Abstract

A life cycle assessment (LCA) has been performed on sorbitol production from glucose, which aims to quantify and evaluate the environmental impacts that produced from the process. SuperPro Designer software was employed to perform the process simulation, while SimaPro was used to quantify the LCA.Potency of global warming, acidification, eutrophication, photochemical oxidants creation, abiotic depletion, and ozone layer depletion were evaluated. A gate-to-gate LCA study of sorbitol production showed that global warming potential (GWP) had the largest impact to environment with the value of 3.551 kg CO2 eq/kg sorbitol. Glucose and electricity consumption were known as two major contributors to GWP, and hydrogen reactor was the main consumer of electricity. The use of glucose were responsible for more than 50% of total environmentalimpact in each category. Performing heat integration in sorbitol processing is highly recommended for gate-togate system to reduce energy demand, thus decreasing the environmental impacts. Therefore, this LCA study may be applied to perform a sustainable improvement on sorbitol production process.Keywords: sorbitol; life cycle assessment; global warming potential

Abstract

The demand of drinking water is growing continuously, so that the business prospects are also increasingly promising. This condition becomes a challenge for business doer of drinking water, including CV. Tirta Sasmita. A manual customer data management in CV. Tirta Sasmita causing most of customer data are not well documented, so that it may reduce the number of customers. Customer relationship management (CRM) that consists of human resources, process, and technology is a strategy which can be implemented to improve the customer service to be more effective. This research aims to design a CRM-based application that can be used in marketing control system for business doer of drinking water CV. Tirta Sasmita. This research used qualitative approach method, with descriptive research to arrange a business process flow, and action research to design CRM application using Unified Modelling Language (UML) and interface design. This application was developed using prototype method, in which customer database inside are beneficial to ease the remarketing activity. ‘Add order’ menu in CRM application system is also beneficial in terms of sales trends. There are seven access rights in the application which are based on business process flow of CV. Tirta Sasmita, namely sales counter, field sales, supervisor marketing, manager marketing, finance, surveyor, and legal. This system can be implemented based on process business in CV. Tirta Sasmita.

Abstract

The use of chemical pesticides to control grasshopper attacks harms the environment and people. Therefore, botanical pesticide as an alternative to a safer environment is needed. This study aims to determine the effectiveness of papaya leaves (Carica papaya) and lemongrass (Cymbopogon citratus) combination extracts against Javanese grasshopper based on maceration time and concentration variations, and to determine its compounds. The maceration time was 3, 5, and 7 days, and 30, 50, and 70% concentrations were used. The study showed that a 7 days maceration with 70% extract concentrations is the most effective to kill the Javanese grasshopper with an average mortality rate of 100%. Botanical pesticides are known to contain tannins, flavonoids, terpenoids, steroids, and citronellal. The presence of these compounds in the botanical pesticides causes Javanese grasshoppers which eat plants that have been sprayed to experience death due to poisoning and continuous loss of fluid.
