This study looked at the condition of power loss and falling voltage after the evaluation of the medium voltage network 20 kV after the earthquake disaster in South Halmahera district, especially in labuha extension on Bacan island The method used in this study is a quantitative research method with data collection done which is then simulated using ETAP 12.6 software. The simulation result obtained total power loss at Labuha extension is 44.3 kW + 66.8 kVAR or 80,154 kVA of 2,445 MVA delivery power, while the presentation of power loss is 3.278%, this is still considered feasible because the power loss on the medium voltage network 20 kV is 10% while in Labuha turtles the power loss is less than 10%. While the large fall in voltage at the largest Labuha extension at the Belang-Belang distribution substation is 3.96% or 792 volts, this is due to the channel length and presentation of the load reaching 83% against the distribution tranformator and the fall in the average voltage of Labuha's purgator is 3.025% or 605 volts against the nominal voltage of 20 kV. It is still considered viable for operation due to the permitted voltage fall on the 20 kV medium voltage network which is 5%.

Cloves are one of the leading agricultural commodities in North Maluku. The main product of the clove plant is clove flower. The clove flowers used in the production of kretek are dried cloves. Drying clove flowers can be done in two ways, first traditionally by drying them in the hot sun directly, and second by using an artificial dryer. Drying by drying directly in the sun or traditionally has several weaknesses, namely dependence on the weather, causing damage to clove flowers due to too long drying and the need for a large area for drying. The purpose of this research is to design and manufacture a clove dryer equipped with a biomass furnace as a heat source. The research method that will be carried out in this research is experimental research, by designing and building a clove dryer equipped with a biomass furnace as a heat source. The result is a clove dryer with dimensions of 120 cm long, 80 cm wide and 80 cm high. clove dryer equipped with 3 shelves with a distance of 20 cm between the racks. The clove dryer test results show that the time required to dry 18 kg of wet cloves is 13 hours with temperatures in the drying room 49 ℃ to 55 ℃.
