Abstract

Tarakanita Gading Serpong Senior High School aims to be an educational institution as well as a research center that adheres to the concept of education for sustainable development. Therefore, the staff of Tarakanita Gading Serpong High School wanted a teaching module that could serve as a learning tool for students, as well as a research instrument for the staff to study the use of renewable energy sources in the form of solar power. To meet their needs, a prototype of a small solar module that can simulate how a solar panel works and measure its output voltage, current, and electrical power was designed and built. The module is equipped with a 50 Wp polycrystalline solar panel, a solar charge controller to regulate the distribution of electric current, an 18 Ah battery to store energy, and an electrical load in the form of an 18-Watt light bulb.  The solar module is designed to be easily moved and operated indoors or outdoors. When the module is indoors, a 75 W Halogen UV lamp is used as a proxy for sunlight. Hopefully, this solar module can serve as an effective learning medium to introduce the use of solar power as a renewable energy source for Tarakanita Gading Serpong High School students.

Abstract

Compared to traditional lignocellulose biomass, microalgae contain little or no lignin. Traditionally, bioethanol production from microalgae undergoes three major steps: (i) pretreatment; (ii) polysaccharides hydrolysis into simple sugars; and (iii) sugar conversion into bioethanol by fermentation. Microalgae convert sunlight, water, and CO2 into algal biomass. Diatoms, green algae, bluegreen algae, and golden algae are four main classes of microalgae, whereas the two main species of algae are filamentous and phytoplankton algae. Microalgae convert solar energy efficiently, producing an enormous number of various metabolites. Many studies have been conducted to convert microalgae into various biofuels, such as biodiesel, bioethanol, biohydrogen, and biogas. However, compared to biodiesel, bioethanol production from algae throughfermentation consumes less energy with its simplified process. Considering these advantages, a number of potential applications for microalgae have been proposed and developed. Despite the promising of bioethanol from microalgae, it still has a number of obstacles, such as the low fermentable carbohydrate content of microalgae. This article intends to discuss the methods to increase microalgae carbohydrates thoroughly. To solve this problem, several nutritional starvations/limitations, like nitrogen and phosphorous starvation, are currently being considered in this paper.
