Abstract

The drying process is often a problem in maintaining the stability of probiotics and the quality of microcapsules in the processing of synbiotic microencapsulation. This study aims to optimize the temperature and drying time to maintain the core material's stability and the microcapsules' quality. The research design in this study was a completely randomized design with two factorials, namely drying temperature (30°C, 35°C, and 40°C) and drying time (2, 2.5, and 3 hours). The results showed that the highest viability and efficiency values ​​were obtained in the drying process at 40°C for 2 hours, which were 9.29 log CFU/mL and 98.10%. In addition, the water content and gel strength of the microcapsules obtained also showed optimal conditions. Based on the results obtained, it can be concluded that the drying process at 40°C for 2 hours is the best treatment, with the highest viability and EE values ​​and low water content values.

Abstract

PT Z operates in the production of clean water, which has the potential to generate noise due to machinery used in the processing process or clean water dosing system. Noise that occurs in the production area can affect the health and comfort of operators and visitors who are in the location. This study aims to identify noise levels, recommended exposure duration, areas exposed to noise, as well as analyze the causes of noise and provide proposals for its control. The noise measurement method used refers to the noise mapping method and uses a sound level meter. The data obtained was then processed into contour maps with purple, green, yellow, orange, and red color variations using Surfer 16 software. The results showed that the highest noise level reached 86.5 dB, while the lowest was 56.7 dB. Based on calculations using the NIOSH formula from 40 measurement points in the noise mapping method, there are 7 points that require increased noise control. The highest noise level was recorded at 86.5 dB with an exposure duration of 5.65 hours (393 minutes). Noise control efforts can involve three elements, noise sources, noise dispersal paths, and noise receivers, which are matched with the control hierarchy referenced from the Permenaker No. 5/2018.

Abstract

The role of government and related institutions in farmers' social capital through networks, norms, and trust, can affect farmers. One form of influence is to increase the empowerment of farming communities through empowerment programs carried out by extension to farmers. The purpose of this research is to formulate a model of strengthening social capital in empowering farmers in farmer groups. This research was designed descriptively using interview and survey methods. The sampling method is purposive sampling (Purposive Sampling Method). The research respondents were farmers in Tara-tara Village and Kayawu Village with a total of 100 respondents. Data collection methods were carried out by interviewing and surveying respondents. Primary data were obtained from respondent farmers through direct interviews, secondary data were obtained from various related agencies. The research data obtained were analyzed through three processes, namely reducing data, presenting data, and verifying data. Data verification was done by triangulating primary data sources, namely in-depth interviews, observation, and documentation with secondary data. Data reduction was done by writing a summary of interviews with respondents while in the field. Meanwhile, data presentation was done by tabulation to classify the data. Data verification is done by drawing conclusions. The results show that social capital involves three main aspects. These include trust, norms, and networks.  Each aspect is assessed based on the indicators that make it up which are then used to measure the average strength of social capital of farmers in Tomohon City

Abstract

This study explores the issue of students' low Higher Order Thinking Skills (HOTS) in Science, specifically on the topic of Acids, Bases, and Salts, in Class VII-5 at UPT SPF SMPN 40 Makassar. The research aims to evaluate how effective the Problem-Based Learning (PBL) model, supported by interactive media, is in improving students’ HOTS. It also examines the level of improvement in each learning cycle and assesses the observed HOTS development throughout the study. Additionally, the research seeks to determine whether there is a significant increase in students' HOTS after applying the PBL model with interactive media. This study follows the Classroom Action Research (CAR) methodology, conducted in two cycles that include planning, implementation, observation, and reflection. Data was collected through HOTS test results (quantitative data) and classroom observations (qualitative data). In the pre-cycle stage, none of the students passed the test, with all 30 students falling below the learning criteria. In Cycle I, 18 students passed, while 12 did not, leading to a class-wide learning completion rate of 60%, categorized as low. Classroom observations during this cycle showed a score of 59.58%, considered fair. In Cycle II, all students successfully passed, increasing the success rate to 83.33%, classified as high. Observations also improved, reaching 66.67%, categorized as good. These findings suggest that the use of Problem-Based Learning with interactive media can effectively enhance students' HOTS.

Abstract

Adolescence is a time when someone wants to try various things. HIV/AIDS status is very vulnerable in adolescence, especially sexual deviations. However, when teenagers contract HIV/AIDS, they face many obstacles. The type of research used was qualitative with in-depth interviews with a purposive sampling method, namely snowball sampling of six informants. Six themes were found, namely transmission of HIV/AIDS through free sex, physical impacts where teenagers can still carry out daily activities independently even though they have symptoms such as fever, mouth ulcers, dermatitis, STIs, weight loss and activity You can still do it independently on a daily basis, the psychological impact that changes occur, such as sad crying, fear, rejection, depression, trying to commit suicide, worrying, being alone, and trying to end your life, the existence of social support. Community perception of HIV/ AIDS includes fear, shame, sadness, isolating oneself, depression and trying to end one's life, prevention efforts are made by adolescents to prevent HIV/AIDS by not having free sex, using condoms when having sex, and carrying out HIV/AIDS tests, and spiritual impact by carrying out activities such as praying and reading holy books.

Abstract

This study investigates the potential synergy between metaphorical thinking profiles and Higher-Order Thinking skills (HOTs) optimization in contemporary education. The research employs a qualitative methodology, utilizing literature review and content analysis to construct a comprehensive epistemological framework. The study's primary objective is to elucidate the relationship between symbolic thinking processes and the development of HOTs, specifically focusing on the dimensions of analysis, evaluation, and creation. The resultant conceptual framework demonstrates a strong correspondence between the stages of metaphorical thinking (including target concept identification, source domain exploration, structural mapping, elaboration, extension, evaluation, adjustment, and integration) and the core components of HOTs. These findings suggest that integrating symbolic thinking processes into educational strategies could significantly enhance HOTs development, potentially revolutionizing pedagogical approaches for the 21st century. This research contributes to the growing body of literature on cognitive skill development and offers practical implications for educators seeking innovative methods to prepare learners for the complexities of the global era.

Abstract

This article analyzes the satisfaction of website-based virtual tour users using the usability scale system method for tourism experiences in Chinatown Semarang for respondents who use the virtual tour application both in the initial and final applications. This research aims to compare user satisfaction by analyzing the score calculation results from 80 respondents from each virtual tour application using the system usability scale method where the virtual tour in the initial application and the virtual tour in the final application have differences in the addition of a simple interactive website and a guide in the form of a manual book and video tutorial in the final application. The system usability scale d calculation score was obtained with an increase in value of 7.875. This proves that modifying the application and adding a guide feature in the form of a manual book and video tutorial can help respondents use a virtual tour in Semarang's Chinatown village. The advice obtained in this research is that it is hoped that for future research, you can use paid hosting because, in the study here, the virtual tour application still uses free hosting, which still has limitations in processing files, so it takes longer for users to access the virtual tour in Semarang Chinatown Village.
