In previous studies, the initial process of burning briquettes still takes a long time, i.e. app 15-20 minutes. In normal briquette burning, a flame comes out from the briquette hole surface. The purpose of this research is to find a solution to accelerate the burning process and then the solution to use this process easily. The main objective of this research is to examine the amount of heat generated from the briquettes burning process with the number of holes as much as 10, 12, and 14, and to measure the time of initial briquette burning until the first time the flame came out on the briquettes surface. The basic ingredients of briquettes used in this study were sago waste. The tools used are a moisture meter to measure the water content, an infrared thermometer, a temperature measuring instrument, a Stopwatch to measure time, a digital anemometer to measure the airflow speed. From this study, the results obtained indicate that the combustion process in a forced air convection conditions, resulting in the rate of heat transfer as follows: a). For using the 10 holes briquettes, the heat transfer rate is about 8.51 watts, b). In the burning of 12 holes briquettes, the resulting heat transfer rate is about 16.57 watts, c). While on the 14 holes briquettes burning, the rate of heat transfer is about 20.43 watts. When heat energy is applied to boil 5 liters of water, with a 10-hole briquette, the water boils within 23.54 minutes. When using 12 holes briquettes, the water boils in 21.31 minutes, and in the use of 14 holes briquettes, the water boils in 20.21 minutes. It is concluded that the shortest time to boil 5 liters of water is when using briquettes with 14 holes, which boils in 23.34 minutes. These results indicate that forced convection can speed up the briquette burning process and produce a fairly high temperature.

The existence of wood waste along the coast of Skouw Yambe is an abundant natural potential that has not been utilized properly. This Community Service activity aims to utilize the waste into briquettes as an alternative fuel to replace kerosene. The method used in this activity is the socialization, practice and training of making briquettes starting from collecting and drying raw materials, making wood charcoal, refining wood charcoal, mixing wood charcoal with adhesives, printing briquettes, drying briquettes, and cooking trials using briquettes. The result from this community service program is that the people of Skouw Yambe village can have excellent skills and abilities in producing household-scale briquettes from wood waste.

Tujuan dari penilitian ini adalah menganalisa seberapa besar potensi energi pasang surut air laut pada muara Pantai Amai, Pantai Bukisi, dan Pantai Tablanusu sebagai pembangkit listrik. Metode yang digunakan dalam penelitian ini adalah metode eksperimen di lapangan, dimana pengambilan data langsung di Muara Pantai Amai, Pantai Bukisi, dan Pantai Tablanusu.  Variabel yang didapatkan di lapangan: luas penampang muara, waktu, tinggi pasang surut, kecepatan aliran.  Hasil analisa dan perhitungan yang dilakukan pada ketiga tempat penelitian diperoleh daya listrik (energi pasang surut) yang dapat dihasilkan Pantai Tablanusu sebesar 55,329 kW, Pantai Amay sebesar 74,565 kW dan Pantai Bukisi sebesar 454,712 kW.  Muara Pantai Bukisi mempunyai potensi energi listrik (energi pasang surut) yang paling besar. Muara Pantai Amai dan Pantai Tablanusu juga memiliki potensi yang baik yang dapat dikembangkan menjadi energi bagi PLTPs.
