Abstract

The objectives of this research was to study the effect of shade on growth and productivity of several  indigenous vegetables.  The research was conducted at Vegetable Garden, University Farm IPB, Darmaga from February until June 2009. This research was arranged in a Randomized Completely Block Design, 1 factor with 2 treatments, shading (N1) and no shading (N0). Result of the research showed that shading increased plant height, length of branch, leaf length and width of Daun Ginseng (Talinum triangulare); leaf diameter, leaf length and width, petiole length of Sambung Nyawa (Gynura procumbens); leaf length and width of Katuk (Sauropus androgynus); leaf number of Kenikir (Cosmos caudatus), stem diameter of Kemangi (Ocimum americanum); plant height, length of branch, number of branch, leaf length and width of Pohpohan (Pilea trinervia). Shading also increased total fresh and dry weight/plant of Daun Ginseng; and total fresh/plant of Sambung Nyawa and Pohpohan plants. Productivity of Daun Ginseng and Pohpohan at shade field was better than at open field. Daun Ginseng, Sambung Nyawa, Kenikir, Kemangi and Pohpohan plants prefered growing at low light intensity (shade plants).   Key words: indigenous vegetable, shading, growth, productivity

Abstract

ABSTRACTBangun-bangun [Plectranthus amboinicus] is a functional vegetable that is used as lactagogue. This research was aimed to provide information of the effect of organic fertilizer on shoot, total phenolic, and anthocyanin production of bangun-bangun. This experiment was conducted at Bogor Agricultural University, Leuwikopo experimental station (Indonesia), from December 2012 to February 2013. The experiment was laid out in randomized block design with single factor with five combination of organic fertilizer treatments (combination of cow manure 12.3 t ha-1, rock phosphate 1.5 t ha-1, rice-hull ash 5.5 t ha-1) with three replications. The result showed that application of organic fertilizer increased of shoot production. Application of 12.3 t ha-1 cow manure + 1.5 t ha-1 rock phosphate + 5.5 t ha-1 rice-hull ash produced shoot dry weight ha-1 (57.33%) and metabolite production ha-1 (total phenolic 12.06%, anthocyanin 41.73%) higher than no fertilizing (P > 0.05). Application of cow manure + rock phosphate produced the lowest shoot dry weight ha-1 and metabolite production ha-1. The result of this research suggested that nitrogen, phosphorus, and potassium were needed on shoot production of bangun-bangun.Key words: Plectranthus amboinicus, phenylalanine ammonia lyase, secondary metabolite

Abstract

Intensitas cahaya rendah merupakan salah satu faktor eksternal lingkungan yang dapat mempengaruhi pertumbuhan suatu tanaman. Intensitas cahaya yang optimal dapat meningkatkan pertumbuhan tanaman. Kolesom merupakan salah satu jenis sayuran fungsional yang dapat digunakan sebagai tanaman obat. Penelitian ini bertujuan untuk mempelajari pengaruh intensitas cahaya rendah terhadap pertumbuhan dan hasil pucuk kolesom. Percobaan ini dilakukan di Politeknik Lembaga Pendidikan Perkebunan (LPP) Yogyakarta, dari bulan Maret hingga September 2016. Penelitian ini menggunakan rancangan acak kelompok faktor tunggal dengan 2 taraf perlakuan, yaitu tanpa naungan (N0) dan naungan (N1). Setiap perlakuan diulang tiga kali sehingga terdapat 6 satuan percobaan. Hasil percobaan menunjuk-kan bahwa intensitas cahaya rendah (naungan paranet 82.51%) dapat menekan pertumbuhan dan hasil pucuk kolesom. Naungan menurunkan tinggi tanaman dan jumlah cabang kolesom. Daun kolesom yang ternaungi lebih lebar jika dibandingkan tanpa naungan. Naungan menurunkan jumlah pucuk, bobot basah dan kering biomassa, tetapi meningkatkan bobot per pucuk kolesom. Kata kunci: biomassa, laju tumbuh relatif, naungan, Talinum triangulare

Abstract

Sari. Pupuk organik bermanfaat untuk meningkatkan kandungan hara, bahan organik tanah, serta memperbaiki sifat fisik, kimia, dan biologi tanah. Vinasse merupakan limbah dari proses pembuatan bioetanol pada industri pengolahan gula, jika telah mengalami proses pengomposan dapat digunakan sebagai pupuk organik cair (POC) vinasse yang dapat meningkatkan pertumbuhan tanaman. Bawang dayak merupakan salah satu tanaman hortikultura yang dapat dijadikan sebagai tanaman berkhasiat obat. Penelitian ini bertujuan untuk mempelajari pengaruh cara pemberian pupuk organik cair vinasse terhadap pertumbuhan awal tanaman bawang dayak. Percobaan ini dilakukan di Politeknik Lembaga Pendidikan Perkebunan (LPP) Yogyakarta, dari bulan Juli hingga November 2018. Penelitian ini menggunakan rancangan acak kelompok sederhana dengan empat perlakuan, yaitu tanpa pupuk cair, pupuk organik cair pembanding melalui daun, pupuk cair vinasse melalui daun, dan pupuk cair vinasse melalui tanah. Setiap perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa cara pemberian pupuk organik cair vinasse tidak berpengaruh terhadap pertumbuhan tanaman bawang dayak (tinggi tanaman maupun jumlah daun) hingga umur tanaman 6,7 dan 8 MST).Kata kunci: bawang dayak, cara aplikasi, pupuk cair, vinasseAbstract. Organic fertilizer can be used to increase nutrient content and soil organic matter. Vinasse is one of sugarcane processing liquid waste. Vinasse can be used as liquid organic fertilizer by composting process and can influence of the plant growth. Eleutherine palmifolia is a functional vegetable that can used as medicinal plant for cancer diseases. This research was aimed to provide information about the effect of organic fertilizer from vinasse waste on the early growth of Eleutherine palmifolia. This experiment was conducted at Politeknik LPP Yogyakarta, from July to November 2018. It used randomized block design with single factor with four treatments (without organic fertilizer; commercial liquid organic fertilizer; vinasse by foliar application; and vinasse by soil application). Each treatment was repeated three times. The result showed that application method of vinasse liquid organic fertilizer was not affected on early growth of Eleutherine palmifolia (plant height and number of leaf) at 6, 7 and 8 weeks after planting.Keywords: application method, Eleutherine palmifolia, liquid fertilizer, vinasse

Abstract

ABSTRACTWaterleaf (Talinum triangulare (Jacq.)Willd) is one of functional vegetable. T. triangulare contains flavonoid and anthocyanin that have function as antioxidant and cardioprotective. This research was aimed to study and provide information about the effect of shading stress on shoot production and flavonoid content of T. triangulare shoot. This experiment was conducted at Teaching Farm Polytechnic of LPP Yogyakarta, from March until September 2016. The experiment was laid out in randomized block design with single factor. There were two treatments that used in thisexperiment (without shading and shading). Each treatment was repeated three times. The result showed that shading 82.51% decrease shoot production of T. triangulare. Shading gave b chlorophyll content and chlorophyll b/a ratio higher than without shading. Shading increase flavonoid total content.Keywords: anthocyanin, fenilpropanoid, low light intensity, secondary metabolite, TalinumtriangulareABSTRAKKolesom (Talinum triangulare (Jacq.) Willd.) merupakan salah satu jenis sayuran fungsional. Tanaman kolesom megandung senyawa flavonoid dan antosianin yang berperan sebagai antioksidan dan cardioprotective. Penelitian ini bertujuan untuk menerangkan respon produksi pucuk dankandungan flavonoid tanaman kolesom pada pemberian naungan. Percobaan ini dilakukan di Politeknik LPP Yogyakarta, dari bulan Maret sampai September 2016. Percobaan ini menggunakan rancangan acak kelompok faktor tunggal yang terdiri dari dua taraf perlakuan, yaitu tanpa naungan dan naungan paranet. Setiap perlakuan diulang tiga kali sehingga total terdapat enam satuan percobaan. Pemberian naungan paranet 82.51% menurunkan produksi pucuk kolesom. Kandungan klorofil b dan nisbah klorofil b/a pucuk kolesom yang ternaungi lebih tinggi dibandingkan dengan tanpa naungan. Naungan meningkatkan kandungan total flavonoid.Kata kunci: antosianin, fenilpropanoid, intensitas cahaya rendah, metabolit sekunder, Talinum triangulare
