Rancang Bangun Sistem Pengendali Irigasi Berbasis Analisis Evapotranspirasi Dengan Kontroler On/off

Food is a basic requirement for life so that the availability is absolutely necessary of all time. The need for food continues to increase along with the growth of population. While the source of the water decreases and becomes scarce during the dry season. So the real action to improve agricultural products is indispensable. One way to meet the water needs of plants properly is to calculate the crop evapotranspiration with Penman-Monteith equation. While the tools to realize the results of these calculations is to create an irrigation controllers system. Irrigation control system that is made has inputs from weather environment obtained with the sensor and has an output valve to drain the water. The main parameters are used as input air temperature, wind speed, relative humidity, and solar radiation. All parameters acquired digitally except solar radiation, solar radiation are acquired from correlation shaping using artificial neural networks algorithm with input temperature and light intensity. The type of valve used is on/off with controller type used is on/off. This study divided into three steps, the first steps is modeling with matlab software. Second, the design of simulation tools with results shown on oscilloscope. Third, the design of the controller device. Artificial neural networks are used feedforward structure with 2 hidden layer. The amount of the first layer size is 15x2 matrix and The amount of the second layer is 1, which produces a fairly good prediction, i.e., with the largest error of 1.13%. The simulation results of the control system on/off produces an error of 1.8% while the application of control system on/off produces an error of 2.20%

Modelling Modal Shift Preference of Freight Transport on Surabaya-Jakarta Corridor : A Preliminary Survey

The market share of freight transport which is dominated by road transport and accompanied by unbalanced of infrastructure’s growth and freight demand has created various negative impacts on existing transportation system. The shift of freight transport from road to rail and sea is expected to reduce those impacts. Research on the behavior of freight mode choice and the extent to which the user is willing to trade off the attribute change needs to be done so that the amount of modal shift will be known. The main objective of the study was to produce a model of mode choice based on preference surveys among forwarders, as well as to provide inputs for policy improvement and or improvement of freight transportation services. One of the surveys to be conducted is the revealed preference (RP) survey. The important stage before the RP survey is to conduct a preliminary survey. This stage aims to determine the important trends related to the choice of modes by the forwarder and test the response rate of respondents. The survey is also useful for assessing the credibility of the data instrument, identifying potential errors in the data instrument, and determining non-conformities in survey management before the actual survey. Data collection was done by sending questionnaires. The structure of the questionnaire consists of questions about characteristics of : shipment, travel, and modes. The results of survey showed relatively low response rate because it was only 8 respondents who were willing to answer the questionnaire. This indicates that the questionnaire needs to be combined with other methods, such as: face to face interviews and or focus groups. The results of the preliminary survey show that the main factors for the choice of existing modes are: shipment costs, loss/damage, and time travel. The implementation of the next stage survey should consider that each company has more than one shipping commodity so it is necessary to group questions and analysis based on each commodity

Konsep Diri Individu Isteri Yang Direstui Menjadi Pekerja Seks Komersial Oleh Suami (Studi Fenomenologis Pekerja Seks Komersial Di Jatinegara)

Penelitian ini berfokus pada dinamika konsep diri individu isteri yang direstui menjadi PSK oleh suaminya. Bagaimana individu-individu PSK ini memaknai konsep-konsep sosial yang telah mereka kenai dan pahami sebelumnya sebelum menjadi PSK dan setelah menjadi PSK. Penelitian ini termasuk penelitian kualitatif dengan desain fenomenologis. Dalam penelitian ini, penulis melakukan wawancara bebas (tidak terstruktur) dengan maksud untuk melakukan studi mendalam (indepth study) pengalaman subjek penelitian. Penelitian ini dilakukan terhadap 4 orang subjek yaitu PSK yang biasa mangkal di daerah Pasar Enjo Jatinegara. Selain wawancara, dilakukan juga observasi di daerah Jatinegara dan sekitamya, yang merupakan tempat mangkal PSK baik PSK perempuan maupun PSK trans seksual. Dari analisis terhadap hasil wawancara, disimpulkan bahwa : Menjadi PSK adalah pilihan paling realistis bagi Subjek penelitian karena Jatar belakang pendidikan yang rendah dan kemampuan yang tidak memadai, sementara mereka membutuhkan pekerjaan yang menawarkan penghasilan yang besar. Telah terjadi pergeseran pemaknaan terhadap konsep-konsep sosial yang mereka pahami sebelum menjadi PSK dan sesudah menjadi PSK, dimana pemahaman konsep-konsep sosial mereka langgar karena alasan ekonomi. Telah terjadi inkongruensi (ketidaksejajaran) dalam pemahaman konsep sosial, mereka menganggap apa yang dilakukannya tidak sepenuhnya salah karena hal itu dilakukan dalam rangka mempertahankan hidup. Hasil penelitian meyarankan agar masyarakat terlibat dalam mengembalikan pemahaman PSK terhadap konsep-konsep sosial dengan memberikan sanksi sosial dan pemahaman agama kepada mereka. Selain itu pemerintah juga perlu turun tangan untuk menghilangkan tingkat komersial pekerjaan PSK yaitu dengan cara melarang atau melegalkan /lokalisir prostitusi

Multi-Object Face Recognition Using Local Binary Pattern Histogram and Haar Cascade Classifier on Low-Resolution Images

This study aims to build a face recognition prototype that can recognize multiple face objects within one frame. The proposed method uses a local binary pattern histogram and Haar cascade classifier on low-resolution images. The lowest data resolution used in this study was 76 × 76 pixels and the highest was 156 × 156 pixels. The face images were preprocessed using the histogram equalization and median filtering. The face recognition prototype proposed successfully recognized four face objects in one frame. The results obtained were comparable for local and real-time stream video data for testing. The RR obtained with the local data test was 99.67%, which indicates better performance in recognizing 75 frames for each object, compared to the 92.67% RR for the real-time data stream. In comparison to the results obtained in previous works, it can be concluded that the proposed method yields the highest RR of 99.67%
