The low standard of values ​​for natural science shows that Indonesia is still lagging behind other countries. This can be seen from the data from the results of the PISA survey conducted by the OECD in 2003 which states that the standard for Natural Sciences in Indonesia is 360.16, while the standard for Natural Sciences (IPA) in the world is 484.84. This data shows that the average score of Natural Sciences subjects is still very low. There are many factors that underlie the low value of IPA in Indonesia. one of them is the assumption that this subject is difficult. In addition, students also find this subject boring and uninteresting. Therefore, this study intends to develop alternative media for fifth grade students to help them learn science, namely in the form of an RPG game that can be played via a computer.

The existence of Marana geothermal manifestations of hot springs scattered in Masaingi Sub-district, Donggala District, Central Sulawesi Province, indicates geothermal prospect zone. Therefore, in order to obtain the subsurface model and to interpret the prospect zone, has been conducted an interpretation of Marana geothermal subsurface area based on magnetic anomaly data. The research uses secondary data of magnetic anomaly obtained from Centre for Geological Resources, Bandung, Indonesia. The research area is located on UTM zone system 50 which close to the magnetic equator, therefore the reduction to equator (RTE) process is applied to the IGRF corrected dan diurnal variations. The Upward Continuation is conducted to obtain a regional magnetic anomaly on 600 meters. Furthermore, 2.5-dimensional modeling on subsurface had done by the Talwani method using Software Oasis Montaj. The 2.5-dimensional modeling results show that the contrast of magnetic susceptibility value of Marana Geothermal rocks. Medium magnetic susceptibility value are metamorphic rock complex and Tinombo Alhburg Formation with values ranging from 0,69-0,8 (x10-2SI). Formation of Molasa Celebes Sarasin and Sarasin have low magnetic susceptibility with values 0,007-0,01 (x10-2SI), whereas high magnetic susceptibility value are granite and granodiorite (1,2x10-2SI). The new intrusion is found in the body of granite and granodiorite with magnetic susceptibility value 2,1 (x10-2SI). Based on the result of Marana geothermal modelling, the prospect zone (reservoir) is estimated in the West of research area which near the Masaingi hot spring. The prospect zone is estimated to be sandstone at a depth of ± 1200 metre. The heat source is the new intrusion thought to be a heat source (diorite) with a depth of> 4500 m. Clay cap is predicted to be an altered sandstone of argillitic alteration. The Masaingi hot spring is indicated to be an upflow zone just above the heat source, while the outflow zone is estimated to be in the southern of the research area.

Increasing technological developments require many parties to always adjust to all kinds of changes that will occur in the future, both economic conditions, government regulations, consumer conditions, and conditions of competitors. The way companies communicate with their investors has also changed, as a result of the rapid development of the internet. The internet that companies use to report financial information to investors is called Internet Financial Reporting (IFR). Today, IFR has been put forward by most countries because it can minimize the negative effects of information asymmetry, reduce agency costs, reduce capital costs, and increase firm value. Companies in achieving their goals are faced with uncertain conditions. The purpose of this study is to find out how the differences between IFR and ERM in commercial banks in Indonesia with high and low market capitalization values. This research is a non-static analytical descriptive study. The sample used is only two commercial banks to be compared. The results of the comparative analysis carried out showed that there was no significant difference in the implementation of IFR, but in the implementation of ERM there were significant differences.  

The development of information and communication technology in the current digital era is growing very rapidly and affects many aspects of human life, including aspects of children's education. The influence of these technological developments also brings changes to modern lifestyles that have both positive and negative impacts on all levels of society, including the lives of children. The COVID-19 pandemic that has occurred since 2020 also affected the life of the education world, namely changing learning methods of the teaching and learning process in schools. The online learning method is starting to be applied for schools that are ready with this online learning system, which requires a lot of media, such as cellphones, laptops, computers and of course the availability of a good internet network. This government policy came into effect in several provinces in Indonesia on Monday, March 16, 2020, which was also followed by other provincial areas. The changing era and the influence of the development of technology and information can affect children's lives. These are a challenge for a teacher because the teacher's role is very important in the child's education process. This role can be interpreted as individual behavior that is important for the social structure of society. While facing all challenges, the teacher has important role to instill the right character values for students to anticipate all negative influences that can be caused and affect their lives, especially for PAK teachers in carrying out their main duties.

This research report is motivated by the large number of sharia financial institutions that have emerged and the increasing number of sharia banks that provide financial services while meeting the increasingly diverse needs of society. With the current abundance of sharia banking, there are accusations that sharia banking is a conventional bank that only has a sharia label attached to it. However, nowadays sharia banks always try to implement Islamic values based on Sharia principles. Sharia banking has a big influence on people's economic activities. Various sharia banking products are expected to be able to encourage and accelerate people's economic progress in accordance with Islamic principles. In Islamic principles, economic activity cannot be separated from the postulate of faith in Allah SWT and even becomes a built in control for economic actors. From here, sharia banking was built and designed to improve the standard of human life. Sharia banking is expected to become an alternative and even a decisive solution for the development of the national economy, especially for Muslims.

Improvement of Textile Industry system design with Six Sigma and FMEA to improve process quality. Six Sigma is a method of continuous quality improvement, by minimizing the number of defects. FMEA (Failure Mode Effect Analysis) tool is used to help determine the appropriate action, eliminating priority failure modes. The next step to improve to determine the most influential factor to the occurrence of color defects, so that the influence of the interference factor is minimum. If the control function is carried out and the factors causing the defect do not appear again there will be an increase in sigma value. FMEA analysis results obtained by machine temperature and material factors that most influence the occurrence of color defects, with RPN values of 210 and 120 respectively, the Six Sigma calculation results an increase in sigma value from initial conditions of 3.78 sigma to 4.93 sigma, or an increase in process capability of 1.15 sigma. Proposed improvements with DOE so that color defects do not appear are suggested by setting the thermosol engine temperature control device and mixing the optimized NaCl.

