Abstract

Konservasi tanaman krisan diperlukan agar sumber daya genetik krisan tetap terjaga kelestariannya. Salah satu upaya konservasi yang banyak diteliti akhir-akhir ini adalah konservasi dengan metode enkapsulasi. Tujuan penelitian untuk mendapatkan komposisi pembuatan kapsul untuk enkapsulasi pada tanaman krisan dan mendapatkan teknik konservasi tanaman krisan dengan menggunakan penggabungan metode enkapsulasi dan zat retardan. Penelitian dilaksanakan di laboratorium konservasi Balai Penelitian Tanaman Hias dari bulan Januari - Desember 2020. Penelitian menggunakan Krisan varietas Alisha dan Xavhia. Penelitian terdiri atas dua unit kegiatan. Kegiatan pertama bertujuan melihat pengaruh komposisi pembuatan kapsul dan sumber eksplan terhadap keberhasilan enkapsulasi pada tanaman krisan. Kegiatan kedua bertujuan untuk melihat pengaruh penambahan retardan pada media enkapsulasi terhadap penyimpanan eksplan krisan. Penelitian disusun menggunakan Rancangan Acak Lengkap. Kegiatan pertama terdiri atas perlakuan kombinasi antara komposisi media dan bagian tanaman yang dijadikan sumber eksplan. Kegiatan kedua berupa penambahan retardan manitol dan paclobutrazol ke dalam matriks kapsul. Hasil penelitian menunjukkan bahwa matriks kapsul dengan komposisi 3% Alginat dalam media ½ MS lebih baik secara nyata sebagai media penyimpanan materi eksplan dibandingkan 3% Alginat dalam aquadesh. Berdasarkan respon waktu pertumbuhan, sebagai sumber eksplan pada kegiatan konservasi materi yang berasal dari ruas batang lebih baik dibandingkan dari tunas pucuk. Penambahan retardan mannitol 1,5% dan paclobutarzol 2 ppm belum dapat menekan pertumbuhan eksplan dalam matriks kapsul. Pada varietas Alisha, penambahan retardan manitol 1,5% dapat mempertahankan kesegaran dan daya regenerasi eksplan hingga 7 bulan. Penelitian ini memberikan informasi awal untuk kegiatan konservasi krisan dengan teknik enkapsulasi krisan yang digabungkan dengan penambahan retardan mannitol dan paclobutrazol.KeywordsKonservasi in vitro; Chrysanthemums; EnkapsulasiAbstractChrysanthemum plant conservation is needed to maintain genetic resources preservation of chrysanthemum. One of the conservation efforts that has been widely researched recently is conservation using the encapsulation method. The aim of the study was to obtain the composition of capsules for encapsulation in chrysanthemum plants and to obtain chrysanthemum conservation techniques using a combination of encapsulation methods and retardant substances. The research was carried out in the Conservation Laboratory of the Ornamental Plants Research Institute from January to December 2020. The research material used Alisha and Xavhia chrysanthemum varieties. The research consisted of two activity units. The first activity aimed to see the effect of the composition of capsules and explant sources on the success of encapsulation in chrysanthemum plants. The second activity aimed to see the effect of retardant added to the encapsulation media on the preservation of chrysanthemum explants. The study used a Completely Randomized Design. The first activity consisted of a combination treatment between the composition of the media and the plant parts used as a source of explants. The second activity was the addition of retardant mannitol and paclobutrazol into the capsule matrix. The results showed that the capsule matrix with a composition of 3% Alginate in ½ MS media was significantly better as a storage medium for explants than 3% Alginate in aquadesh. Based on the response of growth time, as a source of explants in conservation activities, material derived from stem segments is better than shoots. The addition of retardant mannitol 1.5% and paclobutarzol 2 ppm could not suppress the growth of explants in the capsule matrix. In Alisha variety, the addition of 1.5% mannitol retardant was able to maintain the freshness and regeneration of explants for up to 7 months. This study provides preliminary information for chrysanthemum conservation activities with chrysanthemum encapsulation technique combined with the addition of the retardant mannitol and paclobutrazole.

