A Wilkinson Power Divider with Harmonic Suppression and Size Reduction using High-low Impedance Resonator Cells

A miniaturized Wilkinson power divider using high-low impedance resonator cells are designed and fabricated. The proposed power divider occupies 23.7% of the conventional structure circuit area at the operating frequency of 0.9 GHz and it is also able to suppress harmonics. According to the measured results at 0.9 GHz, the insertion-losses of output ports are 3.087 dB, the return-losses at all ports are more than 30 dB, and the isolation between output ports is better than 35 dB. Also, 2nd to 10th spurious frequencies are suppressed. According to the measured S11, when it is less than -15 dB (from 0.65 GHz to 1.1 GHz) the fractional bandwidth of the proposed structure is 50%. Good agreement between simulation and measured results is achieved

Komunikasi Keluarga untuk Menumbuhkan Motivasi Sembuh pada Anak Penderita Kanker

Hasil Riset Kesehatan Dasar tahun 2013 (Riskesdas) menunjukkan prevalensi kanker anak umur 0-14 tahun terjadi pada sekitar 16.291 kasus. Sementara jenis kanker yang paling banyak diderita anak di Indonesia adalah leukemia dan kanker bola mata (Retinoblastoma). Pada lebih dari 50 persen kasus kanker pada anak, anak penderita kanker datang ke fasilitas kesehatan sudah dalam keadaan stadium lanjut. Minimnya pengetahuan orang tua tentang kanker, menjadi salah satu penyebab kanker tidak terdeteksi sejak dini. Padahal apabila dapat terdeteksi secara dini, kanker pada anak dapat disembuhkan dengan pengobatan dan terapi yang baik (Pusat Data dan Informasi Kesehatan, 2015). Penelitian ini membahas mengenai bagaimana komunikasi keluarga untuk menumbuhkan motivasi sembuh pada anak penderita kanker. Penemuan sebelumnya menemukan anak dengan kanker yang menjalani kemoterapi merasakan kecemasan dan kegelisahan yang cukup tinggi. Mereka cenderung mengalami depresi, penarikan diri dan stress sosial. Untuk itu perlu adanya dukungan dari orang disekitarnya. Penelitian ini menggunakan metode fenomenologi yang memahami fenomena dari kehidupan pelakunya. Teori yang digunakan adalah Teori Verbal dan Non verbal, dan Teori Komunikasi Kesehatan. Penelitian dilakukan pada tiga orang tua yang memiliki anak kanker berumur 0-14 tahun dengan lama menderita kanker ˂1 tahun, ±1 tahun dan ˃1 tahun. Hasil penelitian ini menunjukkan bahwa komunikasi keluarga yang dilakukan oleh orang tua yang memiliki anak dengan penyakit kanker untuk membangkitkan semangat dan menumbuhkan motivasi anak agar dapat sembuh dari penyakit yang dideritanya. Orang tua memiliki kemampuan berkomunikasi yang baik, baik itu komunikasi verbal maupun noverbal yang sangat penting dan dibutuhkan dalam perawatan agar dapat mengurangi rasa cemas, takut dan sedih anak yang menderita kanker. Orang tua melakukan komunikasi verbal dan non verbal seperti mencium, memeluk, menggendong, bercerita, bernyanyi dan bermain bersama untuk dapat mengalihkan perhatian anak yang menderita kanker dari rasa sakit dan membuatnya lebih bersemangat. Komunikasi dengan keluarga dan komunikasi dengan lingkungan sekitar termasuk dokter dapat memberikan referensi pada orang tua untuk mengetahui cara perawatan anak yang menderita kanker dengan baik. Melalui komunikasi yang dilakukan oleh orang tua bisa membangkitkan semangat dan motivasi anak untuk dapat sembuh dari penyakit kanker yang dia derita. Hal ini dilakukan dengan cara memberikan nasehat,mengucapkan kata-kata yang baik dengan lembut dan memberikan kata-kata yang bernada semangat pada anak

Effect of Current Frequency and Annealing on Magnetic Properties of [Co70Fe30]97Sn3 Nanowire Arrays

[Co70Fe30]97Sn3 alloy nanowire arrays have been fabricated by alternative current (ac) electrodeposition of Co2+, Fe2+ and Sn2+ into anodic aluminum oxide (AAO) templates. The samples were deposited at current frequency 50, 100, 200, 300, 400, 500, 800 and 1000 Hz, respectively. The structure and magnetic properties of [Co70Fe30]97Sn3 nanowire arrays dependence on different current frequency were analyzed by XRD and alternating gradient field magnetometer (AGFM). The X-ray diffraction patterns are shown an amorphous structure of the[Co70Fe30]97Sn3 nanowires.

