Abstract

Reinforced concrete shear wall (RC wall) is an important element in tall buildings, which provides strength and stiffness against lateral loadings, e.g. earthquake and wind. Numerous researches have been conducted to study its nonlinear behavior via microscopic and macroscopic model. The later approach is currently being widely explored since it has many advantages compared to the preceding models. A well-known macroscopic model, namely Shear-Flexure-Interaction Multiple-Vertical-Line-Elements-Model (SFI-MVLEM) in the open source platform Open Sees, is capable of simulating the coupled nonlinear shear-flexure interaction response in the RC wall. This paper presents an evaluation to the applicability of SFI-MVLEM model to predict the coupled nonlinear shear-flexure behavior of RC wall specimens compared to experimental results in available literature. The analysis results show that the model is able to predict the behavior of RC wall considerably accurate in terms of hysteretic curves, cracking patterns, and contributions of shear and flexural displacement to total displacement.

Abstract

The idea of governance has successfully gained its popularity in Indonesia. The government, private enterprises and society welcome and embrace the idea of governance as a final solution to maintain development. In this paper, it is argued that the implementation of governance can not guarantee the fulfillment of society’s interest due to the existence of unequal power relation embedded in country’s political environment. The concept of Governance, moreover, can be claimed as an imperialist instrument since this concept has strong interconnection with neo liberal agenda. Indeed, Governance as new imperialism will reduce nationalism. Key words: Governance, Hegemony, Nationalism, Imperialism.

Abstract

State Law No. 12/92 on agricultural systems for food crops stated that good quality seeds is seeds of correct and pure variety with high genetic, physiological and physical qualities, and in accordance with the quality standard of its class. The demand for groundnut seeds were almost entirely fulfilled by informal seed supply, which may come from a traditional system (farmers use their own seeds), buying from agricultural shops that process their own harvested pods into seeds, or buying from informal seed growers. Whilst the certified seeds produced by official seed growers is very limited in amount and supplys only a small portion of the total national seed demand. Under such condition, selection for seed quality is mainly based on the physical seed condition, such as seed size, brightness of seed coat color, and maturity of seeds. In other words, farmers prefer to select sound mature kernels and reject the shriveled kernels. Research results, however, indicated that plants generated from shriveled kernels were not significantly different to those generated from pithy kernels in term of growth and pod yield. Given the high cost and limited stocks of seed during the high planting season, it is advisable seed sorting process is not too tight and the use of wrinkled seeds for planting is prioritized. When there are overstock seeds, it is suggested to keep the sound or pithy seeds or to consume these seeds for food safety issue. This is because research results showed that shriveled seeds are more susceptible to Aspergillus flavus infection and aflatoxin contamination than the pithy seeds.

Abstract

The substance is very toxic, which may cause health problem when consumed by human or by animal. of the twelve aflatoxin members, the B1-aflatoxin was reported as the most prevalence in Indonesia, and it was also the most toxic. Therefore, B1-aflatoxin was used as a criterion for the maximum tolerable limit of aflatoxin content in food and feed stuff. Aflatoxin B1 contamination was reported on groundnut grains sold in the retail traditional markets throughout Indonesia. The contaminated grains were noted derived from the nationally produced as well as from the imported ones. The aflatoxin contamination increased as the grain of groundnut reached the final retail markets destination. Contaminated grain processed into various food retained the aflatoxin in a toxic form. The negative effect on health from consuming food contaminated by aflatoxin must be minimized. The government of Indonesia had established food safety regulation regarding aflatoxin contamination, but prevention through the proper cultural practices and post harvest handling of groundnut, were equally important measure.
