Abstract

Designing on the Waste Water Treatment Plant, often overlooked by variations in water pressure at the time of empty water reservoirs suddenly, so the designing often assumes that the water load is a static load.The case reviewed on the WWTP wall structure is evident that water also has unique behavior especially in large structures. Careful planning certainly will not lead to anything like the case occurring in this research review.The repair or reinforcement analyzed through the Hydro Test testing behavior concludes that without dismantling the entire building, it can still revert to the planned needs of the WWTP building structure.The analysis performed using the finite element method tool to speed up the calculation states that by increasing the number of existing reinforcement can improve the ability of WWTP structure.

Abstract

Three Phase Induction Motors are widely used in the industrial world, therefore induction motors are expected to operate normally according to the desired work characteristics. But can not be denied the existence of interference that can cause damage to work induction motor system that one of them is harmonics. The purpose of writing this article is to explain the working characteristics of three phase induction motor which generates harmonics and in operation also contains harmonics. The method used in the study analyzed the working characteristics of three phase induction motor which in its operation contains harmonics. The harmonic form is analyzed by using Fourier series representation. The results obtained from this study indicate that under operating conditions containing harmonics, the stator magnetic field generates a rotating harmonic field that produces a forward and backward mmf mmf. Another effect of this harmonic, is the incidence of harmonic torque which coincides with the fundamental torque produces vibration and noise which has considerable effect on the operation of three phase induction motors.

Abstract

This research is the creation of a simple new technology by manipulating the hydraulic system and the principle of hand grip that functioned as an ergonomically adjustable twistable short cutter, with a normal length of 1.5 meters, a maximum of 3 meters. Weight 2.8 kg, long grasp of 94 mm and the diameter of the handle 52 mm. This research uses ergonomic analysis method to know suitability of tool with human that is with taking 95 percentile. At the diameter of the hand grip 54, 29 mm while for the width of the palm of the hand is 97.87 mm, the maximum pressure required to cut the twig is 234.39 kg / cm2 with a diameter of 5 mm that is the type of twig cocoa. While the NIOSH analysis obtained the required weight is 4.89 kg, then with the QEC method obtained the highest percentage level of the score is 47.62. it means repair is needed for the tool in the future. For the loading of work so as not to tired with working time of 8.40 minutes and rest 7.14 minutes. The results of the study concluded that the tool still has to be repaired in the future, while its use is quite short and only functioned for clove planting only and other similar harvesting with a maximum diameter (1 cm) only.

Abstract

It is commonplace when architectural designs that require beauty often do not pay attention to the strength of building structures as part of a unity of structures and architecture of buildings, forgetfulness of the part of the building that was originally assumed not to bear the burden in the end should bear the burden causing a new design adjustment. The study of pipe columns as poles on cantilever building structures was studied because of the concerns of the building owner and also the construction executor of the cantilever frame design. The position of the pole as a successor to the load from the roof to the foundation is noticed because the steel material is elastic and also weak against buckling. An examination of the modified section of the frame structure is absolutely necessary to increase the stiffness of the structure, so that the pipe columns with small dimensions according to the architectural design can be maintained.

Abstract

This research is motivated by the problem of production area condition in UD. Jamal bread and irregular work facilities. This is, seen in operators working in empty areas and the laying of baking pans that almost fill the work area and placed carelessly (uncluttered) at the bottom of the production floor. The purpose of this research is to design the layout and work facilities by combining BLOCPLAN so that operators work comfortably, safely, and healthy in doing their work. The proposed improvement plan is the layout design with BLOCPLAN taking into account the placement of the proposed work facility design. There are 3 (three) designed proposed facilities that are used for empty pan, baking rack used for baking sheet, as well as frying pan. the total displacement moment occurring in the layout design and the proposed facility is 1178 meters displacement / day, then there is a decrease in total displacement moment of 4088.4 meters displacement / day.

Abstract

Oil palm plantations are highly developed in Indonesia Especially North Sumatra. In the process of oil palm harvest, will produce palm kernels that fall to the ground. the oil palm seed is a mature palm fruit and can be sold. Based on preliminary observations with partners, they have difficulty in collecting fallen palm kernel. So many of the seeds of palm oil are abandoned and not sold. Farmers' income is reduced due to wasted crops. The absence of work facilities that occupy and the exhaustion of workers is the cause of farmers do not collect the seeds of palm. The activity of collecting palm kernel seeds is still done manually. The use of farming tools to collect palm kernel seeds facilitates the collecting of fallen palm kernel, so that the harvesting activities become effective and efficient. In the end it provides increased income for farmers. There was an increase in Partner's revenue of Rp.372.000, - and Partner 2 of Rp. 618,000, - in September 2017 using a palm kernel collecting apparatus.

Abstract

This research aims to know the quality of service ocean freight based on user perception. The service quality was explored is performance in Regional Port of Sanana and passenger ship KM. Intim Teratai, KM. Theodora, and KM. Bunda Maria.The instrument of service quality was adopted from 5 service quality dimention by Zeithaml, Parasuraman and Berry. Data collecting through spreading of queationnaire to service user and ship passenger in Regional Port of Sanana. The study successfully obtained 400 respondents (100 service user of port, 100 passenger of KM. Intim Teratai, 100 passenger of KM. Theodora, and 100 passenger of KM. Bunda Maria). The analysis was done by using Importance Performance Analysis (IPA) and calculating the Customer Satisfaction Index (CSI).Results were obtained with mean index value of port service user satisfaction from 8 service factor is 54,74 percent which satisfied the criteria entered. Complement facility in port terminal factor and information of ship schedule factor is entry to criteria less satisfied and get the prority for improved performance. Mean index value of ship passenger satisfaction KM Intim Teratai is 53,98 percent is entry to criteria sufficient satisfied, KM. Theodora is 55,10 percent is entry to criteria sufficient satisfied, and KM. Bunda Maria 67,10 percent which satisfied the criteria entered.
