Abstract

Spices are known for its health beneficial effect beside its function as flavouring and condiment. This study aimed to screen immunostimulant activities of 12 underutilized species of Zingiberaceae grown in Indonesia. The compound associated with immunostimulant activity in the most active sample was identified by linking the chromatogram profile of hexane, chloroform, ethyl acetate, methanol, and water fractions of the selected spices to its activity using orthogonal projection to the least square (OPLS) analysis, followed by LC-MS characterization. The result showed that Alpinia malaccensis and Zingiber ottensii had the highest lymphocyte cell proliferation index (SI) at concentrations of 400 ppm. A. malaccensis was chosen for the next step. The results of OPLS analysis showed that the retention time interval which strongly correlated with the immunostimulant activity was 27.0 – 28.5 minutes, which were abundant in methanol fraction. The mass spectra analysis of methanol fraction using UHPLC-HRMS showed that the respective retention time was attributed to flavokawain B. This compound was reported to increase rat splenocyte proliferation in vivo.

Abstract

This study examines the religious guidance of converts at Pesantren Mualaf Indonesia Dompet Dhuafa through the frameworks of Max Heirich’s conversion theory and Glock and Stark’s religiosity theory. Heirich’s theory is applied to analyze the transformation of spiritual identity and commitment among converts within the pesantren environment. Meanwhile, Glock and Stark’s theory is used to assess the dimensions of belief, practice, experience, and affective religiosity of the converts. The findings indicate that the pesantren's comprehensive approach and intensive support significantly enhance the religiosity and spiritual integration of the converts. This research provides valuable insights into the effectiveness of religious guidance methods in strengthening the religious identity and commitment of new Muslims in the pesantren context.

Abstract

This study optimized chitin extraction into chitosan from mangrove crab shells using the Response Surface Methodology (RSM) approach. Three independent factors were used: NaOH concentration (A), deacetylation temperature (B), and deacetylation time (C) at five levels (-α, -1, 0, +1, α). The NaOH concentration ranged from 43.2% to 78.8%, the deacetylation temperature ranged from 83.2°C to 116.8°C, and the deacetylation time ranged from 0.4 hours to 3.6 hours. The dependent variables were yield (Y1), degree of deacetylation (Y2), intrinsic viscosity (Y3), and molecular weight (Y4). The results of chitin deacetylation to chitosan optimization using the Design Expert program with the RSM approach led to 42 optimization formulas. The formula with the highest desirability value of 0.927 was the extraction condition using a 50% NaOH concentration, 110°C deacetylation temperature, and 1 hour deacetylation time. Chitosan obtained under these extraction conditions yielded 33.61%, a deacetylation degree of 79.2%, an intrinsic viscosity of 34.96 ml/g, and a molecular weight of 9.25 kDa. The deacetylation of the chitosan produced met the quality standards from Protan Laboratory, as deacetylation was ≥70%.

Abstract

Pelatihan pengelolaan dan pengembangan website di Universitas Teuku Umar bertujuan untuk meningkatkan kompetensi para pengelola website di lingkungan fakultas dan unit kerja universitas. Dalam era digital ini, pengelolaan website yang efektif sangat penting untuk memastikan informasi yang disampaikan selalu up-to-date, menarik, dan mudah diakses oleh mahasiswa, dosen, serta masyarakat umum. Pelatihan ini melibatkan peserta dari berbagai fakultas dan unit kerja yang bertanggung jawab atas pengelolaan website, dengan tujuan untuk memastikan bahwa setiap bagian terkait memiliki keterampilan yang seragam dalam mengelola konten website. Materi pelatihan mencakup pengelolaan konten dan penggunaan sistem WordPress sebagai platform pengelolaan website yang fleksibel dan mudah digunakan. Pelatihan ini juga membahas pengelolaan warna dan konten sesuai dengan standar yang ditetapkan oleh masing-masing instansi. Hasil dari pelatihan menunjukkan bahwa peserta mampu mengatasi tantangan yang dihadapi dalam mengelola website, serta dapat langsung mempraktikkan pengetahuan yang diperoleh, seperti pengeditan konten dan pembaruan tampilan website. Keberhasilan pelatihan ini diharapkan dapat mendukung proses Re-Akreditasi dan peralihan status Universitas Teuku Umar menuju Badan Layanan Umum (BLU), serta memberikan kontribusi positif dalam meningkatkan kualitas pengelolaan website universitas di masa mendatang. Pelatihan ini diharapkan dapat dilanjutkan secara berkala untuk memperkuat kapasitas pengelola website dalam menghadapi perkembangan teknologi digital.
