Abstract

Being the world’s third largest producer of cocoa (Theobroma cacao), Indonesia provides abundant cocoa pod husk byproduct. Despite its high content of biological materials, its use as animal feed, however, has been limited due to its low nutritive values and significant content of antinutritive substances. Thus, this study was aimed to investigate the changes of selected amino acids glutamate, aspartate, valine, alanine, and proline, as well as the antinutritional compound theobromine in cocoa byproduct-rice bran mixed substrate following fermentation using Rhizopus oryzae. The fermented substrate obtained had its true protein content increased from 1.95% to 23.16%. After analyses using ultra-performance liquid chromatography quadrupole time of flight mass spectrometry, the following amino acids, namely: total and free glutamates, total and free valine, total proline, as well as free alanine underwent increase, while the others decreased. The concentration of the antinutritional factor theobromine was below the limit detectable by HPLC.Keywords: Rhizopus oryzae, Theobroma cacao, theobromine, fermentation, amino acidsABSTRAKSebagai penghasil kakao (Theobroma cacao) terbesar ketiga di dunia, Indonesia mempunyai hasil samping melimpah berupa kulit cangkang kakao. Meskipun kandungan bahan biologisnya tinggi, penggunaan produk samping ini sebagai pakan ternak masih terbatas karena nilai gizi yang rendah serta kandungan zat antinutrisi yang tinggi. Oleh karenanya, penelitian ini bertujuan mengetahui perubahan kandungan asam amino glutamat, aspartat, valin, alanin, dan prolin, serta senyawa antinutrisi teobromin dalam campuran hasil samping coklat-dedak padi pasca fermentasi menggunakan Rhizopus oryzae. Substrat hasil fermentasi mengalami peningkatan kandungan protein sejati dari 1,95% menjadi 23,16%. Hasil analisis menggunakan ultra-performance liquid chromatography quadrupole time of flight mass spectrometry, menunjukkan bahwa kandungan asam amino: glutamat total dan glutamat bebas, valin total dan valin bebas, prolin total, serta alanin bebas mengalami peningkatan, sementara asam amino selainnya mengalami penurunan. Kandungan antinutrisi teobromin berada di bawah ambang batas deteksi oleh HPLC.Kata kunci: Rhizopus oryzae, Theobroma cacao, teobromin, fermentasi, asam amino

Abstract

Cephalosporins are the most widely used class of β-lactam antibiotic in the world and clinically active against gram positive and gram negative bacteria. Cephalosporin C (CPC) is naturally produced by fungus Cephalosporiun acremonium. CPC has moderate antibacterial activity with minimum inhibitory concentration values of 25-100 µg/mL and 12-25 µg/mL for gram-positive and for gram-negative bacteria, respectively. CPC can be converted into 7-aminocephalosporonic acid (7-ACA) as intermediate compound for cephalosporin derivatives by two-steps or one-step enzymatic method. Two-step enzymatic method uses D-amino acid oxidase (DAAO) to produce glutaryl-7-amino cephalosporanic acid (GL 7-ACA) for the first step and GL-7-ACA acylase to produce 7-ACA for the second step. One-step enzymatic method uses CPC acylase to convert CPC into 7-ACA directly. Some microorganisms produce CPC acylase, such as Pseudomonas sp., Bacillus megaterium, Aeromonas sp., dan Arthrobacler. A natural CPC acylase has low activity and genetic engineering was used to increase its activity.Keywords: Cephalosporin, cephalosporin acylase, 7-ACA, genetic engineering, mutation ABSTRAKSefalosporin merupakan antibiotik golongan β-laktam yang paling banyak digunakan di dunia dan secara klinis aktif terhadap bakteri gram positif dan gram negatif. Sefalosporin C merupakan sefalosporin alami yang dihasilkan oleh kapang Cephalosporium acremonium. Sefalosporin C mempunyai aktivitas antibakteri moderat dengan nilai konsentrasi hambat minimum 25-100 µg/mL untuk bakteri gram positif dan 12-25 µg/mL untuk bakteri gram negatif. Sefalosporin C dapat diubah menjadi asam 7-aminosefalosporanat (7-ACA) sebagai senyawa antara untuk pembuatan turunan sefalosporin dengan metode enzimatik secara dua atau satu tahap. Produksi 7-ACA secara enzimatik dapat menggunakan metode dua tahap dan satu tahap enzimatik. Metode enzimatik secara dua tahap menggunakan enzim asam D-amino oksidase (DAAO) untuk menghasilkan asam glutaril-7-aminosefalosporinat (GL-7-ACA) pada tahap pertama dan menggunakan asam glutaril-7-aminosefalosporinat asilase untuk menghasilkan 7-ACA pada tahap kedua. Metode enzimatik secara satu tahap menggunakan sefalosporin asilase untuk mengubah CPC menjadi 7-ACA secara langsung. Beberapa mikroorganisme penghasil sefalosporin asilase yaitu Pseudomonas sp., Bacillus megaterium, Aeromonas sp., dan Arthrobacter. Aktivitas CPC asilase alami sangat rendah dan rekayasa genetik digunakan untuk meningkatkan aktivitasnya.Kata kunci : Sefalosporin, sefalosporin asilase, 7-ACA, rekayasa genetik, mutasi

