Abstract

Natural resources, namely water, are abundant in Indonesia, which calls for all living things as a source of life. Therefore, abundant water resources must be protected and sustainably maintained, the use of water that is used properly and wisely by always taking into account the needs of children and grandchildren. The available water must be maintained in quantity and quality. Problems that often occur related to the availability of water, among others, the quantity of good water to use is limited while the need for water continues to increase, both for household, agricultural, and company needs. 2003). The decline in water quality is not only from industrial waste but also from household waste in the form of solid and liquid (Lallanilla, 2013). The purpose of this paper is to analyze the quality of river water and determine the status of the water quality of the Ayai River, Meyah District, Tambrauw Regency. The water quality of the Ayai River is based on the test results of several parameters. There is pollution downstream caused by the very high runoff, so it is contaminated with organic matter. The results of testing the water quality standards found that several parameters downstream of the Ayai River were lightly polluted. It was concluded that based on the calculation results of the Ayai river downstream of the river, there was pollution for parameters BOD5 6.4 mg/L, total phosphate 0.60 mg/L, zinc (Zn) < 0.065mg/L and Free Chlorine (CI2) < 0.12mg/ L which indicates that the water is in a polluted condition with these parameters.

Abstract

Burger Rainbow is one of the culinary businesses that market burgers with the appearance of bread that innovates colorful with varied and healthy bread fillings. Rainbow burger sales cover the Langsa City area and have a 4x4 m² area with one worker and six hours of work time/per day. Rainbow Burger sold up to 21 pcs/day. The problem with the Rainbow burger business is that the business feasibility has not been carried out while the owner of UD. Burger Rainbow wants to expand its business by adding three outlets. The purpose of the study was to analyze the feasibility of developing the Rainbow burger business regarding technology and financial aspects. The method used is NPV Net Present Value (NPV), Payback Period (PP), Internal Rate Of Return (IRR), Profitability Ratio (PR), and Break Even-Point (BEP). The results and discussion of the technical aspects of technology are all categorized as feasible, and the financial part is obtained by the Present Net Value (NPV), amounting to Rp. 21.435.626 with Payback Period (PP) investment costs that will return the capital in 1 year three days. The Internal Rate Of Return (IRR) value is 60.51%, the Profitability Ratio (PR) is 4.07, and BEP (Break Even-Point) at the time of sale to 248 units. The Rainbow burger business concludes that it is worth developing by adding three outlets.

Abstract

At this time, the discovery in the field of composites continues to grow. Using foamed polymer composites reinforced with natural fibers continues to be researched and developed to obtain alternative materials to replace metals. Composite materials have unique characteristics and are lighter in weight. Natural fibers from bagasse fiber can function as reinforcement in polymer composites. This study aimed to obtain the effect of variations in bagasse fiber on composite polymer foam materials due to compressive strength loads. This polymer composite material was made by varying bagasse fiber with a mesh fiber size of 300, 400, and 500. Three variations of the constituent materials were measured based on the density ratio of the materials. The constituent materials consist of resin, polyurethane, and fiber, respectively are: label A = (85%, 15%, 0%); label B = (84%, 15%, 1%); Label C = (83%,15%, 2%); and label D = (82%, 15%, 3%). Specimens, for each composition, are three specimens. The technique for making specimens uses the method of pouring into molds concerning ASTM D-638. The testing machine for compressive strength of this polymer composite material using the Tensilon RTF-1350 tool. From the data obtained from the results of the maximum compressive strength test occurs in the fiber size of the specimen labeled D (500 Mesh) with a compressive stress of 5.674 MPa and a strain of 0.186 mm/mm. From these data, it can be concluded that the smaller the size of the bagasse fiber, the better the tensile strength of the polymer foam composite material.

Abstract

Line balance problems are common in both the assembly and manufacturing industries. This is evidenced by the fact that some workstations have relatively high work congestion, less than Suboptimal line efficiency and non-smooth process flow this research is to: determine the line balancing by making the best path matrix based on the division of workstations. This study uses the Helgeson-Birnie method. This research resulted in design results of line efficiency of 89.16%, idle time of 2683.64, transient delay of 10.84%, smoothness index of 843.88, and 15 workstations. Based on special calculations for changes in the smoothness value, there is a decrease in the smoothness index value from 2041.72 to 843.88.
