Genetic variations of EMS-induced chili peppers (Capsicum annuum) cv. Gelora generate geminivirus resistant mutant lines
Authors: Manzila I , Priyatno T P 
Published: May 2020

AbstractA mutation breeding program was conducted to improve chili pepper (Capsicum annuum) resistance to Geminivirus caused byPepper yellow leaf curl virus(PepYLCV). The disease can cause significant yield losses on chili pepper. This study was conducted to enhance genetic variation in pepper cv. Gelora using ethyl methanesulphonate (EMS) to obtain mutant lines resistant to PepYLCV. Exposure to an EMS solution of 0.5% (v/v) for 30 minutes was used for mutagenizing shoot tips to produce the first population (M1). After the treatment, shoot tips were cultured on MS medium to regenerate planlets that were subsequently acclimatized to produce M2population. A set of 2,955 mutant lines (M2) were screened in a greenhouse by inoculating PepYLCV isolate Segunung using white flies (Bemisia tabaci) as the virus vector. Six weeks after inoculation, the M2population was examined for symptoms of Geminivirus and was verified for the presence of PepYLCV infection by PCR using specific primer. The greenhouse assay successfully selected 47 lines (1.6%) of M2mutant population that showed no symptoms and no infection to PepYLCV compared to Gelora and Tanjung-2 varieties. Subsequent field test of M3mutant lines in Geminivirus endemic area in Lembang, West Bandung, revealed that 15 out of 47 lines showed high resistance to PepYLCV and have good agronomic characters including yield components. A set of primers corresponding to the PepYLCV infection which produced 678 bp in size indicated its good amplification in the susceptible mutant lines, confirming the PepYLCV resistance of 15 selected mutant lines. The resistant mutants were immune to PepYLCV and had potential to be released as improved varieties in the future.

Published: May 2020

Abstract
Khao Kai Noi rice is considered as an elite quality landrace in Laos, which has led to its germplasm conservation in the Laos National Genebank. As happens with other germplasm collections, a manageable yet representative sub collection has become an essential element for researchers and breeders to simplify many activities, including those related to crop improvement, phenotype-genotype correlation and determination of diversity hotspots. In this study, 109 accessions were used as a test collection for core collection development to determine the feasibility of collection reduction in a closely related rice group. Three core collections were developed by two established methodologies and evaluated by diversity indexes, allele retention, phylogenetic distribution and geographical location. Based on SSR molecular markers and PowerCore, a reduction to 24 accessions was achieved with the conservation of complete genetic diversity. A K-means based on reduction to 24 accessions rendered slightly lesser results while based on 12 accessions resulted in a 17% diversity loss. These core collections may be useful for genebank management, research and breeding activities in the future. Also, they may as well serve to estimate core collection development behavior in other landraces and cultivars, which is fundamental in genetic resources management and utilization.

Abstract
Agriculture faces enormous challenges for providing sufficient food, feed and fuel raw materials for a growing global population. In the case of food, for instance, global food production must always increase to meet the projection of continuously increase of global food demand. The future challenges of food supply and demand can be addressed by diversification of food sources, introducing high yielding cultivars and improving culture techniques. Food sources can be diversified by collection and evaluation of genetic resources for nutritive values. In contrast, new varieties can be developed through breeding activities that also require genetic resource as genetic material. Genetic resources spread around the world, and to optimally utilize, genetic resource must be explored and conserved both by in situ and ex situ approaches. The genetic resource exploration through missions requires proper preparation including human resources, logistics and time allocations. Universitas Gadjah Mada (UGM) as a higher education institution has three big university missions, i.e. education, research and community service through student involvement. These three missions through student involvement have been applied to conduct the genetics resource exploration and ex situ conservation. The course of genetic resource collection and management has been introduced at different faculties, and because community service at the rural area for two-month times is compulsory for the student, UGM makes use of student to carry out genetic resource exploration and collection. The student must collect the passport data for the genetic resources and send the data to the Agriculture Innovation Center (AIC). In case that seed of genetic material can be found, student must collect also seeds and send to AIC for ex situ conservation. Based on UGM experience, ex situ conservation, especially seed genebank, faced sustainability problem due to insufficient human and funding resources. UGM integrates some approaches such as crop focusing, networking, student involvement in the characterization and evaluation, and breeding activities to solve such problems.

