Abstract

The purpose of this study is to determine the potential extract of areca nut (Areca catechu L.) seeds, skin and the combination of the two extracts in killing the Aedes aegypti larvae. This study used a Completely Randomized Design in the seed extract test with a concentration of 16000, 17000, 18000, 19000 and 20000 ppm and skin extract with concentrations of 7000, 8000, 9000, 10000 and 11000 ppm. The factorial design was used in the combined extract of 0:100; 25:75; 50:50; 75:25 and 100:0. Each treatment used 4 replications. Data were analyzed by ANOVA and then continued by Tukey, LSD and Duncan tests. The last, data were analyzed by probit analysis to determine LC50 and LC90. The result indicates that areca nut seed and skin contain flavonoid, alkaloid, palmitic acid, phenols, terpenoids and steroids which are toxic. The killing power of seed extract was 64-97% (24hours) and 100% in all treatments (48hours). Skin extract was 52-88% (24hours) and 58-93% (48hours), while the combination extract was 55 -93% (24hours) and 95-100% (48hours). Concentration of 19000 ppm of seed extract with 95% mortality at 24 hours was effective when compared to the WHO standard (2005), while the skin extract had a lower LC value than the other two extracts.

Abstract

UV filters are necessary since UV rays are harmful to human skin. UV filter compounds in commercial sunscreen products can cause adverse effects. Thus, natural UV filters containing flavonoids, e.g. Frangipani (Plumeria alba Linn.) leaves, are needed. This research examined the use of flavonoids from P. alba leaf as a UV filter with in vitro and in vivo. Maceration was performed with 70% ethyl alco-hol and liquid-liquid extraction for flavonoid purification. Parameters tested were total flavonoid compounds, SPF value, and clinical symptoms of the melanogenesis inhibition scoring. The purification result was 43.6%. The flavonoid concentration in pure extract (64.4 mg QE /g) was higher than crude extract (57.6 mg QE/g). The highest SPF value (33.88) was observed in pure extract at 1400 mg/mL, while the same concentration of crude extract resulted in a lower SPF value (33.06). Pearson correlation analysis (0.536) indicated a di-rectly proportional relationship between SPF value and extract concentration. In vivo analysis was performed by scoring between 0-4 following the severity of erythema. After 21 days of sunlight exposure, the worst erythema was found in the negative control group (score 1.292). The best result was found in the group treated with pure extract 1400 mg/ml (score 0.542).

Abstract

Kesambi is a plant widely used by people of Timor Island. Flavonoid content of Kesambi is potential to be used as immunomodulators. This study aimed  to study the effect of Kesambi bark extract on lymphocyte count and spleen index of male mice as an indicator of their immune responses. Research included identification of phytochemical compounds macerated from Kesambi bark, lymphocytes count and spleen index calculation. Mice injected with sheep erythrocytes were treated orally with three doses of Kesambi extract (0.113 mg/g BW, 0.491 mg/g BW, and 0.712 mg/g BW) for 10 days. Lymphocyte count using blood smear method was carried out on day 0, 5 and 10, while lymphocyte count using hematology analyzer and spleen index measurement were performed after mice sacrificed. Kesambi bark contains alkaloids, flavonoids, tannins, and steroids. Treatment with Kesambi bark extract reduced mice lymphocyte count. Administration of 0.491 mg/gr BW dose reduced the mice lymphocytes count close to the number of lymphocytes in the negative control group. The spleen index of mice had no correlation with changes in the number of lymphocytes. This preliminary study shows a potential use of Kesambi bark extract as a natural immunosuppressant.

Abstract

Growth Promoter Antibiotics are used to prevent disease and promote growth and production in poultry. Repeated admnistration of feed can have a microorganic resistance effect, accumulation of antibiotic residues in animal and environmental products and imbalance of normal microflora in the intestine. The antibacterial and carbohydrate content of some natural ingredients can be potential as a replacement candidate for AGP. This study aims to determine the role of a combination of wild ginger, honey, and probiotics (Bacillus subtilis and Lactobacillus acidophilus) as AGP candiate in Vitro. The antibacterial activity of the combination of wild ginger and honey against pathogens (E. coli) and their use against probiotics was tested by disk diffusion method, while the calculation of optical density values to determine the minimum inhibitory concentration and minimum bactericidal concentration was carried out on E. coli. The ability of inhibition of probiotics against pathogens is also done by the disk diffusion method. The disk diffusion test results showed the best combination was extract of 25% wild ginger aquades + 100% Lombok honey with inhibition zone diameter (8,53 ±, 03). Optical density values indicate this combination is able to inhibit and kill E. coli (DO 0,00 ±, 002) and support B. subtilis (DO 0,18 ±, 002) and L. acidophilus (DO 0.25 ±, 005) significantly better than positive control. MIC value of wild ginger aquades extract and honey combination against E. coli is wild ginger aquades extract 3.13% + Lombok honey 25%, while MBC value is wild ginger aquades extract 6,25% + Lombok honey 25%. The combination of B. subtilis and L. acidophilus showed the largest inhibitory zone diameter against E. coli (7,30 ±, 02 mm) compared to individual colonies. The combination of wild ginger and honey, in addition to inhibiting also able to kill pathogens and support the growth of probiotics, so this formula can be used as one of the replacement candidates for AGP.

