The Effect of Technology and Company Characteristics on Firm’s Survival: Case Study of Indonesian Manufacturing Industry
Facing globalization and industrial revolution 4.0 requires companies to continue innovation to maintain their existences. Innovation can be carried out well if the company can absorb and apply the latest technology to increase the efficiency of its business. Firms that are unable to adapt to technology will not be able to compete with their counterparts. Therefore, this research was conducted to see the effect of technology, the firm's characteristics (size and location), and productivity (productivity and company profit) on the firm's survival. Using logistic regression, this study shows that technology, the firm's size, and productivity have a significant positive effect on the firm's survival. The location has a significant negative impact on the firm's survival, and profit does not significantly affect the firm's survival. The Hosmer and Lemeshow Test show that the model used in this study is fit for estimating all variables
Dampak Spillover Penanaman Modal Asing terhadap Produktivitas Industri Manufaktur Medium-High Technology di Indonesia
This study examines the impact of foreign presence in the Medium-High and High technology manufacturing industry in Indonesia. Using a balanced panel data that consists of 2,397 firms and in the year of 2010-2014, the data was estimated using the multiple regression method. The results show that there is positive spillover when local and foreign firms are in the same industry. Conversely, in different industries, negative spillover occurs in forward linkage when local firms buy the output of foreign firms and no spillover occurs in backward linkage when local firms become the suppliers of foreign firms. The Indonesian government must assure that foreign investment policies must benefit the domestic companies, considering there are some potential losses for domestic enterprises by the presence of foreign direct investment in the domestic market

ENERGY EFFICIENCY OF INDONESIA’S SUGAR INDUSTRY BASED ON ECONOMIC FRAMEWORK: STOCHASTIC METAFRONTIER ANALYSIS
This study investigates the efficiency of energy use and technology gap in the Indonesian sugar industry and the factors influencing energy efficiency. Using the firm-level data of sugar mills in 42 regencies in Indonesia from 2010 to 2014, this study applies the meta stochastic frontier based on the input distance function. The metafrontier analysis is applied in sugar mills in the East Java province and other provinces in Indonesia. All the data used in this study are the secondary data taken from the Indonesian Central Board of Statistics. The results reveal that there is a large room to save energy consumption in this industry. The mills in East Java provinces have higher energy efficiency, technology gap ratio, and metafrontier energy efficiency compared to the mills in other provinces. According to the metafrontier energy efficiency, energy inefficiencies in both groups come from operational inefficiency and technology gap. The size of the mills and age of the mills have a positive relationship with the energy efficiency of sugar mills and the size of the mills is positively related to the technology gap ratio. Meanwhile, the productivity of labor and the types of ownership do not affect the energy efficiency and technology gap

The results of partial regression test AAB affect inefficiency, TPM and TTU do not affect. Meanwhile, simultaneously AAB, TPM and TTU affect the inefficiency of health services. So that it can increase the improvement of AAB access to reduce inefficiency
The spillover effects of foreign direct investment on the productivity and efficiency in Indonesian manufacturing industry
The study aims to examine foreign direct investment spillover effects on the firms’ productivity performances
and to examine the most important component of total factor productivity growth in explaining output growth. This study employs a time-varying stochastic frontier approach for firm level panel data of Indonesian manufacturing industry and performs a non-parametric test of the closeness of two distributions. The results demonstrate that foreign firms achieve higher productivity but less efficient than domestic firms. Increasing degrees of foreign ownership is negatively related to firms’ productivity but positively related to firms’ efficiency. There are positive horizontal spillover effects of foreign direct investment on the firms’ productivity and efficiency. The backward spillovers have positive impact on firm’s efficiency, and the forward spillovers have positive impact on firm’s productivity. However, there are negative backward spillover effects on firms’ productivity and negative forward spillover effects on firms’ efficiency. Besides that, within the same market technology spillover from FDI are smaller with higher level of labour quality. In the upstream market, the degree of absorptive capacity of suppliers has a negative impact on firms’ productivity but have a positive impact on reducing inefficiency. In the downstream markets, the greater ability of the buyers to identify, assimilate and exploit knowledge spillovers, the greater the impact on increasing productivity but the lesser the impact on reducing inefficiency. Finally, this study finds that all components of productivity; technological progress, technical efficiency change and scale efficiency change significantly contribute in explaining the TFP growth
Efficiency of Land Use in Smallholder Palm Oil Plantations in Indonesia: A Stochastic Frontier Approach
Indonesia has become the country with the largest palm oil production. However, the level of productivity of oil palm per land in Indonesia tends to remain stagnant. The main objective of this study is to evaluate oil palm lands of smallholders that experience land inefficiency. In analyzing land efficiency, this study used cross-section data obtained from Statistics Indonesia (BPS). This study uses an input distance function approach with stochastic frontier analysis tools. Our estimation results found that on average, smallholders oil palm plantations face land inefficiency. The land inefficiency of smallholder oil palm plantations is not proportional to the negative impacts it has caused. The intensification of oil palm plantation land is one of the ways to reduce the rate of deforestation and optimize available land. Land intensification can be done through the selection of potential lands, renewal programs for oil palm trees, supporting facilities and infrastructure, and plantation technology development
