Hubungan antara Sanitasi Rumah dan Perilaku dengan Kejadian Pneumonia Balita

Abstract: Penelitian ini bertujuan untuk mengetahui hubungan antara sanitasi rumah dan perilaku dengan kejadian pneumonia balita Ini termasuk penelitian penjelasan dengan rancangan  belah lintang Jumlah sampel sebanyak 79 responden Instrumen berupa kuesioner, rollmeter, dan thermohygrometer Analisis data menggunakan uji chi square Hasil analisis data menunjukkan bahwa sanitasi rumah yang berhubungan dengan kejadian pneumonia pada balita adalah luas ventilasi kamar (p<0,001), jenis lantai (p=0,036), dan kepadatan hunian kamar (p<0,001) Perilaku yang berhubungan dengan kejadian pneumonia balita adalah kebiasaan membuka jendela saat pagi dan siang hari (p<0,001), dan perilaku merokok orang tua (p=0,008)  Abstract The purpose of this study was to determine the relationship between house sanitation and human behavior with the incidence of pneumonia in children under five years This was explanatory research with cross sectional design The samples obtained were 79 respondents The instruments used were questionnair, rollmeter, and thermohygrometer The data were analyzed by chi square test The results showed that house sanitation related to the incidence of pneumonia were the spacious of the room’s ventilation (p < 0,001), floor’s type (p = 0036), and the density of the room (p < 0,001) Behavior associated with the incidence of pneumonia were the habit of window opening during morning and afternoon (p < 0,001), and parental smoking behavior (p = 0008) Keywords: House sanitation; Behavior; Pneumonia

Graphene as a Buffer Layer for Silicon Carbide-on-Insulator Structures

Abstract: We report an innovative technique for growing the silicon carbide-on-insulator (SiCOI) structure by utilizing polycrystalline single layer graphene (SLG) as a buffer layer. The epitaxial growth was carried out using a hot-mesh chemical vapor deposition (HM-CVD) technique. Cubic SiC (3C-SiC) thin film in (111) domain was realized at relatively low substrate temperature of 750 °C. 3C-SiC energy bandgap of 2.2 eV was confirmed. The Si-O absorption band observed in the grown film can be caused by the out-diffusion of the oxygen atom from SiO2 substrate or oxygen doping during the cleaning process. Further experimental works by optimizing the cleaning process, growth parameters of the present growth method, or by using other growth methods, as well, are expected to realize a high quality SiCOI structure, thereby opening up the way for a breakthrough in the development of advanced ULSIs with multifunctionalities.

Pengembangan instrumen tes literasi matematika model pisa

Abstract: Penelitian ini bertujuan menghasilkan instrumen literasi matematika model PISA (Programe International Student Assessment) untuk peserta didik usia minimal 15 tahun atau setingkat siswa SMA kelas X yang teruji kelayakan dan keunggulannya untuk mengukur literasi matematika siswa. Jenis penelitian ini adalah penelitian pengembangan (research and development), dengan model Borg and Gall (2003). Metode pengumpulan data menggunakan angket dan tes literasi matematika model PISA. Data dianalisis dengan analisis deskriptif dan analisis kuantitatif. Hasil penelitian ini adalah : 1) review dari ahli menyatakan instrumen tes literasi matematika model PISA yang berada pada kategori baik. 2) Hasil tanggapan peserta didik untuk aspek keterbacaan pada ujicoba one-to-one sebesar 90, 48% kategori sangat baik. 3) hasil uji validitas butir pada ujicoba luas diperoleh 33 butir valid dengan nilai reliabilitas sebesar 0,918. 4) hasil uji validitas konstruk diperoleh hasil bahwa setiap butir secara signifikan dapat mengukur 7 variabel literasi matematika, yaitu : komunikasi, matematisasi, menyajikan kembali, menalar dan memberi alasan, menggunakan strategi, menggunakan symbol, serta menggunakan alat matematika. 5) model konseptual literasi matematika model PISA yang dirancang berada pada kategori goodf fit dengan nilai RMSEA 0.019, CFI 0,91 dan GFI 1,00. 6) Instrumen tes literasi matematika model PISA Praktis kategori sangat baik dengan nilai sebesar 92%.The aim of this research is develop mathematic literacy PISA Model test for students at least 15 years of age or tenth grade level high school students who tested the feasibility and superiority to measure mathematical literacy. Type of research is research and development by Borg and Gall (2003) model. Methods of data collection is using a questionnaire and mathematics literacy PISA model test. Data were analyzed as descriptive and quantitative analysis. The results are: 1) Review of expert stated that the instrument tes of literacy mathematical PISA models d in good category. 2) the validity of the test obtained extensive trial valid from 33 grains with value of reliability 0.9 18. 3) The construct validity showed that each grain significantly measuring 7 of mathematical literacy variables: communication, matematisasi, restate, give reasoning reason, using strategy, using symbols, and using mathematical tools. 4) Construct validity of the test results also obtain a conceptual model of literacy PISA mathematical models that are designed to be in the category of good fit with a RMSEA by 0.019, CFI by 0,91 and GFI of 1.00. 5) The result of user feedback (teacher) to aspects of practicality as much as 92% with very good category.

