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.

Abstract

ABSTRAK Program pemuliaan untuk peningkatan produksi minyak kelapa sawit dapat dilakukan dengan cara melakukan seleksi plasma nutfah, observasi/eksplorasi lapang, maupun introduksi aksesi baru dari luar negeri. Teknologi seleksi kelapa sawit dapat dilakukan secara konvensional dan non-konvensional. Penelitian ini bertujuan untuk memperoleh informasi keragaman genetik aksesi kelapa sawit asal Kamerun  berdasarkan keragaman karakter morfologi, produksi awal, dengan menggunakan marka molekuler  SSR. Penelitian dilakukan di KP Sitiung dan BB Biogen. Sampel yang dipilih adalah aksesi yang memiliki produksi awal tandan buah segar (TBS) minimal 4 kg.  Sebanyak 35 aksesi kelapa sawit asal Kamerun dan 20 primer SSR digunakan dalam penelitian ini. Hasil pengamatan karakter morfologi menunjukkan bahwa tidak terdapat perbedaan karakter morfologi diantara 35 tanaman kelapa sawit yang produksi awalnya ≥ 4 kg TBS. Produksi awal kelapa sawit berkisar antara 4 - 9,5 kg TBS per tandan dengan koefisien keragaman rendah, yaitu < 20%. Berdasarkan analisis 20 primer SSR dihasilkan   enam pita dengan kisaran 4−12 alel. Jumlah alel dominan sangat mendominasi dibanding dengan alel jarang maupun alel sedang.  Nilai Polymorphism Information Content (PIC) yang diperoleh sebagian bernilai negatif, 11 primer (55%) bernilai positif. Primer MEgcl3639 menghasilkan nilai PIC tertinggi (0,65), sedangkan nilai PIC terendah pada primer MEgcl0046 (-0,48). Berdasarkan analisis UPGMA aksesi 35 kelapa sawit terbagi  ke dalam dua kelompok, yaitu kelompok I terdiri dari 34 aksesi pada tingkat kesamaan genetik 42,5 - 67,5%, dan  kelompok II, yaitu satu aksesi (D91.4). Aksesi  D91.4 memiliki komposisi genetik yang sangat berbeda dengan kelompok I, dapat digunakan sebagai calon tetua persilangan. Perlu penelitian lebih detail pada aksesi D91.4 ini untuk pengamatan karakter kadar minyak, ketebalan cangkang, daging buah, dll.Kata kunci : Kelapa sawit, Kamerun, produksi awal, SSR. Diveristy Analysis of 35 Oil Palm Accessions (Elaeis guineensis Jacq.) Originated from Cameroon Based on Early Production Character by Using SSR Markers ABSTRACT Oil palm breeding programs to increase oil palm production can be done by under going selection in the germplasm collection, observation/exploration in the field and introduction from abroad. The technology can also be done by conventional or non-convention always. This study aimed to obtain information about genetic diversity of palm accessions originated from Cameroon based on the diversity of morphology and early production characters by using SSR molecular markers. Selected samples were those  that had early production of fresh fruit bunches (FFB) of at least 4 kg. The  research were held in Sitiung Field Station and ICABIOGRAD. Accessions used were oil palm accessions  originated from Cameroon as many as 35 accessions, where as microsatellite primers used were as many as 20 SSR  primers. The observation result of morphological characters showed that 35 oil palm accessions with production level of  ≥4,00 kg of FFB were not statically different. Initial production of oil palm accession were ranged from 4,00 to 9,50 kg  FFB per cluster with low diversity coefficient of <20%, which indicating high level of genetic uniformity. Molecular  analysis by using 20 SSR primers resulted  in number of bands up to six, with a range of 4-12 alleles. Dominant alleles  were more dominat as compared to rare or medium alleles. Some of Polymorphism Information Content (PIC) values were  obtained  negative, and only 11 primers (55%) showed positive PIC value. In this study, the primer Megcl3639 produced  the highest PIC value (0.65), while the lowest value was obtained on the primer MEgcl0046 (-0,48). Based on the UPGMA  analysis, 35 oil palm accessions were divided into two groups. The first group was comprised by 34 accessions with similarity of 42,5 - 67,5%, where as group II was comprised by one accession (D91.4). Accession D91.4 has a genetic composition that is very different the group I, can be used as a prospective parent for crosses. More detailed research is needed on this D91.4 accessions such as oil content, shell thickness, thickness of fruit, etc.Keywords: Oil palm, Cameroon, early production, SSR.
