Abstract

Despite establishing waste management boards and environmental agencies across states in Southwest Nigeria, household waste disposal remains poorly managed, with low consideration given to its reuse and recycling. Previous research has established the menace of improper household waste disposal in Nigeria. This paper examines women's household waste disposal methods and their awareness, willingness, and interest in waste management and recycling. This study was conducted in November 2021 with a sample of 436 women selected across six communities in 3 States in Southwest Nigeria (Lagos, Osun, and Ekiti states). In each state, one rural and urban Community is selected. Descriptive analysis and the ordered logistic regression estimation method were used to estimate the likelihood of women's interest in waste management and recycling. The Odd Ratio and the probability value at a 95% significance level were considered a measure of the strength of association between the variables. Most households in the communities had no evidence of waste trolleys or waste containers. Only 28% of respondent indicates an awareness of waste recycling. At the same time, statistical regression reveals Christians have high chance (Odd Ratio 30, 95% p<0.001) than the Muslim women (Odd Ratio10, p<0.001), having secondary education (Odd Ratio 8.9) and working in the informal sector (Odd Ratio 11.9) have positive association with women interests in waste management and recycling. At the same time, social stigmatization exhibits a negative relationship. Government participation in waste management and recycling was found inadequate and need to be upgraded to help provide a clean environment and support for waste-wealth creation among women. This paper argues that women's interest in recycling for wealth creation and a good environment is to be incorporated into the waste management and recycling process with adequate support.

Abstract

Many studies have shown the relationship between meteorological elements and air quality. However, some aspects of the relationship are unknown, particularly in Indonesia, which has a variety of topographical landscapes and climatic conditions. This study seeks to define the relationship between meteorological variables and the diurnal pattern of three pollutants that contributes to the so-called Indeks Standard Pencemar Udara (ISPU), similar to the Air Quality Index (AQI), in a remote area in Bukit Kototabang, West Sumatra, Indonesia. The three parameters, namely Particulate Matter 10 micrometers (PM10), carbon monoxide (CO), and tropospheric ozone (O3), were correlated with diurnal variations in temperature and relative humidity in the months of maximum rainfall and minimum rainfall in 2020. The T-test was used to obtain each parameter's mean and variance sizes and the significant differences among the parameters. The results showed that PM10 has a significant distribution when high and low rainfall, but no significant relationship exists between temperature and relative humidity. Carbon monoxide has significant fluctuations to differences in rainfall and diurnal variations in air temperature. Meanwhile, O3 shows a weak correlation to the rainfall variation but has a high correlation to diurnal variations in the temperature and relative humidity. The results suggest that air temperature can significantly affect the diurnal concentration of pollutants, which involves photochemical reactions in their formation, such as ozone and carbon monoxide. It also shows the potential for worse air quality during the low rainfall. As the pollutant level can be higher during the dry season compared to the rainy season, efforts to reduce the pollutant emission during the dry season, like forest and land fires, need to gain more attention.

Abstract

Currently, there are two practices to assess the environmental and social impacts of the power development projects in Indonesia, namely Indonesia Environmental Impact Assessment (EIA) or Amdal and Environmental and Social Impact Assessment (ESIA) based on the International Finance Corporation (IFC) Performance Standards. However, the ESIA practices in Indonesia, in particular, have yet to be thoroughly examined in the academic context. This research compares the procedural features and environmental and socio-economic aspect coverage of Indonesia's EIA against the IFC (IFC PS) ESIA. A document analysis was employed to systematically analyze the main divergences and similarities contrasted with applicable Indonesian regulations and IFC PS. The results show distinctive differences between Indonesia's EIA and ESIA regarding screening, public participation, scoping, the study of alternatives, impact analysis, review and decision-making, environmental management plans and follow-up, and complementary parallel studies. The research also found that EIA is lacking in covering aspects of ecosystem services, labor, groundwater, landscape and visual impacts, cultural heritage, community safety and security, and non-routine activity or unplanned events. The identified gaps could suggest improvement to ensure Indonesia's EIA and ESIA practices in Indonesia align and provide benefits for sustainable development.