Abstract

In detergent industry, enzymes are used enormously in terms of quantity and economic value. Lipase catalyzes the hydrolysis of triglycerides into diglycerides and monoglycerides by releasing fatty acids. Lipase is produced by bacteria, fungi, and yeasts. This study aims to determine the potential of Alcaligenes faecalis lipase  for its application  as biodetergen, through stability testing of its lipase activity against detergent components by exposing the enzyme to the commercial detergents, as well as performance testing through washing. Alcaligenes faecalis lipase was produced using Luria Bertani (LB) culture medium supplemented with 1% olive oil inducer. Production is carried out for 24 hours, and the enzyme was harvested at the 18th hour. The harvested enzyme was tested for their stability after being exposed to commercial detergents at a concentration of 1-5%. Results showed that the exposure to the detergents decreased the enzyme activity to 22, 38, 48, 68 and 90%. Performance test showed that the olive oil impurity removal from the fabric was 29%.Keywords: Alcaligenes faecalis Lipase, biodetergent, lipase activities, washing test AbstrakPada industri detergen penggunaan enzim sangatlah besar baik secara jumlah maupun nilai ekonomi.

Abstract

EFFECT OF AUXIN AND CYTOKININ ON MICROPROPAGATION OF BINAHONG (Anredera cordifolia (Tenore) Steenis)Binahong (Anredera cordifolia (Tenore) Steenis) is known as miraculous medicinal plant for its potential to cure for various kinds of diseases such as diabetes, stabilizing blood pressure and circulation, accelerating wound healing, and preventing stroke. In order to provide high quality seedlings of this medicinal plant continuously in large amount, the study on binahong micropropagation was performed. Plant growth regulators of auxins and cytokinins were applied in single or in combination so as to observe their effect on the growth of binahong explants. The results showed that 2,4-D induced callus formation in large diameter on all treatments. Nevertheless, this plant growth regulator had a negative effect on growth and development of shoot and leaves. In the combination treatments between IAA and BAP, it revealed that the higher the concentration of BAP in the media, the lower the number of leaves initiated on shoot explants. Increasing the concentration of IAA upto 1.5 ppm influenced the increasing of shoot tallness and the number of internodes. Our results can be useful for improving the binahong shoot propagation efficiency, as well as callus culture studies.Keywords: Auxin, cytokinin, callus, micropropagation, medicinal plantABSTRAKBinahong (Anredera cordifolia (Tenore) Steenis) dikenal sebagai tanaman obat ajaib karena dapat digunakan untuk pengobatan berbagai macam penyakit seperti diabetes, melancarkan peredaran dan tekanan darah, mempercepat penyembuhan luka, mencegah stroke. Dalam mendukung ketersediaan bibit tanaman obat herbal yang berkualitas secara berkelanjutan maka dilakukan kajian tentang perbanyakan bibit tanaman binahong. Zat pengatur tumbuh auksin dan sitokinin dalam bentuk tunggal maupun kombinasi diaplikasikan pada penelitian ini untuk melihat pengaruhnya terhadap berbagai eksplan binahong. Hasilnya menunjukkan bahwa 2,4-D merangsang pembentukan kalus dengan ukuran yang besar pada semua perlakuan. Namun demikian zat pengatur tumbuh ini memberikan pengaruh negatif terhadap pertumbuhan dan perkembangan tunas dan daun. Dari perlakuan kombinasi zat pengatur tumbuh IAA dan BAP, pertambahan konsentrasi BAP di dalam media menurunkan jumlah daun yang terbentuk pada eksplan pucuk binahong. Demikian pula dengan pertambahan konsentrasi IAA hingga 1,5 ppm sangat berpengaruh terhadap pertumbuhan meninggi tunas dan pertambahan jumlah ruas. Hasil dari studi ini dapat dimanfaatkan untuk studi lanjutan dalam meningkatkan efisiensi perbanyakan tunas serta kultur kalus binahong.Kata kunci: Auksin, sitokinin, kalus, perbanyakan mikro, tanaman obat herbal

