Social Burden

Background- Electric burns and injuries are the result of electric current passing through the body. Temporary or permanent damage can occur to the skin, tissues, and major organs. Methods- This prospective study was carried out on patients admitted in burn unit of department of surgery M.G. Hospital associated with Dr. S.N. Medical College Jodhpur. Records of the patients admitted from January 2018 to December 2018 were studied. Bed head tickets of the patients evaluated in detail. Results- In our study out of 113 patients maximum no. of patients were in age group of 21-30 years 44 (38.94%) followed by age group <11 years in 21 (18.58%) patients and age group of > 60 years in only 3 (2.65%).39 (34.51%) patients were farmer and 15 (13.27%) were electrician in out of 113 total patients, while 37 (32.74%) were without any occupation. 65 (57.52%) cases of high voltage (HV) electrical injury and 48 (42.48%) cases were of low voltage (LV) electrical injury. Conclusion- Morbidity leading to permanent disabilities make the person physically dependent on others. It can be prevented by educating the people about the proper handling to electric circuits & devices. Proper communication among the electricians may help in lowering such accidents. Proper rehabilitation of the handicapped person & employment to the member of the affected family may reduce the social burden caused by such electricity concerned accidents.

Penelitian ini dilakukan untuk mengetahui peningkatan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia melalui penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) (POGIL) di kelas 11 SMAN 8 Pekanbaru. Penelitian ini menggunakan One Group Pretest-Posttest Design yang diadakan di SMAN 8 Pekanbaru pada tahun akademik 2017/2018. Objek penelitian adalah XI MIA 1 yang terdiri dari 32 siswa. Pengumpulan data siswa menggunakan teknik tes pretest dan posttest. Keberhasilan pembelajaran dalam meningkatkan kemampuan berpikir kritis siswa ditunjukkan oleh peningkatan kriteria berpikir kritis dari hasil pretest dan posttest yang menganalisis persentase skor berpikir kritis. Hasil penelitian menunjukkan bahwa ada peningkatan kemampuan berpikir kritis siswa. Siswa mengalami peningkatan dari kategori berpikir kritis sangat rendah ke kategori sangat tinggi dengan persentase 15,625%, dari kategori rendah ke kategori sangat tinggi adalah 40,625%, dari kategori rata-rata ke kategori sangat tinggi adalah 9,375%, dari kategori sangat rendah hingga kategori tinggi adalah 12,5%, dan dari kategori rendah ke kategori tinggi adalah 21,875%. Berdasarkan analisis data, dapat disimpulkan bahwa penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) mampu meningkatkan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia di SMAN 8 Pekanbaru.   The research was held to determine the improvement of student’s critical thinking ability on Thermochemistry subject through implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy at 11th Grade of SMAN 8 Pekanbaru. This research used One Group Pretest-Posttest Design which held in SMAN 8 Pekanbaru at academic year of 2017/2018. The object of research is XI MIA 1 that consist of 32 students. The data collection of students used test technique which are pretest and posttest. The success of learning in improvement of student’s critical thinking ability is showed by improvement of criteria of critical thinking from pretest and posttest results that analyzed the score percentage of critical thinking. The result of research showed that there was an improvement of student’s critical thinking ability. The students have an increase from the very low category of critical thinking to very high category with percentage of 15,625%, from low category to very high category is 40,625%, from average category to very high category is 9,375%, from very low category to high category is 12,5%, and from low category to high category is 21,875%. Based on data analyze, it can be concluded that implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy is able to improve student’s critical thinking ability on Thermochemistry subject at SMAN 8 Pekanbaru.

Abstrak. Desa Trusmi merupakan sentra batik sekaligus kuliner di Kabupaten Cirebon. Banyaknya pemegang usaha di bidang produksi batik mengakibatkan persaingan dagang diwilayah tersebut. Penelitian ini bertujuan untuk menganalisis SWOT (Strength, Weakness, Opportunities, Threats)  di salah satu usaha batik milik H. Edi Baredi atau sering dikenal dengan EB Batik Tradisional melalui inkuri terbimbing. Analisis meliputi profil usaha, aspek produksi, aspek tenaga kerja, aspek pemasaran dan aspek keuangan. Jenis penelitian ini menggunakan pendekatan kualitatif dengan metode deskripstif analisis. Berdasarkan analisis internal dan eksternal analisis SWOT, strategi yang  dilakukan oleh EB Batik Tradisional yaitu menghindari kehilangan penjualan dan profit yang disebabkan banyaknya persaingan dagang di kawasan sentra batik Trusmi dengan munculnya inovasi baru. Penguatan karakter pada produksi batiknya dapat mengatasi pesaingan dagang dan menambah daya tarik pembeli. Kata Kunci: SWOT, Inkuiri Terbimbing, dan Kegiatan Ekonomi Abstract. Trusmi village is a center of batik as well as culinary in Cirebon Regency. A large number of business holders in the field of batik production has resulted in trade competition in the region. This study aims to analyze SWOT (Strength, Weakness, Opportunities, Threats) in one of the batik business owned by H. Edi Baredi or often known as EB Traditional Batik through guided injury. The analysis includes the business profile, production aspects, labor aspects, marketing aspects, and financial aspects. This type of research uses a qualitative approach with descriptive analysis method. Based on internal and external analysis of the SWOT analysis, the strategy carried out by EB Traditional Batik is to avoid losing sales and profits due to the high level of trade competition in the Trusmi batik center area with the emergence of innovations. Strengthening the character of batik production can overcome trade competition and increase the attractiveness of buyers. Keywords: SWOT, Guided Inquiry, and Economic Activities

The study examines the electrochemical properties of a coating based on water sodium silicate and pure zinc dust (ZSC, working title - TTL-VN) using the Electrochemical Impedance Spectra (EIS) with AutoLAB PGSTAT204N. The system consists of three electrodes: Ag/AgCl (SCE) reference electrode in 3 M solution of KCl, auxiliary electrode Pt (8x8 mm) and working electrodes (carbon steel with surface treatment up to Sa 2.5) for determination of corrosion potential (Ecorr) and calculation of equivalent electric circuits used for explanation of impedance measurement results. It was shown that electrochemical method is effective for study of corrosion characteristics of ZSC on steel. We proposed an interpretation of the deterioration over time of the ability of zinc particles in paint to provide cathodic protection for carbon steel. The results show that the value of Ecorr is between -0,9 and -1,1 V / SCE for ten days of diving. This means that there is an electrical contact between the zinc particles, which provides good cathodic protection for the steel substrate and most of the zinc particles were involved in the osmosis process. The good characteristics of the TTL-VN coating during immersion in a 3,5% NaCl solution can also be explained by the preservation of corrosive zinc products in the coating, which allows the creation of random barrier properties.
