Abstract

The sole purpose of a compacted landfill liner is to contain and mitigate the impact of leachate on the environment. This research assessed the engineering properties of bentonite enhanced termite mound mixture to ascertain their suitability as an alternate landfill liner. The mixture of mound soil and bentonite was proportioned by percentage weight as (100:0), (95:5), (90:10) and (85:15) respectively. The compaction analysis reveals an optimum moisture content ranging from 13.80% to 18.52% and a maximum dry density that varied from 1.72 g/cm3 to 1.88 g/cm3. The hydraulic conductivity result of 15% bentonite-mound soil mixture (0.23 x 10-9 m/s) established hydraulic conductivity less than 1 x 10-9 m/s, which satisfied the criteria for landfill liner. Hence, a mixture of 15% bentonite enhanced mound soil is found suitable as an alternate bottom liner.

Abstract

Considering the content of various elements in coal fly ash (CFA),  it has the potential to be used as an additional source of nutrients in the soil. However, the use of CFA for agriculture is still debated because CFA contains several metal elements. The purpose of this study was to study the CFA phytotoxicity to seed germination and metal uptake by plants on acid soil. The first experiment was the study of the effect of extracts of various CFA and soil mixtures (5% - 45% CFA) on the germination of mustard seeds. The second study was a CFA phytotoxicity test for plant growth and metal uptake by the mustard plant. Results of the first experiment showed that the application of CFA had no significant effect on mustard seed germination, but had a significant effect on radicle length. CFA application increased the uptake of Pb and Cu by plant along with the increase in the proportion of CFA in the CFA + soil mixture. The contents of Cu and Pb in the mustard plant due to CFA application up to 30% were still below the threshold levels of Cu (36 ppm) and Pb (2 ppm).

Abstract

Local cassava agro-processing industries in Nigeria generate toxic organic effluent with negative environmental impact if disposed without adequate treatment. This study examines the performance of a lab-scale aerated sequencing batch reactor (SBR) in degrading cassava mill effluent using palm kernel (Elaeis guineensis) shell (PKS) as biofilter media. Wastewater samples were collected before and after flowing through each compartment at hydraulic retention times of 3, 5 and 7 hours. Continuous aeration and nature-based degradation of the effluent recorded overall removal efficiencies of 73.5% (Hydrogen cyanide), 70.59% (BOD), 69.18% (COD), 29.93% (Turbidity), 4.92% (Sodium), 25% (Magnesium) and 14.32% (Calcium) respectively. Effluent electrical conductivity (EC) slightly increased by 7.84%. The Sodium Adsorption Ratio (SAR) of the treated wastewater ranged from 6.9 to 7.3 while the final pH ranged from 4.5 to 4.6. The values of EC, BOD and COD were significantly different (P<0.05) along the treatment sequence, confirming the effectiveness of the chambers in reducing these pollutants. Despite achieving high removal efficiencies, the final values of most parameters still fall short of the local permissible limit signifying operational limitations and the need to optimize the system to reduce key contaminants to safe disposal limits

Abstract

Indonesia has an abundant amount of basalt rocks resources, including in East Lampung Regency of Lampung Province. This basalt has not been used optimally and only be used as a foundation. The use of basalt as soil fertilizer also known as the stone meal. This study focused on the effect of using basalt dust on the growth and development of organic fertilizer application for the cassava plant. This study is to support the local government policies that declared Lampung as a national development centre of cassava, with a production rate of 30.8% of the national production of cassava. Basalt powder was characterized using test petrograph and X-ray Fluorescence (XRF) for a description of microscopic and chemical composition. The test results were used to determine the chemical composition of rock classification using the TAS diagram. The experiments of applying fertilizer on cassava crops in the demonstration plots 8 treatment x 3 repetitions were conducted by adding the percentage by weight of the basalt towards organic fertilizer between 0% (control 1), 10%, 20%, 30%, 40%, 50%, 60%, and without treatment (control 2). The results indicated that basalt from East Lampung is classified as olivine Tholeite basalt which is rich in CaO, Mg and Na2O + K2O. The growth rate of cassava plants which are affected by basalt powder presentation is characterized by a value which is higher than the value of CGR control, and recommended to not exceed 10% of the weight of basalt fertilizer.

