Abstract

Untuk mendukung pengembangan suatu komoditas, diperlukan varietas-varietas unggul berdaya hasil tinggi. Kegiatan penelitian uji daya hasil aksesi-aksesi plasma nutfah rosela herbal telah dilakukan di Muktiharjo, Kabupaten Pati mulai bulan Januari–Juni 2011. Tujuan penelitian ini adalah mendapatkan beberapa aksesi unggul yang berpotensi tinggi di lahan kering. Sebanyak 25 aksesi plasma nutfah diuji daya hasilnya dengan rancangan acak kelompok (RAK) diulang dua kali. Benih ditanam dengan jarak tanam 100 cm x 50 cm pada plot berukuran 10 m x 5 m. Pemupukan dan pemeliharaan lainnya sesuai dengan standar budi daya untuk tanaman rosela herbal. Parameter pengamatan terdiri atas: jumlah kapsul per tanaman, bobot 100 kelopak kering, produksi kapsul segar, produksi kelopak segar, dan produksi kelopak kering per hektar. Hasil penelitian menunjukkan bahwa produktivitas tertinggi dicapai oleh delapan aksesi yaitu 677, 675, 679, 681, 682, 684, 689, dan 671, dengan produksi kelopak kering masing-masing sebesar: 676,0; 605,5; 540,0; 463,5; 427,5; 385,5; 420,0; dan 414,0 kg/ha. Ada korelasi positif yang sangat nyata pada karakter jumlah kapsul per tanaman dengan produksi kapsul per hektar, produksi kelopak segar per hektar dan produksi kelopak kering per hektar dengan nilai korelasi masing-masing sebesar 0,725; 0,617; dan 0,584. Korelasi yang sangat nyata juga terdapat pada karakter produksi kapsul dengan produksi kelopak segar dan kelopak kering, karakter produksi kelopak segar dengan produksi kelopak kering per ha, serta bobot 100 kelopak kering dengan produksi kelopak kering per ha dengan nilai korelasi masing-masing: 0,978; 0,907; 0,939; dan 0,502.To support herbal roselle development in the future, the availability of new high-yield varieties were required. Screening of 25 herbal roselle accessions have been carried out on dry land Muktiharjo, Pati District started in January–June 2011. The purpose of this study was to obtain some superior high-potential accessions suitable for dry land. The screening used a randomized block design (RBD) with two replicates. Seeds were planted with a spacing of 100 cm x 50 cm on a plot measuring 10 m x 5 m. Fertilizing and other maintenance in accordance with the standards for the cultivation of herbal roselle plant. Parameter observed consist of number of capsules per plant, weight of 100 dry petals, fresh capsule production, fresh petals production, and dried petals production per hectare. The results showed that eight accessions consistently showed productivity of dried roselle calyx higher than two varieties used as a control. Those accessions were no: 677, 679, 675, 681, 682, 684, 689, and 671, with the production of dried petals ranged between 385–676 kg/ha. There is a positive correlation between the number of capsules per plant with a production of capsules per hectare, production per hectare of fresh petals and dried petals, production per hectare with a correlation value 0.725, 0.617, and 0.584, respectively. A significant correlation was also found in the character of capsule production with the production of fresh petals and dried petals, the fresh petals production with the production of dried petals per hectare, and weights of 100 petals dried with dried petals production per hectare by correlation values: 0.978, 0.907, 0.939, and 0.502, respectively

