In Vitro Planlet Induction of Tropical Pitcher Plant (Nepenthes Ampullaria Jack) by Various Thiamin and Benzyl Amino Purine Concentrate

Nepenthes is one of Indonesian tropical plant as a biodiversity source that endangered from its extinction. One of the effort to prevent its extinction by using plant tissue isolation method on Nepenthes multiplication are needed. This research was aimed to determine the best interaction between Thiamin and benzyl amino purine concentration on in vitro Nepenthes planlet growth, Thiamin best concentration on in vitro Nepenthes planlet growth, and benzyl amino purine best concentration on in vitro Nepenthes planlet growth. The research was conducted in Agriculture Department Biotechnology Laboratory Universitas Pembangunan Nasional “Veteran” Yogyakarta on January – April 2018. Completed Random Design method with 2 factors was used in this research. The first factor was various concentration of Thiamin with 8 ppm, 10 ppm, and 12 ppm. The second factors was various concentration of benzyl amino purine with 0,5 ppm, 1 ppm, and 1,5 ppm. Every combination was repeated 3 times. The result of this research showed that no interaction was found in every Thiamin and benzyl amino purine various concentration on in vitro Nepenthes planlet. The usage of 10 ppm Thiamin concentration (T2) produce the best results on sprout's amount and sprout's height. On 1 ppm of benzyl amino purine concentration produce the best result on sprout's amount, sptout's height, and amount of leaves

The Improvement of Agronomic Traits of Chrysanthemum Through Additional Lighting and Flower Faselife Assessment in Hargobinangun, Sleman, DIY

Chrysanthemum cultivation in medium height plains is still facing obstacles where the agronomic properties are not as good as in the highlands. It is important to find cultivation techniques that can improve agronomic properties of chrysanthemum. The setting of additional lighting technique remains to be learned then applied at planting chrysanthemum plain medium. The research purpose is to determine the best additional length of radiation for the improvement of agronomic properties of chrysanthemum. In addition to determining the best chrysanthemum varieties to be developed in the medium height plain as Hargobinangun. The research has been conducted in Hargobinangun, Sleman in April-August 2011 in two stages. The first stage is to determine the length of the addition of irradiation to improve the agronomic properties of chrysanthemum, namely 2,3,4 and 5 hours in the evening starting at 22:00 pm. While the second stage is to look at various kinds of flower Faselife varieties, namely Sakuntala, Snow white, Wastu kania, Shamrock, Puspita Nusantara, Padmabuana and Tirta ayuni. The results was showing that cultivation techniques with the addition of irradiation for 5 hours will improve agronomic traits such as chrysanthemum plant height, stem diameter, flower diameter, flower number and brightness of flower color ribbon. While the flower varieties that have good prospects to be developed in the plain medium Hargobinangun because it has a much longer period of flower freshness is Puspita Nusantara, Sakuntala and Snow White

Pengaruh Pupuk Kandang dan Konsentrasi Urine Kelinci terhadap Pertumbuhan dan Hasil Tanaman Mentimun (Cucumis Sativus L.)

Kondisi lahan pertanian di Indonesia semakin mengalami kerusakan, salah satunya diakibatkan oleh perilaku petani yang lebih menggunakan pupuk anorganik dibandingkan pupuk organik. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan serta hasil berbagai macam pupuk kandang dan konsentrasi urine kelinci terhadap tanaman mentimun. Penelitian ini dilaksanakan pada Januari - Maret 2021 di Desa Wanantara, Kecamatan Sindang, Kabupaten Indramayu. Penelitian ini menggunakan percobaan faktorial, dirancang menggunakan Rancangan Acak Kelompok Lengkap (RAKL) 2 faktor yang diulang sebanyak 3 kali. Faktor pertama, macam pupuk kandang yang terdiri atas 3 taraf yaitu pupuk kandang sapi, pupuk kandang kambing, pupuk kandang ayam. Faktor kedua, konsentrasi urin kelinci yang terdiri atas 4 taraf yaitu 0 ml/l, 100ml/l, 200ml/l, 300ml/l. Data dianalisis menggunakan analisis sidik ragam (Anova) dengan taraf 5%. Uji lanjut perlakuan dilanjutkan dengan DMRT taraf 5%. Hasil percobaan menunjukkan adanya interaksi pada parameter panjang sulur 1 MST rerata 10,89 cm dan 2 MST rerata 28,66cm. Perlakuan pupuk kandang ayam memberikan hasil yang berbeda nyata terhadap panjang sulur 3,4 MST rerata 72,24cm; 83,25cm, diameter batang 1,2,3,4 MST rerata 3,96mm; 6,32mm; 8,14mm; 8,61mm, jumlah daun 1,2,3,4 MST rerata 5,19 helai; 7,22 helai; 12,06 helai; 12,30 helai, jumlah bunga rerata 4,50 buah, panjang buah rerata 12,56 cm, bobot buah per buah rerata 128,57 gram, bobot buah per tanaman rerata 1324,33 gram, bobot segar tanaman rerata 49,92 gram, dan bobot kering tanaman rerata 22,17 gram. Perlakuan 300 ml/liter memberikan hasil berbeda nyata terhadap diameter batang 1 MST rerata 3,84mm dan bobot buah per tanaman rerata 1197,67 dengan produksi mencapai 1104,61 gram/polybag atau 60,8 ton/ha

Growth and Brix of Sweet Sorghum Under Different Fertilizer Application in Maginal Land

Sorghum is one of the commodities that are potentially very good to meet the needs of food, feed, industrial and renewable energy sources. Sorghum has protein, iron and calcium content that is much higher than rice. Additionally, sorghum has wide adaptability and is a plant that is tolerant to drought and low fertility. Therefore it can be cultivated on marginal lands. This study aimed to study the effects of fertilization on the growth and brix value of sweet sorghum cultivated on marginal land. The experiment was arranged in randomized completely block design, with three treatments, namely NPK, NPK + LOF (Liquid Organic Fertilizer) / 1 week, NPK + LOF/ 2 weeks. Each treatment consisted of 5 replication, and for each replication 6 plant samples was observed. Each plot consisted of 12 rows and in each row there were 7 plants. Sorghum was planted with the distance between rows 75 cm and the distance between plants in rows was 30 cm. The data was subjected to analysis of variance followed by Duncan's Multiple Range Test. The application of NPK fertilizer plus LOF once a week resulted in significantly higher plant height, number of leaves and brix value compared to NPK fertilizer plus LOF fortnightly or just NPK fertilizer alone. Fertilization treatment did not significantly affect sorghum stem diameter, except at the age of 3 weeks after planting
