Abstract

As a form of concern for the issues faced by the descendants of Indonesian nationals in Malaysia, especially for the Human Resources, we provide the unique theoretical and practical chemistry mentorship for future capability. Sanggar Bimbingan Sungai Mulia 5 is an organization that offers educational services for Indonesian descendants whose citizenship status is still unclear due to administrative reasons. Based on the Chemistry Department UM and Sanggar Bimbingan Mulia cooperation, It is important to enhance the nation's intellectual capacity, especially in ensuring the success of the mandatory 9-year education program. This community service aims to combat illiteracy, in still character education, and prepare students for higher education. The expected outcomes of this program is a unique chemistry Massive Open Online Course (MOOC), a service article published, a service report, and a poster. Our program successfully developed the interest of children to love a simple chemistry experiment and improved for reading and learning through various MOOC, books, and educational materials.

Abstract

The issues faced by the sons and daughters of Indonesian citizens (WNI) in Malaysia are social inequality, access to education, and a sense of community involvement. Sanggar Bimbingan Sentul, as a partner, provides learning facilities for WNI's children to solve these three main problems. We initiated to apply the program of MAWIRAKI (Matahari Kewirausahan Kimia) with chemistry study and entrepreneurship program through the Pengabdian Kemitraan Luar Negeri (PKLN) grant by Universitas Negeri Malang (UM). This program integrated by computer training with MS-Word and Paint programs, chemistry daily-life experiments, and the art of batik craft. The results of learning process WNI's children shows that 18 favored students in the Paint program and 10 in the MS Word program during computer training. The "Where's Vitamin C" experiment garnered support from 17 students, highlighting an interest in chemistry study. These activities involved the batik ecoprint and jumput, which received a positive response, with 15 students favoring batik jumputan and 11 choosing batik ecoprint. The WNI's children interest data during the learning process as the foundation and our spirit for developing programs to unearth the entrepreneurial potential and creativity of the younger generation.

Abstract

In a modern era that increasingly values health and sustainability, the demand for natural and environmentally friendly personal care products continues to grow. One response to this trend is the development of organic soaps produced from various natural ingredients. In this study, organic soap using Samia cynthia ricini silkworm cocoon extract has been synthesized. This study aims to assess the quality of organic soap synthesized from silk cocoon extract based on the Indonesian National Standard (SNI) quality criteria and its antibacterial potential. Silk cocoon soap is made from a mixture of silk cocoon extract with palm oil, coconut oil, olive oil, sodium hydroxide, and water. The quality measurements include organoleptic tests, pH, moisture content, total fat, insoluble substance in ethanol, and free fatty acids, based on SNI No. 4085: 2017 and 3532: 2016. Antibacterial testing is conducted by disc diffusion. The results showed that the synthesized silk cocoon soap has a yellowish-white color, a hard density, and no odor. The quality criteria of the soap meet the established standards, with a pH of 9.66, a water content of 11.47%, total fat of 75.00%, ethanol-insoluble substances of 0.52%, and free fatty acids of 1.58%. The soap also demonstrates antibacterial potential that describes by a larger diameter of the inhibitory area against Staphylococcus aureus bacteria.

Abstract

This research aims to synthesize silica-coated nanomagnetite EDTA functionalized (Fe3O4@SiO2-EDTA) to characterize its properties and test its ability to bind Co(II) metal ions. This research was carried out in several steps, including Synthesis of nanomagnetite and characterization via SEM, VSM, XRD, and FTIR; (2) Synthesis of nanomagnetite-coated silica (TEOS) and characterization via SEM, VSM, (3) Synthesis and characterization of silica-coated nanomagnetite with EDTA functionalization (Fe3O4@SiO2-EDTA), and characterization was carried out via SEM, VSM, XRD, and FTIR. (4) Adsorption ability test of Fe3O4@SiO2-EDTA as a Co(II) metal ion adsorbent. EDTA-functionalized silica-coated nanomagnetite was successfully synthesized. Confirmation and characterization of the synthesized material was performed on the basis of the FTIR spectrum band at wavenumber 687 cm-1, which confirmed the formation of magnetite, whereas the absorption band at wavenumber 1092 cm-1 confirmed the formation of a silica coating, and the peak at wavenumber 1617 cm-1 confirmed EDTA functionalization in the material. The peak of the XRD chromatogram is shown in XRD pattern 2, which confirms nanomagnetite, and in silica-coated nanomagnetite, the resulting characteristic peak is the same as the characteristic peak in Fe3O4 except in region 24, which confirms the presence of the silica coating. The magnetization of nanomagnetite before coating was 57 emu/g and that after coating was 48 emu/g. The maximum adsorption ability of the synthesized material for Co(II) ions was 0.1336 mg/g.

Abstract

Ekstraksi Fasa Padat Magnetik telah dikembangkan sebagai suatu metode pemisahan dengan menggunakan adsorben bersifat magnetik. Adsorben terdiri atas inti magnetis yang disalut dengan pelapis. Penelitian ini mensintesis nanomagnetit terlapis silika terfungsionalisasi Ethylenediaminetetraacetic Acid (EDTA) sebagai adsorben ion nikel(II). Proses sintesis dan karakterisasi adsorben dalam penelitian ini meliputi 1) Ekstraksi silika dari pasir kuarsa, 2) Sintesis nanomagnetit menggunakan metode kopresipitasi, 3) Pelapisan nanomagnetit menggunakan silika hasil ekstraksi untuk menghasilkan Fe3O4@SiO2, 4) Fungsionalisasi nanomagnetit terlapis silika dengan EDTA melalui perantara 3-Aminopropyltriethoxysilane (APTES). Hasil ekstraksi dan sintesis yang diperoleh kemudian dikarakterisasi menggunakan instrumen X-Ray Fluorescence (XRF) untuk mengetahui kadar kandungan hasil ekstraksi, Fourier Transform Infra-Red (FTIR) untuk mengetahui spektra khasnya, X-Ray Powder Diffraction (XRD) untuk mengetahui kristalinitasnya, Scanning Electron Microscope (SEM) untuk mengetahui morfologi permukaannya, serta Vibrating Sample Magnetometer (VSM) untuk mengetahui sifat kemagnetan. Kemampuan adsorpsi maksimal adsorben untuk mengikat ion nikel(II) ditentukan dari persentase massa ion nikel(II) terbesar yang diserap per gram adsorben pada uji variasi persentase ion nikel(II) terhadap variasi massa adsorben. Karakterisasi menggunakan XRF menunjukkan ekstraksi silika memiliki komposisi oksida SiO2 sebesar 99,2%. Karakterisasi FTIR menunjukkan puncak serapan pada 1067 cm-1 berkorelasi dengan ikatan Si-O silika hasil ekstraksi. Puncak serapan 687 cm-1, 1033 cm-1, dan 1510 cm-1 berkorelasi dengan ikatan Fe-O, Si-O, dan C=O pada nanomagnetit terlapis silika terfungsionalisasi EDTA. Hasil karakterisasi menggunakan XRD menunjukkan kesamaan antara pola difraksi hasil sintesis dengan pola difraksi nanomagnetit pada JCPDS No. 19-0629. Nanomagnetit berukuran 37-46 nm dan memiliki kekuatan magnetik sebesar 57 emu/g.

Abstract

Kegiatan pendampingan masyarakat dalam pengembangan perencanaan Masjid Al-Barkah di Cipedak, Ciganjur, Jakarta Selatan ini merupakan kegiatan pengabdian pada masyarakat yang dilakukan oleh Program Studi Arsitektur, Fakultas Teknik, Universitas Muhammadiyah Jakarta. Kegiatan ini merupakan salah satu bentuk kepedulian Program Studi Arsitektur FT UMJ dalam upaya meningkatkan kualitas dan kemampuan masyarakat baik dalam menentukan keputusan dalam hal ini sebagai pemegang keputusan, maupun kemampuan dalam menerjemahkan sebuah kebutuhan ke dalam skematis desain. Pelaksanaan kegiatan ini bertujuan untuk mendampingi masyarakat khususnya para pengurus masjid dan pemangku keputusan di dalam masyarakat dalam memberikan solusi desain pada perencanaan pengembangan bangunan masjid yang semula hanya satu lantai menjadi dua lantai. Kegiatan pendampingan ini dilakukan dalam tiga tahapan kegiatan, tahap pertama meliputi observasi lapangan, kegiatan kedua berupa diskusi kelompok antar warga dan pengurus masjid dalam menentukan kebutuhan dan memberikan keputusan-keputusan terkait desain pengembangan dan tahap terakhir adalah eksekusi dari desain pengembangan perencanaan Masjid Al-Barkah yang dibantu oleh para mahasiswa Program Studi Arsitektur FT UMJ. Hasil akhir dari kegiatan pendampingan masyarakat ini diharapkan dapat memberikan pembelajaran bagi masyarakat dalam menentukan keputusan terkait dengan desain sesuai kebutuhan pengguna dalam hal ini tentunya masyarakat sekitar Masjid Al-Barkah.
