Analisis Sektor Basis dan Non Basis di Provinsi Nanggroe Aceh Darussalam

The study was conducted to identify basic sectors and non basics, and to identify thegrowth of basic and non basic sector from 1992 – 2001 in the Provinsi Nanggroe AcehDarussalam. The data were collected from Badan Pusat Statistik (BPS) and others publishedliteratures regarding to this study. Location Quotient (LQ) and Compounding Factor Analyseswere applied in the study. The results of the study shows that from nine sectors it was knownthat mines sectors, processing industry and agriculture sector are the basic sectors.Meanwhile, others sectors are the non basic sectors. In addition, the study revealed that thegrowth of the basic and the non basic sectors from 1992 – 2001 are fluctuated

Analisis Kesalahan Penggunaan Ejaan Dalam Karangan Narasi Siswa Kelas X SMA Swasta Taman Siswa Binjai Tahun Pembelajaran 2016/2017

Penelitian ini bertujuan untuk mendeskripsikan dan mengklasifikasikan bentuk kesalahan penggunaan ejaan yang terdapat dalam karangan narasi siswa kelas X SMA Swasta Taman Siswa Binjai tahun pembelajaran 2016/2017, mendeskripsikan kesalahan ejaan yang paling dominan dilakukan siswa dalam karangan narasi yang diproduksi tersebut. Penelitian ini menggunakan pendekatan deskriptif kualitatif. Hasil penelitian ini adalah sebagai berikut. Pertama, Jumlah kesalahan penggunaan ejaan yang terdapat dalam karangan siswa mencapai 945 (17,67%) kesalahan dari 5.349 ejaan yang seharusnya diproduksi. Bentuk kesalahan ejaan dibedakan menjadi enam aspek, yaitu kesalahan pada tataran penggunaan huruf kapital, penggunaan kata berimbuhan, penggunaan kata depan, penggunaan unsur serapan, penggunaan tanda baca titik, dan penggunaan tanda baca koma. Dari keenam aspek tersebut ditemukan 570 (48,76%) kesalahan penggunaan huruf kapital, 101 (6,33%) kesalahan penggunaan kata berimbuhan, 83 (31,20%) kesalahan penggunaan kata depan, 63 (6,16%) kesalahan penggunaan unsur serapan, 27 (3,57%) kesalahan penggunaan tanda baca titik, dan 101 (18,70%) kesalahan penggunaan tanda baca koma. Kedua, Dari persentasi kesalahan tersebut, kesalahan pada tataran penggunaan huruf kapital merupakan kesalahan yang paling dominan dilakukan oleh siswa, yaitu mencapai 570 (48,76%) kesalahan dari 1.169 huruf kapital yang seharusnya diproduksi. Selanjutnya, kesalahan yang paling sedikit terjadi adalah kesalahan penggunaan tanda baca titik yang mencapai 27 (3,57%) kesalahan dari 756 tanda baca titik yang seharusnya diproduksi

Nonlinear optics in Xe-filled hollow-core PCF in high pressure and supercritical regimes

Supercritical Xe at 293 K offers a Kerr nonlinearity that can exceed that of fused silica while being free of Raman scattering. It also has a much higher optical damage threshold and a transparency window that extends from the UV to the infrared. We report the observation of nonlinear phenomena, such as self-phase modulation, in hollow-core photonic crystal fiber filled with supercritical Xe. In the subcritical regime, intermodal four-wave-mixing resulted in the generation of UV light in the HE12 mode. The normal dispersion of the fiber at high pressures means that spectral broadening can clearly obtained without influence from soliton effects or material damage

Audit of postoperative nausea and vomiting in paediatric day case surgery

OBJECTIVE: To assess the incidence of PONV, delay in discharge or unplanned admissions in paediatric surgical cases done at the Surgical Day Care Unit at Aga Khan University between January and July 2009. METHODS: All paediatric ASA 1-2 cases, from 6 months to 18 years of age undergoing day case surgeries at the Surgical day care unit were included in this retrospective audit. Data was collected on a designed form filled with information from preoperative, intraoperative and postoperative recovery forms. Any relevant data was also noted from nurses notes in recovery room and step down unit. Episodes of vomiting, delay in discharge, or unplanned admission due to PONV were documented. Data was analyzed on SPSS 14. RESULTS: Out of 163 patients only one patient (0.6%) had an episode of vomiting in the recovery room and two patients (1.2 %) had vomiting in the step down unit. There was no delay in discharge or unplanned admission due to PONV in paediatric day cases during the period of our audit. CONCLUSION: The incidence of postoperative vomiting in paediatric day cases at our day care unit does not justify polymodal prophylaxis as a protocol for PONV

Identifikasi Sinyal Ecg Irama Myocardial Ischemia Dengan Pendekatan Fuzzy Logic

The heart is one of vital organs in human body. Incidence of heart disease can be fatal for the patient. Myocardial ischemia, the disease that is often suffered by the human, is a disease due to clogged heart arteries blood vessels. One of the ways to detect this disease is by reading the graph output of electrocardiogram (ECG) signal. ECG signal represents the condition and activity of the heart. Specialized knowledge, accuration and expertise are required to read ECG graph. To help expert or doctor, expert system based on artificial intelligent, such as Fuzzy Logic approach, can be applied to improve diagnostic accuracy and thoroughness. Fuzzy logic can be applied because of it flexibility to understand the linguistic variables used in identifying myocardial ischemia disease

Amalan pengurusan keselamatan bengkel kemahiran hidup (KHB) Sekolah Menengah Harian Daerah Batu Pahat

Kajian ini dijalankan untuk mengkaji sejauhmanakah persepsi pelajar terhadap amalan pengurusan keselamatan dari aspek keselamatan alatan dan bahan, diri dan rakan serta keselamatan am di bengkel Kemahiran Hidup sekolah menengah harian daerah Batu Pahat. Kajian berbentuk kuantitatif dilaksanakan di empat buah sekolah menengah harian daerah Batu Pahat iaitu SMK Datin Onn Jaafar, SMK Banang Jaya, SMK Dato Onn dan SMK Seri Gading. Sampel kajian terdiri daripada 350 orang pelajar tingkatan dua yang mengambil matapelajaran KHB dan data dikumpul menggunakan instrumen borang soal selidik. Dapatan kajian dianalisis menggunakan perisian Winsteps Version 3.69.1.11 dengan pendekatan Model Pengukuran Rasch sepenuhnya. Data dianalisis menggunakan teknik analisis diskriptif dan analisis inferensi iaitu ujian-t bagi menguji hipotesis kajian. Dapatan kajian menunjukkan bahawa amalan pengurusan keselamatan di bengkel diamalkan secara sederhana bagi ketiga-tiga aspek tersebut. Terdapat perbezaan yang signifikan di antara pelajar di bandar dan luar bandar iaitu t=-4.08 dan p=0.000 di mana nilai min ukuranya pula ialah -.19. Beberapa cadangan telah dikemukakan bagi penambahbaikkan seperti mengadakan kempen kesedaran dan menyediakan sudut standard operasi amalan pengurusan keselamatan agar pelajar sentiasa mematuhi peraturan semasa berada di bengkel Kemahiran Hidup
