Main Material

Blood fever and Chikungunya cases in Indonesia are increasing annually. For preventing the mosquios, people use mosquito coil which is contain dangerous chemical compound. This research has successly created a natural mosquito coil with gemor bark and hazelnut fruit shell as the main material. Gemor bark is positive containing alcaloid,tanin, phenolk, flvonoid, triterpnoid and glycocydic compounds which are natural bioinsecticide. As formulation the comparison of gemor bark and hazelnut shell as follow :100% : 0 %  ; 80 % : 20 % ; 65 % : 35 % ; 50 % : 50 % ; 35 % : 65% and 20 % : 80% were used. Base one random variance analysis, the best formula was the using of gemor bark in 50%, 35% and  20% of concentration. The mosquitos killing force analysis was using the LT50 for 6 days with 5 diferent concentrations. The result showed that 50 %  of gemor bark was significantly influenced in the killing force. From the economic view, the producion of this coil was cheaper then the same product in the maket. Base on all the result, the research product is applicable in mass producion and safe for human health and the environment.Keywords: gemor bark , hazelnut fruit shell ,  mosquito coil, natural ,  ecofriendly

Ceramic Tile Production

Ceramic tile production is an industrial process where energy efficiency management is crucial, given the high amount of energy (electrical and thermal) required by the production cycle. This study presents the preliminary results of a research project aimed at defining the benefits of using combined heat and power (CHP) systems in the ceramic sector. Data collected from ten CHP installations allowed us to outline the average characteristics of prime movers, and to quantify the contribution of CHP thermal energy supporting the dryer process. The electric size of the installed CHP units resulted in being between 3.4 MW and 4.9 MW, with an average value of 4 MW. Data revealed that when the goal is to maximize the generation of electricity for self-consumption, internal combustion engines are the preferred choice due to higher conversion efficiency. In contrast, gas turbines allowed us to minimize the consumption of natural gas input to the spray dryer. Indeed, the fraction of the dryer thermal demand (between 600–950 kcal/kgH2O), covered by CHP discharged heat, is strictly dependent on the type of prime mover installed: lower values, in the range of 30–45%, are characteristic of combustion engines, whereas the use of gas turbines can contribute up to 77% of the process’s total consumption.
