Get PDFMonitoring temperature and air quality are important factors in creating a comfortable and safe treatment room environment for patients. This study aims to design and implement an Internet of Things (IoT)-based temperature and air quality monitoring system integrated with automatic blower control. The system was developed using the Research and Development (R&D) method by utilizing a DHT22 sensor for temperature and humidity measurement and an MQ135 sensor for air quality detection, controlled by NodeMCU ESP8266. The system was tested by comparing the temperature sensor readings with a thermohygrometer and testing the system's response to changes in environmental conditions. The test results showed that the system was able to monitor temperature and air quality in real-time with a temperature measurement error rate of 0.21% and was able to activate the blower automatically when the temperature and air quality values exceeded the specified thresholds. Thus, the developed system proved to work well and can be used as an IoT-based environmental monitoring solution for treatment rooms
Sistem Prediksi Kualitas Air Konsumsi Machine Learning Menggunakan Algoritma Random Forest
Get PDFThis study aims to design and implement a clean water quality prediction system based on machine learning using the Random Forest algorithm. The background of this research is the limited public access to fast information regarding water feasibility, while laboratory testing requires significant time and cost. The data used is synthetic data constructed based on the value ranges and threshold limits of water quality in SNI 3553:2015, SNI 3553:2023, and the Ministry of Health Regulation No. 2 of 2023, so that it remains representative and aligned with real conditions. This dataset was created because field data is difficult to obtain completely and in a standardized form, but it still imitates real condition variations according to national standards, with feasibility labels determined based on official regulations. The system development uses the Agile method through the stages of dataset creation, preprocessing, training, evaluation, and application implementation. The Random Forest model is used to classify water into suitable, moderately suitable, and unsuitable categories. The test results show that the model with three physical parameters achieved an accuracy of 96.67%, while the model with ten chemical parameters achieved an accuracy of 100%, confirming that adding more parameters can improve prediction accuracy. This system is expected to help the public and environmental officers in conducting an initial assessment of water quality quickly before laboratory testing and can still be further developed to become more applicable in various regions
Optimasi Mobilenetv2 Dengan Transfer Learning Untuk Klasifikasi Penyakit Daun Cabai
Get PDFThis research effort seeks to establish a robust classification model for chili leaf diseases through optimization of the MobileNetV2 architecture using transfer learning methodology. The presence of diseases in chili plants is often a major barrier to agricultural productivity, necessitating the development of a rapid and accurate early detection system. The dataset used for this investigation includes six different leaf condition categories, specifically: Bacterial Spot, Cercospora Leaf Spot, Leaf Curl Virus, Healthy Leaf, Nutrient Deficiency, and White Spot. The investigation process begins with an image pre-processing phase and the application of data augmentation techniques, which aim to increase the variability of the training data while simultaneously reducing the risk of overfitting. Next, the model is trained using pre-trained weights from ImageNet, which are adjusted to align with the inherent visual characteristics of chili leaves. Model evaluation is conducted rigorously based on accuracy, precision, recall, and F1-score metrics. The experimental results demonstrate outstanding performance, with the model achieving an accuracy rate of 99%, an average F1-score of 0.99, and a validation loss of 0.07. These figures demonstrate the model's highly competent generalization ability when applied to new data. Analysis facilitated by a confusion matrix found a very low error rate, with only 11 images (0.73%) misclassified out of a total of 1,500 test images. These results support the assertion that MobileNetV2 optimization is highly efficient and accurate in identifying chili leaf diseases. This model has significant potential for integration into mobile devices or digital image-based smart farming systems, thereby assisting farmers in making informed decisions in real time
