We consider a public transport with government subsidy to encourage the sustainability of the transportation. The transportations revenue is determined by the maximum of the uptimes of the vehicle.
In this paper, we study a one dimensional maintenance policy for new vehicle which is characterized by age parameter. We consider that the degradation of the vehicle is affected by the age of the vehicle, and modelled by using a one dimensional approach. The owner performs both preventive and corrective maintenance actions, and the preventive maintenance action will reduce the vehicle failure rate and hence it will decrease the corrective maintenance cost during the life time of the vehicle.
The decision problem for the owner is to find the optimal preventive maintenance time of the vehicle of each subsidy option offeredby maximizing the expected profit for each subsidy. Topic Engineering and Technology Innovation. Job and Workload Analysis System for Civil Servants in North Sulawesi Province Made Krisnanda aAlfrina Mewengkang bParabelem Rompas b. a,b Faculty of Engineering, Manado State University, Indonesia. The realization of good, clean and dignified governance are important, yet hard to accomplished.
Reform of the bureaucracy is one solution that can realize increased efficiency, effectiveness, transparency, and accountability of government. However, bureaucratic reformation program in Indonesia faces many obstacles. These symptoms could be seen from the arrangement of the system of government that is still abstract, yet detailed and overlap.
Such conditions lead to workloads that are not measurable and clear, confusing, using random procedure and difficult to justify. The Government of North Sulawesi province is one of many provinces that have these constraints. In 2014 Capital Jakarta made a policy to rearrange civil servants management which consists of three steps. First is job analysis, workload analysis, and the last one is adjustments to remuneration or allowances performance.
This arrangement includes all parts of civil service positions, both general echelon, and functional position. Currently, the government of North Sulawesi province already has their own framework for analyzing the position and the workload of employees. Job analysis step consists of eleven criteria. These criteria use as the workload assessment and calculation of the amount of allowances and remuneration of employees. Maintenance Policy in Public-Transport involving Government Subsidy Udjianna S.
Unfortunately, the Implementation of position analysis and workload of civil servants still manage manually based on paper. Many times the reports of many working units in North Sulawesi province could not finish at the end of the year. For example, even has been working through 2015, only 90 of civil servants performance reported to the capital. This effect monitoring and evaluation of civil servants works.
This study is intended to assist the provincial government in conducting job analysis and analysis of the workload of civil servants with a new computer-based system. Currently, the implementation of the analysis is done manually by paper and done by the whole agency and the existing provincial environmental agencies. In the initial phase, researchers will create a system that is compact and can be installed in each office. This system will facilitate provincial and central governments in determining the performance benefits of employees based on the results of job analysis and workload.
It is expected to shorten the time of filing form and analysis of the results of the charging data. Utilization of Beeswax Phase Change Material to Improve Solar Panel s Performance Razali Thaib aT.

It reduces crop failure compared to traditional farming and increases production of crops using automation.
In the proposed system, iqoption api documentation cart-rail robot is used to automate different farming tasks. Unlike a conventional system that usually uses rack and pinion or is limited to 1 Degree Of Freedom DOF motion, the proposed system uses a cable that actuates the entire motion of the cart providing 2 DOF motion. A cart attached with four spherical wheels slides on a dual shaped U rail track and is pulled using a haul cable.
As it works like a Cartesian robot, the motion of the cart is constrained to the XY plane and further constrained to the rail. The rails are laid out in columns with a single row. Vertical shelves stacked with crops are kept beside the column rails. The motion of the cart through each axis is controlled by a capstan transmission drive. The position of the cart is sensed by quadrature encoder coupled to the motor.
Physical modelling is done to represent the dynamics of the cart. A closed loop linear feedback controller was designed using state-space representation and the gains were selected using pole placement method. 1cm accuracy in braking distance was achieved, for the cart-rail robot to transit from the row rail onto the column rail.
Velocity is limited to the range of 0. 2m s for the given payload of 20kg. It was observed that a steady state in breaking distance is achieved with an overshoot of 0. This paper also discusses preliminary trials conducted by mounting a pesticide sprayer mechanism on the cart to validate the tracking effectiveness of the designed controller. A study of the variation in braking distance due to change in payload was done.

Tunelling current calculation on Si Si1-xGex Si heterojunction bipolar transistor is done by including the coupling between transversal and longitudinal components of electron motion. This analytical tunneling current model is then used to study how the germanium concentration in base to Si Si1-xGex Si heterojunction bipolar transistor influence the tunneling current.
It is obtained that tunneling current will increase as the germanium concentration given in base decrease. The calculation result shows that the coupling between kinetic energy in parallel and perpendicular to Si1-xGex barrier surface affect tunneling current significantly when electron velocity is faster than 1x105 m s.

Currently Manado is developing sustainable coastal tourism development policy. Sustainable tourism must be able to adapt to the condition of society without ignoring the environment. The extent to which the process of development of sustainable development is determined by the role of community participation involved in the development of tourism. This study attempts to identify the level of community participation involved in tourism development in the coastal area of Manado Bay to be a model of sustainable regional development.
The findings of the community participation level will be translated into a development model as a new mechanism in a sustainable development approach. The level of community participation in tourism development in Manado City is measured in the form of quantitative research in the form of questionnaires to community based on the level of community participation developed by Sheery Arnstein with purposive sampling technique.
The level of participation developed by Sheery Arnstein successively from the low level of high Manipulation, Therapy, Informing, Consultation, Placation, Partnership, Delegaten Power, Citizen Control. The results revealed that the level of community participation in tourism development in the Malalayang coast of Manado Bay was at the consultation level. The level of consultation shows that the government invites public opinion after being informed to the public and there has been a two-way dialogue between the government and the community.
The community has provided input and active discussion through the two way dialogue. Although there has been a two-way dialogue, but this way the success rate is low because there is no guarantee that community concerns and ideas will be noticed. The findings of the level of participation were then developed into a model of sustainable tourism area development mechanism.
