Effects of Using Multiple LED Beams on Red Dragon Fruit (Hylocereus polyrhizus). Red dragon fruit plant (H. polyrhizus) is a tropical plant and is very adaptable to growing environments and weather changes such as sunlight, wind, and rainfall. Dragon fruit plants is a long day plants (plants that require long enough sun exposure), which means that to produce this plant requires at least 12 hours of radiation. Knowing this, there needs to be a solution so that production stability can be controlled, one of which is by modifying the environment. The purpose of this study was to determine the effect of several colors of LED light (Light Emitting Diode) at the initiation stage of dragon fruit flowers in an effort to increase production. This study used a randomized block design with four treatments and nine replications, while the treatment consisted of control plants, the administration of white LED lights, yellow LED lights and blue LED lights. Three variables were observed, namely the number of flower buds, the number of blooming flowers and the number of young fruits. The results showed that the use of yellow LED lights give the best light intensity when compared to other treatments so that the yellow LED light treatment gave the best results on each variable including 6.44 pieces for flower buds, 7.56 pieces for flowers blooms and 7.56 pieces for young fruit.

<p>Kenikir dapat dimanfaatkan sebagai sayuran dengan cara mengonsumsi pucuknya. Kenikir banyak dijumpai sebagai tumbuhan liar sehingga diperlukan upaya untuk meningkatkan produksi pucuk kenikir. Produksi pucuk kenikir dapat dioptimalkan dengan melakukan perbaikan teknik budidaya, salah satunya pengaturan komposisi media tanam dan interval panen pucuk. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh komposisi media tanam dan interval pemanenan terhadap pertumbuhan dan produksi pucuk kenikir. Penelitian dilaksanakan pada bulan Februari sampai dengan Mei 2019 di Kebun Percobaan Fakultas Pertanian UGJ, Cirebon. Percobaan dilakukan dalam dua tahap, yaitu pengaruh komposisi media tanam terhadap pertumbuhan dan produksi pucuk kenikir pada panen pertama serta pengaruh interaksi antara komposisi media tanam dan interval pemanenan terhadap produksi pucuk pada panen kedua. Rancangan percobaan pada percobaan pertama menggunakan Rancangan Acak Kelompok (RAK) satu faktor, yaitu komposisi media tanam dengan sembilan ulangan dan rancangan percobaan pada percobaan kedua menggunakan RAK faktorial dua faktor. Faktor pertama adalah komposisi media tanam dan faktor kedua adalah interval pemanenan dan diulang sebanyak tiga kali. Komposisi media tanam terdiri atas tanah, tanah : pukan (2:1), dan tanah : pukan (1:1). Interval pemanenan yang dicobakan terdiri atas tiga taraf, yaitu 10, 15, dan 20 hari. Hasil penelitian menunjukkan bahwa media tanam tanah : pukan (1:1) meningkatkan pertumbuhan dan produksi pucuk kenikir baik pada saat panen pertama maupun panen kedua. Interval pemanenan 20 hari menurunkan produksi pucuk total disebabkan interval pemanenan yang terlalu lama menyebabkan banyaknya pucuk kenikir yang berbunga sehingga menjadi tidak layak untuk dipanen.</p><p><strong>Keywords</strong></p><p>Interval pemanenan; Kenikir (Cosmos caudatus); Media tanam; Pertumbuhan; Produksi pucuk</p><p><strong>Abstract</strong></p><p>Cosmos caudatus can be used as vegetable by its shoots. Cosmos are found as wild plant so that efforts are needed to increase shoot production. Shoot production can be optimized by media composition and harvesting interval. This research objective was to investigate planting media composition and harvesting interval effect on growth and shoot production of cosmos. The research was carried out for three months at Cirebon. The experiment was carried out in two stages: (1) the effect of media composition on growth and shoot at the first harvest and (2) the effect of interaction between media composition and shoot harvesting interval at the second harvest. The experimental design for first experiment used Randomized Block Design (RBD), namely the composition of media of soil, 2:1 soil-manure and 1:1 soil-manure with nine replications. Meanwhile, we used two factor factorial RBD for second experiment. The first factor was the media composition and the second factor was three harvest interval with three replications. The result showed that planting media of soil and manure (1:1) increased the growth and shoot both in the first and second harvesting. The harvesting interval of 20 days decrease the total shoot because many branches to flower so they cannot be harvested.</p>

Tacca (Tacca leontopetaloides (Linn.) O. Kuntze) is a tropical plant that is widely used for its starch in some countries as well as a medicinal plant. Tacca has advantages as it can grow on sand in tropical seashore areas and rain forests. Farmers in Madura Island Indonesia cultivated tacca by using mother tubers as propagules and harvest the daughter tubers, but no studies have been conducted on the growth of mini tubers and their cultivation. The purpose of this study was to find the best combination of planting media and the size of mini tuber for growing tacca. The experiment was set in a completely randomized block design with two factors and three replications. The planting media are sand : rice-hull charcoal : cow manure (1:1:1 v/v), soil : sand : cow manure (1:1:1 v/v), soil : rice-hull charcoal : cow manure (1:1:1 v/v), and soil : cow manure (1:1 v/v);mini-tuber weight are1-5 and  5.1-20 g. The result showed that Polynesian arrowroot grow best on sand : rice-hull charcoal : cow manure (1:1:1 v/v) and rice-hull charcoal : cow manure (1:1 v/v) media. Both propagules sizes can be used, but plants from large mini-tuber had better growth and produced larger mother and daughter tubers. Key words: mini tuber, parent tuber, Polynesian arrowroot, organic media planting, secondary tuber
