Abstract

Pengaruh Suplai Nitrogen pada Media Kultur dan Intensitas Cahaya Terhadap Proses Fotosintesis Chlamydomonas reinhardtiiOrganisms use nitrogen to produce, among others, amino acids, proteins, and nucleic acids. In this study, the effects of various concentrations of ammonium in culture media on the photosynthetic performance of Chlamydomonas reinhardtii were done under two light conditions: low and high intensity. The microbes were grown at low (75% NH4Cl dosage), normal (100% NH4Cl dosage, which was 2 M NH4Cl), and high (125% NH4Cl dosage) nitrogen content. Cells density and chlorophyll content were quantitatively determined. Immunoblotting technique was used to separate proteins based on molecular mass. In both low and high light intensity, cells grown in 75% NH4Cl dosage culture medium showed lower cell density and chlorophyll concentration than those grown in 100% and 125% NH4Cl dosage media. The later two media produced almost the same amount of cell density and chlorophyll concentration. In conclusion, 75% NH4Cl dosage was insufficient for C. reinhardtii cells to grow well. The results also showed that accumulation of photosystem I (PsaA and PsaD/F) and light harvesting complex II (LHCII) were higher in low light than in high light intensity.AbstrakOrganisme menggunakan nitrogen diantaranya untuk memproduksi asam amino, protein, dan asam nukleat. Dalam percobaan ini pengaruh berbagai konsentrasi amonium dalam media pada fotosintesis Chlamydomonas reinhardtii dilakukan di bawah dua kondisi cahaya: intensitas rendah dan tinggi. C. reinhardtii ditumbuhkan dalam medium dengan dosis nitrogen (N) rendah (75% dosis NH4Cl), normal (100% dosis NH4Cl, yakni NH4Cl 2 M), dan tinggi (125% dosis NH4Cl). Parameter yang diukur adalah  kepadatan sel dan konsentrasi klorofil. Analisis protein dilakukan dengan imunobloting untuk memisahkan protein berdasarkan massa molekul. Pada intensitas cahaya rendah dan tinggi, sel-sel pada medium dengan 75% NH4Cl menunjukkan kepadatan sel dan konsentrasi klorofil lebih rendah dibandingkan dengan 100% NH4Cl dan 125% NH4Cl, di mana kedua media ini menghasilkan kepadatan sel maupun konsentrasi klorofil yang hampir sama. Dengan demikian dapat disimpulkan bahwa 75% NH4Cl tidak cukup bagi C. reinhardtii untuk tumbuh dengan baik. Selain itu, akumulasi fotosistem I (PsaA dan PsaD/F) dan kompleks pemanenan cahaya II (LHCII) lebih tinggi pada sistem fotosintesis dengan intensitas cahaya rendah dibandingkan cahaya tinggi.Kata kunci: Chlamydomonas reinhardtii, fotosintesis, intensitas cahaya, klorofil, nitrogen

Abstract

Concentration of active compounds contained in medicinal plants is determined by genetic factors as well as growth environment. In sambiloto plants both factors have major impacts on the formation of diterpene lactone, andrographolide. Variation of sampling time, cultivation, and processing methods causes variation in the content of active compounds of the same plant. The purpose of this study was to determine andrographolide concentration of sambiloto plants obtained from 12 different locations with various planting conditions in Java Island. andrographolide content of sambiloto was extracted by methanol and analyzed using HPLC. The results showed that the concentrations of andrographolide varied from 0.29 to 4.44% with an average of 2.19% on dry weight basis. The highest concentration of 4.44% was detected in sambiloto accession from Wonokaton Village, Pasuruan Regency while the lowest one was from Conggeang Kulon Village, Sumedang Regency. Three sambiloto accessions had potential to be further developed as their andrographolide concentrations were above 3%, which was higher than those from all the others.Keywords: Andrographis paniculata, andrographolide, active coumpound, HPLC, Java island ABSTRAKKadar senyawa aktif yang terkandung pada tanaman obat selain dipengaruhi oleh faktor genetik juga dipengaruhi oleh faktor lingkungan tumbuhnya. Pada tanaman sambiloto kedua faktor tersebut berpengaruh sangat besar pada pembentukan diterpen lakton, andrographolide. Adanya variasi pada waktu pengambilan sampel, tempat penanaman, metode pengolahan dan lain sebagainya berakibat pada perbedaan dalam kandungan senyawa aktif pada tanaman yang sama. Tujuan dari penelitian ini adalah untuk mengetahui kadar andrographolide dari tanaman sambiloto yang diambil dari 12 lokasi tumbuh dengan kondisi penanaman yang berbeda di Pulau Jawa. Daun tanaman sambiloto diekstrak dengan methanol kemudian dianalisis kandungan andrographolide menggunakan HPLC. Kadar andrographolide yang dihasilkan bervariasi berkisar antara 0,29-4,44% dengan kadar rata-rata adalah 2,19% berat kering. Kadar tertinggi didapatkan pada aksesi dari Desa Wonokaton Kabupaten Pasuruan dengan kadar andrographolide adalah 4,44% sedangkan kadar yang terendah didapatkan pada aksesi dari Desa Conggeang Kulon, Kab. Sumedang. Berdasarkan data kandungan andrographolide, diperoleh 3 aksesi sambiloto yang potensial untuk dikembangkan menjadi aksesi unggulan karena kadar andrographolidenya di atas 3%, melebihi semua yang lain.Kata kunci: Andrographis paniculata, andrographolide, senyawa aktif, HPLC, pulau Jawa

