Abstract

Most Public Regency Manokwari West Papua Province had used kerosene as fuel to cook whereas kerosene was known very no friendly environment because of kerosene produced very high emission of carbon monoxide (CO2). For limit use kerosene fuel, need searching for stove using fuel that has high efficiency however CO2 emissions level and cost were low. Purpose from study this was identify a number of fficient stove in using fuel, CO2 emissions and cost of fuel were more low. Tested stoves were electrically induction stove with a number of power (300W, 700W, 1000W, 1200W, 1400W, 1600W, 1800W, 2000W), stove electricity element consisted of two powers (1100W and 500W), kerosene stove 22 wicks and 16 wicks and LPG stove . Method used in this study was semi-empirical method , where in this research use pure water as much as 500 ml, which is heated from 27 o C to 100 o C, with use stainless steel receptacle with cover from glass. Results of study showed that electrically induction stove with 2000W power given the fastest cooking time (2.15 minutes) however with 1400W power cooking time electrically induction stove more fast than the other stove. Highest efficiency obtained from electrically induction stove (84%-88%), elemen electric stoves 50%-53%, LPG stove 46.38%, and kerosene stove 10–12%. Emission of CO2, the most low obtained from electrically induction stove (182–190 g CO2), kerosene stove 130-153 g. Lowest cost for cooking 500 ml obtained from electrically induction stove with IDR. 94–106, elemen stove IDR. 150–180, LPG stove IDR 210, and kerosene stove IDR. 225–261. Electrically induction stove is the best stove, which had highest energy efficiency, CO2 emission level and cost were low.

Abstract

This study determined the management of disaster risk reduction in Wamesa Village, South Manokwari District, West Papua Province, and evaluated the level of vulnerability, capacity, and risk of the tsunami catastrophe threat. This research is a quantitative and qualitative research that uses analytical descriptive methods that describe the context of vulnerability and capacity in the research location. The primary data were collected through interviews with community development cadres of Wamesa village as well as documentation (mapping) of social, economic, physical and environmental data at the research location referring to the technical research guidelines for tsunami disaster risk study. Secondary data to see potential threats as well as vulnerability and capacity level assessments were obtained from the relevant agencies. The results found that the level of vulnerability and capacity of the Wamesa village community to the tsunami disaster was categorized as high with a vulnerability and capacity index values were 2.21 and 2.54, respectively. Wamesa village, in general, is at intermediate risk of a tsunami disaster, with a total of 0.92 ha of the hamlet's land area being at low risk, 46.13 ha being at moderate risk, and 2.91 ha being at high risk. The management of disaster risk reduction in Wamesa village needs to be strengthened by integrating risk assessment and disaster mitigation activities into village planning and budgeting so it can be sustainable and contributes to reducing vulnerability and increasing the capacity of the Wamesa village against the threat of a tsunami disaster.