IKLIM MIKRO DAN KEBUTUHAN RUANG TERBUKA HIJAU DI KOTA SEMARANG (The Micro Climate and The Need of Green Open Space for The City of Semarang)

Abstract: ABSTRAK Salah satu darnpak perkembangan jumlah penduduk kota adalah terjadinya konversi lahan. Konversi ruang terbuka hijau (RTH) menjadi fasilitas bangunan menyebabkan terjadi pencemaran di kota. Berkurangnya RTH mengakibatkan terjadinya kenaikan temperatur lokal dalam kota. Keberadaan RTH memiliki manfaat cukup besar dalam peningkatan kualitas lingkungan hidup kota, seperti sebagai pengendali iklim mikro. Sebaran vegetasi perindang termasuk kategori jarang, terutama komposisi vegetasi rendah dan kerapatan pohon sangat jarang. Kondisi Iklim mikro secara keseluruhan termasuk kategori sebagian tidak nyaman, khususnya pada siang hari. Kondisi tersebut dipengaruhi oleh kurangnya vegetasi perindang di sepanjang jalan, sehingga kondisi iklim mikro menjadi panas dan kering. Keberadaan RTH di Semarang Tengah yang hanya seluas 6,77% perlu ditambah RTH seluas 14,02%. Diharapkan luas RTH sebesar 20,79% dari total luas wilayah, sehingga akan dapat memperbaiki iklim mikro di kawasan perkotaan. ABSTRACT One of the impact of people growth in town is land conversion. Green open space conversion become building facilities cause contamination in the city. Decreasing of green open space result local temperature increase in the city. Existence of green open space have big enough benefit of the quality of city environment, for example by controller of micro climate. The leafy vegetation spread include categories seldom, especially composition of low vegetation and closeness of tree very rare. Condition of micro climate as categorized 'a part unpleasant', specially in the day time. The condition influenced by decrease of vegetation in alongside street, so that cause situation of micro climate hot and dry. Existence of green open space in Middle Semarang which only for the width of 6.77% require to be added green open space by 14.02%. So that expectedly wide of green open space equal to 20,79% from wide of total region, will be able to improvement of micro climate in urban area.

Analisis Gerak Pointing Pada Olahraga Petanque

Abstract: This study aimed to analyze pointing movement skill of Semarang Petanque athlete. This study was descriptive quantitative design which described systematically facts and characteristics of pointing movement by Semarang Petaque Athlete. The pointing movements as data were descriptive. This analysis used descriptive statistic which measured frequency. This data was taken from Biomechanics aspect of 3 pointing movements of Petaque by 8 men and women players of Semarang city. They were; (1) holding a boule, (2) foot position, and (3) throwing the boule. The measurement was carried out by two national coaches and one international coach of Petaque. The result shows that; 1) the average value of holding a boule is 4.4 or 88% of percentage which categorized as very good, 2) the average value of foot position is 4.6 or 92% of percentage which categorized as very good, and 3) the average value of throwing a boule is 3.72 or 74.4% of percentage which categorized as good. Overall movements point out good category with 88% of percentage.
