Abstract

Maternal death is the worst performing of the Millennium Development Goals (MDGs) and Indonesia did not achieve its MDG #5 target in 2015. Therefore, the Indonesian government needs to review its strategies to decrease maternal deaths. One cause of maternal death is a lack of infrastructure, which can delay reaching emergency obstetric care (called Poned). This qualitative study investigated problems with priority planning in the Kupang district in order to improve access to emergency obstetric care (EMOC). A number of observations were conducted in the musrenbang (the district planning process). Interviews were carried out to gain an insight into the planning process from village to district level. A model for travel time to EMOC was created to support this study. In this study, six problems were identified in the district planning (musrenbang) regarding improving access to EMOCs. Those were (1) no planning proposal about improving access to EMOC, (2) budget constraints, (3) decision on the priority planning not being based on the level of urgency, (4) undue political influence, (5) lack of evidence and (6) incorrect measure of accessibility to obstetric care. Hence, to improve access to EMOC, scenario modelling with combined cost-benefit analyses (CBA) as an evidence-based planning should be applied in the musrenbang. It will help the health planners in Eastern Indonesia to gain a deep understanding about the problems in district planning process for access improvement to EMOC. Scenario modelling with CBA could provide the evidence during musrenbang.

Abstract

The general objective of this work was investigation of radioisotope distribution and accumulation center in mineral deposit at sub-district of Middle Kupang West Timor Island Indonesia. The purposes of research were: to map of radioisotope distribution in the mineral deposit, to estimate area of radioisotope accumulation center in the mineral deposit, to establish range of nuclear radiation counts in the center region of radioisotope content in mineral deposit. The general methods used in this research were observation, survey, mapping, analysis, and interpretation. Procedures detail of research consists of: observe and identify the potential region and plot gridding, calibrate equipment necessary, measure background count in around of survey location and nuclear radiation in the survey location, plot of three dimensions curve and contour after corrected by background count. Based on geology information or geology data (drilling data) three depth levels determined (about 20 m, 40 m and 60 m), Radiation powers were calculated for estimation of accumulation center of radioisotope in deposit mineral, and contour and three dimensions curves of radiation power of radioisotope in deposit mineral were plotted. Results: Based on three dimensional curves and contour map (radiation counts and radiation powers on three levels) of radioisotope in mineral deposit respectively was distributed on area 3.00 x 106 m2, and 1.56 x 104 m2. The interval of radiation counts of radioisotope in mineral deposit was 10 counts per minute-137 counts per minute. Keywords: Radiation, measurement, radioisotope, mineral, deposit

Abstract

Dalam penelitian ini, kami mendemonstrasikan proses fabrikasi, sintesis dan analisis spektrum serapan material karbon nanodots (K-dots) dari buah sirsak asal Kabupaten Kupag, Propinsi Nusa Tenggara Timur. Proses fabrikasi material K-dots ini menggunakan metode microwave. Jus sirsak (0,5 gram, 5 mL aquades) dipanskan dengan microwave selama satu jam pada daya 900 watt. Warna sampel setelah pemanasan pada kondisi ini adalah hitam kecoklatan yang mengindikasikan telah terbentuknya material K-dots. Selanjutnya 60 mL aquades ditambahkan ke dalam sampel ini dan disonikasi selama 30 menit dan disentrifugasi pada 1500 rpm selama 20 menit. Sampel ini disaring dan dimurnikan dengan aquades. Dengan iradiasi lampu UV 365 nm, material K-dots ini memancarkan warna biru keabuan yang menunjukkan bahwa material K-dots berfluoresens biru keabuan. Berdasarkan spektrum serapannya, jangkauan spektrum serapan material K-dots ini adalah 200 – 450 nm dengan puncak serapan terjadi pada 241-300 nm yang merupakan karakteristik material K-dots. Setelah disintesis dengan logam besi, jangkauan spektrum serapannya adalah 200 sampai 450 nm tetapi intensitas serapannya menurun yang menunjukkan adanya ikatan antara material K-dots dengan ion logam besi. Hasil ini mengindikasikan bahwa material K-dots ini berpotensi untuk diaplikasikan sebagai material sensing ion logam besi. Dengan demikian, hasil-hasil penelitian ini dapat membuka peluang yang besar tentang pemanfaatan material K-dots sebagai sensor logam Fe dan ion-ion logam lainnya.

Abstract

Penyandang tunanetra di Kupang biasanya menggunakan tongkat sebagai alat bantu berjalan. Namun tongkat yang digunakan oleh tunanetra belum dapat mendeteksi adanya genangan air. Oleh karena itu, pada penelitian ini, dikembangkan alat bantu pada tongkat tunanetra untuk mendeteksi objek berupa genangan air yang dapat menghalangi tunanetra saat berjalan. Alat bantu ini dilengkapi sensor ultrasonik HC-SR04 sebagai pendeteksi objek dan water level sebagai pendeteksi genangan air. Output dari sensor ultrasonik dan water level akan dikonversi oleh Arduino Nano menjadi suara melalui bunyi Buzzer. Hasil penelitian ini menunjukan bahwa sensor ultrasonik pada tongkat mampu mendeteksi keberadaan objek dengan jarak 2 cm-100 cm dan water level mendeteksi genangan air dari 0 cm-4 cm. Namun jika jarak objek dan genangan air cm maka sensor tidak dapat mendeteksi keberadaan objek dan genangan air tersebut. Dengan demikian dapat disimpulkan bahwa tongkat tunanetra telah bekerja dengan baik untuk mendeteksi obyek dan genangan air. Tongkat ini mampu memberikan peringatan kepada Tunanetra ketika menemukan obyek dan genangan air yang berada pada jarak 2 hingga 100 cm di depan pengguna.

Abstract

The geographical conditions of an area influence accessibility problems. The difficult geographical conditions caused travel time to the location of the obstetric emergency center to be very long. One of the causes of the high maternal mortality rate in Eastern Indonesia is the long time to travel to Basic Emergency Obstetrics Cares. This study aims to model the travel time to the PONED-Pelayanan Obstetri Neonatal Emergensi Dasar (Basic Emergency Obstetric and Neonatal Care-BEmONC) in a mountain region. The difficulties in access to obstetric care could cause maternal mortality in mountain regions. This study was done on the island of Adonara in the Flores Timur district. Adonara Island has a high maternal mortality rate. Modeling accessibility used a raster-based model to model travel time. The data used Landsat 8 imagery, Digital Elevation Model (DEM), and road network data to obtain a land cover layer. The Saga GIS travel time calculation tool is used to calculate the accumulated cost of travel time. The cost is based on the speed of travel through each land cover pixel to the location of the Puskesmas Waiwerang (PONED 1) and Puskesmas Waiwadan (PONED 2). The results of the travel time modeling show that people living in five sub-districts reach the two PONED locations in ≥ 1 hour. The longest time for people to travel to PONED is ≥ 6 hours from Ile Boleng sub-district because there is a mountain in the Ile Boleng sub-district. The scenario of adding one PONED shows that only people living in two sub-districts reach the PONED ≥ 1 hour. This spatial modeling of travel time to the location of the PONED (emergency obstetric care) can be used by local governments in eastern Indonesia to improve access to the location of basic obstetric emergency health centers in mountain areas.
