Abstract

Salah satu keterampilan yang dibutuhkan di abad 21 yaitu kreativitas (creativity). Namun di lapangan masih ditemukan permasalahan belum maksimalnya kreativitas siswa, salah satu faktornya adalah kurangnya bahan ajar yang mendukung. Bahan ajar yang tersedia disekolah sangat terbatas. Padahal dalam pembelajaran apresiasi seni rupa berpotensi mengembangkan kreativitas siswa. Pembelajaran seni memiliki peran membentuk kreativitas peserta didik. Sehingga solusi yang diambil melalui penelitian ini adalah mengembangkan buku ajar berbasis inkuiri. Tujuan Penelitian adalah mengembangkan buku ajar pembelajaran apresiasi seni rupa berbasis inkuiri yang valid untuk meningkatkan kreativitas siswa fase F di SMA Negeri 1 Palibelo Bima yang disesuaikan dengan kurikulum merdeka. Metode penelitian adalah metode pengembangan yang mengacu pada model ADDIE. Hasil penelitian menunjukkan bahwa penilaian ahli I, II, III untuk aspek cakupan materi berturut-turut dengan persentase 96%, 94% , 94% berkategori sangat baik. Penilaian ahli I, II, II untuk aspek kebahasaan dengan persentase 90%, 90%, 95% berkategori sangat baik. Penilaian ahli I, II, III Aspek Kontruk/tampilan dengan persentase 83% berkategori sangat baik dan 80%,81% berkategori baik. Jadi Buku ajar yang dikembangkan valid digunakan untuk meningkatkan kreativitas siswa.

Abstract

BACKGROUND: Malnutrition is a global health concern that results in changes in nutritional status, as indicated by alterations in phenotypic markers, hematological and biochemical parameters, and increased susceptibility to infection, as shown by decreased interleukin (IL)-2 levels. Andrographolide, the active component of Andrographis paniculata, stimulates the immune system and exhibits antibacterial and antiviral activity. Therefore, A. paniculata may serve as a potential adjuvant therapy for malnutrition. This study was conducted to analyze the effect of A. paniculata as an immunomodulator against malnutrition with characteristics of environmental enteric dysfunction (EED) and a low-protein diet by examining phenotypic markers, hematological, biochemical, and IL-2 levels.METHODS: Forty-five male Wistar rats were divided into seven groups. They were fed either a standard or a low-protein diet before receiving oral administration of various concentrations of A. paniculata leaf extract (APLE). APLE was administered 21 days after the initial low-protein diet. Hematological, biochemical, and phenotypic markers were assessed to determine the nutritional status of the rats. The protective effects of APLE were evaluated by measuring IL-2 levels using enzyme-linked immunosorbent assay (ELISA).RESULTS: Malnourished rats exhibited slow body growth, physical and behavioral changes, reduced leukocyte count, total protein, albumin, cholesterol, and villi length. Malnourished rats treated with APLE showed a more effective and significant increase in IL-2 levels, with higher concentrations of APLE resulting in higher IL-2 levels.CONCLUSION: APLE, in a concentration-dependent manner, can increase IL-2 levels, suggesting that APLE may have potential protective effects in a rat model of malnutrition.KEYWORDS: Andrographis paniculata, environmental enteric dysfunction, interleukin (IL)-2, low protein, malnutrition

Abstract

Spirogyra peipingensis is a species of green algae known to have a high carbohydrate content, making it a promising alternative raw material for biosugar production. This study aimed to determine the effects of inoculum size and pretreatment duration on biosugar yield. The research was conducted in three stages: pretreatment, hydrolysis, and fermentation. Pretreatment was carried out to release polysaccharides, hydrolysis was performed to convert cellulose and hemicellulose into simpler forms, and fermentation was conducted to transform disaccharides into monosaccharides. Monosaccharide measurement was performed using an ATC refractometer with a refractive index method to estimate the total sugar content. The results showed that the combination of a 7.5% inoculum size with a fermentation duration of 24 hours produced the most optimal monosaccharide yield, amounting to 0.28 g/g substrate. These findings emphasize that the regulation of inoculum and pretreatment parameters plays a crucial role in enhancing the efficiency of algal biomass conversion into biosugar. Overall, this study contributes to the development of bioconversion technologies based on local biological resources and highlights the potential of Spirogyra peipingensis as an environmentally friendly raw material candidate for future biosugar industries.
