The Modifying Factor of Lead Exposure Time with Blood Lead Levels on Adulterated Paint Worker
Authors: Lestari Diah , Purwanti Angki 
Published: May 2020

The modifying factor for exposure time for paint workers who work more than 8 hours / day have abnormal blood lead levels> 10 Î¼g / dl. Lead exposure to paint workers occurs when mixing paints, mostly through air, skin, through food and drinks. The longer the work, the more the amount of lead exposure received, although the amount of lead absorbed by the body is only small, this metal turns out to be very dangerous and can cause health problems due to the buildup of lead in the body. The presence of lead (Pb) in the blood can cause severe and dangerous effects including interfering with the hematopoietic system, a long exposure can disrupt the gastrointestinal system, central nervous system, immune system, kidneys. The purpose of this research was to determine the relationship and closeness of the relationship between the modification factors of exposure time with blood lead levels of adulterated paint workers in the area of East Jakarta. The research method uses primary data through an analytic observational cross-sectional design approach. Sampling is done by non-probability sampling with consecutive sampling techniques. The correlation test used was the Spearman test with a confidence level of 95%. The results of the research found that the average exposure time of adulterated paint workers was 48.9 hours/week exceeding the permissible work time, and the exposure time >40 hours/week was 77.5% of the number of respondents. The average blood lead level was 0.15 mg/L, with the highest blood lead level 0.45 mg/L and workers with exposure times> 40 hours/week obtained blood lead levels exceeding the safe reference limit (40 mg/L) of 19.4%. The conclusion is that there is a significant relationship between duration of exposure and lead level of adulterated paint workers (p-value = 0.029) and shows the moderate closeness of the relationship with the direction of a positive relationship. The value of r = 0.346, means that the longer the person is exposed to lead, the higher the level of lead in the blood of adulterated paint workers. The discussion of modification factors of exposure time in adulterated paint workers can influence lead exposure continuously, in the long term, absorption of lead in the body 99% which is bound to erythrocytes will accumulate in the blood, then it is distributed into the blood which is 90% binding to cells red blood cells (erythrocytes), and the rest are bound to blood plasma. Once absorbed, the lead will be stored in the blood for 35 days. For 8 hours, a worker can absorb up to 400 Î¼g and add 20 - 30 Î¼g / day from food, drinks, and air. The presence of lead in blood represents a reflection of the dynamic continuity between exposure, absorption, distribution, and excretion, so that it is one indicator to know and follow ongoing exposure.

Mass propagation technology through somatic embryogenesis has become an alternative for producing sugarcane seedlings rapidly.Application of proper plant growth regulator and concentration contribute to support somatic embryogenesis development. This study applied the combination of liquid and solid culture during proliferation stage to promote cell dispersion of embryogenic callus, rapid embryo somatic production, and improve regeneration potency of somatic embryo. Application of 2,4-D and coconut water during proliferation may expected as proper combination for accelerating somatic embryo development and regeneration.Development of somatic embryogenesis in sugarcane var. Bululawang during proliferation were described in this study. Embryogenic callusfrom induction media were transferred to proliferation media containing MS Basal + vitamin supplemented with sucrose different level of 2,4-D (1 mgl-1, 2 mgl-1, 3 mgl-1, 4 mgl-1 ) and coconut water (0% and 5%).Result showed that low concentration of 2,4-D induced optimum somatic embryogenesis development in proliferation and regeneration. Concentration of single 2,4-D 1 mgl-1 without coconut water induced rapid development of scutelar and coleoptilarduring proliferation and resulted in better shoot regeneration. In other way, 4 mgl-1 of 2,4-D concentration affected to inhibit scutelar and coloeptilar formed as the result of failure callus differentiation.

This study was done on two-month and six-month sugarcane of PT. Perkebunan Nusantara VII Cinta Manis District. The research location is located in Ketiau Village, Lubuk Keliat District, Ogan Ilir Regency, South Sumatra. The study was conducted from July to December 2018. Insects that came to flowering plants were collected by using fitfall traps, nets, and direct capture of insects that came. The results showed that the age of sugarcane affected the diversity of Entomophage and Phytophage insect species that came to the flowering plants. At 2-moth-old sugar cane plantations were found 42 species (388 individuals) and 6-month-old sugarcane plantations were found 41 species (284 individuals). The diversity of Phytophage and Entomophage species that came to flowering plants in the 2-month-old sugarcane plantations was almost the same as in the 6-month-old sugarcane plantations. Phytopage species diversity index values were 2,826 and 2,548, while Entomophage were 2,564 and 2,867.
Integration and the Diplomatic Crisis: Current Realities of the GCC
Authors: Shkvarya L. V. 
Published: May 2020

The article analyzes the integration process in the Gulf Cooperation Council group countries (GCC), which was founded in 1981. Regional economic integration in the GCC has passed through the several traditional stages: the Free trade zone, the Customs Union and the Common market. Certain exceptions remain in the GCC integration, but the countries aim to create a full economic Union by 2025. Currently, the GCC is one of the most advanced and successful integration associations in developing countries. However, the GCC is the only truly functioning integration bloc in the MENA region. The author's analysis confirms that the share of intraregional trade is growing in the GCC, but this share is less high than in other integration blocs. The author emphasizes that the GCC countries have significant success in the world market of goods and capital. The GCC trade turnover is growing steadily, although it depends on fluctuations in world oil prices. The GCC region attracts a lot of foreign investment and technology. This allows them to continue to diversify their national economies. The level and quality of life in the GCC is improving. These and other achievements are largely the result of regional economic integration and cooperation between countries in various areas on the world and regional markets. At the same time, the GCC is one of the most strategically important regions in the world economy and politics. Economic and political processes are influenced by many factors, both internal and external. Therefore, there are many contradictions in the GCC, and sometimes crisis situations are formed. One of them is the current "diplomatic crisis". It began in 2017 and has so far created numerous problems in the region and in the Arab world as a whole. It also has a negative impact on the development and deepening of integration processes. The author analyzed statistical data for 2009-2018 and justified the conclusion that the "diplomatic crisis" damages intraregional trade, reduces the dynamics of macroeconomic indicators, and worsens the position of the GCC countries in the world market of goods and capital. It also creates difficulties for citizens of GCC countries and companies that operate in the region. Now GCC countries should develop a mechanism to de-escalate the crisis, as this is in the economic and political interests of all participants and the Middle East as a whole. The relevance of the research is due to the need to analyze regional economic integration processes in the subregion in the context of growing global instability. The research makes a significant contribution to understanding the nature and features of integration processes in the Middle East.
