Synthesis and Characterization of Biodegradable Blend based on LDPE/cassava stem nanofiber cellulose
Get PDFConventional plastic becomes trend topic due to its long degradation time and needs attention related to environmental problem. One type of plastic that is difficult to be degraded is LDPE. Some of the efforts done is to synthesize plastics with organic material so that it becomes biodegradable plastic. Cellulose is an organic material that is abundant in nature and can be used as a filler. This research aims to synthesis the biodegradable plastic films composted by nanocellulose – LDPE. Mechanical (UTM), water resistance and degradation test has been done. The properties of the biodegradable blend still meet the commercial LDPE standart. Even though the biocomposite based on LDPE-nanofiber cellulose can not totally degradable but it is can be used as a solution to reduce the degradation time of a plastic waste
THE PERFORMANCE MEASUREMENT OF CONSULTING SERVICE COMPANY IN INDONESIA; CASE STUDY
Get PDFPerformance evaluation is the first step of a company in reaching its competitive advantage in the midst of globalization and free market enactment.

ANALYSIS OF ZERO PLASTIC BAG POLICY EFFECT ON GREEN BEHAVIOUR WITH STRUCTURAL EQUATION MODELING (SEM) METHOD
Get PDFPlastic bag is a product that is very often used in everyday life. Plastic bags are one of the biggest contributors to the volume of waste in Indonesia. Therefore, a policy related to the use of plastic bags is called a zero plastic bag. This policy requires plastic bag users to switch to using environmentally friendly bags. This study was conducted to analyze the effect of the zero platic bag policy on Makassar City community behavior related to the environment or green behavior if this policy is applied in the City of Makassar. To determine the effect of the zero plastic bag policy on people's behavior patterns about the environment using the SEM (Structural Equation Modeling) method. Initial identification was carried out by distributing questionnaires to respondents using plastic bags, especially retail consumers in Makassar City. The questionnaire contained green behavior variables which consisted of five variables. Then the results of data collection using a questionnaire are processed using descriptive analysis and then look for the effect of zero plastic bag policies on green behavior using the SEM method. The results of the identification of the influence of zero plastic bag policy based on four variables namely environmental knowledge, environmental attitude, green advertising, and green consumption on green behavior are that of the four variables that have a positive influence on green behavior are environmental attitude, green advertising, and green consumption . The results of this study can be used as policy input and see how effective this policy is when applied in Makassar City
DESIGN AND SIMULATION OF COCONUT TREE CLIMBING TOOL FOR COCONUT FARMERS IN LOMBOK SANGATTA BAY, EAST KUTAI
Get PDFGreat potentiality of coconut cannot be separated from the method of coconut harvest which still draw a lot of problems in. Until now, coconut farmers still use climber service in coconut harvesting. The process of coconut tree climbing is usually done without tools. This is very risky for the harvesters. Since the utilization of animal service (monkeys) have already prohibited from commercial activities, human service in coconut tree climbing becomes the alternative for the farmers. For this reason, the aim of this study is to design a tool for coconut tree climbing that will help coconut harvesters in Lombok Sangatta Bay, East Kutai, by considering climber's characteristics. Furthermore, the tool is made in form of design, which then being simulated to determine the tools’ safety level, stress level and the ability which is designed by using SolidWorks 2018 software.The result for the proposed design of coconut tree climbing tool for coconut harvester in Lombok Sangatta Bay, East Kutai, is to use 20 mm x 20 mm x 2 mm of hollow profile with AISI 1020 material built, which is declared safe for 80 kg capacity. The highest score of stress is 223.04 Mpa on body holder, 4.68 mm deflection, 1.6 in factor of safety, and 17.08 kg for tool's overall weigh
