  • TERAPI GEN: DARI BIOTEKNOLOGI UNTUK KESEHATAN GENE THERAPY: FROM
           BIOTECHNOLOGY TO HEALTH

    • Authors: Dyah Ayu Widyastuti
      Abstract: Abstrak Rekayasa genetika dilakukannya untuk manipulasi gen-gen tertentu sehingga ekspresi gen dapat dikontrol dan produknya dapat dimanfaatkan untuk tujuan tertentu, salah satunya untuk pengobatan penyakit dengan terapi gen. Terapi ini melibatkan transfer asam nukleat berupa DNA ke sel embrionik maupun somatik pasien sehingga gen tersebut memiliki efek pengobatan terhadap penyakit pasien. Gen fungsional yang ditransfer berperan menggantikan fungsi gen abnormal yang menyebabkan penyakit tertentu. Terapi gen dapat dilakukan pada sel embrional (germ line gene therapy) maupun sel somatik (somatic cells gene therapy) pada pasien secara in vivo maupun ex vivo. Penyisipan gen pada terapi ini menggunakan vektor virus maupun non virus. Keberhasilan terapi gen salah satunya tergantung pada efektifitas transfer gen yang dilakukan dan ekspresi gen fungsional. Gen fungsional yang telah tertransfer selanjutnya harus diekspresikan dengan baik sehingga terapi dapat berhasil. Kanker merupakan salah satu penyakit yang memungkinkan dilakukannya terapi gen, terkait dengan adanya abnormalitas gen penyebab proliferasi sel yang tidak terkontrol. Abstract Genetic engineering has the ability to manipulate specific genes so its expression can be controlled. The control of gene expression can be used as a gene functional for appropriate purposes, such as diseases cure with gene therapy. This therapy involves DNA as nucleic acid which is transfer to embryonic or somatic cells of patients with certain diseases. The purpose of the gene therapy is to switch an abnormal gene to be a functional gene which has a cure effect for the disease. The functional gene has to substitute the abnormal gene leads to certain disease, either germ line gene therapy or somatic cells therapy. The gene therapy needs a vector to carry the functional gene to targeted cells, in vivo or ex vivo. The vector can be used viral or non viral vectors. The possibilities of achievement of its therapy depend on gene transfer effectiveness and also functional gene expression. The cancer is the one of diseases which can be treated with the gene therapy due to its uncontrolled gene of cell proliferation.

           SEFALOSPORIN C DARI KAPANG Acremonium chrysogenum CB2/11/1 INFLUECE OF
           ADDITION DL-METIONIN IN CULTIVATION MEDIUM TO PRODUCE CEPHALOSPORIN C FROM
           FUNGI Acremonium chrysogenum CB

    • Authors: Eni Dwi Islamiati, Khaswar Syamsu, Erwahyuni E Prabandani
      Abstract: Abstrak Sefalosporin merupakan antibiotik  β-laktam yang mempunyai efektivitas dalam melawan bakteri Gram positif dan negatif. Antibiotik ini dihasilkan oleh kapang Acremonium chrysogenum. Media kultivasi yang optimum dapat meningkatkan produksi sefalosporin. Komposisi media kultivasi yang paling berpengaruh adalah induser. Induser dapat meningkatkan produksi sefalosporin dari kapang A. chrysogenum. Penelitian ini bertujuan untuk melihat pengaruh metionin dalam media produksi sefalosporin dari kapang A. chrysogenum CB 2/11/1. Inokulum A.chrysogenum dibiakkan pada media kultivasi sefalosporin tanpa penambahan DL-metionin  dan  pada media kultivasi  dengan penambahan DL-metionin. Penentuan level konsentrasi DL-metionin dirancang menggunakan Rancangan Acak Lengkap 1 faktor pada tiap-tiap proses penentuan nutrisi. Data yang diperoleh dari masing-masing perlakuan dianalisis sidik ragam pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa metionin sebagai induser dapat meningkatkan produksi sefalosporin sebesar 1,2 kali dibandingkan dengan media kultivasi yang tanpa menggunakan metionin. Pada pengujian level konsentrasi DL-metionin menunjukkan bahwa konsentrasi terbaik metionin adalah 0,4 g/L menghasilkan sefalosporin sebesar 3989 mg/L. Abstract Cephalosporins is a β-lactam antibiotic that has effectiveness against Gram-positive and negative bacteria. This antibiotic is produced by Acremonium chrysogenum. Optimum cultivation medium can increase the production of cephalosporins. The most influential cultivation medium composition is an inducer that increases production of cephalosporin from the fungi. The objective of this study was to investigate the influence of methionine in the cephalosporin production medium containing A. chrysogenum CB 2/11/1, with DL-methionine as the inducer. The inoculum was cultivated in the cultivation media containing cephalosporins without the addition of DL-metionin and in the media with the addition of DL-metionin. The result showed that the DL-methionine increased cephalosporins production 1.2 fold compared to those without using methionine. The assay on the concentration level of DL-methionine showed the best concentration methionine of 0.4 g/L produced cephalosporin by 3989 mg/L.

