Abstract

An organization/company cannot be separated from decision-making. Intuitive decision-making is highly discouraged if it is not from a reliable source because the level of deviation that occurs can be very large. Therefore, we need a reliable basis for making a decision. The D'Amerta Berniaga business group does not use online media to carry out its business. This has resulted in the underdevelopment of the business being carried out, given the increasingly fierce business competition at this time. However, the decision to use online media is very difficult considering that business owners are housewives and sole implementers in their businesses. This resulted in an increase in workload and a very large amount of time to use online media, causing doubts about the decisions to be taken. Therefore, training on the use of online media was carried out in an effort to overcome this problem. The existence of training makes business owners interested in using online media. The business owner's decision to use online media needs to be evaluated to determine the accuracy of the decisions taken. This study aims to see whether the decisions taken by business owners, namely using online media, are appropriate and able to contribute to their business. The method used is a quantitative method with a descriptive approach. Measurements were made based on the total population of 30 respondents by pretest-posttest. Based on the test results with the paired t-test, it can be seen that the decisions taken, namely using online media, have a significant influence on existing businesses.

Abstract

Petroleum reserves in Indonesia are running low, as well as fossil energy. If these conditions are not handled appropriately and quickly, the Indonesian nation will experience a petroleum crisis. Biomass briquettes are made from a combination of rice husks, taro husks, and a tapioca flour adhesive, and they will be produced as a byproduct of Indonesia's extensive agricultural sector and the growing taro industry. The use of taro skin in conjunction with other raw materials gives this study an element of originality. The purpose of this research is twofold: to disseminate knowledge about the potential of biomass waste, and to analyze how different biomass waste mixtures affect the briquettes SNI-required properties. An experimental approach was used for this study. In this experiment, three different weight ratios of taro husks to rice husks (KT:50%, KT:75%, and KT:100%) were employed as the primary raw materials. Five-and-a-half percent of the briquette dough's overall weight comes from tapioca flour's role as an adhesive. Preparation of briquette materials, carbonization, briquetting, and testing for biomass briquette characteristics are the first steps in the study approach. The calorific value, moisture, ash, volatile matter, binding carbon, and density tests are all part of this battery of analyses. The highest grade briquettes have a calorific value of 3,993.92 cal/g and are made from 100% KT briquettes. KT briquettes with a 75% moisture content are the highest grade briquettes available. At 22.90%, KT briquettes have the lowest ash level of any high-quality briquettes. Briquettes made from 100 percent KT, or 0.09 percent volatile matter, are the highest grade available. KT briquettes, which have a bonded carbon content of 74.59%, are the highest grade option. 50% KT briquettes, with a density of 0.48 g/cm3, are the highest grade briquettes available.