Abstract

Effects of Lactic Acid Bacteria Combination on Characteristic Change of Buffalo Milk Nutrition Determination of physical and chemical characteristics on fermented milk using a mixture of Lactobacillus bulgaricus, Streptococcus thermophilus, and Bifidobacterium sp. has been conducted. Fermentation was carried out for 20 hours at 37ºC in a facultative aerobic condition. Physical characteristics were performed by comparing the physical properties before and after fermentation such as viscosity and texture, including chemical properties such as pH, acidity, protein, fat, and sugar contents. Inoculants of lactic acid bacteria were varied using a combination of lactic acid bacteria mixture. Results showed that the combination of bacteria inoculants used has no significant effect on changes in protein, fat, ash, and water contents. However, the effects on total acid, pH, sugar content, and physical appearance such as viscosity and texture were significant. The combination of L. bulgaricus, S. thermophilus and Bifidobacterium sp. (A6) produced a soft texture appearance and high viscosity. The combination of inoculant bacteria L. bulgaricus with S. thermophilus (A5) produced a texture similar to A6 but with a lower viscosity than A6.Keywords: Lactobacillus bulgaricus, Streptococcus thermophilus, Bifidobacterium sp, buffalo milk, fermentation. ABSTRAKPenelitian untuk mengetahui karakteristik fisik dan kimia hasil fermentasi susu kerbau menggunakan campuran Lactobacillus bulgaricus, Streptococcus thermophilus, dan Bifidobacterium sp telah dilakukan. Fermentasi dilakukan selama 20 jam pada suhu 37ºC secara aerobe fakultatif. Karakteristik fisika dilakukan dengan membandingkan sifat fisik seperti kekentalan dan tekstur, serta sifat kimia yang meliputi kandungan protein, lemak, gula, pH, keasaman sebelum dan sesudah fermentasi. Inokulan bakteri asam laktat divariasikan menggunakan kombinasi campuran bakteri asam laktat. Hasil penelitian menunjukkan bahwa kombinasi inokulan yang digunakan dalam proses fermentasi susu kerbau tidak berpengaruh nyata terhadap perubahan kadar protein, lemak, abu, dan air. Namun demikian berpengaruh nyata terhadap total asam, pH, kadar gula, dan penampakan fisik seperti kekentalan dan tekstur. Kombinasi inokulan L. bulgaricus, S. thermophilus dan Bifidobacterium sp. (A6) menghasilkan susu fermentasi dengan penampakan tekstur halus dan kekentalan yang lebih padat.

