Abstract

The advancement of digital technology has reached various regions in Indonesia, including Sumberjaya Village, where internet access—particularly through smartphones—is widely available. While digital media offers numerous benefits, it also presents potential risks. Therefore, understanding appropriate usage guidelines, communication ethics, and information filtering is essential to minimize negative impacts. This community outreach program employed a participatory group method consisting of four main stages: observation, presentation, focus group discussion (FGD), and evaluation. The results of the program indicate that participants have significantly improved their digital literacy across three core dimensions: technological proficiency, cognitive awareness, and ethical behavior. These enhancements are expected to contribute positively to the community’s overall quality of life and resilience in navigating digital environments. Kemajuan teknologi digital telah merambah berbagai daerah di Indonesia, termasuk Desa Sumberjaya, yang akses internetnya sudah sangat luas, khususnya melalui telepon pintar. Media digital menawarkan banyak manfaat, tetapi juga berpotensi menimbulkan risiko. Oleh karena itu, pemahaman tentang pedoman penggunaan, etika komunikasi, dan penyaringan informasi yang tepat sangat penting untuk meminimalkan dampak negatif. Program pengabdian masyarakat ini menggunakan metode kelompok partisipatif yang terdiri dari empat tahap utama: observasi, presentasi, diskusi kelompok terfokus (FGD), dan evaluasi. Hasil program menunjukkan bahwa peserta telah meningkatkan literasi digital secara signifikan dalam tiga dimensi inti: kemahiran teknologi, kesadaran kognitif, dan perilaku etis. Peningkatan ini diharapkan dapat memberikan kontribusi positif terhadap kualitas hidup masyarakat secara keseluruhan dan ketahanan dalam mengarungi lingkungan digital.

Abstract

Waste management remains a pressing challenge in modern society, largely due to limited public awareness regarding its importance. This study offers a transformative approach by redefining waste—particularly organic waste—not as mere refuse, but as a potential economic asset. Although biodegradable, organic waste is often left untreated, leading to missed opportunities for resource recovery. This research highlights the utilization of eco-enzyme, a product of organic waste fermentation over a three-month period, as an innovative and sustainable waste treatment method. The resulting eco-enzyme liquid functions effectively as a natural cleaning agent and soil enhancer, contributing to environmental restoration by reducing heavy metal content and stabilizing soil pH. From an economic standpoint, the use of eco-enzyme reduces dependence on conventional cleaning products, thereby lowering household expenses. Overall, the findings advocate for a paradigm shift in organic waste handling—demonstrating its dual value in environmental improvement and economic efficiency—while laying the groundwork for more sustainable waste management models.  Pengelolaan limbah masih menjadi tantangan yang mendesak dalam masyarakat modern, terutama karena terbatasnya kesadaran masyarakat mengenai pentingnya limbah. Studi ini menawarkan pendekatan transformatif dengan mendefinisikan ulang limbah—khususnya limbah organik—bukan hanya sebagai sampah, tetapi sebagai aset ekonomi yang potensial. Meskipun dapat terurai secara hayati, limbah organik sering kali tidak diolah, sehingga menyebabkan hilangnya peluang untuk pemulihan sumber daya. Penelitian ini menyoroti pemanfaatan eko-enzim, produk fermentasi limbah organik selama periode tiga bulan, sebagai metode pengelolaan limbah yang inovatif dan berkelanjutan. Cairan eko-enzim yang dihasilkan berfungsi efektif sebagai agen pembersih alami dan penambah tanah, berkontribusi pada pemulihan lingkungan dengan mengurangi kandungan logam berat dan menstabilkan pH tanah. Dari sudut pandang ekonomi, penggunaan eko-enzim mengurangi ketergantungan pada produk pembersih konvensional, sehingga menurunkan pengeluaran rumah tangga. Secara keseluruhan, temuan tersebut menganjurkan perubahan paradigma dalam penanganan limbah organik—yang menunjukkan nilai gandanya dalam perbaikan lingkungan dan efisiensi ekonomi—sambil meletakkan dasar bagi model pengelolaan limbah yang lebih berkelanjutan.

