Abstract

Analisis diversitas genetik memfasilitasi pemilihan tetua untuk program pemuliaan kelapa sawit. Penggunaan marka SSR meningkatkan akurasi dan kecepatan analisis filogenetik aksesi kelapa sawit. Sebagai penanda genetik, marka SSR memiliki keunggulan dibandingkan marka DNA lainnya (AFLP, RAPD, dan RFLP) karena marka SSR polimorfisme alelnya tinggi, bersifat kodominan, berdistribusi hampir merata pada genom, ekonomis dalam pengujiannya, dan mampu mendeteksi keragaman genetik aksesi dengan tingkat kekerabatan dekat. Tujuan dari penelitian ini untuk (1) mendapatkan marka SSR yang dapat digunakan untuk analisis diversitas genetik aksesi-aksesi kelapa sawit; (2) menguji marka SSR terpilih untuk uji diversitas genetik dalam aksesi (intra accession), antar aksesi (inter accessions), dan antar species (inter species) kelapa sawit menggunakan marka mikrosatelit terpilih. Sebanyak 39 marka SSR diuji pada empat genotipe kelapa sawit. Pola pita marka SSR diskor dan tingkat polimorfisme marka dihitung. Marka SSR dipilih berdasarkan tingkat polimorfime, pola pita, frekuensi dan ukuran alel terdeteksi, dan penyebarannya pada kromosom kelapa sawit. Sepuluh individu tanaman anggota aksesi C103-T (aksesi Tenera asal Kamerun) dan 9 anggota aksesi E. oleifera (Eo) asal Amerika Selatan dan 7 aksesi E. guineensis (Eg) diuji menggunakan 20 marka SSR terpilih. Dendogram kekerabatan dibuat dengan metode Unweighted Pair Group Method Arithmetic (UPGMA) menggunakan software NTSYS (Numerical Taxonomy and Multivariate Analysis System) versi 2.1-pc. Hasil penelitian menunjukkan 39 marka SSR memiliki tingkat polimorfisme 75% (berkisar 32-92%), jumlah alel 5,97 (2-14) dengan ukuran alel 119-330 bp. Berdasar tingkat polimorfisme, frekuensi dan ukuran alel dan pola pita tersebut, serta distribusinya yang menyebar merata pada kromosom kelapa sawit, terpilih 20 marka SSR untuk diuji selanjutnya. Marka SSR terpilih ini diuji kemanfaatannya untuk analisis keragaman genetik anggota individu dalam aksesi, individu antar aksesi dalam satu species Eo atau Eg, dan antar species Eo dan Eg. Uji filogenetik 20 marka SSR pada 10 individu anggota aksesi C103-T menghasilkan diversitas genetik 14,37-37,38%. Uji 8 individu anggota aksesi Eo menunjukkan diversitas genetik 7-15%. Uji diversitas genetik aksesi antar species Eo dan Eg menghasilkan diversitas genetik sebesar 15-45%. Dengan demikian 20 marka SSR terpilih dapat membedakan dengan sangat jelas anggota individu dalam aksesi, anggota aksesi dalam suatu sepecies, dan anggota aksesi antar species kelapa sawit. Marka SSR terpilih dapat digunakan untuk uji kekerabatan berbagai aksesi kelapa sawit. Hasil studi ini bermanfaat untuk penanganan plasma nutfah di lapang dan pemilihan calon tetua untuk program pemuliaan kelapa sawit. Kata kunci : Kelapa sawit, aksesi, keragaman genetik, marka SSR, uji kekerabatan.ABSTRACTSSR Marker Selection for Genetic Diversity Analysis of Oil Palm AccessionsGenetic diversity analysis of oil palm accessions facilitates parent selection in a breeding program. The use of SSR markers enhances the accuracy and speed of oil palm phylogenetic analysis. SSR is a superior PCR-based genetic marker compared to other developed markers (e.g. AFLP, RAPD, and RFLP) due to its multi allelic nature, codominant characteristic, well-distributed across the plant genome, its economic assays, and high ability in differentiating closely related plant genetic materials. The objectives of this study were to: (1) select the SSR markers appropriate for oil palm accession diversity analysis; (2) analyze the selected markers to be used in genetic relationship studies both in analyzing within- and among- oil palm accessions as well as inter oil palm species. A total of 39 SSR markers were initially used in this study. The appropriate SSR markers were selected based on their polymorphism level, banding pattern, allele frequency and size, together with their distributions across the oil palm genome. The selected markers were used in the phylogenetic analysis studies involving genetic materials within- and among-oil palm accessions. These included 10 individual plants of the C103-T accession (within accession study), 9 accessions of Eo and 7 accessions of Eg (for inter-oil palm accessions and inter species studies). Dendograms were constructed based on Unweighted Pair Group Method Arithmetic (UPGMA) using the Numerical Taxonomy and Multivariate Analysis System (NTSYS) software version 2.1-pc. Results showed that the 39 SSR markers showed polymorphism level of 75% (ranges from 32 to 92%), allele number of 5.97 (2-14), and allele size of 119-330 bp. Based on the observed polymorphism level, allele size and frequency, banding pattern, and their distributions across the oil palm genome, 20 SSR markers were selected to be studied further. The selected SSR markers were tested their robustness to be used in the phylogenetic analyses of individual plants within an accession, among accessions of a species (Eo or Eg) as well as the individuals among oil species Eo and Eg. Phylogenetic analysis of 20 SSR markers on 10 individual plant within a Cameroon originated accession C103-T resulted genetic diversity of 14.37-37.38%. Diversity level of 8 accessions within species Eo was 7-15%. Analysis of inter species diversity Eo and Eg demonstrated diversity level of 5-45%. The observation results indicated that the 20 SSR markers were robust enough to be used in phylogenetic studies of oil palm accessions. The results shown by this study would be very useful in handling the oil palm germplasm in the field and should facilitate parent selection in a breeding program

