    • Authors: Yuwono Prianto, Swara Yudhasasmita
      Abstract: Abstrak Genetically modified organism (GMO) merupakan organisme yang gen-gennya telah diubah dengan menggunakan teknik rekayasa genetika. Produk rekayasa genetika diklasifikasikan menjadi 4 macam, yaitu generasi pertama: satu sifat; generasi kedua: kumpulan sifat; generasi ketiga dan keempat: near-intragenic, intragenic, dan cisgenic. Adapun produk rekayasa genetika pada tanaman di Indonesia di antaranya adalah padi, tomat, tebu, singkong, dan kentang. Regulasi tanaman hasil rekayasa genetika diatur oleh beberapa lembaga, di antaranya Kementerian Lingkungan Hidup, Kementerian Pertanian, Komisi Keamanan Hayati, Tim Teknis Keamanan Hayati, dan Biosafety Clearing House, berdasarkan peraturan pemerintah No. 21 tahun 2005. Pengujian yang dilakukan pada produk rekayasa genetika meliputi analisis sumber gen penyebab alergi, sekuens homolog asam amino, resistensi pepsin, skrining serum, serta penggunaan hewan uji. Berbagai produk GMO di Indonesia sejauh ini merupakan produk yang dibutuhkan dalam memenuhi kebutuhan hidup sehari-hari, yang perlu diawasi secara ketat dari segi dampaknya terhadap lingkungan melalui ketentuan hukum yang berlaku, yang diwakili oleh instansi-instansi terkait tersebut.Abstract Genetically modified organism (GMO) is an organism whose genes that have been altered by using genetic engineering techniques. Genetic engineering products are classified into 4 types, which are the first generation: one trait; the second generation: a collection of properties; the third and fourth generation: near-intragenic, intragenic, and cisgenic. The genetic engineering products in plants in Indonesia include rice, tomatoes, sugar cane, cassava, and potatoes. The application of the genetically engineered crops is regulated by several institutions, including the Ministry of Environment, the Ministry of Agriculture, the Biosafety Commission, the Biosafety Technical Team and the Biosafety Clearing House, under government regulation No. 21 of the year 2005. Assessment for GMO product can be conducted by analyzing the source of an allergic gene, sequence homology of amino acid, resistance to pepsin, serum screening and use of an animal model. The GMO products in Indonesia are required so far to meet the needs of daily use, which need to be closely monitored in terms of their impact on the environment through the legal provisions, represented by the respective agencies.

    • Authors: Arina Aisyah, Wibowo Mangunwardoyo, Trismilah Trismilah, Dadang Suhendar
      Abstract: Abstrak Lipase diketahui memiliki peranan penting dalam bidang industri. Produksi lipase dapat dihasilkan oleh kapang, khamir, dan bakteri. Penelitian bertujuan untuk meningkatkan aktivitas lipase yang dihasilkan oleh Bacillus halodurans CM1. Aktivitas lipase dapat ditingkatkan dengan optimasi komposisi media, mutasi bakteri dengan radiasi gamma dan N-methyl-N’-nitro-N-nitrosoguanidine (NTG). Enzim yang dihasilkan dipekatkan dengan metode stirred-cell ultrafiltration (UF)-ammonium sulfat dan UF-Polyethylene glycol (PEG). Uji aktivitas dilakukan pada tujuh media yang berbeda untuk mendapatkan media produksi. Delapan variabel komposisi media dioptimasi dengan rancangan Plackett-Burman. Bakteri dimutasi dengan radiasi gamma dosis 0,1–0,4 kGy dan NTG 0,05–0,15 mg/mL dengan waktu inkubasi 1–3 jam. Hasil penelitian menunjukkan bahwa media produksi yang digunakan berdasarkan optimasi media dan komposisi media Plackett-Burman adalah media dasar Bora & Bora yang mengandung 0,5% palm oil (PO) dan 0,09% CaCl2. Aktivitas lipase optimal diproduksi oleh bakteri hasil mutasi dengan NTG 0,1 mg/mL yang diinkubasi selama 3 jam. Pemekatan enzim UF-ammonium sulfat dan UF-PEG mampu meningkatkan aktivitas enzim lipase sebesar 18,44%.  Abstract Lipase is known to have an important role in the industrial field. Lipase can be produced by molds, yeasts, and bacteria. The research aimed to increase the activity of lipase produced by Bacillus halodurans CM1. Lipase activity can be improved by optimization of the composition of the media, the mutation of bacteria with gamma radiation and N-methyl-N'-nitro-N-nitrosoguanidine (NTG). The enzyme was concentrated by stirred-cell ultrafiltration method (UF)-ammonium sulfate and UF-Polyethylene glycol (PEG). The activity test was performed on seven different media to get production media. The eight variables of the media composition were optimized by Plackett-Burman design. The bacteria were subject to mutation by using 0.1–0.4 kGy dose of gamma radiation and 0.05–0.15 mg/mL NTG with incubation time for 1–3 hours. The results showed that the production media used based on optimization and composition of Plackett-Burman media was Bora Bora medium that containing 0.5% palm oil (PO) and 0.09% CaCl2. Optimum lipase activity was produced by the bacterium that mutated with 0.1 mg/mL NTG, incubated for 3 hours. The concentrated by UF-ammonium sulfate and UF-PEG could increase the lipase activity by 18.44%.

