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.

Abstract

Manual Materials Handling (MMH) activities still widely used in a job. This is because in this activity has a high flexibility, inexpensive, and easy to apply. However, these activities also constitute a risk when applied to the inadequate  environment, less support of tool, and bad posture of work. Therefore, measurement of safety limit in doing the job by using a calculation based on the equation of NIOSH Lifting Index. The case study at PT. Central protein Prima Surabaya is the removal of shrimp feed bag that still use manual way. Acquisition of STRWL calculation results obtained for the removal of shrimp feed bag stacks 1, 2, 3, 4, 5, 6, and 7 from 5,003 Kg to 67,41 Kg. Actual load which worker must lifted in this case study on a pile of 1 to 7 is 25 kg. Load  is lifted for the removal of shrimp feed bag bigger than STRWLmake it not feasible. CLI obtained in shrimp feed bag removal activity is 6.041 which value exceeds 3. Therefore CLI in this case study may create a risk of spinal cord injuries and to do their job changes. By measuring the changes in safety limits and do the work, expected reduced risk of injury to workers. After measuring the safe limit for the removal of bag obtained load is lifted workers have the risk of spinal injury, so it is given recommendations for improvement is by doing a redesign on a conveyor in the form of additional elevation (vertical) 57 cm at the end of the conveyor, as well as shortening the horizontal distance between the worker's body with a bag of shrimp feed time of transfer. With these recommendations obtained a decrease CLI becomes 1.795, which means that the risk of injury is between 1 <CLI ≤ 3 and can be reduced.

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

Time is one of the factors to assess a worker's performance in utilizing the available resources. Operator in his work requires efficient time to improve work productivity. One of factory in produce a shrimp feed in Surabaya has a large production level. In the production process, the packaging department in this company still uses human resources in their production process and the company define the standard of production without using standard time. This paper investigates the opportunity a logical analysis in determining the standard time in this company. The determination of the standard time in the packaging process requires comprehensive analysis. Objects observed are four operators in the packaging department that carried out the activities of filling bag the shrimp feed with 40 replication for each data. The work measurement was conducted by direct method using Stopwatch Time Study (STS) with snap-back method. The results of this study indicate the standard time value of the four lines packaging is not much different or almost the same. Sequentially the standard time workers line 1 to line 4 is 7.325 seconds, 7.240 seconds, 7.225 seconds, and 7.065 seconds. Allowance used for workers is 8%. However, the existing production rate of company is higher than the production rate of work measurement calculation. This is due to the difference of definition in employee allowance rate and performance rating.

Abstract

Fruit Chip is one of the most well known Small Medium Enterprise’s products in Batu Malang. This is due to the high number of fruit production produced in this city. In selling their products, local Small Medium Enterprise have to face the highly competition from other producers as well who also produced similar products. The increasing number of tourists who came into Batu City also encouraging local Small Medium Enterprises to capture this opportunity by producing food souvenirs such as fruit chip. Therefore, every local Small Medium Enterprises should make continuous improvements in all areas as well as improving the quality of their products especially to maintain and attract the consumers. One of the key areas that need to be developed is marketing by conducting marketing research. This marketing research is conducted by observing the marketing environment (X1) and marketing mix-7P’s (X2) towards the customer satisfaction (Y) using Structural Equation Modelling (SEM). Based on the regression analysis, we can conclude that there is significant correlation between marketing mix towards customer satisfaction. The most influential variable in marketing mix is employee, promotion, process, and places. While the biggest influence in marketing environment is new entrants and customer variables.
