Pembangunan Sistem Informasi Layanan Pelanggan Di Pdam Tirtamarta Berbasis SMS

Perusahaan Daerah Air Minum (PDAM) Tirtamarta Yogyakarta merupakan Perusahaan air minum yang memiliki lebih 35.000 pelanggan. Dengan banyaknya pelanggan tersebut, PDAM dituntut untuk terus meningkatkan pelayanan kepada pelanggan. Salah satunya layanan informasi tentang informasi tagihan serta permohonan reparasi dari pelanggan. Selama ini masalah yang dihadapi adalah pelanggan harus menunggu datangnya surat tentang tagihan yang harus dibayar dan kalau ada kerusakan untuk mengajukan reparasi harus datang untuk mengisi formulir terlebih dahulu.. Untuk itu dalam penelitian ini telah dibangun Sistem Informasi Layanan Pelanggan di PDAM Berbasis SMS. Metode penelitian yang dilakukan melalui pendekatan waterfall yaitu menganalisis kebutuhan pengguna, mencermati model bisnis yang ada, pengembangan algoritma tagihan rekening air,pembuatan basis data, koding dengan Visual Basic 6.0, Protocol Data Unit (PDU) sebagai bahasa SMS, serta AT Command sebagai perintah untuk komunikasi ponsel dengan PC. Setelah program jadi, dilakukan uji program dengan metode black box test dan alpha test. Penelitian yang dibuat menghasilkan sebuah sistem Layanan Informasi Pelanggan yang membantu memudahkan dan mempercepat layanan permohonan reparasi dan informasi tagihan pelanggan yang akan jatuh tempo

The Effort to Increase the Quality of the Learning Process of Accounting through the Implementation of the Cooperative Learning Model of Numbered Heads Together (NHT) Type of the 11th-grade Students of SMA Negeri 3 Sragen Majoring in Social Science in the Academic Year of 2012/2013. Principal Advisor: Prof. Dr. Trisno Martono, M.M. Co-advisor: Dr. Susilaningsih, M. Bus. Thesis: The Graduate Program in Economics Education, Sebelas Maret University. Surakarta. 2013. The objectives of this research are to investigate: (1) the implementation of the learning model of Numbered Heads Together (NHT) type in increasing the quality of the learning process of Accounting of the 11th-grade students of Class Social Science 4 of SMA Negeri 3 Sragen in the academic year of 2012/2013; and (2) the implementation of the learning model of Numbered Heads Together (NHT) type in increasing the quality of the learning result of Accounting of the 11th-grade students of Class Social Science 4 of SMA Negeri 3 Sragen in the academic year of 2012/2013. This research used classroom action research approach. The samples of this research consisted of the 11th-grade students of Class Social Science 4 of SMA Negeri 3 Sragen as many as 32 students. The data of this research were gathered through observation, interview, test, and documentation. The procedure of this research consisted of the stages of: (1) identifying problems, (2) preparing actions, (3) setting up action plan, (4) implementation of actions, (5) observation, and (6) setting up report. The process of this research was conducted in two cycles. Each cycle consisted of four stages, namely: (1) planning of action, (2) implementation of action, (3) observation and interpretation, and (4) analysis and reflection. Each cycle was conducted in three meetings as long as 6 x 45 minutes. Based on the results of the research, a conclusion is drawn that the implementation of the learning model of Numbered Heads Together (NHT) type can increase the quality of the learning process and the learning result of Accounting. This is seen from the increasing learning activeness of the students in the apperception, in taking part of the learning process, in discussing the question exercise in class punctually and correctly as well as the learning result completeness. As a result, the students can comprehend the learning material of Accounting more easily in such a way that the quality of the learning process and the learning result of the students increases. The learning process through the learning model of Numbered Heads Together (NHT) type can increase the learning quality through the steps which have been established previously in the Lesson Plan. Thus, the implementation of the learning model of Numbered Heads Together (NHT) type increases the quality of the learning process and the learning result of the students

Sistem Informasi Geografi (SIG) Pencarian ATM Bank Kaltim Terdekat Dengan Geolocation Dan Haversine Formula Berbasis Web

