A SUSTAINABLE SUPPLY CHAIN MODEL OF RELATIONSHIP BETWEEN WOOD SUPPLIER AND FURNITURE INDUSTRY IN INDONESIA
No full textWooden 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

No full textAerobic fitness can be used as a health indicator. The purpose of this study is to investigate the effect of Body Mass Index,gender, and physical activity on the aerobic fitness. Twenty females and 27 males students in range of 20 ± 1.2 yearsold, height 164 ± 8.95 cm, and weight 58.23 ± 9.5 kg that meet inclusion criteria were used as subject that measuredin Ergonomics Laboratory Gadjah Mada University within room temperature 25-26oC and 40-50% in humidity.Four methods of indirect measurement (VO2max as an output) is used to measure aerobic fitness: nonexercise skinfoldmeasurements and Body Mass Index, Astrand bicycle, treadmill, and the fitness index Harvard Step Test performed ondifferent days. The results showed that gender (rs = 0.838 on the nonexercise BMI) and BMI (rs = -0.677 on the Astrandmethod) effect on aerobic fitness. The average value of VO2max (ml.kg-1.min in-1) is achieved from each method. Formale, Astrand bicycle = 53.24 ± 7.82, treadmill = 38.43 ± 9, 05, BMI = 44.85 ± 3.45, 42.49 ± 3.38 = skinfold. Forwomen, Astrand bicycle = 47.86 ± 8.59, ± 5.73 treadmill = 34.1, BMI = 34.25 ± 2.46, 34.63 ± 2.51 = skinfold
EQUITABLE ACCESS TO HEALTH SERVICE IN BANYUWANGI
No full textEquitable 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
IDENTIFIKASI EFEK DEPRESAN SSP (SUSUNAN SARAF PUSAT) ANTIKEJANG DAN NEUROTOKSISITAS SENYAWA 4-KLOROBENZOILTIOUREA PADA MENCIT PUTIH JANTAN
No full textThe study on the development of benzoylthiourea derivatives as central nervous system (CNS) depressants was based on their structure, which contains acyclic ureide, an isosteric group of CNS depressant drugs common structure. The study was carried out by modifying the structure of benzoylthiourea using the Topliss model based on the enhancement of its lipophilic and electronic properties. It is predicted that the product will give higher activity than the parent compound. In this study, identification of CNS depressant, anticonvulsant and neurotoxicity effects of the compound synthesized, i.e. 4-chlorobenzoylthiourea, was conducted. The identification of CNS depressant effects was done using Barbiturate Sleeping Time, the identification of anticonvulsant effects was done using Maximum Electroshock Seizure and the identification of neurotoxicity effect was done using rotarod in mice (Mus musculus). This study used five groups of mice: a control group, a standard group (Phenobarbital Na) and 3 treatment groups with doses of 15 mg/kg, 45 mg/kg and 75 mg/kg respectively. From the results, it can be concluded that 4-chlorobenzoylthiourea gives the best CNS depressant, anticonvulsant and neurotoxicity effects at the doses of 75 mg/kg, 15 mg/kg and 45 mg/kg respectively.
PROSES PENGELOLAHAN MENINGKATKAN AKTIVITAS HIPOLIPIDEMIK JAMUR TIRAM (PLEUROTUS OSTREATUS) PADA TIKUS (RATTUS NORVEGICUS) SPRGUE-DAWLEY HIPERKOLESTEROL
No full textOyster mushroom is considered to have hypocholesterolemic and hypolipidemic activities. Therefore, it is classifiedas functional food. Prior to serving and consumption, oyster mushroom can be processed in various ways. Thisresearch studied the effect of three kinds of processing commonly used in cooking oyster mushroom; boiling,frying, and roasting. Thirty Sprague-Dawley male rats, 8 weeks old, were acclimated to laboratory condition,and then induced with high lipid diet. The rats were divided into five experiment groups; high-lipid diet (K),high-lipid diet + raw oyster mushroom (M), high-lipid diet + fried oyster mushroom (G), high-lipid diet + roastedoyster mushroom (P), and high-lipid diet + boiled oyster mushroom (R). Blood samples were obtained from orbitalplexus after acclimation, hypercholesterolemic induction, and 21 days of feeding. The blood serum was examinedfor total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-c), dan high-densitylipoprotein cholesterol (HDL-c). The result showed that cooked oyster mushroom had better hypocholesterolemicand hypolipidemic activity than raw oyster mushroom. Among the three, the roasted oyster mushroom reduced thetotal cholesterol the most, while boiled oyster mushroom reduced triglyceride the most

PENGARUH TEKANAN PISTON PADA PENGATURAN KATUP SOLENOID PROPORSIONAL DUA ARAH TERHADAP LAJU ALIRAN AIR PADA SISTEM KALIBRASI PISTON PROVER OT-400
No full textIn 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 PS