Abstract

D-amino acid oxidase (DAAO) is a flavin adenine dinucleotide-containing enzyme that catalyzes the oxidative deamination of amino acid D-isomers with high stereospecificity, which results in α-keto acids, ammonia and hydrogen peroxide. Having high stereospecificity, DAAO is used in a variety of applications such as drug, biocatalyst, biosensor and preparation of transgenic plants. DAAO is widespread in nature, found in microorganisms to mammals. Microbial DAAO is considered more important than mammalian DAAO for biotechnology application. DAAO production in submerged fermentation is influenced by several factors, such as carbon source, nitrogen source, inducer, dissolve oxygen, temperature and pH. The influence of those factors on DAAO production by microbial origin, DAAO production by microbial recombinant, and its application in biotechnology are discussed in this review.Keywords: Enzyme, DAAO, D-amino acid, production, application ABSTRAKEnzim D-asam amino oksidase (DAAO) merupakan enzim yang mengandung Flavin Adenine Dinucleotide yang bekerja mengkatalisis reaksi oksidasi deaminasi D-asam amino dengan stereospesifisitas yang tinggi menghasilkan α-asam keto, amonia dan hidrogen peroksida. Karena mempunyai karakteristik sreteospesifisitas yang tinggi, enzim DAAO banyak digunakan untuk berbagai aplikasi seperti obat, biokatalis, biosensor dan penyiapan tanaman transgenik. Enzim ini dapat dihasilkan oleh organisme mulai dari bakteri hingga mamalia, namun untuk aplikasi dibidang bioteknologi, enzim DAAO yang berasal dari mikroorganisme dipandang lebih penting dari pada yang berasal dari mamalia. Produksi enzim dari DAAO dari mikroorganisme dalam kultur cair dipengaruhi oleh beberapa faktor seperti sumber karbon, nitrogen, senyawa penginduksi, oksigen terlarut, temperatur dan pH medium. Pengaruh dari faktor-faktor tersebut terhadap produksi enzim DAAO, produksi enzim DAAO menggunakan mikroba rekombinan serta aplikasinya dalam bidang bioteknologi dibahas dalam tinjauan.Kata Kunci: Enzim, DAAO, D-asam amino, produksi, aplikasi

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

Abstract

To reduce broiler production cost, a study was carried out on utilisation of alternative, less costly feed components, namely kepok banana peel and corn hominy which were mixed and fermented using the fungus Rhizopus oryzae. The fermented substrate was added into commercial feed in order to determine its influence on the poultry’s production performance. This study employed a completely randomized design (CRD) with four treatments: one using 100% pure commercial feed, and the other three commercial feed mixed with the fermented feed component at the levels of 5%, 10% and 15%. All treatments were repeated four times during 25 days growth period. The results showed that supplementation of the fermented ingredient in the broiler ration at the levels of 5%, 10%, or 15% had no significant effect (P>0,05) on the feed consumption, body weight gain, feed conversion ratio, and the final body weight of the animals. Although mixing the fermented feed ingredient up to 15% in the commercial feed promoted the growth of the broilers, the results were not yet comparable to pure commercial feed.Keywords: Corn hominy, broiler, fermentation, kepok banana peel, Rhizopus oryzae AbstrakUntuk mengurangi biaya produksi ayam pedaging, dilakukan pengkajian penggunaan bahan penyusun pakan alternatif yang lebih murah, yaitu kulit pisang kepok dan ampok jagung yang dicampur dan difermentasi menggunakan jamur Rhizopus oryzae. Hasil fermentasi tersebut lalu ditambahkan pada pakan komersial ayam pedaging dengan tujuan mengetahui pengaruhnya terhadap penampilan produksi ayam pedaging. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan, yaitu satu perlakuan 100% pakan komersial murni, dan tiga perlakuan pakan komersial yang dicampur bahan pakan hasil fermentasi tersebut dengan kadar 5%, 10%, dan 15%. Seluruh perlakukan diulang empat kali selama 25 hari masa pemeliharaan. Hasil penelitian menunjukkan bahwa penambahan bahan pakan terfermentasi ke dalam ransum ayam pedaging pada kadar 5%, 10%, atau 15% tidak memberikan pengaruh nyata (P>0,05) terhadap konsumsi pakan, pertambahan bobot badan, nilai koversi pakan, dan bobot badan akhir hewan. Meskipun penambahan bahan pakan fermentasi tersebut hingga 15% dalam pakan komersial mendukung pertumbuhan ayam pedaging, namun capaian pertumbuhannya belumlah sebaik pakan komersial.Kata kunci: Ampok jagung, ayam pedaging, fermentasi, kulit pisang kepok, Rhizopus oryzae
