Abstract

Local food security must be continuously improved to compete in the global market. In addition to boosting income, local food products must ensure their halal certification. Halal certification institutions play a crucial role in guaranteeing product halalness. However, many micro, small, and medium enterprises (MSMEs) need to be made aware of the certification process, despite legal requirements mandating that all products in Indonesia be halal certified, including MSME products. This study explores the implementation of halal certification to support local food security in the global market. Data were gathered through literature reviews, direct observations, and interviews with MSMEs in Cilegon City, Banten, Indonesia. The study included workshops and ongoing assistance through the Untirta Halal Center to guide MSMEs in completing the halal certification process. The findings indicate that halal certification strengthens local food security and enhances the competitiveness of local products in the global market. Ketahanan pangan lokal perlu terus ditingkatkan agar mampu bersaing di pasar global. Selain sebagai upaya meningkatkan pendapatan, produk pangan lokal juga harus memastikan kehalalannya melalui sertifikasi yang sesuai. Lembaga sertifikasi halal berperan penting dalam memberikan jaminan kehalalan produk. Namun, masih banyak pelaku usaha mikro, kecil, dan menengah (UMKM) yang belum sepenuhnya memahami proses sertifikasi, meskipun peraturan mewajibkan semua produk di Indonesia, termasuk produk UMKM, memiliki sertifikat halal. Penelitian ini menganalisis penerapan sertifikasi halal sebagai langkah strategis untuk memperkuat ketahanan pangan lokal dalam menghadapi persaingan pasar global. Data dikumpulkan melalui kajian pustaka, observasi lapangan, dan wawancara dengan pelaku UMKM di Kota Cilegon, Banten. Penelitian ini mencakup pelaksanaan lokakarya serta pendampingan intensif melalui Halal Center Untirta, yang membantu UMKM menyelesaikan proses sertifikasi halal. Hasil penelitian menunjukkan bahwa sertifikasi halal tidak hanya memperkuat ketahanan pangan lokal, tetapi juga meningkatkan daya saing produk lokal di pasar global.

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 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 models the health service queue system at the Integrated Health Service Post (Posyandu) in Cilegon City, Banten, using the Petri Net and Max-Plus Algebra approaches to analyze the flow of participant arrivals and completion times. The data used are observational data from Posyandu activities simulated through a discrete event model, which includes several types of participants, namely: babies not standing yet, babies standing, pregnant mothers, and family planning programs. Petri Net modeling is used to represent the relationship between service transitions, while Max-Plus Algebra is used to calculate the process cycle time based on the critical path. The results of the study showed that the categories of non-standing babies, standing babies, and pregnant women/participants in the family planning program had identical service time patterns, namely a total duration of 17 minutes 19 seconds, with the main stages including measurement, midwife intervention, and provision of additional food. Max-Plus analysis confirms that the measurement and midwife intervention stages are the critical path that determines the length of service time. This study concludes that the combination of Petri Net and Max-Plus Algebra is effective in describing the dynamics of Posyandu queues and is able to provide quantitative information needed to identify bottleneck points and the basis for improving the service flow.

Abstract

This study investigates the effects of digital access and online training on teaching motivation, with technology self-efficacy as a mediating variable. Grounded in Social Cognitive Theory, the study integrates structural and psychological factors to explain teacher motivation in digital learning contexts. A quantitative explanatory survey was conducted involving 300 senior high school teachers in Tangerang Regency, Indonesia, selected using proportional random sampling. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with 5,000 bootstrap resamples. The findings indicate that digital access (β = 0.491, p < 0.001) and online training (β = 0.523, p < 0.001) significantly influence technology self-efficacy. Technology self-efficacy, in turn, significantly affects teaching motivation (β = 0.251, p < 0.001). However, the direct effects of digital access (β = 0.131, p = 0.057) and online training (β = 0.106, p = 0.081) on teaching motivation are not significant. Mediation analysis reveals that technology self-efficacy fully mediates these relationships. This study contributes to the literature by demonstrating that structural factors alone are insufficient to enhance teacher motivation unless internalized through efficacy beliefs. The findings provide practical implications for designing teacher development programs that prioritize mastery-based training and confidence-building strategies.
