Material structure and function of plant tissue is one of the most difficult material for students to understand. This is because studying this material in detail requires aids (microscopes) whose observations are not necessarily easily understood by students. In addition, so far the learning media and methods used are less varied. Based on the above statement, we need a learning media that can increase student interest and student understanding in learning the structure and function of plant tissue. So this study aims to develop a monopolistic educational learning media on the structure and function of plant tissue in class VIII of SMPN. This development research refers to the ADDIE model (Analyze, Design, Development, Implement, Evaluation). The monopoly game structure and plant network developed consists of several game equipment including: a monopoly board, a set of ownership rights cards, a set of public and opportunity fund cards, a set of money - dice, and a game guide. As for the pawns in this game are the students themselves. Based on the material expert validation test, it was found that the percentage of material suitability in the monopoly of the structure and function of plant tissue was 70.83% or quite decent. Meanwhile, for the media expert validation test the percentage of eligibility was 63.33% or quite decent. Based on the validation test obtained an average of 67.08% or if interpreted then the monopoly of the plant's structure and tissue is quite feasible.

Learning physics science is ideally accomplished through the experiments, although the theory of special relativity is challenging to understand. It is difficult because this topic has not occurred in real experience, and no technology has launched at the speed of light. To understand this theory, Virtual Reality (VR) can potentially visualize the actual concept of relativity by presenting an artificial environment to the students. The aim of this research is to develop the virtual reality application as a learning media for special relativity. This Research and Development uses the Lee and Owens Model, which consists of analysis, design, development, implementation, and evaluation. The system development method used is black-box testing. The result of the development of this system is the creation of a VR application to explain the material of relativity. From the results of black-box testing, the test results show that the percentage of application system success is 83%, which indicates that the application is functioning correctly on smartphone usage so that this application can be used on the theory of relativity simulation users using virtual reality devices.

Global warming that cause climate change effects has become the center of attention around the world to find a solution in order to reduce or minimize its impact. Formerly, Indonesia was an agricultural country. Currently, Indonesia has started become a state-based industries, especially in DKI Jakarta. The impact was increasing CO2 emissions since the Industrial Revolution. The primary causes are deforestation and the burning of fossil fuels such as coal. CO2 levels have risen, so have its effects on air pollution. In addition, Indonesia has one of the marine resource can be used to absorb CO2 is faster than land plants that is Nannochloropsis sp microalgae. Therefore, the Nannochloropsis sp microalgae photobioreactor as eco-green technology will be placed on the rooftop of high buildings. So, it is expected as a potential solution in order to realize a healthy Indonesia 2030. Microalgae photobioreactor was created to find out how much CO2 absorbed and O2 produced. This research was conducted among 4 months in State University of Jakarta. The steps were study literature, supply tools and materials, photobioreactor manufacture, due diligence, Nannochloropsis sp cultivation, and CO2 absorption and O2 production test. The data obtained between CO2 absorption and O2 productivity is directly proportional. In the first, second and third repetitions CO2 absorption and O2 production were found at 40%, 68% and 83%. Therefore, microalgae photobioreactor can be one solution to reduce CO2 emissions, especially city-based industries in Indonesia. So, microalgae photobioreactor assisted by solar energy as eco-green technology can be applied to reduce CO2 emission trigger global warming that causes climate change effects in city-based industries.

Rolade is a dish cooked in the form of a roll, typically made from a flat piece of meat that has high animal protein. However, in Indonesia, the consumption of animal protein is still low. The needs of rolade ingredients, which is meat, can not be used by middle to lower society. Due to its high price, we substitute the usage of meat in rolade with cheaper ingredients but the protein content not inferior to the meat, namely tempe. To make more nutritious, we added tempe rolade with sweet corn (Zea Mays Saccharata). This study aims to test the effect of sweet corn addition on tempe rolade with organoleptics test which include color, taste, aroma, texture and level of public acceptance. Furthermore, this study aims to provide innovative use of plant-based protein to foods. The method used is experiment by varying the addition of sweet corn, i.e., 15%, 30%, and 45%. Based on the results of the organoleptic test by 2 people nutritionists and 1 culinary expert showed that the A5 treatment (55:45) with sweet corn addition as much as 45% produced the color (gold), the taste (savory and sweeter), the aroma (savory) and the best texture (soft and solid). While the acceptability test results shows that the highest favorite value by hedonic scale is 3.95. Therefore, based on organoleptic results, the best composition of sweet corn added 45%. Therefore, tempe rolade with sweet corn addition in favor of affordable nutrients and overcome low nutrients to support Indonesia Emas 2030. &nbsp
