Introvert Students in a School
Abstract: The type of personality of adolescents can be discussed through the appearance of a form of treatment that either tends to be an extrovert, an introvert or an ambiver. This study examines introvert students. The theory of personality associated with this study is the Three Factors Theory (TTF) and the Psychosocial Theory. One aspect of the individual differences that is significant between one student and another is the personality aspect. Students with introverted personalities are individuals who are quiet, passive, over-thinking and under-performing and whose behaviors are less likely to take risks. The findings also show the various factors that lead a student to become an introvert - family factors, classroom environment, past history and nature. The introverted personality in these students affects them academically, co-curriculum and social. However, there are several approaches that can be taken to help these introverted students, for example through the role of the school. Another suggestion made by the respondents was the use of attractive teaching aids and 21st Century learning.

Smart Cane based on IoT
Get PDFGenerally, blind people use a traditional cane (known as white cane) for moving from one place to another. Although, white cane is the international symbol of blindness, it could not help them to detect place and to avoid obstacles. In this paper, we represent a model of walking stick for blind people. It consists of GPS module, GPS Antenna, Arduino, ultrasonic sensor and buzzer. This stick can detect place and obstacles. Position detection part is done with GPS module and GPS antenna. Ultrasonic sensor is used for detecting obstacles. Here, the buzzer produces two types of sound. When the blind reaches to his destination, buzzer buzzes continuously. When the blind faces any obstacles, buzzer buzzes with interruption. By discovering these two types of sound, blind can be confirmed about his destination and also can avoid obstacles in front of him. The whole system is designed to be small, light and is used in conjunction with the white cane so that it could ensure safety of the blind
Sistem Pendukung Keputusan Pemilihan Guru Terbaik di SMK Pustek Serpong
Get PDFDalam upaya meningkatkan mutu pendidikan untuk para siswa sebagai generasi penerus bangsa dibutuhkan guru yang berkompeten dalam memberikan pendidikan kepada siswa. Sistem Pendukung Keputusan di dunia Pendidikan dipandang sebagai aset penting untuk menunjang kelancaran dan keakuratan dalam pencapaian suatu tujuan. SMK Pustek Serpong belum memiliki sistem pendukung keputusan untuk membantu Kepala Sekolah dalam melakukan pemilihan guru terbaik, pengambilan keputusan secara manual akan menghasilkan penilaian yang tidak objektif sehingga tidak tepat. Oleh karena itu, penggunaan metode TOPSIS dapat bermanfaat dalam mendukung sistem pengambilan keputusan dikarenakan metode ini dapat mendukung penilaian kriteria seperti absensi, perilaku, disiplin, kemampuan mengajar dan tanggungjawab guru serta pembobotan nilai. TOPSIS menggunakan prinsip bahwa alternatif terpilih harus mempunyai jarak terdekat dari solusi ideal positif dan jarak terpanjang dari solusi ideal negatif untuk menentukan kedekatan relatif dari suatu alternatif dengan solusi optimal. Hasil yang dicapai dari sistem pendukung keputusan ini adalah sistem ini terbukti dapat membantu SMK Pustek Serpong dalam melakukan pemilihan guru terbaik, penerapan metode TOPSIS terbukti dapat membantu Kepala Sekolah dalam pengambilan keputusan pemilihan guru terbaik.
Decision Support System for Selection of the Best Teachers in SMK. Pustek Serpong
Abstract: In an effort to improve the quality of education for students as needed future generation of teachers who are competent in providing education to students. Decision support system (DSS) in the world of education can be seen as an important asset to support the smoothness and accuracy in achieving a goal. SMK Pustek Serpong does not yet have a decision support system to assist principals in the selection of the best teachers, decision making manually will result in an objective assessment that is not appropriate. The use of TOPSIS method in the decision support system is because this method strongly support the assessment of criteria such as absenteeism, attitude, and discipline, teaching ability, and teacher responsibilities, and weighting the value of. TOPSIS uses the principle that the chosen alternative must have the shortest distance from the ideal solution and longest distance from the ideal negative solution to determine the relative proximity of an alternative to the optimal solution. The results archieved from this decision support system is that this system is proven to help SMK Pustek Serpong in the selection of the best teachers, the application of TOPSIS method is proven to help principals in making the best teacher selection decisions.

Optimizing K-Means Initial Number of Cluster Based Heuristic Approach: Literature Review Analysis Perspective
Get PDFOne popular clustering technique - the K-means widely use in educational scope to clustering and mapping document, data, and user performance in skill. K-means clustering is one of the classical and most widely used clustering algorithms shows its efficiency in many traditional applications its defect appears obviously when the data set to become much more complicated. Based on some research on K-means algorithm shows that Number of a cluster of K-means cannot easily be specified in much real-world application, several algorithms requiring the number of cluster as a parameter cannot be effectively employed. The aim of this paper describes the perspective K-means problems underlying research. Literature analysis of previous studies suggesting that selection of the number of clusters randomly cause problems such as suitable producing globular cluster, less efficient if as the number of cluster grow K-means clustering becomes untenable. From those literature reviews, the heuristic optimization will be approached to solve an initial number of cluster randomly
Sistem Pakar Diagnosa Penyakit Ginjal

Sistem tersebut mampu memberikan pelayanan kepada masyarakat dan penyampaian informasi yang berkaitan dengan penyakit ginjal. Pada penelitian ini pengumpulan data dilakukan dengan menggunakan metode observasi dan studi pustaka. Hasil penelitian ini menunjukkan bahwa dengan adanya sistem pakar diagnosa penyakit ginjal pada manusia, dapat memberikan manfaat yang cukup berarti antara lain proses pengolahan data dan proses konsultasi dilakukan dengan cepat serta menghasilkan laporan yang cukup akurat, sehingga membuat pekerjaan akan lebih efektif dan efisien.
Expert System for Diagnosing Kidney Diseases
Abstract: The weather station helps in planning socioeconomic activities Kidney is an important organ in the body's metabolic system. The amount of activity a person will affect kidney health if the organ is not maintained. Irregular eating patterns, lack of fiber and mineral water intake, and consumption of instant high-calorie foods or drinks will aggravate the kidney's work starting from the process of filtration, reabsorption, until augmentation of food substances below the kidneys through the blood. The purpose of this study is to create an expert system for kidney disease using the Eclipse Juno programming language. The system is able to provide services to the community and delivery of information related to kidney disease. In this study data collection was carried out using observation and literature study methods. The results of this study indicate that with an expert system of diagnosing kidney disease in humans, it can provide significant benefits including data processing and consultation processes carried out quickly and produce reports that are quite accurate, so as to make the work more effective and efficient

Smart Charger Based on IoT Concept
Get PDFThis research develops Arduino based smart charging controlling. The aim is to develop a charging that can be controlled by setting the charger in a specific time. Therefore, the problem of overcharging will be anticipated. This research using the AA type of rechargeable battery, Nickel-Metal Hydride (NiMH). C++ is being used for the Arduino. Arduino was chosen for this research because the Arduino boards are able to read inputs – light on a sensor or finger on a button – and turn it into output by activating a motor, turning on an LED, publishing something online. The result of this research is it has succeeded in creating the smart charger that can ensure the safety of the battery by controlling the amount of time in the charging process. The charging will be stopped if the time has reached the limit or if the temperature is high. Indeed, the research will inform the user whether the battery has been full charge or not
