Abstract

In this millennial era, there are many school institutions that use modern technology in carrying out learning, to support and make learning more interesting. One example of modern technology that can be used is Augmented Reality technology. Unfortunately the use of Augmented Reality technology is not as easy as imagined, because there are obstacles such as the lack of teacher education about various learning media that support the learning process and also especially on the location factor of RA Babul Ulum which is in rural areas so that it has not been touched by learning media that smells technology. To support learning using the AR system at RA Babul Ulum, Pulau Panggung village, North Lampung, a community grant team from the State University of Malang funded by PNBP carried out a community service program in the form of counseling and providing teaching aids in the form of an LCD projector and also several Augmented Reality (AR) cards.). With the methods of observation, lectures, demonstrations, discussions and practice with direct trials resulted in: teachers RA Babul Ulum understand and master the application of Augmented Reality technology; RA Babul Ulum received new teaching materials in the form of Augmented Reality cards; The use of this learning media causes students to understand better and not get bored easily when the learning process takes place.

Abstract

Tujuan dari kegiatan ini adalah untuk meningkatkan kemampuan mengenal huruf hijaiyah awal pada siswa Taman Kanak-kanak (TK) ‘Aisyiyah Bustanul Athfal 16 Kota Malang dengan pemanfaatan media pembelajaran berupa alat permainan edukatif. Alat permainan edukatif ini bernama “Petak Pintar” yang mengambil konsep dari permainan tradisional engklek. Dengan sedikit modifikasi dan improvisasi, penggunaan alat permainan edukatif petak pintar ini dapat membuat pembelajaran menjadi lebih menyenangkan. Kegiatan pengabdian kepada masyarakat ini melibatkan lembaga sekolah TK ‘Aisyiyah Bustanul Athfal 16 Kota Malang sebagai mitra yaitu 6 orang guru dan 20 orang anak didik kelas B1, serta tim dari Universitas Negeri Malang. Hasil dari kegiatan pengabdian pada masyarakat ini adalah meningkatnya kemampuan mengenal huruf hijaiyah awal sesuai dengan yang ada dalam petak pintar tersebut. Kemampuan yang terdapat dalam pengembangan alat permainan edukatif petak pintar yaitu anak dapat mengenal warna (pada petak dan gaco), anak mampu mengenal macam-macam bentuk geometri (persegi panjang, persegi, dan setengah lingkaran), menyebutkan lambang huruf hijaiyah, menuliskan lambang huruf hijaiyah pada papan tulis yang telah disediakan, memasangkan 2 sampai 3 huruf hijaiyah sesuai perintah melalui gambar pada kartu.

Abstract

Nanolubricant is a type of nano fluid that contains base-fluid lubricant (water or oil) and nanoparticles. This study aims to analyze the thermophysical and rheological properties of lubricants with the addition of nanoparticles. The nanoparticles used are Calcium Carbonate (CaCO3) made from scallop shell waste. The base lubricant is SAE 5W-30 synthetic oil which has quite good performance. Synthesis of Calcium Carbonate (CaCO3) into SAE 5W-30 lubricant uses a two-step method. Variations in the addition of volume fraction of Calcium Carbonate (CaCO3) of 0.05%, 0.10%, 0.15%. Furthermore, the nanolubricant was tested for its thermophysical properties which included thermal conductivity, specific heat, density, viscosity, and sedimentation. After that, the rheology of the nanolubricant can be known from the viscosity data by calculating the shear rate and shear stress.

Abstract

This research uses SAE 5W-30 lubricant base material with the addition of Hexagonal Boron Nitride (hBN) nanoparticle additives. This study aims to analyze the thermophysical and rheological properties of lubricants with the addition of nanoparticles. The method in this study uses a two-step method where nanoparticles are first prepared separately, then added with nanoparticles with varying volume fractions of 0.05%, 0.10%, 0.15% into the base fluid as a processing step. The next step is the stirring process using a magnetic stirrer, and ultrasonic homogenizer process.  Furthermore, the nanolubricant was tested for thermophysical properties including viscosity, density, thermal conductivity, and sedimentation.

Abstract

DSFSW welding uses the rotating of a tool in the workpiece to create heat owing to friction between workpiece and tool to be connected. Corrosion is influenced by the presence of high heat owing to friction and a non-uniform cooling rate. The heat transforms the metal in the Heat Affected Zone (HAZ) and Weld Metal (WM) region, which can result in flaws such porosity, kissing bond, fractures, voids (from welding penetration), and flash as well as changes to the microstructure. Changes in the microstructure of welded joints can affect the resistance of welded joints to corrosion. The purpose of this study is to experimentally analyze the main causes of failure of AA6061 DSFSW joints based on welding temperature, weld defects, microstructure, corrosion rate and morphology of the corroded surface. Temperature testing using thermocouple to analyze the temperature, welding joint defects using DSLR camera and radiography test, microstructure using optical microscope, corrosion rate using AUTOLAB PGSTAT and morphology of corroded surface using SEM. The temperature analysis results show that the advancing side has a higher temperature than the retreating side, due to friction between the tool and base metal accompanied by the opposite welding direction. Visual inspection shows that all specimens and welding positions produce flash that is quite rough on the top (1G) and bottom (4G) surfaces and radiographic test results show incomplete fusion in 4 specimens. Microstructure shows a change in shape and size resulting in recrystallization in the form of fine grains. The highest corrosion rate is found in specimen B 1G welding position of 0.63856mm/year and the lowest corrosion rate in specimen A of 0.058567mm/year. SEM test results show the type of corrosion that occurs in DSFSW welding joints is pitting corrosion.

Abstract

This study is motivated by the depletion of fossil fuels in nature, which is inversely proportional to the higher level of fuel oil consumption, so the need for alternative fuels, namely biodiesel. Biodiesel can be made using waste cooking oil because of its abundant quantity, low price, and not being reused. One of the efforts to achieve energy conservation and improve fuel quality is using bioadditives. A lemon essential oil can be used as a bio-additive because it is easily soluble in fuel and its oxygen-rich content can reduce the rate of fuel consumption. The process in this study is to produce biodiesel with waste cooking oil (WCO) using a transesterification process. Biodiesel samples containing the bioadditive lemon essential oil on B20 biodiesel with varying volume fraction (0%; 0.1%; 0.15%; 0.2%). In general, this research can be done in three steps. The first step is the characterization of the compound composition (GCMS) and functional group (FTIR) of diesel fuel, biodiesel, and lemon essential oil bioadditive. The second step is the characterization of the physicochemical properties (density, viscosity, flash point, calorific value) of B20 biodiesel with various concentrations of lemon essential oil bioadditive, then compared with SNI 7182:2015. The third step is determining the rate of fuel consumption in diesel engines. The results show that Biodiesel B20 with a volume fraction of 2% lemon essential oil bioadditive has a high ability to reduce the rate of fuel consumption.
