Abstract

Ikan lele merupakan salah satu ikan budidaya yang banya digemari oleh masyarakat Jawa Timur sehingga permintaannya setiap tahun semakin meningkat. Seiring meningkatnya permintaan yang meningkat tidak diimbangi dengan pengelolaan kualitas air yang baik. Salah satu penyebabnya karena kurangnya pemahaman petani ikan akan pentingnya penerapan teknologi dalam proses budidaya ikan. Oleh karena itu, perlu adanya pemberdayaan masyarkaat melalui Pengabdian kepada masyarakat mengenai penerapan teknologi dalam budidaya ikan. Program Pengabdian Kepada Masyarakat ini akan berfokus pada satu mitra yang saat ini tengah mengembangkan usaha perikanan budidaya lele, yaitu Kelompok Budidaya Ikan (Pokdakan) ROI LELE. Pokdakan ROI LELE berada di desa Bringin, kecamatan Wajak, Kabupaten Malang, Provinsi Jawa Timur. Metode pelaksanaan PKM ini meliputi memberikan pelatihan dan pendampingan mengenai penerapan teknologi Microbubble Generator (MBG) yang terkoneksi dengan Internet of things (IOT). Sistem MBG ini dilengkapi sensor untuk sistem monitoring kadar oksigen terlarut dan pH dengan mengintegrasikan konsep IOT untuk memonitor dan mengendalikan MBG secara otomatis maupun manual melalui kontrol smartphone. Berdasarkan hasil penerapan MBG dan IOT pada kolam ikan lele didapatkan hasil kadar oksigen terlarut meningkat dan menjaga pH perairan tetap stabil sehingga mendukung kelangsungan pertumbuhan ikan lele. Selanjutnya, capaian dari PKM ini ialah adanya peningkatan pengetahuan dan keterampilan petani ikan serta peningkatan kapasitas produksi ikan lele dengan adanya penerapan MBG dan IOT.

Abstract

Bacterial cellulose (BC) is a widespread, low-cost biopolymer that has generally been produced from plants and biomass waste. A method for improving the range of applications for bacterial cellulose is adding graphene material. It has an outstanding feature that can increase the performance of nanocomposite materials. The research aims to observe the effect of graphene on the surface morphology, crystallinity, chemical bonding, and tensile strength of BC/CuO nanocomposite. For this study's synthesis, BC was synthesized by fermenting pineapple peel extract for 10 to 14 days. The produced BC was crushed, homogenized with a nano homogenizer machine, and filtered. Filtered BC, CuO, and graphene were added to obtain a solution, and the mixture was first stirred magnetically, followed by an ultrasonic homogenizer, and finally dried using a freeze-dry method to make a porous nanocomposite. According to SEM analysis, the addition of CuO and graphene can fill porosity nanocomposite. By XRD analysis, the addition of graphene reduces the crystallinity of BC/CuO. The FTIR data showed that adding graphene reduces hydrogen bonding and makes some Cu-O-C bonding. The tensile test has demonstrated that the tensile strength of BC-based nanocomposite with graphene reinforcement tends to decrease.

Abstract

Natural fibers, which are abundant, environmentally friendly, and biodegradable, are used as a replacement for synthetic fibers. The composite strength can be increased by treating the surfaces of natural fibers with suitable chemicals, which can also improve the interface interaction between fiber and matrix. Application of a coupling agent in chemical treatment is utilized to reinforce the bonding between fiber and matrix. The objective of the study is to determine the influence of silane concentration on the Sansevieria cylindrica fiber properties. The methods included fibers treatment using ethanol and coupling agent as dissolving and TiO2 with concentrations of 0 percent, 0.25 percent, 0.5 percent, 0.75 percent, and 1 percent. The mechanical strength testing was conducted through a single fiber test. Fiber morphology was observed using an electron microscope. FTIR analyzes the change in fiber chemical composition caused by TiO2 addition. As a result, the morphology of S. cylindrica fibers became rougher and showed a rougher surface after a silane concentration of 1 percent, but with the proper concentration, some fiber surfaces provided a good interface. Ti-O bonds are formed at a wavelength of 475 cm-1. The shift in a peak at 400–500 cm-1 indicates Ti-O-Ti group stretching vibrations believed to have originated from TiO2 particles. The mechanical strength increases as the concentration of TiO2 increases, with the highest fiber strength of 284.66 MPa observed at a TiO2 concentration of 1 percent. This represents a 26 percent higher tensile strength compared to the control specimen.

Abstract

This study aims to analyze the effect of filament feeding length, nozzle distance and varied printing speeds on the thickness and length of the filament fiber of the 3D Printer FDM machine. This research method is experimental, while the test results were analyzed using the Taguchi method and analysis of variance (ANOVA) using the Minitab software. The concept used is by utilizing the surface tension on the stretched filament or commonly known as the liquid bridge phenomenon. This method is possible to make thinning of the extruded filament. The lower extrusion volume thickness and higher printing speed are concluded to produce micro-sized fibers due to the smaller viscoelastic internal compression force along the filament fiber. This study uses variations in filament feeding length (0.2 mm, 0.3 mm, 0.4 mm), nozzle distance (0.6 mm, 0.7 mm, 0.8 mm) and printing speed (1000 mm/min), 1500 mm/min, 2000 mm/min). The results of the analysis of the thickness of the filament fiber obtained the optimal variation of filament feeding length 0.2 mm, printing speed 2000 mm/min, and nozzle distance 0.8 mm which resulted in a thickness of 120 m. The results of the analysis of the length of the filament fiber obtained the optimal variation of filament feeding length of 0.4 mm, printing speed of 1000 mm/min, and nozzle distance of 0.6 mm which resulted in a length of 3 cm. Penelitian ini bertujuan untuk menganalisa pengaruh filament feeding length, jarak nozzle dan kecepatan cetak yang divariasikan terhadap ketebalan dan panjang serat filament mesin 3D Printer FDM. Metode penelitian ini menggunakan eksperimental, sedangkan hasil pengujian dianalisis dengan metode Taguchi dan analysis of variance (ANOVA) menggunakan software Minitab. Konsep yang digunakan yaitu dengan memanfaatkan tegangan permukaan pada filament yang ditarik memanjang atau biasa disebut dengan fenomena liquid bridge. Metode ini dimungkinkan dapat membuat penipisan pada filament yang di ektrude. Ketebalan volume ekstrusi yang lebih rendah dan kecepatan pencetakan yang lebih tinggi disimpulkan dapat membuat serat dengan ukuran mikro karena gaya kompresi internal viscoelastic yang lebih kecil di sepanjang serat filament. Penelitian ini menggunakan variasi filament feeding length (0,2 mm, 0,3 mm, 0,4 mm), jarak nozzle (0,6 mm, 0,7 mm, 0,8 mm) dan kecepatan pencetakan (1000 mm/min, 1500 mm/min, 2000 mm/min). Hasil analisis ketebalan serat filament didapatkan variasi optimal filament feeding length 0,2 mm, kecepatan pencetakan 2000 mm/min, dan jarak nozzle 0,8 mm yang menghasilkan ketebalan 120 μm. Hasil analisis panjang serat filament didapatkan variasi optimal filament feeding length 0,4 mm, kecepatan pencetakan 1000 mm/min, dan jarak nozzle 0,6 mm yang menghasilkan panjang 3 cm

Abstract

In many polymer compounds, Polylactic Acid (PLA) is a polyalcohol material that has the most potential material which is potent for biological degradation. They have been applied as filaments in additive manufacturing. The PLA properties can be modified by adding nanomaterials such as graphite nanoplatelets. This study aims to obtain the characteristics of PLA-based filament nanocomposite with nanographite reinforcement. Methods include exploration research to obtain nanocomposite filament with PLA and 1% of nanographite. The mixing process of nanographite in PLA solution with chloroform solvent and then the extrusion process of nanocomposite using a single extruder. The product comparison before and after the extrusion process was analyzed using X-ray diffraction and Fourier Transform infrared. Diffractogram results indicate that the original PLA structure is amorphous, and after mixing using nanographite, peaks of nanographite appeared clearly. After the extrusion process, some peaks at 16.7° and 19.1° disappeared, but only a peak 26.6° appeared in the diffractogram. Extrusion makes the structure change. Functional group analysis confirms that some reactions occurred so that many peaks were removed, and several new peaks were observed. It indicates that the extrusion process of PLA/nanographite results in different structures and functional groups that indicate a change in its properties.