           Hasil Poliploidisasi dengan Kolkisin

    • Authors: Meiliana Friska, Budi Setiadi Daryono
      Abstract: ABSTRAKJahe merah (Zingiber officinale Roxb. var. rubrum Rosc.) merupakan salah satu tanaman jamu-jamuan yang banyak digunakan sebagai bumbu masakan, bahan obat tradisional, manisan, minuman penyegar, dan sebagai bahan komoditas ekspor nonmigas. Rimpang pada jahe memiliki manfaat untuk kesehatan kesegaran, dan campuran untuk membuat masakan. Rasa pedas yang ditimbulkan pada jahe disebabkan adanya senyawa keton ‘gingerol’. Penelitian ini bertujuan untuk mendapatkan tanaman poliploid pada jahe merah dengan mengamati perubahan karakter fenotip pada daun, batang dan rimpang hasil induksi kolkisin. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Kelompok (RAK) pola faktorial dengan dua faktor yaitu konsentrasi kolkisin (0,05%, 0,1%, and 0,2%) dan waktu perendaman (6, 12, dan 24 jam). Hasil pengamatan dianalisis dengan Analysis of Variance (ANOVA) dan pengolahan data secara statistik dilakukan dengan menggunakan uji F pada taraf α = 5%. Jika menunjukkan perbedaan nyata dilanjutkan dengan uji Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa perubahan karakter fenotip jahe merah hasil induksi kolkisin terlihat pada perlakuan K1W2 (konsentrasi 0,05% lama perendaman 12 jam). Terlihat pada tinggi tanaman, diameter batang semu, jumlah daun, berat rimpang, dan kadar klorofil sedangkan pada panjang daun, lebar daun dan luas daun tidak menunjukkan perbedaan secara signifikan. ABSTRACT Red ginger (Zingiber officinale Roxb. var. rubrum Rosc.) is one of the herb plants that often being used as a spice, traditional medicines, sweets, drinks, and material export commodities. The ginger’s rhizome is the most common because it is good for health freshness, and spice for food. The spicy from the ginger comes from ketone compounds ‘gingerol’. This research aimed to produce polyplody crops in red ginger by observing the changes of phenotype characters on the leaves, stems and rhizome resulted from colchicine induction. This research was based on experimental method with Randomized design with two factors, which were colchicine concentration (0,05%, 0,1% and 0,2%) and incubation time (6, 12 and 24 hours). The data were analyzed using Analysis of Variance (ANOVA) and statistical data processing was done using F test at α = 5%. If the result shows any significant differences then was followed with Duncan Multiple Range Test (DMRT). The results showed that the change in the phenotype characters of red ginger was seen in K1W2 (0,05 % concentration of incubation time 12 hours). Phenotype characters include plant height, stem diameter, number of leaves, rhizome weight and leaf chlorophyll content showed phenotypic characters change significantly while leaf length, leaf width and leaf area did not indicate any change in the character of phenotypes significantly.

