Hubungan Pengetahuan Dan Sikap Dalam Memilih Makanan Jajanan Dengan Obesitas Pada Remaja Di SMP Negeri 2 Brebes

Latar belakang : Pengetahuan berpengaruh terhadap sikap dalam memilih makanan jajanan. Pengetahuan yang baik diharapkan mempengaruhi konsumsi makanan yang baik sehingga dapat menuju status gizi yang baik pula. Kurang cukupnya pengetahuan tentang gizi dan kesalahan dalam memilih makanan jajanan akan berpengaruh terhadap status gizi seperti obesitas. Penelitian ini bertujuan untuk mengetahui apakah terdapat hubungan antara pengetahuan dan sikap dalam memilih makanan jajanan dengan obesitas di SMP Negeri 2 BrebesMetode: Jenis penelitian ini adalah penelitian observasional dengan rancangan cross sectional. Subyek penelitian ini adalah remaja kelas VII-IX di SMP Negeri 2 Brebes. Pengambilan sampel sebanyak 66 anak dilakuan dengan simple random sampling. Data yang dikumpulkan meliputi pengetahuan dan sikap dalam memilih makanan jajanan yang diperoleh berdasarkan hasil wawancara dengan kuesioner, dan perhitungan IMT berdasarkan hasil pengukuran berat badan dan tinggi badan. Uji normalitas menggunakan Kolmogorof- Smirnov. Data berdistribusi tidak normal pengujian menggunakan uji korelasi Chi-Square.Hasil:. Hampir seluruh responden memiliki pengetahuan baik yaitu sebanyak 63 orang (95,5%), dan memiliki sikap yang baik sebanyak 57 orang (86,4%). Subyek dalam kategori non obesitas sebanyak 50 orang (75,8%), pre obesitas sebanyak 7 orang (10,6%), dan obesitas sebanyak 9 orang (13,6%). Uji statistik menunjukkan tidak terdapat hubungan yang bermakna antara pengetahuan dan sikap dalam memilih makanan jajanan dengan obesitas pada remaja (p>0,05)Simpulan: Tidak terdapat hubungan yang bermakna antara pengetahuan dan sikap dalam memilih makanan jajanan dengan obesitas pada remaja di SMP Negeri 2 Brebes

Analisa Kebutuhan Kapasitas Kapasitor Bank untuk Menjaga Pasokan Tegangan Operasi pada Bus Pompa Motor HCT Duri

PT. Chevron is one of the largest oil companies in the world. To be able to do maximum production, PT. Chveron need to make sure all goes well with the production facilities. One of the important production facilities is the delivery pumping motor. Duri operation area has 7 pumping motors to be installed with capacity of 550HP each of them. Each of individual pumping motor requires 4,16 kV which supplied by 13,8 kV of distribution network Prior to the installation, it is necessary to have a study to anticipate drop voltage or overvoltage case. This paper proposes capacitor banks installation approach. The approach uses several trial errors in the placement of capacitor in the respective bus within distribution network. The ETAP simulation result shows 4 buses with following configuration i.e bus 1 and bus 2 with 600 kVar, in the other case bus 3 and bus 4 with 300 kVar

Analisis Keragaman Morfologi dan Biokimia pada Anggrek Phalaenopsis (Orchidaceae)

Phalaenopsis orchid is one of famous genera in Orchidaceae family which have high economic value. Phalaenopsis breeding needs to be developed intensively to fulfill market demand for new varieties. The objective of this study was to obtain the information of morphological and biochemical diversity of a collection of Phalaenopsis orchid which will be useful for Phalaenopsis breeding. Plant materials used were 10 genotypes of Phalaenopsis with various petal colours of white, yellow, pink, deep pink, purple, or combination of yellow and brown. Morphological diversity of 10 genotypes were analyzed based on qualitative and quantitative characters following UPOV guidance for Phalaenopsis, while biochemical diversity was based on pigment content such as chlorophyl, anthocyanin, and carotene in plant roots, leaves and flower petals. The result of this research showed morphological diversity of 10 genotypes used was relatively high, with similarity of 55%. In that level of similarity, genotypes were grouped into two cluster. Biochemical analysis showed that most of genotypes were different for anthocyanin and carotenoid content for each plant organ. Genotype which showed high content of anthocyanin in leaves was Phal. hybrid ‘PH37' while high content of carotene in leaves was Phal. hybrid ‘PIROUI. High content of anthocyanin in petals were found in Phal. hybrid ‘PH37' and Phal. esmeralda, and high content of carotene were in Phal. cornucervi and Phal. cornucervi Red. Root with high anthocyanin content was found in Phal. hybrid ‘PIROU1'. There were significant correlation (0.975) for anthocyanin content between leaves and petals, petals and roots (0.953) on Phal.hybrid ‘PH37', and between leaves and roots (0.874) on Phal. hybrid ‘PIROU1)

Perancangan Transformator Satu Fasa dan Tiga Fasa Menggunakan Perangkat Lunak Komputer

The transformer is widely used, both in the field of electricity and electronics. Use of the power system allows choosing the appropriate voltage and economical for each purposes. To obtain a good and satisfying design it is necessary to use computer software in design process. The design of single phase and three phase transformer with the help of computer software is intended to replace the conventional process which is done manually so as to improve the efficiency of time and energy. In this research, we use visual basic 6.0 as a program language and the golden ratio (1 : 1,618) is used as the ratio between the width and thickness of the iron cor

Analisis dan Pemodelan Motor Induksi Tiga Fasa Delapan Kutub dengan Rangkaian Ekivalen Invers Г

This study aimed to analyze and modelling an induction motor. The motor is used in this study is three phases induction motor eight poles, 500 W, 30 V, 50 Hz and 750 rpm. In this study the equivalent circuit is form into an inverse Г transformation equations of three phases induction motor. The porpose of this study is to create a model of three phases induction motor eight poles using inverse Г equivalent circuit, analyzing equations and equivalent circuit models obtained using matlab application, and comparing the results with the results of the actual testing analyst induction motor three phases eight poles.Analysts done on two conditions, no load and load. From direct testing and analysis results were found comparisons percent error of the test results and analysis of induction motor three phases eight poles, there are input voltage when starting is 11%, starting current 23,21%, the influence load to voltage is 2,9%, the effect of load on the starting current 24,3% and during the current reduce is 26%. The percent error is quite high, this is cause errors in measurement parameters
