Abstract

Academic dishonesty is a deliberate violation of academic rules for personal gain. Academic dishonesty can reduce the reputation of students and universities, as well as dishonest behavior in the world of work, so research is needed regarding engineering students' perceptions of academic dishonesty. This study aims to determine perceptions, experiences, reasons why engineering students commit academic dishonesty, and to determine the influence between perceptions and experiences of witnessing acts of academic dishonesty. The population used in this study were S1 students from the UNS Faculty of Engineering and the samples taken were 97 respondents. The results of the study show that engineering students' perceptions of academic dishonesty are that students know that academic dishonesty is important, can have an impact on damaging moral character, including actions that violate social and religious norms, so that it becomes the student's responsibility, and must be responsible for caring for the integrity of other students. . The experience of engineering students with academic dishonesty is that students have committed dishonesty but support existing policies, often use unauthorized material during exams, work on papers or articles without including references, and ask for help from seniors who have taken exams but rarely submit assignments properly. pay someone else to complete it and rarely miss out on group assignments. Academic dishonesty policies already exist but sanctions and supervision need to be tightened to reduce academic dishonesty. The reason engineering students commit academic dishonesty is because they don't get sanctioned or punished, the attitude of the lecturer, many friends who do this, will make grades better, difficulty working on questions, easy internet access and fear of failure and lack of study time. Most of the respondents committed academic dishonesty due to internal factors. There is a positive and significant influence between perception and experience of witnessing techniques on the experience of committing academic dishonesty. So that when the perception and experience of witnessing gets higher, they will not commit academic dishonesty.

Abstract

This study aims to analyze differences in thermal properties, including thermal stability and the change in melting temperature (Tm) on variations in the mass fraction of fiber in mPP/bamboo fiber composite materials. Disposable face mask waste or mask polypropylene (mPP) is used as a polymer matrix and bamboo (Dendrocalamus asper) fiber as a composite reinforcement. The method used in this research is experimental. Variations in the mass fraction of bamboo fiber used were 0%, 4%, 8%, and 12%. Size of the bamboo fiber used is 5 mesh and has been treated with 5% NaOH alkali for 2 hours. The composite manufacture consists of two stages, namely the manufacture of mPP/bamboo fiber fragments by melting mask waste that has been mixed with bamboo fiber using an oven at 180°C for 2 hours. In the second stage, the mPP/bamboo fiber fragments were processed using an extruder machine with a processing temperature of 150°C and a screw speed of 25 rpm. Composite specimens measuring 2 x 2 x 2 mm with a weight of 1 to 10 mg were tested by TGA and DSC using a temperature of 25 to 900°C with a heating speed of 10°C/min in an oxygen atmosphere. The results of the thermogravimetry analysis (TGA) test showed that the neat mask polypropylene (mPP) without bamboo fiber reinforcement had the best thermal stability compared to other fiber mass fractions. The results of the differential scanning calorimetry (DSC) test showed that the mPP/0% bamboo fiber had the best melting temperature (Tm) at a temperature of 156.16˚C compared to other fiber mass fractions in the temperature range of 155°C to 156°C.

Abstract

The main purpose of this study was to determine the effect of variations in gamma ray dose on the physical and mechanical properties of natural fiber reinforced polymer blend composites. The method used in this research is experimental. This research was conducted on polymer blend composites, namely recycled High Density Polyethylene (rHDPE) and recycled Polypropylene (rPP) with bamboo fiber reinforcement with variations in gamma ray doses of 0 kGy, 25 kGy, 50 kGy, and 75 kGy. Bamboo is processed using a crusher into fibers with a size of 40 mesh and treated with 5% NaOH alkali for 10 minutes then dried using oven for 24 hour at a temperature of 105 °C to remove lignin contained in bamboo fibers. The composite was made using two machines, namely an extrusion machine with a heater temperature of 175 °C, 180 ºC, 185 ºC, and 190 ºC with a screw speed of 25 rpm. Then the injection molding machine with a temperature of 220 ºC with a specimen mold temperature of 90 ºC and an injection pressure of about 45 bar for 20 minutes. Gamma ray treatment was carried out after making the specimen before testing. Where a gamma cell irradiator is used and as a source of gamma rays, cobalt-60 (Co-60) is used. Tensile and water absorption tests are used to determine the physical and mechanical properties of the composite material according to ASTM D638 type V and ASTM D570-98 standards. The test results showed that the higher the dose used, the lower the physical and mechanical properties of the composite. The highest tensile strength was found at the 25 kGy dose treatment of 13.68 MPa and the lowest at the 75 kGy dose treatment. The lowest water content absorption and thickness expansion after 144 hours of immersion were at a 50 kGy gamma dose of 3.43% and 1.27%, respectively. Meanwhile, the highest condition was found at the 75 kGy gamma ray dose of 3.79% and 1.42%, respectively.
