DIGITASI TOWER BTS KOTA BANDA ACEH DAN INFRASTRUKTUR SEKITARNYA DENGAN MENGGUNAKAN DATA SATELIT BERESOLUSI TINGGI

ABSTRAK BTS (Base Transceiver Station) berfungsi sebagai jembatan perangkat komunikasi pengguna dengan jaringan menuju jaringan lain. Satu cakupan pancaran BTS dapat disebut cell. Sistem Informasi Geografis merupakan suatu sistem yang digunakan sebagai media penampil keadaan topografi suatu wilayah. Sistem Informasi Geografis tidak lepas dari data spasial, yang merupakan sebuah data yang mengacu pada posisi obyek dan hubungan diantaranya dalam ruang bumi. Data spasial merupakan salah satu item dari informasi dimana didalamnya terdapat informasi mengenai bumi termasuk permukaan bumi, dibawah permukaan bumi, perairan, kelautan dan bawah atmosfer. Pada proyek akhir ini akan dirancang sistem informasi geografis pemetaan tower BTS dan infrastruktur sekitar BTS dengan menggunakan software Quantum GIS. Quantum GIS merupakan aplikasi open source, disini Quantum GIS digunakan untuk mendigitasi peta yaitu lokasi tower BTS dan infrastruktur sekitar tower. Informasi yang disajikan meliputi nama, alamat, dan wilayah. Hasil yang diharapkan dalam pembuatan proyek akhir ini yaitu dengan dibuatnya sistem informasi geografis mengenai lokasi tower BTS ini memudahkan untuk mengetahui dimana posisi BTS, dan juga memudahkan dalam memperbarui peta lokasi tower BTS. Kata kunci : BTS, Sistem Informasi geografis, Quantum Gis, Data Spasia

Serum 25-hydroxyvitamin-D level and atopic dermatitis severity in children

Background Vitamin D plays an important role in the immune system. It inhibits B-lymphocyte proliferation and modulates the humoral response to suppress IgE production. Studies on the relationship between serum 25-hydroxyvitamin-D level and the severity of atopic dermatitis in several countries have had varying results. Objective To assess for a possible correlation between serum 25-hydroxyvitamin-D level and atopic dermatitis severity in children. Methods A cross-sectional study was conducted in 26 children with atopic dermatitis from September to December 2015. We evaluated the severity of disease using the Scoring of Atopic Dermatitis (SCORAD) index and measured serum 25-hydroxyvitamin-D levels. Spearman’s test was used to analyze for a correlation between serum 25-hydroxyvitamin-D level and the atopic dermatitis  score in children with atopic dermatitis. Results Mean SCORAD index was 32.0 (SD 14.99) , with a range of 10.9 to 71.4. Mean serum 25-hydroxyvitamin-D level was 41.1 (SD 24.81) ng/mL, with a range of 10-137 ng/mL. There was a moderate correlation between serum 25-hydroxyvitamin-D level and the SCORAD index (r=-0.591), with higher SCORAD index associated with lower serum 25-hydroxyvitamin-D level (P=0.01). Conclusion There is a moderate correlation between serum 25-hydroxyvitamin-D level and the SCORAD index in children with atopic dermatitis

Success Factors of Village-Owned Enterprises (BUMDes) Performance in Indonesia: An Exploratory Study

The full autonomy given to village governments by the Indonesian government coming with the demand to establish Village-Owned Enterprises (BUMDes) brings both opportunities and challenges. The reason is that not all BUMDes which have been established could perform satisfactorily. In fact, out of 3900 existing BUMDes, only a small percentage showed satisfactory performance. Based on this background, this research aims to investigate key success factors which drive the performance of BUMDes. The research was conducted from November to December 2018. The research subjects were BUMDes Amarta, Srimartani Makmur, and Tirtonirmolo, which are located in the Special Region of Yogyakarta, Indonesia. These three BUMDes were chosen because they serve as a benchmark for how BUMDes in Indonesia should be managed. The research informants were directors and employees of these BUMDes where each BUMDes was represented by one director and one employee. The data were obtained from direct interviews and documentation. The data were analyzed using a qualitative approach, consisting of such steps as data reduction, data display and conclusion drawing. The results indicated that the factors that drive the performance of BUMDes were BUMDes employees’ patriotism and passion, skills, training, level of education, experience, honesty (ethical behavior), having a sense of responsibility, sincerity, seriousness, caring for the environment and society, being resilient, cohesiveness of teamwork, transparent communication between BUMDes managers, never-give-up attitude in trying to achieve the performance targets, religiosity, work satisfaction, visionary (transformational) leadership style, and the presence of incentive mechanisms

