Abstract

Proses ironing merupakan salah satu proses metal forming. Aplikasi dari proses ini diantaranya pada proses pembuatan selongsong peluru, dimana ketinggian dari dinding tergantung pada reduksi ketebalan yang digunakan. Pada penelitian ini dilakukan simulasi untuk mengetahui berapakan ketinggian dinding berdasarkan variasi reduksi ketebalan dinding sehingga didapatkan ketinggian yang sesuai dengan kebutuhan dalam pembuatan selonsong peluru. Material yang digunakan untuk selongsong peluru kaliber 20 mm adalah kuningan Cu30% Zn 70% berbentuk cup diameter luar awal 33,5 mm, tebal 3 mm dan tinggi 37 mm. Berdasarkan perhitungan kekuatan material, maka didapat reduksi ketebalan dinding maksimum yang diijinkan pada proses ironing adalah 26,7%. Selanjutnya dengan reduksi tersebut dilakukan simulasi menggunakan metode elemen hingga pada variasi sudut die α = 5ᵒ, 10ᵒ, 15ᵒ, 20ᵒ dan 25ᵒ. Hasil simulasi proses ironing pada masing-masing sudut die α dan prosentase reduksi ketebalan dinding 26,7%, menunjukkan, bahwa selongsong peluru belum dapat melawati die. Setelah dilakukan penambahan gaya pada proses simulasi dan dengan variasi reduksi 5%,10%,15%, 20% dan 25%, menghasilkan untuk reduksi 5% :39mm ,10% : 42mm ,15% : 45mm, 20% :51mm dan 25% : 55mm.

Abstract

Honey is a natural sweet substance produced by bees with nectar flower ingredients containing various nutrients such as carbohydrates, proteins, amino acids, vitamins, minerals, plant pigments and aromatic components. Honey consists of water (17%), fructose (38.2%), glucose (31.3%), other disaccharides (5%), melezitose (<0.1%), erlose (0.8%) , other oligasakarida (3.6%), minerals (0.2%), amino acids (0.3%). It also contains anti-microbial substances, which can prevent some disease on human. Because it has a high economic value and contains unique substances, honey is often falsified. Honey can be faked in various ways by mixing natural artificial sweetener components or by giving the sugar (sucrose) into the honey, so it is dangerous if given to infants or people suffering from diabetes mellitus. The design of this research used spectrofotometer methode and pattern recognition algorithm (machine learning) system for classifying honey quality. It is based on honey having a chromophore group responsible for absorbance, electronic transition and color giver. We can also knowing the type of honey by using pattern recognition algorithm support vector machine.In this research is used three types of honey to using a spectrophotometer at a wavelength of 500 nm, the absorbance obtained in randu honey type of 0.523-0.654, coffee honey for 0.735-0.824, and rubber honey by 0.947-1.043.

Abstract

The many types of production of goods in a company spearhead the progress of this company in industrial competition in Indonesia, the variety of types of products and large production capacity makes this company need a large number of employees to balance the variety and production capacity. This large number of employees creates its own problems, one of the problems is employee performance appraisal, employee performance appraisal in this company is only centered on the highest supervisor's consideration in one section. From that problem, the researcher wants to solve the problem using the Balanced Score Card (BSC) method by using the determination and weighting of Key Performance Indicators (KPI). The final result of the research conducted at PT Alam Jaya Primanusa in May 2018 the results of the following employee achievement grades and categories: Average material value: 76.65 Fair category, Operator's average value: 85.51 Good category, Average value - Selector section average: 89.79 Good category, Packer section average value: 94.98 Good category, Values ​​in each of these sections become the basis for calculations for all injection division production, so conclusions are drawn for the final value and achievement category of all injection division production the value of 83.37 in the Fair category.

Abstract

Many processes in the industry originally done by humans, are now being replaced by machines that are driven automatically by simply giving commands / programs or just simple / semi-automatic buttons. This is intended for human energy efficiency and the effectiveness of completion time, due to the rapid progress of human resources (Human Resources) so that it is no longer possible to do the work manually with great energy.This Final Project aims to plan, manufacture, and test semi-automatic press machines for the purpose of automation of engine press. Methods in the design of this machine is the study of observation. From the design is done, generated a semi-automatic press machine, with the following specifications: Capacity of compressive strength with the power of pressing 150 kg. The electric motor used has a power of 0.5 PK and 1400 rpm rotation. Total cost for the manufacture of 1 unit of this machine is Rp 1.714.000, -.

Abstract

In line with the times, the need for product development ideas has a high selling value. Economic value and product efficiency are highly considered in the design, one of which is the design of a stall or café chair. In general, the most used seats are permanent. In other words, it can't adjust when used for a few people or for a lot of people. Therefore it is necessary to design stalls and café chairs that can be stretched or shortened automatically. The purpose of designing this elongated chair is, it can be arranged so that it can be shortened, with this advantage we can save space and expand the space and of course it will be designed according to consumer needs. The elongated chair is made using the Quality Function Deployment (QFD) method. Some methods that must be done, namely the Voice of Customer collection phase, which is done by distributing questionnaires to 25 respondents. The next step is House of Quality based on the results of the questionnaire. After the HOQ is completed, then the analysis and implementation phase of the results obtained at HOQ will be applied to the product design.

Abstract

there is a previous study analyzing the design of ergonomic chairs for pond machine operators, where the analysis uses the RULA method manually, Based on the results of data processing with the RULA method, it can be concluded that the posture of the ring making operator (washer) operator with a slightly bent body position has a score value 5, and the chair design based on the redesign of the pond engine operator chair shows that the final result is 3. (Mukhtar, 2018) In this study, a productivity analysis is carried out to measure the level of chair productivity by considering several aspects of work activities, The method used is the Objective Matrix (OMAX) and the determination of the score from the performance appraisal using the Analytical Hierarchy Process (AHP) method. The results obtained are Productivity increased from before, because it is still in the range of 3-10 (based on the matrix table the score 3-5 is good enough, 6-8 good and 9-10 very good) and the lowest values ​​shown in this table are 3 and 4 Based on the scores, the scores are still quite good. But there still must be improvement. Overall the level of productivity has increased compared to before. But there are still fluctuating data. This is due to the lack of uniformity in the ability of the opeator to run the pond engine in washer production.
