Abstract

Ikonos satellite image is an image that has a high spatial resolution with pixel accuracy of one meter for panchromaticand four-meter multispectral. Spesifkasi IKONOS imagery provides the ability to record an object one meter.Therefore the use of Ikonos imagery to identify objects and buildings Land Tax (PBB) is dimungkinkan.Untukdetermine the ability of Ikonos imagery in the identification of objects Land and Building Tax (PBB) conductedresearch that aims to determine the accuracy of the interpretation of Ikonos imagery for identification of objectsUN, UN to map objects based on Ikonos imagery interpretation, field survey and evaluate the results of BlockMaps uses map image interpretation Ikonos.Penelitian geografi.Pengumpulan using descriptive methods of datais done through the interpretation of Ikonos imagery, field tests, interviews and documentation. Data analysis isthe analysis of the level of image interpretation, analysis and map overlay analysis. The results showed that thelevel of interpretation of Ikonos imagery for identification of objects and the United Nations is 89.54% commissionerror is 10.46%. Results from a block map using Ikonos imagery interpretation of evaluation results have not yetregistered 269 objects in the map of Block UN tax. Can be concluded that the Ikonos imagery can be used as theprimary data source for identification of objects.Key words: Ikonos image, image interpretation, object identification, remote sensing, object of property tax.

Abstract

The research was aimed to reveal and document hereptofauna from Girimulyo District Kulon Progo Regency,Daerah Istimewa Yogyakarta Province. This research was done from November-Desember 2008 and January-April 2009 in four research locations were Girimulyo, Jatimulyo, Giripurwo and Purwosari. The VES (VisualEncounter Survey) method were used and combined with interview method.. A total of 40 species of herpetofaunaare indentified and includes in to 13 family. Among 40 species, only one (Michrohyla achatina) is endemic to Java.The commonest herpetofaunas along all site were Eutropis multifasciata and Hylarana chalconota.

Abstract

Equitable health care is a basic right for citizens and must be fulfilled by the government. This research analyzed communitydiscrepancy in access to reach health services in public hospitals and Puskesmas (health centers) in Banyuwangi Regency.This research identified community accessibility to health facilities services using travel time and transport modes choiceas indicators. Flowmap tool is used to analyze catchment area of each health facility using different transport modes choice:becak and public transport for poor group and motorcycle and car for non-poor group with different travel time within 30, 60 and more than 60 minutes. It is concluded that there was an accessibility difference between poor and non-poor group. The accessibility to the health facilities of poor group was lower than non-poor group. This condition occurred because the government policy of equitable access to health service facility did not pay attention to accessibility of poor group.

Abstract

The main goal of this work is to investigate the use of air jet cooling on machining process. Surface roughnessand tool are chosen as parameter to analyze of air jet cooling effects; and turning process with AISI 1010 materialused in the experimental study. Surface roughness was measured for several air jet pressures and in two air jetpositions. Every five minutes of machining time, tool wear was measured until reach 30 minutes. Initial resultsshow that the use of air jet cooling with proper selection of position and pressure; possible to reduce tool wear andto increase surface roughness.

Abstract

Wooden furniture industry is an important industry sector in Indonesia, because many people’s welfare relyon this industry sector and the industry has a big social and environmental impacts. Many wooden furnitureindustries in Indonesia, especially in Central Java Province face problems related to the sustainability. The relationbetween wood suppliers and furniture industry is studied in this paper. A sustainable supply chain management (s-SCM) model is proposed as an approach for solutions for the problems. The approach is chosen due to the characteristics of the problems that related to economic, social, and environmental problems. This aim of this paper is to determine how much supply teak wood must be provided by PP to satisfy furniture industry demand, how much production capacity that must be increased and how large forest area that must be planted in order to achieve environmental and social goals without sacrificing economical goals much. Goal programming (GP) is chosen for solving the problems, because the goals are to maximize the total benefit,minimize the total loss and anticipate the conflicts between goals. Numerical trial based on observation in teak wooden furniture industry in Central Java was used to illustrate our findings. Using pareto efficient principle, the model can satisfy all goals that need to be achieved. Numerical results can be used by decision makers in teak wood industry to analyze the trade-off among several set of alternative solutions.

Abstract

In Indonesia, it is about 40% patients with hard tissue defect due to ostheoporosis, cancer or accidents and therest are defect since they have born.For many years, efforts for recovering have been done by transplantation orimplantation methods.Transplantation is more appropriate butit is not sustain because of limited donor, whileimplantation using synthetic materials such as bioceramics scaffoldis expensive due to import and the scaffold iseasier to break which does not match to the medical requirements.The research therefore has been addressed to thisissue. Local bovine hydroxyapatite (bHA)scaffold has been used as thebase material and poly vynilalchohol (PVA)as a coating material.The bHA scaffold was prepared by cutting a fresh bovine bone in the size of 5mmx5mmx5mmand boil it in a distilled water to remove its organic material. It was then heated up at 900 oC for 2 hours infurnace to obtain bovine hydroxyapatite scaffold (bHA). Coating process has been carried out by dip coating of thebHAscaffold in PVA solution.

Abstract

In order to use piston prover OT-400 calibrator more effective is to know the relationship between pressure piston and water flow rate. Water flow rate measurement by using piston pressure variation and setting of proportional directional solenoid valve has been done on piston prover OT-400 calibration sytems. Selection variation of piston pressure condition has been done at four measuring points there are 20 PSI, 42.5 PSI, 62.5 PSI and 80 PSI. Giving of voltage variation for ascending and declining to the solenoid is to set the opening and closing its valve. From the measurement results obtained that the water flow rate is proportional to the piston pressure used. Graph of water flow rate (Q) with unit of liters / minute versus the piston pressure (P) with unit of PSI within the setting ofproportional directional solenoid valve on the piston prover OT-400 calibrator has linear type that is Q = 0.002. P + 0.151 with R2=0,998. While the graph of the average uncertainty value of the measuring point versus pressure piston is not a linear form with the smallest value of 2.31% on the use of piston pressure of 80 PSI
