This study aims to investigate the utilization of sorghum sap into bioethanol by fermentation process as well as to determine the maximum or optimum point of alcohol content produced by bioethanol. In this experiment, the independent variable used is the variation of fermentation time and the amount of yeast used in the fermentation process and the dependent variable is the alcohol content produced. This experiment was start by mixing the sap water with a mixture of yeast, urea, sugar and water in a certain amount and fermented for a certain time, then the results of the fermentation were distilled and measured the alcohol content. Experiments 1 and 2 show that the alcohol content continues to increase from the fermentation period of 36 hours, 48 hours, 60 hours, 72 hours, but at the fermentation time of 84 hours the alcohol content has decreased and when all the distillations are combined then distilled again, the alcohol content increases. In conclusion, the optimum point of alcohol is at the 72 hours fermentation time and the addition of the yeast dose only affects the amount of ethanol produced but does not change the level, the alcohol content produced cannot be made into bioethanol because the alcohol content is still low so it is necessary to carry out repeated distillation to achieve high alcohol content.

The purpose of this research is to provide solutions for renewable energy sources to replace fossil energy by conducting experiments using windmills. To prove that wind energy can be used as a renewable energy source, experiments were carried out on making windmills with different diameters and numbers of propellers and dynamos. The experimental results show that the windmill generates an electric current with one dynamo of 50A to 52.5A and cannot turn on the lamp yet, and with two dynamos of 150.5A to 153A and can light the lamp. In this experiment, an electric current was obtained which was sufficient to turn on the lamp in the use of two dynamos with a propeller diameter of 12 cm and the number of propellers, namely five. It can be concluded that the wind energy produced is influenced by the diameter, number of blades and also the number of dynamos used.

Tarogong Kaler, Kabupaten Garut, Jawa Barat 44151 *andinisa[at]uniga.ac.id Abstract Nowadays, high school students encounter high technology problems which they need 21st-century skills to give them the solution by learning STEM education that includes problem-solving, team working, creativity, innovation, critical thinking, and communication skills. On the other hand, STEM education in Indonesia is not as common as in the United States of America as a curriculum. Some teachers applied STEM education as a teaching method. Moreover, Indonesia has a National Curriculum which means that every school applies the same curriculum. This research aims to analyze how science teachers implement STEM education in their classes by using project-based learning and hands-on activities, and their knowledge and readiness to integrate STEM education into National Curriculum in Indonesia. The descriptive method is used for the research. The participants are collected by using purposive sampling which are 82 participants who are high school science teachers. This research uses a web-based questionnaire to collect the data which contained two parts, such as demographic and issue part with four and twelve questions, respectively. The researcher found that most of the participants (63%) have applied project-based learning and hands-on activities for a quarter of their course content. Moreover, they gave problems to students for more than half of the courses to improve students^ problem-solving skills. The research also shows that the participants used authentic assessments, such as portfolios to evaluate students^ performance. Based on the results, most of them have already known and implemented STEM education in some of their learning processes. Even though STEM education is already on the National Curriculum, in fact, that not every school knows and understands how to apply STEM in their classroom. Therefore, it is necessary to develop and improve the National Curriculum by integrating STEM education into the curriculum with all the stakeholder^s support.

The Fast and The Newton: Measuring Kinetic Friction through Composite Functions Dini Asri Kusnia Dewi, Hilman Panji Firdaus, Maulana Restanto SMA Darul Hikam Internasional Abstract Friction is prevalent in our everyday life. Friction emerges as two surfaces of bodies are in physical contact. There are two types of friction that may occur depending on the state of an object, static friction and kinetic friction. Most of these concepts are learned theoretically in class. Apart from relating to the basic arithmetic operations, this concept also deals with the theory of composite functions. This study aims to invite students to apply concepts in project activities so that students can get an idea of how these concepts are related in their daily life. This study was conducted through a project developed jointly by physics, mathematics, and English teachers. The project is divided into several activities that will be carried out by students such as making toy cars to video presentations. The results showed that students were able to interpret the relationship between the concepts they learned from various subjects into a fully integrated meaning.

Urgent Need for Land Subsidence Hazard Education in Indonesia to Increase Community^s Awareness and Preparedness Dwi Sarah (1)*, Eko Soebowo (1), Nugroho Aji Satriyo (1), Taufiq Wirabuana (2), Risna Widyaningrum (2) 1) Pusat Penelitian Geoteknologi, Lembaga Ilmu Pengetahuan Indonesia, Jl. Sangkuriang Gedung 70, Bandung 40135, Indonesia 2) Pusat Air Tanah dan Geologi Tata Lingkungan, Badan Geologi, Kementrian Energi dan Sumberdaya Mineral, Jl. Diponegoro No.57, Bandung 40122, Indonesia Abstract Natural hazards and disaster education are significant for building community resilience and preparedness necessary for mitigation and reconstruction measures. Natural hazard education in Indonesia has covered the topics of seismic-induced, volcanic, and hydro-meteorological disasters extensively. However, there has been little to no mention of land subsidence yet. Land subsidence is the lowering of the ground surface due to the downward movement of the earth^s surface. The process of land subsidence is so subtle that many do not realize that subsidence takes place until the impacts are widely visible and felt. Exposure to land subsidence is very high, where subsidence has occurred in 134 districts across 21 provinces in Indonesia, particularly in the coastal regions in North Java and East Sumatra. There is an urgent need for public education to build the community^s capacity for effective mitigation. This paper aims to provide state-of-the-art knowledge on land subsidence hazard in Indonesia and propose a framework for land subsidence education. Land subsidence in Indonesia is potentially driven by its natural condition and rapidly accelerated by anthropogenic interventions. The structure for land subsidence learning material should cover formal and non-formal education and provide separate modules for each stage. Collaborations between researchers and educators are needed to ensure successful formulation and implementation of land subsidence education.
