The concept of Penta Helix or Quintuple Helix have been widely discussed and used as frameworks in many researches in relation of innovation or organizational innovation field. it is believed that if the Penta Helix stakeholders work together in synergy it will foster innovation and an innovation-based economy. However, no research has been found yet that validate measurement constructs of the Penta Helix or the Quintuple Helix. Through extensive literature review, we developed a construct of the Penta Helix variables in relation to innovation and knowledge-based economy, into five dimensions consisting of Academicians, Business, Government, Community and Medias (ABGCM). The data was collected through a questionnaire distributed to 95 technology-based startups in Indonesia, and afterward analysed by using confirmatory factor analysis technique, performed by the SmartPLS software. A final 20-item measurement construct was validated as main contribution of this study toward Penta Helix theory. There are issues arose on methodological and theoretical of the Penta Helix construct and discussed in our findings.

Startup companies are expected to become the new engines of economic growth through the rise of new innovation-based entrepreneurs. The Penta Helix framework is widely used as a framework to analyse factors related to the development of innovation-based companies. The use of the Penta Helix framework as the unit of analysis is considered to be relevant because this framework offers a comprehensive perspective and is in line with the economic development innovation and knowledge-based startups. However, there is a lack of research that has been conducted that analyse the nature of support that can be given to startups at their early-stage of creation using the Penta Helix framework that consists of five stakeholders namely Academicians, Businessmen, Government, Communities. This study aims to propose a conceptual model about the nature of support needed by startups in order to survive in their initial stages by using the Penta Helix Framework. This study is a qualitative one using the Focus Group Discussion method, in which participants are made of six early stages technology-based startup founders and CEOs, who were gathered to conduct several discussions regarding the topics. Our results show that obstacles faced by startups include among other: difficulties in obtaining qualified yet affordable workforce in facing existing competitors, difficulties in increasing sales, difficulties in managing product development costs, no adequate support from the government, and ineffective incubation programs. A model that consists of lists of support that startups need, was depict as main contribution from the discussion, named Penta Helix support for startups. This model offers comprehensive practical guide for policy makers to support startups from five perspectives.

An optimization model of allocation of zakat fund and recipients is developed based on the Data Envelopment Analysis - Resource Allocation Model (DEA-RAM). The quantitative method plays an important role in optimal allocation of zakat delivery programs performed by some zakat institutions; that is by reallocation of initial setting of the zakat fund and beneficiaries numbers. It raises the needs of improvements in their recent strategies on the programs by the institutions. Zakat institutions, even the government as regulator, should have a clear focus on the poverty-empowerment-based programs in providing needed capitals for poverty empowerment. They are expected to create certain conditions in order to prevent excessive of fund allocation for the charity-based delivery programs.

Shari'ah-Compliant E-Commerce Models and Consumer Trust. This study is aimed at finding out the real picture of Shari'ah-compliant E-commerce model and consumer trust in e-commerce today, analyzing its drawbacks, and finding out how they influence each other. Shari'ah-compliant E-commerce model is a model that describes how e-commerce should run in accordance with the provisions of the Shari'ah. Broadly speaking, e-commerce in the perspective of Shari'ah must comply with some rules, namely: 1. the form of the offer and transaction agreement; 2. the transacting parties (buyers and sellers); 3. Objects and prices in the transaction; 4. Free from major prohibitions in transactions. The sample in this study is Indonesian citizen who are consumers of e-commerce. This research uses descriptive and statistical methods with multiple linear regression model. This model is considered relevant and good to be studied in order to enlighten how e-commerce is currently in the perspective of Islam.

Zakat is part of the five pillars of Islam, which is legally obligatory to do when one's property has touched the nishab and haul. Zakat has considerable potential to overcome economic problems, especially poverty. DKI Jakarta is the sixth largest city in Indonesia, with a majority Muslim population. So DKI Jakarta also has considerable zakat potential. However, there is a difference between the potential amount of zakat receipts in DKI Jakarta and the realization of zakat fund collection. This research aims to see the effect of religiosity, income, transparency, and service quality on the decision-making of muzakki to pay zakat in Baitulmaal Muamalat (a case study in DKI Jakarta). This research is the descriptive quantitative approach with multiple linear analysis methods. The sampling technique chosen in this research is probability sampling, Simple random sampling. The sample from this study amounted to 217 muzakki in DKI Jakarta, who distributed their zakat in Baitulmaal Muamalat. The analysis results show how the variables of religiosity, income, transparency, and service quality partially or simultaneously impact the decision-making of muzakki to pay zakat through baitulmaal muamalat in DKI Jakarta.
