Hanguana Malayana, known as Bakong plant is an invasive macrophytic plant found in few regions of the Philippines. Due to its mode of propagation, it occupies large spaces and it invades the space that’s allotted for the crops of local farmers. Hence, the researchers investigate this plant for beneficial uses. In this study, the effect of the different concentrations of H. malayana crude ethanolic leaf extract on Saureus is evaluated on the basis of the study of Ooh and company (2014) stating that the plant is a potential resources of bioactive phytoconstituents. This research concluded that the Hanguana malayana crude leaf ethanolic extract has an antibacterial property against Staphylococcus aureus.

Implementation Of Solar Cell Based Smart Chair As A Green Open Space Electric Energy Source

Wed, 20 Jan 2021 00:00:00 +0700

This research aims to propose new solutions for alternative sources of electrical energy in open spaces. We validated this solution by implementing a solar cell in a park bench object. Furthermore, analyzing the statistical data by taking the average value of; current, voltage, and power generated by the smart bench object. The experimental results show that the proposed solution has the same performance as conventional lighting. Electric park benches can operate longer using a solar cell with an output power of 26.76 Watt-peak hours. With the large potential of solar power, solar cells' application in an open environment is very suitable. With this electric bench, it is still energy efficient and green energy

Renewable Energy Alternatives: Bioetanol in Cassava as an Energy

Okocha Michele — Wed, 20 Jan 2021 00:00:00 +0700

The study aimed at investigating the use of cassava as potential alternative renewable energy. The study method utilized is a descriptive method of making bioethanol from cassava on a research facility scale. 50 kg of new cassava, include 1.5 ml of alpha-amylase protein at that point warm for 30-60 minutes Include 1 g of bread yeast, 65 g of urea, and 14 g of NPK. The efficiency of cassava at the cultivate level is 14.3 - 18.8 to/ha, in spite of the fact that information from the inquire about center reports that efficiency can reach 30-40 tons / ha. It is prescribed that cassava as a biofuel fabric comes from assortments that have the taking after properties: tall starch substance, tall abdicate potential, safe to biotic and abiotic stresses, adaptability in cultivating and collecting age.

Comparative Analysis of the C4.5 Algorithm and the Nearest Neighbor for the Number of Prospective New Student Registrants

Nursetia Wati, Irawan Ibrahim — Mon, 22 Feb 2021 00:00:00 +0700

In 2015, the number of registrants for new student candidates at Muhammadiyah University of Gorontalo, has increased about 20% - 50% from the last year in 2014, but when it starts from 2017/2018 of the academic year the number of new student candidates who registered was only around 4,713 students for bachelor’s and there is 1,256 students for Bachelor’s Degree, while in the academic year of 2018/2019 bachelor’s degree students were only 765 and bachelor’s students were around 4,187, it is known as a decline from the previous year. This study, aims to help to predict the number of prospective of the new students who will enroll in the following of the academic year by analyzing the comparison of the C4.5 and Nearest Neighbor Algorithms with comparing two of algorithms to get the best results. In the C4.5 and Nearest Neighbor Algorithms, it is necessary to be able to see some patterns from the data about the prospective students, then, they can produce the predictions of the number of prospective students who can help in increasing the number of prospective students that is according to the target achievements of Muhammadiyah University of Gorontalo (UMG) itself.

Biomass from Palm Oil Waste as a Renewable Energy Source with Community Benefits

Schafir Thomas, Andres — Thu, 15 Apr 2021 00:00:00 +0700

This article addresses Biomass as a green energy source. The oil palm by-product is commonly accepted as a suitable raw material for power plant diesel. Numerous countries are beginning to transition to palm biomass as a fuel source due to its environmental friendliness and green nature. Renewable energy management needs technology, since it would only be produced to generate energy from natural products that will never run out. Nevertheless, the life of the oil palm plantation itself is very poor. For example, the influence of oil palm plantations on natural capital in green land has decreased or even vanished. Indeed, the biological organisms that inhabit it are the primary source of life for the population, especially the indigenous people who live in close proximity to the soil.

Mangrove Ecosystem, Seagrass, Coral Reef: its Role in Self-Purification and Carrying Capacity in Coastal Areas

Hasim Hasim — Thu, 15 Apr 2021 00:00:00 +0700

The coast is an area that has very high activity. It is estimated that 60% of the world's population lives in coastal areas. Various types of pollution enter this area. Halogenated hydrocarbons, pesticides, marine biotoxins, synthetic fertilizers, livestock and fishery waste, heavy metals, hot water discharges and radioactive substances. Coastal areas are natural ecosystems built by unique ecosystems including mangrove forests, seagrass beds and coral reefs. The three ecosystems interact dynamically and are interdependent. One of the characteristics of natural ecosystems is the ability to self-purify so that their carrying capacity is optimal. The coastal self-purification capacity is built by the synergy between the physical, chemical and biological components as well as their hydrological-morphological components. The self-purification mechanism includes filtration, transformation, degradation and decomposition. Self-purification is the ability of coastal ecosystems to accept a certain amount of waste in a complex natural process and before there is an indication of a decrease in its intended function. The implementation of self-purification effectively will support the optimization of carrying capacity, namely the ability of the ecosystem to support the life of the population. There are three factors related to carrying capacity, namely the availability of natural resources, population and consumption levels.