Abstract

Salah satu faktor yang mempengaruhi pertumbuhan tanaman kelapa adalah ketersediaan unsur hara didalam tanah. Untuk dapat mengetahui ketersediaan unsur hara lahan didaerah Gorontalo dan Banyuwangi maka dilakukan pengambilan sampel tanah di dua daerah tersebut. Tujuan dari penelitian adalah untuk memeberikan gambaran tentang ketersediaan unsur hara pada lahan komposiot didaerah Gorontalo dan Banyuwangi. Hasil penelitian menunjukkan bahwa di daerah Gorontalo kadar hara N, P dan K berada dibawah batas kritikal sehingga diperlukan penambahan unsur tersebut lewat tindakan pemupukan. Sedangkan di daerah Banyuwangi unsur N dan K berada dibawah batas kritikal sehingga perlu dilakukan penambahan unsur hara tersebut sedangkan unsur P pada umumnya ( 80%) berada diatas batas kritikal. Namun yang perlu diperhatikan pada kedua daerah tersebut adalah sistem irigasi dan drainase sehingga tidak mengganggu pertumbuhan tanaman.

Abstract

Indonesia has a tidal swampy area of about 33.4 million hectares, from which + 20 million hectares could be cultivated as a coconut plantation. If it is used optimally, the area could play an important role in supporting the national food security. Several technologies have been produced and applied, and the use of adaptive varieties in tidal land, can improve and enhance the productivity of the land. The availability of superior tall coconut varieties to meet the required coconut seeds for coconut development program is still limited. All of the coconut high yielding varieties launched by the Minister of Agriculture are suitable for dry land only, and not for tidal one. Sri Gemilang, a coconut variety grown in tidal land in Parit Sialang Krubuk, Hidayah Village, Pelangiran District, Indragiri Hilir, Riau Province was evaluated from 2012 to 2016. Observations showed that the production of frutis and copra were relatively stable, averaging above 3.0 tons of copra/ha/year. Sri Gemilang variety with a potential endosperm weight of about 518 g/nut was selected as palms for superior seed sources. Weight of nuts decreased to about 433 g/nut during observation in 2016, after long dry season. However, it was still higher than the control varieties, DTA (371 g/nut) and DMT (366 g/nut) grown on the same tidal land. If the weight of coconut meat is converted to the production of copra/ha, it can reach > 3.0 tons of copra/ha/year, while DTA and DMT grown on tidal land was only 1.6 tons and 1.56 tons of copra/ha/year, respectively. The low weight of endosperm of DTA and DMT is presumably because both varieties which typically grow well on dry land, less adaptable on tidal land. ABSTRAKIndonesia memiliki lahan rawa pasang surut 33,4 juta hektar, sekitar 20 juta hektar dapat diusahakan sebagai perkebunan kelapa. Jika dimanfaatkan secara optimal akan berperan penting dalam mendukung swasembada dan ketahanan pangan nasional. Beberapa teknologi telah dihasilkan dan diterapkan, penggunaan varietas adaptif di lahan pasang surut, dapat memperbaiki dan meningkatkan produktivitas lahan. Jenis kelapa Dalam unggul yang tersedia masih sangat terbatas sehingga belum dapat memenuhi kebutuhan benih untuk program pengembangan kelapa. Varietas unggul kelapa yang telah dilepas oleh Menteri Pertanian, semuanya memiliki habitat pada lahan kering, sedangkan habitat pada lahan pasang surut belum ada. Kelapa Dalam Sri Gemilang tumbuh di lahan pasang surut, yaitu di Parit Sialang Krubuk, Desa Hidayah, Kecamatan Pelangiran, Kabupaten Indragiri Hilir, Provinsi Riau. Hasil penelitian tahun 2012 hingga 2016, menunjukkan bahwa produksi buah kelapa dan kopra relatif stabil, yaitu rata-rata di atas 3,0 ton kopra/ha/tahun. Pada varietas kelapa Sri Gemilang dilakukan pemilihan Pohon Induk dengan potensi rata-rata berat daging buah 518 g/butir. Kemarau panjang pada tahun 2015 mengakibatkan berat daging buah turun pada tahun 2016, yaitu 433 g/butir, namun lebih tinggi dibandingkan kelapa DTA (371 g/butir) dan DMT (366 g/butir) sebagai varietas pembanding yang ditanam di lahan pasang surut. Jika berat daging buah kelapa dikonversi ke produksi kopra per hektar maka kelapa Dalam Sri Gemilang mencapai > 3,0 ton kopra/hektar/tahun, sedangkan kelapa DTA dan DMT yang ditanam di lahan pasang surut masing-masing 1,6 ton dan 1,56 ton kopra/hektar/tahun. Hal ini menunjukkan bahwa Kelapa DTA dan DMT yang biasanya tumbuh baik dan berproduksi tinggi pada lahan kering, kurang adaptif pada lahan pasang surut.

