Abstract

Indonesia has a very large area of ​​oil palm plantations, one of which is the island of Sumatra. However, in processing and handling palm oil product waste in the form of palm shells, it has not been maximized. Therefore, the chemical decomposition process can play an important role in supporting waste management and sustainable energy use in Indonesia which is not yet optimal. In this research, the proper use of power will be tested with the help of microwaves as a reactor for the co-pyrolysis process of oil palm shells and polystyrene plastic. The purpose of this study was to determine the appropriate power to produce maximum co-pyrolysis products and to investigate the physical characteristics of the oil-pyrolytic products. The test uses a microwave oven which has a power variation of 300 W, 450 W, 600 W, and 800 W with the addition of a catalyst. The ratio of the composition of oil palm shells to polystyrene plastic is 1:1 with a total mass of 105 gr and using coconut shell charcoal as an activated carbon absorber. The pyrolysis temperature is 500 ℃, the nitrogen gas flow rate is 1.5 LPM, and the pyrolysis time is 60 minutes. Furthermore, testing the physical properties of the pyrolysis oil product in the form of density, acidity, and viscosity testing. The results showed that the optimal power to obtain oil-pyrolytic was 600 W with a product oil of 17.6%, and from the physical properties it had a low viscosity value of 2.55 mPa.s with a pH level of 6.6.

Abstract

Characteristics from design boat capacity 3-4 people or 250 kg good for used access between island small in area tour with depth shallow base. The resistance of the boat's hull when operating plays an important role in knowing the power required by the boat. This is very important in designing a hull. Therefore, in design This will be done in numerical simulation using Computational Fluid Dynamics (CFD) to know how much power is required by the boat with a number of variation speeds. Design simulation moreover formerly created in Autodesk Inventor software, then design that has been designed will be simulated using the Ansys Fluent CFD application program. The data variables used in simulation numeric using varying speed limits namely 20 knots, 16 knots, 12 knots, 8 knots, and 4 knots, as well as condition rate flow is turbulent, wall side and top is symmetry, and the part the design that will be simulated is part hull the boat that sank in the water. The result of simulation numeric boat 250 kg capacity indicates a number of pressure and velocity contours of part hull as well as obtained Power highest at a speed of 20 knots 13938.511 Watts.

Abstract

Kebutuhan energi terbarukan dalam beberapa dekade terakhir semakin meningkat akibat dari keterbatasan sumber daya energi fosil dan isu lingkungan. Salah satu teknologi yang berpotensi besar dalam pemanfaatan energi terbarukan adalah kolektor panas surya. Penambahan sirip pada kolektor panas merupakan salah satu cara untuk meningkatkan unjuk kerja termal kolektor panas plat datar. Secara praktik dibutuhkan sirip pembagi aliran udara agar dapat menjangkau dan mengambil panas dari setiap sisi sirip kolektor panas. Hasil penelitian menunjukan sirip pembagi aliran dapat meningkatkan unjuk kerja termal kolektor panas plat datar bersirip. Sudut yang paling optimal dalam meningkatkan unjuk kerja termal kolektor panas plat datar bersirip pada penelitian ini adalah 30o.

Abstract

This study aims to synergize pyrolytic oil products obtained through co-pyrolysis of biomass (palm shells) and food packaging waste (polystyrene) with the addition of a mixture of natural zeolite catalysts and CaO using a microwave-assisted. The main raw materials of palm shells and polystyrene are mixed with a ratio of 1:1 plus coconut charcoal as absorber 50% of the total main raw materials, and the catalyst mixture ratio is 1:1. This study used microwaves as a reactor with various power variations, namely 300 watts, 450 watts, 600 watts, and 800 watts. Analysis of pyrolytic oil products in the form of calorific value using a bomb calorimeter and chemical composition using mass spectrometry. The results showed that the optimal power to use was 600 W, with a calorific value (HHV) of pyrolytic-oil of 40.10 MJ/Kg, and a percentage of compound content of 99.19% dominated by aromatic compounds 17.83% and aliphatic 76.93% with high hydrocarbon content.

Abstract

Biomaterials is an advanced material engineering technology that is used to help heal bone fractures or fractures. Currently, many biomaterials use materials such as titanium alloy, stainless steel, platinum, and chromium, but these materials cannot be degraded naturally so a second operation must be carried out to remove the installed biomaterial. Biomaterials are temporary in nature so when the bone returns to its original state, the biomaterial must be surgically removed. Research was conducted to obtain a design with a material that can be naturally degraded without causing toxicity. Magnesium AZ31B is a recommended candidate as a base material for degradable bone implants. Magnesium AZ31B material, it is expected to reduce or minimize the surgical removal of implant biomaterials. Bone plate geometry  use plate  bone  dimension 150mm x 15mm x 3mm with  variation 10 hole parallel and zigzag as well as with a bolt  bone  dimensions  long 40 mm with pitch 1mm diameter 5mm. Test bending was conducted  with ASTM E290-14 showing  that on plate  bone  hole parallel  with  burden  maximum 33,419 KN with a deformation  maximum of 30.89 mm whereas  for  plate  bone  hole zig zag with the burden  maximum 32,863 KN with  deformation  maximum big as 29.97 mm. From the study  experimental  that  plate  bone  hole  parallel  have  nature  mechanic  more  tall  compared  with  plate  bone  hole zig Zag although  with the difference which is not significant. Whereas on simulation FEA plate bone  hole  parallel  with  burden 33,419 KN get  results total deformation  as big as 31,481 mm with von Mises stress 15,337 MPa, then  for  plate  bone  hole zig Zag with  burden 32,863 KN with total deformation 32.466 mm and von Mises stress as big as 33,948 MPa. In testing by  experiment and simulation FEA plate  bone  hole  parallel  get  difference  around 0.591 mm or 0.94% whereas  for  plate  bone  hole zig Zag in  testing  by  experiment and simulation  get  difference  around 2,893 mm or 4.60%.

Abstract

This research aims to design and create a sms-based motor vehicle security system with an ATMega 8535 microcontroller. This research utilizes hand phone technology and microcontroller. Making this tool has an economical price to secure motorized vehicles. Important prototypes in making this tool are the ATMega 8535 microcontroller, GSM Modem and HP. In making this tool the first thing to make is to make a microcontroller program for the controller. Making this program uses CV Avr soft ware (Code Vision Avr). After the program is finished, the program is downloaded to the microcontroller. Control is done by the microcontroller when it gets input. The result of this research is to get a vehicle security system that is integrated by the ignition system on a motorcycle. The process of securing a motorized vehicle when it is stolen is, the security system will send sms information that the motorcycle is stolen, the alarm sounds and the ignition system is cut off. To turn off the alarm and start the motorcycle, the owner sends an SMS with the format *ALOF# to the security system and starts the motorcycle normally (Pull the front brake three times then position the key to ON mode).
