EFEK REPETITIVE TRANSCRANIAL MAGNETIC STIMULATION TERHADAP PENINGKATAN KEMANDIRIAN DAN PERBAIKAN DEPRESI PASCA STROKE ISKEMIK
Full text linkLatar Belakang: Stroke bisa terjadi karena kelainan pada pembuluh darah serebral. Sisa gejala yang disebabkan oleh stroke seperti menurunnya kemandirian dan depresi. Bila hal ini dibiarkan dan tidak mendapatkan perawatan atau terapi yang tepat maka akan mempelambat proses pemulihan. Salah satu terapi stroke yang diyakini mampu meningkatkan kemandirian dan memperbaiki depresi adalah Repetitive Transcranial Magnetic Stimulation, Repetitive Transcranial Magnetic Stimulation (rTMS) merupakan terapi complementer dengan stimulus gelombang elektromagnetik. Metode: Penelitian Cross Sectional dengan menggunakan desain kelompok kontrol Nonequivalent, dimana ada 2 kelompok kelompok kontrol dan kelompok intervensi, masing - masing kelompok diukur 2 kali yaitu pra dan pasca selama 2 minggu. Jumlah sampel untuk masing-masing kelompok terdiri dari 15 orang. Hasil: ada perbedaan peningkatan kemandirian antara kelompok intervensi dan kontrol p(0.001) dengan nilai BI (Barthel Index) untuk kelompok intervensi ketergantungan ringan 10 (66.7%), sedangkan pada kelompok kontrol ketergantungan ringan 1(6.7%), begitu pula pada perbaikan depresi antara kedua kelompok terdapat perbedaan dengan p(0.001) dengan nilai HDRS (Hamilton Depression Rating Scale) untuk kelompok intervensi depresi ringan 7 (46.7%), sedangkan kelompok kontrol depresi ringan 1(6.7%)
MULTI-OBJECTIVE OPTIMIZATION OF POWER GENERATION EXPANSION IN WEST AND SOUTH SULAWESI POWER SYSTEM
Full text linkIn 2013, most of electricity demand of South and West Sulawesi Power System was fulfilled by fossil fuel power plants. The use of fossil fuel not only leads to high operational cost, but also emits high amount of carbon. To control carbon emission Kyoto Protocol and Peraturan Presiden emphasize that the generation expansion has to consider the environmental aspect and economic aspect. In order to obtain an efficient plan with low carbon emission, this research conduct multi-objective optimization of power generation expansion in South and West Sulawesi power system. The optimization was conducted by combining Particle Swarm Optimization (PSO) method and Analytic Hierarchy Process (AHP). The optimization in this research was consisted of cost and carbon emission function. Cost function itself was divided into three items. The items are capital cost of power plant, operation and maintenance cost, and investment cost of transmission line. To obtain the investment of transmission line, transmission expansion plant considering power losses (TEP) was performed first. The aim of TEP is to determine which transmission line should be added into the power system. The result of simulation and priority analysis shows that A6 is an efficient power plant expansion planning that fulfill environmental and economic aspect. Planning A6 is consisted of PLTA (996 MW), PLTMG (71 MW), PLTU (34 MW) and PLTGU (737 MW). Investment cost of transmission line, operational cost of power plant and investment cost of new power plant are Rp351.000.000.000, Rp4.000.000.000, and Rp.60.596.000.000.000 respectively. The accumulation of carbon emission for 5 periods by applying plan A6 is 651 tons
THE SYSTEM OF MONITORING LEVELS OF GASES SUCH AS CARBON MONOXIDE (CO) IS IN THE AIR
Full text linkThis research aims to monitor carbon monoxide gas, thus obtained data about the presence of carbon monoxide gas in the air as well as the location of the place of monitoring and displayed in a web form with the addition of maps in real time. This system consists of DT-Sense Carbon Monoxide Sensor used to detect carbon monoxide gas, GPS/GSM/GPRS and a microcontroller as the pemproses sensor data and data from GPS position which is then sent to the web server via the Internet. This website is displayed in the form of a point on a digital map that contains carbon monoxide gas information, date and time of the measurement.
