The purpose of this article is to examine the conversion of waste methane gas to renewable energy through environmental management. Processing organic waste is one kind of alternative energy that may be generated and regenerated. Garbage is a major issue for the majority of people, particularly the vast volume of market garbage. Waste processing and utilization technology is required. Implementing the 3R process of reduce, reuse, and recycle on fresh garbage not only generates useful goods, but also addresses the waste issue and generates revenue for those who wish to manage it. As a result, it is critical to evaluate the design of organic waste burners that convert methane gas to methane and to estimate the rate of combustion and heat produced by organic waste biogas

Saccharomyces cerevisiae is an important yeast has been exploited for a long time to produce alcohol or bread. Moreover, genetically engineered S. cerevisiae cells continue to be used as cell factories for production of biofuels, pharmaceutical proteins and food additives. Genetically modified strain of S. cerevisiae created using traditional methods is laborious and time consuming. Recently, originally an immune system in archaea and bacteria, Clustered regularly interspaced short palindromic repeats “CRISPR” and CRISPR-associated “Cas” have been used exploited as a flexible tool for genome editing. Until now, this tool has been applied to many organisms including yeast. Here, we review the importance of S. cerevisiae as an industrial platform and the use of CRISPR/Cas system and its applications in research and industry of this yeast.

Research on amphibian diversity in Rivers State, Nigeria, was conducted between 2015 and 2019. The survey covered seven Local Government Areas and three ecological zones (lowland forest, freshwater swamp and short mangrove). The surveyed areas were Ikwerre LGA (Isiokpo), Emohua (Rumuji and Ndele), Okrika (Fiberesima Polo, ATC sandfill, Greame Ama), Khana- Ogoni (Bori, Kaani 1), Ogba-Egbema-Ndoni (Omoku), Ahoada East (Ahoada main town, Ikata) and Obio-Akpor (Agbada, Rumuagholu, Rumuesara). The habitats included farmlands, fallow areas, swamps, streams and inundated areas, bush paths, human settlements and forested areas. Visual encounter and acoustic survey methods were used. Nineteen amphibian species were encountered including members of the Arthroleptidae, Bufonidae, Dicroglossidae, Ranidae, Hyperoliidae, Ptychadenidae and Pipidae. Freshwater swamps and short mangrove ecological zones (characterized by human settlements and farmlands) had the lowest diversity of two and five amphibian species, respectively. The highest diversity comprised of eighteen different amphibian species was recorded in forested habitats of the lowland forest/freshwater swamp ecological zone. 569 individuals were collected from lowland forest/freshwater swamp ecological zone; 215 from lowland forest; 60 from short mangrove; and 28 from freshwater swamp ecological zone. Shannon diversity was highest in the lowland/freshwater swamp ecological zone (H=2.12) and lowest in the freshwater swamp zone (H=0.52). It is concluded that a forested habitat comprised of the combination of lowland forest and freshwater swamp ecosystems hosts a greater diversity of amphibian species.

This study examined the use of antenatal services among women in farming communities in Kogi State, Nigeria. A multi-stage sampling technique was employed to collect primary data from 150 randomly selected farmers through the use of structured questionnaire. The data was analysed using descriptive statistics and logit regression model. Analysis of socio-economic variable revealed that majority (73.4%) of the respondents were below the age 40 years, with a mean household size of 6 members. About 94.7% of the respondents used antenatal care services covering an average distance of 4km in getting to nearest health facility. The study also revealed that majority (92.7%) of the respondents were aware of healthcare facilities availability and they mostly got their information from family members and friends. The use of antenatal care services among women was high and majority (95.3%) of the respondents had the knowledge of where antenatal centre is located. Also majority of the respondents visited those centres in their last pregnancy with frequency of visit between 1- 4 times. Previous visits, nearness to ANC centres and formal education positively influence the use of ANC services among women in the study area. High cost of antenatal services and poor level of information were found to be the most significant challenges facing women access to antenatal care services. We recommend that government should subsidize health care services for women in order to improve their affordability.

A feed is one of the components that supports a cultivation business activity, fish feed must have good nutrition, especially a source of protein. Sources of protein for fish feed ingredients are generally imported, such as peanut meal and fish meal. Utilization of fishery and industrial waste as fish clothing is an effort to overcome the relatively high cost of feed. This study aims to determine the effect of adding formulations on the chemical properties of industrial waste-based catfish feed. The results showed that the more fish meal formulations that were added could increase the protein content in a range of 22.90% -39.90%, fat 5% -7.70%, and ash 5.79% -11.36%. The carbohydrate content decreased with a value range of 33.87% -57.08% and water 7.14% -12%. Fish feed formulations that are close to the SNI for catfish feed are found in treatment P1 with 39.90% protein content test results; water 7,18%; fat 7,7%; Ash 11.36% and carbohydrates 33.87%.

Seed priming is a pre-sowing treatment used to reduce stress effects in crops .This technique has been used to increase the germination rate of seeds mainly under unfavorable environmental condition. Crop productivity faces many problems like that unavailability of suitable condition that causes unbalanced seedling growth and poor germination. Hormones are essential to improve plant growth, development, crop yield quality and quantity. Auxin is essential hormones that improves germination of seeds and reduce stress effects. Laboratory experiment was conducted to study the effect of seed priming using different concentrations of IAA and IBA on carrot seeds (Daucus carota). In laboratory experiment, three concentrations of IAA and IBA (75 ppm, 50ppm, 25ppm) treated with distilled water with priming duration of 24 hours. Experiment was laid out in CRD with three replications. Data was collected to investigate the effect of seed priming with IAA and IBA under these condition like that (fresh weight, dry weight, speed of germination, root length, seed length, seedling length, final germination rate, mean germination time and dry matter content). Maximum fresh weight, final germination percentage, seedling length, energy of germination, speed of germination and mean germination rate was recorded IBA 75ppm. Maximum dry weight and dry matter content was observed IBA 25ppm.Maximum shoot length was recorded IBA 50ppm. Non-significant difference was recorded in root length.

Edamame is an agricultural product famous as vegetable soybeans. One of the edamame processed products is frozen edamame. Frozen edamame is a unique product frozen of souvenirs from Jember. This product is vulnerable to quality degradation due to the environment and consumer treatment. Consumers buy and carry products for souvenirs in a long journey and consumers are less precise in handling storage again when out of frozen storage. This study aims to improve the influence of storage room temperature with different time on the physical and chemical quality of original frozen edamame seeds and the influence of long storage with different time on the original organoleptic characteristics of frozen edamame. The results of tests conducted on the original edamame product during storage at room temperature affected the test results on color, texture, pH, total acid, moisture content and antioxidant activity, but had not effect on the total dissolved solids. The longer of storage at room temperature, the value of texture, color, total acid increases while the total dissolved solids, pH, moisture content and antioxidant activity decrease. The panelists organoleptic test assessment of the product during room temperature storage, panelists preferred P0 (0 hours) because the product was in fresh condition and of good quality compared to other treatments. During product storage at room temperature with different treatment times, the quality of the product has decreased in terms of color, texture, aroma, and taste.