Multicultural Education Based on Local Tradition of Selametan in History Learning Practice
No full textRadicalism remains a threat in Indonesia, where extreme views are rooted in a misguided understanding of diversity. History lessons at State Senior High School 9 in Yogyakarta adopt a multicultural education approach to promote understanding of diversity by introducing local Javanese traditions, such as selametan, through an inclusive model. This study explores how history education at State Senior High School 9 in Yogyakarta integrates the material taught with multicultural values to promote tolerance and inclusiveness. This study uses a qualitative case study method at SMA Negeri 9 Yogyakarta, with data collection techniques including observation, in-depth interviews, and document analysis. The sampling technique used is purposive sampling, involving several subjects, including the Deputy Principal for Curriculum, Deputy Principal for Facilities and Infrastructure, history teachers, and representatives of 10th grade students at SMA Negeri 9 Yogyakarta. Data validity and reliability were obtained through data triangulation techniques and analyzed using an interactive model. The research findings show that integrating history material with the local Javanese tradition of selametan is an effective way to foster tolerance and cooperation among students from diverse backgrounds. This strategy involves a collaborative Project-Based Learning (PjBL) model, demonstration methods, and class discussions to provide an understanding of diverse perspectives and encourage students to get used to living side by side. In this context, a school culture that accommodates student diversity also plays a crucial role in creating an inclusive and fair learning environment
The Socio-Economic Dislocation of the Javanese Chinese Community during the Revolution: The Transformation from Citizens to Refugees
No full textThe journey towards Indonesian independence not only fostered a spirit of nationalism but also revealed a dark side in the form of social suffering among the people. One of the forgotten tragedies was the displacement of ethnic Chinese communities in Java, who lost their homes, jobs, and sense of security amid the political turmoil of the revolutionary period. This study aims to explain the social and economic dislocation experienced by the Chinese community as part of a domestic humanitarian disaster. The approach used is a historical method with qualitative analysis based on archival sources, government reports, and contemporary documents. The results of the study show that the displacement was not merely the result of ethnic conflict, but a reflection of a power vacuum and widespread socio-economic tensions. Despite suffering great losses, the Chinese community was able to survive through internal solidarity, community assistance, and adaptation to the new post-war economic structure. This study confirms that the struggle for independence not only brought about political freedom but also left deep social wounds for Indonesian civilians, including those who had been an integral part of Javanese society. This research offers a new perspective by integrating colonial archival sources, visual data, and Karl Polanyi's disembedding theory to understand displacement as a form of domestic socio-economic disaster during the revolution, a theme that has not been widely discussed in Indonesian historiography
SELF REPORTED OF HEALTH LITERACY, PHYSICAL ACTIVITY AND SLEEP QUALITY: A CORRELATION ANALYSIS AMONG ELDERLY PATIENT AT PUBLIC HEALTH CENTER
No full textDecreased physical activity and sleep disorders are common problems among older adults. Health literacy is thought to play a role in motivating healthy behaviors, but its relationship with physical activity and sleep quality among older adults in Indonesia has been little studied. The purpose of this study was to analyze the correlation between health literacy, physical activity, and sleep quality among older adults at a community health center. This study used a quantitative cross-sectional research method with 35 elderly respondents aged ≥ 65 years at the Lidah Kulon Community Health Center. Sampling was conducted using accidental sampling. Data were collected through guided interviews using the HLS-EU-Q16 health literacy, PASE physical activity, and PSQI sleep quality questionnaires. Data analysis used the Spearman Rank correlation test. The results of this study