  • Vegetasi Komunitas Nepenthes spp. di Kawasan Hutan Kampus Institut Agama
           Islam Negeri Sulthan Thaha Saifuddin Jambi

    • Authors: Try Susanti, Martinis Yamin
      Abstract: Abstrak Nepenthes spp. memiliki nilai ekologi, ekonomi dan ekslusifitas bagi masyarakat pada umumnya, namun eksistensi di habitat alaminya setiap tahunnya semakin terancam. Hal ini disebabkan oleh konversi lahan hutan, semak belukar menjadi kawasan pemukiman, perladangan, perkebunan, pembalakan hutan, degradasi hutan, dan eksploitasi liar, sehingga preservasinya cenderung terabaikan. Penelitian bertujuan mempertelakan secara ilmiah deskripsi dan eksplorasi vegetasi komunitas Nepenthes spp., nilai penting dan indeks keanekaragaman tumbuhan dalam komunitasnya. Metode yang digunakan dalam penelitian adalah metode survei dan teknik pengambilan data mengikuti prosedur kerja ekologi, obervasi, koleksi secara langsung pada sejumlah sampel, serta dokumentasi. Hasil penelitian ditemukan Nepenthes mirabilis dan N. gracilis. Komposisi tumbuhan dalam komunitas Nepenthes spp. tercatat 43 spesies termasuk ke dalam 25 famili. Nilai kepentingan tertinggi adalah Stenoclaena palustris (14,65%), Dicronapteris linearis (17,74%), dan Lygodium microphyllum (12,10%). Indeks keanekaragaman spesies berdasarkan Shannon-Wiener tergolong rendah (1,86). Rendahnya nilai indeks keanekaragaman spesies dalam suatu komunitas dipengaruhi oleh interaksi yang terjadi dalam komunitas tersebut kecil dan gangguan lingkungan alami ataupun kegiatan aktivitas manusia.Abstract Nepenthes spp. have ecology, economy, and exclusivity value to the general people. However, its existence is increasingly threatened every year. The causes are a conversion of the forest, scrub changes into residential areas, fields, plantations, logging, forest degradation, and wild exploitation, while its preservation tends to be neglected. This study was aimed at placing the description and exploration of vegetation Nepenthes spp., important values, and diversity index in its community. The research used a survey method. The data was collected by following work procedures of ecology, observation, direct collection of a number of samples, and documentation. The result showed that there were two species of Nepenthes spp., namely Nepenthes mirabilis and N. gracilis. The composition in the Nepenthes spp. communities consisted of 43 species which belong to 25 families. The highest importance values were found in the species of Stenoclaena palustris (14.65%), Dicronapteris linearis (17.74%), and Lygodium microphyllum (12:10%). The Shannon-Wiener diversity index was relatively low (1.86). The low value of the species diversity index in the community occurred due to the slightly small interactions within the community, the disturbance of natural environment, and the human activities as well.

