Abstract

Cervical cancer is the most common cancer that causes death in women. This cancer is mainly caused by Human Papilloma Virus (HPV). It is estimated that 52 million of Indonesian women are at risk of having cancer, and 36% of female cancer patients suffer from cervical cancer. This type of cancer cannot be diagnosed immediately as there is several years of pre-malignancy phase; thus, early detection or screening is needed to prevent it from turning into malignant. Pap test as a screening program can detect cancer, precancer, and normal condition. To understand the predicting factors of the test results, a comprehensive mathematical modelling was created using the link function of Bayesian Ordinal Logistic Regression. This study observed several possible factors that may affect Pap test results in Tuban regency, namely Age (X1), Education (X2), Childbirth Experience (X3), Use of Contraceptives (X4), Menstrual Cycle (X5), Age of First Menstruation (X6), History of Miscarriage (X7), Anemia (X8) and Number of Sexual Partners (X9) . The outcomes indicated that the predicting factors of Pap cervical cancer results are Age (X1), Education (X2), Childbirth Experience (X3), Use of Contraceptives (X4), Menstrual Cycle (X5), and Anemia (X8). In this model, there is an inexplainable error dependency as indicated by the varied constance values of alpha.

Abstract

AIDS (Acquired Immuno Deficiency Syndrome) is is a symptom of blood cell disease which results in decreased immunity in humans. HIV/AIDS causes a decline in economic productivity, health, and environmental fields, so it needs treatment to reduce the spread of the disease in East Java. The spread of the HIV/AIDS virus is growing rapidly both in terms of region and pattern of spread. Therefore, it is necessary to have policies from the government to prevent the spread of HIV/AIDS through mathematical modeling to determine the actual and comprehensive factors that influence HIV/AIDS care. policies needed to handle and reduce HIV/AIDS in East Java. This study aims to determine the factors that influence the care of people with HIV/AIDS with Survival Regression modeling Dagum 3 Parameter link function. This model uses parameter estimation with a Bayesian analysis approach with the results that the factors that significantly influence the length of HIV/AIDS care in East Java are marital status (X5), absolute CD4 levels (X7), Suffering Stage (X8), Functional State (X9), and Therapy adherence (X10). These results indicate that marital status and condition characteristics of HIV/AIDS sufferers are important information in the socialization program for reducing HIV/AIDS in East Java.

Abstract

The heart is a vital organ in the human body that functions to pump blood throughout the body and to the lungs. The heart is located in the chest cavity. The heart is the main force that drives human life. Therefore, if there is a disturbance in heart function, this can cause a decrease in quality of life to death, one of which is heart failure. Heart failure, if not diagnosed and treated quickly, will result in death. Based on findings showing the high death rate due to heart failure, a classification is needed to predict heart failure using machine learning methods. Machine learning can help predict this disease to improve early detection and more accurate medical decision-making. This study focuses on predicting the likelihood of a patient experiencing heart failure. The machine learning algorithm method used is supervised machine learning classification, including decision trees, random forests, naïve bayes, SVM, and K-NN. The results showed that the best method for predicting heart failure was Random Forest with an accuracy of 74.35%, followed by SVM with an accuracy of 69.23%. Meanwhile, Naïve Bayes had the lowest accuracy of 51.28%. Based on these findings, Random Forest is recommended as the best method for heart failure prediction due to its ability to handle data complexity and provide more stable results. Once the best algorithm is obtained, the prediction results and early detection of heart failure will be more accurate.

Abstract

ABSTRAK Kemandirian siswa-siswi Taman Kanak-kanak (TK) dan Madrasah Ibtidaiyah (MI) masih rendah. Guru menjadi pembimbing dan pengganti orang tua saat kegiatan sekolah. Guru dituntut untuk memiliki kemampuan bidang akademik, dan non akademik berkaitan dengan kesehatan anak didik saat kegiatan di dalam dan diluar sekolah. Lingkungan sekolah sehat, ketersediaan perlengkapan kesehatan, personil guru yang kompeten dibidang Usaha Kesehatan Sekolah (UKS) dan Pertolongan Pertama Pada Kecelakaan (P3K) menjadi salah satu modal menciptakan lingkungan kondusif bagi anak didik. Guru penanggung jawab UKS sekolah Muhammadiyah tingkat TK dan MI di Kecamatan Gondangrejo belum pernah mendapatkan pelatihan khusus mengenai UKS dan P3K. Berdasarkan hal tersebut kami mengadakan pengabdian masyarakat melalui pelatihan Usaha Kesehatan Sekolah (UKS) dan Pertolongan Pertama Pada Kecelakaan (P3K) untuk Guru Sekolah Taman Kanak-Kanak dan Madrasah Ibtidaiyah Amal Usaha Muhammadiyah. Metode kegiatan berupa seminar, workshop, pembuatan buku panduan UKS, poster kesehatan, serta pembagian perlengkapan UKS dan P3K. Peserta pelatihan adalah perwakilan guru dari TK dan MI Muhammadiyah se-kecamatan Gondangrejo Kabupaten Karanganyar. Peningkatan kompetensi dapat diberikan dengan pemberian pengetahuan dan pelatihan. Nilai postes lebih tinggi dibanding nilai pretes. Menciptakan sekolah sehat merupakan tanggung jawab seluruh civitas sekolah, baik guru, siswa, karyawan sekolah, maupun orang tua siswa.   ABSTRACT The independence of kindergarten (TK) and Madrasah Ibtidaiyah (MI) students is still low. Teachers act as mentors and substitutes for parents are required to have academic and non-academic skills related to the health of students during activities. A healthy school environment, the availability of health equipment, and teaching staff who are competent in School Health Services (UKS) and First Aid (P3K) are some of the factors that contribute to creating a conducive environment for students. Teachers in charge of UKS at Muhammadiyah kindergarten and MI levels in Gondangrejo Subdistrict have never received special training on UKS and P3K. Based on this, we held a community service program through training on School Health Efforts and First Aid for Accidents for teachers. The methods used were seminars, workshops, the creation of UKS guidebooks and posters, and the distribution of UKS and P3K equipment. The training participants were teacher representatives from Muhammadiyah kindergartens and elementary schools in the Gondangrejo sub-district of Karanganyar Regency. Competency improvement can be achieved through the provision of knowledge and training. The post-test scores were higher than the pre-test scores. Creating a healthy school is the responsibility of the entire school community, including teachers, students, school employees, and parents.

