Abstract

ABSTRACTWaterleaf shoot (Talinum triangulare (Jacq.) Willd) is consumed as vegetable that contains some metabolites. The purpose of this research was to investigate the effect of organic fertilizer on shoot production and its metabolites i.e. protein, vitamin C, flavonoid, and peroxidase enzyme (POD) activity at 10, 12, and 14 weeks after planting. This experiment was conducted at Leuwikopo Experimental Station, Bogor, Indonesia from November 2012-February 2013. The organic fertilizers applied were cow manure (CM) (12.3 ton ha-1), rock phosphate (RP) (1.5 ton ha-1), and rice-hull ash (RH) (5.5 ton ha-1). These organic fertilizers were combined into four treatments by using minus one test method and one control. Each treatment was repeated three times. The result showed that combination of organic fertilizer had the same effects on shoot production and metabolite content of waterleaf. It showed that the amount of organic fertilizers was not significantly sufficient to contribute nutrients to the plant. