Abstract

Suji leaves are one of the new materials that can form natural fibers. Suji leaf fiber is fiber obtained from suji leaves. Suji leaf fiber is one of the new materials that can be made into composite materials. The aim of this study was to determine the effect of immersing leaf fiber on liquid smoke and NaOH with fiber volume fractions of 15%, 20% and 25%, angular orientation (0°) and soaking times of 1 hour, 2 hours and 3 hours. Making composites using the hand-lay up method. Sampling using the full factorial method. The highest bending test result was in immersion of liquid smoke of 48.23 MPa at 25% fiber percentage with 1 hour immersion time. This means that the longer the soaking process of suji leaves with liquid smoke will decrease the flexural strength. The highest flexural test result was in NaOH immersion of 40.6 MPa at 20% fiber percentage with 3 hours of immersion time. This means that the longer the soaking process with NaOH will increase the flexural strength. Based on the BSAPI standard from the results of the bending test, the results obtained in this study cannot be used for making wall climbing panels because they do not meet the requirements, namely 112.8 Mpa, but for the manufacture of other materials such as car dashboards which have a type of High Impact ABS plastic material. 37-76 MPa.

Abstract

Silencer is a tool to reduce the intensity of sound that occurs. Many have developed natural fibre-reinforced composite materials as an alternative to silencers, as they are considered more environmentally friendly than synthetic fibres and relatively cheaper. Resam plants are found in the Bangka Belitung area so that the availability is quite abundant. The purpose of this research is to test the sound absorption coefficient of resam fibre with polyester matrix as an alternative material for soundproofing. Making specimens using the hand lay-up method and research design using the full factorial method. The process variables used were volume fraction of 5%:95%, 10%:90%, 15%:85% and NaOH soaking time of 60, 90, 120 minutes and testing frequency of 500 Hz and 1000Hz. Based on the test results, the highest sound absorption coefficient was obtained in the variation of volume fraction of 15%: 85% volume fraction variation and the immersion time of NaOH solution for 90 minutes at a frequency of 500 Hz was 0.375. While the lowest sound absorption coefficient value in the variation of 5% volume fraction: 95% and the immersion time of NaOH solution for 90 minutes at a frequency of 1000 Hz was 0.16. Based on ISO 11654, the results obtained from this study, resam fibre filler composites can be used as an alternative sound absorbing material because it has exceeded the minimum value of 0.15.

Abstract

An UMKM (micro, small and medium scale business) in the city of Pangkalpinang, Province of Kep. Bangka Belitung, with the trademark "kebajig Lure", produces metal jigs or artificial/fake bait made of metal. One of the problems in the process of making metal jigs at UMKM is bending the wire on the metal jig, because the bending process uses loop pliers which causes the wire to be made to be non-uniform (where 10 wires, below 50% of the wire deviates from tolerance) so that the stray wire must be repaired first before the metal jig molding process. In addition, the bending time of 1 piece of wire takes about 80 seconds. This study aims to accelerate the metal jig bending process and to obtain a uniform wire with a deviation of ± 0.2 mm. After conducting the survey and initial analysis, the making of tools for bending wire is the solution. In the process of making these tools, the VDI 2222 design method is used, starting from planning, conceptualizing, designing, and finally finishing. Then carried out the process of making tools and testing wire bending. The results of the experiments conducted showed that the uniformity level of the metal jig wire was around 70% and the time required in the 1-wire bending process was ± 10 seconds, with an efficiency of ± 70 seconds from the previous process. And in the metal jig molding process, the wire repaired before the molding process is only about 30%.

Abstract

Technological developments and advances in the industrial sector have led to the increasing use of metals. This condition causes the availability of metal raw materials to decrease. Overcoming this, the use of composites in the industrial world is a solution. Many composite reinforcing materials use natural fiber materials are often used because they have advantages in strength and stiffness that are higher than other engineering materials. In this study using a factorial experimental method that looks at the effect of the composite ratio (volume fraction) with the use of 2 natural fiber mixtures, namely resam fiber and areca nut on impact strength. This study aims to determine the average difference in each treatment carried out in the impact test. The volume fraction treatment variants used in this study are 25%; 30%; 35% resam fiber and 10% areca nut fiber with a long soaking time of 2% NaOH mixed fiber for 2 hours with the α value used is 5%. It was found that in treatment 1: 2 the average value is different while in the treatment of 2: 3 and 1: 3 the average value of the variables is not different.

Abstract

Natural resources in the form of solar heat, can be used as an alternative to electricity generation by using a power plant tool in the form of solar panels. In certain areas there are still many who need a supply of electric power, for example in the Turun Aban Sungailiat Beach area, Bangka Belitung Islands Province. At that location there is no electric power supply at all, the fishermen at the Turun Aban Beach location often carry out the process of transporting catches at night conditions. Therefore, to meet their needs, these fishermen can use alternative power plants in the form of solar panels. This research examines the process of analyzing the performance of solar-powered power plants. The solar panel produces 115.28 watts of power in 1 day. The time required for charging the battery is 5.81 hours/day and the battery endurance time is 4.65 hours in 1 day.
