Abstract

In agriculture practices, besides animal, human activity belongs to the enemy of Grey-headed Lapwing (Vanellus cinereus). This study aims to analyze the farmers’ perception on Grey-headed Lapwing existence in paddy field surrounding Gifu University, Japan. There are 10 farmers who are work in the research area. All of them are farmers. Descriptive method was used in this study, the data were collected with questionnaire. The finding show that farmers ignore the existences of Grey-headed Lapwing. They saw the nest of Grey-headed Lapwing in unplowed area as many as 60% and they found the nest in plowed area (soil tillage) as many as 40%. Although Grey-headed Lapwing has great defense to attack the enemy, but they prefer breeding in safety place. In this case, when human activity do their work in soil tillage period, it can ruin the nests. It means that human activity is one of the factors that influencing the breeding success of Grey-headed Lapwing.

Abstract

This study analyzed farmers’ perceptions about plant protection capabilities of extension workers in enhancing maize production in remote District Shangla Khyber Pakhtunkhwa-Pakistan. Educating farmers about modern technologies of crops is the mandate of the extension staff of the provincial agriculture extension department. For this research, two villages were taken purposively from three union councils of Tehsil Besham of District Shangla for data collection through a well-structured interview schedule. A total of 204 farmers were selected for data collection, which was analyzed using SPSS V.20 software. Descriptive statistics, 5 points Likert scale, and Chi-square tests were used. About 32% of respondents were found in the age 26-35 years, 46.6%  respondents have 1-2 acres of land under maize crop while 57.8% maize growers were literate with 20.1% respondents educated up to matric. Maximum (82.4%) growers were getting 6400-12800 kg/acre maize production by cultivating local varieties. Awareness about alternative pest management technique was ranked 1st with the highest mean value of 3.04 and standard deviation of 1.13, and performing pest monitoring on maize were ranked 2nd with a mean value of 2.84 and standard deviation of 1.14. In contrast, identifying symptoms of major insects/pest diseases was ranked 5th with the lowest mean value of 2.67 and a standard deviation of 1.23. Their plant protection issues by educating them on disease-resistant varieties and weather suitability of maize hybrid varieties for higher production through local agriculture programs broadcasted on a local FM channel and pamphlets.

Abstract

The carbon in soils related to the products of living organisms is noted as "soil organic carbon" (SOC). Soil is the largest terrestrial carbon sink, containing 2 to 3 times more carbon than the atmosphere and plants, respectively. The objective of this review is to assess and quantify SOC in Ethiopia across main land-use categories, as well as to identify critical gaps and priorities in SOC research and development. The existing literature search using research gateways, Google Scholar, and associated published and unpublished sources was employed as the methodological technique for this review. Previous authors have attempted to analyze and synthesize research on SOC in Ethiopia under major land use types emphasizing on the selected parts of the region. This is a key gap that this review aims to solve. According to the assessment, anthropogenic activities have nearly depleted 45 percent of the country's total landmass at this time. Forest Land (FL) > Grazing Land (GL) > (Cultivated Land) CL was the variable pattern for SOC. The highest SOC content was found in the FL, whereas the lowest was found in the CL. As a result of this analysis and research findings, it can be concluded that minimizing C losses by restoration of vegetation on degraded lands will improve SOC storage in Ethiopia, benefiting farmers and mitigating the current climate change.

Abstract

An alternative method of treating hospital wastewater can use a microfiltration membrane, where the results showed that the disposal of oily wastewater reached 82.5%, BOD 90%, COD 85%, and total Coli up to 70%. In addition, it can remove particles from wastewater from 0.04 to 100 microns in size. The problem with using microfiltration membranes is the rapid occurrence of fouling/saturation on the surface of the microfiltration membrane, causing the wastewater treatment operation time to be short. The length of this treatment causes the problem of less amount of wastewater being treated and another problem, namely faster membrane replacement. This study aims to determine the performance of pretreatment of microfiltration membranes made of alum, silica sand, and activated carbon for parameters pH, BOD, COD, TSS, Ammonia, Fatty Oil, and Total Coliform. The results of the study were as follows: 1) the average quality of hospital wastewater was temperature 28.8°C, pH 7, BOD 79 mg/l, COD 167.05 mg/l, Total Suspended Solid 68 mg/l, Ammonia 4 mg/l, Phosphate 0.745 mg/l, Fatty Oil 1.64 mg/l, Coliform 2.200 MPN/100 ml. 2) Comparison analysis of the most effective materials on the parameters, for BOD Silica Sand 78.24%, COD 56.25% Silica Sand, Total Suspended Solids 83.42% Activated Carbon, Ammonia Silica Sand 56.49%, Phosphate 80.43 % Activated Carbon, Fat Oil is 80.43% Alum, Coliform is Microfiltration Membrane 40.91%.

Abstract

Salak or Salacca fruit is a seasonal fruit; in some cases, this fruit easy rotten due to a lack of handling during the harvesting process or wet or humid storage. This condition will promote much waste because the fruit cannot be eaten. To minimize the waste, the seed of salak fruit can be converted to biochar. This study aimed to determine the chemical properties of biochar derived from the seeds of salacca (Salacca zalacca). The biochar is produced by burning the seeds using a furnace with a temperature of 350°C and 450°C, then ground and sieved with a size of 355 micrometers carried out at the Research Center for Limnology and Water Resources. Chemical property analysis using X-Ray Fluorescence Spectrometer (XRF) at the Lampung Advanced Characterization Laboratory- BRIN. The results show that most composition is Potassium (K). Potassium (67-70%) is the most abundant element in Salacca seed biochar, followed by chlorine. Biochar burned at 350 °C has a potassium content of 70.25%, while biochar burned at 450 °C has a potassium content of 67.86%. Biochar burned at 350 °C has a chlorine content of 25.35%, while biochar burned at 450 °C has a chlorine content of 24.66%. The percentage of potassium and chlorine decreases as the temperature rises. Furthermore, the phosphorus (P) and calcium (Ca) content of biochar appear at biochar burned at 450 °C.
