Physical fitness is very important for athletes. It is because by knowing the physical fitness, an athlete can do excellent physical exercise, such as running exercises that can lead to physiological changes in athletes and physical fitness. Ganesha Sport Center (GSC) is a business unit developed by Universitas Pendidikan Ganesha (Undiksha), which is managed by the Faculty of Sport and Health (FOK). However, based on observations made by the research team to the GSC, tools for monitoring athlete's fitness, especially heartbeat are not available in the GSC. Based on discussions with GSC administrator, the need to develop a tool for monitoring the heartbeats of athletes, so that trainers can monitor athletes' condition, especially the athlete's heart condition. Based on this, it is deemed necessary to conduct research on the development of a tool to measure the heartbeats of athletes in the GSC. This research is an applied research in Science and Technology field to support sports facilities in GSC which is a business unit and also a lecture facility at Faculty of Sport and Health, Universitas Pendidikan Ganesha. Based on the result of Blackbox testing that has been carried out, the heartbeats measurement prototype development based on IoT can be declared successful and feasible to be implemented. Beside using blackbox testing, the prototype was also tested by measuring the sensor voltage requirements in measuring heart rate and temperature. From that test, it can be concluded that any increase in temperature or heart rate requires a greater voltage, and vice versa. This is because the sensor requires more power when the temperature or heart rate increases.

Group Audit and Risk Advisory (GAnRA) PT Astra International Tbk has several divisions; one of them is Risk Advisory (RA) Division. RA Division is responsible for data collection of the branches that affected by natural disasters to know the state of the branch after the disaster. But this time, the business process is running ineffective and inefficient. The meaning of ineffective here is when RA Division should call whole Sales Operation (SO) Head Office (HO) and affiliate company (affco) HO. While the meaning of inefficient here is when RA Division should pay the entire cost of the phone to call SO HO and affco HO. Therefore, RA Division requires an application that can predict the branches affected by natural disaster, namely Risk Dashboard. This application is developed by waterfall methodology, ASP.NET programming language, SQL Server Management Studio database, and Google Maps Geo-coding Technic. This application makes the time needed to find a branch to be only a few seconds from the previous one which took almost a day. With this application, it makes RA Division faster in analysing the data for reporting and updating Business Continuity Plan (BCP).

Tourism is a mainstay of Bali's original source of income. The object of tourist attraction in Bali is nature, culture, and a combination of nature and culture. Buleleng is located in the north of Bali. Besides being famous for its stunning underwater scenery, it also has cultural richness in the form of shadow puppet craft. The purpose of this study was to create an Augmented Reality (AR) -based application of shadow puppet characters which were the handicrafts from Nagasepaha village, Buleleng. This AR application uses smartphones as shadow puppet recognition media for children or young generation virtually. So, the process of introducing shadow puppet becomes more interesting and easy to use. Users can run the application, then the application performs marker tracking. If the marker matches the reference data contained in the application, the application displays the shadow puppets in 3D on the smartphone screen. The information displayed is the name of the shadow puppet character along with the accompanying attributes, animated shadow puppet, the voice of the puppeteer who describes the puppet character. The shadow puppet characters shown are from the Ramayana epic, namely Rama, Shita, Hanoman, Laksmana, and Rahwana. The presence of AR, it is expected to increase the love of the younger generation for shadow puppet artwork from the village of Nagesepaha which is an icon of cultural heritage from North Bali. The usability test is categorised good with the percentage is 84%. It's mean the program is running well and ready to use by end user.

This paper presents a smart system prototype, which is on an Arduino platform, to managing solar panels and batteries installed on grid in a household. The batteries here are as storage of surplus power produced by solar panels in supplying loads. The aim of employing a smart system is to reduce use of power consumption from grid maximally and to increase the lifetime of batteries. In the lab project experiment, we used some lamps with a 40 watt of the total of power to representing electric loads in a household and three power sources that are a power grid using PLN, a solar panel with a 50-watt power output, and a 100Ah Battery. All of the power sources and the load connect in parallel, and operate in DC circuits with 12 Volt of operational voltage. One of some testing, which was done about ten testing cases, showed that when the battery was in full charging, and the panel produced a maximum power, there was no power coming out from the grid to supply the loads instead the panel was solely supplying the loads. Employing a smart system to manage solar panels on grid gives a highly significant advantage because the system programmed can do complex controls.

