Abstract

Rice plants with the Latin name Oryza Sativa are food plants that are widely used as the main food crop in various countries, one of which is Indonesia. Indonesia is ranked 4th as the largest rice consuming country in the world. This requires the availability of rice to be maintained. Unstable rice production can be a problem. One of the districts that has experienced a decline in rice production in recent years is the district of Lima puluh kota located in West Sumatra province. This requires prediction of rice production so that it can be used as a benchmark for the future. This study uses data on rice production in fifty cities from 2013 to 2023. The method used to predict is k-nearest neighbor regression (KNN Regression). The data division uses rasio 90 : 10. In testing the data used is divided into 2, namely normal data and data that has been normalized. The test results produce the smallest mean absolute percentage error (MAPE) value of 6.98% on normal data, the value of k is 6 with data division using k-fold 5. Based on the resulting MAPE value, it can be said that KNN Regression can predict rice production results very accurately.

Abstract

Kemampuan berbicara di depan publik menjadi kebutuhan utama bagi siapapun pada era kini tak terkecuali bagi remaja. Akan tetapi untuk mendapatkan kemampuan tersebut tidak mudah karena terbatasnya wahana. Salah satu peranan yang dapat dilakukan oleh kalangan akademisi adalah mengadakan pelatihan public speaking. Pelatihan public speaking merupakan salah satu upaya strategis untuk meningkatkan kepercayaan diri dan keterampilan komunikasi remaja, khususnya di wilayah pedesaan yang memiliki keterbatasan akses terhadap pelatihan formal. Kegiatan ini dilaksanakan di Dusun Ngelo, Desa Jetak Tulakan Pacitan Jawa Timur. Adapun peserta kegiatannya adalah remaja yang berada di berbagai dusun di Desa Jetak. Metode pelatihan terbagi dalam tiga tahap, yaitu: pengenalan materi dasar public speaking, penyusunan teks MC, dan praktik membawakan acara. Hasil kegiatan menunjukkan adanya peningkatan kepercayaan diri dan kemampuan berbicara peserta, baik dalam aspek verbal maupun nonverbal. Pelatihan ini juga menciptakan suasana belajar yang positif dan kolaboratif antarpeserta. Dengan pendekatan praktik dan umpan balik yang membangun, pelatihan ini efektif dalam membentuk keterampilan komunikasi remaja secara menyeluruh.

Abstract

Machine learning has the potential to support hematologists in classifying leukemia by identifying abnormal chromosomes and specific gene markers. One effective technique for feature selection is Variable-Length Particle Swarm Optimization (VLPSO), where its performance depends heavily on parameter control, specifically the inertia weight (w) and acceleration factors (c), which regulate the search process. In previous VLPSO, static types of parameter control were applied to the  Factor, and time-varying types were used by the   Factor. Although its results showed good performance in VLPSO, there was no separation in the treatment of training data and test data, leaving a gap in understanding their impacts for real-world applications.  This study explores how different parameter control strategies (static, time-varying, and adaptive) affect the performance of VLPSO with two comparison adaptive parameter control approaches, Adaptive 1 and Adaptive 2, in the VLPSO framework, each designed to dynamically adjust the control parameters w and c in different ways. The 10-fold cross-validation shows that VLPSO with an Adaptive one-parameter setting achieves better generalization with low train-test differences, especially in Decision Tree and Naïve Bayes classifiers, though with higher variability. Adaptive 2-parameter setting of VLPSO offers more consistent results with narrower variability across different settings. Static methods are the least reliable, while time-varying controls show moderate but unstable performance. Adaptive parameter tuning is recommended to improve VLPSO's stability, flexibility, and classification accuracy in biomedical applications. The results provide recommendations for parameter settings using an adaptive approach that has been proven to enhance the performance of VLPSO

Abstract

Purpose: Kidneys has an important role in the human excretory system. Unhealthy kidneys can affect kidney function. It is important to know the symptoms of chronic kidney disease. One data mining technique that can be applied is the classification technique to determine whether a person has chronic kidney disease or not based on the symptoms (attributes) obtained from medical records. The symptoms of chronic kidney disease obtained amount to 24 symptoms or attributes,Methods/Study design/approach: In this research, the classification of chronic kidney disease is performed using the information gain feature selection method and the KNN and MKNN classification methods. The number of data used is 400 data with 2 classes, namely chronic kidney disease (CKD) and non-chronic kidney disease (non-CKD).Result/Findings: Based on the test results, it was found that the hemo (Hemoglobin) attribute has the highest information gain value, which is 0.6255. The best accuracy for the KNN classification method is 96.61%, and for the MKNN method, it is 98%. Novelty/Originality/Value: The purpose of information gain feature selection is to choose features or attributes that significantly influence chronic kidney disease. Keywords: Chronic Kidney Disease, Information Gain, KNN, MKNN

Abstract

Pendidikan Islam memiliki peran strategis dalam membentuk manusia paripurna atau insan kamil, yaitu manusia yang seimbang antara dimensi spiritual, intelektual, moral, dan sosial. Artikel ini bertujuan mengkaji konsep pendidikan Islam sebagai sarana pembentukan insan kamil melalui pendekatan filsafat pendidikan Islam. Metode yang digunakan adalah studi kepustakaan terhadap literatur berbahasa Indonesia yang relevan dengan tema filsafat pendidikan Islam. Hasil kajian menunjukkan bahwa pendidikan Islam tidak hanya berorientasi pada transfer ilmu pengetahuan, tetapi juga pada pembinaan karakter, penguatan nilai-nilai ketuhanan, serta pengembangan potensi manusia secara menyeluruh. Dengan demikian, pendidikan Islam memiliki kontribusi fundamental dalam membentuk insan kamil yang mampu menjalankan perannya sebagai hamba dan khalifah di muka bumi.

Abstract

Introduction: Dysmenorrhea, or painful menstruation, is common and can interfere with women's activities. Although painkillers are often used to treat it, they have side effects (Harel, 2006, as cited in Rahayu & Nujulah, 2018). Ginger contains active compounds, such as gingerol and shogaol, that have anti-inflammatory and analgesic properties (Kashefi et al., 2014). The purpose of this study is to determine the effectiveness of ginger tea in reducing the intensity of dysmenorrhea in six nursing students. Methods: The study used a descriptive method with a case study approach. The sample consisted of six nursing students who experienced dysmenorrhea. The intervention was administered during the first three days of menstruation. Pain levels were measured using a Numeric Rating Scale (NRS) before and after the intervention. Results: The results showed a decrease in pain levels after the intervention. On a scale of 0 (no pain) to 10 (extreme pain), the average dysmenorrhea pain level reported by the students before the intervention was between 4 and 8. Conclusion: Providing ginger boiled water proved effective in reducing dysmenorrhea in students. This is due to ginger's gingerol content, which acts as a natural anti-inflammatory and analgesic agent. It can accelerate the healing process of wounds in the uterus caused by the shedding of the uterine wall during menstruationKeywords:  Dysmenorrhea, Ginger, Menstruation, Pain