Abstract

Perkembangan pasar bebas berdampak terhadap selera produk-produk pertanian, seperti warna buah mangga. Antosianin merupakan senyawa yang bertanggung jawab dalam menginduksi warna pada buah. Senyawa ini diregulasi oleh gen faktor transkripsi MYB. Mutasi Single Nucleotide Polymorphism (SNP) daerah ekson gen MYB dapat mengubah asam amino yang memengaruhi aktivitas enzim yang mengakibatkan munculnya variasi fenotipe warna buah di antara individu-individu dalam spesies yang sama. Penelitian ini bertujuan menemukan SNP pada gen MYB dari kulit buah mangga varietas Arum Manis, Gedong Gincu, Manalagi, Golek, dan Cengkir. Penelitian dilakukan dengan tiga tahap utama, yaitu isolasi DNA kulit buah mangga, Polymerase Chain Reaction (PCR), dan proses sekuensing oleh Macrogen Inc. (Singapore). Hasil multiple sequence alignment asam amino gen faktor transkripsi MYB menunjukkan adanya perbedaan basa yang mengakibatkan munculnya stop codon dari SNP 337 A→T dan SNP 338 A→G yang memengaruhi fenotipe warna kulit buah. SNP yang memunculkan stop codon dapat direkomendasikan untuk membedakan fenotipe pigmentasi antosianin pada kulit buah mangga Gedong Gincu yang bewarna merah dengan warna kulit buah mangga yang lainnya. Adanya SNP menyebabkan prematur stop codon yang terjadi pada gen faktor transkripsi MYB dan diduga berpengaruh terhadap pigmentasi antosianin.KeywordsMangga; SNP; Faktor transkripsi; Antosianin; MYBAbstract The development of free markets gives an impact on appetite for agricultural products, such as the color of mangoes fruit skin. Anthocyanins are compounds that are responsible for giving color to the fruit skin, these compounds are regulated by the MYB transcription factor genes. Single Nucleotide Polymorphism (SNP) mutations in the exon region of the MYB gene can change amino acids that affect enzyme activity, resulting in phenotypic variations in fruit color among individuals in the same species. This study aims to find SNP in MYB genes from mango peel varieties Arum Manis, Gedong Gincu, Manalagi, Golek, and Cengkir. The research was conducted in three main stages, namely isolation of mango peel DNA, Polymerase Chain Reaction (PCR), and sequencing process by Macrogen Inc (Singapore). The results of multiple sequence alignment of the amino acid MYB transcription factor genes showed a base difference which resulted in the appearance of a stop codon from SNP 337 A→T and SNP 338 A→G which affected the phenotype of fruit skin color. The SNP that raises the stop codon can be recommended to differentiate the anthocyanin pigmentation phenotype on the red skin of the mango Gedong Gincu from the skin color of other mangoes. The presence of SNP causes premature stop codon that occurs in the MYB transcription factor gene and is thought to have an effect on anthocyanin pigmentation.

[The Effect of Habitat and Pest Control Methods on the Population and Intensity of Attacks of Citrus Rust Mite (Phyllocoptruta oleivora)]Habitat di sekitar lahan dan cara pengendalian hama dapat berpengaruh terhadap populasi dan intensitas serangan hama tungau karat jeruk Phyllopcoptruta oleivora (Ashmead). Tujuan penelitian adalah mempelajari kepadatan populasi dan intensitas serangan hama tungau karat jeruk pada kondisi habitat di sekitar lahan dan cara pengendalian hama tanaman jeruk berbeda. Penelitian dilakukan pada 16 lahan jeruk milik petani yang tersebar pada tiga Kecamatan di Kabupaten Malang, Jawa Timur. Di setiap lahan ditentukan plot pengamatan berukuran 1.200 m2 dan setiap plot dipilih 10 tanaman jeruk secara purposive sampling untuk diamati kepadatan populasi dan intensitas serangan hama. Hasil penelitian diperoleh kepadatan populasi dan intensitas serangan tungau P. oleivora yang berbeda pada kondisi habitat berbeda. Kepadatan populasi dan intensitas serangan hama tungau pada habitat sekitar kebun jeruk (7,53 ekor dan 8,76 % per buah) lebih rendah dibanding pada habitat lain. Kondisi habitat sekitar lahan dapat merespon kemampuan hama untuk mempertahankan hidup dan bereproduksi. Pengendalian hama berdasarkan monitoring memengaruhi kepadatan populasi dan intensitas serangan hama tungau karat jeruk (4,82 ekor dan 5,45 % per buah). Manajemen habitat sekitar lahan pertanian dan cara pengendalian hama merupakan hal yang penting untuk dilakukan sebagai upaya strategi preventif dalam pencegahan serangan hama tungau P. oleivora.KeywordsJeruk; Habitat; Monitoring; Phyllopcoptruta oleivoraAbstractHabitat of the land and pest control methods can affect the population and intensity of attack by the citrus rust mite Phyllopcoptruta oleivora (Ashmead). The purpose of the study was to study was to know the population density and intensity of citrus rust mite attacks in habitat conditions around the land and different methods of controlling citrus pests. The study was conducted on 16 citrus farms owned by farmers spread over three Subdistricts in Malang Regency, East Java. Each plot of land was determined with a size of 1,200 m2 and 10 citrus plants were selected by purposive sampling for each plot to observe population density and pest attack intensity. The results showed that the population density and intensity of attack of P. oleivora mites were different in different habitat conditions. Population density and intensity of mite infestation in habitats around citrus gardens (7.53 individuals and 8.76% per fruit) were lower than in other habitats. Habitat conditions around the land can respond to the ability of pests to survive and reproduce. Pest control based on monitoring affects population density and intensity of attack of citrus rust mites (4.82 individuals and 5.45% per fruit). Habitat management around agricultural land and pest control methods are important things to do as a preventive strategy in preventing P. oleivora mite attacks.

