AbstrakPenelitian ini bermaksud untuk memperoleh hasil peningkatan kemampuan Koneksi matematik dan self efficacy melalui pembelajaran Model CORE, selain itu untuk melihat respon mahasiswa terhadap belajar matematik dengan model CORE. Pelaksanaan penelitian ini berbentuk quasi eksperimen dengan membandingkan prestasi belajar mahasiswa melalui model CORE dengan mahasiswa yang memperoleh pembelajaran konvensional. Populasi berasal dari mahasiswa Fakultas Teknik di Perguruan Tinggi di Garut dengan sampel penelitiannya berjumlah 54 mahasiswa. Dengan 27 orang diberi pembelajaran dengan model CORE dan 27 lainnya melalui pembelajaran konvensional. Dalam pengambilan data digunakan Instrumen berupa tes matematik, angket model CORE dan angket self efficacy. Hasil yang didapat yaitu: 1) Peningkatan Koneksi matematik mahasiswa yang mendapatkan pembelajaran dengan model CORE lebih baik dari pada mahasiswa yang memperoleh pembelajaran konvensional. 2) Self efficacy mahasiswa yang mendapatkan pembelajaran dengan model CORE peningkatannya tidak lebih baik dari pada mahasiswa yang memperoleh pembelajaran konvensional. 3) Terdapat hubungan antara model CORE dengan Self efficacy dalam kategori sedang. 4) Mahasiswa memberikan kesan yang positif terhadap model CORE. Improving Mathematical Connection Ability and Self Efficacy Students through Core-Based ModelsAbstractThis study aims to obtain the results of increasing the ability of mathematical connections and self-efficacy through learning the CORE Model, in addition to seeing student responses to learning mathematics with the CORE model. The implementation of this research is in the form of a quasi-experiment by comparing student learning achievement through the CORE model with students who receive conventional learning. The population came from students of the Faculty of Engineering at Higher Education in Garut with a research sample of 54 students. With 27 people being taught using the CORE model and 27 others through conventional learning. In collecting the data, instruments were used in the form of a mathematical test, a CORE model questionnaire, and a self-efficacy questionnaire. The results obtained are: 1) Increased mathematical connection of students who get learning with the CORE model is better than students who receive conventional learning. 2) The increase in self-efficacy of students who get learning with the CORE model is not better than students who get conventional learning. 3) There is a relationship between the CORE model and Self-efficacy in the medium category. 4) Students give a positive impression on the CORE model.

Parameter merupakan salah satu materi perkuliahan yang dipelajari dalam mata kuliah mata kuliah Elektronika Telekomunikasi. Materi S-Paremeter merupakan materi yang cukup sulit dikarenakan mahasiswa menggabungkan cara perhitungan dari polar ke rectangular atau sebaliknya dari rectangular ke polar. Beberapa nilai yang dihitung dalam materi S-Parameter adalah koefisien pantul source (S), koefisien pantul loud (L), koefisien pantul input (IN), koefisien pantul output (OUT), tranducer power gain (GT), available power gain (GA), operating power gain (GP), delta factor, factor kemantapan (K), jari-jari source (RS), titik pusat source (CS), jari-jari loud (RL), dan titik pusat loud (CL). Metode yang dipakai dalam penelitian ini adalah metode prototype, sehingga didapat aplikasi S-Parameter yang berbasis android.

An availability of a parking place in the shopping centre remains becoming a problem since the vehicles often enter the parking area without being sure about the available parking space left in the parking lot. This research was intended to design information system regarding the availability of parking place for the vehicles when entrancing the shopping centre. Through this information system, the entering vehicles will just need to go to the available parking place. This research employed prototyping method by using microcontroller as input data processor, Inductive Proximity sensor, Wi-Fi module, and Web application. When vehicles come into the parking lot A, the sensor will provide the data on the Arduino about the available parking place in the parking area A, and then the data will be sent to the Web application by using Module Wi-Fi so that the web for the parking place A will get information about the availability and the unavailability of the parking place in that parking area. There will be also a description about the available parking place on the other parking places such as in the parking lots B and C. Through this research, the parking place for the vehicles will be more well-organized and the vehicles will be eased to look for an available parking space when they go into the shopping centre.

The complexity of electrical installation in a building will depend on the function or operation of the building in question. On the other hand, power supply is very important to support the building operation. However, it is very often difficult to locate which point in the power distribution system that experience electrical fault. This study attempts to solve such problem by designing a prototype of monitoring and controlling system of power distribution in school buildings. To this end, we use Arduino-based system and Wonderware InTouch for the user interface. This study resulted in a power monitoring system consisting of voltage sensor and electric relay connected to Arduino ATMEGA 2560. The system can be configured, monitored and controlled through a computer software.