Abstract

ABSTRAKAbaka (Musa textilis Nee.) adalah tanaman sejenis pisang yang menghasilkan serat bernilai ekonomis tinggi. Kabupaten Kepulauan Talaud merupakan wilayah pengembangan abaka di Indonesia dengan sumber daya genetik abaka yang luas, sehingga perlu dilakukan observasi dengan tujuan untuk mengevaluasi potensi hasil dan mutu serat genotipe abaka yang potensial dikembangkan sebagai varietas unggul lokal. Observasi dilakukan di lahan petani, meliputi tiga Kecamatan: Esang, Beo Utara dan Rainis yang terletak di Pulau Karakelang, Kabupaten Kepulauan Talaud pada 2017 – 2019. Pengambilan contoh tanaman dilakukan pada populasi pertanaman di tiga wilayah dengan kondisi agroklimat berbeda. Untuk masing-masing klon pada setiap wilayah diamati 10 rumpun tanaman.  Pengamatan dilakukan saat panen, mulai panen pertama hingga keempat selama dua tahun yaitu pada karakter panjang batang, lingkar batang, bobot segar batang, bobot serat kering, rendemen dan mutu serat. Hasil observasi diperoleh empat klon unggul abaka yang memiliki potensi pertumbuhan dan produksi serat tinggi. Keempat klon tersebut adalah Rote EH, Rote EMT, Rote EM dan Rote BHJ, masing-masing dengan produktivitas dan kekuatan serat secara berurutan (6,24 ton/ha/tahun dan 32,69 g/tex), (5,91 ton/ha/tahun dan 28,25 g/tex), (5,66 ton/ha/tahun dan 38,96 g/tex), dan (4,37 ton/ha/tahun dan 24,18 g/tex). Klon-klon tersebut berpotensi sebagai varietas unggul abaka dan menjadi asset daerah dalam meningkatkan kesejahteraan masyarakat melalui pengembangan abaka.  ABSTRACTSuperior Abaka Local Clones in Talaud Islands Regency  Abaka (Musa textilis Nee.) produces high economic value of natural fiber. Talaud island District is one region in Indonesia that has developed abaca.  This region also has enormous abaca genetic resources. Therefore, it is required to evaluate the yield potential and fiber quality of the abaca genotypes that has the potential to be developed as a superior variety in supporting abaca development .Observations were carried out on farmers' plantation in three sub-districts: Esang, Beo Utara and Rainis on Karakelang Island, Talaud Islands, in 2017 – 2019. Samplings of observational plants were carried out on abaca populations in three different agro-climatic areas. In each region, 10 clumps of the same morphological characters of abaca plant were observed. Observations were made at harvest time, four times during two years. Observations consisted of: stem length, stem circumference, stem fresh weight, dry fiber weight, and fiber quality. Out of 25 clones observed, four superior abaka clones had very high growth potential and fiber production, namely Rote EMT, Rote EH, Rote EM and Rote BHJ. The potential fibre production and quality for each clone are Rote EH 6.24 tons/ha/yr, Rote EMT 5.91 tons/ha/yr, Rote EM 5.66 tons/ha/yr and Rote BHJ 4.37 tons/ha/yr. These clones have the potential to become superior varieties of abaca and become regional assets in improving community welfare through the development of abaca plantation.

Abstract

More than 40% of the potential gap of varieties of sugarcane with actual results in the field is one of the causes of sugar self-sufficiency in Indonesia which has not been reached. The limited knowledge about the responsiveness of  early maturity sugarcane varieties to ferlization is one of the factors causing the large gap. The study aims to determine the responsiveness of new superior early maturity sugarcane varieties conducted in Janti Village, Kediri during July 2018 – August 2019. The study was arranged in a split plot design and repeated 3 times. The main plot consists of 5 fertilizing doses (0.9; 1.0; 1.1; 1.2, and 1.3 times the recommended dose). The subplots consists of 6 new varieties of early maturity sugarcane (MLG 5, MLG 9, MLG 14, PSMLG 2, PSMLG 1, and PS 881). Regression analysis is used to determine the form of response. The optimum dose was determined using the first derivative for closed quadratic equations and was determined > 1.3 times for positive linear equations. Varieties were grouped based on their optimum dose into five groups (no response, little response, sufficient response, more response, and very responsive). The results showed that the MLG 5, PSMLG 1, and PS 881 were classified as sufficient response, while MLG 9, MLG 14, and PSMLG 2 were classified as very responsive to fertilization.
