Abstract

Antioxidants are compounds that can capture free radicals. Green tea is an herbal beverage that contains antioxidants. Non-dairy creamer is an additive made from vegetable oil. Green tea can be made into powdered instant beverages with the addition of non-dairy creamer. This study aimed to determine the effect of the addition of green tea extract on organoleptic properties, acceptability, antioxidant content, nutritional content, and the results of the economic value of non-dairy creamer functional beverage products. The research design used was a complete randomized design (CRD) using three treatments, namely the addition of 0.8 g, 0.9 g, and 1.0 g of green tea extract, with three replications. Organoleptic test was conducted on each treatment to determine the best treatment in terms of taste, color, and aroma. Antioxidant activity test was also performed on each treatment. A proximate test was then conducted on the best treatment to determine the nutritional content. The results reveal that the addition of green tea extract has generated a significantly different effect on organoleptic properties and antioxidant activity in non-dairy creamer functional beverages. The best treatment was F1, namely the addition of 0.8 g green tea extract, which has generated results in the form of color 4.05, taste 5.67, aroma 4.15 on a scale of 1–7, then antioxidant activity of 4,973.53 ppm, water content 1.42%, ash content 1.35%, protein content 2.30%, fat content 2.13%, and carbohydrates 90.52%.

Abstract

Varieties and spacing are among the factors determine crop yield. Field experiment was carried out at the North Core College of Agronomy Teaching and Research, Joseph Sarwuan Tarka University, Makurdi to determine the effects of intra row spacing on the performance of three maize varieties in Makurdi. The experimental design used was 3 x 4 factorial arrangement laid out in a Randomized Complete Block Design, replicated thrice. The treatments were three (3) maize varieties and four (4) different intra-row spacing (20 cm, 30 cm, 40 cm and 50 cm). Data were collected on growth, yield and yield component parameters were subjected to analysis of variance. Significant means were subjected to least significant difference (LSD). The result showed significant differences among the maize varieties, row spacing and treatment interactions which indicated the presence of genetic and environmental effects on maize performance. The superiority of Sammaz-51 over the other varieties was observed as it produced significant seed yield. Result showed increase in intra row spacing with increase in more number of leaves per plant which were significantly longer and wider while least was recorded in a closer spacing. Increase in plant spacing beyond 40 cm intra-row was found to reduce cob weight, weight of seeds per cob as well as 1000-seed weight. Based on the study findings, maize farmers were advised to adopt increase intra-row spacing up to 40 cm for optimum yield of maize in savannah region of Nigeria.

Abstract

There are several types of environmental pollution in rural areas in Glagah Subdistrict, Lamongan Regency, such as water, soil, and air pollution. Air pollution occurs because the Glagah Subdistrict is crossed by the inter-regency axis road, which is travelled by many vehicles. Meanwhile, water and soil pollution in this area occur due to fish farming and ponds. In addition, Glagah Subdistrict in Lamongan Regency is considered a flood-prone area due to high rainfall that causes the overflow of Bengawan Solo River. This study aims to determine the quality of the rural environment in Glagah Subdistrict. This study used survey and questionnaire methods. Data were analyzed quantitatively using statistical calculations and frequency tables supported by descriptive analysis. The research parameters observed were environmental quality, disaster-prone potential, and the existence of disaster response by the local village government. The results of this study show that villages in Glagah Subdistrict do not experience air or soil pollution, as they are located far from industrial areas. Instead, water pollution occurs every year, characterized by the proliferation of water hyacinth that covers the surface of the rivers, thus inhibiting the flow of river water. Potential disasters in Glagah Subdistrict are flooding and tornado. Flooding occurs in seven villages located near Bengawan Jero (a tributary of Bengawan Solo) and can be categorized as annual flooding. Villages that are annually affected by flooding do not have disaster mitigation plans, even though funds for such activities are available. Therefore, cross-sectoral cooperation is needed to overcome the annual flooding in Glagah Subdistrict.

Abstract

The sacha inchi plant (Plukenetia volubilis L.) produces seeds with high protein content that are beneficial for human health. The planting of sacha inchi on sub-optimal land, such as inceptisol soil, requires eco-enzyme, an organic fertilizer made from environmentally friendly fermented fruit waste. In addition, the use of biological agents, such as arbuscular mycorrhiza, can increase the plant’s ability to absorb macronutrients, such as potassium and phosphorus, from the soil. This study aims to determine the effect of eco-enzyme and mycorrhiza treatments on the growth of sacha inchi plants on inceptisol. A two-factor group randomized design with nine treatments and three replications was employed. The first factor was the concentration of eco-enzyme (0 ml/l, 22.5 ml/l, and 30 ml/l). The second factor was the dose of mycofer (substance containing mycorrhizal spores) (0 g/plant, 30 g/plant, and 40 g/plant). Parameters measured were plant height, number of leaves, root length, root fresh weight, root dry weight, and mycorrhizal infection. The results show that the application of eco-enzyme was able to increase the height of sacha inchi plants in the vegetative phase at 10 and 20 days after planting (DAP) and increase the number of leaves at 30 and 40 DAP. Single application of 40 g/plant of mycofer was able to increase the vegetative growth of sacha inchi on inceptisol. The optimum amount to increase the growth rate of sacha inchi plants was reached through the combination of eco-enzyme at a concentration of 22.5 ml/l and mycofer at a dose of 40 g/plant.

Abstract

Scientific journals serve as benchmarks for academic achievement, aiding researchers in publishing their work and assisting others in locating high-quality sources. Enhancing accreditation is crucial for elevating the competitiveness of the University of Lampung, not only on a national but also an international scale. This is integral to realizing the vision of the University of Lampung, set to become one of the Ten Best Universities in Indonesia by 2025. Therefore, a journal acceleration model is needed to support journals at the University of Lampung to become journals with global reputation. The objective of this research is to develop a model for journal acceleration policy. The methodology employed to establish the acceleration model for this journal is a SWOT analysis, a strategic planning method utilized to assess the strengths, weaknesses, opportunities, and threats within the institution (University of Lampung). This assessment is conducted through Focus Group Discussion (FGD) activities, employing Participatory Rural Appraisal (PRA) techniques, and in-depth interviews. The results of the study of the accelerated accreditation model for journals with global reputation with the SWOT strategy in S-O collaboration (Strengths and Opportunities), namely collaborating with international institutions to send and share articles, coaching for preparing Scopus documents from editors who are experienced in managing global reputations, increasing the internationalization of local journals under the University of Lampung. Furthermore, it highlights initiatives to promote collaboration among writers across countries, leveraging available facilities and conveniences to foster the development of international journals.