Memberikan layanan yang terbaik bagi para nasabah merupakan prioritas utama setiap bank, termasuk di antaranya adalah Bank Kaltim di Kalimantan Timur, khususnya yang berada di Kota Samarinda. Salah satu layanannya adalah dengan menempatkan mesin ATM di setiap sisi kota yang nantinya dapat memudahkan nasabah dalam melakukan transaksi keuangan. Mesin ATM Bank Kaltim tersebar di banyak tempat, akan tetapi informasi mengenai lokasi ATM di Kota Samarinda masih terbatas dan terkadang membuat nasabah mengalami kesulitan dalam menemukan mesin ATM Bank Kaltim. Penentuan lokasi dengan Sistem Informasi Geografi (SIG) dapat menggambarkan informasi jarak dan tujuan sesuai dengan keinginan pengguna. SIG akan sangat tepat digunakan sebagai sarana untuk mengolah informasi lokasi ATM Bank Kaltim di Kota Samarinda. Salah satu metodenya yaitu Haversine Formula, yang merupakan metode yang diterapkan di dalam aplikasi SIG dalam menentukan lokasi ATM yang terdekat dengan user. Haversine Formula adalah persamaan yang digunakan dalam navigasi, yang memberikan jarak lingkaran besar antara dua titik pada permukaan bola (Bumi) berdasarkan garis bujur dan lintang. SIG yang dibuat dapat memberikan informasi mengenai lokasi ATM terdekat dan petunjuk arahnya. Hasil dari penelitian ini, Haversine Formula untuk proses perhitungan menentukan lokasi ATM terdekat dapat diterapkan dan memberikan informasi ATM untuk pengguna atau nasabah Bank Kalti

Perilaku Minum Sopi pada Remaja di Kecamatan Maulafa, Kota Kupang

Sopi drinking behavior among adolescents in KupangPurposeThis research aimed to identify sopi drinking behavior among adolescents in Maulfa.MethodsThis research was a qualitative study with an exploratory design and phenomenological approach. The main informants were adolescents who drink sopi and supporter informants were religious leaders or community leaders, parents, sopi sellers, health workers and adolescents who did not drink sopi. Data collection used observations, In-depth interviews, and focus group discussions. The informant sampling was obtained by purposive sampling through convenience sampling strategy.ResultResults showed that adolescents start to drink sopi since junior high school and senior high school. They have known sopi since the age of 13-17 years old. The number of sopi consumed is usually about two-six bottles and they drink it together with their friends. Some factors that encourage teenagers to consume sopi are: 1) to obtain many friends and build friendship; and 2) to know each other well and to make a good communication between them.ConclusionSocial factors such as a culture play an important role to build the sopi drinking behavior in adolescents. The adolescents consider that sopi drinking behavior is an easy thing to do because it is easy to obtain and cheap

Structural analysis and corrosion studies on an ISO 5832-9 biomedical alloy with TiO2 sol–gel layers

The aim of this study was to demonstrate the relationship between the structural and corrosion properties of an ISO 5832-9 biomedical alloy modified with titanium dioxide (TiO2) layers. These layers were obtained via the sol–gel method by acid-catalyzed hydrolysis of titanium isopropoxide in isopropanol solution. To obtain TiO2 layers with different structural properties, the coated samples were annealed at temperatures of 200, 300, 400, 450, 500, 600 and 800 C for 2 h. For all the prepared samples, accelerated corrosion measurements were performed in Tyrode’s physiological solution using electrochemical methods. The most important corrosion parameters were determined: corrosion potential, polarization resistance, corrosion rate, breakdown and repassivation potentials. Corrosion damage was analyzed using scanning electron microscopy. Structural analysis was carried out for selected TiO2 coatings annealed at 200, 400, 600 and 800 C. In addition, the morphology, chemical composition, crystallinity, thickness and density of the deposited TiO2 layers were determined using suitable electron and X-ray measurement methods. It was shown that the structure and character of interactions between substrate and deposited TiO2 layers depended on annealing temperature. All the obtained TiO2 coatings exhibit anticorrosion properties, but these properties are related to the crystalline structure and character of substrate–layer interaction. From the point of view of corrosion, the best TiO2 sol–gel coatings for stainless steel intended for biomedical applications seem to be those obtained at 400 C.This study was supported by Grant No. N N507 501339 of the National Science Centre.
