Abstract

Insufficient protein intake in children during the growth period is one of the causes of the increasing prevalence of stunting children in Indonesia. Fish has been researched to contain high levels of protein which is good for children's growth and development. In general, fish is only processed simply so it is not liked by children, whereas it can be processed into various processed products, such as nuggets. This community service aimed to determine the effect of providing fish nugget processing training on the knowledge of training participants. An increase in knowledge was measured using a one group pretest posttest design, which was then carried out with a real difference test to see the difference in the average pretest and posttest scores using the non-parametric Wilcoxon test. This training activity was given to 16 housewives and parents of Early Childhood Education School students in Situ Udik Village, Cibungbulang District, Bogor Regency with age characteristics ranging from 20-60 years and the latest education level was Elementary School-Senior High School. The results of this community service showed that providing training has a significant effect on increasing the knowledge of training participants in processing fish nuggets. The average pretest score of training participants (74.38%) showed a value that is significantly different from the average posttest score (95.63%) with significance value (Asymp. Sig.) 0.000. It is hoped that the results of this community service can be implemented by the community in producing fish-based nuggets for family consumption and sale to consumers.Keywords: Fish nuggets, food processing training, processed fish products, Situ Udik village, stunting.

Abstract

PT Perkebunan Nusantara VIII (PTPN VIII) is a State-Owned Enterprise (BUMN). It operates in the plantation sector.  The leading commodity is tea.  The demand for tea produced by PTPN VIII is increasing. Thus, planning tea production is necessary. One of the production planning efforts is through forecasting based on previous data.  Tea  production data is time-series data.  It contains seasonal elements and is dependent on other locations. We will analyze data with these criteria  using space-time models, one of which is vector autoregressive (VAR). VAR models the relationship  between observations on certain variables at one time. It also models the observation of the variable itself at previous times. Additionally, VAR models  the relationship  between observations and other variables at previous times. This paper explains how to forecast tea  production. It uses the reconstituted VAR and Seasonal Autoregressive Moving Average (SARIMA) models. The results showed that the reconstituted VAR model was better than the SARIMA model in predicting tea production. The tea production prediction was at the Sedep and Santosa plantations in Bandung Regency.

Abstract

One source of learning in the learning process is learning materials. In distance education, learning resources prepared for students must be able to be studied independently. The separation of lecturers and students needs to be bridged by learning materials that can be understood by students. A video is a form of learning materials that can be used to help students understand the material. Through videos, students can learn anywhere and anytime according to the time available. In the video, the duration of the material delivery is very significant. Likewise, components such as intro, greeting, and outro greatly support student motivation. The effective video duration in learning website-based statistical data analysis is 10-15 minutes. The component of presenting material that is in great demand by students in the discussion of sample questions and their application using R software.

Abstract

Abstrak: Transformasi digital telah mendorong perubahan besar dalam berbagai aspek kehidupan, salah satunya melalui kemunculan teknologi MBG yang memunculkan beragam opini publik. Penelitian ini menganalisis 6.728 komentar masyarakat di media sosial X (Twitter) menggunakan pendekatan text mining untuk menilai sentimen terhadap MBG serta membandingkan performa dua algoritma, yaitu Naïve Bayes dan Logistic Regression. Hasil awal menunjukkan akurasi masing-masing sebesar 90% dan 91%, namun ketidakseimbangan data dengan dominasi sentimen positif menurunkan nilai precision, recall, dan F1-Score. Melalui penerapan metode SMOTE untuk mengatasi ketimpangan data, performa kedua algoritma meningkat, dengan Logistic Regression menunjukkan hasil terbaik (akurasi 95%, precision 94%, recall 93%, dan F1-Score 95%). Temuan ini menunjukkan bahwa Logistic Regression lebih unggul dalam menganalisis sentimen masyarakat terhadap perkembangan teknologi MBG. Kata kunci: Naïve Bayes, Logistic Regression, MBG, Analisis Sentimen. Abstract: Digital transformation has driven significant changes in various aspects of life, one of which is through the emergence of MBG technology, which has generated diverse public opinions. This research analyzes 6,728 public comments on the social media platform X (Twitter) using a text mining approach to assess sentiment towards the MBG and to compare the performance of two algorithms: Naïve Bayes and Logistic Regression. Initial results showed respective accuracies of 90% and 91%, but data imbalance, with a dominance of positive sentiment, lowered the precision, recall, and F1-Score values. Through the application of the SMOTE method to address the data imbalance, the performance of both algorithms improved, with Logistic Regression showing the best results (95% accuracy, 94% precision, 93% recall, and 95% F1-Score). These findings indicate that Logistic Regression is superior in analyzing public sentiment towards the development of MBG technology. Keywords: Naïve Bayes, Logistic Regression, MBG, Sentiment Analysis.

Abstract

Lack of knowledge and information; limited resources; the stigma of complicated procedures and lengthy application processes; and expensive financing are factors causing most micro and small enterprise (MSE) products in Situ Udik Village to not have distribution permits for Home Industry Food Production Certificates (SPP-IRT) and halal certification. This condition causes these MSE products to struggle to compete in the market and is limited in reaching a wider market. This community service program aims to determine the effect of providing training and assistance in processing SPP-IRT distribution permits and halal certification on increasing the knowledge and legality of MSE partner businesses in Situ Udik. This community service activity is carried out through several stages, including socialisation, training and assistance, and monitoring and evaluation stages. This community service activity was attended by 15 MSE partners in Situ Udik Village, Cibungbulang District, Bogor Regency. The results of this community service show that the provision of training and mentoring has been proved to significantly increase the knowledge of MSE partners as evidenced by an increase in the average pretest score (74.5%) compared to the posttest score (82.5%), and there are as many as 13 Situ Udik MSE partners who successfully obtained SPP-IRT distribution permit certificates and halal certificates. With this community service, it is hoped that it can help Situ Udik MSE actors in improving product quality and safety, so that they have competitiveness in the market and a wider market reach

Abstract

Hydroponic cultivation has emerged as a strategic approach in community empowerment initiatives, particularly in contexts characterized by limited land availability, declining soil fertility, and constrained access to conventional agricultural practices. This study aimed to evaluate the effectiveness of a hydroponic training program in enhancing participants’ knowledge and readiness to adopt soilless cultivation techniques. A pretest and posttest design was employed to assess ten indicators encompassing fundamental hydroponic concepts, system typologies, nutrient management, and critical plant growth parameters. The findings revealed substantial improvements in participants’ knowledge, as evidenced by markedly higher post-test scores across all indicators. Significant gains were observed in participants’ understanding of suitable crop selection, optimal pH regulation, nutrient solution management, and the appropriate use of measurement instruments. Importantly, these enhanced competencies were translated into practical implementation, with participants, particularly members of the PKK group, successfully establishing hydroponic systems, conducting harvesting activities, and commercializing their produce through local bazaars. This outcome underscores the program’s tangible contribution to small-scale food production and the generation of supplementary household income. Taken together, the study demonstrates that structured and practice-oriented hydroponic training effectively strengthens technical capacity while fostering community empowerment and sustainable livelihood development
