Abstract

A change in curriculum policy to the Independent Curriculum is something new for teachers. There are many teacher needs, especially knowledge and skill competencies in terms of preparing Independent Curriculum learning tools, which have not yet been accommodated. The development of knowledge and skills is very important in order to improve the learning process in accordance with the Independent Curriculum. One effort to develop teachers' pedagogical abilities is through training in preparing Independent Curriculum learning tools. This activity was carried out at SMPN 1 Majene, West Sulawesi, which was attended by 32 teachers. Activity stages include preparation, implementation, evaluation and report preparation. The result of this activity is that the level of teacher satisfaction after implementing the training on developing independent curriculum learning tools is in the very satisfactory category.

Abstract

The declining quality of drinking water sources due to contamination poses significant health risks, particularly in rural areas where public awareness about water quality and its impact on health is often limited. In Majene City and Campalagian Village, West Sulawesi, drinking water is predominantly sourced from wells and springs, but these sources have shown elevated levels of pollutants, such as manganese and coliforms, exceeding government standards. This study explores the relationship between water quality awareness and drinking water consumption behavior in these regions using Structural Equation Modeling-Partial Least Squares (SEM-PLS). Data were collected through household surveys and laboratory testing of water samples, focusing on physical, chemical, and biological parameters. SEM-PLS was employed for its ability to analyze latent variables and handle small sample sizes effectively. Results reveal that water quality awareness explains 78.6% of the variance in drinking water consumption behavior (R² = 0.786), with key indicators such as knowledge of water quality standards and contamination risks strongly predicting positive behavioral changes. Hypothesis testing confirmed a significant positive relationship (path coefficient = 0.887, p < 0.001), underscoring the importance of awareness in promoting healthy consumption behaviors. These findings highlight the need for targeted public education campaigns and policy interventions to improve water quality awareness and consumption practices. The study also contributes to the growing application of SEM-PLS in environmental and public health research, offering insights into the complex interplay between awareness and behavior. Future research should consider integrating socio-economic and cultural factors to develop a more holistic understanding of drinking water consumption patterns.

Abstract

Banyak obat potensial telah ditemukan dari produk alami laut (Marine Natural Product). Hal ini menunjukkan bahwa senyawa laut merupakan sumber penting dalam pengembangan dan penemuan obat. Meskipun banyak senyawa laut yang menunjukkan aktivitas biologis tertentu, hanya sedikit yang tercatat sebagai senyawa antibakteri. Oleh karena itu, menemukan senyawa yang berpotensi sebagai senyawa antibakteri dari organisme laut masih menjadi tantangan. Tujuan dari penelitian ini adalah untuk memanfaatkan pendekatan komputasi untuk menemukan senyawa antibakteri dari produk alami laut yang berpotensi menjadi obat. Penelitian ini berfokus pada penggunaan model Artificial Neural Network (ANN), Random Forest, dan XGBoost untuk melakukan klasifikasi berdasarkan kemiripan kimiawi antara senyawa produk alami laut di Indonesia dengan senyawa antibakteri. Untuk mengatasi ketidakseimbangan data, digunakan teknik resampling berupa SMOTE dan undersampling (US). Hasil penelitian menunjukkan bahwa akurasi XGBoost + SMOTE memiliki nilai yang paling tinggi, yaitu 98.89%, mengungguli model ANN 97.57%, Random Forest  (RF) 97.06%, serta model dengan resampling lain seperti ANN+SMOTE 98.67% dan RF + SMOTE 98.59%. Sementara itu, penerapan teknik undersampling menyebabkan penurunan akurasi secara signifikan, di mana XGBoost + US, RF + US, dan ANN + US masing-masing hanya mencapai 91.12%, 91.59%, dan 87.85%. Dari 73 senyawa biota laut, hanya senyawa yang memiliki CID 101767277 yang diprediksi sebagai senyawa yang potensial sebagai antibakteri.   Abstract Many potential drugs have been discovered from marine natural products. This suggests that marine compounds are essential in drug development and discovery. Although many marine compounds exhibit certain biological activities, only a few have been recorded as antibacterial compounds. Therefore, finding compounds with potential as antibacterial compounds from marine organisms remains a challenge. This paper aims to utilize computational approaches to discover antibacterial compounds from marine natural products that have the potential to become drugs. This research focuses on the use of Artificial Neural Network (ANN), Random Forest (RF), and XGBoost models to perform classification based on chemical similarity between compounds of marine natural products in Indonesia and antibacterial compounds. To overcome data imbalance, resampling techniques such as SMOTE and undersampling (US) were used. The results showed that the accuracy of XGBoost + SMOTE has the highest value, which is 98.89%, outperforming the ANN model 97.57%, Random Forest (RF) 97.06%, as well as models with other resampling such as ANN+SMOTE 98.67% and RF + SMOTE 98.59%. Meanwhile, the application of undersampling techniques caused a significant decrease in accuracy, where XGBoost + US, RF + US, and ANN + US only reached 91.12%, 91.59%, and 87.85%, respectively. Of the 73 marine biota compounds, only compounds that have CID 101767277 are predicted as potential antibacterial compounds.

Abstract

Medicinal plants contain inherently active ingredients. Such ingredients are beneficial to prevent and cure diseases, as well as to perform specific biological functions. In contrast to synthetic drugs, which is based on one single chemicals, medicinal plants exert their beneficial effects through the additive or synergistic action of several chemical compounds. Those chemical compound act on single or multiple targets (multicomponent therapeutic) associated with a physiological process. Active ingredients combinations show a synergistic effect. This means that the combinational effect of several active ingredients is greater than that of individual one acting separately. A network target can be used to identify synergistic effects of plants active ingredients. The method of NIMS (Network target-based Identification of Multicomponent Synergy) is a computational approach to identify the potential synergistics effect of active ingredients. It also assessess synergistic strength of any active ingradients at the molecular level by synergy scores. We investigate these synergistic on a Jamu formula for diabetes mellitus type 2. The Jamu formula is composed of four medicinal plants, namely Tinospora crispa , Zingiber officinale, Momordica charantia, and Blumea balsamivera. Our work succesfully demonstrates that the highest synergy scores on medicinal plants synergy can be seen in pairs of several active ingredients in Zingiber officinale. On the other hand, the synergy of pairs of active ingredients in Momordica charantia and Zingiber officinale posseses a relatively high score. The same occurs in Tinospora crispa and Zingiber officinale.