Abstract

Biodegradable foam has been vastly developed to replace polystyrene foam. However, its water absorption capacity has become a significant obstacle to being used in food packaging. Therefore, this study aims to assess the effect of incorporating natural waxes as a coating material in producing biodegradable foams. The four natural waxes are soy wax, candelilla wax, beeswax, and carnauba wax. The biodegradable foams were fabricated with cassava starch and rice straw as natural fiber sources using a thermal pressing machine. The Meyer-Rod coating method was adopted to produce high contact angle and highwater resistance starch-based biodegradable foams. Water absorption analysis was performed according to the Cobb60, and water solubility analysis was conducted based on International Standardization for Organization 10634:2018 procedure. The result shows that the surface modification of starch-based biodegradable foams with natural waxes significantly improved water absorbency and water solubility. Moreover, it is demonstrated that the use of carnauba wax had the highest decrease of Cobb60 index of 1.5 g/m2 and the lowest water solubility of 2% after carrying water for 90 min. This study concludes that the utilization of natural waxes a as a coating material for starch-based biodegradable foam could replace conventional polystyrene foam for food packaging industry.

Abstract

Nigeria's low level of sanitation hygiene provoked the increasing prevalence and containment of infectious diseases such as bird flu, acute respiratory infections, Ebola, Lassa fever, polio, diarrheal, pneumonia, and dysentery. These diseases can attack vulnerable groups like children. Therefore, awareness of hand hygiene practices is still needed to prevent the spread of diseases. This study analyzed the exposure to campaign messages on hand washing and hand hygiene sanitation among secondary school students in Lagos State, Nigeria. A total of 620 students participated in the study and were selected through multi-stage sampling methods. Research instruments adopted included questionnaires and observation of hand hygiene facilities and practices among students. Quantitative data were analyzed through the Statistical Package for Social Sciences (SPSS). Findings show that about 97% of respondents are aware of the need to wash their hands. Furthermore, interpersonal sources of information on hand hygiene available to respondents included parents and family members (58.9%), followed by medical officers (13.4%), public health campaign organizations (11.7%), and teachers (9.9%). The three most dominant influences on hand washing practice among respondents are parents (46.4%), teachers (23.3%), the media (14.5%), and private business organizations (12.1%) in that order. Based on the correlation coefficient (r = 0.256; p = 0.000), the study established a significant positive relationship between exposure to campaign messages and hand sanitation among the study group, indicating that exposure to hand sanitation messages positively influences good handwashing behavior among school children. This study has implications for government authorities, policymakers, and development partners on the need to engage traditional and new media channels to complement interpersonal sources of information to enhance proper hand sanitation among students in Nigeria and other sub-Saharan African countries.

Abstract

The Indonesian batik is an intangible cultural heritage that contributes to the country's economy but raises environmental pollution. Synthetic dyes are considered to cause pollution, and the natural counterpart is recommended to replace it because natural dyes are considered more eco-friendly than synthetic ones. Therefore, this study examined the Blue Water Footprint (BWF) and Grey Water Footprint (GWF) of the batik household industry by applying synthetic dyeing and comparing the result to the natural dyeing from previous studies. This research used the Water Footprint accounting approach based on the Water Footprint Network, which involves identifying the batik process followed by measuring and calculating the consumptive water use representing BWF and degradative water use representing GWF. The BWF of batik-making process applying of synthetic dyes was 1000.914 L/day or 9.223 L/pc, and the GWF was 12,877.215 – 18,003.118 L/day or 95.39 – 142.88 L/pc. Washing consumes water most responsible for the high BWF, while dilution water for dye solution and wastewater dominates the portion of GWF. Applying both dyes produces wastewater whose quality exceeds the acceptable limit the Indonesian government sets, indicating that eco-friendliness should not be directly associated with synthetic or natural dyes. The selection of synthetic or natural dyes alone for batik production is not recommended since dyeing might be related to environmental issues and market preferences. The main problem lies in the batik artisans' general assumption regarding eco-friendliness linked to specific dyes, which needs to be improved by increasing water use efficiency with technology. Future research must focus on finding innovations to reduce water use in batik processing.

Abstract

This paper describes a business coaching activity for small and medium enterprises (SMEs) in chemical and waste management industries. Based on the analysis results, there was a lack of budgeting practice and suboptimal catalog marketing that comprised the majority of existing problems in SMEs. This research aims to assist the SME in improving its budgeting practice and product catalog. The method used is a qualitative method based on a business coaching approach. The research instruments adopted included in-depth individual interviews (IDI). The collected data was then processed and analyzed, starting with generating the SME's business process and service blueprint, followed by the business model canvas. Next, the paper also covers external and internal analyses, followed by the Gap and Pareto analyses to identify the priority issues. The owners of the SME have set a target to expand their business. However, various shortcomings can hinder the business. Most research finds that SMEs usually tend to be characterized by less financial planning, including the SME in this research. Many kinds of literature debate how to develop a budgeting process for SMEs as the vast majority of literature on management accounting for SMEs is still under-researched. Formulating a meaningful operating budget can give the business clear goals. The second issue is related to the catalog, which is one of its critical marketing channels. However, the catalog has not yet been enriched with better-quality content compared to the competitors. The research results have the potential to deliver positive improvements for SMEs across similar cases. Further, the contribution of this study may guide owners of businesses and policy-makers on how to develop guidance for SMEs to solve their issues with practical assistance in the future.

