Abstract

Phenotype determination of sex in young canaries is very low in accuracy. This study aimed to develop a genotypic sexing method in canaries. This study used 12 canaries consisting of 3 mature males, 3 mature females and 6 one-month-old canaries. Phenotypic sexing by cloacal observation was done on all birds, continued by genotypic sexing to identification CHD1 gene using polymerase chain reaction (PCR). The PCR used blood samples for mature canaries, and feather for mature and one-month-old canaries. The results of phenotypic observations showed that all mature male canaries had prominent and pointed cloaca forms, all mature females had flat and wide, whereas all one-month-old birds had a flat cloaca. The result of PCR showed a single band (500 bp) for mature male and double bands (500 bp and 300 bp) for mature female canaries. The PCR results of one-month-old canaries showed that there were one male and five females. Based on this study, it was concluded that genotypic sexing using the PCR method is effective in the sex determination of canaries.Keywords: canary, CHD1, genotype, PCR, sexing ABSTRAKPenentuan jenis kelamin burung kenari muda secara fenotip akurasinya sangat rendah.

Abstract

Moderate Physical Exercise Increases Serum Vascular Endothelial Growth Factor and Stromal Cell-Derived Factor-1 Level Physical exercise affects many systems in the body that play a role in maintaining physical fitness and slowing down the aging process. This study aimed to identity VEGF and SDF-1 as the mechanism of exercise-related anti-aging therapy. This study was a randomized pretest-posttest control group design study, using 24 Wistar rats (Rattus norvegicus), male, 2.5-3 months old, weighing 180-200 g, and healthy. Rats were divided into two groups (n = 12). The control group was a sedentary lifestyle-treated group (P0) and the treatment group was subjected to moderate physical exercise for 4 weeks (P1). Both VEGF and SDF-1 levels were examined using the ELISA method. The results showed that moderate physical exercise increased VEGF (43.88 ± 6.24 to 69.80 ± 10.04 pg mL-1; p< 0.001) and SDF-1 (1.82±0.17 to 3.81±0.39 ng mL-1; p< 0.001) levels significantly. This study, therefore, suggested the possibility of VEGF and SDF-1 as a mediator of moderate physical exercise-induced anti-aging effect. Pelatihan fisik mempengaruhi berbagai sistem dalam tubuh yang berperan mempertahankan kebugaran fisik dan memperlambat proses penuaan. Penelitian menunjukkan bahwa kadar vascular endothelial growth factor (VEGF) dan stromal cell-derived factor-1 (SDF-1) menurun seiring dengan penuaan. Penelitian ini bertujuan membuktikan bahwa pelatihan fisik sedang meningkatkan kadar VEGF dan SDF-1 sebagai salah satu mekanisme penghambat proses penuaan. Penelitian ini menggunakan randomized pre-post test control group design dengan menggunakan 24 ekor tikus wistar (Rattus norvegicus) jantan sehat dengan umur 2,5 - 3 bulan, berat badan 180 -200 g yang dibagi dalam dua kelompok (n= 12 ekor). Kelompok kontrol tidak diberikan perlakuan atau sedentary lifestyle (P0) dan kelompok perlakuan diberi pelatihan fisik sedang selama 4 minggu (P1).  Kadar VEGF dan SDF-1 diperiksa menggunakan ELISA. Hasil penelitian menunjukkan bahwa pelatihan fisik sedang meningkatkan kadar VEGF (43,88±6,24 menjadi 69,80 ± 10,04 pg mL-1; p<0,001) dan SDF-1 (1,82 ± 0,17 to 3,81±0,39 ng mL-1; p< 0,001). Hasil penelitian ini menunjukkan kemungkinan VEGF dan SDF-1 sebagai mediator efek yang memperlambat penuaan. Namun, perlu dilakukan penelitian lebih lanjut untuk mengidentifikasi korelasi antara peningkatan kadar VEGF dan SDF-1 dengan fenotip penuaan.

Abstract

The revision of Ampelocissus was performed by observing the anatomical character of Ampelocissus leaves. The leaves were collected from 33 collection numbers of Herbarium Bogoriense (BO) and four collection numbers from Sumatra exploration. The purpose of this study is to update the information of diversity and to support species concept delimitation of Ampelocissus based on the anatomical study, especially on the sterile plant. Anatomical characters were observed on nine species and one variety of Sumatran Ampelocissus. Ampelocissus species is varied by the anatomical characters, i.e.: shape of the anticlinal wall of abaxial and adaxial epidermal cell, number of palisade layers, upper epidermal cell thickness, leaf thickness, presence of papillae on stomata neighboring cell, type, and shape of calcium oxalate crystals, also stomata position. The cluster analysis of Ampelocissus in Sumatra based on 16 anatomical characters showed the coefficient similarity in the range of 0.48 - 0.81. The research showed that the leaf anatomical characters can be used as additional characters to distinguish the species of Ampelocissus.

