In the era of globalization, strong economic development is a priority for every country, with a significant focus on the role of Micro, Small, and Medium Enterprises (MSMEs). Using a qualitative descriptive approach of the field research method through interviews by utilizing field research to evaluate Rempeyek's business feasibility study. This research highlights the fundamental contribution of MSMEs to the national economy, especially in addressing issues such as poverty, unemployment, and income distribution. The study emphasizes the importance of understanding market opportunities and capitalizing on them through innovative product offerings that appeal to consumers. One of these promising businesses is the culinary business "Rempeyek 4 Sekawan", a traditional Indonesian snack that has gained popularity in various demographics. The study identified the potential market for reampeyek businesses, especially with the increasing demand for local snacks that combine traditional flavors with modern innovations. However, dynamic market conditions present challenges that require a comprehensive feasibility analysis. Therefore, the results of the research on the 4 friends business are worthy of being carried out as a business opportunity by using analysis that covers various aspects, including market and marketing, finance, operations, production and technology, human resources, and legal considerations. By applying a SWOT analysis, this study aims to provide insight into the competitive position of Rempeyek 4 Sekawan's business, ensuring its sustainability and success in the market.

Alcoholic drinks are often the main factor in various crimes, including assault, robbery and murder. Excessive alcohol consumption can cause loss of self-control, which can lead to unlawful acts such as traffic accidents, rape, assault, theft and domestic violence. This behavior disturbs public peace and has the potential to hinder the achievement of several Sustainable Development Goals (SDGs), such as good health (goal 3) and peace and justice (goal 16). This article aims to analyze the influence of excessive alcohol consumption on increasing criminal acts and its relationship to achieving the SDGs. Using qualitative methods with a normative legal approach and literature study, this research examines legal norms, statutory regulations and other relevant legal documents. Data analysis was carried out descriptively to identify the relationship between alcohol consumption, criminal acts, and their impact on achieving the SDGs. The research results show that excessive alcohol consumption contributes significantly to the increase in violent crimes and is a risk factor in cases of domestic violence and sexual harassment. Apart from the negative impact on physical and mental health, drunken behavior also hinders the achievement of SDGs, such as goal 3, goal 5 (gender equality), and goal 16. Although regulations in Indonesia have attempted to regulate the consumption and distribution of alcohol, their effectiveness still requires improvement. It is hoped that with a comprehensive approach and stricter policies, the negative impacts of alcohol consumption can be minimized, supporting the achievement of sustainable development goals.

This journal examines the development strategies of silver craftsmen businesses in Bakalan, Mojodadi Village, Kemlagi District, Mojokerto, facing the risk of extinction. This Region, initially known as a center for silver craftsmen, now confronts serious challenges due to changes in market trends and modernization. The research aims to analyze the factors causing the threat of extinction and formulate appropriate development strategies. The research methods include surveys, interviews, and qualitative data analysis. The results indicate that factors such as changes in consumer preferences, lack of innovation in design, and insufficient marketing and distribution support have significantly impacted the decline in the performance of silver craftsmen in Mojodadi Village.

The Erlang distribution is a special case of the Gamma distribution with the k shape parameter and the λ rate parameter. In this study, the parameter estimation of the Erlang distribution was carried out using the Maximum Likelihood method. In maximizing the function, an implicit and non-linear form is obtained, then it is solved using the Newton Raphson algorithm. Apart from Newton Raphon, the estimation of parameters was also carried out using the Fisher Scoring algorithm. The Fisher Scoring algorithm is similar to the Newton Raphson algorithm, the difference is that Fisher Scoring uses an matrix information. The result of parameter estimation in Erlang distribution using Newton Raphson algorithm which is applied to outgoing telephone call data that generated by Matlab R2010a software cannot be done simultaneously. Therefore, the parameter assessment is carried out on the k parameter first, then followed by the λ parameter estimation and the parameter and  = 0.6886812 are obtained. Meanwhile, the parameter estimation using the Fisher Scoring algorithm produces an equation that is not different from the Newton Raphson algorithm