Abstract
This study aims to determine the effect of the application of Trichoderma sp. Fungi. and Pseudomonas fluorescens bacteria as biofertilizer agents and P fertilizer doses as well as interactions between microbial biofertilizer agents and P fertilizer doses on vegetative growth and early appearance of red chilli flower flowers to the initial flowering period. This greenhouse experiment was arranged factorially in a completely randomized design. The first factor was the application of microbial biofertilizer agents consisting of no microbes, Trichoderma sp., And P. fluorescens, while the second factor was the dosage of P fertilizer per 5,000 g of soil planting medium consisting of 0, 0.5, and 1.0 g SP-36. Nine combinations of treatments repeated three times to obtain 27 experimental units. The variables observed were plant height, stem diameter, leaf area, wet weight and stover dry weight at 42 days after planting (DAP) and the beginning of flower emergence. The data were analyzed by 5% ANOVA followed by a 5% HSD Test to determine the difference in influence between treatments. The results showed a very significant interaction effect between the application of microbial agents and the dose of phosphate fertilizer to height, stem diameter, leaf area, wet weight and dry weight of stover and the initial flowering time at 42 DAP. The application of P. fluorescens bacteria as a biofertilizer agent combined with 0.5 g SP-36 fertilizer dose per 5,000 g of planting media showed the highest growth effect of red chili plants at age 42 DAP in terms of plant height, stem diameter, leaf area, stover wet weight, stover dry weight, and earlier flower appearance.

Abstract
Indonesia is one country that has many active volcanoes, and it can have a high potential for earthquakes due to volcanic activity. Central Java is an area that has an active volcano, the Mount Slamet. Various kinds of earthquake signals, earthquake strength, and frequency are recorded using a seismogram. The process of recognizing seismic signal patterns using short-wave transformations has a higher chance of success. Several types of earthquakes that have occurred on the Mount Slamet. There are three types of earthquake data tested, Shallow Volcanic Earthquakes (VB), Gust, and Tremors. This study aims to identify the type of earthquake vibration signals recorded on the seismograph. Earthquake image processing system consists of several parts. The image is normalized to get the image in the time domain. Then the image is processed with two processes to determine the characteristics of the earthquake. The Fast Fourier Transform process is used to determine the strength of earthquake signals based on the frequency. The quantization process is used to take samples of each data in the time domain. In this study, the method used for identification is pattern recognition and decision trees. The identification system can recognize signals that are approached using the Root Mean Square, Average Power Spectrum, and statistical features. The results of tests carried out obtain 100% accuracy of each method.

Abstract
Identity Theft Resource Centre revealed there were 668 cases of cybercrime occurring with a total number of lost data 22,408,258 started from January to July 2018. It indicates that there was a vulnerability in the defences from attacks carried out through the internet. Thus, the world of information systems should also be accompanied by a high level of security. The stages of system development were started from the analysis of system requirements, the design of the UML, implementation, and testing. The testing process into two-phase. Firstly, system output testing in the form of stego image with various criteria, namely imperceptible, fidelity, recovery, robustness, and histogram. Secondly, system feasibility testing using the SUS method. Based on the results, it revealed that the merging of the blowfish cryptographic method and the end of file steganography was not very effective because, based on the output testing with robustness criteria; it was proven that the message inserted into the image was damaged during extraction. The changes in the size of the original cover with the resulted stego image had increased file size with a ratio of 1: 5.5, meaning that each created stego image was five times the size of the original image.