This study aims to provide knowledge in order to save electricity consumption. The use of electrical energy is recorded at KWH meters. Saving electricity means limiting the use of electrical energy according to need. The use of electrical energy is based on the use of electrical power. Technically, this dimmer serves to regulate the use of electrical power. Some electrical equipment has been equipped with dimmers to regulate the operation of the equipment in accordance with the user's want, yet there are still many electrical equipment that is not equipped with dimmers. This is a problem in the efforts to save electricity. The method used in this study is applying passive components in electricity such as inductors, capacitors and resistors. These passive components are arranged to be used as filter circuits. With a 21 mH inductor with an air core, Farad's 12.5 micro capacitor, and 4.7 ohm resistor can be made as a passive filter that is installed before electric loads. The use of this filter circuit can save the use of electricity up to 15% at a load current of 2 amperes. Thus, electricity bill payments can be reduced by up to 15%. In the future, this research can be continued to improve the efficiency of electricity consumption by modifying passive filters.

Internship program is important to be implemented as it can increase the competence of the university students. In fact, the program gives significant impact to the success of the students in industry. Students freely choose their suitable place for the internship because suitable place will make students feel motivated and as a result they will be more competent. Industrial internship program is learning at the relevant industry, aimed to increase the competence of the students by introducing them with real working condition. Students are still find difficulty in deciding the suitable place for internship because of their low confidence or competence with related issue.

One of the important variables in developing software is users' satisfaction of the software. Hence, there is a need to measure users' satisfaction of the software's that have been developed. The measurement of the users' reactions covers some aspects such as users' satisfaction, ease of use, efficiency, and whether the systems that have been developed can meet the users' needs. This measurement is often called usability testing. It can be done using various instruments that have been developed by experts and communities in the field of computer. One of them is System Usability Scale (SUS). This article discusses an online peer assessment using usability testing. The instrument used was the usability scale system that was developed by John Brooke in 1986. The measurement using SUS yielded a mean score of 80.00. This mean score shows that the online peer assessment can be accepted and it can be categorized as grade B with Good rating. Hence, the online peer assessment is a feasible system.

This study aims to develop integrated tourism information portal prototypes in Bali by using web scrapping and Clustering methods.This study will use the waterfall development model. This study focused on the stages of needs analysis, system design for Tourism information portals in Bali and prototype development at the implementation stage. The initial stage of the web scrapping process is to do web searching in the form of url requests based on the keywords entered. After the data from the web scrapping process is collected, the next step is text processing which consists of several processes, namely parsing or tokenization, stemming in the form of root word search process, and stop word removal or removal of non-essential words. Before the clustering process begins, each word will be given weighting with the TF-IDF method which will form the vector space model as a representation of a text document. Similarity between vector space models will be calculated using the cosine similarity method. After the weighting process, the last step is to cluster the words which then continue to group the websites based on the results of clustering.The results of this study are a website portal that can display tourism information in Bali.

The environment has long been a medium of education. Children born in a fishing environment tend to be fishermen, children born in agricultural environments tend to be farmers, and so on. Education takes place informally in various social activities. Community members who are skilled at teaching community members who are not skilled or even just starting to study. Parents or other relatives, neighbours, and other community members can all be used as teachers. Surrounding nature is a medium of learning. The learning model is proven to be able to produce adequate skills, so that community members have sufficient life skills to make a living. Vocational education in modern education now prioritizes learning outcomes in the form of skills, so that graduates are ready to enter the workforce. Therefore, it is quite relevant if the traditional education model above is adopted for the vocational education system now. The approach used is to develop relevant vocational education in the existing environment. In the agricultural environment, an agricultural school is established, in a farm environment a farm school is established, or a fishery school is established, and so on. This vocational education model guarantees the relevance of competencies to work needs. In addition, vocational education like this guarantees the integration of skills, attitudes, and behaviour development processes, so that the competencies and characters possessed by graduates are more integrated. For existing vocational schools but not yet supported by a relevant environment, the approach that can be taken is to prepare a complete workshop in accordance with the skills they want to produce in the vocational education. Workshops can be expanded by building companies around schools that are engaged in fields that are relevant to the competencies built in schools.

The development of e-learning material is not only done once, but is carried out with repeated cycles. The cycle can simply be divided into 3 parts, including making, publishing, and reusing existing material. Various systems have been developed to support this cycle. Learning Management System (LMS) is the most common system used in e-learning. However, LMS alone cannot fully support the cycles mentioned earlier. Therefore, many other systems / applications are used to support the cycle. For example, a document processing application is used at the stage of making the learning material, then published to the LMS, search by using search engine and reused with specific authoring tools. In this article, we will discuss how to integrate several applications that support the development cycle of e-learning materials through an office application add-in. The add-in was used to integrate LMS and Learning Material Reconstruction System (LRMS) so that the entire development cycle of e-learning materials development can be done in one place.

