Abstract

Stevia Rebaudiana Bertoni  adalah sejenis Tanaman perdu yang belum banyak dikenal oleh masyarakat. Didalam Industri, banyak digunakan sebagai bahan pemanis untuk produk makanan dan minuman berkalori rendah atau sebagai pengganti gula bagi penderita diabetes.Proses pengambilan bahan pemanis dari daun Stevia Rebaudiana dilakukan dengan cara ekstraksi bubuk daun didalam pelarut ( metanol,etanol ,spiritus  , aquadest ) yang dilanjutkan dengan pencucian  menggunakan Khloroform.Kemudian dicuci kembali dengan n- Butanol dan diuapkan dengan menggunakan metanol panas kemudian disaring.Dari hasil penelitian didapatkan kondisi operasi yang relatif baik untuk mengekstraksi daun stevia ,yaitu pada delapan kali sirkulasi dengan pelarut metanol teknis.Kristal halus yang terambil dari 20 gram serbuk stevia dengan volume pelarut 200 ml berwarna coklat, berat 0.2985 gram dengan indeks bias 1.3950 Kata Kunci  : Stevia Rebaudiana Bertoni, Diabetes, Ekstraksi

Abstract

The preparation of radiopharmaceuticals may necessitate close contact with the radioactive source. In this case, high-energy beta-emitting nuclides can cause a high exposure. There are two methods of measuring the dose in the extremities, including using a bracelet and a ring dosimeter. In this study, the response of Hp(0.07) dose in TLD-700 and TLD-900-based ring dosimeters to Sr-90 beta radiation will be compared for parameters of distance, time, and angle of irradiation. The dosimeters were irradiated using Sr-90 at a distance of 5, 7, and 10 cm from the source surface and all of them were subsequently read with TLD Reader. The same type of dosimeters were exposed to Sr-90 for 1 day, 2 days, and 3 days at a distance of 7 cm and read. At a distance of 7 cm, the other dosimeters were irradiated at angles of 30°, 60°, -30°, and -60°, and then read. The study shows that the relationship between the distance of irradiation to Hp(0.07) dose is polynomial with a correlation factor of 1, both for TLD-700 and TLD-900-based ring dosimeters. The dose response at the variation of irradiation time showed linear behavior with correlation coefficients of 0.9942 and 0.9999 for TLD-700 and TLD-900, respectively. The decrease in Hp(0.07) response in TLD-700 reached 14-31 % for the irradiation angle of ±30o and 23-27 % in TLD-900 for the same angle. Meanwhile, the decrease in Hp(0.07) response at the angle of irradiation ±60o reached 48 % for TLD-700 and 66-67 % for TLD-900.

Abstract

This study aimed to determine the effect of combining phytogenic Curcuma aeruginosa Roxb powder with C. xanthorizza standardized extract or with Anredera cordifolia leaf powder in an antibiotic-free diet on the egg production, red and white blood cell profile, fecal endoparasite, serum biochemistry, and intestinal and liver histopathology of Japanese quails. Four hundred eight-month-old Japanese quails were raised in 5-tier cages, randomly allocated into four treatments, namely: T0 (standard diet), T1 (standard diet plus 1% C. aeruginosa Roxb rhizome powder), T2 (standard diet plus 1% C. aeruginosa Roxb rhizome powder and C. aeruginosa extract (equal to 200 ppm standardized curcumin), and T3 (standard diet plus 1% C. aeruginosa Roxb powder and 1% A. cordifolia leaf powder). The data were analyzed using variance analysis (ANOVA). Duncan’s test was carried out at a 5% significant level when a significant effect was found. The results showed that weekly egg production was not affected by phytogenic addition, but egg production significantly increased on the last day of treatment (p<0.05). Combining 1% C. aeruginosa Roxb and 1% A. cordifolia significantly increased (p<0.05) erythrocytes, hemoglobin, hematocrit, leukocytes, lymphocytes, serum glucose, uric acid, creatinine, and AST. However, their values remained within the normal range of Japanese quails. No endoparasites were found in the fecal samples. The addition of phytogenic did not affect the height of intestinal villi and crypt depth (p>0.05). Interestingly, intestinal inflammation levels were reduced significantly in T1 and T2 compared to the control, while T3 was the same as the control (p<0.05). An elevated liver score was found (1 score higher) in T2 (p<0.05). This study suggests that phytogenic additives can help reduce normal intestinal inflammation (due to harsh intestinal environment) and improve the performance of laying Japanese quail, especially in the absence of endoparasites or infection.

Abstract

Quail farming is vital for smallholder farmers in Central Java, Indonesia; however, productivity often declines due to poor biosecurity, inadequate water quality, and parasitic infections. This study aims to examine biosecurity practices, water quality, and endoparasite loads in ten quail farms (L1-L10) located in Semarang City and nearby regencies. Data were collected through observations, interviews, water sampling, and analysis of quail droppings. Biosecurity scores (maximum 18) were categorized into three groups: Group-1 (scores 13-18), Group-2 (scores 7-12), and Group-3 (scores 1-6). Water quality was assessed based on pH, E. coli, and coliform counts using triplicate samples from each site. The biosecurity score showed that three farms are in Group-1 (L1, L7, L9), five are in Group-2, and two are in Group-3 (L8, L10). The water pH ranged from 4.8 to 8.0; the highest E. coli count was 19.33 CFU/mL (L9), and the highest Coliform count was 89.67 CFU/mL (L5). L1 had the highest parasite load, with Coccidia, Strongyloides, and Ascaridia sp. at 1000 oocysts/g (OPG), 100 OPG, and 33.33 OPG, respectively. Meanwhile, L7 showed no endoparasites or water contamination. Egg production ranged from 64.29% to 90.00%. Although no significant differences in endoparasite prevalence were found among biosecurity groups or water quality (p>0.05), Coliform levels differed significantly (p<0.05), with the highest levels in conventional well-water. This study revealed that only about one-third of smallholder quail farms in Semarang and its surrounding regencies adhere to proper biosecurity measures. It was also the first to document quail endoparasite burdens as well as E. coli and coliform contamination in drinking water.