Marriage is one of the many religious rituals carried out with the aim of creating a family. In rural communities that are full of traditional values, marriage is not only carried out according to procedures or regulations in accordance with religious regulations. In this case it is the Islamic religion. One of the most important things in organizing a marriage is the presence of a dowry. The dowry is identical to the binding of the groom to the bride who becomes his wife. Islamic law does not set a limit on the amount of the dowry, because the most important thing is the wife's acceptance of her husband's gift. Karduluk village, which was the location of this research, gave dowries in the form of household items ranging from cupboards, cots/beds, chairs and tables, decorative cupboards, and so on. These items are brought to the bride's house during the wedding and are considered part of the dowry.

Recent technological developments determine humans to be creative in creating tools that implement technology in it with the aim of facilitating human tasks in daily activities. Inappropriate use of fertilizers can cause losses, both losses on fertilizer, on plants, as well as on the soil and the environment around fertilization. Losses on plants such as unhealthy plant growth and susceptible to disease pests, plant yields are not as expected or low. From the background above, the writer found an idea to create a system or tool that can help farmers in determining the dose of Nitrogen fertilizer in their rice plants, through the storage of the dosage data of each land. The user did five scans, from each scan producing RGB values, each RGB value from five samples was then matched with the BWD dose color indicator. The sample dose results are then sent by the NodeMcu microcontroller to the webserver database. Based on the assessment of the test conducted by 10 Users by Gapoktan Farmers Group of Tosari Kendal Village, the total value of 372 that has been averaged to be 37.2 is between 31 - 40 which is classified in the category of "Very Valid or Very Effective".

The community's need for electricity is getting higher, so alternative energy sources such as solar heat are needed to replace energy sources from fossil fuels in meeting electricity needs. In this paper we design a two-axis solar tracker with an LDR sensor. A sun tracking system is a unit that is combined into one to control the position of the tracking device with the aim of making the surface of the solar panel module always facing the direction of sunlight. This research discusses the Prototype of the Sun Tracking System in Arduino Based Solar Power Generation Systems to get maximum solar energy. This system will make solar panels move automatically so that sunlight absorption can be maximized. The main control uses Arduino nano which gets input values ​​from the LDR sensor then is processed to the output system. With the control system method can automatically be seen the difference in the results of a fixed solar panel with a solar panel with a tracker, from the comparison we get a solar panel with a tracker to get more optimal results.

This paper outlines the Balala Tradition which is one of the Dayak Banyadu tribe traditions. The Catholic Church values the culture and values of the local wisdom of its people. However, inculturation of culture into a celebration of faith requires a method approach. Models of faith contextualization from Stevan Bevan are one of the methods used in this paper. Identification of the problem of the Belala Tradition is the weak signification of the faith of the Dayak Banyadu tribe who are Catholic in living the Belala Tradition. So the focus of this paper is on the inculturation of the Balala Tradition in the Catholic faith paradigm. The purpose of this study is to provide a theological basis and meaning of the Catholic faith for the value of locality in the Belala Tradition. This paper will explore the experience of the existence of the Dayak Banyadu tribe in living this tradition in the eyes of the Catholic faith.

Evangelism must become the lifestyle of all believers. Evangelism agrees to preach the good news about salvation in Jesus Christ and win people to Him, according to the Great Commission in Matthew 28:19-20. We have to be a witness of Jesus Christ and His Gospel as our lifestyle. Being a Christian is like being a witness for Jesus. Evangelism and witnessing are a major part of a believer's life with values that are in accordance with Christ's teachings. The Lord Jesus became a positive example of how evangelism became His lifestyle. In practice, the church develops a discipleship process to help, direct and produce the results of the gospel message and establish new believers in fellowship, holy baptized, discipleship, and practice. Being externally applied in two important parts namely go and make all the tribes become disciples of Christ. These two external parts will be accomplished by an effective compilation that has been disciplined as a disciple of Christ holistically. This external implementation guides and encourages each church to diligently preach the Gospel of Christ as a lifestyle in various life discussions.

Family becomes the smallest social unit in a society. The socialization process was first carried outin the family. Educate children to get to know children and how to treat children according to theirneeds and development. By recognizing and understanding their children, parents as educators inthe family will be able to increase their potential as optimally as possible, especially in formingpositive behaviors. Behavior is any form of action taken or planned. While positive behavior is anaction that is in accordance with the character, culture, norms and noble values in the community.In order for children to grow and develop optimally, the family or parents need to increase theirrole. Along with the times and the assimilation of culture in the era of globalization of positivebehavior in children such as manners, tolerance, caring for others and respect for others isincreasingly lost. The effort that can be taken to develop positive behavior of children in the familyenvironment is through a behavioral approach.The target of service is the Beneficiary Family(KPM) of the Hope Family Program in Wonosegoro District. The purpose of this communityservice activity is to provide training methods in enhancing family roles to foster positive behaviorthrough a behavioral approach. The method used in this community service is the behaviorismapproach in increasing family roles to form positive behavior. In this behavior approach usesseveral techniques, namely modeling techniques, reinforcement techniques and Asertive trainingtechniques. The implementation of community service carried out with seminars and trainingthrough lectures, discussions and brainstorming, questions and answers, and direct practice. Theimplementation of the behavioral approach training as an effort to improve the family's role informing positive behavior was Carried out in four meetings. The expected result of communityservice is the realization of parents' understanding of the importance of the role of the family infostering positive behaviors of children that are applied in daily life through a behavioral approach.Keywords: Family Role, Positive Behavior, Behavior Approach
