Abstract

ABSTRACT Eggs are one of the foods derived from poultry and is a popular source of animal protein food and is very popular with the public. Many of the people who open businesses as chicken egg breeders. The business will be marketed to consumers by sorting beforehand, both from the weight equality and sorting between eggs both rotten and rotten. However, in doing this sorting, chicken egg entrepreneurs still do it the conventional way, namely by using hand palms and lighting lamps. So it is very ineffective and inefficient. Therefore, in this study an egg grading machine was designed, which is a machine that is able to work for egg sorting based on the good and bad conditions of eggs and based on egg weight. This machine works automatically, by utilizing a microcontroller accompanied by the use of weight sensors and light sensors. Weight sensor here which works as an egg sorter based on the type of weight. While the light sensor works in the process of selecting good and bad eggs. This machine was made due to lack of egg grading machine production. It is known that the market of the egg grading machine is still on the market of China and Europe with prices that are still high. So by making this machine it is expected to be able to meet the needs of the Indonesian market at a relatively cheap price. Keywords: Egg Grading, Microcontroller, Weight Sensor, Light Sensor

Abstract

The classification of landscapes has been put forward by many experts in geomorphology. One classification commonly used is the Van Zuidam classification. With various interpretations of the reader, the use of this classification is often debated. This paper wants to mediate the differences of opinion or diversity of interpretations by modifying the landscape classification of Van Zuidam (1983) and Van Zuidam - Cancelado (1979). Several constraints which constitute the shortcomings and advantages of classification were raised to clarify this critique process. The process of unifying the landscape is also expected to be more easily understood and adjust the standard Indonesian language rules. The procedure for determinating landscape units can be done with various parameters but it should be done with procedures that mainly consider the contour pattern and genetic similarity of the landscape. This paper proposes the existence of 17 sub-classes as details of 7 main morphometric classes made by Van Zuidam & van Zuidam-Cancelado (1979).

Abstract

Separation of defective products in the industry is needed so that the quality of circulating products in the market is guaranteed quality. An error in the production of bottled drinks that may occur is the presence of bottled water that has not been filled. Separation of defective products that have been done manually by workers allows errors to occur due to fatigue. To prevent this in this study, designing and making an automated tool for separating defective products in beverage packaging using the Programable Logic Controller (PLC). Bottles that have not been filled with drinking water running on the conveyor will be detected by the proximity sensor capacitive. Packaging data from the capacitive proximity sensor is shifted in memory by the Shift program instructions, each photoelectric sensor detects the presence of packaging that runs on a conveyor. At a certain position, data from packages that have not been filled with drinking water are used as an electric solenoid valve pneumatic command activating the cylinder / piston to separate the defective product from the disposal site.Keyword : product selection, PLC, sensor

Abstract

ABSTRACT Calvary Abadi Klaten is an andesite processing plant located in Somopuro, Jogonalan, Klaten, Central Java. The average monthly total production is 51.000 m3. There are four products: 5mm-10mm split stone, 10mm-20mm split stone, 20mm-30mm split stone, and stone ash. The criteria used in this study are NPV (Net Present Value), IRR (Internal Rate of Return), and PBP (payback period). A project is feasible if it fullfills three conditions: NPV is bigger than zero, IRR is bigger than minimum interest rate specified (i *), and PBP is shorter than project life. Sensitivity analysis is used to determine the sensitivity of the project if some of its main variables changed. This study used two capital structures. The first capital structure was 60% own capital and 40% loan capital, and the second was 100% own capital. Based on the calculation results, the first capital structure obtained NPV = Rp. 12,857,234,525, IRR = 42.8%, and PBP = 2.97 years. And the second capital structure obtained NPV = Rp. 9,897,703,535, IRR = 30.1%, and PBP = 3.83 years. Based on the results above, can be concluded that andesite stone processing project at PT. Calvary Abadi Klaten is a feasible project. Based on sensitivity analysis, the project was still feasible when operating cost increased up to 10% and revenue (selling price) decreased up to 10%.