Published: May 2020

Abstract
The main function of a pump is moving fluid through a pipe from one place to another. The dominant characteristic of a centrifugal pump is its output torque and power. Torque is obtained from the measurement of force using a dynamometer, then the result is multiplied by the moment measuring arm (L). Dynamometers are used to measure weight, which is influenced by gravity, which is mass (m) multiplied by the acceleration of gravity (g). The design concept of this equipment consists of a free moving motor body, dynamometer layout, safety pump, and fluid flow pipe. The pump is designed to be equipped with laboratory scale test kits and sketches of images made using ZWcad. The product design test is carried out using a comparison of the torque value to the centrifugal pump both in filled and unfilled condition. The difference in the value of the output torque is not too far from the theoretical calculation, so this torque measuring instrument is worth using.

Abstract
The surface of the evaporator glass in the seawater desalination process by utilizing solar energy as the main energy source is a phenomenon that has been widely studied and developed in order to get increased performance efficiency to produce fresh water. The heat energy from the sun will enter through the surface of the evaporator glass and absorbed by water inside the evaporator, while the evaporator wall is insulated using aluminium foil with a thickness of 20 mm in the hope that the heat energy received will not be wasted around the environment. The process of evaporation of seawater begins when the water has reached the point of evaporation without pressure and occurs naturally. When seawater starts to evaporate, it can be calculated the amount of heat energy absorbed by the water until it reaches the point of evaporation, in order to determine the increase in performance and efficiency of the desalination process. Efforts to improve continue to be done if it is still possible to increase the efficiency and performance of desalination devices with various energy utilization methods. After testing, the highest solar intensity obtained on the test day reached 420.85 W/m2, and the lowest solar intensity on the second day was 96.89 W/m2. The highest evaporation heat transfer coefficient reaches 10.54 W/m2 °C and the lowest is 4.42 W/m2 °C. The highest convection heat transfer coefficient reaches 51.15 W/m2 °C and the lowest heat conversion coefficient is 15.28 W/m2 °C. The total absorbed energy reaches 6.26 kW and the lowest absorbed energy reaches 1.37 kW. Energy efficiency reaching 85% and the lowest energy efficiency is 35%.

Published: May 2020

Abstract
With the development of MEMS (Micro-electro-mechanical Systems) techniques, research interest has deepened in micro piezoelectric harvesting device, which can supply electrical power for wireless sensors from ambient vibration. This paper proposes a nonlinear analysis of a micro-scale PEH (piezoelectric energy harvester), which is modeled by a micro-cantilever plate with two layers and a tip mass attached to the free end. Considering size effect and nonlinear curvature, based on strain gradient and inextensible plate theory, nonlinear dynamic equations of the micro cantilever piezoelectric energy harvester with tip mass are established by virtue of the Hamilton’s principle. The maximum output voltage of piezoelectric energy harvester with different tip mass is calculated respectively using MATLAB software. Comparative analysis confirms that an increase of K (the mass ratio of the tip mass to piezoelectric plate) reduces the natural frequency of energy harvester and significantly enhances the nonlinear phenomenon. In addition, when the mass ratio K exceeds 1, obvious superharmonic resonance phenomena generates, which considerably improves the output voltage of the proposed PEH in a lower frequency band. This study proposes an approach to enhance the output performance of micro-cantilever plate energy harvesters and broaden the bandwidth of PEH to adapt low-frequency ambient vibration.

Abstract
A high definition (HD) map based motion plan and control method of autonomous vehicle on structured road is proposed in this paper. The system is designed in a multi-layer structure: a motion planner and a motion controller, furthermore, the motion planner is consisted of a global path planner and a local trajectory planner. The inputs of the global path planner are HD map, start and goal state, Dynamic Program (DP) is used to plan a global path that connect these two states based on the lane-level structures and traffic rules extracted from HD map. The inputs of local motion planner are the planned global path, current host vehicle state and the surrounding dynamic object information, several candidate trajectories are generated in Frenet frame, and then the optimal one is chosen by a multi-term cost function calculation. Taking the vehicle dynamics under high speed into consideration, Model Predictive Control (MPC) is used in motion controller to track the planned target trajectory. Results of the conducted simulation tests show that the designed motion plan and control method works well in velocity keeping, vehicle following, stopping and going, and vehicle passing scenarios.
