2023-02-16T14:10:10+08:00

The design of a good and safe piping system is needed to ensure the continuity of the production process and
ensure safety. To overcome the magnitude of the stress that occurs due to loading, analysis is needed. In this
final project, the stress of the High Pressure Vent Pipeline will be analyzed with the CAESAR II approach
and with the Allowable Stress limit of ASME B31.3. In this final project, a discussion of the piping path from
the Pig Launcher outlet to the Pig Receiver inlet is carried out with line number ”-PG-KT-A02A-016, 8”-
PG-KT-A02A-027, 2”-02-BV-024 dan 2”-02-GLB-004. The design starts from collecting data, analyzing the
pipe thickness (pipe schedule) from the type of material used in the initial design which refers to the ASME
B31.3 Process Piping standard. In the redesign, the support distance is below the maximum span limit,
which is less than 8m so that it does not provide deflection and excessive stress on the piping system.

The success of the national health insurance program (JKN) requires certainty of the availability of drug
supplies and medical devices from local industries. The limitation of the local medical device industry is an
obstacle to the success of the program, and then released national program to accelerate the development of
the independence of the national medical device industry. This research is intended to find an alternative
way to accelerate the development of the medical device industry by developing upstream technology,
namely product design and development. With this technology, an effective way of developing medical device
products for small industries will be obtained, the product reaches the market immediately, and meets
regulatory requirements. The product used in this case is a baby cot. The product development model used is
to follow the regulatory requirements for good medical devices manufacturing practices (CPAKB), SNI ISO
13485 and a systematic approach to design a product that is safe, and effective as intended use. Information
on product requirements and test methods is taken from EN 1130 Part 1 and Part 2. Using a systematic
approach the requirements and functions for the product can be analyzed. Furthermore, the embodiment
design and detailed design are developed. The correctness of the design is proven by making functional
prototypes and verified by the stipulated design requirements. From this research, it was found a way to
develop medical device products for baby box products that are safe, and effective as intended use meet
regulatory requirements.

ANALISIS KUALITAS BATANG PISTON ORIGINAL DAN NON ORIGINAL PADA KENDARAAN RODA DUA 4 LANGKAH KAPASITAS 113 CC

Quality Analysis of Original and Non-Original Piston Rods on Two-Wheel Vehicles 4 Stroke Capacity 113
cc, piston rods are important spare parts on motorcycles, because their function is to transmit the power
generated in the combustion process from the piston to the crankshaft on the vehicle. If there is damage to
the piston rod which can cause the piston rod to be bent or even broken, so that it has an impact on the
safety factor when driving a motor vehicle. The purpose of this study was to determine the mechanical
characteristics of the piston rod material (connecting rod) of original and non-original products, and to
compare the quality of the piston rods of original and non-original products from two different
manufacturers. The method used in this study was the ASTM E 3 microstructure test, the SNI 19-0409-1989
hardness test, and the ASTM A 751 chemical composition. Metallographic testing revealed that the
microstructure of the original motorcycle piston rod was tempered martensite with a fine grain of 60-80 cm.
70%, while the microstructure of the non-original motorcycle piston rod is tempered martensite with 40%
coarse grain. Medium hardness test The hardness value of the original piston rod material is 428 HV, which
is higher than the non-original motorcycle piston rod material hardness value of 396 HV. As well as testing
the chemical composition that the value of the element Al contained in the original motorcycle piston rod
material is 0.0314% > 0.0184% non-original motorcycle piston rod material in the chemical composition
testing process.

ANALISIS PENGARUH FEEDING PADA PROSES GRINDING JOURNAL TERHADAP NILAI KUALITAS CAMSHAFT TYPE 2TNV70 PASCA IQT

2023-02-16T14:34:45+08:00

Research in the field of machining in testing the level of roughness needs to be done to get good results in the
machining process. The purpose of this study was to determine the effect of variations in feeding on the
surface grinding process on the surface roughness and hardness of S45C carbon steel that has gone through
processes including induction, quenching and tempering and to compare which feeding variation has the
lowest level of roughness. The research method used is an experimental method in the form of giving a
variety of feeding which is tested on 4 samples in the surface grinding process. The number of variations
given is 0.2mm/min, 0.4mm/min, 0.8mm/min, 1.2mm/min. The test results obtained are in the form of
roughness values and hardness values on specimens that have been previously tested. The results showed
that there was a change in the roughness value that occurred during the grinding process by applying a
0.2mm/min feeding variation resulting in an average value of 1.33683333µ, a feeding variation of
0.4mm/min producing an average value of 1.27068333µ, a feeding variation of 0.8mm/min producing an
average value of 1.27068333µ. the average value is 1.29633333µ, the variation of feeding 1.2mm/min
produces an average value of 1.39458333µ and there is no significant change in the surface hardness value
in the surface grinding process. The tools used in this study were the Mitutoyo SV2100 rougness tester to
determine the roughness value, and the Sonohard SH22 hardness tester to determine the hardness value. The
data that has been obtained are then analyzed using descriptive statistics where the data are presented in the
form of tables and graphs. after grinding. This shows that there is an effect of giving different variations of
feeding the surface grinding process to the surface roughness value.

ANALISIS KEGAGALAN GEOMETRI KOMPONEN BRACKET HINGE CAB PADA PROSES BORING DIMESIN CNC MILLING OKK VC51

The Boring Process of Hinge Cab Bracket components is one of the machining processes at PT. MMI.
Boring work is the process of enlarging the hole to the desired size and usually pays less attention to
geometric deviations from the results of the boring process, even though it greatly affects the quality of the
machining results. In general, a spherical profile is said to be perfectly round if the distance of the points
contained in the geometric shape have the same distance from a point called the center point. The purpose of
the study was to determine the effect of spindle speed and feeding speed on the geometric size of the barcket
component. The method used in this research is an engineering study with experiments and data collection is
carried out through field observations and analysis of ongoing programs. The independent variable in this
study was 0.1 mm infeed depth, with spindle rotation parameters of 400 rpm, 500 rpm, 600 rpm, 700 rpm
and 800 rpm. The dependent variable is the geometric deviation of the Bracket Hinge Cab boring results.
The control variable is the insert type TNMG332-GN LC5010 which has a feed speed (fz) of 0.1 mm/rev and
a roughing size of 104 ±0.30, coolant damin water and ecocool 2700T. The measurement method uses a bore
gauge/cylinder gauge to determine the effect of variations in machining parameters on the geometry of the
boring results with a tolerance of ± 0.30 mm and takes 4 axes of measurement, namely X, Y, X', Y'. From the
research that has been done that the parameter with the smallest geometric deviation is obtained in the four
parts with a spindle rotation (n) 700 rpm, which is the expected result because the geometric deviation is
70μm, still within the tolerance limit of ± 0.30 mm and has a roughness level of 9.278 Ra. The greater the
value of the cutting speed (Vc), the smaller the geometric deviation that occurs. To get good results based on
the analysis and for results that are in accordance with the standard, the best Rpm is used at 700 rpm with
Feeding 140 mm/minute.
