Tracer study is a mean to gather information of the alumni on regards to learn about their progress in career, their implementation of skills they learn in their study, and opinion about them from people who work alongside them. The importance of tracer study lies in the processing data from the alumni and producing information that can be used to increase the learning materials, learning methods, motivation of the current students, and quality of service given by the university. Collecting data from graduated University students is not an easy task. The major issue in the data gathering is the distance between the University and the data giversâ€™ location because most of them are not grouped in areas near the campus which make them unable to directly submit the questionere to the faculty they studied. Other dificulties faced by the university which conduct tracer study are the alumniâ€™s ocupation which prohibit them for going to University, time limit given for the alumni to submit their form, cost used for buying and printing papers, more over the formâ€™s layout and content that consist of things that need to be skipped based on options the participantâ€™s choice which make it confusing and dificult to gather valid data.The result of this research is an aplication that can handle the inputs of tracer study by the alumni and produce information about alumniâ€™s progress from those inputs, especialy for those who had graduated from their alma mater for more than six months.Â Several improvement that can be achieved by this application caompared to the previous hand in form method are instant collecting as soon as the user press the submit button, automatic processing which can eliminate submision due date because the user can fill the form any time there is a change in their data, and automatic text and graphical reporting which can be seen anytime with real time update which can be used for producing data for decision making in the university where this application is used.Keyword : angket, alumni, UNWAHA, tracer study, online

One of the computer-based testing is the Computerized Adaptive Test (CAT), which is a computer-based testing system where the items were given to the participants adapted to test the ability of the participants. Assessment methods are usually applied in CAT is Item Response Theory (IRT). IRT models are most commonly used today is the model 3 Parameter Logistic (3PL), which is about the discrimination, difficulty and guessing. However 3PL IRT models have not provided information more objectively test the ability of participants. The opinion of the test participants were tested items were also to be considered. In this study using CAT in combination with IRT model of 4PL.In this research, the development of CAT which uses about 4 parameters, namely the discrimination, difficulty, guessing and questionnaires. The questions used were about UAS 1 English subjects. Samples were taken from 40 students answer with the best value of the total 172 students spread across 6 classes to measure the parameter estimation problem. Further testing using CAT application 4PL IRT models compared to CAT 3PL IRT models.From research done shows that the CAT application combined with IRT models 4PL can measure the ability of the test taker shorter or faster and also opportunities participants correctly answered the test items was done tend to be better than the 3PL IRT models.Â Keywords : Ability, CAT, IRT, 3PL, 4PL, Probability, TestÂ

Potensi sumber daya air di Indonesia sangat melimpah, tetapi ketersediaan air sangat bervariasi berdasarkan dimensi ruang dan waktu. Adanya perubahan iklim, kerusakan ekosistem dan perubahan penggunaan lahan di Daerah Tangkapan Air (DTA) mengakibatkan terjadinya krisis air di musim kemarau. Penelitian ini bertujuan untuk menganalisis komposisi dan struktur vegetasi pohon dalam peranannya sebagai salah satu bentuk konservasi air. Analisis vegetasi secara ekologis yaitu Jenis tumbuhan, Densitas, Frekuensi, Luas basal area, INP, dan Indeks Keanekaragaman. Penelitian ini dilaksanakan pada bulan November 2015-April 2016 di DTA mata air Geger. Metode pengambilan sampel adalah metode kuadrat plot secara acak.Â Penentuan DTA yaitu berdasarkan Citra Quikbird untuk pembagian kelas vegetasi. Selain itu, dilakukan pengukuran kadar lengas tanah dan fisiko kimia. Hasil penelitian menunjukkan bahwa luas area DTA mata air Geger secara keseluruhan berdasarkan kelas vegetasi yaitu 9875.26 ha. Jumlah individu spesies terbanyak yang ditemukan dari masing-masing kelas vegetasi secara berturut-turut yaitu Swietania mahagoni, (L.) Jacq; Tectona grandis, L. Acacia auriculiformis A. Cunn Ex Benth; Tectona grandis, L. dan Gnetum gnemon, L. Indeks Nilai Penting (INP) tertinggi dari masing-masing kelas vegetasi yaitu Swietania mahagoni, (L.)