The Effects of Calcium Supplementation on Blood Lead Levels and Short-term Memory of Chronically Exposed Children: A Clinical Trial Study

AIM: The purpose of this study is to determine the effects of calcium supplementation to decrease blood lead levels (BLLs) of children at high risk for chronic lead poisoning and to determine its effects on short-term memory. MATERIALS AND METHODS: Children aged 8–12 years lived in the highest traffic density in Medan randomly included in this quasi-experimental study, divided into two groups (control and supplementation group received tablet contain four hundred milligrams oral calcium twice daily for 3 months). Samples for BLLs were collected before and after 3 months of supplementation, and short-term memory measurements are carried out by picture and forward digital span test. Descriptive statistics were calculated at baseline and 3 months; comparison between before and after treatment was assessed with t-tests, p < 0.05 considered statistically significant. RESULTS: BLLs samples, who are exposed to lead for >6 months were ranging between 0.4–12 μg/dL. Median BLLs in supplementation group before treatment was 2.1 μg/dL and after treatment was 0.01 μg/dL (p < 0.01); difference between median in BLLs after treatment in supplementation group was 2.090 μg/dL (p = 0.004). Score memory picture in the supplementation group before treatment was 61.4 ± 24.83 and after treatment was 76.21 ± 15.97 (p<0.01). Score memory digital span in the supplementation group before treatment was 5 (3–7) and after treatment was 7 (5–7) (p < 0.01). CONCLUSION: Three months of oral calcium supplementation 400 mg twice daily for high-risk chronic lead poisoning children reduced BLLs significantly and improved their short-term memory

Peran Vasodilator pada Gagal Jantung Anak

Vasodilator dapat menurunkan tahanan vaskular sistemik dengan memperlebar pembuluh darah arteriol (mengurangi afterload) dan/atau menurunkan preload (tekanan pengisian ventrikel kiri dengan venodilatasi) terbukti berperan dalam penanganan gagal jantung kongestif. Pada pasien gagal jantung berat, jika pengobatan konvensional tidak adekuat maka penggunaan vasodilator sangat bermanfaat. Pada anak, pemberian vasodilator diindikasikan pada keadaan tidak responsif terhadap pengobatan konvensional, pada persiapan operasi, keadaan menunggu saat operasi jantung, pasca operasi jantung dan jika diperlukan penurunan preload dan/atau after load. Pada makalah ini dibahas beberapa jenis vasodilator yang sering dipakai pada gagal jantung ana

Association between sleep quality and obesity in adolescents

Background Sleep quality can be measured by the Pittsburgh Sleep Quality Index (PSQI). One component of the PSQI is duration of sleep, which is often highly inadequate in adolescents. Inadequate sleep may lead to obesity in adolescents. Objective To assess for an association between sleep quality and incidence of obesity in adolescents. Methods This case–control study was conducted at Santo Thomas I Senior High School, Medan, North Sumatera,  from July to August 2015. A total of 227 adolescents were divided into two groups: the case group consisting of 101 obese adolescents and the control group consisting of 126 non-obese adolescents. Study data was collected by questionnaires and PSQI. We interviewed subjects on their food consumption for the three days prior and calculated their average caloric intake. The data were analyzed by non-paired T-test, Chi-square, Mann-Whitney, and multivariate analyses. Results There was a significant association between sleep quality and obesity [OR 3.87 (95%CI 1.920 to 7.829)]. Median PSQI (range) score in the obese group was significantly higher than in the non-obese group [6.00 (2-16) vs. 5.00 (2-12), respectively (P=0.0001)]. In addition, sleep latency (P=0.002) and sleep duration (P=0.0001) were significantly different between groups. Multivariate analysis revealed a significant association between poor sleep quality and high caloric intake. Conclusion Sleep duration in obese adolescents is significantly shorter than that in non-obese adolescents. In addition, sleep latency in obese adolescents was significantly longer than that in non-obese adolescents
