Abstract
Siger rice is the Lampung term of Beras Singkong Segar which is artificial rice made from cassava. Siger rice is made from cassava which contains high amylose. The amylose comes out from the granules to bind water during the cooking and easily release the water and then the rice becomes hard and chewy. Therefore, Siger rice will be made from waxy cassava having no amylose to produce soft Siger rice after being cold. This research aimed to investigate the effects of Siger rice from waxy cassava on oligosaccharide levels and blood chemical profiles in mice. The research was conducted in a complete randomized block design with four replications. Siger rice was made from waxy cassava using a single screw extruder. The results showed that Siger rice has characteristics of white color, slightly cassava flavored, containing water (9.81%), ash (0.47%), fat (0.90%), protein (2.13%), crude fiber (4.79%), carbohydrates (81.90%), and glycemic index 30. The processing of waxy cassava into Siger rice can reduce levels of raffinose, stachyose, verbascose, and oligosaccharides 81.44, 92.09, 79.27, and 83.99%, respectively. Giving Siger rice to mice for 28 days had no negative effects on erythrocyte, hemoglobin, leukocyte, and hematocrit of mice.

Abstract
Physics computing can be used to help to solve complex dynamic equations, both translation and rotation. The purpose of this study was to obtain differences in the dynamics of the tippe top with and without friction moving on inner surface of a cylindrical with varying initial state based of Routhian Reduction. The equation of tippe top in flat fields with and without friction has been reduced by the Routhian reduction method with the Poincare equation with computational in the previous research, and computation has also been carried out in the search for numerical solutions to the dynamics of tippe top with friction in the Maple program. In this study the reduction used is a Routhian reduction, so that the equation used in determining the equations of tippe top motion with and without friction that moves in a curved plane in the form of a cylindrical surface with varying initial state based on maple is Poincaré’s equation based on Routhian reduction with and without friction. The effect of friction can be seen clearly through the dynamics and graph equations in the return top. This method can reduce the equation of backward motion with and without friction that moves on the surface of the cylinder clearly in the form of a set of differential equations. This research can be continued by solving the dynamic equations of the tippe top in other curved fields such as the torus and ball. The findings of this study are dynamic equations and graphs of friction with and without friction equations that move in curved fields in the inner of surfaces in cylinders with varying initial state based on maple.

AbstractPrevious research provided evidence that cognitive ability is one of the learning outcomes that students need to achieve. The purpose of this study was to analyze gender gap in cognitive abilities between male students and female students in learning of simple harmonic motion. The number of students involved in this research consisted of 14 male students and 22 female students with an age range of 15-17. The instrument employed in this study was a cognitive ability test with ten questions compiled based on Bloom’s taxonomy and was analyzed with the Rasch model. Cognitive ability which was measured included the ability to remember, understand, apply, and analyze. The data obtained were analyzed using person reliability, item reliability, Wright map, person measure, DIF and t-test. The results showed that there was no significant difference between male and female students’ cognitive ability. Therefore, the study indicated that there was no gender gap in students’ cognitive ability after attending physics class. However, students had poor cognitive ability, so educators need to design a simple harmonic motion learning process that is able to improve students’ cognitive ability.

Abstract
Low reading interest in high school students and the use of information and communication technology (ICT) are still not well integrated into learning. This is due to the lack of interesting biology textbooks and students’ habits in using gadgets for entertainment such as social media and games. For this reason, a solution to these problems is the development of pop-up books and virtual reality (VR) videos. This research uses the Research and Development method adapted from Borg and Gall by involving media and content experts for feasibility testing. The pop-up book and VR video evaluation were then carried out, the results showed feasibility without revision of 67% and some product revision suggestions. The results also showed the product responses to habits of mind (HoM) which included in the excellent category (3.7) from 100 students and 30 teachers even though preliminary test with a sample of high school graduates was still in the good category (3.2). Also, aspects of creative thinking are best between self-regulation and critical thinking. So, the implications of this research are pop-up book and VR videos are suitable as learning media also very good for improving students’ ha bits of mind.

