However, when compared to countries in the ASEAN region, the prevalence of stunting in Indonesia is still higher than Vietnam (23%), Malaysia (17%), Thailand (16%) and Singapore (4%), only better than Myanmar (35%). Currently, Indonesia is experiencing what is called the triple burden of malnutrition. The triple burden of malnutrition is not just a matter of malnutrition, but also excess, and imbalance in nutritional intake. For this reason, snacks are made in the form of healthy flakes which can be used as an alternative to overcome the stunting problem in Indonesia. The purpose of this research is to produce healthy flake products rich in nutrients for stunting sufferers. The experimental design in this study consisted of two factors. The first factor was the proportion of corn flour: cowpea flour (50:50 ; 60:40 ; 70:30) and the second factor was the addition of 4% sunflower seed oil respectively. The result showed that the flake aproximately has 2,46-2,88% moisture content, 1,46-1,76% ash content, 3,76-5,91% fat content, 6,87-7,24% protein content, and 81,4-84,85% carbohydrate content.

Presently, there is a rapid and significant advancement in battery technology. Consequently, there is a concurrent rise in the demand for energy to fulfil every day, industrial, and transportation requirements. A promising avenue for diminishing reliance on non-renewable energy sources is the innovative conversion of waste materials into alternative energy reservoirs. In this context, the conversion of discarded coconut shells into activated carbon emerges as a valuable strategy for fabricating battery anodes. Several constituents, including activated carbon, LiOH, TiO2, and adhesives, can be employed in the production of battery anodes. The amalgamation of activated carbon with LiOH yields an electrical conductivity of 2.064 x 10-3 Sm-1, along with a specific capacitance of 4.46154 F/g for activated carbon derived from coconut shells. Alternatively, other carbon composites exhibit superior electrical conductivity, registering a value of 15.31 x 10-2 Sm-1, accompanied by a specific capacitance of 140.2 F/g. This comprehensive literature review aims to serve as a pivotal resource for selecting optimal raw materials in the synthesis of battery anodes. The result of this review substantiates that activated carbon sourced from coconut shells is one of favourable materials for crafting battery anodes.

Authors: Parsaoran Tamba  , Hendro M. Sumual
Published: October 2023

Vocational High Schools (SMK) are educational institutions that prepare graduates to be ready to work, so that there are more practical lesson hours compared to theory lesson hours. With so many hours of practice, vocational school students are very vulnerable to work accidents. Preventive measures against work accidents, when students carry out work practices, must implement K3. The behavior of implementing K3 can be influenced by the K3 hard skills mastered by students, the soft skills possessed by students and the practical work environment. Through this research, we want to find out how much influence K3 hard skills, soft skills, and work environment have on students' behavior in implementing K3. The student population as respondents was 73 students taken from vocational schools that have a mechanical engineering study program, namely SMKN 2 Bitung, SMKN 2 Manado, SMK Garuda Bitung and SMK Cokroaminoto Kotamobagu. By using a saturated sampling technique, the entire population was taken as a sample with a sample size of 73 students. The analysis technique in this research uses regression and correlation analysis techniques, and it is revealed that there is an influence between hard skills on the behavior of implementing K3 of 0.69 (69%), there is an influence between soft skills on the behavior of implementing K3 of 0.76 and there is an influence The relationship between work environment and behavior of implementing K3 is 0.85 (85%). With these findings, it is hoped that vocational schools will focus more on improving occupational safety and health (K3) learning materials so that students have optimal K3 hard skills. Providing lessons or other activities that can develop students' soft skills and improve the comfort of the welding work practice environment must be taken into account, such as noise levels, ventilation, lighting, room cleanliness and preparing complete personal protective equipment (PPE).

Published: October 2023

Information overload on e-commerce sites or applications makes users spend more resources than they should. Buyers should be able to use it according to their own habits, needs, wants and beliefs. Personalization of e-commerce is a solution that can be used to overcome this problem. In this paper, the researcher creates a framework for personalizing e-commerce, especially for small and medium enterprises. This framework consists of the customer behavior assumption, technology requirement and business assumption. The customer behavior assumption contains an approach to the habits/nature of the buyers themselves. By understanding this, e-commerce can offer something suitable and different for each person. Meanwhile, with technology requirements, e-commerce is able to adapt to the development of content and scalability of e-commerce itself. To make users feel comfortable and willing to go back to shopping at the same e-commerce, the business assumption is another component in this framework. We conclude that the use of this personalization framework can have a major impact on increasing user retention in e-commerce.

Published: October 2023

Technological developments cannot be denied a very meaningful impact on human life so that what was previously done traditionally is now completely digital, for example conventional news media which has been transformed into an online news portal so that it can still reach its readers. Online news portals provide a lot of up-to-date information, including tourism news, which is an industry that continues to grow and has the opportunity to create new jobs for the community. Currently, to search for tourism news, people only need to type a keyword (query) in the search engine which will then display the latest news about tourism. However, not all tourism news displayed matches what they are looking for, so readers have to re-check which takes a lot of time. Therefore, a tourism news retrieval system that can display the most relevant tourism news to the query is proposed. The Modified Cosine method shows good results in document clustering to bring the inter-cluster distance closer. This study uses the Modified Cosine method and TF-IDF weighting schema to determine the value of precision, recall, and f-measure in calculating the similarity of the query to tourism news documents. The system has been tested using 3 types of queries, with 5 different words each. The test results show that Modified Cosine method obtained best precision value in the test using 5 words in the query and the F-Measure value and the best recall on the 3 words test in query.
