Entrepreneurial Ecosystem Dynamics in Emerging Economies: A Systematic Literature Review of Innovation, Institutional Gaps, and Digitalization
Full text linkThe entrepreneurial ecosystem is a crucial framework for understanding how the interplay of innovation, institutions, and digitalization drives economic growth, especially in emerging economies. However, many developing countries still face structural challenges such as limited access to financing, weak regulatory capacity, and technological gaps that hinder the dynamics of the entrepreneurial ecosystem. These conditions create institutional gaps that impact innovative capabilities and the digital transformation process of entrepreneurship. This study aims to conduct a Systematic Literature Review of various recent empirical and conceptual studies to analyze how innovation, institutional gaps, and digitalization interact in shaping the competitiveness, resilience, and sustainability of the entrepreneurial ecosystem in developing countries. The study\u27s results indicate that the dynamics of the entrepreneurial ecosystem in developing countries are significantly influenced by the strong interactions among innovation, institutions, and digitization. Innovation, especially green and digital innovation, acts as the main driver of value creation and entrepreneurial competitiveness. Institutions serve as the foundation of governance, but still face obstacles in the form of bureaucratic rigidity and policy fragmentation. Meanwhile, digitalization acts as an integrative catalyst that bridges institutional weaknesses, accelerates the flow of information, and strengthens cross-sector collaboration

Analisis Cacat Produk Dimensi Diameter Snap Tidak Standar pada Botol 100 ml Berbahan Dasar High-Density Polyethylene (HDPE)
Full text linkExtrusion blow molding is a process used to form plastic bottles, with High-Density Polyethylene (HDPE) being the most commonly used material. A defect in the snap diameter that did not meet the standard was identified during the production of 100 ml bottles at PT X Jakarta, potentially reducing product quality and affecting its functionality. This study aims to identify the root causes of this defect and propose corrective actions and improvements to enhance product quality. The methodology includes using a Fishbone Diagram to determine the root causes, applying the 5W+1H analysis to develop corrective action proposals, and implementing the Poka-Yoke method as an improvement strategy. The findings indicate that the defects are caused by three main factors: human, method, and machine. Human-related factors include a lack of operator understanding of quality standards, insufficient training, and a limited number of technicians. Method-related factors involve inadequate maintenance and improper bottle handling, while machine-related factors include mold dimension changes, dirty die heads, and the need for machining parameter adjustments. The proposed corrective actions for human factors involve regular training, the provision of Standard Operating Procedures (SOPs), visual guidelines, and additional technicians. Machine-related improvements include periodic inspections, die head cleaning, and machining parameter testing, while method-related improvements focus on scheduled preventive maintenance and proper bottle runner arrangement. Further improvements involve implementing the Poka-Yoke method by installing an alarm siren that activates when air compressor pressure falls below the standard and adding markings to help operators better understand machine parameters during production

Using a normative legal approach, the research analyzes positive law and mediation practices both inside and outside the courts. Legal reform is needed, including the enactment of a Mediation Law, strengthening of mediator institutions, and online mediation regulation to meet modern demands
The Existence of Islamic Law in The Legal System And Constitution in Indonesia: Reflection of Islamic Legal Thought and Positive Law
Full text linkThe legal position of Islam in the Republic of Indonesia cannot be separated from the influence of the entry of Islam throughout the archipelago around 16-17 Hijri, where at that time the spreaders of Islam throughout the archipelago came from various Middle Eastern countries, such as India, Pakistan, Arabia, Egypt, Jordan, and others, they traded to the archipelago while spreading Islam, and on average they brought the Shafi\u27i school of thought. The historical journey of the transformation of Islamic Law with various dimensions, namely; historical, philosophical, political, sociological, and legal. The presence of Islamic Law in Indonesia can be seen from two sides, namely: Islamic law applies legally formally or codified in the National legal structure, so the current compilation of Islamic Law was born which recorded the regulations of Islamic Law that have been enforced so far. And Islamic Law applies normatively, namely; having sanctions or legal equivalents for the Muslim community. The 1945 Constitution, Indonesia\u27s constitution, also expresses the character and spirit of Islam, a constitution that is neither theocratic nor secular
K-Pop sebagai Mekanisme Regulasi Emosi pada Remaja
Full text linkThe K-Pop phenomenon has become an important part of the lives of adolescents in various countries, including Indonesia. Music, concerts, and fandom activities not only serve as entertainment but can also be interpreted as one form of emotional regulation mechanism. This study aims to systematically review the role of K-Pop in supporting adolescent mental health, particularly through the Process Model of Emotion Regulation framework developed by Gross. The study found that adolescents\u27 involvement in K-Pop is closely related to five emotion regulation strategies: situation selection, situation modification, attention deployment, cognitive change, and response modulation. Activities such as listening to K-Pop music, attending concerts, watching online contents, and interacting within fandom communities have been shown to help adolescents divert their attention from stress, build cognitive reinterpretations of negative experiences, and channel emotions adaptively. K-Pop can serve as a significant tool in supporting adolescent mental health, though parental guidance, educator support, and a balanced social environment remain essential to ensure its use is balanced