Abstract

ABSTRACTThe COVID-19 pandemic has had an impact on various sectors, especially in the economic sector. This also happened in areas in Bojonegoro Regency, including Tapelan Village. Tapelan village has a large area of land planted with rice and corn, there are also land or yards of residents' houses, most of which are classified as large and are also used for planting. One of the plants grown by the Tapelan community in their land is Moringa (Moringa oleifera). In the international world, the cultivation of Moringa leaves is an ongoing program. There are several nicknames for Moringa trees including The Miracle Tree, Tree For Life, and Amazing Tree. The nickname arises because the parts of the Moringa tree from leaves, fruit, seeds, flowers, bark, stems, to roots have extraordinary benefits. The goal to be achieved in this community service activity is to improve the community's economy through the PKK group of women by providing food processing training with the basic ingredients of Moringa (Moringa oleifera) into products that have a high selling value. The method used is the provision of training to PKK women in Tapelan Village, Bojonegoro Regency, which begins with prior observation of the existing potential to analyze existing conditions in the community. The third stage is providing training on the use of Moringa (Moringa oleifera) leaves. The fourth stage is evaluation and continued with manufacturing assistance after the end of the training. The result of this service activity is the preparation of Moringa leaves (Moringa oleifera) into Moringa Sticks & Moringa Milk Shake.  ABSTRAKPandemi Covid-19 menimbulkan dampak di berbagai sektor, terutama dibidang ekonomi. Hal tersebut juga terjadi di wilayah di Kabupaten Bojonegoro, termasuk Desa Tapelan. Desa Tapelan memiliki lahan yang luas yang ditanami padi dan jagung, terdapat juga lahan atau pekarangan rumah warga yang sebagian besar tergolong luas juga digunakan untuk penanaman. Salah satu tanaman yang ditanam oleh masyarakat Tapelan di lahan adalah tanaman kelor (Moringa oleifera). Di dunia internasional, budidaya daun kelor merupakan suatu program yang sedang dijalankan.

Abstract

Welfare is one of the goals of the societies that make up the state. There are various ways to fulfill it, one of which is a cooperative. A cooperative is an association of people or entities that gives people the freedom to enter and leave as members, to work together in a family manner in running a business to fulfill or improve the welfare of its members. Mohammad Hatta as the originator of Article 33 of the 1945 Constitution has formulated his philosophical thoughts about the economic system of the Indonesian nation, he emphasized that the principle of kinship is cooperatives, this law is a working effort towards the national economy. Based on these provisions, cooperatives are a constitutionally valid system. At a macro level, cooperatives are envisioned as the backbone of the Indonesian economy based on the principle of kinship to create prosperity and community welfare. In its application, many cooperatives have succeeded, but also many have failed, some have stumbled over fraud cases and so on. Based on this, the question raised in this paper is, how is the ideology, concept and legal structure of cooperatives based on law in Indonesia in terms oEf the philosophy of economic law? To analyze it, the author uses the library research method by collecting valid and relevant data and then comparing, criticizing and analyzing, to draw the right conclusions. The theory of approach is the school of utulitarianism which argues that the purpose of law is the greatest welfare for the people, and legal evaluation is carried out based on the consequences resulting from the process of applying the law. Adherents of this school consider that the purpose of law is to provide as much benefit and happiness as possible to citizens. The purpose of law according to Jeremy Bentham is to realize the greatest happiness of the greatest number, aka the purpose of legislation is to produce happiness for society. Then what about the cooperative system as a system of national economic realization, whether this system by law has fulfilled the principles of utilitarianism. The result of this research is that happiness, defined as the general welfare, must be above all individual happiness in the eyes of the constitution. The argument is that the happiness of all people involved in an event or endeavor is not the happiness of one person alone, but includes all the happiness of its members in general. The happiness of one person should not be considered more important than the happiness of another, hence like the King and subordinates should be treated equally. Thus an action or endeavor is considered good when happiness outweighs unhappiness, and the happiness of everyone involved should be treated in the same way.

Abstract

Motorcycle key damage is often a problem for users, while the identification process still relies on technicians, which can be time-consuming and subjective. This study develops a classification system for motorcycle key damage levels using the Random Forest method with hyperparameter optimization. The dataset consists of 1,000 samples collected through observation and technician interviews, with data preprocessing using the SMOTE technique to address class imbalance. The model is trained and optimized with Random Forest using GridSearchCV and evaluated based on accuracy, precision, recall, and F1-score. The results show that the optimized Random Forest model achieves an accuracy of 85.5%, an improvement from 82% before tuning, enabling faster and more accurate identification of motorcycle key damage levels. The implementation of this system is expected to improve repair service efficiency and help users take action before the damage worsens.
