Abstract

The synthesis and characterization of B-type CHAp based on mangrove crab shells (Scylla serrata) as a source of calcium using the precipitation method has been successfully carried out. Based on the FTIR results, the substitution of carbonate ion for phosphate, which indicates the formation of B-type CHAp, is characterized by the appearance of absorption at wave numbers (CO32-) 1426 and 875 cm-1, PO43- at wave numbers 965, 619 & 569 cm-1. The XRD results show that diffraction peaks (211), (300), and (202) appear at an angle of 2θ ranging from 31°-34°, and there is a phenomenon of a-axis contraction and c-axis expansion in the HAp lattice structure. The SEM-EDX results show that the Ca/P ratio is 1.72, and the carbonate content is 5.01 wt%. All of these parameters are characteristics of CHAp, so it can be concluded that type-B CHAp has been formed.

Abstract

In this study, a zeolite/Hydrilla verticillata composite adsorbent was prepared and characterized, and its performance was evaluated for the adsorption of Naphtol Blue Black (NBB) dye. Natural zeolite sourced from Bayah, Banten, was used as the base material. The composite was synthesized using the wet impregnation technique. Characterization was conducted using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). FTIR analysis showed absorption bands at 2919 cm-1, 514 cm- 1, and 1014 cm-1, indicating the successful formation of the zeolite/Hydrilla verticillata composite. XRD results revealed that the Bayah natural zeolite contains modernite and heulandite crystal phases, with an average crystallite size of 9.3 nm calculated using the Scherrer equation. SEM images indicated that the zeolite surface was largely covered by Hydrilla verticillata particles. The adsorption experiment showed that the composite adsorbent achieved a 34.07% removal efficiency of NBB dye. The adsorption process followed the Freundlich isotherm model, with an R2 value of 0.9995 and a maximum adsorption capacity of 13.59 mg/g.

Abstract

AbstrakTim Dosen dan Mahasiswa Informatika Fakultas Sains Universitas Sultan Maulana Hasanuddin Banten telah melakukan Pengabdian kepada Masyarakat (PkM) yang dilakukan di MA Nurul Basmalah Baros guna menjawab permaslahan mitra yakni belum optimalnya penggunaan fitur AI pada desain grafis. Tujuan PkM ini untuk membantu siswa mengenal, mendesign, dan menggunakan fitur AI dengan menggunakan Canva sebagai Tools dalam membuat sebuah desain literasi digital. PkM dilakuka dalam bentuk Pelatihan dengan Peserta pelatihan ini ialah siswa kelas XII MA Nurul Basmallah Baros. Tiga tahapan kegiatan PkM ini meliputi tahap persiapan, tahap pelaksanaan, dan tahap pelaporan. Survei kepuasan dilakukan menggunakan kuesioner, hasilnya menunjukkan bahwa PkM berjalan dengan baik dan dismbut baik oleh mitra. Sesuai dengan hasil survei yang diisi langsung oleh mitra yang terdiri dari indikator kesesuaian materi dengan kebutuhan mitra, serta kejelasan dan kemudahan memahami materi memperoleh 70% Sangat setuju dan 30% setuju, pelayanan Tim PkM dan kebermanfaatan teknologi bagi mitra memperoleh persentase yang sama yakni 80% Sangat setuju dan 20% setuju, waktu pelaksanaan kegiatan memperoleh persentase 65% Sangat setuju dan 35% setuju, serta rencana pelaksanaan tindak lanjut kegiatan memperoleh persentase 90% Sangat setuju dan 10% setuju. Kata kunci: design grafis; AI; Canva; literasi digital Abstract The Informatics Lecturer and Student Team of the Faculty of Science, Sultan Maulana Hasanuddin University, Banten, has carried out Community Service (PkM) at MA Nurul Basmalah Baros to answer the partner's problem, namely the less than optimal use of AI features in Canva graphic design. The purpose of this PkM is to help students recognize, design, and use AI features using Canva as a tool in creating a digital literacy design. PkM is carried out in the training with the participants were class XII students of MA Nurul Basmalah Baros. The three stages of this Pk M activity include the preparation stage, the implementation stage, and the reporting stage. A satisfaction survey was conducted using a questionnaire, the results showed that PkM went well and was well received by partners. In accordance with the results of the survey filled out directly by partners consisting of indicators of the suitability of the material to the needs of partners, as well as the clarity and ease of understanding the material obtained 70% Strongly agree and 30% agree, the service of the PkM Team and the usefulness of technology for partners obtained the same percentage, namely 80% Strongly agree and 20% agree, the time of implementation of the activity obtained a percentage of 65% Strongly agree and 35% agree, and the plan for implementing follow-up activities obtained a percentage of 90% Strongly agree and 10% agree. Keywords: graphic design; AI; Canva; digital literacy

Abstract

AbstrakPengabdian kepada Masyarakat (PkM) dilakukan oleh Tim Dosen Fakultas Sains Universitas Islam Negeri Sultan Maulana Hasanuddin Banten di SMAN 3 Kota Serang yang bertujuan untuk menanamkan pemahaman dan konsep praktikum virtual menggunakan PhET simulation pada materi Konsentrasi. Peserta pelatihan ini adalah siswa kelas XII SMAN Kota Serang. Tahapan kegiatan yakni tahap persiapan, tahap pelaksanaan, dan tahap pelaporan. Kegiatan PkM berjalan lancar dan disambut baik oleh mitra. Hal ini dilihat dari hasil survey yang diisi langsung oleh mitra yang terdidi dari enam indikator kepuasan mitra. Berdasarkan survey terdapat 45% siswa/mitra sangat setuju, 51% setuju dan 4% tidak setuju terhadap pernyataan pada 6 indikator kepuasaan mitra, sementara sangat tidak setuju terhadap 6 indikator kepuasan mitra terdapat 0%. Apabila dilihat pada respon mitra setuju dan sangat setuju maka diperoleh jumlah 96%, sehingga dapat disimpulkan bahwa kegiatan ini dikatakan berhasil karena lebih dari dari 90% mitra merespon baik kegiatan ini. Kata Kunci: virtual lab; PhET simulation; konsentrasi. AbstractCommunity Service (PkM) was carried out by the Lecturer Team at the Faculty of Science, Sultan Maulana Hasanuddin State Islamic University, Banten at SMAN 3, Serang City, which aims to instill understanding and concepts of virtual practicum using PhET simulation in Concentration material. Participants in this training are class XII students at SMAN Kota Serang. The activity stages are the preparation stage, implementation stage and reporting stage. PkM activities ran smoothly and were well received by partners. This can be seen from the results of a survey filled out directly by partners consisting of six indicators of partner satisfaction. Based on the survey, 45% of students/partners strongly agreed, 51% agreed and 4% disagreed with the statement on the 6 indicators of partner satisfaction, while 0% strongly disagreed with the 6 indicators of partner satisfaction. If we look at the partner responses agreeing and strongly agreeing, the figure is 96%, so it can be concluded that this activity was said to be successful because more than 90% of partners responded well to this activity. Keywords: virtual lab; PhET simulation; concentration.
