Abstract

Because information technology has changed so much over time, more and more innovations have been made to make existing technologies more understandable and more up-to-date. for example, in economics, business, entertainment, and other related fields. It is hoped that all members of society can participate in developing science and technology. Almost all types of businesses to date have used a computerized system. The computerized system is made to provide the best service because efforts to increase finances and satisfying services, especially for Small and Medium Enterprises (SMEs) are urgently needed. This business must present a system that can facilitate seller sales and improve customer service because the system used in this sales effort is still manual. As a result, this activity resulted in the creation of a web-based information system that makes it easier for Childs Aquatic Store customers to view product information and make purchases of these products online.

Abstract

Ethanol is one of the chemical liquids that is often used in the world of health as a material for making medicines and sterilization materials, in addition this material has also been used as an alternative energy in all fields. Ethanol production so far comes from petroleum which is decreasing and non-renewable. Ethanol development can come from other materials such as abundant and renewable palm sap and can produce a bioethanol product that can replace commercial ethanol. The aim of this study was to detect the quality of palm sap bioethanol obtained from Mombi village using tempe yeast fermentation. The study used an experimental method with a Complete Random Design pattern with yeast/palm sap concentration variables, namely 2 g/200 mL, 6 g/200 mL, 10 g/200 mL, 14 g/200 mL, and control (without yeast mixture). The parameters observed included pH levels, the amount of bioethanol and the alcohol content of bioethanol. The results showed that there was a decrease in the pH value of the palm sap solution after distillation, where there was an increase in acid in the resulting bioethanol product. The average amount of bioethanol produced reaches 48.86% but the alcohol content in the bioethanol is very low, only reaching 15.46%

Abstract

The requirement for trigona honey is increasing, it is causing various study to be carried out to increase the productivity of bees in producing honey. The use of wood species in the manufacture of trigona stup can be one of the factors that affect the development and productivity of trigona bees. The purpose of this study was to determine the effect of wood species as a stup material on increasing the productivity of Trigona sp. The research was conducted in March-June 2022 in Mirring village, Polewali Mandar district. The stup is made using three types of wood, namely jackfruit wood, sengon wood, and white teak wood. Trigona bees were transferred to each stup, then placed at a distance of 2 meters between the stup. Observations and weighing periodically every 10 days for a period of 80 days. The results showed that the manufacture of stup from the three types of wood had a significant effect on increasing the weight of trigona nests and there was a significant difference in the increase in nest weight of stup made of jackfruit wood compared to sengon wood and white teak wood. The increase in nest weight continued for every observation on the stup made of three types of wood.
