Abstrak— Teknologi informasi hampir tidak dapat dilepaskan dari berbagai aspek kehidupan manusia, dikarenakan kemudahan untuk mengakses informasi adalah salah satu pemanfaatannya. Minimnya pakar tumbuhan dan pengetahuan petani dalam menangani penyakit pada tanaman mentimun menyebabkan kerugian bagi petani khususnya petani mentimun. Selain daripada itu hal ini juga menjadi hambatan bagi para petani mentimun untuk mendiagnosa dan melakukan penanganan yang tepat terhadap penyakit mentimun yang menyerang tanaman yang mereka tanam. Petani kurang paham terhadap jenis penyakit pada tanaman mentimun, sehingga lambatnya proses penanganan pada tanaman mentimun. Dempster-Shafer dikenal adanya Frame of Discrement yang dinotasikan dengan dengan θ. Frame ini merupakan semesta pembicaraan dari sekumpulan hipotesis.Sistem pakar umumnya didefinisikan sebagai sebuah sistem yang dirancang untuk memodelkan kemampuan menyelesaikan masalah seperti layaknya seorang pakar (human expert). Identifikasi masalah dalam penelitian ini yaitu kerusakan pada tanaman mentimun akibat sulitnya mengidentifikasi penyakit pada tanaman mentimun. ruang lingkup/batasan masalah dalam penelitian ini Data penyakit yang akan diteliti sebanyak 6 penyakit, data gejala yang akan diteliti sebanyak 12 gejala. Metode yang digunakan dalam mendiagnose penyakit pada tanaman mentimun ialah metode Dempster Shafer. Aplikasi yang digunakan adalah aplikasi Adobe Animate CC. Database yang digunakan adalah SQLite.Kata kunci: Penyakit Timun, Android, Sistem Pakar, Dempster Shafer Abstract— Information technology can hardly be separated from various aspects of human life, because the ease of accessing information is one of its uses. Farmers do not understand the types of diseases in cucumber plants, so the process of handling cucumber plants is slow. Dempster-Shafer is known for its Frame of Discrement which is denoted by θ. This frame is a universe of discussion from a set of hypotheses. An expert system is generally defined as a system designed to model problem-solving abilities like a human expert. Identification of the problem in this study is damage to cucumber plants due to the difficulty of identifying diseases in cucumber plants. the scope / limitation of the problem in this study. The disease data to be studied were 6 diseases, the symptom data to be studied were 12 symptoms. The method used in diagnosing diseases in cucumber plants is the Dempster Shafer method. The application used is the Adobe Animate CC application. The database used is SQLite.Keywords: Cucumber Disease, Android, Expert System, Dempster Shafer

Expert system is a computer program which is designed for modelling the ability of problem solving as it is an expert (human expert). The expert system method used is the forward chaining method which is the inference method that is doing logical reasoning from the problem to its solution. The aim of this research is to design and develop an expert system that is able to identify the severe malnutrition on children from the age of 0 - 5 years old. The knowledge is derived from the question askedto a nutrition expert. The data are taken from the questions asked to the user and when all of the questions has been answered, then the goal will be appeared which shows the nutrition status. This system application will enable the user to diagnose the nutrition/disease that affects children and get the solution. This system can be used by any kind of user due to the easy access. This system is also put the important information about the severe malnutrition and the recent news of children’s health so it will add more knowledge for the parents about the importance of severe malnutrition’s prevention.

Knowledge acquisition is the first step in building an expert system. However, it is very difficult to find out the problem-solving approaches from a human expert completely and correctly. Here we implemented the Think-aloud experiment with an expert in architecture. By coding and analyzing the designing process, other researchers could proceed our research and find out the cognitive models corresponded to the approaches and strategies of how experts solved the problems encountered during the normal designing process.

Expert systems are one of the most exciting and promising applications of computers. An expert system (ES) is an intelligent computer system that contains an organized body of knowledge and emulates an expert problem solving skills. It is designed to emulate the decision-making ability of a human expert. This paper provides a primer on expert systems, their features, applications, benefits, and challenges.

The development of increasingly advanced information technology can provide many benefits for completing work quickly and accurately. One example that requires the delivery of information quickly and accurately is the field of library, this is in accordance with the function of the library which is the heart of education. Most libraries are still many who adhere to a conventional system, of course this will result in disruption of the continuity of the process of managing books in the library. Therefore, the author takes the theme of this study regarding Library Book Management Information Systems Based on Websites by using the waterfall method on software development as well as methods of observation and literature on data collection. This Information System is the best solution for problem solving in managing library books. With the use of managed computer data technology becomes faster, reducing inefficient time and reducing the occurrence of errors in processing data.

Penelitian ini bertujuan menguji pengaruh model PBL terhadap kemampuan pemecahan masalah geografi SMA. Penelitian dilakukan di SMA Negeri 1 Sooko tahun ajaran 2015/2016. Subjek penelitian merupakan siswa kelas XI IPS 2 dan 3. Penelitian ini merupakan penelitian eksperimen semu (quasi experiment) dengan desain Non Equivalent Control Group Design. Berdasarkan selisih nilai pre test dan post test, rata-rata gain score kemampuan pemecahan masalah geografi SMA kelas eksperimen lebih tinggi dengan skor 27,26 dibandingkan dengan kelas kontrol dengan skor 11,88. Hasil perhitungan analisis uji t menggunakan independen sample t test diperoleh data p-level lebih kecil dari 0,05 (p<0,05) yaitu 0,00. Hasil perhitungan ini membuktikan bahwa model PBL berpengaruh terhadap kemampuan pemecahan masalah geografi SMA. Jadi, dapat disimpulkan bahwa model PBL berpengaruh terhadap kemampuan pemecahan masalah geografi SMAN 1 Sooko.Kata Kunci: Model Problem Based Learning, Kemampuan Pemecahan MasalahThe purpose of this study was to clarify the effect of the PBL model of problem-solving ability. This study do in SMA Negeri 1 Sooko 2015/2016. Study of the subject is the student of class XI IPS 2 dan 3. Form of quasi-experimental research design with non equivalent design control group. Subjects were selected based on the value of Middle Exam School (UTS) semester who have the same average (homogeneous). Control using a model class lectures and discussions, while the experimental class using PBL models. Gain score Data were analyzed using independent sample T-test Test with the help of the computer program SPSS 16.0 for Windows. Gainscore learning using PBL model of higher than conventional. The average value of the experiment gainscore class of 27, 26 and 11.88 of control. The results of the analysis of the Independent Sample T-Test Test, the difference shows a p-value of 0.000 level. The level of p-value less than 0.05 (P <0.05). The results of this study there was a significant effect PBL models to the problem-solving abilities. So the conclusion "PBL model significantly influential to the high school geography problem solving skills in SMAN 1 Sooko".Key Words: models of PBL, problem-solving abilities
