Abstract

The economically feasible study has become an important factor in today's societies due to achieve the well-being of people. The study analyzed the economic perspective of biomass energy from several secondary data locally and globally. The main target of this study aims to explore the economic perspective of biomass energy in Indonesia. The purpose of this study evaluates from many several economic advantages of the utilization of biomass energy such as economic sustainability, and job creation, and the last one is achieving sustainable development goals. Intensive exposure to several analysis factors of the advantages of modern biomass energy that is leading to economically feasible sustainability for the environment and local people in Indonesia. Moreover, it was found that the relationship between biomass energy and sustainable development significantly related to and supported the achievement of United Nation – Sustainable Development Goals (UN SDGs). Based on analyzing the biomass energy and economic strong effect on social development. After this, found significant benefits of biomass energy by creating local income, health care, school, and transportation as well as agriculture. These conclusions are discussed from many literature predictions about the future perspective of the relationship between biomass energy and economics. Recommendations encourage to government, investors, and stakeholders to involve biomass energy which is aim to achieve renewable energy targets. This research will provide more understanding of the several benefits of biomass energy and also to policymakers and investors to the intention of economic growth of biomass energy.

Abstract

Cleanliness has become an integral element of daily living. Soap is often used as a cleaning agent. Soap can remove grime and microorganisms that adhere to the skin. Various types of fats or oils are often utilized as soap's primary constituents. The usage of these diverse oils alters the properties of soap, beginning with its hardness, its impact on the skin, and the resultant foam. 3 grams and 5 grams of Spirulina are added to the soap formulation. The pH test, foam height test, and organoleptic test are the test parameters. The findings demonstrated that the pH of each solid soap preparation was nine, which was in agreement with national standard criteria. The foam stability formed was 75% and 25%, and that the soap formulation maintained its color, shape, and odor for a period of ten days during storage. This research concludes that Spirulina platensis can be made into a solid soap formulation. The effects of the addition of Spirulina to solid soap include a light green color, a solid shape or solid texture, and a distinct perfume of essential tea tree oil, as well as the production of quite a bit of foam and a little coarseness.

Abstract

The aim of this study is to determine the effect of neem leaves in preserving the mineral elements content of two tomato types from Sokoto state, Nigeria. Healthy, ripe and firm tomato fruits brought from Sokoto City, were selected, cleaned for this study. 5%, 10% and 25% by were prepared by dissolving respective 5g, 10g and 25g neem extracts in 9.5, 9.0 and 7.5 liters of distilled water respectively to preserve tomatoes. The experiment was laid in a completely randomized design. And elements, Na, K, Ca, Mg, and P were determined in the tomatoes after the experiment using atomic absorption spectroscopy. The levels of Na, K, Ca, and P in Daneka after preservation ranges are: 1.1-1.3(ppm), 2.1-2.3 (ppm), 1.0-1.3 (ppm), 0.30-0.34 (ppm), and 0.3200-0.3330 (ppm) respectively. The levels of Na, K, Ca, and P in UTC after preservation ranges are: 1.6-1.10 (ppm), 1.6-1.10 (ppm), 0.10-1.16 (ppm), 0.30-0.35 (ppm), and 0.9997-1.0998 (ppm) respectively; revealing an increasing trend of elemental contents of all the tomato cultivars with an increasing neem concentration. Thus, the neem leaves indicate the capacity to preserve a typical quality parameter of tomatoes, that is concentration of Na, K, Ca, and P elements at p < 0.05 significant level.

Abstract

Smaller size plastics known as microplastics are harmful for marine biota as well as humans. One of the common methods for the removal of microplastics from water is coagulation. Chicken eggshells and chitosan are two natural ingredients which contain useful content for the coagulation process. Therefore, this paper describes the effect of concentration of eggshells and chitosan as coagulants in the separation of microplastic from water using RSM (Response Surface Methodology). The effect of tannic acid concentration as coagulation aid was also analyzed in this paper. The coagulants were varied with concentration of 1.5-8.5 g/100 mL and tannic acid concentration was 3-17 mg/100 mL. The result of this study showed coagulation with the highest efficiency occurred when 8.5 g/100 mL of chicken eggshell coagulant (89.14%) and 10 g/100 mL chitosan coagulant (75.67%) was added. Optimum operation occurred after the addition of coagulant aid in the amount of 7 mg/100 mL with chicken eggshell and 15 mg/100 mL with chitosan.

Abstract

The study focuses on malnutrition. Dietary intake influences malnutrition. Indonesians choose dry noodles due of their portability. Dry noodles often include more carbohydrates than protein; consequently, the addition of Spirulina platensis may increase their protein level while de-creasing their carbohydrate load. This research evaluated the levels of protein, fat, water, and ash in dry noodles before and after supplementation with spirulina platensis. 1% and 2% of the fixed variable weight of Spirulina platensis were used. Included in analyses are protein, fat, water, and ash. Variation I (1%) results protein of 15.79%, whereas Variation II (2%) has 28.21%. Variation I (1%) have 13.07% moisture, whereas Variation II (2%) has 13,15%. Variation I (1%) contain 0.233% fat compared to variation II (2%) of 0.223%. Variation I (1%) had 1.445% ash content, whereas Variation II (2%), contained 2% ash. The nutritional value of Grade II or dried noodles with Spirulina platensis conforms to Indonesian National Standard 8217-2015. Spirulina platensis increases the pro-tein content of dry noodles when added. According to SNI 8217-2015 grade II, the addition of spir-ulina to dried noodles improved their protein, water, ash, and fat content. The nutritious content of dried noodles was improved by the inclusion of Spirulina platensis.