Abstract

Taro or Satoimo (Colocasia esculenta (L) Schott var antiquorum) is an alternative of non-rice food. To support saitomo mass cultivation in several regions in Indonesia, shoot multiplication and induction of satoimo microtuber through in vitro technique is amongst the stage to be undertaken. The aims of this study were to determine the effect of BAP (benzylaminopurine) and sucrose for shoot multiplication and microtuber induction of in vitro culture of satoimo. The experiment was arranged in two factors: BAP (0, 1, 2 and 3 mg/L) and sucrose (30, 60, 90 and 120 g/L). The result showed that the single effect of BAP or sucrose and interaction of both significantly increased the number of shoots. The effect of 2 mg/L BAP was more homogeneous than that of 1 and 3 mg/L BAP. Sucrose with the concentration of 30 g/L was the best concentration for shoot multiplication. The highest number of microtuber was achieved with 2 mg/L BAP + 30 g/L sucrose treatments, but tended to decrease due to increasing sucrose concentration. In 2 and 3 mg/L BAP treatments, the number of microtuber increased along with the increasing sucrose concentration.Keywords: satoimo, in vitro shoot, microtuber, benzylaminopurine, sucrose ABSTRAKSatoimo (Colocasia esculenta (L) Schott var antiquorum) merupakan bahan pangan alternatif non-beras. Untuk mendukung produksi massal satoimo di beberapa wilayah di Indonesia, multiplikasi tunas dan induksi umbi mikro secara in vitro merupakan tahapan yang harus dilakukan. Tujuan penelitian ini adalah untuk mengetahui pengaruh BAP dan sukrosa terhadap multiplikasi tunas dan induksi umbi mikro satoimo dalam kultur in vitro. Perlakuan terdiri dari 4 taraf konsentrasi BAP (0, 1, 2 dan 3 mg/L) dan 4 taraf konsentrasi sukrosa (30, 60, 90 dan 120 g/L). Hasil penelitian menunjukkan bahwa BAP dan sukrosa secara tunggal serta interaksinya berpengaruh nyata terhadap multiplikasi tunas in vitro. Pengaruh konsentrasi BAP 2 mg/L lebih homogen dibandingkan perlakuan BAP 1 dan 3 mg/L. Sukrosa 30 g/L merupakan konsentrasi terbaik untuk multiplikasi tunas. Umbi mikro terbanyak terdapat pada perlakuan BAP 1 mg/L + sukrosa 30 g/L tetapi cenderung mengalami penurunan jika konsentrasi sukrosa dinaikkan pada konsentrasi BAP tetap. Pada perlakuan BAP 2 dan 3 mg/L jumlah umbi mikro yang terbentuk cenderung meningkat seiring dengan peningkatan konsentrasi sukrosa.Kata kunci: satoimo, tunas in vitro, umbi mikro, benzilaminopurin, sukrosa

Abstract

INDUCTION MUTATION AND SELECTION OF IN VITRO PLANT OF WHEAT (Triticum aestivum L.)The goal of this research was to produce wheat crop which is tolerant to lowland condition.Six varieties were used, Dewata, Selayar, Alibey, Oasis, Rabe and HP1744. This research consisted of 4 stages: production of the best callus on MS medium containing 3 g/L 2.4-D, induced mutation of embryogenic callus using EMS, in vitro selection of callus at temperature of 27–35°C, and callus regeneration. The best result for callus production was 76% for Dewata and 70% for Selayar varieties. Higher concentration of EMS and longer soaking time decreased the percentage of callus growth. LC50 for Dewata was 0.3% EMS at 30 minutes and that for Selayar was 0.1% EMS at 60 minutes. The higher the temperature was, the lower was the adaptation tolerant of the plants, and callus growth was inhibited. At the highest temperature (35°C) the callus did not grow at all.Keywords: Induced mutation, Triticum aestivum, EMS, in vitro selection, callusABSTRAKTujuan penelitian ini adalah untuk merakit tanaman gandum yang toleran pada dataran rendah. Varietas yang digunakan ada 6 yaitu Dewata, Selayar, Alibey, Oasis, Rabe dan HP-1744. Penelitian terdiri atas empat tahap yaitu induksi pembentukan kalus terbaik menggunakan media MS + 3 g/L 2,4-D (dipilih dua varietas yang terbaik), induksi mutasi kalus embriogenik menggunakan EMS, seleksi kalus in vitro pada suhu 27–35°C, dan regenerasi. Hasil induksi kalus terbaik terdapat pada varietas Dewata sebesar 76% dan Selayar sebesar 70%. Semakin tinggi konsentrasi EMS dan semakin lama waktu perendaman yang digunakan maka semakin menurun persentase pertumbuhan kalus. LC50 varietas Dewata adalah EMS 0,3% waktu 30 menit sedangkan LC50 varietas Selayar adalah EMS 0,1% waktu 60 menit.Semakin tinggi suhunya maka semakin berkurang toleran adaptasi tanaman tersebut, dan pertumbuhan kalus semakin sedikit. Bahkan pada suhu tertinggi yaitu suhu 35°C tidak ada pertumbuhan kalus sama sekali.Kata Kunci: Induksi mutasi, Triticum aestivum, EMS, seleksi in vitro, kalus
