show that the addition of a liquid metal catalyst successfully reduces the molecular mass of the triglyceride and weakens the bonding force between the carbon chain, and therefore the viscosity and flash point decreases. Moreover, the addition of liquid metal catalysts increased the reactivity of fuel molecules such as C-H, C-C, C = C, and C-O. Changes in the physical properties of the fuel, the geometry of the carbon chain, and molecular mass ease the absorption of heat by the fuel droplet, thereby increasing fuel ignition performances.

This study aims to reveal the performance and exhaust emissions of a spark ignition (SI) engine fueled by a gasoline-bioethanol mixture. The main performance characteristics of the SI engine tested are torque, power output; thermal efficiency, brake specific fuel consumption, and brake mean effective pressure. Meanwhile, the exhaust emissions seen are carbon monoxide and hydrocarbons. The test is carried out by comparing the performance of the SI engine under standard conditions without modification with gasoline fuel, with the SI engine with modification with 85% bioethanol fuel. The mass flow of fuel is regulated by modifying the carburetor choke at 3/4 and 7/8. The results show that although slightly lower than gasoline, in general, it can be seen that bioethanol can improve SI engine performance and produce environmentally friendly exhaust emissions.

Household sector as the second largest energy user after the industrial sector, thereality of what happened in Papua subsidized price of kerosene has reached Rp 6,000 - Rp10,000/liter due to government policy. Wood processing industry produces 40% of woodwaste which cause problems that impact on the environment. Need to use it into valueadded products, one of them as an alternative energy source to help alleviate the localeconomy.The method used in this study is an experimental analysis, by comparing the stovewithout the firewall and the firewall, and the temperature distribution was taken usinginfrared thermograph, and the other to obtain temperature data used infrared thermometer.The results of this study showed the exit temperature (out) with firewalls tend to behigher (591,1°C) compared with no firewall (583°C), because the firewall to isolate heat sothat the heat of combustion are all routed through the firewall to the outside of the pan isreinforced with color degradation results thermograph. But without the firewall and thetemperature rising back tends to decline because of the longer sawdust burning to ashes sothat has not been burned sawdust automatically drops down so that the distance of the potwith the heat source and the heat of combustion is much spread do not like using a firewall

Upaya manusia untuk menciptakan kondisi yang lebih sejuk dilakukan dengan sistem Air Conditioning (AC), salah satu AC yang digunakan pada sistem transportasi yaitu AC mobil. Coefficient of Performance (COP) merupakan perbandingan efek refrigerasi dengan kerja kompresor. Efek refrigerasi dikalkulasikan dari besarnya enthalpy refrigerant yang masuk kompresor atau enthalpy yang keluar dari evaporator dibagi dengan enthalpy refrigerant yang masuk evaporator atau enthalpy sesudah katup ekspansi. Secara lebih jelas bahwa Coefficient of Performance (COP) adalah perbandingan efektifitas pendinginan evaporator dengan kerja yang diberikan kompresor. Penelitian ini bertujuan untuk menghitung dan membandingkan Coefficient of Performance Refrigerant jenis R-134A, HFC-134 dan MC-134. Metode yang digunakan adalah secara eksperimental dengan mengkaji nilai efisiensi dari AC mobil toyota avanza 1.3cc dengan variasi Freon R 134A, HFC 134A dan MC 134. Hasil penelitian menunjukkan nilai COP aktual dan COPideal yang terbaik menggunakan MC-134 karena nilai konduktivitas termal MC-134 paling tinggi sehingga kalor yang diserap evaporator lebih tinggi yang membuat nilai dari COP yang didapat lebih tinggi. Untuk efisiensi kompresor yang terbaik menggunakan HFC-134 karena nilai viskositas dan densitas dari HFC-134 lebih tinggi yang membuat kerja kompresor lebih ringan sehingga membuat efisiensi kompresor lebih tinggi

The burning rate of coconut oil droplets has been investigated experimentally by adding bio-additives of clove oil and eucalyptus oil. Tests were carried out with single droplets suspended on thermocouples at room atmospheric pressure, and room temperature and ignited with a hot wire. The addition of clove oil and eucalyptus oil as bio-additives into coconut oil was 100 ppm and 300 ppm, respectively. The droplet combustion method was chosen to increase the contact area between the air and fuel so that the reactivity of the fuel molecules increases. The results showed that the eugenol compounds contained in clove oil and cineol compounds in eucalyptus oil were both aromatic, and had an unsymmetrical carbon chain geometry structure. Furthermore, this factor can potentially accelerate the occurrence of effective collisions between fuel molecules. Therefore the fuel is combustible, as evidenced by the increased burning rate, where the results show that without bio-additives, the burning rate of crude coconut oil (CCO) is about 0.7 seconds. These results are 0.15 to 0.2 seconds slower than CCO with bio-additive, which is around 0.55 to 0.6 seconds. Moreover, from the observations, it was found that the highest burning rate was achieved in both bio-additives with a concentration of 300 ppm.

The negative impact that can arise with the increase in the population of Papua and limited land for jobs in rural areas, and the use of natural resources that have not been maximized is the occurrence of unemployment. The existence of abundant coconut plants in the Sabron Sari Village, Jayapura Regency, has vast natural potential. However, the reality is that it has not been appropriately utilized so far, especially as an energy source. This community service aims to utilize coconut sap into bioethanol as an alternative fuel to replace kerosene. The method used in this program is socialization and training on the benefits and potential of coconut plants as an alternative fuel source, the process of making bioethanol, and its use on stoves. The results obtained from this program show that the people of Sabron Sari village have a new perspective on the potential of coconut plants and can have excellent skills and abilities in producing household-scale bioethanol from coconut sap.