Abstract

The use of agricultural lime ameliorant or rice husk charcoal combined with inorganic fertilizers is one of the agricultural intensification efforts in peatlands. This study aimed to find out the influence of various ameliorant types and nitrogen, phosphorus, and potassium inorganic fertilizer doses application on growth and yield of maize in peatlands soil was conducted in Siantan Hulu Village, Pontianak City, West Kalimantan used. This study used a split-plot design with the main plot of ameliorant types (A) consisting of three treatments i.e. without ameliorant (A0), agricultural lime of 3 t/ha (A1) and rice husk charcoal of 3 t/ha (A2). The subplot was inorganic fertilizer doses (B) consisting of three treatments i.e. B1 = 50% of N, P, and K inorganic fertilizers, B2 = 75% of N, P, and K inorganic fertilizer, and B3 = 100% of N, P, and K inorganic fertilizers. Observation on crop growth consisted of crop height, number of leaves, leaf area, crop total fresh weight, crop total dry weight, and crop growth rate. Yield observation consisted of ear length, ear diameter, 100-dry seed weight, seed yield weight per hectare, and harvest index (IP). The results of the study indicated that rice husk charcoal application of 3 t/ha gave seed yield weight of 7.25 t/ha that was higher than that of agricultural lime that produced 6.34 t/ha seed yield and without ameliorant that produced the lowest seed yield of 4.18 t/ha. Application of N, P, and K inorganic fertilizer dose of 75% produced an insignificant difference seed yield compared to the dose of 100%, which were 6.32 t/ha and 6.69 t/ha, respectively. Therefore, the application of N, P, and K inorganic fertilizer dose of 75% is recommended as a basic of maize fertilization.

Abstract

There is a long-standing debate on the relationship between land-related investments and tenure security and most studies in this sense fail to reach a concrete conclusion because of their focus on one side. This paper has employed a separate analysis for short-run farm investments as represented by spending on farm inputs and long-term investments as represented by hours spent on stone bund building in an attempt to solve this problem. Two Tobit models were estimated to analyze household level determinants of land-related investment decisions by smallholder farmers in Ethiopia and its tenure security implications. The findings revealed that there is no meaningful and significant relationship between tenure security and land-related investments decisions. Poverty status, rather, was found to exert significant negative pressure on investment decisions. Productivity, livestock holding, communal conservation around plot and participation in local government activities are found to be the major determinants of land investments.

Abstract

Combining the application of organic manure with inorganic fertilizer treatment can improve the productivity of the cucumber. Biogas slurry is synthesized from organic manure that can improve soil fertility and increase the yield of cucumber. This research aimed to learn the effect of biogas slurry and inorganic fertilizer on soil fertility and its impact on yield of cucumber and to learn the role of biogas slurry in decreasing amount of inorganic fertilizer used on the crop. This research was conducted in former paddy field located in Wriginsongo village, District of Tumpang, Malang Regency from March to May 2017. A randomized block design factorial was used with biogas slurry treatment as the main plot which consists of three levels: 10 t ha-1, 20 t ha-1, and 30 t ha-1while the subplot was the dosages of inorganic fertilizer which consists of100%,75%and 50% dosage of recommendation. This research revealed that biogas slurry treatment could increase the organic matter on the plant. There were some interactions between biogas slurry and inorganic fertilizer in the number of fruits produced, the weight of the fruit, the total weight of fruit produced per plant and hectare. Biogas slurry improved organic matter from 0.29% to 2.06%, N total from 0.06% to 0.15%, P2O5 from 93.48 ppm to 224.31 ppm, K2O from 2.01me 100 g-1 to 100 me 100 g-1, and C/N ratio from 3 to 9.

Abstract

Landslides are one of the natural disasters that cause severe damage to life. The frequency of landslide has increased with global climate change and population growth, so early warning efforts are needed. Rain is a trigger factor for landslides can be used as an approximate model for disaster prevention and mitigation through the estimation of rainfall threshold. The purpose of this study was to determine the characteristics and threshold of rainfall that triggered landslides in the Grindulu watershed. The method used is the Cumulative Rainfall Threshold (CT), this method compares the amount of rainfall for the last 3 days (72 hours) with rainfall 15 days before. In the Grindulu watershed, landslides occur during 3-day cumulative daily rains ranging from 23-464 mm, whereas in the 15 days before the events range between 67-756.5 mm. Estimates of lower threshold rainfall are determined linear so that the equation P3 = 0.4675 P15-46.9 is obtained with the value R2 = 0.5774The threshold value of rainfall triggers a landslide in the Grindulu watershed when the cumulative rainfall of 3 days is 40 mm and 15 days before the event is 320 mm. The determination of rain threshold is expected to increase community preparedness for landslides.

Abstract

A study of Collembola on land affected by pyroclastic material of Kelud Volcano, Ngantang Malang was conducted to elucidate the abundance and diversity of soil Collembola in a volcanic environment at various elevations. The study area was divided into two habitats, affected and unaffected by pyroclastic materials at each altitude of 900 m above sea level (asl), 1000 m asl, and 1100 m asl. The research was carried out in June 2019 using a stratified purposive sampling method. Soil Collembola was collected on litter and soil layers using a square frame, length and width of 20 x 20 cm to a depth of 5 cm. Litter and soil layer samples were extracted using Modified Berlese Funnel. Collembola was identified based on morphospecies up to the genus level. Each genus was found only one species, therefore genus was considered as a species. Results of the study showed that soil Collembola on land affected by pyroclastic has 20 species and an abundance of 8790 individuals/m2. In the pyroclastic unaffected areas, were found 33 species and an abundance of 3865 individuals/m2.  Entomobrya sp. was dominant in the litter and soil layers of all the study areas. This indicates that Entomobrya sp. is a species that is easy to adapt and has high habitat tolerance.