Your money or your life? The carbon-development paradox
Authors: Steinberger Julia K , Lamb William F , Sakai Marco 
Published: March 2020

Abstract
The relationship between human health and well-being, energy use and carbon emissions is a foremost concern in sustainable development. If past advances in well-being have been accomplished only through increases in energy use, there may be significant trade-offs between achieving universal human development and mitigating climate change. We test the explanatory power of economic, dietary and modern energy factors in accounting for past improvements in life expectancy, using a simple novel method, functional dynamic decomposition. We elucidate the paradox that a strong correlation between emissions and human development at one point in time does not imply that their dynamics are coupled in the long term. Increases in primary energy and carbon emissions can account for only a quarter of improvements in life expectancy, but are closely tied to growth in income. Facing this carbon-development paradox requires prioritizing human well-being over economic growth.

Published: March 2020

Abstract
Over the years, the excessive use of agro-chemicals (pesticides and fertilizers) have adverse effect on the soil health and lead to declining of crop yields and quality of products. The shredding of twigs will provide an alternative for the use of agro-chemicals. For this to happen, the twigs will first be shredded into small bits making it ready for transportation and further processing. This necessitated the development of a shredder machine. The machine consists of three-phase electric motor, bearings, structural frame, cutters, hopper, shredding unit, discharge chute, belt drive and shaft. Four cutters are mounted on the shaft, which rotate by a belt drive. The power from the electric motor is transmitted to the cutter shaft through a belt drive. Cut is made inside the shredding unit due to the effect of tensile, friction and impact effect in shredding process. The twigs get shredded and the small bits are collected at the discharge chute of the shredder. The performance of the machine was evaluated and test results showed that there was a correlation between the weight of the shredded twigs and the shredding time. The shredding operation was done at 4 different time intervals (4 minutes, 8 minutes, 12 minutes and 16 minutes) with the same weight of twigs (40 kg) and the weight of small bits of twigs collected increases with time. The machine is user friendly and recommended for farmers and medium scale entrepreneurs.

Published: March 2020

Abstract
Analysis of input-output was done to investigate energy utilization pattern and efficiency in selected poultry farms in Kwara State, Nigeria. The poultry farms used for the study were grouped into three as group I (small), II (medium) and III (large) respectively based on number of birds. Energy used in chemicals, chicks, electricity feed, fuel, labour, and wood shaving as inputs and eggs, poultry meat and litter as outputs were determined. The result has shown that that diesel and feed accounted for the biggest proportion of all energy inputs in the farms. Energy consumption of the farms was found to be 28006.41, 26450.19 and 21894.39 MJ (1000 bird)−1, respectively. The energy output was 179766.54, 193670.10 and 223307.50 MJ, respectively (1000 bird)−1. Impacts of renewable and indirect sources of energy were greater than that of nonrenewable and direct energy. The rate of return to the scale was estimated at -0.04, suggesting that a 1% rise in each of the power inputs would result in a 0.04% reduction in the production. R2 was found to be 0.81 for the estimated model. Therefore, energy inputs (independent variables) can capture about 81% of layer yield variations in the poultry farms.

Abstract
Tomato (Solanum lycopersicum L.) is a vegetable crop reported as one of the most popular crops in the world. Producing tomatoes in many developing African countries is plagued with numerous postharvest challenges. Handling and packaging of harvested tomatoes is one of the main challenges faced in Africa. Packaging provides a means of ensuring safe delivery of a product to the ultimate user in a sound condition, at a minimum overall cost. In order to reduce post-harvest losses resulting from packaging and transportation of fresh tomato fruits, an alternative tomato-packaging container using Acrilonitrile-Butadiene-Styrene (ABS) plastic sheet was developed. The drawing was produced using automated computer aided design (AUTO-CAD). The drawing was simulated using 3-dimensional solid works software. The Finite Element Analysis (FEA) was run on the software to determine the tolerable stresses on the base and handles, drop test, buckling test and stack test. Also, design calculations were done for aerodynamics requirement, heat stress, container thickness, packaging ventilations and ergonomics. The container was developed using vacuum forming method from ABS sheet. A compression test was carried out in the strength of materials laboratory. Results revealed that the packaging container can accommodate a maximum load of 0.903 kN, implying that 3 containers when filled with fresh tomato fruits can be stacked on one another. The developed tomato-packaging container is collapsible and easy to maintain by cleaning with water. Ultimately, the tendency of the plastic packaging container to be stacked on top of one another makes it better than the conventional baskets currently used for packaging and transporting fresh tomato fruits.
