This study aims to formulate a suggestion in the form of a business model to be actualized in Indonesia based on the distinguishing proof of benchmarking from South Korea within the setting of social enterprises and their comparison to actual external factors in Indonesia. The descriptive analysis from the comparative study of external factors and business models was carried out using PESTLE analysis tools (Politics, Economics, Social, Technology, Legal, Environment) and business model typology (Alter 2017). The results generates two business model recommendation, those are Independent Social Movement Business Model of Social Enterprises and Integrated – External Mixed Business Model of Social Enterprise.

Judul: Perkembangan Terkini dari Inovasi Model Bisnis Berkelanjutan: Tinjauan Literatur Sistematis
Abstrak: The digital transformation in the fourth industrial revolution (Industry 4.0) disrupts the entire industry system and forces the industry to innovate by shifting the traditional business model to business model innovation that enables sustainable development. However, research suggests that business progress of sustainable business model innovation; the subsets of business model innovation, is lagging behind. Despite the growth of literature on the topic, the bridges between conceptualization and implementation are relatively unexplored. This study provides a comprehensive review of sustainable business model innovation through a systematic literature review. Its key contributions are: (1) a review of the development of the concept by pointing out the evolution of definitions, also key components, and frameworks or tools identification; (2) a factor identification through barriers and drivers; and (3) an acknowledgment of the roles of sustainable business model innovation in the implementation of sustainable business model., Transformasi digital pada era revolusi industri 4.0 mendisrupsi seluruh sistem industri dan memaksa industri untuk berinovasi dengan mengalihkan model bisnis tradisional ke inovasi model bisnis yang memungkinkan perkembangan berkelanjutan.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
