Abstract

Patchouli oil is the main ingredient of parfume as the binder of the fragrances. Patchouli oil is the distillates of patchouli’s leaves and stems. The distillation produces waste (dry leaves) which nowadays used as fertilizer, myrrh, mosquito coil, compost, and as the fuel of the distillation process itself. Up to today, the use of dry leaves as the distillation’s fuel is by burning them normally. We believe that this fuel can be used by other sectors by forming it as brickets. This research aims to find the right parameter combination of the patchouli’s dry leaves, stems, and other materials with taguchi’s method that hopefully can be used as household and even industrial fuels. Factors that contribute the most to elevates the average value of the combustion’s duration are the adhesive level, patchouli leaves’ carbon particle size, and drying duration. Whereas the combustion duration interval is 44,3036< Upredicted < 61,62.

Abstract

Abstract Performance appraisal is a key factor to develop an effective and efficient. Employees faced with a structured and systematic assessment to measure the achievements of the work. Unsatisfaction performance appraisal methods can be a polemical. It happens because of the gap between the expected value to the value of actual performance. Rating scale is one method affected bias and hallo effect.Therefore, it is necessary to design assessment methods better performance. The method of this research is 360 degree feedback. 360 degree feedback is methods in which employees receive confidential, anonymous feedback from the people who work around them.There are 24 employees were assessed in this study.The design competencies and sub-competencies in the performance appraisal form with a 360-degree feedback method prepared by adapting the managerial core competency.Based on 360 degree feedback method, there are many employees who get increased performance assessment compared to the previous assessment method. The increase was influenced by the contribution value of the co-workers, subordinates and themselves.

Abstract

Currently one of the organic fertilizer started being used is organic fertilizer from rabbit feces. In Pesanggrahan Batu area, there are about 25 farmers in each farmer has about 50 rabbits and joinning to "Paguyupan Ternak Karya Bagus". The problem is there still no standard composition of optimal organic fertilizer made from rabbit feces, so it is necessary to do a research to evaluate the composition of the organic fertilizer made from rabbit feces to get the high content of nitrogen, phosphorus and Kalium. Some factors used in this research related to the raw material for organic fertilizer are rabbit feces, bran, husk and probiotics factor with 3 levels of each factor, so then we select  experiment with orthogonal array 34 and 9 variations. The chosen orthogonal array table must have a minimum number of raw which is not less than the total number of degrees of freedom- in this research the total degrees of freedom is 8. Then do experiment in laboratory to check nitrogen (N), phosphorus (P) and kalium (K) content in the soil chemistry laboratory UB faculty of agriculture. Based on data analysis we get the combination of the level of high N content is by using a composition of 3000 g rabbit feces, EM4 10 ml and the amount of chaff 200 gr. The combination of the level that has the effect of generating a high phosphorus content value is the amount of rabbit feces at the level of 3000 g, the amount of EM4 at the level of 20 ml and the amount of chaff at the level of 400 g and level combination that has the effect of generating a high kalium content value is the amount of rabbit feces on level of 3000 g, the amount of rice bran at a level of 200 g, the amount of chaff at the level of 400 grams and the amount of EM4 on the level of 20 ml.
