Crude oil and palm oil had a positive relationship before pandemic and during the pandemic coal and the exchange rate had a positive relationship. Meanwhile, after the COVID-19 pandemic, no covolatility spillover was found. An increase in covolatility spillover from exchange rate asset pairs was found during the pandemic. This research also shows the potential for portfolio diversification for each asset pair through optimal portfolio weights. Understanding volatility movements and interdependencies in commodity futures, stock markets, and exchange rates is important for proper investment management, and this research can help investors make appropriate decisions.

Abstract

The bottled drinking water (air minum dalam kemasan, AMDK) industry in Indonesia faces increasingly intense competition due to the rapid growth in the number of producers and registered brands. This situation prompts PT Harazaki Surya Abadi, the producer of Lavida bottled water, to strengthen its competitiveness by improving its distribution channels. This study aims to analyze and implement value chain management in strengthening distribution channels: a business coaching study at the Lavida Depot Jakarta in the development of the Lavida Jakarta Depot as a strategy to expand distribution coverage and enhance sales performance. The research adopts a business coaching approach, with data collected through interviews, direct observation, and document analysis. The analytical framework includes the Business Model Canvas, Porter’s Five Forces, SWOT analysis, and VRIO framework to identify key problems and strategic needs. The findings indicate that limited distribution reach is the main barrier to Lavida’s market growth. The implementation of value chain management is realized through the design of business processes, development of standard operating procedures, marketing and sales planning, and strengthening of procurement and logistics systems. The results demonstrate that a value chain–based approach improves the operational readiness of the depot in supporting effective and efficient distribution channel strengthening.

Abstract

Biomass utilization is believed to bring environmental and socio-economic benefits—PT X coal in a steam boiler. The research method used is a mix of quantitative and qualitative. The concentration of particulates that coal produces is higher than that of sugar cane bagasse. The NOx parameter values produced by bagasse and coal showed insignificant results. Meanwhile, coal boilers with higher temperatures produced higher NOx than NOx from biomass. The distribution concentration of SOx in bagasse biomass is higher than coal SOx emissions. A total of 26 communities agreed to change the use of coal to bagasse biomass. Utilization of bagasse biomass provides income of up to 94,000,000,000. Using bagasse as steam boiler fuel has a more positive impact than coal.
