Abstract

Heat pump is a device that can be make heat and cool , which is functions as a cooling evaporator can be replaced to be a heating condenser. With adding a heat exchanger in the heat pump can provide better effect of heating and cooling. In this experiment, the heat pump using type hydrocarbon refrigerantand type friendly refrigerant to the environment, one of refrigerant isR-290. From the results that obtained value Coefficient Of Performance (COP) in the heat pump that uses a counter flow heat exchanger is 4.8 while the heat pump that does not use a counterflow heat exchanger obtained COP of 4.1. Efficiencies increase in the heat pump without using counter flow heat exchanger is 74%, otherwise the efficiency decrease of the heat pump using heat pump is 85%.

Abstract

In generally cooling hydronic system applied to large-scale commercial or industrial use, where water cooling is processed through heat transfer mechanism in the evaporator pipe using a vapour compression system such as a chiller with refrigerant. The research idea is based on not available practice test of cooling hydronic system at the Department of Refrigeration and Air Conditioning Engineering at State Polytechnic of Indramayu which is the main competency in the course of Air Conditioning Applied. As teh utilization practice made cooling hydronic system by utilizing a vapour compression system that is split AC using refrijeran R32 is environmentally friendly. The split AC system modifies its evaporator coil into a heat exchange medium to cool water in the water tank. The cold water is then distributed in the piping installation system with the two pumps that are varied in series and parallel. From this process, it is necessary to know the working capability of the pumps in terms of its characteristics (head and capacity) or its performance, including energy losses and cooling capacity system. The results obtained are analyzed and the calculation is in accordance with theoretically known study.

Abstract

Akhir-akhir ini sering terjadi kebakaran yang disebabkan oleh beberapa faktor termasuk faktor kelalaian manusia. Proses datangnya kebakaran selalu tanpa dapat diprediksi terlebih dahulu. Umumnya kebakaran diketahui apabila keadaan api sudah mulai membesar atau asap sudah mengepul keluar dari gedung itu. Pada penelitian ini dilakukan perancangan alat, mencari komponen serta mendesain pendeteksi kebakaran dari komponen-komponen yang ada sehingga alat akan bekerja lebih maksimal. Pada tahap ini juga melakukan pembuatan algoritma dan juga software. Hasil penelitian menunjukkan bahwa prototipe sistem pendeteksi kebakaran yang dirancang dapat mendeteksi kebakaran berdasarkan informasi dari sensor api  dan gas, dan mengaktifkan buzzer sebagai indikatornya yang akan berbunyi.

ABSTRACTNutritional problems in school children need to be given serious attention. Impact of nutritional problems in school children can affect motor skills and academic achievement. The purpose of this study was to determine The Correlation of family members, maternal nutrition knowledge and level of energy consumption with nutritional status of elementary school children. Cross sectional study was conducted, the sample totaled 84 students. A total of 51.2% of families have a large number of members, as many as 65.5% of mothers have sufficient knowledge of nutrition, as many as 85.7% had levels less energy consumption and as much as 65.5% had normal nutritional status. The analysis was performed with Spearman Range test. There is a correlation between level of energy consumption and nutritional status (p = 0.001), there was no association of family members (p = 0.244), maternal nutrition knowledge (p = 0.115) with the nutritional status of school children. Suggestions to do school feeding to increase the level of consumption and nutritional status.Keywords: Elementary School Children, Nutritional status, Energy Consumption Kesmasindo, Volume 8, Nomor 2, Juli 2016, Hal. 44-51

Abstract

ABSTRACTThe risk of School children in Iodine Deficiency Disorders (IDD) endemic areas will decrease of learning achievement . Objective of this study was to analyze the status of IDD and health aspects associated with school children's learning achievement base IDD in endemic areas .The method was used a cross-sectional approach . Population of this study were all Rempoah primary school children, there are 178 children , while the samples were taken by purposive sampling of 33 fourth grade students at SDN I Rempoah Baturaden . The results showed all samples of students there were no have an enlarged thyroid gland through a large palpasi. Although Chi Square analysis test showed no relationship in all variables, but using cross tabulating we can see which samples who have genetic family of IDD have low good learning achievement (66,7 %) than none (84,6 %), samples who have poor nutritional status have low learning achievement (57,1 %) than good one (84,6 %) and samples who have low physical fitness have low good learning achievement(75,9 %) than good physical fitness (100 %) . Suggested more activity level for increase physical fitness .Keywords : IDD, Nutritional Status, School Children Kesmasindo, Volume 7(2), Januari 2015, Hal. 71-81

Abstract

ABSTRACT   The physical freshness have to be applied among the children between 6 - 12 years old. At that years, the children can do all the activities optimally and confidently. Hence, the influence factors included are : gender/sex, nutrition and physical activities. Analytical study used by the research by cross sectional method. Gathering the samples done by purposive sample technique. The samples are from 33 students, which is the students from grade VI state elementary 1 Rempoah, Baturaden District. Analytical data include of chi-square test to analyze the relation between gender/sex, nutrition status and physical activities with the physical freshness to children (p<0,05). The result of the study showed that there is the correlation between physical activities (p= 0,014) to the children and there is not correlation between gender/sex (p= 0,550), nutrition status (p= 0,649) and physical freshness to the children. Hopefully, the next researcher can do the research not only by the factors of gender or sex, physical activities and nutrition status but also, from the other factors can be influence.   Keyword : gender, nutrition status, physical activity, physical freshness, elementary school student.  Kesmasindo, Volume 7( 1) Juli 2014, Hal 31-38

Abstract

School age children 6-12 years require attention to meet the needs of nutrients in the body to achieve a balanced nutritional status. In addition to nutritional status, physical activity is also needed to increase physical activity by the bodyin order to perform daily activities. The difference of geographical location of domicile has an influence on eating patternand daily activities. This research aimed to know the difference of nutritional status and physical fitness level between rural and urban elementary school children in Banyumas district. The type of research used was descriptive quantitative with cross-sectional approach. Sampling used purposive sampling technique. Sample used was 52 students of class V elementary school. The data analysis used Independent sample t-test. Result showed category overweight of nutritional status for children in rural (11.5%) was lower than children in urban(38.5%). Conversely, physical fitness levelfor children in rural (57.7%) was higher than children in urban(15.4%). Conclusion: there were differences in nutritional status (p=0.02) and physical fitness level (p=0.00) on elementary school children in rural and urban areas. Suggestion: students are expected to increase physical activity outside of school hours in order to obtain good physical condition
