Community empowerment that was raised was to provide counseling about the importance of an education in Karo District, Brand District of Tongging Village. Education is a learning, knowledge, and skills acquired in both formal and non-formal schools. Education is very important for every human being because it can create quality human beings, intellectual, and far from ignorance. The state has regulated the right of every Indonesian citizen to get education as a means to improve his quality of life, namely the Article 28 C of paragraph 1 and 2 and article 31 paragraph 1 and 2. With a pulakita education, we can build the nation to be more advanced. In Tongging village, there are 3 schools namely Pelita PAUD, 044854 Public Elementary School and Karya Tongging Private Middle School. The number of students is also still low, namely 36 PAUD students, 162 SD students and 45 SMP students. The problem at this school is the lack of facilities in schools such as inadequate bathrooms and the lack of electricity. But despite the inadequate facilities of children and adolescents in Tongging have never been affected by juvenile delinquency which has an impact on social irregularities.

The research is aimed to investigate the possibility of acrylic-reinforced glass fibre as a denture. Short glass fibre was made by variation of 4mm, 6 mm and 8mm. The results showed a good adhesion between glass fibre and acrylic resin with an optimum composition of the denture (acrylic: oil : glass fibre = 10 gr : 4.5 mL : 0.13 gr) was achieved. The density test was conducted by using Archimedes’ method, whereas compressive strength and tensile strength by using Universal Testing Machine (UTM). The results showed that glass fibre can be used to enhance the mechanical properties of acrylic resin. The optimum composition was achieved when 6 mm fibre had been added-in with a density of 1.2256 gr/cm3. A compressive strength of 76.623 MPa and a tensile strength of 71.207 MPa were recorded, these values can be applied as a denture.

Bioplastics are plastics that can be used like conventional plastics but can be more easily decomposed in the soil. Studies have been conducted to determine the effect of temperature variations in the gelatinization of porang starch on the manufacture of bioplastics with sorbitol plasticizers on their characterization. In this study, bioplastics have been produced which are made with variations in the composition of starch: chitosan (30:70) %, (40:60) %, (50:50) %, (60:40) %, and (70:30) % with the addition of sorbitol as a plasticizer and heating process at gelatinizing temperature variations of 70 Â° C, 80 Â° C, and 90 Â° C. The results showed that the variation in gelatinization temperature affects the thickness, density, and absorbency of bioplastic water. Where the higher the temperature of gelatinization, the thickness of the bioplastics will decrease, the density of bioplastics will increase, and the absorption of bioplastic water decreases.

Edible films present an eco-friendly alternative for food packaging compared to traditional plastic materials. This study investigates the effects of glycerol and sorbitol plasticizers on the properties of edible films. The research involves crafting these films using porang (Amorphophallus Oncophyllus) starch. Glycerol plasticizers were incorporated at a concentration of 100%, while sorbitol was utilized at varying levels (0%, 25%, 50%, 75%, 100%) to evaluate their impact on film characteristics. The films were produced using the melt intercalation method at a gelatinization temperature of 80Â°C and a firing temperature of 70Â°C. Notably, the most favorable physical test outcomes were observed with adding 100% sorbitol, including thickness, density, water absorption, and degradability improvements. Meanwhile, adding 25% sorbitol yielded the highest tensile strength and elongation values.
