Steam Electrics Power Sijantang Sawahlunto in West Sumatra, produce fly ash waste from coal burning which is very much every day (about 300 tons/day). Air pollution caused by fly-ash has been disturbing the community surrounding due to environmental pollution, the pollution has been carried away by water flown to the rice fields, causing the rice crops of community are damage. It is already a big problem, because the public has repeatedly protested to the PLN, even the local government had been repeatedly requested to the PLN, to resolved that the issue soon. To solved that problem, PLN in cooperation with Padang State of Polytechnic, has done some research in order to utilize the waste fly ash into building materials. The results of this study prove that the waste fly ash can be used as the basic material to produce instant tiling mortar. Through research conducted, it is found a smart way out, where "there is a problem that can be used as an opportunity" especially if people are trained and given the opportunity to produce mortar instant in their homes (home industry), it will be able to improve the economy and welfare of the people around the plant Sijantang.

The growth of cattle majorly affected by the type of fodder and its digestion system. To gain the healthy growth, cattle fed green grass and additional concentrate in form of mixed agricultural wastes such as rice straw, corn straw, etc and tofu residues in cattle fodder. Since cattle have no upper incisor, (insisivus), it use combination of its molar and its tongue to cut the grass or rice straw or corn straw, as the result more fodder like fresh grass, rice straws or corn scraws are wasted. If the wasted re-use by giving it back to cattle, it will not eat it, so it will cause inefficiency in feeding livestock. In order to solve that problem a chopping and mixing tool is needed, by using fuzzy method to control a dc motor constant speed to chopping grass, rice straws and corn straws, and then mixing with additional concentrate such as tofu wasted. Rice straws, corn straws and fresh grass are chopped in chopping section and mixed with tofu residues in the mixing section. When all the food material mixed and stired, the weight will be measures using a current sensor ACS712-20A. This sensor is used to measure the motor load. Furtheremore, if the more food materials place into this device, so, the faster the dc motor will rotate. When this device loaded 3000gr, the current measure is 4.53 ampere. The load position is not smooth will result the reading of the sensor always fluctuated. As the result, the fuzzy method applied will be optimal when the current is 4.22 ampere and the PWM fuzzy is higher than 252-mark is legible

In this paper, it will be studied existence and uniqueness solution of equilibrium points for a SEIR model with infectious force in latent, infected and immune period. From the model it will be found investigated the existence and uniqueness solution of points its equilibrium. Existence solution of points equilibrium proved by show its differential equations system of equilibrium continue, and uniqueness solution of points equilibrium proved by show its differential equation system of equilibrium differentiable continue.

Sleeve (Boom) on Crawler Crane is the main equipment that serves the weight at the time of appointment (Hoisting).The problem which is founded is a fracture at the boom while lift 6 Tons of weight while the optimum design of equipment is 50 tons. The aim of this research is to found the root cause of the fracture by using photo documentation fractografi (microfractografi and macrofractografi), and hardness tests, and test the chemical composition at the surface faults boom crane. We used Finite element method (FEM) to form simulated load. The results is that the porblem accured because of error while read the load chart and error in SOP

The sliding door is a type of door that works by sliding the door to the right or to the left. The sliding door is a type of door that is suitable for use in a room with small volume, because the sliding door does not require a large space. lack the sliding door when the door has been closed, lack the sliding door when the door has been closed, there still exists a gap between the open doors and walls so that air can be in and out freely. with the construction of the door using the hinge mechanism, can minimize these conditions. To make the sliding door works automatically, the authors make a set of control system that uses an analog system and the concept of open-loop control system. “dc motor” is used as drive for the door and “central lock actuator” as locking doors. On the control circuit voltage source used is equal to 12V. Control circuit components used are double circuit push button (NO and NC), 12V relay 8 feet, limits switches, motor DC of power windows, central lock actuator. The components were assembled for the purpose of changing the polarity of the DC motor is regulated by a relay mechanism. By changing the polarity of the dc motor, the motor can rotate to the left and to the right, so the door is connected to the motor would be moves to open and close according to the motor movement.

Preblended asbuton is one of a kind bitumen modification that used in Indonesia. From the results of laboratory tests and field trials scale, obtained that paved using asphalt mixture has better technical properties than conventional asphalt mix made bu asphalt Pen 60. Therefore, in the General Specifications of Highways 2011, this type of asphalt used for dense and heavy trafficed road. Although the long-term performance of asphaltic mixtures using preblended asbuton have not been surely known, but until now there has been a lot of road sections in Indonesia have used it. The purpose of this study was to evaluate the long-term field performance of preblended asbuton asphaltic mixtures. To achieve these objectives, filed conditions survey, testing and sampling tests have conducted on several roads that use different preblended asbuton (further named Code-O and Code-B), which has served the traffic from one to three years. In this study, the filed long-term performance of the preblended asbuton asphaltic layer viewed from the level of damage and aging asphalt development that occurs in the field. Some conclution derived from this study were that preblended asbuton Code-O or Code-B has a good rutting resistance but preblended asbuton Code-B has a better cracking resistance than Code-O. In terms of short-term aging point of view, preblended asbuton Code-O are better than asphalt Pen 60 and contrary to the Code-B, but for long-term the aging resistance either of preblended asbuton Code-O or Code-B was relative similar to asphalt Pen 60.

Sedimentation at estuary river have potency to cause floods because the narrowing of estuary as outlet. Sedimentation process can be caused by the so small river discharge at dry season so that cannot to flushing the sediment that happened at estuary mouth. When the rains arrive, river discharge which starting to big shall no long castaway to sea freely, so that causes floods in headwaters. Numerical simulation by using finite different method with Preissmann implicit scheme conducted to see ability of river discharge in early the rains to flushing the sediment in estuary mouth. Simulation was done at river with sediment elevation at + 4.00 m in estuary mouth. Boundary condition in the form of discharge hydrograph in early the rains at upstream boundary and also critical water surface elevation in sediment top and sea level at downstream boundary applied at model to see behavior of sediment transport and change of profile at bottom channel that happened. Simulation result show with 24 hours floods charge in early the rains, sediment volume of flushed equal to 20,52 %, with elevation reside at + 3,179 m. Sediment will fully under sea-water face after 9 days simulation. Change of upriver discharge and tidal elevation at downstream will influence to speed of stream that happened. By the end of simulation, the bottom profile of channel influenced of tide.