showed that most respondents were female 65.7% and aged 66-74 years 62.9%. No significant relationship was found between health literacy and physical activity (r=0.054; p=0.760) or sleep quality (r=-0.187; p=0.280). However, a strong and significant negative relationship was found between physical activity and sleep quality (r=-0.721; p=0.000). The conclusion of this study is that health literacy is not directly correlated with physical activity or sleep quality among the elderly at this health center.Pengetahuan yang baik di kalangan masyarakat, khususnya pada kelompok lansia mengenai literasi kesehatan, aktivitas fisik dan kualitas tidur dapat meningkatkan kualitas hidup yang baik. Tingkat kebugaran fisik maupun psikis lansia secara signifikan dipengaruhi oleh jumlah aktivitas fisik dan kualitas tidur manula. Maksud dan tujuan penelitian ini adalah untuk mengetahui korelasi antara literasi kesehatan, aktivitas fisik dan kualitas tidur pada pasien lansia. Terdapat 35 sampel dengan kriteria usia ≥65 tahun yang telah melakukan pemeriksaan di Puskesmas dan telah menyelesaikan jawaban atas pengetahuan mereka mengenai literasi kesehatan (HLS UE-Q16), aktivitas fisik (PASE), dan kualitas tidur (PSQI). Studi ini menemukan bahwa nilai rata-rata literasi kesehatan (14.31±2.323) dengan kategori literasi kesehatan memadai pada pasien lansia laki-laki yaitu 25,71% sedangkan pada pasien lansia perempuan 57,13%. Berdasarkan hasil aktivitas fisik diperoleh nilai rata-rata (176.35±86.02) dengan kategori aktivitas fisik baik pada pasien lansia laki-laki 11,43% sementara pada pasien lansia perempuan 34,29%. Menurut hasil nilai rata-rata kualitas tidur diperoleh (5.66±1.301) dengan perolehan klasifikasi kualitas tidur baik pada pasien lansia laki-laki yaitu 11,43% sedangkan pada pasien lansia perempuan 34,29%. Hubungan aktivitas fisik dan kualitas tidur pasien lansia membuktikan dengan nilai (r=-0.721**) dan p-value (0.000), yang berarti sangat signifikan. Maka hasil tersebut dapat dikatakan adanya korelasi yang sangat kuat dan signifikan antara aktivitas fisik dan kualitas tidur dengan arah hubungan negatif. Sehubungan dengan hal ini aktivitas fisik yang dilakukan secara teratur dapat memberikan manfaat yang signifikan terhadap kualitas tidur. Namun, penting untuk mencatat bahwa baik kekurangan maupun kelebihan aktivitas fisik dapat berpengaruh negatif pada kualitas tidur. Kurangnya aktivitas fisik seringkali menyebabkan tubuh tidak cukup lelah untuk tidur nyenyak, sementara kelebihan aktivitas fisik terutama menjelang waktu tidur dapat menyebabkan tubuh terlalu terstimulasi dan sulit untuk rileks, sehingga mengganggu pola tidur. Oleh karena itu, menjaga keseimbangan dalam aktivitas fisik sehari-hari sangat penting untuk memastikan tidur yang berkualitas.

Pengaruh Latihan Resistance Band Dan Balance Board Terhadap Tendangan Dwi Hurigi Pada Atlet Warrior Taekwondo Club Kota Palopo
No full textThe double hurigi kick, as a complex taekwondo technique, requires explosive power and dynamic balance, but is often difficult for adolescent athletes to perform. This study aims to analyze and compare the effectiveness of resistance band and balance board training on improving double hurigi kicking ability. Using a quasi-experimental method with a pretest-posttest two-group design, the sample consisted of 20 Warrior Taekwondo athletes aged 13-17 years who were divided into two groups. The intervention was conducted for 8 weeks with a frequency of 3 times per week, and the research instrument was a dwi hurigi kick accuracy test within 30 seconds. The data were analyzed using a paired sample t-test and an independent sample t-test. The results showed a significant improvement in both groups. The resistance band group experienced an average increase of 3.40 points (Cohen's d = 4.86), while the balance board group increased by 2.00 points (Cohen's d = 3.00). Intergroup comparison analysis showed a significant difference (p = 0.029) with resistance band training having the advantage. Discussion revealed that resistance bands were more effective because they specifically increased the rate of force development and optimized the stretch-shortening cycle, which is essential for explosive kicks. It was concluded that although both were effective, resistance band training was significantly superior in improving double kick performance in adolescent taekwondo athletes.This study aims to determine the effect of Resistance Band Training and Balance Board Training on Dwi Hurigi Kicks in athletes of the Warrior Taekwondo Club in Palopo City.
