Abstract

Mung bean farming activities are often faced with low production by farmers. Farmers face a variety of problems, including annual increases in the price of labour, seeds, fertilisers, pesticides and output prices. Thus, improvements at the farm level and price stability are required. This helps to ensure increased income and profits for farmers, and will also encourage farmers to be more intensive in managing their farms. This study aims to: 1). Identify farmers' income from mung bean farming, 2). Knowing the relative profit of farmers from mung bean farming and 3). Knowing the break-even point obtained by farmers from mung bean farming in the Weoe Village Transmigration Area, Wewiku District, Malacca Regency. This research uses a survey method, the data used are primary data and secondary data. The research location in the Weoe Village Transmigration Area, Wewiku Sub-district, Malacca Regency was determined purposively, based on the potential for production development and the area of mung bean land. Samples were taken by simple random sampling of 60 respondents. The analysis method used income analysis, R/C ratio and Break Even Point. The results showed that, 1) the income obtained from mung bean farming was Rp 134,486,076 or Rp 5,655,428, -per hectare. 2) the relative profit obtained is 3.07, which means that the farm is economically profitable so it is feasible to develop, 3) the break-even point of production is 73.77 kg, meaning that when the production amount is 73.77 kg the mung bean farm is at the break-even point or the amount of production returns capital so that production of 875 kg/ha has exceeded the break-even point by 11 times in other words, it is profitable. While the price break-even point is Rp. 3,124/kg, meaning that when the selling price of peanuts is Rp. 3,124/kg, farmers have recovered their capital. With an average selling price of Rp. 14,683/kg, which exceeds the break-even point by more than 4 times, mung bean farming is in a profitable position.

Abstract

The increasing plastic waste volume in Gorontalo City is not balanced by a good management system, making people choose to burn their waste in open space. Not only makes a bad scene, this burning emits dangerous gases such as CO2 that contributes to poor air quality and climate change. This study has developed an environmentally friendly incinerator with a stacked condenser system that emits less CO2 gas. This incinerator consists of three main components: a combustion zone, as the place where plastic waste is burned; a chimney, for the flowing of gas; and stacked condensors, for cooling and keeping the gas before emitting it out. We test the incinerator with and without condensors based on the CO2 emission from 20 minutes' burning of 1.5 kg of plastic waste. The results show that an incinerator with a stacked condensor system can significantly reduce CO2 gas emissions by 18.88% more than an incinerator without condensors. This implies that incinerator with stacked condensors can be an alternative way to reduce CO2 gas from open-space waste burning on a small scale.

Abstract

Stature (body height) is an important and useful anthropometric parameter for identification of an individual. Among the various parameters of identification, individual's stature is an inherent characteristic, the estimate of which is considered to be important in those cases where only fragmentary or mutilated remains of an unknown person are recovered. The objectives of this study were to determine sex differences among the participants from all the measured parameters (hand length, palm length and the lengths of the second, third, fourth and fifth digits), find the correlation between stature and all the measured hand dimensions and further establish linear regression equations, regression line graph and determine the accuracy rates (percentage) of the estimates by calculating the estimated stature from the actual stature. A total of 407 (181 males and 226 females) adolescent’s participants who were Fulani origin by both parents and grandparents attending the selected secondary schools and met all the inclusion criteria were selected and measured for each of the parameters. Stature was measured using stadiormeter and vernier caliper was used to measure the hand parameters. The data were analysed using IBM SPSS Statistics version 20. P < 0.05 was considered significant. All the parameters showed significant correlation with stature at P < 0.01. Hand length showed the highest correlation value (r = 0.668), while fifth digit length had the least correlation value (r = 0.527). This study shows that stature and hand dimensions are sexually dimorphic with male participants having higher values of the measured parameters than the female participants. linear regression equations were formed for each of the parameters. Hand dimensions are considered as good source for estimating stature in forensic practice amongFulani adolescents of Yola origin, Adamawa State of Nigeria.
