Abstract

Pesticides are toxic substances which have some negative impact on human health problems. Cholinesterase enzymes play a role in keeping the muscles, glands and nervous system working harmoniously. The high and low activity of cholinesterase enzyme is an indicator of the level of poisoning in the human body and can be used as an indication of the presence of pesticides in the blood. The purpose of this study was to analyse the relationship of pesticide exposure with cholinesterase levels in the blood of pesticide spraying workers at PT. Langkat Nusantara Kepong Gohor Lama. The research method used is Cross-Sectional at PT. Langkat Nusantara Kepong Gohor Lama with a total sample of 65 workers was obtained by Simple Random Sampling. Information was obtained through interviews with questionnaire aids and cholinesterase examination using a tintometer kit. Based on the results of the analysis using chi-square obtained exposure to pesticides associated with cholinesterase levels in the blood of pesticide sprayers. The result of this study shows that the level of cholinesterase is significantly related to the length of service (p = 0.004) and the use of Personal Protective Equipment (PPE) (p = 0.002). Suggestions for workers to be more obedient in using PPE in the workplace to minimize exposure to pesticides that enter the body, for companies to pay more attention to the feasibility of PPE that is replacing damaged PPE, make rules or sanctions if workers are negligent and do not use PPE that has been provided and workers with abnormal levels of cholinesterase should be moved temporarily to a minimum of chemical work and companies are advised to use environmentally friendly pesticides so as not to endanger workers, animals and non-targeted insects.

Abstract

Performance of Family Planning Field Officers can be seen by achieving the number of TFR, in accordance with the national target of 2.4. The total TFR of Sibolga city in 2016 was 2.6. Sibolga City is a city that consists of 4 districts and 17 villages. Sibolga City has 31 Family Planning Field Officers. The purpose of this study is to determine the performance of Family Planning Field Officers to reduce the total fertility rate. This type of research is qualitative with a phenomology approach. The results shows that the performance of Family Planning Field Officers in Population Control and Family Planning Department of Sibolga City PPKB Office is still not optimal. This is marked by the performance evaluation carried out and monitored only through social media chat groups, but the implementation of direct monitoring is still not good, there are gaps in report data in the field found by the difference in the number of Family Planning participants in the field with the number of Family Planning participants in Population Control and Family Planning Department Office, delays in sending reports, the number of human resources has exceeded the provisions but the TFR target has not been achieved, PLKB skills in counseling are still lacking, Population Control and Family Planning Department work discipline is still often violating things such as being late for work and leaving the workplace without a clear reason. This study recommends that Population Control and Family Planning Department conduct routine monitoring of Population Control and Family Planning Department in the Family Planning Health Center, provide training to PLKB in terms of counseling, give rewards to the districts with the lowest TFR, conduct scheduled outreach to the community regarding family planning programs in terms of reduction TFR number.

Abstract

Workers who are exposed to evaporated organic compound from printing in the long term will have the risk for subjective symptom of central nervous system disorder in which it is the main entrance to the body through inhalation process. Workers in the production unit will have the most dominant risk for it. The objective of the research was to analyze the influence of using respirator on subjective symptom of central nervous system disorder in worker who work at digital printing industry. The research used one group pretest-posttest design. The samples were workers, taken by using purposive sampling technique. Bivariate analysis used paired t-test at the significance level of 95% (α=0.05). The result of the research showed that p-value = 0.0001 (p<0.05) which indicated that there was significant difference in the scores of Q16 questionnaires between pre and post intervention. The result of Q16 questionnaire in Swedish version showed that 20 respondents (100%) had difficulty breathing and 20 respondents (100%) had headache at least once a week. In the post-intervention with using respirators in one month, there was no complaint anymore. Respirator is equipped with organic vapor cartridge which is able to absorb gas from contaminated air before it enters the workers’ respiratory system. Using respirator as a personal protective device influences the decrease in subjective symptom of central nervous system disorder in printing workers. Using filter, cartridge, or tube in respirator should be done accurately otherwise it will cause danger for the workers.

Abstract

The durability of interface bond was not sufficiently taken into consideration, and the research work in this field is scares and scattered. The interface bond usually practices dynamic shear stresses throughout its service life while ageing due to volatilization provide stiffness at the interface. In this investigation, an attempt has been made to assess the durability of the interface bond in terms of resistance to ageing under repeated shear stresses. Two types of tack coat (Rapid Curing cutback RC-70 and Cationic Medium setting emulsion CMS) and three application rates have been implemented in the preparation of two layers slab samples (base overlaid by binder, and binder overlaid by wearing) courses using roller compactor. Asphalt concrete core specimens were obtained from the roller compacted slab samples and subjected to long term ageing, then the specimens were subjected to 1200 repeated shear stress cycles. The accumulation of permanent deformation was monitored. Afterwards, the specimens were tested for interface shear strength at 20 °C. Control specimens were also tested for comparison. It was concluded that ageing reduces the total microstrain for RC-70 tack coat by (43.6, 25.6, and 29.5) % and (50, 51.3, and 30.2) % for (binder-base) and (wearing-binder) interfaces for the application rate of (0.15, 0.33, 0.5) l/m2 respectively. However, ageing reduces the total microstrain for CMS tack coat by (37, 35.5, and 40.3) % and (45.2 , 49, and 46.8) % for (binder-base) and (wearing-binder) interfaces for the application rate of (0.1, 0.23, 0.35) l/m2 respectively. Ageing increases the interface bond shear strength by a range of (8-27)% for various interfaces, tack coat type and application rates.
