School bench is one of the facilities that identified could cause musculoskeletal pain in school-age children. During class, students often sit with poor posture, back and neck bent in a long time so that musculoskeletal pain often occur in a classroom. Based on research conducted by Ira Idawati, school bench design needs to be different for each level of class because children have different anthropometric at each grade level elementary school-age. This can be done by designing school bench with fixed or adjustable size. If school decides to use fixed size bench, it is recommended to use several size of bench based on the level of the class. But if school used with adjustable size, the school could only buy one type and size of bench with a certain level of ergonomics. This study analyzed the used of the fixed and adjustable school bench design in elementary school based on economically and ergonomics. The result from this study shown that elementary student who sit on fixed size bench had a larger risk to the body than adjustable bench size from REBA and RULA scores. This suggests that adjustable bench was recommended for teaching and learning process facilities for health and to prevent injury on child. From economic terms, the value of the Net Present Value for fixed size bench is more economical than the adjustable one. From this two aspect, the elementary school had references to make school bench type decision.

Marine port as one important aspect of transportation network set particularly in marine field, should be able to support transportation activities or human and good transport from a place (hinterland) to another (foreland). Selection of port that could give best service would be one of important decision issues which would be giving positive impact toward regional economy surrounding the port in particular, and the nation in general. This study has taken object of Tanjung Perak port in Surabaya, particularly in container terminal. Policy development for regional economic growth in surrounding areas of the port was modeled by using dynamic system approach. Dynamic system approach could solve complex problems which cannot be solve by mathematical approach. Based on causal loop diagram, it is draw a dynamic system model such as stock and flow diagram to found out impact of changes in each variables affecting the system. Analysis result showed that economic growth rate in port was affected by several variables, in which port management has the authority to decide policies relevant with those variables. Thus, to increase regional economic growth in port surroundings, appropriate policy scenario to be initiated was to increase pier capacity and by adjusting tariff or retribution.

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.