    • Authors: Marina Silalahi
      Abstract: Abstrak Biji Arenga pinnata memiliki kulit biji  keras dan berlignin sehingga menghambat masuknya air ke dalam biji. Lapisan lignin pada kulit biji dapat didegradasi melalui reaksi kimia maupun perlakuan fisik. Perendaman biji aren dengan asam kuat (HNO3, H2SO4, dan HCl) dan pengamplasan akan mempengaruhi laju imbibisi air melewati kulit biji. Variabel bebas dalam penelitian ini adalah konsentrasi asam kuat (HNO3, H2SO4, dan HCl), luas pengamplasan, air panas, lama perendaman, sedangkan variabel terikat laju imbibisi pada biji aren. Konsentrasi asam kuat yang digunakan adalah 1M dan 0,5M untuk masing-masing HNO3, H2SO4, dan HCl. Pengamplasan dilakukan di bagian pangkal biji, dan luas pengamplasan bervariasi (tanpa amplas, amplas ½ bagian, dan amplas keseluruhan). Setiap perlakuan direndam selama 18, 24 dan 36 jam. Biji aren yang diberi perlakuan fisik maupun kimia mengalami pengelupasan kulit biji. Laju imbibisi biji pada perendaman 24 jam lebih tinggi dibandingkan dengan lama perendaman 18 maupun 36 jam. Laju imbibisi tertinggi terjadi pada waktu perendaman 1M HCl dan amplas penuh dengan lama perendaman 24 jam sebesar 0,038 ± 0,002 mL/jam dan 0,038 ± 0,007 mL/jam . Biji aren yang diberi perlakuan fisik dan kimia mulai berkecambah 7 minggu setelah tanam dengan daya kecambah tertinggi pada pemberian HNO3 dan lama perendaman 18 jam.Abstract Arenga pinnata seed has a hard seed coat and lignin that inhibit the absorption of water into the seed. The lignin in the seed coat can be degraded by chemical or physical treatments. Soaking of the palm seeds into strong acids (HNO3, H2SO4, or HCl) and sanding may affect the imbibition rate. The research was conducted to investigate the effect of a strong acid, sanding, and soaking time to the imbibition rate of A. pinnata seed. The independent variables in this research are concentration of the strong acids HNO3, H2SO4, and HCl; sanding, and soaking time, while the dependent variable is the rate of imbibition of A. pinnata Merr. The concentrations of the strong acid used were 1M and 0.5M. The sanding was performed on the base of seeds, which were varied into without sanding, ½ parts, and full sanding). The soaking durations were for 18, 24 and 36 hours. Palm sugar seeds treated by physical or chemical showed damage of the skin seeds. The seeds soaked with strong acid absorbed more water than the sanding and control treatments. The rate of imbibition for a 24-hour soaking showed imbibition rate higher than the 18 or 36-hour soaking. The highest rates of imbibition occurred on the treatments of 1M HCl soaking and 24 hours full sanding which were 0.038 ± 0.002 mL/h and 0.038 ± 0.007 mL/h, respectively. The seeds by physical and chemical treatments started their germination in seven weeks after planting with the highest germination from the treatments of HNO3 and 18 hours soaking time.

  • Daya Hambat Perak Nitrat (Agno3) pada Perkecambahan Biji Kacang Hijau
           (Vigna radiata)

    • Authors: Muh. Shofi
      Abstract: Abstrak Logam berat banyak digunakan dalam kehidupan manusia, di antaranya Hg, Pb, Cr, Zn, dan Ag. Di antara logam tersebut, logam perak (Ag) banyak digunakan oleh masyarakat untuk kegiatan sehari-hari, seperti dalam fotografi, untuk pembuatan cermin perak, dan sebagai reagen dalam analisis. Logam perak dapat diperoleh dari senyawa AgNO3. Keberadaan logam perak pada tanaman dapat menghambat proses perkecambahan pada tanaman kacang hijau (Vigna radiata), yang ditandai dengan penghambatan pemanjangan sel pada akar. Tujuan penelitian ini adalah untuk mengetahui pengaruh daya hambat terhadap pertumbuhan kecambah kacang hijau dan mengetahui konsentrasi hambatan (Inhibitory Concentration) dari perak nitrat (AgNO3). Berdasarkan hasil penelitian diketahui bahwa terdapat penghambatan pada pembentukan akar dengan rata-rata penghambatan lebih dari 50% pada konsentrasi 462,27 ppm. Hal ditunjukkan pada panjang akar yang lebih pendek seiring dengan tingginya konsentrasi AgNO3. Hal tersebut dapat disimpulkan bahwa konsentrasi AgNO3 berpengaruh pada perkecambahan biji kacang hijau yang ditandai dengan terhambatnya pemanjangan panjang akar kacang hijau.Abstract Heavy metals are widely used in human life, including Hg, Pb, Cr, Zn, and Ag. Among these metals, silver is widely used for human daily activities, such as in photography, for the manufacture of silver mirror, and as reagents in many analysis. Silver metal can be obtained from AgNO3 compounds. The presence of silver metal in a plant may inhibit the germination process in the green bean plant (Vigna radiata) which is characterized by inhibition of cell lengthening in the root. The aims of this research are to investigate the influence of the inhibitory power to green bean growth and the inhibitory concentration of the silver nitrate (AgNO3). The result showed that there was inhibition that occurred in the root formation by more than 50% of average inhibition at the concentration of 462.27 ppm. It was shown that the root was shorter in length along with the high concentration of AgNO3. From that fenomena, it can be assumed that the concentration of AgNO3 influenced the germination of green bean seeds that were characterized by the inhibition on the lengthening of their roots.

           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.

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.
