Abstract

The manufacture of biodegradable plastics with the main ingredients of talas beneng (Xanthosoma Undipes K. Koch) starch, chitosan, and glycerol as a plasticizer has been carried out by various additions of starch and reduction of chitosan. Initial assessment of talas beneng starch reveals: starch content - 20.51%, water content - 8.58%, fat content - 12.71%, and protein content - 3.51%. Physical testing of biodegradable plastic produces thickness values ranging from 0.166 mm to 0.234 mm, tends to meet JIS Z-1707: 2019 standards, density value is 1.674 g/cm3, and the lowest water absorption value is 20.51%, both meet SNI 7188: 2016 standards, and there is a decrease in mass every week for 28 days in the biodegradation test.

Abstract

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 80°C and a firing temperature of 70°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.

Abstract

The purpose of this study was to evaluate students’ perceptions of Computer-Based National Assessment (ANBK) and how it impacts students’ literacy and numeracy skills. ANBK is one of the government’s efforts to evaluate students’ competencies using information technology. This study was conducted through direct observation and interviews with 30 students in grade V of elementary school. The results showed that the majority of students saw ANBK as an interesting tool and helped them learn. This study concluded that ANBK can help improve students’ basic skills in addition to improving their literacy and numeracy skills, although there were some problems with technology accessibility and students’ mental readiness. In the future, it is recommended to develop training programs and provide better technology facilities in schools to support better implementation of ANBK. Through this study, based on students’ perceptions of ANBK activities, it can be categorized as good or positive where students are able to find information, understand information, and evaluate and reflect in literacy activities, while in numeracy activities students can reason critically by using logic in solving problems in everyday life.

Abstract

This research aims to describe the image, position, and problems of Javanese female characters in the three novels of Naning Pranoto. This research is descriptive qualitative with a feminist analysis approach. The sources of data are the novels entitled Lupa Singgah di Shizi, Wajah Sebuah Vagina, and Mei Merah 1998 (Kala Arwah Berkisah) by Naning Pranoto. The research data are all lingual units in the form of sentences that contain the image, position, and problems of Javanese women in Naning Pranoto’s three novels. Data were collected using reading and note-taking techniques. Data analysis was conducted by comparing, categorizing, presenting, and making inferences. The results of this study show that the image of women displayed in the three novels by Naning Pranoto is quite dynamic because of the social contact experienced by the characters. Each character's background also affects the image labeled towards Javanese female characters in the three novels. When viewed from the position of female characters, Javanese women in the novels are depicted as figures who are more dominated by men. This could be Naning Pranoto's intention to protest or show cynicism towards those who marginalize women. Then the next problems shown in the novel mostly start from economic problems that cause other problems to arise such as sexual violence, oppression, and marginalization.

Abstract

The purpose of this study was to analyze the management of learning communities in improving teachers’ pedagogical competence, the challenges faced in conducting learning community programs, and analyzing solutions in overcoming the challenges of learning community programs at State Elementary School 229 Plaju Palembang City. One of the key factors in improving teachers’ pedagogical competence is teacher collaboration in learning communities with good planning, organization, implementation, and supervision. The research method used is a qualitative approach using data collection techniques such as observation, interviews, and documentation. Results show that 85% of teachers improved pedagogical skills through collaborative programs, though challenges like time constraints (reported by 70% of participants) persisted. The results show that learning community management has been implemented in a systematic and participatory manner, involving careful planning, data-based needs analysis, and implementation of relevant professional programs. This activity has the support of the principal and lead teachers, with a clear organizational structure and a strong culture of collaboration as reinforcing factors. The research also found various challenges in its implementation, such as limited time, human resources, member participation, and funding, which impacted the effectiveness and sustainability of the program. However, adaptive management strategies, the use of technology, the formation of interest-based work teams, and regular reflection overcame these challenges. The CERDIK learning community has proven to be an effective platform for teacher professional development and an example of good practice in the primary school environment.

Abstract

Mangrove ecosystems in Tanjung Rejo Village, Percut Sei Tuan Sub-district, Deli Serdang experienced a lot of land conversion in the form of residential, agricultural and plantation lands. This causes abrasion in this region because there is no protection from waves and sea waves in this region. Land conversion and abrasion caused many mangrove trees to die. Mangrove trees that died were only used on the trunk, twigs and leaves by local residents. Many parts of the dead mangrove roots are not utilized. This community service activity aims to provide information and skills to partner groups about the making of MAROCA. Through this activity, partners will gain knowledge and skills in making MAROCA so that materials that are not initially valuable like dead mangrove roots become useful. Based on the description of the problem and the purpose of this community service activity, the activities that have been carried out are counseling about the manufacturing of MAROCA, giving leaflets for the procedures for making and providing tools and materials. The results obtained are increased knowledge and skills of partners about the benefits of dead mangrove roots as economically valuable handicrafts.

Abstract

Society of Lingkungan VIII Kelurahan Gedung Johor, Medan City utilizes the Al-Buchari Mosque as a means of worshiping and gaining knowledge for the Muslim community. However, Al-Buchari Mosque still uses water containers to wash the hands of its worshipers in order to prevent the transmission of the Sars-Cov 2 virus, which is an increasingly worrying situation. Medan Johor District is a red zone area in terms of the spread of the Sars-Cov 2 Virus. Based on data from the Corona Pandemic Prevention Task Force, Medan City has had more than 1000 positive cases of Covid-19 in the city of Medan. This is due to the lack of public awareness of the importance of washing hands, maintaining distance, and wearing masks. One of the effective ways to prevent the transmission of the Sars Cov-2 virus is to create a sink that does not require us to hold it but control it with our feet. So that the spread of the virus through hand media can be avoided. With this non-contact hand washing, people who worship at the Al-Buchari Mosque will minimize the transmission of the Sars Cov-2 virus through hand media.