Abstract

The utilization of starch-base ingredients, such as sago starch for the manufacture of edible films, is still growing. The nature of the film produced from starch material is still not optimal, hence research is needed to improve its utilization. Starch composites with other ingredients, such as pectin, are expected to grow their properties. The study aimed to characterize the properties of edible film produced from molat sago starch-pectin composites, including thickness, tensile strength, elongation, solubility, transparency, and water vapor transmission rate. The study was conducted from July to August 2017 at Food Chemistry and Biochemistry Laboratory, Pattimura University, Ambon, and Food Engineering Laboratory, Gadjah Mada University, Yogyakarta. The design used was a non-factorial completely randomized design of the treatment of composite sago-pectin starch, with five levels of treatment (3: 0; 2.75:0.25; 2.5:0.5; 2.25:0.75 and 2:1 (g/g)). Based on the results of the analysis of diversity, the treatment of composite sago-pectin starch affects the changes in the mechanical, physical, and barrier characteristics of the edible film. Increasing the concentration of pectin (0-1%) in the film solution decreases the elongation of the film, but increases the properties of thickness, tensile strength, solubility, transparency, and the rate of water vapor transmission. The treatment of sago-pectin starch composites 2:1 can improve the physical and mechanical properties of edible films, although it has a high value of solubility and water vapor transmission rate.ABSTRAKPemanfaatan bahan dasar pati-patian, seperti pati sagu untuk pembuatan edible film masih terus berkembang. Sifat film yang dihasilkan dari bahan pati-patian masih belum optimal. Diperlukan penelitian untuk dapat meningkatkan pemanfaatannya. Komposit pati dengan bahan lainnya, seperti pektin diharapkan dapat meningkatkan sifat-sifatnya. Tujuan penelitian adalah mengkarakteristik sifat-sifat edible film yang dihasilkan dari komposit pati sagu molat-pektin, meliputi ketebalan, kuat tarik, elongasi, daya larut, transparansi dan laju transmisi uap air. Penelitian dilaksanakan pada bulan Juli sampai dengan Agustus 2017 di Laboratorium Kimia dan Biokimia Pangan, Universitas Pattimura, Ambon, dan Laboratorium Rekayasa Pangan, Universitas Gadjah Mada, Yogyakarta. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan adalah komposit pati sagu molat-pektin, dengan lima taraf perlakuan (3:0; 2,75:0,25; 2,5:0,5; 2,25:0,75 dan 2:1 (g/g)). Berdasarkan hasil analisis keragaman, perlakuan komposit pati sagu molat-pektin berpengaruh terhadap perubahan sifat-sifat mekanik, fisik dan barrier edible film. Meningkatnya konsentrasi pektin (0-1%) pada larutan film menurunkan elongasi film, tetapi meningkatkan sifat-sifat ketebalan, kuat tarik, daya larut, transparansi, dan laju transmisi uap airnya. Perlakuan komposit pati sagu molat-pektin 2:1 dapat memperbaiki sifat fisik dan mekanik edible film walaupun daya larut dan nilai laju transmisi uap airnya tinggi.
