Application of digital control to a magnetic model suspension and balance model

The feasibility of using a digital computer for performing the automatic control functions for a magnetic suspension and balance system (MSBS) for use with wind tunnel models was investigated. Modeling was done using both a prototype MSBS and a one dimensional magnetic balance. A microcomputer using the Intel 8080 microprocessor is described and results are given using this microprocessor to control the one dimensional balance. Hybrid simulations for one degree of freedom of the MSBS were also performed and are reported. It is concluded that use of a digital computer to control the MSBS is eminently feasible and should extend both the accuracy and utility of the system

Reaksi Pasar Modal Indonesia Terhadap Pemilu Legislatif 2014 Pada Indeks Lq45 Di Bei

This study aimed to find the significant difference of abnormal return in stock Index LQ45 before and after the legislative election in 2014. This study used saturation sampling from stock index LQ45 that was registered during the period from February to July 2014. The data analysis technique used was a different test in pairs, and the window periods used were 7 days before and 7 days after the course of legislative election in 2014. The results of this study found that there was no significant difference before and after the legislative election. Based on the results, it is shown that market was not in the form of half-strong market in terms of information, which means it did not react toward the occurrence of legislative election in 2014, as the investors had predicted that the results of Legislative Election 2014 were not much different from the information obtained from the survey agency which was conducted prior to Legislative Election 2014

Penggunaan Aplikasi Sistem Informasi Geografis dalam Pemetaan Persebaran Pemberi Pelayanan Kesehatan Tingkat Pertama dalam Rangka Persiapan Penyelenggaraan Sistem Jaminan Sosial Nasional di Kota Denpasar

To achieve health coverage for all citizen of Indonesia, the government has launched a socialinsurance namely Sistem Jaminan Sosial Nasional (SJSN) which will be implemented in 2014.In the social insurancePemberi Pelayanan Kesehatan tingkat I, PPK I, have a central role as gatekeeper. This study purposed to gain information about the distribution of PPK I in the capital cityof Bali Province and assessed need level PPK I of Bali. The distribution and need level of PPK Ican be seen using Geographic Information System (GIS).This research was a cross-sectional descriptive study. Population and sample in this researchware all PPK I which registered in PT. Askes (Persero) and all of population in Denpasar.GIS analysis showed that PPK were not evenly distributed. PPK I distributed mostly in the centreof Denpasar. Based on cluster map can be seen that the highest clustered PPK I located in centreand West Denpasar area.PPK I need level map showed the mosted needed area was Pemogan village. PPK I need levelmap can be used by PT. Askes (Persero) to determine the PPK I need level in Denpasar city. It willbe easier for PT. Askes (Persero) to determine priority of distribution of PPK I

Analisis Gangguan Sistem Transmisi Listrik Menggunakan Metode Root Cause Analysis (Rca)

Public lifestyle nowdays is very dependent on the availability of electrical power and PT. PLN. (PERSERO) is the sole provider of electricity in Indonesia. Data PT. PLN (Persero) P3BS showed an increase in the frequency and duration of electrical transmission systems disorders owned by PT. PLN (Persero) in Sumatra with a loss of energy can not be served reach 10682.24 MWh. This study uses the Root Causes Analysis (RCA) to find the root cause of the electrical transmission systems disorders owned by PT. PLN (Persero) in South Sumatra. Understanding the root causes of electricity transmission system disorders will generate appropriate recommendations to prevent recurrence of similar disorders. From the fault tree analysis results obtained twenty one root cause of the transmission system disorders, some of which are: the fault current is greater than the ability of the tool to neutralize the fault current, conductor corrosion caused by polution and climate demage, lack competency of installation crew, lack of coordination with the surrounding community, and the field inspection findings are followed late. Some of the root causes corrective recommendations include: doubling the number of transmission lightning arresters installed at critical points of a lightning strike, replacing the Aluminum conductors reinforced with steel (ACSR) with Aluminum Conductor Composite Core (ACCC), approach to the surrounding community, a faster response of the field findings, and improving the competence of installation crew

Factors Associated With Overweight/obesity Among Adults In Urban Indonesia

Overweight/obesity is increasing in developing countries, including Indonesia, being more prevalent in urban than rural areas. Understanding about associated factors of overweight/obesity is important for intervention purposes. The study objective was to assess factors associated with overweight/obesity in urban Indonesians. This cross-sectional study involved primary data collection among 864 adults aged 18-45 years in five major urban cities of Indonesia. Weight, height, waist and hip circumference were measured, and overweight/obesity was defined as BMI>25 kg/m2. Factors associated to overweight/obesity was ellicited by logistic regression. The study showed that proportion of overweight/obesity was significantly higher among women than men (42.8% and 29.2%). Median total energy intake was 1974 kcal/day, and median fat intake was high (75.3 g; 25th-75th percentile: 49.6-109.4 g). More than 70 percent of subjects consumed high energy dense food/beverages often. Only around 27 percent of the subjects had high intensity physical activity/PA level and more than 50 percent spent >6 hours using TV/computer, indicating low PA level. After adjusting for confounders, often consumption of high energy dense food consistenly showed association, although not signficant, with overweight/obesity. Moreover, men with higher sedentary activities indicated by TV/computer USAge >6 hours/day and women with less days of performing vigorous PA had 1.4 and 3 times higher odds to become overweight/obese, respectively. Thus, overweight/obesity prevention should focus on reduction of consumption of high-dense energy food, including fat intake; coupled with increasing PA level by having more days of vigourous recreational PA and reduction of TV/computer USAge, especially among married older urban adult
