Impact of hydropower consumption, foreign direct investment and manufacturing performance on CO2 emissions in the ASEAN-4 countries

Purpose The continuous increase in the discharges of carbon emissions (CO2) in the global atmosphere and the likely negative consequences of this practice on the atmosphere draw the attention of researchers and policymakers to argue on the causes and perpetrators of CO2 emissions. This paper aims to examine the impacts of hydropower consumption, FDI and manufacturing performance on CO2 emissions in the Association of southeast Asian nations (ASEAN)-4 countries. Design/methodology/approach The study uses the data on variables, such as hydro-power consumption, FDI, manufacturing value added and CO2 emissions spanning the period 1980–2015. Autoregressive Distributive Lag Bound test approach was used to assess the relationships among the variables. Findings The long run estimation of elasticities for all the countries indicates that the coefficient of hydro power consumption was found to be significantly related to CO2 emissions only in Malaysia. Additionally, the coefficients manufacturing performance were found to be significant in influence the amount of CO2 emission in all the ASEAN-4 countries. Furthermore, the coefficients of FDI inflows were found to be significant in explaining CO2 emissions in Malaysia and the Philippines, respectively. In the short run, the estimated results show that all the variables were found to be significant in explaining CO2 emissions in the countries under study. Research limitations/implications Singapore is excluded from the ASEAN-4 due to insufficient data on hydro energy consumption. Practical implications The study recommends that as Hydro power energy is a clean source of renewable electricity. Its consumption indicates a negative relationship with CO2 emissions. The countries should emphasize more on the use of hydro source of energy than the other sources which increase the rate of CO2 emissions in the atmosphere. Originality/value As most of the relevant previous studies did not consider the simultaneous impact of hydro energy consumption, FDI and manufacturing value added on CO2 emissions in the ASEAN-4, this study is an important contribution to the existing relevant literature.

Integration of Waste Assessment Model and Lean Automation to Improve Process Cycle Efficiency in the Automotive Industry

Purpose: This study aims to improve Process Cycle Efficiency (PCE) by reducing waste in the assembly production line. This research is a case study conducted in a four-wheel vehicle manufacturing company to create a Lean production system. Methodology/Approach: This study uses the Waste Assessment Model (WAM) and Lean Automation integration methods carried out by 5 expert judgements in the selected four-wheeled vehicle industry. Findings: Based on the WAM method, this study found the biggest waste on the assembly line, namely transportation with a percentage of 20.44%. Improvements made with Lean Automation can increase the value of PCE from 56.76% to 63.62%. Research Limitation/Implication: This research is limited to one model, namely Multi Purpose Vehicle (MPV). This research provides benefits for companies related to waste reduction. For similar companies, this research can be input for manufacturing practitioners in improving manufacturing performance to compete in the global market. This Lean production can reduce manpower which has an impact on saving production costs. Originality/Value of paper: This paper provides added value related to the application of Lean terminology which aims to improve industrial automation-based manufacturing companies.

Prospects of Wireless Energy-Aware Sensors for Smart Factories in the Industry 4.0 Era

Advanced sensors are becoming essential for modern factories, as they contribute by gathering comprehensive data about machines, processes, and human-machine interaction. They play an important role in improving manufacturing performance, in-factory logistics, predictive maintenance, supply chains, and digitalization in general. Wireless sensors and wireless sensor networks (WSNs) provide, in this context, significant advantages as they are flexible and easily deployable. They have reduced installation and maintenance costs and contributed by reducing cables and preinstalled infrastructure, leading to improved reliability. WSNs can be retrofitted in machines to provide direct information from inside the processes. Recent developments have revealed exciting possibilities to enhance energy harvesting (EH) and wireless energy transmission, enabling a reliable use of wireless sensors in smart factories. This review provides an overview of the potential of energy aware WSNs for industrial applications and shows relevant techniques for realizing a sustainable energy supply based on energy harvesting and energy transfer. The focus is on high-performance converter solutions and improvement of frequency, bandwidth, hybridization of the converters, and the newest trends towards flexible converters. We report on possibilities to reduce the energy consumption in wireless communication on the node level and on the network level, enabling boosting network efficiency and operability. Based on the existing technologies, energy aware WSNs can nowadays be realized for many applications in smart factories. It can be expected that they will play a great role in the future as an enabler for digitalization in this decisive economic sector.

GUBUK ZISWAF: SOLUSI PEMBIAYAAN HIDUP MASYARAKAT BERBASIS PEMBERDAYAAN LOKAL DI TENGAH PANDEMI COVID-19

The COVID-19 outbreak has the potential to change the economic situation which is marked by a change in the trade map, in addition to causing the cessation of various business fields, global trade performance will certainly be disrupted due to the slow improvement in manufacturing performance. On the other hand, the problem of distributing ZISWAF funds (Zakat, Infaq, Shadaqah and Waqaf) has not been evenly distributed. Therefore, Gubuk ZISWAF is proposed. The purpose of this research is to describe the concept and implementation of Gubuk ZISWAF as a solution for community living financing scheme based on local empowerment during the COVID-19 pandemic. The research method used is qualitative research with literature review approach. The result shows that the implementation technique will be carried out to realize the Gubuk ZISWAF starts from the planning stage, where is related to the formulation of policies by the government and collaboration with related parties, then continued with research and coordination between related parties and the government, development stage, socialization program, and comprehensive implementation (with a ball pick-up system). The results of the implementation of the Gubuk ZISWAF in each of these villages have had a positive impact on the Indonesian economy. In addition to suppressing the rate of poverty in the midst of a pandemic, the possibility of social crimes and the stalling of the economy as well as the spread of COVID-19 can also be prevented.

The Impact of Quality Management Practices on Manufacturing Performance: An Empirical Study Based on System Theory

As one important part of core competitiveness of manufacturing enterprises, quality management practices have gradually received more attention. In many existing researches, quality management practices are regarded as a whole or categorized into two or four types of practice elements for discussions. There are less researches on the relationships among specific quality management practice elements and their impacts on manufacturing performance. This study analyzes quality management practices with the philosophical thinking of system theory, and deconstructs the mechanism of the mutual influences and synergies among various quality management practice elements and also their impacts on manufacturing performance, from an overall perspective through an empirical research. At last, a model of quality management practice synergies is built, as a theoretical support for manufacturing enterprises implementation of quality management practices.