Abstract

Hematology Profile of Sprague-Dawley Male Rats (Rattus norvegicus) Aged 7 and 10 WeeksCurrently, the normal hematology profile has not been yet available for outbred rats in Indonesia. Most of the researchers use the data of hematology profile from references outside Indonesia in which the breeding environment is different. This study aimed to obtain a hematology profile of Sprague-Dawley male rats aged 7 and 10 weeks. The animals were obtained from the Laboratory of Animal Experiment, NADFC. Blood was drawn from the retro-orbital sinus and then analyzed to obtain the hematology profile including erythrocytes, hemoglobin, hematocrit, MCV, MCH, MCHC, leukocytes. Statistically significant differences for erythrocytes, hemoglobin, MCV, MCHC, thrombocyte, and leukocytes parameters were observed between rats aged 7 and 10 weeks. However, there were no statistically significant differences observed on MCH, thrombocyte, and body weight parameters. Data presented here would be useful as a reference for hematology research as well as in evaluating alterations in blood parameters.Keywords: erythrocyte, hematology, leukocyte, Sprague-Dawley, thrombocyteABSTRAKSaat ini belum banyak tersedia informasi profil hematologi untuk hewan coba tikus yang dikembangbiakkan di Indonesia.

Abstract

Antifungal Activity of Wood Vinegar derived from Oil Palm Empty Bunches against Colletotrichum sp. (WA2) Colletotrichum sp. is a fungus that causes anthracnose in cayenne pepper (Capsicum frutescens L.).  An alternative natural control for this fungus is using wood vinegar. The aim of this study was to evaluate antifungal properties of wood vinegar from oil palm empty bunches (Elaeis guineensis Jacq.) against Colletotrichum sp. The antifungal test was carried out using the solid dilution method by poisoning food in potato dextrose agar (PDA) media. Colletotrichum sp. used was isolated from red chili which had anthracnose symptoms. This experimental research method used a completely randomized design (CRD) with 9 treatments, namely, negative control (non-liquid smoke), positive control (Dithane M45 at 0.20%), liquid smoke concentration of 0.40; 0.42; 0.44; 0.46; 0.48; 0.50; and 0.52%. Anova test results showed wood vinegar from empty fruit bunches of E. guineensis at concentrations of 0.40; 0.42; 0.44; 0.46 and 0.48% differed significantly from negative control, positive control, and concentrations of 0.50 and 0.52%. The concentration of 0.42% was the minimum inhibitory concentration with an average value of 87.98% inhibition and a very strong activity level. In conclusion, the wood vinegar from E. guineensis can be used to control Colletotrichum sp fungus at an effective concentration of 0.42%. Colletotrichum sp. merupakan jamur penyebab penyakit antraknosa pada tanaman cabai rawit (Capsicum frutescens L.). Salah satu alternatif pengendalian secara alami terhadap jamur tersebut adalah dengan menggunakan asap cair. Penelitian ini bertujuan untuk mengevaluasi sifat antijamur asap cair dari tandan kosong Elaeis guineensis Jacq (kelapa sawit) terhadap Colletotrichum sp. Uji antijamur dilakukan dengan metode dilusi padat melalui cara poisoning food dalam media potato dextrose agar (PDA). Isolat jamur Colletotrichum sp. yang digunakan merupakan hasil isolasi dari tanaman cabe merah yang bergejala antraknosa. Metode penelitian ini mengunakan rancangan acak lengkap (RAL) dengan 9 perlakuan, yaitu kontrol negatif (tanpa asap cair), kontrol positif (Dithane M45 sebesar 0,20%), konsentrasi asap cair sebesar 0,40; 0,42; 0,44; 0,46; 0,48; 0,50; dan 0,52%. Hasil uji Anova menunjukkan asap cair dari tandan kosong E. guineensis pada konsentrasi 0,40; 0,42; 0,44; 0,46; dan 0,48% berbeda secara signifikan dengan kontrol negatif, kontrol positif dan konsentrasi 0,50 dan 0,52%. Konsentrasi 0,42% merupakan konsentrasi hambat minimum dengan nilai rata-rata penghambatan sebesar 87,98% dan tingkat aktivitas sangat kuat. Dengan demikian dapat disimpulkan bahwa asap cair dari tandan kosong E. guineensis dapat digunakan untuk mengendalikan jamur Colletotrichum sp. pada konsentrasi efektif 0,42%.

