Abstract

Penelitian ini bertujuan mengembangkan dan menghasilkan alat peraga energi terbarukan berbasis solar cell pada pembelajaran IPA yang valid. Metode yang digunakan dalam penelitian ini adalah research and development (R&D) dengan model ADDIE. Namun, penelitian ini dibatasai hingga tahap development untuk menentukan validitas isi dari alat peraga yang dikembangkan. Subjek penelitian ini adalah siswa kelas IX dan guru IPA SMPN 4 Bengkulu Tengah. Teknik pengumpulan data berupa angket siswa, angket validasi ahli dan panduan wawancara guru. Teknik analisa data pada penelitian ini menggunakan teknik persentase dan rumus Aiken’s V untuk mengukur validitas alat peraga yang dikembangkan. Hasil penelitian menunjukkan bahwa alat peraga yang dikembangkan valid (layak) dengan nilai rata-rata indeks Aiken sebesar 0,98 yang telah melampaui standar batas minimal Aiken’ V untuk penelitian ini yaitu 0,92.

Abstract

The aim of this research was to determine the growth rate of jelawat fish seeds with a combination of commercial feed (PF 1000) and additional feed for earthworms (L. rubellus), to determine the best dose of artificial feed (PF 1000) and additional feed. food for earthworms (L. rubellus). for the growth of jelawat fish (L. hoevenii). This research used a Completely Randomized Design (CRD) with 4 treatments, namely doses P1 (100% pellets), P2 (25% pellets + 75% earthworms), P3 (50% pellets + 50% L. rubellus), and P4 (75% pellets + 25% L. rubellus) carried out for 28 days. The results of the research showed that the addition of earthworms had a significant effect on the increase in weight, length and width of jelawat fish seeds. The best growth was obtained in the treatment P2 pellets 25% + L. rubellus 75%, (1) The body weight of the jelawat fish during the study reached (11.22 g), (2) the body length of the jelawat fish was (38.8 mm), and (3) Body width of jelawat fish (5.71 mm). Based on the research that has been carried out, it can be concluded that the addition of (L. rubellus) has a real influence on the growth of L. heovenii and the highest specific growth is P2 (25% pellets + 75% L. rubellus) with a Specific Growth Rate (SGR) value of 40.07 %, Survival Rate (SR) 100%, Feed Intake (IF) 56,1g and Feed Conversion Ratio (FCR) 1.73 g.

Abstract

The aim of this study was to test the ethanol extract of Hongje fruit (Etlingera hemisphaerica) in regulating High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) levels in mice (Mus musculus). HDL and LDL levels were measured using four treatment groups (one control, two doses of  EEBE, and one dose of simvastatin), with each group with five M. musculus replicates whose pathological conditions were induced by a high-fat diet for 10 days. The extract given consisted of two doses of EEBE, namely (0.26 and 0.39) mg/dl Body Weight (BW) and a comparison dose (simvastatin 0.52 mg/dL BW). Data collection was carried out over a period of 13 days before and after EEBE grant. Based on the BNT test, the average HDL treatment level in the treatment group increased at the EEBE dose (0.39mg/g BW), namely before treatment the HDL level was 39.3 mg/dL and after treatment the HDL level was 41.8mg/dL by 6. 20%. Meanwhile, LDL in the treatment group experienced a decrease at the EEBE dose (0.39 mg/g BW), namely before treatment it was 145.2 mg/dL and after treatment it became 140.8 mg/dL by -3.30%.
