Abstract

Tujuan penelitian ini untuk mengetahui penerapan sistem akuntansi pembelian bahan baku yang dilaksanakan oleh PT. Wono Jati Wijoyo dan mengetahui bagaimana hubungan sistem dan prosedur pembelian bahan baku terhadap pengendalian intern persediaan bahan bakunya. Objek kajian penelitian ini adalah sistem akuntansi pembelian bahan baku pada PT. Wono Jati Wijoyo Kediri. Pengumpulan data dilakukan dengan observasi, wawancara, serta dokumentasi. Teknis analisis data menggunakan deskriptif kualitatif. Hasil peneitian menunjukkan bahwa (1) Sistem akuntansi pembelian bahan baku pada PT. Wono Jati Wijoyo Kediri sudah cukup baik, dengan melibatkan berbagai fungsi dengan tugas dan tanggungjawab masing-masing. (2) Masih ada kelemahan terkait dengan adanya kegiatan yang masih dilakukan oleh satu fungsi, yaitu fungsi akuntansi yang merangkap kasir, dalam sistem ini melakukan pembayaran atas pembeian yang dilakukan. (3) pembelian bahan baku yang dilakukan satu kali dalam satu periode, dirasa kurang tepat, dapat saja perusahaan mengalami kekurangan bahan baku jika pesanan banyak, sehingga proses produksi terganggu.

Abstract

Pengenalan citra wajah atau Face Recognition adalah salah satu teknologi biometric yang telah banyak diaplikasikan dalam sistem keamanan. Perhitungan model pengenalan wajah memiliki beberapa masalah, kesulitan muncul ketika wajah dipresentasikan dalam suatu pola berisi informasi unik yang membedakan dengan wajah lain. Dalam implementasinya, secara umum pengenalan citra wajah dilakukan menggunakan sebuah webcam untuk menangkap citra wajah seseorang kemudian citra wajah tersebut dibandingkan dengan citra wajah sebelumnya yang telah disimpan. Pengujian ini dibagi menjadi dua bagian, yang pertama pengujian similarity kecocokan wajah dan yang kedua perhitungan False Acceptance Rate (FAR) dan False Rejection Rate (FRR). Pengujian menggunakan perangkat lunak Luxand FaceSDK dengan 30 sampel. Setiap sampel diambil 10 citra wajah untuk kemudian diuji kecocokan wajah, ekspresi dan kontur wajah dari sampel. Sistem ini mampu mengenali wajah dengan tingkat akurasi terbaik sebesar FAR = 8% dan FRR = 7% dengan nilai ambang 90%. Dan nilai ambang terburuk 10% dengan FAR = 95% dan FRR = 0,7%.

Abstract

Kebutuhan layanan telekomunikasi khususnya seluler meningkat dari tahun ke tahun. Perkembangan teknologi seluler sangat pesat di negara berkembang akibat keterbatasan dari ketersediaan jaringan kabel yang eksisting. Hal ini berdampak pada peningkatan kebutuhan energi.Pada makalah ini membahas beberapa penelitian sebelumnya serta parameter yang digunakan. Jaringan yang telah diuji coba pada penelitian sebelumnya menawarkan konsep sleep mode dan pengaturan daya transmisi pada base station. Dalam uji coba dengan cell deployment yang homogen didapat penurunan rasio green metric yang besar pada kondisi trafik rendah. Selain itu metode SPAM yang ditawarkan mampu mengurangi konsumsi energi hingga 17%. Penelitian lainnya menjelaskan bahwa dalam pengaplikasian sleep mode ada dua kemungkinan yang dilakukan dalam perencanaan cell deployment yaitu membangun cell-cell kecil lebih banyak sehingga mampu mempertahankan coverage.

Abstract

Real time tracking system technology has been made possible by integrating three technologies, namely global positioning system (GPS), database technologies such as geographic information system (GIS) and mobile telecommunications technologies such as general packet radio service (GPRS). This paper has proposed a vehicle tracking mechanism based on GPS tracker to build a real-time traffic information system. A GPS server is built to process data of position and speed of the vehicle for further processed into vehicle traffic information. The Server and GPS tracker is designed to communicate using GPRS services in real time. Furthermore, the server processes the data from the GPS tracker into traffic information such as traffic jam, dense, medium and smoothly. Test results showed that the GPS server is able to visualize the real position of the vehicle and is able to decide the category of traffic information in real time.

Abstract

The classification technique and data forecasting will probably be one of the techniques that will often be needed in handling or managing big data. So, from that the author analyzes the possible development of the existing algorithms. The purpose is to find possibilities in the use of reliable algorithms in a particular field, then can be adopted and implemented to develop forecasting techniques in the future. Based on these considerations, the authors conducted experiments by applying LVQNN to conduct shortterm forecasting on daily period of the Rupiah exchange rate. The literature that is used as a reference is the discovery of architectural data classification processes that resemble forecasting techniques. So, when there is a combination of Rupiah exchange histories, it is possible to find these combinations into certain classes based on predetermined parameters and historical data combination data and forecast values in the past. In this research the factors chosen as indicators that affect the Rupiah exchange rate are the amount of exports, the amount of imports, the inflation rate and also the world oil price. In this research the highest accuracy value in the testing process for the population reached 99.0991%. The increase in the percentage value of forecasting accuracy is influenced by the composition of the data. In this study the formation of data composition is influenced by distinct data. The selection of parameters which become distinct claused determines how the composition of the data will be formed. If the composition of the data is not correct, the test results will not be good. If the number of weights vector is smaller than the input data, the forecasting accuracy will decrease. Because the weight vector cannot represent data combinations that used during training or testing.

Abstract

Telecommunication technology and applications have developed fast recently. Hence this development will take energy consumption significantly. Many studies have been done on energy efficiency on cellular network. The studies are more focused on energy usage of the base station, as the base station is the component of cellular station which takes the most energy consumption. Therefore this study analyzes energy efficiency on homogeneous network of WCDMA/3G for outdoor environment. Energy consumption of three macro base stations is compared with energy consumption of 12 micro base stations. This comparison analysis has been conducted on the same Area Spectral Efficiency (ASE). The results show that the macro base stations are more efficient for energy usage than the micro base stations. However based on ASE requirements, the micro base stations are more efficient than the macro base stations on both busy hours and non-busy hour.
