Steel is part of raw material for manufacturing process making a product. Ferro Casting Ductile is part of manufacturing process from iron ore to be metal part using casting process. Die casting is a part of manufacturing process especially in automotive industries for engine of vehicle production process. this research will be focus on casting process, Ferro Casting Ductile (FCD). In this research using material steel HDF 12 Material, in this process production Magnesium, Pig Iron, Scrap, Silicon, Carburizer, Inoculant and Slagtol.  Manufacturing process is melting process of all raw material using temperature (melting point) at 1100 - 1400 ºC. When Specimen finish to process production will be analyze using spicrometer and SM machine for check of characteristic material and structure for crack issue. The result show that after casting process, the HDF12 have composition rate iron (Fe) content, namely 93.37% and also carbon (C) 3.82% and silicon (Si) 2.31% after check using. As visual check after die casting, lower arm is there no any crack, flash, flow mark finding by visual check inspection result. SEM Measurement check result until 300?m the result show that no any finding crack issue and result of Tensile strength of material Lower Arm upper limit is 433Kgf/cm2 and lower limit is 420 Kgf/cm and Elongation is 32%.

Hypertension is one of the major non-communicable diseases that has become a primary health concern, especially during the Covid-19 pandemic. Effective blood pressure control is crucial to prevent severe complications. The role of health cadres in monitoring blood pressure at home has become increasingly important, particularly with the application of non-pharmacological methods such as foot touch therapy and acupressure. This study aims to optimize the role of health cadres in assisting hypertensive patients to control their blood pressure using these techniques. The methods used include cadre training, patient education, and evaluation of intervention effectiveness. The results show that implementing foot touch therapy and acupressure can significantly reduce blood pressure and improve patients' well-being. Optimizing the role of health cadres in community-based hypertension management is expected to enhance patients' quality of life, especially in a pandemic situation that limits access to healthcare facilities.

Training in digital technology for elementary school teachers is a solution to enhance classroom management skills and teaching quality. This study aims to evaluate the impact of digital technology training on teachers' skills and social changes within the educational community. The methods used include initial surveys, practice-based training, and post-training evaluations with qualitative and quantitative approaches. The results show a significant improvement in teachers' technology skills and positive changes in classroom management. Teachers reported increased confidence and practical skills in using technology tools, and the formation of support groups and technology-based learning communities. The program also facilitated the emergence of local leaders who spearhead technology initiatives in their schools. These findings emphasize the importance of participatory and sustainable training in creating positive changes within the educational environment.

Obesity, characterized by excessive accumulation of body fat, increases susceptibility to chronic disease and adversely impacts overall quality of life. Elderly people often exhibit higher fat mass and lower muscle mass and bone density, influenced by reduced physical activity, hormonal changes, and metabolic adjustments. Visceral fat accumulation is of particular concern because of its association with metabolic syndrome, insulin resistance, diabetes, hypertension, and cardiovascular disease. This activity uses the PDCA (Plan-Do-Check-Act) framework to screen for obesity in the elderly using Body Mass Index (BMI) and waist circumference measurements. Activities were held at St. Fransiskus Assisi, Jakarta involving 36 participants. The study revealed that 16 participants (44.5%) and 30 people (83.3%) were obese and centrally obese, respectively. Early detection and intervention through anthropometric measurements are very important in managing health risks related to obesity in the elderly, so as to improve their quality of life and reduce morbidity and mortality.

Twitter is one of the media used by the Indonesian people to express their opinions regarding the 2024 Presidential Election. However, there is no scientific calculation that can determine the tone of public opinion regarding the 2024 presidential election. In this study, sentiment analysis was carried out on the tweets of the Indonesian people related to the 2024 Presidential Election (Pilpres 2024). The purpose of this study is to find out the opinions of Indonesian Twitter users regarding the 2024 Presidential Election using Natural Language Processing (NLP) Technology and Long Short Term Memory (LSTM) algorithms. NLP techniques are used to understand natural language and extract meaning from tweet copy, and LSTM is used to analyze the accuracy and accuracy of classification. The data used in this study was 1,004 tweets with the topic "Presidential Election", this data researchers obtained through the process of crawling using the tweet harvest library. In this study, 53.2% had positive emotions, 3.5% had neutral emotions, and 43.3% had negative emotions. 78% accuracy, 67% precision, and 67% recall.

GoPay as one of the digital payment applications in Indonesia faces challenges in understanding user perceptions in the midst of fierce competition. This study aims to develop a user review sentiment analysis model by comparing two approaches to text representation, namely TF-IDF and BERT, as well as two machine learning algorithms, namely Random Forest and Logistic Regression. Review data is obtained from the Google Play Store and processed through pre-processing, feature extraction, and sentiment modeling. The results showed that the combination of BERT + Logistic Regression provided the best performance with an F1 Score of 0.86, showing the superiority of BERT in understanding the semantic context compared to TF-IDF. An important feature analysis identifies financial-related words such as "duitnyaapakah" and "kompensasi" as key issues. This research makes a practical contribution by helping app developers improve the user experience through prioritizing relevant features and solutions to key problems complained of.

With the development of technology in communication, many applications make it easy to send messages. security in sending messages is something that cannot be excluded. E2EE (End-to-end encryption) is one of the most encryption for securing messages. in the discussion of literature review produces information on how applications such as whatsApp, Skype, Facebook messenger, line and viber implement E2EE in encrypting text messages specifically.

Penelitian ini bertujuan untuk meningkatkan kemampuan motorik halus anak-anak di Kelompok B TK Salafiyah Moga I, Kecamatan Moga, Kabupaten Pemalang. Hal ini didorong oleh masalah rendahnya kemampuan motorik halus anak di kelompok tersebut. Strategi pembelajaran yang kurang bervariasi dan stimulasi yang kurang optimal terhadap kemampuan motorik halus menjadi penyebab utama, di mana pembelajaran cenderung tidak memberi anak kesempatan untuk berekspresi. Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) dengan subjek siswa Kelompok B TK Salafiyah Moga I. Hasil penelitian menunjukkan adanya perbaikan yang signifikan setelah tindakan dilakukan. Setiap siklus pembelajaran yang menerapkan teknik kolase dari bahan alam menunjukkan peningkatan. Pengamatan terhadap rata-rata hasil tes kemampuan motorik halus anak secara keseluruhan menunjukkan bahwa pada observasi pra siklus, hanya sekitar 20% anak yang mencapai kemampuan motorik halus yang diharapkan. Persentase ini meningkat menjadi 40% pada siklus I, dan naik lagi menjadi 80% pada siklus II. Berdasarkan hasil tersebut, dapat disimpulkan bahwa teknik kolase efektif dalam meningkatkan kemampuan motorik halus anak usia dini di Kelompok B TK Salafiyah Moga I, Kecamatan Moga, Kabupaten Pemalang.
