Abstract

The characteristics of waste composition and community behavior are important data for making an appropriate domestic solid waste management plan. However, these data are lacking or not studied in Bac Lieu, especially in rural areas. Therefore, the study was conducted to determine the domestic waste composition and evaluate the factors related to the knowledge, attitude and practice (KAP) level of the community in domestic solid waste management in Phuoc Long district, Bac Lieu province, Vietnam. The results of domestic solid waste samples collected at households showed that the waste was composed of organic (73.8%), recyclables (15.7%), hazardous waste (0.7%), and others (9.9%). Plastic bags (42.7%) and papers (30.5%) were predominant in the recyclables. The interview of 150 households indicated that the majority of respondents had an average level of knowledge (46%), and attitude (49.3%). However, 46% of respondents had an inadequate level of practice. In addition, the study observed that respondents have a good level of knowledge and attitude that leads to good practice. The Chi-square test showed that the KAP level of the respondents is influenced by demographic factors including age, education, occupation and income (p<0.05). In which, education level and age were the significant influencing factors. The results indicated that education for improving the community’s knowledge and attitudes in domestic solid management should pay more attention on the population aged over 60 years and those with occupations belonging to agriculture and housework.

Abstract

Understanding communities perceptions and attitudes towards participatory forest management (PFM) is crucial to successful PFM improvement. However, there is a lack of research evidence on the perception of local communities for PFM program intervention. The purpose of the study was to exmine local community perceptions and attitudes towards PFM intervention. In this study, 131 households were surveyed and data were collected through the household survey; key informant interviews (KIIs), focus group discussion (FGD). Descriptive statistics were used to analyze the data. Results show that the households perceived that there is no deforestation after PFM intervention. This increased species diversity, forest coverage, productivity of the forest, number of valuable species and address environmental degradation. Respondents that PFM program has opportunities to change a negative attitude to a positive through giving of power to the local community, enables to exclude non-PFM members, and creates a sense of belongingness to use and conservation of forest. The finding demonstrated that households generate their incomes from different sources and the share of forest income is the second. The different actions such as better protection of existing forests, access to alternative livelihood, access to better knowledge were suggested to increase the existing benefits and management of PFM. The finding of the study suggests further improvement of local communities’ perception and attitudes as well as providing alternatives to improve forest conditions and livelihood.

Abstract

The aim of this study is to elucidate some of the basic characteristics of manure and its biochar and to explore its potential as a solid fuel and soil amendment. Cow, pig, chicken, and duck manure were selected and collected in the farmer’s pen. Furthermore, composite sampling was applied to obtain a representative sample of each manure. Each of them was dried in the sun for four to seven days, and each sample was divided into two parts. The first part was not further processed, while the rest were carbonized. Carbonization was carried out within a temperature range of 300 to 400?C and 4 h residence time. C-organic, N-total, available P and K, CEC, volatile matters, fixed carbon, ash content, Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), Sulfur (S) content), higher heating value, and the chemical composition of their ash in both original and carbonized manure were identified. In addition, the nutritional content was relatively comparable and the H/C and O/C ratio in biochar were lower than in its original state. Both the original and carbonized manure indicated low calorific value, while the ash content and fouling index were high. The results showed that livestock manure in both forms has more potential as a soil amendment than solid fuel.

Abstract

A study area was at the Musi River, located in the southern part of Sumatera Island, Indonesia. This river flows in the southern area with a majorly tropical rainforest climate. For decades, it has become a substantial port used mainly for the transport of rubber, petroleum, and oil palm, which has the potential to threaten the area. Therefore, the objective of this study was to investigate the impacts of these activities by evaluating the water quality status and pollution index in the Musi River. Physicochemical parameters such as pH, salinity, temperature, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) were measured along the river. Results of the study revealed the impact of agriculture and fish farming activities in the upstream area has affected the pH values of the water became slightly acidic. In addition, COD values at all stations were found to be high and made they could not be used for drinking water. TSS values were also found to be high at the downstream stations. According to the pollution index status, the study area was classified from low to moderate pollution.

Abstract

The use of chemicals in practical activities or research in the laboratory will certainly produce wastewater. Wastewater generated from the laboratory is classified as hazardous and/or toxic waste. Based on the substances contained in laboratory wastewater in terms of accumulated amount and a long period of time, wastewater will pollute the environment and will have an impact on living things around it if it is directly discharged into water bodies. The composition of laboratory waste is reactive and dangerous because it contains heavy metals Pb, Fe, and Cu as well as high Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) so it is difficult to decompose in nature. This study aimed to prepare the laboratory wastewater using the coagulation process as pretreatment. Therefore, this research prioritized the reduction of heavy metal levels of Pb, Fe, and Cu and reduced the content of COD and TSS with Alum as a coagulant. The highest degradation percentage of COD and TSS content occurred at the Coagulation Dose of 80 ppm, namely 99.79% and 99.80% respectively. Meanwhile, the highest degradation percentage of heavy metal levels of Pb, Fe, and Cu as well as the optimum COD and TSS content occurred at a stirring time of 60 minutes respectively, which were 49.48%, 58.96%, 94.09%, 99.97%, and 99.40%. It was concluded that the pretreatment of laboratory wastewater using the coagulation process could reduce the levels of Pb, Fe, and Cu metals, and the content of COD and TSS.