Abstract

Generally, the standard procedure for karyotype analysis of shallot is sorted by chromosome sizes. Therefore, the identification of homologous chromosomes is difficult without using a specific probe. Nucleolus Organizing Regions (NORs) can be used as a probe for precise identification of homologous chromosomes. However, the use of NORs for plant karyotyping in Indonesia is poorly investigated. In this study, shallot chromosomes were prepared using modified Carnoy’s solution II, fixed in Carnoy’s solution, and stained by using aceto-carmine and AgNO3 for detecting NORs. Chromosome images were analyzed by CHIAS IV. One locus NOR bearing chromosome pair was detected at metaphase and interphase, and it was located at short arms of subtelomeric chromosome number 6. NORs can be used as a probe for precise identification of homologous chromosomes in shallot. Therefore, this technique has the potential to be applied on species closely related to shallot and on other plant species.Keywords: AgNO3, chromosome condensation, NORs, shallot chromosome, shallot karyotype ABSTRAKProsedur kariotipe untuk bawang merah umumnya masih disusun berdasarkan ukuran kromosom, sehingga diperlukan suatu penanda yang dapat mengidentifikasi kromosom homolog secara presisi. Identifikasi kromosom homolog secara presisi menggunakan suatu penanda, khususnya deteksi Nucleolus Organizing Regions (NORs), yang di Indonesia masih jarang dilakukan. Penelitian ini bertujuan untuk membuat kariotipe dan mengidentifikasi kromosom homolog bawang merah melalui deteksi NORs menggunakan metode pewarnaan AgNO3. Proses fiksasi akar dilakukan dengan menggunakan modifikasi larutan Carnoy II, lalu difiksasi dengan larutan Carnoy, dan kromosom diwarnai dengan aceto-carmine dan larutan AgNO3 untuk mendeteksi NORs. Selanjutnya, citra kromosom dianalisis menggunakan CHIAS IV. Hasil penelitian menunjukkan bahwa terdapat sepasang NORs yang terdeteksi pada fase metafase dan interfase yang  terletak pada bagian lengan pendek di kromosom subtelosentrik nomor 6. Hasil dari penelitian ini dapat dijadikan sebagai dasar di bidang sitogenetika bawang merah untuk mengidentifikasi kromosom homolog secara presisi menggunakan penanda NOR. Oleh karenanya, teknik ini dapat diaplikasikan pada spesies yang berdekatan dengan bawang merah dan komoditas tanaman lainnya.Kata Kunci: AgNO3, kariotipe bawang, kondensasi kromosom, kromosom bawang, NORs

Abstract

Effect of Fermentation on Antioxidant Activities and Betacyanin Content of Functional Beverages from Dragon Fruit and BeetrootKombucha is a traditional beverage prepared by fermenting polyphenol-rich tea using a consortium of bacteria and yeast (SCOBY). Dragon fruit and beetroot contain a significantly high amount of polyphenols and betacyanin as antioxidants which are beneficial in reducing the risk of cardiovascular disease, cancer, and the body's natural degeneration related to the early-aging process. This study aims to determine changes in antioxidant activity and levels of betacyanin from fermented dragon fruit and beetroot as functional drinks during different fermentation times. The results showed that there was a correlation between fermentation time and antioxidant activity in its ability to counteract free radicals, ferric reducing antioxidant power (FRAP), and the levels of betacyanin produced. Longer fermentation time caused an increase in free radical inhibition and reduction of iron ions but reduced the levels of betacyanin. The optimum value of free radical inhibitory activity (DPPH) was obtained in the 12-day fermented dragon fruit drink with an inhibitory value of 80.76%, ability to reduce iron ions by 197.94 µg ascorbic acid mL-1, and betacyanin level of 0.055 mg L-1Keywords: antioxidants, dragon fruit, betacyanin, beetroot, functional beverages ABSTRAKKombucha merupakan minuman tradisional hasil olahan fermentasi teh yang kaya polifenol dengan konsorsium bakteri dan yeast (SCOBY). Buah naga dan umbi bit memiliki polifenol dan senyawa betasianin yang cukup tinggi sebagai antioksidan yang bermanfaat dalam menurunkan risiko penyakit kardiovaskular, penyakit kanker dan degenerasi alami tubuh terkait proses penuaan dini. Penelitian ini bertujuan untuk mengetahui perubahan aktivitas antioksidan dan kadar betasianin dari fermentasi buah naga maupun umbi bit sebagai minuman fungsional selama waktu fermentasi yang berbeda. Hasil penelitian menunjukkan bahwa adanya korelasi antara waktu fermentasi terhadap aktivitas antioksidan dalam kemampuannya menangkal radikal bebas, kemampuan mereduksi ion besi (FRAP), dan kadar betasianin yang dihasilkan. Semakin lama waktu fermentasi menyebabkan peningkatan penghambatan radikal bebas dan reduksi ion besi, namun menurunkan kadar betasianin. Nilai aktivitas penghambatan radikal bebas (DPPH) optimum diperoleh dari minuman fermentasi buah naga selama waktu fermentasi 12 hari dengan nilai penghambatan sebesar 80,76%, kemampuannya dalam mereduksi ion besi sebesar 197,94 µg asam askorbat mL–1, dan kadar betasianin sebesar 0,055 mg L–1
