Abstract
In order to study the strength and damage characteristics of surrounding rocks of the first high-level radioactive waste repository in Beishan, Gansu Province, China, uniaxial compression, uniaxial cyclic loading and unloading, and triaxial cyclic loading and unloading of deep granite at the depth of 450∼480m of BS15 borehole in Beishan preferred area were performmed on MTS815 rock mechanics experimental equipment and acoustic emission monitoring system. The test results show that: (1) the cyclic loading and unloading process causes continuous damage in the specimen, and the peak stress and elasticity of granite under uniaxial cyclic loading and unloading decrease by 8.10% and 5.01% respectively,compared with the uniaxial loading test; (2) the confining pressure effect restrains the formation of internal damage in the rock, comparing to uniaxial cyclic loading and unloading, peak stress and modulus of elasticity under triaxial loading and unloading increased by 42.11% and 13.80%. (3) under different stress paths, the number of cyclic loading and unloading increased, the damage variable increased, and the damage degree of rock increased. The damage evolution rate under triaxial condition is slower than that under uniaxial condition, and the damage evolution process in yield and post-peak stage is less severe than that under uniaxial condition.

Abstract
The efficiency of the operation and maintenance for transmission lines can be greatly enhanced with the help of UAV. However, the images of the transmission line component collected by UAV could be spoiled due to the incorrect operations of the controllers, which causes the defects of the transmission line component couldn’t be diagnosed accurately. A visual inspection algorithm for the UAV based on the sensing of the tower components is proposed which uses a parallel network structure and can be applied on embedded devices, which based on Faster R-CNN target recognition framework and the ZFNet. Thus, the classification and posture of the component can be acquired. The UAV’s pose and position can be adjusted by the distance sensing model and components’ posture. Results show that the maximum mAP (mean Average Precision) of component recognition and posture perception are 0.95 and 0.91, respectively. Additionally, the posture of the UAV can be adjusted effectively and optimum images of the component can be obtained.

Published: November 2019

Abstract
The objective of this study was to evaluate the thermal stability of isocyanate as particleboard adhesives by means of TGA (thermogravimetric analysis). In this study, thermal properties particularly thermal stability of isocyanate-water/wood system was studied up to a temperature of 500 ºC using thermal analyzer (Mettler Toledo). When isocyanate was used as the binder in particleboard system; the reactive –NCO group reacted with water (because wood is a hygroscopic material and contains free and bound water) and also with the –OH group from wood. The isocyanate was H3M purchased from PT. Polichemie Asia Pacific and the wood particle was Eucalyptus sp. taken from PT. Toba Pulp Lestari. About 10 mg of the mixture either isocyanate with water or wood in various weight ratios were scanned at two different heating rates (slow and fast; 2.5 and 20 °C/min, respectively) with a temperature range from 25 to 500 °C. Results of this study indicate there were more resistant segments to heat in the mixture of isocyanate and water shown from the residual weights about 61-71% compared to in the mixture of isocyanate and wood particle (only 54-62%). Furthermore, there were fewer steps to degrade in the mixture of isocyanate and water shown from the number of peak temperatures about 1-2 peaks than that in the mixture of isocyanate and wood particle (2-4 peaks). New evidence also emerges that isocyanate reacted with water first shown from the weight loss from the low temperature in the mixture of isocyanate and wood particle.

Published: November 2019

Abstract
The development of low temperature tolerant rice varieties is needed to increase national rice productivity. Crosses and selection are the stages of the activity of developing low temperature tolerant plants. The effectiveness of selection depends very much on the action of the genes that control the selection character. Epistatic gene action will inhibit the progress of selection on self-pollinating crops such as rice. The purpose of this study was to estimate the gene action of the character of rice growth at low temperature stresses, and predict whether the growth character was controlled by the action of additive genes or by the action of epistasis genes. The research was conducted from July 2017-March 2018 at Brastagi Experimental Farm, Karo District, altitude 1340 meters above sea level with average temperature of 19 °C. The genetic material used was 191 F2 plants from the crossing of Situbagendit x Red Sigambiri and each 10 parents. The results showed that the character of plant height, panicle exsertion, age of flowering, and production had a middle value that varied with heritability values from low to high. The action of duplicate epistasis additive genes occurs in the character of generative phase plant height and flowering age while the character of plant height in germination phase, panicle exsertion and production is governed by the action of complementary epistasis genes. The characters observed have a pattern of distribution that is continuous and controlled by many genes.

Abstract
Rural development based on local resources utilization has been promoted as a strategy to achieve people prosperity in Indonesia. Although many studies have found that resource-based strategy is no longer relevant nowadays, for many areas this is still considered an appropriate approach. In order to examine the significance, we conducted a study in Sumba Barat Daya District of East Nusa Tenggara, focussing on coffee as one of the most abundant products in the region. Utilizing a socio-ecological approach, we collected data and information to depict the dynamics of coffee-based activities. A detailed study in Kadi Roma Village of Sumba Barat Daya on coffee ecosystem contribution to local community revealed that despite traditionally managed, coffee plays a significant role socially and economically. As a source of income to almost 17,000 smallholder farmers in Sumba Barat Daya, it can be concluded that coffee can become a gateway to attain successful rural development program. It also provides various opportunities for the community to participate which requires supportive innovation ecosystem to be established systematically by relevant local institutions, including include local government.

Published: November 2019

Abstract
Implementation of appropriate technology is recognized as one of the significant approaches for community empowerment. The principle of localities embedded in defined appropriateness of technology as “people mattered” has always been challenged when it is applied. This paper discussed the findings from an action-research work in the traditional coffee community in Sumba Barat Daya – East Nusa Tenggara. Coffee cultivation, post-harvest handling, processing to ground coffee, are tradition practiced to fulfill their need. The tradition is in the contest when there is a demand from the modern market requiring an increase of quality and productivity. The result of this study showed that to empower community it requires integration of technology appropriateness which is economically profitable and socially acceptable, and to ensure sustainability, maintenance of induced knowledge and practices should be strengthened by local institutional establishment based on social capital.