Kolagen yang dihasilkan memenuhi kriteria Badan Standardisasi Nasional (BSN) (2014) pada jumlah mikrobia dan total coliform tetapi belum memenuhi pada kadar protein, pH, dan kadar air. Pada uji preklinis digunakan kolagen hasil ekstraksi dengan penambahan 20% ekstrak kulit buah pepaya yang memenuhi kriteria BSN dengan kadar protein terbanyak. Serum kolagen dibuat menjadi tiga konsentrasi, yaitu 5, 10, dan 20 mg/mL. Hasil pengujian preklinis menunjukkan bahwa kelompok perlakuan kolagen 20 mg/mL memiliki presentase penutupan luka kulit mencit terbaik sebesar 84,61%, dari hasil pengujian statistik menunjukkan tidak ada perbedaan signifikan dengan kelompok perlakuan kontrol positif.AbstractThe papaya peel, which is a part of papaya not typically consumed, contains the papain enzyme that can be used as a substitute for pure papain to extract the collagen. Squid tentacles are one of the mainsources of marine collagen. The extraction of collagen from squid tentacles was conducted using a maceration method with CH3CHOOH solvent, and the papaya peel extract was added at concentrations of 5, 10, 15, and 20%, respectively. The extraction process showed that the addition of 15% papaya peel extract provided the best result of 19.2% (bb). The collagen produced in this experiment met the BSN criteria for total microbes and total coliforms. However, it did not yet comply with the BSN criteria for protein content, pH, and water levels. The preclinical testing utilized the extracted collagen and the papaya peel extract with a 20% concentration, which met the BSN standards with the highest protein level. The serum collagen was divided into three concentrations: 5 mg/ml, 10 mg/ml, and 20 mg/ml. Preclinical studies showed that the treatment group receiving 20 mg/mL collagen exhibited the highest percentage of skin wound healing at 84.61%, and the statistical test found no significant difference compared to the positive control treatment group.

Abstract

Javan langur (Trachypithecus auratus) is one of the endemic primate species of Indonesia. Its populations were exposed to extinction risk caused by human activities. Thus, conservation efforts such as ex-situ conservation were needed to preserve this species. One of the javan langur ex-situ conservation in Yogyakarta is the Gembira Loka Zoo. In captivity, animals must be guaranteed to be free from hunger and stay nourished. One aspect to support this welfare is food supply. Therefore, this study aimed to identify the food composition and analyze the correlation between food preference and feeding duration of each food item group. We used scan animal sampling method with five minutes intervals to observe the behavior of seven individuals of captive javan langurs. The result showed that there are three groups of food (fruit, vegetable, and leaf) provided daily to javan langurs in Gembira Loka Zoo. All the individuals spent most their time to consumed food from vegetable group, except for infant female who had the highest duration in the leaf group. In addition, based on which food they consumed first every feeding time (preference food), javan langurs preferred vegetable over fruit and leaf. Based on the Spearman correlation test, there are positive correlations of duration and preference of feeding except for leaf groups. This result was different from the natural food composition of javan langurs which mostly consisted of leaves. This study might help the zoo to consider the food items provided for the animals to increase animal welfare.

Abstract

The mistletoe (Scurrula ferruginea) is a parasitic plant obtaining nutrients and water from host plants at Nglinggo tea plantation, Kulon Progo, Yogyakarta. Despite the numerous benefits of Scurrula ferruginea leaf, substantiation regarding its pharmacological activity is still lacking. Therefore, this research aimed to identify Scurrula ferruginea species and obtain secondary metabolites with antibacterial activity. The experiment was carried out by extracting Scurrula ferruginea leaf using maceration methods with 96% ethanol, followed by qualitatively and quantitatively phytochemical screening, inhibitory zone test, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) test. Several compounds, such as flavonoids, tannins, phenols, saponins, alkaloids, terpenoids, and steroids, were identified in the mistletoe extract. The results showed total flavonoid, phenolic, and tannin levels were 7.41 ± 0.38 mg QE/mg, 1672 ± 50.99 mg GAE/g, and 1.43 ± 0.15 mg TAE/g, respectively. Scurrula ferruginea leaf ethanolic extract showed the potential to form an inhibition zone against S. aureus in the moderate category at 525 mg/mL, but no significant activity was observed against E. coli. The MIC results of Scurrula ferruginea leaf ethanolic extract against S. aureus were 0.6%, and the MBC was at 2.4%. Furthermore, the MIC value against E. coli was 14%, and the MBC value was 28%. Based on these results, it could be concluded that Scurrula ferruginea leaf ethanolic extract showed high effectiveness in inhibiting and killing S. aureus bacteria compared to E. coli, with MIC and MBC values of 0.6% and 2.4%, respectively
