Abstract

Sign language is a harmonious combination of hand gestures, postures, and facial expressions. One of the most used and also the most researched Sign Language is American Sign Language (ASL) because it is easier to implement and also more common to apply on a daily basic. More and more research related to American Sign Language aims to make it easier for the speech impaired to communicate with other normal people. Now, American Sign Language research is starting to refer to the vision of computers so that everyone in the world can easily understand American Sign Language through machine learning. Technology continues to develop sign language translation, especially American Sign Language using the Convolutional Neural Network. This study uses the Densenet201 and DenseNet201 PyTorch architectures to translate American Sign Language, then display the translation into written form on a monitor screen. There are 4 comparisons of data splits, namely 90:10, 80:20, 70:30, and 60:30. The results showed the best results on DenseNet201 PyTorch in the train-test dataset comparison of 70:30 with an accuracy of 0.99732, precision of 0.99737, recall (sensitivity) of 0.99732, specificity of 0.99990, F1-score of 0.99731, and error of 0.00268. The results of the translation of American Sign Language into written form were successfully carried out by performance evaluation using ROUGE-1 and ROUGE-L resulting in a precision of 0.14286, Recall (sensitivity) 0.14286, and F1-score.

Abstract

In poultry farming, particularly for Day-Old Chicks (DOC), maintaining an ideal environmental condition is a significant challenge due to the limited ability of mother hens to provide adequate warmth and care. This often leads to a high mortality rate among DOC, especially in broiler chickens. The research contribution is the development of an intelligent incubator system based on fuzzy logic to automate environmental control and reduce DOC mortality rates. The system employs a DHT22 sensor to measure temperature and humidity, and an MQ-135 sensor to detect ammonia levels. An ESP32 microcontroller is used for data processing, chosen for its built-in Wi-Fi capability and high processing power. The DHT22 sensor controls a fan and UVA+UVB lamp via an AC dimmer, while the MQ-135 sensor controls a DC motor through the L298N driver. The fuzzy logic method is applied to make more accurate control decisions, and the entire system is connected to an IoT-based monitoring platform that provides a real-time dashboard for farmers. Preliminary results show that the system successfully maintains temperature within the optimal range (30–34?) and humidity (40–70%), and responds efficiently to changes in ammonia concentration. Compared to conventional systems, this intelligent incubator offers better automation, lower energy consumption, and cost efficiency. In conclusion, the proposed system provides a scalable and efficient solution for DOC management. Future work includes AI-based prediction integration, mobile application development, and historical data analysis for smarter poultry farm management.

Abstract

Notaries have an important task in providing legal services to the public, particularly regarding the making of authentic deeds. The determination of minimum service rates for notaries by the Indonesian Notary Association (INI) is regulated in the Notary Code of Ethics with the aim of preventing unfair competition and protecting the rights of notaries. This research aims to analyze the form of the agreement on the determination of minimum service rates for notaries, evaluate the role of INI in determining these rates, and examine the legal consequences of violations of the minimum rate determination. This is a qualitative research with a single case study approach in Hulu Sungai Selatan Regency, South Kalimantan. Data was collected through in-depth interviews with notaries, clients, and other related parties, observations at notary offices, and studies of relevant documents. The determination of minimum rates by INI is carried out through a mechanism of study and evaluation by the INI Regional Administrators which is submitted to the INI Central Administrators to be determined nationally. This determination is a form of agreement that binds all INI members. Violations can be subject to sanctions from the INI organization as well as administrative sanctions from the Notary Supervisory Board. Obstacles in implementing the minimum rates include differences in operational costs between regions, resistance from notaries, weak monitoring and law enforcement, and a lack of flexibility in facing changing economic conditions. Efforts that can be made include determining varying rates, socialization and education, forming a supervisory body, a mechanism for rate adjustments, and maintaining a balance with consumer protection.

Abstract

Background: Adolescents aged 10–19 experience rapid development, making them vulnerable to nutrition and mental health issues; to address this, the RAN PIJAR program was implemented in Bogor using the Meaningful Youth Participation (MYP) approach through Health Heroes Facilitators to enhance their health knowledge. Methods: This quasi-experimental study used a one-group pre-test and post-test design involving 335 adolescents aged 15–18 years from nine senior high schools and one city-level scout organization in Bogor City. Health education sessions applied participatory methods such as Focus Group Discussions (FGDs), Human-Centered Design (HCD), and audiovisual materials. Wilcoxon signed-rank test was used due to non-normal data distribution. Results: After the intervention, the proportion of respondents with good knowledge on mental health and nutrition increased significantly from 50.1% with poor knowledge to 80.9% with good knowledge. A statistically significant improvement was observed (p = 0.000), with median rising from 50 (pre-test) to 90 (post-test). Conclusions: The intervention using the MYP approach effectively improved adolescent knowledge on mental health and balanced nutrition. The participatory and peer-led design created a relatable and engaging environment for adolescents. Future health education programs should adopt a sustainable, gender-equitable, and media-diverse approach and be integrated with school-based health initiatives such as School Health Units (UKS) and healthy canteens.
