Abstract

Gelam (Melaleuca cajuputi) dominantly found on tidal swamp areas of Central Kalimantan. The study was conducted to investigate the quality of charcoal from stem section based on the grow place, the location of A (flooded of the big tidal, peat thickness is 51-100 cm), location B (unflooded of the big tidal, peat thickness is 101-200 cm), and the stages of tree growth (saplings, poles, and trees). The parameters observed were yield, moisture content, volatile matter content, ash content, carbon content in bound, and calorific value. Charcoal from gelam generally meets the requirement of SNI 01-1683-1989, SNI 06-4369-1996, and Malaysia standards. The average value of the charcoal yield is 28.090-28.545%, the charcoal water content is 4.605-5.413%, the volatile matter content of charcoal is 30.286-34.635%, the ash content of charcoal is 1.840-2.386%, the bonded carbon content of charcoal is 58.37-62.46%, and the charcoal calorific value is 6937.43-7530.09 cal g-1.Key words: biomass energy, calorific value, charcoal, Melaleuca cajuputi

Abstract

The purpose of making this paper is to find out the meaning of Technology-Based Education the benefits of technology in the world of Education, as well as knowing the obstacles to the application of technology-based education. Technology is one of the keys to making education more prosperous. With technology-based education greatly influences the development of education both in the learning process and in the preparation of the curriculum, especially in building adequate educational facilities and infrastructure so that educational goals can be implemented. students to learn and get the information we need from anywhere, anytime, and from anyone. Constraints on the use of technology in schools include limited budgets for limited human resource learning facilities, hard work and lack of teacher competencies. Some benefits of the application of puzzleology in education, technology can help teachers teach, technology will trigger teacher creativity, help students learn, puzzleology can create learning activities that attract students easy to find learning resources, technology can improve school standards, make students have a broad insight

Abstract

The research problem is that students are mildly mentally retarded and have poor understanding of the material for calculating multilevel additions. The aim of this research is to improve understanding of compound addition material by storing techniques through the use of number value racks. Class IV students at the Toboali State Special School who have mild intellectual disabilities will benefit from a better understanding of the concept of multiple addition operations. This type of research is called Classroom Action Research (CAR). This research was carried out in two cycles, each cycle being carried out in three meetings. Each cycle has four interrelated phases: observation, reflection, action implementation, planning phase, and reflection. The research subjects were four fourth grade Toboali State Special School students with mild intellectual disabilities. Data was collected through test and observation methods. Quantitative analysis was carried out on the data, and a table was presented showing student learning outcomes. Based on the results of research carried out in cycle I and cycle II, it shows that the use of number value racks can improve students' understanding of the material of addition in layers using storing techniques.
