Abstract

This study was aimed at assessing both the effect (risk) and impact of a recent oil spill on heavy metal concentration in the Santa Babara River in Bayelsa State, Nigeria. Samples were collected and preserved based on standard methods. The heavy metals of interest were Mercury (Hg), Arsenic (As), Cadmium (Cd), Chromium (Cr) and Copper (Cu) due to their levels of toxicities and presence in water bodies while the five study stations were Worokuma (W), Uwanga (W), Tuweni (T), Shellikiri (S), Inarakiri (I) and Esenfakiri (E). The solar thermos elemental flame atomic absorption spectrometer (AAS), model SE-71096 made in Germany with detection limit of 0.001 mg·kg−1 was used for the heavy metal analysis. The trend of heavy metal abundance was found in this order Cr>Cu>Cd>Pb>Hg=As. All the detectable metals had risk index of greater than 5 but the highest was found in the order, Cd> Pb > Cu > Cr (149, 35, 26 and 12 respectively) which meant extremely high level of pollution. This also indicated the probability of non-carcinogenic effects occurring and increases as HI increases signifying carcinogenic risk via direct ingestion of water. Graphs were used to show trends in both mean heavy metal concentrations and risk assessment indices. Chromium and Pb had moderate contaminations for CF and CDI values, hence regular monitoring of the Santa Barbara River is of essence as most of the inhabitants take this as the only source of potable water as their wells have very high iron content.

Abstract

North Semarang District is one of the areas that is often affected by tidal floods. This study will discuss flood distribution through tidal flood susceptibility mapping and identify adaptations. The first step is to carry out flood susceptibility mapping using DEMNAS data and sea tides. The second stage is to determine the key areas based on the tidal flood susceptibility map made. Key areas are useful for identifying forms of community adaptation to tidal floods through data collection in the form of observations and interviews. The mapping results show that the flood susceptibility area reaches 582.89 Ha or around 50% of the area of North Semarang District. The key areas with high susceptibility are settlements on Jalan Tambakrejo, Tanjungmas Village and it is known that the community responds by adapting patterns to changes in physical infrastructure, economic activity, and social development.

Abstract

Farmers’ consistency in adopting improved crop varieties is capable of guaranteeing sustainable development via high productivity and enhanced food security. The study assessed the effects of adoption of Improved Onion Varieties (IOVs) on farmers’ productivity in Kudan Local Government Area (LGA) of Kaduna State, Nigeria. Two-stage sampling procedure was used to select 111 onion farmers from four Wards in the LGA. Structured interview schedule was used to obtain required data. Descriptive statistics (frequency count and percentages), and ANOVA were used to analyse the data. Results shows that the average output before adoption was 3.29 while the mean after adoption was 4.55. ANOVA showed a significant difference between the adopters of improved onion varieties and non-adopters; F(1.109) = 154.91, P<0.001. The major constraint to adoption of IOVs was high cost of improved seeds (=4.81). This paper concludes that the adoption of IOVs has effect on the productivity of onion farmers. The National Agricultural Seed Council should ensure availability of improved seeds by fast-tracking seed multiplication and distribution to farmers so as to increase the sustainable adoption of IOVs.

Abstract

Based on the 2013 curriculum and Regulation of the Ministry of Education and Culture number 20 of 2016 concerning Achievement of Graduation Standards, graduates must not only be equipped with factual, conceptual, procedural knowledge but also metacognitive knowledge related to the field of knowledge, which is science. Metacognition can be measured by certain evaluation tools, so the instruments used in the learning assessment are oriented towards metacognition abilities. One of the characteristics of metacognitive assessment is that it involves students in their self-assessment process. Self-assessment is a habit of thinking about the relationship between metacognition and reflection. Metacognitive self-assessment is a metacognitive assessment instrument developed in this research, consisting 20 questions of metacognitive ability test and reflection journal as a self-assessment. This study aims to test the feasibility, analyze the characteristics of the product and determine the metacognitive profile of students. The results of data analysis showed that the Metacognitive Self Assessment product was very feasible with an average percentage obtained of 92.78% according to material experts, 86.43% according to evaluation experts, and the feasibility of readability data based on student responses of 83.59%. Metacognition profiles data based on their level are also supported by the results of reflection journals as a form of self-assessment that students have been able to carry out the process of reflection and evaluation of learning and what they are doing.

Abstract

Madukismo Sugar Factory used Ametryn and 2,4 d.amine as herbicides, and Urea, NPK, and ZA fertilizers, in its sugarcane cultivation process. This study performed life cycle assessment to see its environmental impact and proposed sustainable improvement efforts. The factory's sugarcane cultivation was found to account for 1041.085927 kg 1,4-DCB- Eq of Freshwater aquatic ecotoxicity-FAETP 100a, 6.702603784 kg 1,4-DCB-Eq of Terrestrial ecotoxicity-TAETP 100a, 689.8995889 m2a of Land use– competition, and 171.1111422 kg antimony-Eq of Depleted abiotic resources. The improvement could be made by applying biological pest controls, such as trichogamma chilonis, Cotesia flavipes, Sturmiopsis inferens, Tetrastichus scoenobii and elasmus zehteneri. The NPK, ZA, and urea fertilizers should also be used according to the standard operating procedure set by the Ministry of Agriculture, particularly regarding its amount and duration (at least twice a year). Manure could also be used to decrease dependency on synthetic fertilizers. Filter cake should also be used as organic fertilizer in sugarcane cultivation.

Abstract

Synthetic plastic made from the synthetic polymer polypropylene (PP) is generally used as food packaging, which over time causes environmental problems, so innovation in food packaging in the form of edible bowls is needed. Edible bowls are made from papaya skin pectin, wheat flour, gelatin flour, vegetable oil and water which are baked using oven technology. Based on tests, edible bowls have a water absorption capacity of 3% to 23%, can last for 18 minutes at a high temperature of 90℃ and 31 minutes at a temperature of -10℃, and can decompose within 2 to 3 months. This edible bowl made from papaya skin is an alternative substitute for plastic packaging, thus tackling the problem of plastic waste in Indonesia.
