Abstract

Micro, small and medium enterprises have an important role in supporting the national economy. They need to be supported to be able to compete globally. This study aims to design a banana chip slicer machine by considering the ergonomics of the research partners. The object of the research is the process of banana slicing done by a banana chips maker located in Kediri Regency, East Java Province. The Business actors have been running their business since 2010 with 10 employees. Slicing is one of the key processes which determines the product quality in the manufacturing of banana chips. The problem that occurs in the object of observation is that the chopping is done manually, carried out with the same movements, and repeatedly, takes a long time to cause musculoskeletal disorders, namely impaired function of the muscles, joints, and spine. The problem that occurs in the object of observation is that the slicing was done manually for a long time, carried out with the same repeated movements, causing cause musculoskeletal disorders, namely impaired function of the muscles, joints, and spine. In addition, workers must be trained and precise in slicing bananas to get the same thickness. Slicing is done on a wood-fueled pawon stove which interferes with breathing. Furthermore, the slicing movements must be carried out as quickly as possible which can result in injury to the hands and their muscles. In the current condition, the research results showed a high RULA value, namely 6. Optimization was successfully carried out with two schemes. The first scheme used a slicing machine design using arm support and repetitive motion. While the second scheme used a slicing machine design with arm support and intermittent movement. The simulation of the two schemes showed a decrease in RULA value from 6 to 2, which means the process is acceptable and safe for workers.

Abstract

The phenomenon of flooding that occurs in various parts of the world continues to increase, both in terms of frequency and amplitude. Without neglecting the morphology of the region, global climate change and changes in land use as a result of economic growth are the main factors causing this disaster. Understanding flood characteristics, be it discharge, inundation height, and their distribution in an area is very important as a basis for determining flood control efforts. This study aims to analyze the level of flood vulnerability based on the characteristics of the occurred floods. Hydrological and topographical analyzes were performed as the basis for the flow hydraulics calculations performed with Hec-RAS 2D version 5.0.7. The flood distribution simulation results with return periods of 2, 5, 10, and 25 years show that the area of ​​the village that has the potential to be inundated is ± 22.57 ha, ± 37.11 ha, ± 41.81 ha, and ± 47.27 ha, with inundation heights varying between 0.25 m. – 1.50 m, which can be classified as low to high hazard.

Abstract

One of the facility units that acts as a supporter of student learning in a university is the library. The library is a place where there are various collections of libraries that can enrich the knowledge of visitors. Thus, the management of additional collections is important in supporting this. Currently, the addition of book collections in the UNG Engineering Faculty Library is only based on references from statistical data on best-selling books, lecturer recommendations and the latest books without considering which collections are of interest to students. This can have a negative impact if there are additional collections in categories or types of books that are less desirable to read which can cause problems from the service side and financial losses of the library. Moving on from this problem, the K-Means clustering method will be applied to classify the reading interest of library visitors in this case are students. The supporting variables that will be used in the grouping will be divided according to the origin of the student majors by category of books, stock, number of books borrowed and number of books read. This grouping is expected to be a recommendation for library managers in managing the addition of book collections in the UNG Faculty of Engineering library.

Abstract

The increase number of vehicles is not the main factor causing congestion. There are other factors, such as the movement of pedestrians crossing the road using a zebra cross. This study aims to determine the effect of pedestrians crossing on vehicle queue lengths using shock wave analysis, and evaluate whether zebra cross facilities are still suitable for use or not at research site. This research was conducted for 4 days on Sam Ratulangi street in front of Multimart Ranotana Manado City. Data analysis uses traffic characteristics correlation of volume, speed and density. The characteristic correlation that will be used for the shock wave analysis calculation is based on the highest coefficient of determination (R2). The results of the study, based on shock wave analysis showed that pedestrians crossing could make a vehicle queue length of 33.5 meters for the left lane and 74.6 meters for the right lane. Based on the average number of pedestrians crossing the volume of vehicles and the number of conflicts that occur (PV2), it is recommended that the type of crossing facility is pelican with a protector. The greater duration of pedestrians crossing (r) then the maximum queue length of vehicles (Qm) will be greater.
