Abstract

Manusia tidak memiliki kemampuan untuk mengetahui apa yang akan terjadi di masa depan, seperti misalnya mengetahui barang yang laku dijual. Tetapi manusia dapat memprediksi sesuatu dengan melakukan analisa, misalnya memprediksi produk yang paling dicari atau dimiati di bulan depan atau tahun depan. Untuk dapat memprediksi hal tersebut dibutuhkan suatu ekosistem yang dapat membantu. Data warehouse dapat menjawab permasalahan tersebut. Data warehouse adalah sistem yang mengekstrasi, membersihkan, menyesuaikan, dan mengirim sumber data ke dalam penyimpanan data dimensi dan kemudian mendukung dan mengimplementasikan query dan analisis untuk tujuan pengambilan keputusan. Dengan data warehouse data historis suatu toko dapat dianalisa dan diketahui penjualan barang apa saja yang paling diminati oleh konsumen. Dengan mengetahui hal tersebut, pedagang dapat memprediksi barang apa saja yang dijual dan berapa jumlah barang yang harus di stok di tokonya sehingga dapat mengurangi tumpukan barang di gudang.

Abstract

The number of fake lubricants in Indonesia has made many people nervous. In 2008, 50% to 60% of lubricants that already existed in Indonesia were fake, therefore carefulness was needed in choosing these lubricating products. The first step that can be done to identify fake lubricants is to recognize by its color. Therefore, this research aims to design a device that is able to recognize the color of lubricants using a webcam. The research sample is base oil with levels of red and blue, each of which is 0 ppm, 10 ppm, 50 ppm, 100 ppm, 150 ppm, and 200 ppm. This sample is characterized by the color composition used as a reference system, then tested to identify other samples. Characterization is done by placing a sample on a cuvette and inserting it into the sample room with adequate lighting. The web camera is used to take sample pictures, then the image is analyzed based on color composition. Based on the results of tests that have been conducted, it shows that this system is able to identify 100% lubricant samples correctly. These results indicate that it is very possible to develop an early detection method for lubricating oil based on the composition of the colors using a webcam.

Abstract

The problem of data loss in a dataset is experienced in surveys for data collection which are usually caused by no response from units or items during the survey data collection process. The loss of a data can significantly influence the results of a study. The inaccuracy in choosing a solution to overcome these problems can result in a less than optimal outcome that tends to be biased. Some methods that are widely used to solve these problems are using the K Nearest Neighbor (K-NN) and Naïve Bayes methods, the main purpose of this study is to compare the performance of the two methods. From the results of the K-NN, the results were better, where the Mean Square Error (MSE) is bigger than 1 and MAPE around 10-16%, while Naïve Bayes got MSE values bigger than 1 and MAPE ​​around 26%.

Abstract

The neonatal period is an important period in life. Infant Mortality Rate (IMR) is the number of infant deaths in the first 28 days of life (neonatal) per 1000 live births (PERMENKES No 53, 2014). IMR in Indonesia is still high compared to other ASEAN countries, data in 2016 shows that IMR reaches 25.5, it’s meaning that there are around 25.5 deaths per 1,000 babies born (BPS, 2016). Poor neonatal management clinically will cause abnormalities, and can even lead to lifelong disability, and death, while administratively can cause legal problems. Neonatal management requires complete clinical data support, relevance, accurate and timeliness aspects. This research is a mixed method research with action research approach and prototype method in the development of Clinical Decision Support System (CDSS). This study produced CDSS based on Integrated Childhood Illness Management (IMCI) algorithm for neonatal service management in primary health care center. The results of testing system using black-box technique is accordance with the requirements and obtained a valid overall result. DSS IMCI can be integrated with Electronic Health Record (EHR) so can occur for appropriate clinical decision making.

Abstract

Conventional information systems that are installed and used in public service places such as city parks require expensive and complex systems. To streamline cost and installation time, system complexity can be simplified using a relatively inexpensive system while still providing sufficient service to the community. In this study the display boards of information prepared for zoo services managed by the city government, designed and built using a mini personal computer that is now widely available on the market. To perform its function as an information display board, some eye-catching animated videos are played back and forth as needed. From the results of the implementation and testing in actual conditions it is concluded that the information display system at the zoo using personal mini computer is more interesting for visitors with a delay time of 10.82 seconds for 8 hours of playback. This indicates that this system can work reliably enough to provide information according to the visitor's needs without interruption of time delay between video information.