Indeks kekayaan jenis pada fase vegetatif (0<2,6229≤4) dan generatif (0<3,8287≤4) dari agroekosistem kedelai tanpa aplikasi insektisida tergolong sedang. Komunitas Hymenoptera parasitoid pada agroekosistem kedelai tanpa aplikasi insektisida memiliki kemiripan lebih rendah daripada yang dengan aplikasi insektisida. Aplikasi insektisida mempengaruhi indeks kekayaan jenis pada fase generatif dan kemiripan komunitasnya, yaitu nilainya lebih rendah daripada yang tanpa insektisida. Abstract The management system of soybean agroecosystem with an intensive use of synthetic insecticides will reduce the diversity of parasitoid Hymenoptera species. The study aimed to compare the diversity of the parasitoids in soybean agroecosystem with and without insecticide application. The collection of the parasitoid used insect net and yellow tray. The results showed that the diversity index of the parasitoids during vegetative and generative growth of the soybean with the insecticide application was lower than the one without the insecticide application, which both were classified as moderate. The evenness indices during vegetative and generative growth were high. The richness index in vegetative phase with insecticide application was classified as low (0<2.3955≤2.5), while in the generative phase was classified as moderate (0<3.6118≤4). The richness index on the vegetative (0<2.6229≤4) and generative (0<3.8287≤4) from the agroecosystem soybean without insecticide application were classified as moderate. The similarity without insecticide application was lower than the one with insecticide application. The application of insecticide affects the species richness index (in the generative phase) and the similarity, that the value is lower than the one without insecticide.

      Abstract: AbstrakPenambatan nitrogen oleh bakteri rhizosfer dapat dimanfaatkan untuk menyiasati dampak salinitas pada tanah sawah pesisir. Kemampuan tersebut disebabkan oleh aktivitas nitrogenase yang disandikan gen nifH pada komponen II. Penelitian  ini bertujuan  menganalisis aktivitas nitrogenase pada kondisi salin dan mengidentifikasi gen nifH. Sebanyak 50 isolat bakteri rhizosfer asal tanah sawah pesisir daerah Eretan dan Patimban, Jawa Barat telah dianalisis. Lima isolat yang menunjukkan aktivitas nitrogenase pada kondisi salin adalah Er B1 3, Er B1 4, Er B1 9, Er B2 10, dan Ptb B1 4. Gen nifH kelima sampel diidentifikasi menggunakan PCR menghasilkan amplikon berukuran ~360 bp. Aktivitas nitrogenase tertinggi berdasarkan Analisis Reduksi Asetilen (ARA) diperoleh pada isolat Er B2 10 yang memiliki kekerabatan terdekat dengan bakteri Providencia sp. Hasil yang diperoleh membuktikan bahwa beberapa bakteri asal sawah pesisir dapat menambat nitrogen pada kondisi salin.AbstractThe ability of nitrogen fixation by rhizosphere bacteria could be used to decrease salinity impact in coastal paddy field, due to nitrogenase capability, encoded by a nifH gene in component II. The objectives of this research are to analyze nitrogenase activity in saline condition and identify the presense of the nifH gene. A total of 50 isolates of the rhizosphere bacteria coastal from wetland areas of Eretan and Patimban, West Java, has been isolated and being analyzed. Among them, five isolates i.e. Er B1 3, ER B1 4, Er B1 9, Er B2 10 and Ptb B1 4, showed the nitrogenase activity under saline condition. The polymerase chain reaction (PCR) of the nifH gene from those five samples resulted in the amplicon size of  ~360 bp. The highest activity of nitrogenase assessed by acetylene reduction assay (ARA) was shown by Er B2 10 which closely related to bacteria of Providencia sp. The obtained result showed that several bacteria from coastal paddy field were able to conduct nitrogen fixation under saline stress.