Abstract

Coal-ash slurry transportation via pipelines has been accepted as a potential, economical, and dependable mode of two-phase flow of solid-liquid transportation. It is solid-liquid transportation where the ash slurry generally flows through mild steel, and a good amount of pump energy and pressure is required to convey the slurry with a density above 1220 kg/m3. The study is basically on the water hammer analysis of ash slurry conveying pipes. Nevertheless, since the hammer analysis is typically carried out in normal water, the study of ash slurry is compared to the know criteria of potable water. The study aims to understand the flow characteristics of such pipelines. Investigators worldwide have been analyzing the flow experimentally, numerically, and theoretically. HAMMER and WaterGEMS software was used to carry out the hydraulic analysis of such pipelines and to monitor the maximum transient pressure head being developed. The above software was further used to monitor the maximum transient pressure head being developed due to a sudden power failure which caused the stoppage of the regular pump operation. A transient stress analysis was performed on the pipelines where the maximum transient pressure head was detected. For necessary safety measurements of the pipelines, the ultimate transient stresses were computed from the parameters observed in the software results to find whether such pipes are safe. In the same system, the transient head observed due to the slurry hammer was approximately two times the transient head observed in the water flow. The operational pressure incorporates the slurry pipeline pressure at a steady state to surmount friction and static heads. The code requires that the pressure level increase due to surges not exceeding at any time the internal design and implemented pressure of more than 10%.

Abstract

Rasbora philippina is an endemic species in Mindanao Island, Philippines. Its reproductive biology remains unstudied despite its economic importance to the local inhabitants of the lake, the Subanen tribe. Due to its marketability, Rasbora faces local threats. Thus, the formulation of fishery management and conservation recommendations is highly recommended. A research-made survey was used to interview fishermen in the lake, and fish samples were collected using a seine net with a catch per unit effort of three or four from March to May 2019. Water samples were collected using a Niskin water sampler at 1 m and 15 m depths during the same period. The reproductive biology of the fish was determined using the following data: sex ratio, maturity stages, age and population structure, fecundity, gonadosomatic index, and length-weight relationship. During the study period, the water quality was highly variable, still in good condition, and could still support the population of R. philippina. There were 31 male and 403 female individuals with a mean fecundity of 2,645.67, suggesting that there were more females than males, compensating for the low fecundity of R. philippina. The species does not spawn continuously, as mature individuals were absent throughout the study. However, this species is continuously recruited due to the presence of juveniles in the entire sampling period. Peak spawning was in early and mid-March and mid-April. Based on the results, we suggest that the open fishing season should be in early April, late April, and the third week of March, while the closed season for fishing would be in early March and late March. Thus, the management and conservation of R. philippina should always include careful consideration of the facts presented in this present work.

Abstract

Previous research on meandering rivers in Indonesia, precisely in Java, has predominantly focused on alluvial plains, while their presence is also observed in hilly regions with rocky substrates. The study aims to investigate different meandering types in Java and establish regional connections between these types and geological and geomorphological processes. The methodology involves identifying high-resolution remote sensing images and topographic data, followed by analysis based on geological and geomorphological developments. To categorize the rivers, sinuosity ratios are meticulously calculated. The tectonic setting, which influences physiography and geomorphology, is an analytical unit for determining the meandering process. The result reveals that meandering rivers are primarily located in the alluvial plains of northern Java. Meanwhile, meandering rivers in hilly areas are concentrated in structural formations, predominantly in southern and central Java. In alluvial plains, meandering rivers display a regular pattern with higher concentrations of curvature downstream, and their substrates consist of deposits or soil. Conversely, meandering rivers in hilly regions exhibit irregular and winding patterns, randomly distributed from upstream to downstream. These rivers are situated in the physiographic regions of Southern Mountains, Hills in Central Depression, and Kendeng Hills, and their substrates mainly comprise rocks, leading to a more protracted process of curvature transformation. In conclusion, meandering rivers in Java can form not only in alluvial plains but also in hilly areas. Meanders on hilly topography possess higher sinuosity ratios than those on alluvial plains, displaying irregular patterns. Energy minimization alone is not the sole controlling factor; the physical surface conditions also play a significant role, particularly in meanders in hilly areas, resulting in a diverse typology of meanders. Therefore, understanding the formation of meandering rivers in various topographic regions can serve as a basis for policymaking, particularly in flood mitigation and riverbank erosion management.
