Abstract

Outboard Engine has been known and used as motor boat among of the residents of fisherman community in Tlocors village. Motor boats powered by outboard engine are not only used for fishing, but also used as marine tourism facilities. Considering the vital functional usage of outboard engine for Tlocor’s fisherman community and village community tourism groups  (Pokdarwis), for maintaining    economic livelihood, any interrupted items that happened during motor operation periods would be very significant impact on their daily life. Loss of income resulting from engine problem is the most of many potential cases occurred on the communities.   Hence, it is necessary to provide assistances for both Tlocors Communities, the fishermen, and village community tourism groups. Assistances were also considered part of the public service obligation to communities provided by the Institution.  Training on Outboard Engine Maintenance and Repair would become the scheme of the assistances. This tailor- made assistances would be targeted to both clusters. Better understanding and having a certain competency level on outboard engine maintenance and repair would have a significant value in order to empowering both communities, and become the main purpose of the assistance as well

Abstract

Based on data from the Indonesian Police and Fire Department, the number of fire incidents is quite high and the most frequent fires are residential buildings. Therefore, it is necessary to conduct research related to materials that can inhibit the spread of fire. This research was conducted with the intention of determining the ability of Tripotassium Citrate in sweet potato skin and Citric Acid in inhibiting the spread of fire. The purpose of this study was to determine which material is more effective by testing and combining the dosage of each material. The method used was to conduct an experimental test on the combination of these materials in inhibiting the spread of fire. The aspects measured in this study were the mass loss and the area burned from each sample. The experimental results show that Tripotassium citrate has a function in slowing down the fire ignition stage with a mass loss ranging from 0.67 - 0.97 grams and a percentage of burned area ranging from 17.54% - 23.85%. While citric acid has a function in slowing down the fire growth stage with a mass loss ranging from 0.01 - 0.17 grams and a percentage of burned area ranging from 1.75% - 7.08%. The combination of the two materials produced results with a mass loss ranging from 0.2 - 0.8 grams and a percentage of burned area ranging from 4.27% - 14.04%. With these results, it can be concluded that Tripotassium Citrate and Citric Acid can be used as fire retardants.

Abstract

Katalis dalam hidrogen generator sangat berperan penting dalam menentukan efisiensi produksi hidrogen yang nantinya digunakan dalam Proton Exchange Membrane Fuel Cell (PEMFC). Diantaranya KOH dan NAOH yang sering digunakan dalam elektrolisis air memiliki konduktivitas yang tinggi serta memungkinkan aliran arus yang lebih baik selama elektrolisis. Proses pengujian hidrogen generator menghasilkan 15 variasi hasil data kuantitatif dan kualitatif serta nilai break even ratio. Kualitas power density dan efisiensi fuel cell tertinggi terdapat pada katalis NaCl 0,05M namun dengan Spesific Fuel Consumption (SFC) terendah sebesar 0,58 kg/kWh. Nilai Break Event Ratio terbaik terdapat pada jenis katalis NaCl 0,05 dengan nilai 0,087. Penggunaan Katalis Air Laut memiliki nilai efisien tertinggi pada persentase 100% dengan efisiensi elektroliser mencapai 13,36% dan SFC terendah yakni 0,24 kg/kWh

Abstract

Hydrogen can be utilised through a Proton Exchange Membrane Fuel Cell (PEMFC) which has many advantages, namely more energy yield, higher energy density, no emissions, and no need for recharging compared to using batteries. The highest electrolyzer efficiency results were found on the 0.05M KOH catalyst with a value of 1.70% and it can be concluded that the higher the catalyst concentration, the higher the electrolyzer efficiency. The highest power density and fuel cell efficiency quality is found in the 0.05M NaCl catalyst but with the lowest Specific Fuel Consumption (SFC) of 0.62 kg/kWh, this indicates that the relationship between concentration and power density and fuel cell efficiency is directly proportional while it is inversely proportional to Specific Fuel Consumption ( SFC). The best Break Even Ratio value is found in the NaCl catalyst type 0.05 with a value of 0.082. The use of a seawater catalyst has the highest efficient value at a percentage of 100% with electrolyzer efficiency reaching 13.36% and the lowest SFC, namely 0.24 kg/kWh. Based on these results, the use of hydrogen generators for Proton Exchange Membrane Fuel Cells (PEMFC) needs to be developed.