    • Authors: Mayta Novalida Isda, Siti Fatonah, Lia Novita Sari
      Abstract: AbstrakGarcinia mangostana L. merupakan salah satu spesies dari famili Guttiferae kaya senyawa dari golongan xanthon. Manggis memiliki juvenil yang lama. Salah satu metode yang dapat memecahkan masalah dalam perbanyakan tanaman manggis dalam jumlah yang banyak, bisa sepanjang musim dan menghasilkan tanaman yang seragam yaitu kultur in vitro. Tujuan dari penelitian ini adalah untuk menentukan konsentrasi terbaik antara Benzil Amino Purin (BAP) dan madu terhadap induksi tunas dari eksplan biji manggis yang belah tiga melintang  secara in vitro. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan BAP (0;3 mg/L) dan madu (3;6 mg/L) pada media MS (Murashige-Skoog) dengan pengamatan 70 hari setelah tanam (hst). Hasil penelitian menunjukkan bahwa pemberian BAP maupun madu mampu meningkatkan pembentukan tunas. Pemberian BAP dan madu berpengaruh nyata terhadap persentase terbentuknya tunas, waktu muncul tunas, jumlah tunas dan panjang tunas.  Jumlah tunas terbanyak terdapat pada perlakuan 3 mg/L BAP sebanyak 20 tunas per biji. Kombinasi perlakuan dengan penambahan 3 mg/L BAP + 3 ml/L madu menghasilkan persentase terbentuk tunas tertinggi (100%); waktu muncul tunas tercepat 12,75 hst; dan panjang tunas tertinggi 1,86 cm. Pada penelitian ini telah berhasil menginduksi tunas dari biji manggis yang dibelah tiga melintang asal Bengkalis dengan penambahan BAP dan madu.AbstractGarcinia mangostana L. is one of the species within the family Guttiferae that rich in compounds from the class of xanthon. Mangosteen has time juvenile problems. One method that can solve the problem in the mangosteen plant propagation which can be produced in a large number in all season and uniform is in vitro culture. The purpose of this study was to determine the best concentration of BAP and honey to induce the formation of shoot from explants of mangosteen seeds split transversely into three pieces by in vitro method. This study used a Completely Randomized Design (CRD) with a treatment of BAP (0;3 mg/L) and honey (3;6 mg/L) on MS medium with 70 days of observation. The results showed that the BAP and honey can improve the formation of shoots. The addition of BAP and honey significantly affected the percentage of the formed shoots, the period of shoots appear, the number of shoots and shoot length. The treatment of 3 mg/L BAP resulted in the most shoots formed as many as 20 shoots per seed. The combined treatment 3 mg/L BAP + 3 ml/L of honey produced 100% of the formed shoots; fastest period of shoots appear (12.75 DAS); and the longest shoot (1.86 cm). Therefore, the addition of BAP and honey to the three transversely-split mangosteen seeds from Bengkalis origin successfully induced the formation of the shoot.