A genre analysis of reprint request emails written by EFL and physics professionals

The present study aimed to analyze reprint request e-mail messages written by postgraduates (MA students) of two fields of study, namely Physics and EFL, to realize the differences and similarities between the two email types. The results showed that the two corpora were much alike at the level of move schemata while there were some differences concerning strategies and microstructural features. The results showed that the two corpora were much alike at the level of move schemata while there were some differences concerning strategies and microstructural features. The email writers within each discipline were affected by their previously learned texts and the physics group was affected by the conventions of Persian letter writing.

Penerapan Model Pembelajaran Think Pair Share dalam Upaya Meningkatkan Hasil Belajar IPS Sejarah Siswa Kelas VII C SMP Alkaromah Aidarusy Kecamatan Koto Kampar Hulu Kabupaten Kampar Tahun Ajaran 2015/2016

This research is motivated by the low learning outcomes of students ofclass VII C SMP Alkaromah Aidarusy on History Lesson IPS. The results of studentlearning is still low and does not reach the specified KKM is 70. This is partly due tothe methods used in the study are less precise IPS. The purpose of this study was todetermine the application of learning model Think Pair Share and know the learningoutcome IPS History class VII C SMP Alkaromah Aidarusy through the implementationof learning model Think Pair Share. This research using method classroom actionresearch, which lasted for two cycles. Research action plan, starting from planning,implementation, observation, and reflection. Subjects numbered 18 people. Collectingdata using tests and observation. Data were analyzed by looking at the activity ofteachers and students as well as absorption and mastery learning students bothindividual and classical. The results showed that the learning model Think Pair Sharelearning model can improve the learning process and improve student learningoutcomes. This is evidenced by the increased activity of teacher and students in cycle Iand II. Besides, the learning outcomes of students also increased from indigo pre PTK,cycle I and cycle 2

Pemanfaatan Pupuk Organik Cair terhadap Pertumbuhan dan Hasil Beberapa Varietas Tomat (Lycopersicum Esculentum L.)

. The study was to determine the variety and concentration of Enviro Plus (liquid organic fertilizer) that have best growth and yield of tomatoes, and as well as interaction of both factors. Randomized Block Design was used with pattern 3x3 factorial with three replications. There were two factors, varieties (Permata, Montero and Niki) and concentration of Enviro Plus (0.5, 1.5, and 2.5 cc L-1) of water. The results showed that the varieties had significant effect on plant height umur 15, 30 and 45 day after planting (DAP) , the number of flowers per stalk at age 37 DAP, the number of fruits per plant age 57 DAP and a total weight of fruit per plant. The best growth and yield found on Niki varieties. Concentration of Enviro Plus that have significantly affect on stem diameter and the at age 15 DAP, total weight of fruit per plant. The best growth and yield found at concentration of Enviro Plus 0.5 cc L-1 of water). There were no significant interaction effect between variety and concentration of Enviro Plus on growth and yield of tomato

Pengaruh Varietas dan Dosis Pupuk SP-36 terhadap Pertumbuhan dan Hasil Tanaman Kacang Tanah (Arachis Hypogaea L. )

. This study aimed at finding the best varieties and the right dosage of SP-36 fertilizer and the interaction of both factors on the growth and yield of peanut crops. The research was conducted in the village of Darussalam-Banda Aceh, from August to November, 2009. Experimental design was used in this study with Randomized Block Design patterns of 3 x 3 factorial with three replications. Two factors investigated were varieties (Gajah, Kuala Batee, dan Kelinci), and applied dosages of SP 36 fertilizer (100, 150 and 200kg ha-1). Variables observed in the study were plant height and number of branches per plant, the number of pods per plant, the number of empty pods per plant, total number of pods per plant, weight of pods per plant, dry weight of 100 seeds, dry seed weight per plot and the net weight of dried beans per hectare. The results showed that the varieties have a effect on plant height, pods number per plant, number of pods per plant and the total weight of 100 dry seeds. Best growth and results were found in varieties of gajah. Dose of fertilizer has a real effect on plant height. A better result was found in SP-36 of 150 kg ha-1