Functionally, Assessment and Evaluation digital book based on kvisoft flipbook maker can attract students to read and make them easier to gain knowledge about the concepts of assessment and evaluation courses quickly whenever and wherever they are. Yet sometimes the material content contained in Assessment and Evaluation digital book is still not able to direct the mindset of students gradually from the basic level to high level. Therefore, Assessment and Evaluation digital book made using the kvisoft flipbook maker application, also needs to develop its content by adopting the superitem concept, so that it can improve students' thinking through the exploration of their mindset from simple to complex levels. Based on those problems, this research aims to provide an overview of the digital book content design for Assessment and Evaluation courses created with Kvisoft Flipbook Maker application by adopting the super item concept. The approach used was the development research with the Borg and Gall development design, which focuses on the stages of designing. The research subjects involved in this research were four experts to conduct an initial trial on the design of digital book content. They are two information technology education experts and two education evaluation experts. Data collection techniques were carried out by distributing questionnaires. The analytical technique used was descriptive statistics, by determining the percentage description. The results of this research indicated that a quality level in the design of digital book material content included in the good category.

This study aimed at determining whether the Interactive Mathematics Learning Media (IMLM) has a positive effect on hearing-impaired students' mathematical conceptual understanding (MCU) on probability. This research applied an experiment with post-test only control group design in which 36 students got involved. The intervention at the experimental group was learning assisted with IMLM. A descriptive approach of the qualitative phase was done toward some respondents which were selected purposively on the population. The MCU data was collected using an essay test. The MCU data were analyzed using one-tailed of t-test with the significance level of 5%. The result showed that using IMLM has a significant effect on students' MCU. Students in the experimental group were more motivated, more involved in learning because IMLM has accommodated their special needs namely the principle of facial orientation and visual representation compared with those in the conventional learning.

The use of e-Learning in education today is still conventional, which is still limited to the delivery of learning material and not yet fully managed as a learning management system (LMS) and assumes the characteristics of all students is homogeneous. In fact, every student has characteristics, especially different learning styles. Therefore, students who utilize e-Learning do not necessarily get the right material in learning, which results learning being less optimal. This research aimed to investigate the tendency of students' learning style which will be used as the base in designing an adaptive e-Learning system with Visual, Auditory, and Kinaesthetic (VAK) oriented, as one of solutions to increase learning quality. Survey method was used in this study on vocational students in Buleleng Regency. The sample of the study was determined by using stratified random sampling technique to determine 4 vocational schools (SMK) which have Computer Technique and Network department where the amount of students in each school was 30 students with 2 teachers who responsible to the subject related. The variable of this study was students' response to the questionnaire to identify the tendency of students' learning style with VAK oriented. The data were obtained from questionnaire, interview, and observation of students' learning process in classroom. The data was analysed descriptively. The result of the study showed that students' learning style tendency in adaptive e-Learning system design with VAK oriented on vocational students in Buleleng Regency was students tend to learn with Kinaesthetic style.

Subak is a traditional institution in Bali in charge of regulating irrigation systems for agricultural purposes. Management of irrigation systems includes maintenance of water sources, water drainage techniques, and water distribution. Subak has been passed down for generations since hundreds of years ago. The existing learning model in subak has been able to inherit technical skills and management ability to maintain the existence of subak. Considering these conditions, it is necessary to contextualize the learning model in the subak system to be applied in vocational education that emphasizes the mastery of skills. This study found that the learning model in the subak system was dominated by shared activities. The learning model is contextualized in vocational education into a model of shared cooperative learning. The learning model has been tested in the real class. The validity of the devaluation model by experts, while the practicality of the model is evaluated by teachers and students with user acceptance testing. Experts who evaluate the learning model provide recommendations that the learning model is relevant for vocational education. Meanwhile user acceptance testing for teacher and student shows that the learning model is quite relevan for vocational education. Student competency test results show that the learning model developed is quite effective. In addition to efficient in time and energy, the learning model gives more opportunities for students to show their potential to innovate.

This study aims to describe the implementation of project-based learning in Vocational High School (VHS) of Mechanical Engineering Expertise Competency in terms of planning, implementation, evaluation, and constraints. The study was carried out using qualitative descriptive methods. Research respondents were vocational teachers in the Mechanical Engineering Expertise Competency of the State VHS of Technology and Engineering in Malang City. The research data was collected using in-depth interview techniques, observation, and analysis of learning documents which were then analyzed qualitatively. The results show that vocational teachers have implemented PjBL both in terms of planning, implementation, and evaluation of learning. In projects planning the teachers have not involved the industries, the projects are relatively simple, so products of project cannot be utilized and not sold. The syntax of PjBL has not been seen in the implementation plan of learning but the implementation of practical learning at the workshop/laboratotium conducted by the teachers indicates the implementation of the PjBL syntax. Evaluation of learning outcomes in PjBL includes evaluation of processes and products. The main obstacle faced by teachers lies in determining the project, the preparation of the PjBL syntax, the limited practicum facilities in the school workshop/laboratorium, and the limited time for practicum.
