<![CDATA[Steel reinforcement is well known as an important component in forming building structures. However, as the community's need for reinforcing steel is increasing, the main material for forming steel reinforcement is decreasing so that the price is getting higher. The alternative that is suggested as a substitute for tensile steel reinforcement which is economical and easy to get is bamboo. The purpose of this study was to determine the ratio of beam bending using circular and square bamboo reinforcement and to determine the bending load that can be accepted by circular and square bamboo reinforcement. In this study an experimental method was used by conducting a series of tests ranging from preserving bamboo and testing aggregates as a building block for concrete. The cross sections of bamboo reinforcement used are square and circle shapes with a diameter of 10mm with beam dimensions of 900 mm x 150 mm x 150 mm. The results showed that the flexural strength produced by steel reinforcing concrete beam was 11,36 MPa, circular cross section bamboo reinforcing beam 8,73 MPa and rectangle cross section bamboo reinforcing concrete beam of 9,04 MPa.]]>

<![CDATA[Sistem multi-robot telah diterapkan pada tugas-tugas kompleks yang biasanya dilakukan oleh manusia. Untuk dapat menjalankan tugasnya, robot perlu bernavigasi ke dari suatu posisi ke posisi lain. Agar dapat bernavigasi dengan baik, robot memerlukan peta sebagai acuannya dalam bernavigasi. Simultaneous Localization and Mapping (SLAM) merupakan sebuah metode bagi robot untuk dapat membuat peta dan melakukan lokalisasi. ORB SLAM-2 merupakan sebuah metode SLAM berbasis sensor visual yang kompatibel terhadap kamera monokular, stereo, maupun RGBD. Dengan menggunakan kamera monokular, penelitian ini bertujuan untuk membuat rancangan sistem pemetaan lingkungan multi-robot dengan menggunakan algoritma ORB SLAM-2. Tugas akhir ini merancang sistem desentralisasi sehingga algoritma dijalankan pada kedua robot. Kemudian setiap robot melakukan pemetaan lingkungannya dan mengirimkannya ke komputer agar dapat divisualisasi. Pada percobaannya, rancangan ini berhasil membuat sistem melaksanakan tugasnya dengan baik. Peta yang dihasilkan oleh sistem ini memiliki skala sekitar 1 : 5,81. Sistem juga dapat memvisualisasikan peta yang dihasilkan oleh masing-masing robot pada sebuah komputer server. Berdasarkan hasil percobaan, dapat disimpulkan bahwa sistem pemetaan lingkungan multi-robot menggunakan ORB SLAM-2 dapat dilakukan dengan mendesentralisasi sistem. Dengan ini, beban kerja sistem terbagi menjadi dua, pertama pemrosesan gambar dilakukan oleh masing-masing robot hingga menghasilkan titik-titik peta dan kedua komputer server bertugas untuk memvisualisasikan titik-titik peta yang dihasilkan robot pada antarmuka pengguna.]]>

<![CDATA[Workers who can control electric motors are currently needed. Therefore, knowledge about controlling electric motors should be taught in vocational high schools. Installation and control of electric motors in the industry are generally used in various devices related to the production process such as controlling the motor driving conveyor belts, controlling pumps on factory pipes, and controlling freight elevators. The problem that arises is the lack of knowledge about electric motor control in vocational school teachers and insufficient facilities for the learning process of electric motor control. Also, Vocational High School (SMK) has not been able to change the old learning patterns to the new learning patterns required in the 2013 curriculum. One of the changes in the curriculum is a change from teacher-centered learning to student-centered learning. In this service program, learning the installation and control of electric motors in the simulator of elevators was developed using the Problem Based Learning (PBL) approach for students of SMKN 1 Cipatat. The first step in implementing this program is to study the curriculum and syllabus applied to the two partner vocational schools, then design a learning process for the installation and control of electric motors using the PBL method. The PBL method was chosen because this method can simultaneously be used to increase students' soft skills such as the ability to innovate, discipline, and the ability to convey ideas both in writing and orally. Besides, the PBL method can also support changes to learning patterns as required in the 2013 curriculum.]]>

<![CDATA[One of the causes of accidents on trains to date has been caused by damage of railways such as cracked rails, broken rails and other rail defects. Currently, the inspection of the railway line is still carried out manually by the railway inspection officer or Petugas Penilik Jalan Rel (PPJ). However, there is a prototype Autonomous Railways Monitoring Robot (ARMR) which is a prototype inspection robot that can perform rail line checks automatically and be monitored remotely to detect any faults on the railway. The ARMR prototype detects faults as well as locations that are subsequently delivered to users by utilizing some Internet of Things (IoT) features. Faults detected by ARMR prototypes are faults as rail damage. But, the ARMR prototype is unable to distinguish a fault and rail connection. This final task aims to improve armr prototype capabilities to produce information in the form of depth and width of faults, and to distinguish faults and rail connections. The VL6180X sensor is a laser- based distance sensor used as a depth detector for rail faults and rail connections. The Incremental Encoder is enabled to measure the width of the rail fault. The result of ten experiments at 20 cm/s, the ARMR prototype was able to produce 78 mm fault depth size information with an error value of 1,67%, produce 5 mm wide fault width information with an error value of 2,48 % and be able to distinguish faults and connections with 72 % accuracy for the comparison of the distance between the ARMR prototype and the distance shown on google maps.]]>

<![CDATA[Renewable energy from solar cells is a type of alternative energy for consumers, especially those far from electricity, and saves electrical energy. This research developed an innovative tool for portable solar power generators as a source of energy, which stores electrical energy in two ways, namely solar cells and transformers. Furthermore, this research is expected to improve innovation tools for more efficient electricity supply and energy use, especially for rural communities. It also uses a variety of battery capacities to test portable power supplies. The results showed that the power supply using 100 Wp solar cells produced a capacity of 20 Ah, 60 Ah, and 100 Ah on the battery. Charging with a solar energy source on a 20 Ah battery takes a duration of 5 hours to be fully charged, while 60 Ah and 100 Ah batteries cannot be fully charged in one day. Charging a battery that has been run at a full level takes a duration of 15 hours at a temperature of 30oC to 34oC. Finally, this tool is expected to add variety to locally manufactured products.]]>

<![CDATA[One of the problems in improving the competence of Information and Communication Technology (ICT) for mathematics teachers is that the teacher has to leave his / her teaching activities to participate in various improving competence events. This study aims to develop an ICT house portal that will be managed by the Mathematics Subject Teacher Forum in Indonesia or known as MGMP that allows teachers to interact with fellow teacher communities to improve ICT competence without having to leave their teaching activities at school. Furthermore, the researchers also conducted a usability test of the developed portal. The application development model used is the ADDIE model which stands for Analysis, Design, Development, Implementation, Evaluation. Meanwhile, application usability testing was carried out by distributing usability questionnaires to 30 respondents consisting of postgraduate students and lecturers of mathematics education. The results showed that the ADDIE model can be used to design and create the ICT house portal called RumahTIK where the procedures in the development section include making applications, testing by experts, testing content filling, testing the use of clinical features. Based on the results of the usability questionnaire processing, the percentage of usability was 81% which was classified as very feasible. Although this research was not implemented for real teacher groups, the ICT house portal is very suitable for use by the MGMP group. In the future, it is necessary to implement this portal in various MGMP groups so that recommendations can be obtained to improve teachers' ICT competence in mathematics.]]>