Abstract

[Effect of Rice Husk Biochar-Coated Urea Fertilizer on Growth and Yield of Garlic (Allium sativum L.) at Sembalun Higland, West Nusa Tenggara]Kebutuhan nasional bawang putih diperkirakan sebanyak 500.000 ton per tahun, dan hanya mampu dipenuhi oleh produksi dalam negeri sebesar 20.000 ton. Untuk itu diperlukan teknologi yang dapat meningkatkan produksi bawang putih, antara lain pemupukan. Selama ini budidaya bawang putih menggunakan pupuk sintetik, namun pemberian pupuk anorganik yang berlebihan dapat mengakibatkan produktivitas lahan menurun. Morfologi akar tanaman bawang putih yang serabut dan pendek dapat menyebabkan penyerapan pupuk yang memiliki tingkat mobilitas tinggi seperti urea tidak dapat termanfaatkan dengan maksimal sehingga diperlukan upaya untuk mengurangi kehilangan pupuk urea, antara lain dengan salut arang aktif. Kegiatan ini bertujuan untuk mengetahui efek aplikasi urea salut pada pertumbuhan dan hasil bawang putih. Urea yang dicampurkan dengan salut arang diaplikasikan pada 15 dan 35 hari setelah tanam. Kegiatan dilaksanakan pada musim kemarau/MK-I bulan April-September 2019 di dataran tinggi Sembalun, NTB. Penelitian menggunakan Rancangan Acak Kelompok (RAK) satu faktor, dengan tujuh taraf dosis pemupukan urea bersalut arang sekam padi (urea salut) dalam empat ulangan plot sehingga terdapat 28 plot percobaan. Berdasarkan hasil percobaan diketahui bahwa pemupukan urea salut 350 kg/ha memberikan hasil tertinggi dan pemupukan urea salut sebesar 200 kg/ha menghasilkan produksi setara dengan pupuk urea tanpa salut pada dosis 250 kg/ha. Hal ini menunjukkan terjadi peningkatan produksi seiring meningkatnya dosis pupuk urea dan salut arang aktif dapat mengefisiensikan penggunaan pupuk urea.KeywordsBawang putih; Urea salut; Dataran tinggi SembalunAbstractIndonesian demand for garlic is estimated at 500,000 tons per year, while the average national garlic production at 20,000 tons. For that it takes technology that can increase the production of garlic, amongst other fertilizer. All these years the garlic cultivation uses synthetic fertilizer. All these years the garlic cultivation uses synthetic fertilizer, excessive application of inorganic fertilizers could decrease land productivity. The root morphology of garlic which are fibrous and short causing less optimal absorption of some mobile nutrient such as nitrogen in urea, so it takes an effort to reduce loss to the urea fertilizer, amongst ither active charcoal coated This experiment aimed to find out effect of coated urea application to growth and yield of garlic. Urea was coated by mixing it with grounded and sifed rice husk biochar then applied at 15 and 35 days after planting. The experiment was carried from April to September 2019 at Sembalun Highland of Nusa Tenggara Barat (NTB) Province. The study used a randomized block design (RAK) with one factor, with seven levels of fertilizer doses of urea coated with rice husk charcoal (urea coated) in four replicate plots, so that there were 28 experimental plots Based on the experimental results, it was found that 350 kg/ha of urea-coated fertilizer gave the highest yield, and 200 kg/ha of urea-coated fertilizer produced equivalent production of uncoated urea at a dose of 250 kg/ha. This shows that there is an increase in production along with increasing doses of urea fertilizer and activated charcoal coated can make the use of urea fertilizer more efficient.
