Abstract:- Wood dust contained endotoxin LPS can cause respiratory tract inflammation, decreased lung function and pneumonitis. This study aims to analyze the effect of endotoxin levels to elevated levels of serum C-RP and a decrease in pulmonary function sawmill workers. Analytic observational research methodology to design a prospective longitudinal study.The study sample as many as 12 workers in the factory Sawmill MojoagungJombang.Data collection techniques with interviews, personal dust measurements, personal endotoxin measurements, blood sampling, and spirometry. C-RP serum and lung function were measured before and after work. The dependent variable in this study is the serum levels of C-RP blood and pulmonary function. While the independent variable is the level of personal endotoxin. Age, years of service, and the habit of smoking is a confounding variable. Result: The average age of 40 years, 21-year working period, 75% light smokers. After 8 hours the average levels of personal wood dust was 0.53 mg / m 3 and personal endotoxin levels by an average of 55.50 EU / m 3. Workers who have increased C-RP as much (41.67%), with an average of 0.1192 mg / L. Workers who experience a decrease in FVC as much (58.33%) and FEV 1 decline as much (75%). Test results using Multiple Regression, there is no influence of the personal endotoxin levels with elevated levels of serum C-RP and decreased lung function (p> 0.05). Conclusion: Endotoxin LPS in a sawmill dust does not affect the increased levels of C-RP blood serum and lung function decline in workers.

This study includes observations on the waste management system in the real estate area of southern Gresik, then sampling to test the water quality standards in laboratory waste Environmental Health Technique Bureau Surabaya, both questionnaires and interviews with the developers to conduct Focus Group Discussion with government, real estate developers and residents. Domestic sewage in the housing / real estate is mostly done using the direct method of wastewater discharged directly into the river or temporarily housed in local temporary disposal site. The results of laboratory tests on domestic wastewater generated housing average domestic wastewater is around the threshold set by Ministerial Decree Environment No. 112 of 2003 but exceeded the detection limit pollution. So it is still a potential source of contamination that could exceed the upper threshold value corresponding MOE decree. This could happen due to the potential for the development of housing for more habitable. The majority of the developers are not aware of the Environment Decree no. 112 of 2003. So that the disposal and management of industrial waste water is not in accordance with the prescribed rules.

In attempts to re-enable the river transport that is considered less desirable by users, a typical approach/an approach related to the types of river transport that people expect. In this research, four types of river transport are offered to the community which is expected to physically meet the criteria of the (Indonesian) National Transportation System. Analysis of the selected priority level using an approach of the AHP method to relative and absolute measurement was carried out. The results of the analysis find that people generally tend to expect the typical river transport with the following criteria: catamaran type, the entry/exit can be from the front and the rear, the sides of the ship are flexible and can be open or closed, passengers can stand up inside the vehicle, the ship can load bikes, and the lower position of the passengers is above the surface of the water. In terms of the fulfillment of the (Indonesian) National Transportation System criteria, safety is the most dominant criterion to be considered (18.87%), followed by the criterion of security (16.45%), the utilization criterion (12.49%), and the comfort criterion (11.53%). While the criteria for a low level of pollution and capacities are the lowest criteria that influence the selected choice.

The development of urban areas cause a variety of problems and challenges as a direct impact of the development conditions of the region, including in terms of planning adequate transportation system, which is able to meet the needs of urban population movements, not only in terms of the amount of means of transport, but also should pay attention to and improve performance of public transport services, strategies to improve the performance of public transport in satisfaction of public transport users, requires an understanding of the attitudes of public transport users, knowledge of user behavior will provide optimal results to improve the performance of public transport according to expectations and interests of public transport users. This study aims to investigate the performance of public transport services, knowing the satisfaction of public transport users in terms of aspects of interest or societal expectations, determine the effect of the level of satisfaction of public transport services on the performance of public transport. This research method is a method of qualitative research, data analysis is used to determine the performance of public transport use Importance Performance Analysis (IPA) and know the satisfaction of users of public transport using the Customer Satisfaction Index (CSI), to examine the effect of satisfaction on the performance of public transport using Structural Equation Modeling (SEM). The results showed that the performance of public transport remains low in providing services to the users of public transport. The main priority of the expectations or interests of public transport users to get treatment or improvement of public transport services is an indicator of accessibility, integration, capacity, smooth and fast, convenient, safety, easy, timely, orderly, efficient. Based on the calculation, the CSI value of 48.19% or 0.48 based on criteria CSI values were in the range from 0.35 to 0.50 (less satisfied) this means that the public transport user satisfaction index of the performance of public transport are less satisfied with the service transport general. Based on the results of SEM analysis of the influence of public transport user satisfaction (Y) on the performance of public transport (X) derived a mathematical equation Y = 0,873X + 0.022 indicates that the public transport user satisfaction has a positive and significant effect on the performance of public transport, any increase in public transport performance indicators it will also influence the increase in satisfaction of users of public transport.

The Job Shop scheduling problem is one of the hardest combinatorial optimisation problems in various industrial environments. It consists of several jobs each with one or more operations, to be allocated to a set of machines with a view to minimise the makespan. In this paper, we begin by describing the Job Shop scheduling problem and the evolutionary algorithm used to solve the machine allocation problem. We then, propose additional genetic operators (random selection of chromosomes to initialise the population, measuring the initial population fitness to identify good chromosomes, cloning to improve survival probability) to enhance the existing genetic algorithm in terms of getting a shorter makespan in less computational time. Finally, we investigate the effect of population size, crossover rate and mutation rate on the makespan for both the existing genetic algorithm and the enhanced genetic algorithm. Our result shows that the enhanced genetic algorithm produce the optimal makespan in a shorter genetic evolution than existing genetic algorithm.

Activity at the port with such a high mobilization, automatically spreading disease is more rapid and diverse. Seaport working area CTF class II Banjarmasin, South Kalimantan is the working area House Index (HI) is the highest in the buffer area of more than 1%. HI in the buffer area> 1% would be a potential for breeding of Aedesaegypti mosquito which can result in the transmission of Dengue Hemorrhagic Fever (DHF). Data in 2013 in the region of Seaports Banjarmasin number of cases of Dengue Fever (DD) there are 22 people and there are 2 people DHF. This research is descriptive sampling technique used was purposive sampling technique, the sample size of 66 people. The data obtained for the primary and secondary, to identify and analyze resources (labor, cost, means, methods) and the activities of planning, implementation, supervision and evaluation, and the results of vector control activities in communities and the conduct of the larvae of Aedesaegypti in the perimeter area and buffer area. Measurements conducted document analysis, questionnaire,interview and observation. The results showed the lack of power and the number of functional training in the vector Aedesaegypti control program, not maximal implementation of vector control programs namely Aedesaegypti mosquito larvae eradication (PSN) only through surveys larvae, while surveys of eggs and adult mosquito surveys are not conducted. Implementation of counseling conducted from house to house, without involving the relevant stakeholders such as community leaders, RT, health center and the port and the low implementation of vector Aedesaegypti control program in the community in the Work Area Seaports Banjarmasin is seen with HI> 1% in buffer area, and attitudes towards the implementation of the program by the Aedesaegypti vector control officers are still not maximized..
