Abstract

A Production planning is very important to all activities in manufacturing company. For a company producing a variety of product the production planning will be complicated. In this case it’s necessary to make an aggregate production planning. A Company has goals to achieve the products, althought there differenciate between each other. Other wise, if needs to make a production planning that accommodate such goals.Goal programming model  can be used for aggregate production planning. This multi objective model can accommodate more than one goal which will be achieved by the company. Product demand forecasting is input for aggregate production planning. From this aggregate production planning, futhermore, disaggregation must be conducted, then it will be continued by raw material planning. The raw material planning is made by lot size each order economically.   The aim of goal programming model is to maximize profits, to minimize subcontract products amount, to minimize overtime labours cost and to minimize inventory amount. The results show that the goal programming model could accommodate three goals that will be achieved by the company, except that goal to maximize profit high goal is to minimize inventory amount. The comparison between planning and realitation show that the goal programming model could reduce the minimize overtime labours cost.

Abstract

Rainfall is one of hydrology components that may be affected by climate change. The change of rainfall pattern can cause much impact on many fields. Many researches about global and regional climate change projection have been conducted. However, research about local scale of climate change based on climate character in local area is still necessary for a better result. Area of this research cover southwest slope of Merapi Mount, Java Island, Indonesia. Automatic rainfall data records from 1989 until 2008 of nine rainfall gauges in Merapi Mount’s southwest slope is available. Those data series this research is only adequate for climate variability analysis. The methods to detect trends in this research is non parametric test (Mann-Kendall test). The results show that at level of significance 5%, trend of rainfall in Mt. Merapi slope area is statistically not performing a specific pattern. Wet season occur every November until April while dry season occur every May until October. Neglect of trend signification, annual rainfall has decreace tendency. Rainfall amount in the beginning of wet season has increase tendency while rainfall amount in the middle of wet season and dry season have decreace tendency. Maximum daily and hourly rainfall also have decreace tendency.Spatially, annual rainfall and maximum daily rainfall increased from lower to higher elevation, from east to west and from south to north.

Abstract

Student dormitory is one of the facilities provided as a means of support for the students in their studies in Universities. Because many students who come from outside the region where the study was held. Dormitory students have an important role in supporting the successful development in the field of education as well as business opportunities to boost the economy of the people who live around educational institutions. However on the other side where the hostel will generate waste, among others, feces and urine, organic and inorganic garbage and domestic waste which if not managed properly could potentially cause health problems, and aesthetics. The problems that have been faced by managers and occupants of a student dormitory in the Kelurahan Sungai Besar, Kecamatan Banjarbaru Selatan, Banjarbaru City is the lack of knowledge of how the processing waste human manure, organic waste and domestic waste water so it does not pollute the surrounding environment and at the same time converting the processed organic waste into a resource new energy, namely biogas and compost.Digester technology applications will generate a set of tools Human waste processing manure, organic waste and domestic waste. This technology is the processing of organic material anaerobic digester technology in the form of organic waste that the waste that comes out of the digester safely discharged into the environment. Aside from being a waste treatment plant, the solution can also produce biogas to biogas formed later expected to be utilized as a fuel substitute for LPG and fuel Generator Set (Genset) as a substitute fuel (gasoline) in addition produce a byproduct of compost were also no less economic value. Inside the digester hydrolysis and fermentation process occurs, phase Acetogenesis and methanogenesis phase of organic waste into biogas and its byproducts are composted. The process takes 20-30 days. Wastewater digester output of the reactor is no longer harmful to humans, the environment and other living organisms that are not harmful to the environment if disposed of.

Abstract

The study focused on analyzing the failure of the sun gear section of the swing drive excavator, where there has been a failure in operation. The gears are predominantly damaged in certain areas while other areas appear to have minimal failure. To answer the cause of failure of the gear, 3 stages of testing are carried out, namely; macro observation, chemical composition test and hardness test and loading simulation. The results of this test are that failure occurs due to case crushing caused by residual stresses under the surface of the gears, the detached surface and pinnion conditions exposed to the soft parts become more vulnerable so that scoring occurs causing macrowelding.
