In this study, we investigate the classification of lung cancer CT scan images based on malignancy level using a backpropagation artificial neural network (ANN). Lung cancer is a deadly disease characterized by the growth of abnormal lung cells. The proposed method involves preprocessing to enhance image quality, followed by feature extraction using the Gray Level Co-occurrence Matrix (GLCM) method with angle variations of 0°, 45°, 90°, 135°, and d=1. The extracted features include energy, contrast, correlation, and homogeneity. The energy value range in malignant cancer is 0.27 to 0.81, while in benign cancer it is 0.26 to 0.73. The contrast in benign cancer ranges from 1.38 to 11.87, while in malignant cancer it is 1.47 to 13.67. The image correlation for malignant cancer is between 0.63 to 0.94, while for benign cancer it is 0.69 to 0.96. Homogeneity in malignant cancer has a value range between 0.67 to 0.91, while in benign cancer it ranges from 0.70 to 0.92. The classification of lung cancer malignancy is restricted to benign and malignant levels using a network architecture of [4 10 2], maximum iteration of 100000, and learning rate of 0.001. The accuracy of the testing data from the ANN is between 90% and 100%. These results demonstrate the effectiveness of the GLCM method and backpropagation algorithm in accurately classifying the malignancy level of lung cancer, which could aid in the early detection and treatment of the disease.

One of the activities of professional development for teachers is Scientific Publication. Nonetheless, many teachers have a problem with writing scientific work. Therefore, this community service was done to improve the teachers’ scientific publication through the writing process of a scientific article for journal publication. The type of community service in this research is Participatory Action Research (PAR). The activity of this community service was to provide training/assistance for improving the scientific publication. It was conducted in the form of providing training in article writing for the journal to the teachers in Islamic schools in Teluk Kuantan, especially MAN 1 Teluk Kuantan and it involved 25 teachers. The result of this community service was that the teachers as the training participants had a minimum initial understanding of journal articles and the use in improving learning quality in a class. The average indicator as a whole was only 23.725 and it was categorized as infrequent. All indicators that were questioned were in the ‘infrequent’ category. Meanwhile, based on gender-based motivation, it was found that both genders of the training participant had a motivation that was categorized as ‘frequent’ in participating in the training. However, there was a difference in the aspect for the indicator of being confident to be able to participate well and the readiness of sufficient basic knowledge. The implication of this community service is the importance of this activity and the like for the people to change the mindset and the understanding of the teachers as the training participants to be better.

Indonesia comprises various ethnic cultures, which has its own uniqueness. One element of culture is a livelihood system. The Minangkabau ethnic community has a uniqueness that is represented by the tradition of migrating and the livelihood system of trading. Migrants were initially only carried out by men but later were also joined by women. Many Minangkabau women migrants are successful in their overseas and trading businesses. This prompted this research to be carried out with the title Minangkabau Woman Creativepreneurship. This paper applies qualitative approach, with ethnographic research methods and an anthropolinguistic paradigm. The informants in this research were 10 Minangkabau women who were creative in running their businesses. The location of this research is Dharmasraya Regency, West Sumatra Province. This research found 7 (seven) Minangkabau Woman Creativepreneurship values, namely: (1) religiosity, (2) hard work, (3) discipline, (4) honesty, (5) never giving up, (6) thriftiness, and (7) creativity.

The plurality of Indonesia with more than 600 ethnics is a great wealth but has not been adequately rewarded. Various political, legal, and socio-cultural events have resulted in the degradation of diversity from a colorful mosaic to a blur. This article analyzes the discourse of ‘return to nagari’ based on texts of national commitments and policies on decentralization, West Sumatra’s local policies on the lowest government ‘nagari’, and public responses on them. The methods had been used are literature study and field research, which are analyzed based on the technique of discourse analysis which included text, context, and social practice. The findings are the policy on decentralization is still inconsistent, and the construction of the regional government’s policy based on local culture has not been ideal and operational formulated yet. In fact, it is not easy to return to indigenous culture as roots the Beauty of Indonesia’s Multiculturalism. This finding reflects the critical implication of the discursive practice that shows the awareness of actor’s membership in their culture that leads them to make clear cultural-political attitudes in relation to the state. The position of their cultural traditions is threatened and our position is to mobilize them to revive, maintain, keep, consolidate and revitalize their cultural identity.

BACKGROUND: The implementation of Sharia Model Childbirth (SMC) is in accordance with Fatwa Majelis Ulama Indonesia (MUI) no l07/DSN-MUI/X/2016 on the practice of sharia principles in health services. Sharia services in hospitals are general. This SMC innovation is specific and comprehensive, covering prenatal, delivery and postnatal. This model was implemented in 2017 but has never been qualitatively evaluated. The purpose of this study was to evaluate the application of SMC in the maternity services from the perspective of midwives and staff of the Islamic service unit. MATERIALS AND METHODS: Applied qualitative research was conducted from 5 December 2021 to 31 January 2022. In-person in-depth interviews were conducted using semi-structured interview guidelines. Informants were taken from the midwives of the maternity room and the Islamic service installation until a fair saturation of data was achieved. Observational and documentation were conducted for the validity of the data. The data were analyzed thematically and presented in themes and sub-themes. RESULTS: The results of the study were on the work procedures implemented, and the obstacles and shortcomings found. Most of the procedures and accompanying regulations had been implemented. Participants revealed obstacles and shortcomings in this innovative program. The major obstacle found was that the patient's right to choose a female medical officer was not fulfilled because of the type of teaching hospital it was and the lack of female medical staff. The shortcomings were in the reading of prayers and remembrances, the understanding of the contents of the manual, and the design of the delivery room, which did not maintain privacy. CONCLUSION: Overall, SMC is being implemented, but there are obstacles and shortcomings in the implementation. Solutions and regulations in sharia services should urgently be found and enforced. The deficiencies in this innovative program must be corrected immediately.

This study aims to find out how to implement problem solutions to bullying behavior that tends to occur in Islamic educational institutions. Islamic educational institutions, which in their curriculum are ensured to have a lot of character education content, are considered not optimal in giving strict sanctions to students who are perpetrators of bullying and all other dishonorable acts. This research uses a qualitative descriptive approach. To obtain research data, researchers used open interview techniques with informants. The participants in this study were students from 4 Integrated Islamic Middle Schools in Medan City, totaling 4 students. Data triangulation techniques were also used in this study by checking records from interviews, field notes, surveys and also documentation records from various data obtained. The results of the study show that bullying that occurs in several Integrated Islamic schools does not receive serious attention, teachers and schools often ignore this behavior by not providing consequences or punishments so that bullies feel rewarded or empowered for their actions. The school should not tolerate the slightest bit of disgraceful actions committed by students so that it becomes a deterrent effect for other students and parents are also required to be responsible for providing good ethical education in the family. teachers and schools often ignore this behavior by not giving consequences or punishments so that bullies feel rewarded or empowered for their actions.

Penelitian ini mengkaji orbit, galat energi, dan besaran aksi dalam simulasi planet mengorbit bintang dengan menggunakan metode leapfrog dan langkah waktu konstan. Sebuah modul program dibuat dalam bahasa pemrograman Python 3. Nilai posisi dan kecepatan awal planet diatur sedemikian rupa sehingga eksentrisitas orbit bernilai 0,75. Hasil simulasi menunjukkan galat energi yang memiliki nilai batas tertentu yang cenderung konstan. Secara visual, nilai besaran aksi yang diwakili oleh luas daerah yang dibatasi oleh kurva ruang fasa tidak berubah. Hal ini disebabkan oleh sifat time-symmetric dan symplectic dari metode leapfrog. Akan tetapi, pergeseran fasa orbit tetap terjadi. Sebagai perbandingan, metode Runge-Kutta orde 2 yang tidak time-symmetric dan non-symplectic menghasilkan galat energi dan besaran aksi yang meningkat secara linier. Selain itu, pergeseran fase metode Runge-Kutta orde 2 terlihat lebih besar dari pergeseran fase metode leapfrog. Hal ini menunjukkan metode leapfrog sangat cocok dipakai untuk simulasi planet dalam jangka waktu yang sangat lama.

Penelitian ini meninjau galat energi dan galat fase dari metode forward 4th order symplectic Chin-Chen (F4OS-CC) untuk kasus sistem osilator harmonik sederhana. Metode F4OS-CC merupakan suatu integrator yang bersifat symplectic dan time-reversible tanpa menggunakan selang waktu negatif. Simulasi osilasi harmonik sederhana dengan metode integrasi F4OS-CC dan metode Leapfrog menghasilkan galat energi terikat (tidak memiliki rambatan linier). Akan tetapi, metode F4OS-CC memiliki galat fase yang lebih besar jika dibandingkan dengan metode non-symplectic orde sama (metode Runge-Kutta orde 4). Galat fase dapat dikurangi dengan menggunakan selang waktu variabel yang bergantung terhadap posisi. Tetapi, rambatan galat energi menjadi meningkat secara linier.