Abstract

In general, coal fossil fuel reserves are the main load in the industry, especially in the use of boiler engines. Coal comprises carbon, hydrogen, oxygen, nitrogen, sulfur, and mineral compounds. A boiler engine is a machine that produces high-pressure water vapor by heating water through fuels such as coal. The water vapor can then be used for various purposes, such as heating oil in the oil manufacturing industry, especially PT. Meadow Rays. Steam is an effective and inexpensive medium for transferring heat to a process. Coal plays an important role in the operation of boiler engines because coal is one of the fuels that is often used in the heating process. The quality of the coal can affect the quality of the steam produced by the boiler engine. Suitable coal shape for boilers at PT. Meadow rays are generally solid or solid, such as chunks, fractional coal, or bituminous coal that has a large coal size that has a mesh size between 3.2 mm to 6.3 mm or about 1/8 to 1/4 inch. This is because the solid, dense form of coal has a higher density and lower porosity, so it can retain heat better and provide a smaller surface for the combustion process. Coal users must be provided to PT. Sinar Meadow must have a minimum calorie of 6300 kcal/kg, for the efficiency and safety of the boiler at PT. Meadow Rays. Therefore, paying attention to the coal quality used in boiler engines is important to produce high-quality and efficient steam.

Abstract

This study constructs an SVIR-type COVID-19 spread model into a model with control variables or optimum control problems. In the formulation of the model with controls, we set four control variables, namely vaccination strategy, quarantine, reduction of vaccine shrinkage, and treatment. Pontryagin 's maximum principle is applied in the model as a sufficient condition to achieve optimum conditions for minimizing the objective function . This study uses a numerical solution to describe the theoretical results. The results showed that the control model could accelerate the decrease in the number of individuals in the infected population class. We found that vaccination is a top priority that needs to be done to reduce the number of cases of COVID-19 infection. In addition, the implementation of quarantine can also be considered to accelerate the decrease in the number of individuals infected with COVID-19.

Abstract

This article implements the thinning process algorithm, which has been generalized for estimators of compound periodic Poisson processes. The use of generalizations in the algorithm has been prepared with a linear trend in the periodic elements. This research aims to discuss estimators of the variance function. The method used in this research is the simulation method. Simulation results using a generalized algorithm thinning process show that in the case of a limited observation time interval, some estimators are good enough to approach the actual value. As the value of n increases, the simulated value of the estimator moves towards the predicted value. This is following the lemmas, theorems, and consequences that have been discussed. It was also found that several estimators were quite slow. This results in the movement of the bias, variance, and MSE values of the estimators being slow, even though they are moving towards 0. So that further modifications can be made to the model being studied.

Abstract

This study develops an optimal bonus–malus premium model within a Bayesian decision-theoretic framework. Claim frequency is modeled using a Poisson distribution, while the number of claims exceeding a predefined critical threshold is modeled conditionally using a Binomial distribution. The Poisson intensity parameter is assigned an Exponential prior distribution, while the Binomial probability parameter follows a Beta prior distribution. The Exponential and Beta distributions are applied to model parameters rather than to observed data, ensuring probabilistic consistency. Since the Exponential distribution is a special case of the Gamma distribution, the Bayesian updating process remains mathematically coherent. To illustrate the model, a dataset of 1,000 simulated motor vehicle policyholders is generated in R under specified distributional assumptions. The results indicate that premiums increase with the number of claims exceeding the critical value and decrease with longer claim-free duration. The proposed framework provides a coherent and flexible approach for premium determination in bonus–malus systems. However, the findings are based on simulated data and specific modeling assumptions, which may limit direct empirical generalization.

Abstract

The majority of the community in Kubangsari Village, Cilegon City, are farmers and factory workers, with approximately 20% of the population directly dependent on the corn farming sector. Traditionally, corn harvests have been sold raw at prices around IDR 8,000, leaving farmers vulnerable to economic fluctuations, particularly during the rainy season when fields are prone to flooding. This community service program aims to empower the Kubang Lestari Women Farmers Group (KWT) through the innovation of processing purple corn into a functional health beverage named JAJANTAN (Jahe Jagung Anti Oksidan/Ginger Corn Antioxidant). The implementation method spanned one month, involving field surveys, direct production workshops, and assistance in packaging and halal certification. The results demonstrated a significant increase in the added value of agricultural commodities; raw corn was transformed into a ready-to-sell bottled beverage priced at IDR 10,000 per unit, with a production cost of IDR 7,000. This mentorship has successfully increased public knowledge regarding food product diversification and opened opportunities for the development of local Micro, Small, and Medium Enterprises (MSMEs), with full support from the local village government.
