The World Health Organization (WHO) estimates that Mycobacterium tuberculosis, the single agent causing pulmonary tuberculosis (TB), infects 1.8 billion people, or around one-quarter of the world's total population. In Indonesia, there are an estimated 969,000 cases of pulmonary TB, including 443,235 reported cases. Prison is a high transmission site for pulmonary TB. Prison circumstances, such as high occupancy capacity, inadequate ventilation and nutrition, difficulties accessing health care, inadequate treatment, and weak patient immunity, are some of the variables influencing this. Knowledge on the origins, transmission, preventative strategies, and early diagnosis of pulmonary TB infection is essential for the prisoner in order to change attitudes toward pulmonary TB infection. This study used a descriptive approach to generate a description of the prevalence and risk factors for the spread of pulmonary tuberculosis in the Prison of Jember Class IIA. Based on the WHO-recommended screening technique, 4 male prisoners in the Prison of Jember Class IIA (8.5%) tested positive for pulmonary tuberculosis. There are various aspects that are difficult to include into environmental health standards, particularly infectious diseases like pulmonary tuberculosis, such as the density of people in a single cell room and the construction of the building and the services housed inside it. Policymakers must pay attention to the requirement to create appropriate isolation rooms and, at the very least, satisfy room standards for patients suffering from pulmonary tuberculosis.

Tuberculosis (TB), caused by Mycobacterium Tuberculosis (MTB) and transmitted through the air, primarily affects the lungs. In Aceh Province, the reported TB cases reached 41,596. Nutritional status is a pivotal factor influencing TB occurrence, as malnutrition can compromise immune function, increasing susceptibility to MTB. This study assesses TB patients' nutritional status based on BMI, malnutrition risk, and body weight changes during therapy. As quantitative research with a descriptive cross- sectional study design, the study used the medical records of outpatient pulmonary TB patients at the Pulmonary & TB-DOTS Polyclinic of TK—II Iskandar Muda Banda Aceh Hospital, who underwent intensive phase therapy from January to December 2023. Malnutrition risk screening utilizes the Malnutrition Universal Screening Tools (MUST) instrument. The study revealed a high prevalence of pulmonary TB cases, particularly among individuals aged 17-25. Based on the MUST instrument, patients over 60 showed a high risk of malnutrition, with the average patient having a MUST score of 3 (indicating high risk). Most patients experienced a significant increase in body weight during the intensive treatment stage. Weight gain significantly contributes to the success of tuberculosis treatment, influencing positive changes in the nutritional status of pulmonary tuberculosis patients.

Highlights: Calciferol has cardioprotective properties, and a severe deficiency of calciferol is associated with septic shock, a longer duration of mechanical ventilation and treatment in the intensive care unit, and mortality. The role of calciferol in critical conditions has been described in several research reports, but relatively little is known about its function in pediatric cardiac surgery. Abstract Calciferol is a micronutrient and a secosteroid hormone that plays a role in maintaining the health of bones and soft tissues in the body, such as the myocardium, as well as the immune system. Hypovitaminosis D has been reported to be associated with poor clinical outcomes and child mortality in pediatric intensive care units. Children with congenital heart disease (CHD) are vulnerable to critical conditions and require early intervention due to heart failure. This study aimed to investigate the influence of calciferol status on the clinical outcomes of pediatric CHD patients who underwent heart surgery. A systematic literature review was conducted using the electronic databases from PubMed, Elsevier, and Cochrane. This study included observational and randomized control studies that assessed the calciferol status of pediatric CHD patients undergoing cardiac surgery. From a total of 168 studies, 8 studies were selected for review. The preoperative and postoperative calciferol status as well as clinical outcomes following pediatric cardiac surgery were reviewed. According to the findings, most pediatric CHD patients suffered from calciferol deficiency prior to corrective heart surgery, which further decreased postoperatively and was associated with clinical outcomes in the intensive care unit (ICU). Preoperative calciferol supplementation has been reported to enhance serum calciferol levels and is associated with good clinical outcomes in pediatric patients undergoing cardiac surgery.

ABSTRACT This research was conducted with the aim to find out how the regulations related to the authority to collect taxes on hotels on board tours after the issuance of the HKPD Law and HPP Law. Taxes on hotels aboard tour boats so far have created a separate polemic regarding the authority of the tax collection agency authorized to collect this type of tax, namely, whether it is a Regional Tax which is the authority of the Regional Government or is it the Center which is the authority of the Central Government, this is because there is an object that is the same wedge between the hotel tax on the tour boat and the VAT on the tour ship itself. Where in Law Number 28 of 2009 it has not been specifically regulated regarding whether staying on a tour boat is part of the hotel tax. For hotels on board tours it is more appropriate to be collected by the Regional Government. In the preparation of laws related to local taxes in the future, to include hotel tax coverage from a more substantive point of view and includes the nature of the accommodation services business itself, which in the future will likely be very transformative, not only on ships, but also by train, car and other modes, for this reason, it is better not to be limited by a limited scope.

Bondowoso Regency have 14 priority communities by 2023 to accelerate stunting reduction, and Tamanan District is host to three of the fourteen villages.

This activity's population of interest is 31 families with children under the age of two in Tamanan District, devided into 3 villages: 9 children in Sumber Anom village, 11 children in Sumber Kemuning village, and the remaining 11 children in Kemirian village. This community service held in July-August 2023. Descriptive analysis is used in data analysis. Based on weight per age, 3.2% were severely underweight, 6.5% were underweight, 87.1% were normal weight, and 3.2% were at risk of being overweight. According to body length per age, 29% were severely stunted, 19.4% were short, and 51.6% were normal. A calculation of body weight per body length, 6.5% are extremely wasted, 3.2% are wasted, 64.5% are normal, 6.5% are at risk of being overweight, 3.2% are overweight, and 16.1% are obese. The results obtained based on body mass index per age were 3.2% severely wasted, 3.2% wasted, 64.5% good nutrition (normal), 16.1% at risk of overweight, 3.2% overweight, and 9.7% obesity. We conclude that this community service could optimize children monitoring and development by assisting stunted families through Elsimil application.

This study aims to reveal the discourse practices in the narrative of the Chinese Rebellion in the Indonesian History textbook. Having long disappeared from Indonesian historiography, the Chinese-Javanese alliance against the VOC, often called Geger Pacinan (1740-1743), has reappeared in history textbooks. Its presence needs to be studied to understand the discourse practices that are to be conveyed by the narratives that are constructed. This study's subject was the Chinese Rebellion text in the Indonesian History textbook for class XI SMA based on the 2013 Curriculum published by the Ministry of Education and Culture of the Republic of Indonesia in 2017. The Critical Discourse Analysis (CDA) method, according to Teun A. van Dijk, was used to analyze the dimensions of the text, social cognition, and the social context of the narratives that are the research subject. The result is that the report in the text dimension does not present the Chinese role through the history of the event as a whole. In the size of social cognition, it is found that there is a potential to strengthen the practice of discourse, which leads to the marginalization of the Chinese role. The social context dimension has not entirely shifted from the New Order paradigm, which harbored stereotypes against the Chinese. In conclusion, the text of the Chinese Rebellion requires the teacher’s role to make the deconstruction process in learning history meaningful for students, especially in internalizing the value of diversity for national integration.

Due to the widespread use of distributed data mining techniques in a variety of areas, the issue of protecting the privacy of sensitive data has received increasing attention in recent years. Privacy-preserving distributed data mining (PPDDM) focuses on decentralized data analysis without the disclosure of sensitive information from data owner. However, the previous PPDDM mostly works on a limited amount of labeled data. In contrast to the real world, unlabeled data is abundance and labeled data is scarce. The objectives of this paper are to study and to analyze privacy-preserving properties of semi-supervised learning (SSL) algorithm with the combination of labeled and unlabeled data, where data is distributed among multiple data owners. In this paper we propose a Privacy-preserving Distributed Data Mining (PPDDM) method by designing a reliable application of secure MPC to semi-supervised tri-training algorithms. We simulate the original tri-training algorithm and tri-training algorithm with secure MPC using a different types of classifiers and datasets. The simulation results show that tri-training in secure MPC has almost same accuracy compared to original tri-training algorithm. We also compare execution time in addition to performance evaluation of tri-training in secure and the original tri-training algorithms.

This study analyzes changes in the representation of the Chinese Indonesian or Tionghoa in history textbooks in Indonesia. There are two history textbooks under study, each published during the Guided Democracy and New Order periods. The focus of this study is on the topic of the Chinese people’s resistance to colonialism. A qualitative approach is used in this study with the Critical Discourse Analysis (CDA) method. The results show that there has been a change in the discourse of the representation of the Chinese Indonesian in history textbooks. During the Guided Democracy period, the Chinese were represented by a discourse of integration as part of the Indonesian nation which participated in the resistance against colonialism. During the New Order era, there was a change in political direction which encouraged assimilation with discriminatory practices against the Chinese. Prejudice and stereotypes against Chinese Indonesian people in Indonesia are strengthening. They were marginalized and removed from history textbooks. This research contributes to inclusive history education through the writing of history textbooks and their lessons which represent the Chinese Indonesian as part of diversity for national integration.

In Indonesia, the river water quality has been determined based on Government Regulation of the Republic of Indonesia No. 22 of 2021. This study aimed to determine the quality of surface water from the Damsari, Jabawi, Kleblow, and Komba Rivers in Jayapura Regency based on the monitoring data from 2016 to 2019. The CCME-WQI method is used to determine the status of rivers based on river water quality standards (class 1 to class 4). The results of the study showed that the parameters of water temperature, TDS, pH, NH3, NO3-, SO4-2, surfactant, oil/grease, Cr-(IV), Mn, Fe, Fecal Coliform, and Total Coliform were still in accordance with the quality standard. Meanwhile, TSS, COD, BOD, Total Phosphate, Hg, and Ni have exceeded the water quality standard, where the dominant pollutant source is an anthropogenic waste. On the basis of the WQI average value, the four rivers are not suitable as a source of drinking water (Poor-Marginal; 41.33 – 58.25). The Jabawi River can be used as a recreational facility, but it must be under special management (Fair; 69.75), while the other three rivers are not suitable (Marginal; 52.00 – 61.67). The Jabawi and Komba Rivers are in the Fair category (75.50 and 69.33) to support aquatic life, while the Damsari and Kleblow Rivers are in the Marginal category (59.00 and 61.25). The water quality of the four rivers is very good and suitable to be used as a water source for irrigation (Good category; 80.00 – 88.00). The strategies for controlling river water pollution and increasing the role of the government, stakeholders, and the community are needed.

Active learning is a technique for maximizing performance of machine learning with minimal labeling effort and letting the machine automatically and adaptively select the most informative data for labeling. Since the labels on records may contain sensitive information, privacy-preserving mechanisms should be integrated into active learning. We propose a privacy-preservation scheme for active learning using homomorphic encryption-based federated learning. Federated learning provides distributed computation from multiple clients, and homomorphic encryption enhances the privacy preservation of user data with a strong security level. The experimental result shows that the proposed homomorphic encryption-based federated learning scheme can preserve privacy in active learning while maintaining model accuracy. Furthermore, we also provide a Deep Leakage Gradient comparison. The proposed scheme has no gradient leakage compared to the related schemes that have more than 74% gradient leakage.

Background Lung cancer is still the main cause of cancer deaths. The high lung cancer mortality rate is caused by a diagnosis factor or therapy selection. The cell block cytology technique using fine needle aspiration (FNA) samples can provide immunocytochemical material that plays an important role in the differential diagnosis of lung cancer subtypes and in determining immunotherapy administration. This study aimed to determine the sensitivity and specificity of transthoracic FNA (TTFNA) cell block cytology in comparison with bronchial washing smears and TTFNA smears in diagnosing lung cancer. Methods This was a cross-sectional diagnostic study involving 26 subjects. All subjects had undergone bronchial washing and CT scan-guided fine needle aspiration followed by cell block preparation. Both direct FNA smears and cell blocks are useful in the diagnostic work-up of patients. Comparative statistical analysis of TTFNA cell block versus bronchial washing smear and TTFNA smear cytology was carried out using the McNemar test. Results Lung cancer was found in 15 patients (57.7%) using the TTFNA cell block technique. The sensitivity and specificity of the TTFNA cell block technique were 85.7% and 75%, respectively. There was no difference in the positivity value between TTFNA cell block technique of bronchial wash smear technique, and TTFNA smear on lung cancer diagnosis (p>0.05). Conclusions Transthoracic fine-needle aspiration in combination with the cell block technique has good sensitivity and specificity. The TTFNA can be used for immunocytochemical examinations in lung cancer diagnosis and therapy. This approach is valuable for providing individualized treatment and prognostic evaluations.

This paper presents an efficient and simple technique on reducing the false contour problem which often occurs in the JPEG decoded image. The false contour appears on JPEG decoded image while applying small quality factor. This problem induces unpleasant visual appearance. The proposed scheme exploits the usability of Halftoning-Based Block Truncation Coding (HBTC) approach on generating visual illumination to reduce the aforementioned problem. Three HBTC techniques, namely Ordered Dither Block Truncation Coding (ODBTC), Error Diffusion Block Truncation Coding (EDBTC) and Dot Diffused Block Truncation Coding (DDBTC), modify the DC components of all Discrete Cosine Transform (DCT) processed image on JPEG encoding stage. Experimental results show the proposed method superiority on JPEG false contour reduction. To further improve the JPEG decoded image quality, the proposed method utilizes the Gaussian kernel on replacing the DDBTC diffused kernel on spreading the error term. It assumes that the adjacent image blocks have a strong correlation in which high diffused coefficient should be applied on nearest adjacent neighbor. This paper extends the HBTC usability on JPEG false contour suppression.
