Abstract

Banjarwaru Village, Nusawungu District, Cilacap Regency, has natural resources, especially eucalyptus plants, which have the potential to develop the economy of the village community. The biggest problem faced by LMDH Dadi Makmur as a unit that manages the eucalyptus oil business is that after the production of eucalyptus oil distillation, it will produce residual waste from eucalyptus twigs and leaves with quite a large volume and only allowed to be piled up around the yard where the distillery is, causing area storage of essential oil raw materials is narrow and also takes a long time to become organic fertilizer. The innovation offered through this community service activity is implementing a briquette printing machine from eucalyptus oil refining waste, which is energy efficient and based on solar panels. The dedication results show that the eucalyptus oil waste processing activity and reducing environmental pollution also produce biomass briquettes that the residents of Banjarwaru Village can utilize as a leading economic product of Banjarwaru Village. The test data of the briquette making machine shows that the output voltage from the inverter produces an AC voltage with a value of 216 - 221 V, so that it can rotate the AC motor with a rotation of 800 - 1400 rpm.

Abstract

Limbah cair dari industri batik, terutama yang mengandung bahan kimia berbahaya seperti pewarna sintetik dan logam berat, menjadi masalah lingkungan yang signifikan di berbagai wilayah industri batik, termasuk Cilacap. Penelitian ini mengeksplorasi penerapan teknologi elektrokoagulasi sebagai metode pengolahan limbah batik, dengan fokus pada optimasi proses dan integrasi sistem filtrasi-adsorpsi. Proses elektrokoagulasi terbukti efektif dalam menurunkan parameter kualitas air, seperti BOD, COD, TSS, dan konsentrasi logam berat, seperti kromium, yang pada akhirnya memenuhi standar baku mutu yang ditetapkan oleh regulasi lingkungan (PERDA No. 5 Tahun 2012 Provinsi Jawa Tengah). Hasil penelitian menunjukkan penurunan signifikan pada BOD, COD, TSS, dan kromium, dengan penerapan sistem filtrasi-adsorpsi lebih lanjut meningkatkan efektivitas pengolahan. Penelitian ini memberikan kontribusi ilmiah yang signifikan dalam menawarkan solusi pengolahan limbah yang ramah lingkungan dan berkelanjutan untuk industri batik, dengan potensi adopsi yang lebih luas di tingkat global. Teknologi ini tidak hanya mengurangi dampak negatif limbah terhadap lingkungan tetapi juga memungkinkan limbah batik untuk diproses kembali menjadi produk berguna, seperti malam (candle wax). Temuan ini menunjukkan potensi penerapan teknologi elektrokoagulasi dan filtrasi-adsorpsi sebagai solusi inovatif untuk pengelolaan limbah industri batik secara global.

Abstract

Education is progressing faster than at any other time in history. Educators are becoming increasingly conscious that today's learning media are developing to match future realities. Education must establish new approaches in the learning process by employing virtual classrooms and tools and technology. The virtual classroom concept offers a solution for today's and tomorrow's educational needs. To prepare for future employment, students require a holistic education that combines practical occupational skills, communication methods, and leadership development. This paper will give a bibliometric analysis of the term virtual classroom as a learning media, focusing on future research trends in vocational education. The articles were obtained with the help of the Publish or Perish software and the Scopus database. With a search period spanning 2013 to 2022, 405 articles were evaluated (9 years period). The desktop version of the Mendeley program is used to handle the references. VOS Viewer software was used to classify the articles by generating six clusters. The main keywords from the six groupings are virtual reality, e-learning, teaching, education, augmented reality, and improved classroom instruction.

Abstract

Electrospinning is a modified technology to produce nano-sized fibers which can be used in making thin layers of semiconductor dye sensitized solar cells. Flourate – doped tin oxide (FTO) substrate was placed as a target for deposition of TiO2 nanofiber synthesized from TiO2 solution. The deposition process of a thin layer of TiO2 nanofiber was carried out for 15 minutes. The TiO2 solution synthesized is a mixture of acetic acid, ethanol, polyvinylpyrrolidone (PVP), and titanium tetra – isopropoxide (TTIP). Mixing the synthesis solution was carried out for 24 hours, to obtain a homogeneous TiO2 synthesis solution. The TiO2 nanofiber thin layer deposition process was applied under an electrospinning voltage of 25 kV, the distance of the FTO substrate as the collector layer to the solution syringe was 25 cm to avoid too large solution droplets. Before the deposition stage, the surface of the FTO substrate is first formed using the etching method by coating Zn and removing the conductive layer using HCl, so that a customized conductive layer is obtained. The annealing process of the deposited TiO2 nanofiber layer was carried out for 3 hours at a temperature of 450°C. The spin coating method was carried out to deposit a layer of Poly [2- methoxy- 5- (2- ethyl hexyloxy)- 1,4- phenylene venylene] (MEH-PPV). Coating variations are carried out with 4 different layer thicknesses. MEH – PPV was prepared by mixing chlorobenzene and stirring for 18 hours. Testing and characterization was carried out using current and voltage characterization (I – V meter), as well as image characterization using Scanning Electron Microscopy (SEM) as an analysis of the influence of layers on organic solar cells.

Abstract

A coil winding machine for water pumps using a monitoring system is a development of conventional winding tools. In regular coil winding tools, the coil winding process is done manually by rotating the handle as many times as the desired number of turns. The conventional winding tools have problems consisting of inconsistent working speed and operator-dependent winding continuity. Undesirable windings can occur with conventional winding tools, and the winding process requires close supervision. Therefore, the automatic coil winding machine was developed to optimize the coil winding process. The machine utilizes a DC motor to rotate the coil rolls, replacing the conventional roller handle function. This machining method uses an optocoupler sensor. The sensor serves to identify and evaluate the rotation of the roller. In addition, the ATmega8 microcontroller was applied to develop a system that can work automatically. Data collection involves varying the number of wire turns and the wire diameter dimension. The variation is necessary because the number of windings and wire diameter affect pump efficiency and performance. The data testing showed a machine accuracy rate of 98%, with a maximum difference of 1 coil winding in the results. This data confirms that the coil winding machine meets the tool's accuracy standards.
