At the time of this printing companies both small to large are faced with the challenge of globalization and the MEA, coupled with the conditions of the economic downturn in Indonesia in 2016, this has an impact on the level of business competition business increasingly high, therefore employers can determine the right strategy in developing their business and increase revenue is a company that can achieve its goals more efficiently in the future.Research conducted in the printing business EMJ Productions is a survey research. Survey research is research that takes a sample from a population with a list of questionnaire as the main data collectors in the field. Key informants and respondents were obtained by snowball method, namely the acquisition of the target individual interviews based on information from key informants and respondents before. Thus since the beginning of unspecified number of individuals targeted interviews, but more emphasis on completeness and eligibility information obtained to capture the general trend of the business development strategy of printing EMJ Productions. Study period for 6 months, starting in April-September, 2016

The purpose of this study was to describe efforts to form Islamic character of youth with jam'iyah diba'iyah activities in Pagerwangi Village which included variables (1) teenage character, variable (2) jam'iyah diba'iyah. This research applies the mix methods method. The subjects in this study include members, alumni, Jam'iyah diba'iyah supervisors. The quantitative data instrument in this study used a questionnaire, while the qualitative data collection used observation data along with interviews. The sample in this research is 20 respondents. The data obtained were analyzed using a percentage descriptive method. The results of the questionnaire data research stated that the percentage of the implementation of jam'iyah diba'iyah activities was 81.25%, while the percentage of youth members of jam'iyah diba'iyah was 79.625%. And it is known that the success rate of forming Islamic character through jam'iyah diba'iyah activities shows a percentage of 80.4375% which means very good. As for efforts to form an Islamic character in jam'iyah diba'iyah activities in Pagerwangi village, namely through habituation both in organizing, socializing, and behaving, setting an example according to the characteristics of the Prophet, giving mauidzah hasanah and giving educational warnings and punishments

The land use in Argopuro Mountain is very diverse but not much information on the existence of wildlife, especially bird species that important role in helping the regeneration of natural forests and has not been documented its existence. The purpose of this study to determine the diversity of bird species in some land use around the area of Mount Argopuro. Data collection of species and number of birds using stratified systematic sampling with point counts method on each land use planted forest, protected forest, mountain rainforest, savanna and pine forest in the area of Argopura Mountain. Data analysis was done to calculating the diversity index of Shannon bird species. Medium index diversity of bird species was found in planted forest (2.6) and protected forest (2.48); the lowest in the pine forest (1.64), the mountains rainforest (1.96) and savanna (0.68).

Teknologi proses produksi hidrogen secara termokimia telahmenjadi unggulan bila dikopel dengan reaktor nuklir temperatur tinggi. Proses ini hanya memerlukan energitermal untuk memecahkan air menjadi hidrogen dan oksigen. Implementasi rancangan eksperimen reaksiBunsen telah dilakukan. Bahan peralatan percobaan ini terdiri dari bahan kaca pyrex dan pipa teflon agar tahanterhadap serangan korosi, tekanan 2 bar dan suhu reaksi 120 oC. Percobaan telah dilakukan dengan parameterpengubah yaitu durasi reaksi, komposisi I2 dan H2O, sedangkan parameter tetap yaitu komposisi SO2,temperatur dan tekanan gas SO2 secara statis. Hasil percobaan optimasi dengan kondisi menunjukkan bahwaproduk reaksi Bunsen meningkat dengan bertambahnya fraksi I2, H2O dan durasi reaksi. Namun padapenambahan H2O peningkatan produk terbatas pada jumlah H2O 0,055 mol. Hasil analisis terhadap produkreaksi Bunsen menunjukkan bahwa reaktan yang bereaksi membentuk produk adalah sebesar 5,6 % dan reaktanyang belum bereaksi akan terus membentuk produk reaksi selama produk reaksi yang terjadi dipisahkan darireaktan.

PENENTUAN KAPASITAS PRODUKSI HIDROGEN DARI PERENGKAHAN AIR BERDASARKAN DISTRIBUSI KALOR RGTT-KOGENERASI. Hidrogen adalah molekul penting untuk energi dan pangan. Penggunaan hidrogen untuk energi dapat mengatasi sekaligus dua masalah, yaitu susutnya cadangan bahan bakar minyak dan pemanasan global. Di bidang pangan, hidrogen dibutuhkan sebagai bahan baku pembuatan amonia untuk pupuk nitrogen. Senyawa yang mengandung hidrogen dengan kelimpahan tinggi dan murah adalah air. Sumber energi primer diperlukan untuk merengkah molekul air dan menghasilkan hidrogen. Sumber energi potensial untuk tujuan tersebut adalah nuklir. Melalui sistem kogenerasi, reaktor nuklir gen-IV (generasi IV) merupakan sumber kalor strategis untuk produksi hidrogen dari air karena sifat gen-IV yang berkelanjutan dan mampu menghasilkan kalor temperatur tinggi dengan sistem keselamatan melekat yang andal. Tujuan makalah ini adalah menentukan kapasitas produksi hidrogen dari perengkahan air berdasarkan distribusi kalor RGTT (Reaktor berpendingin Gas Temperatur Tinggi) Kogenerasi. Dua teknik termokimia perengkahan air, yaitu siklus-SI (Sulfur-Iodium) dan siklus-I (Iodium) disimulasikankan dengan Aspen HYSYS. Hasil simulasi menunjukkan bahwa kalor 200 MW dari RGTT200K yang teralokasikan untuk produksi hidrogen adalah 59 MW. Daya kalor tersebut setara dengan laju produksi hidrogen 683 kg/jam (siklus-SI) atau 1.054 kg/jam (siklus-I). Siklus-SI dan siklus-I berada pada tahap pengembangan skala laboratorium dan ditujukan untuk produksi hidrogen dari air dengan energi nuklir tanpa pasokan gas alam.Kata Kunci : hidrogen, energi, pangan, reaktor nuklir, kogenerasi

Background: The incidence of depression in adolescents can be very dangerous because it can affect learning in the school. To neutralize the incidence of depression in adolescents, we can apply good social support from family, friends, and the environment so the teenager can pass it well. The purpose of this study was to determine the correlation between social support and depression in female student of 12th class Al Islam 1 Senior High School Surakarta. Methods: This study is an observational study with cross sectional analytical conducted in July 2014 in Al Islam 1 Senior High School Surakarta. Sampling is conducted for all of the female students of 12th class, and then exclude sample that cant be inclution and exclution criteria. Correspondent filling: (1) the contents of personal data; (2) L-MMPI questionnaire; (3) ISEL questionnaire to assess the social support scores; (4) BDI Questionnaire to assess depression scores. The data were obtained for 143 students and were analyzed using Spearman through 21.00 SPSS for Windows. Results: The analysis showed Spearman correlation coefficient -0.880; p = 0.000. The strength of the correlation values ??included in the category of very strong (r = 0.8-1.00). p > 0.05 it can be concluded that H1 is accepted and Ho is rejected or suggest a correlation between social support and depression in female student of 12th Class Al Islam 1 Senior High School Surakarta. It also showed the negative direction of correlation. It means that the higher of social support, then lower the depression, and the lower of social support, then higher the depression. Conclusions: There is correlation between social support and depression in female students of 12th class Al-Islam 1 Senior High School Surakarta. The correlation is very strong with the negative direction of correlation means that the higher of social support, then lower the depression, and the lower of social support, then higher the depression. Keywords: Adolescence, social support, depression
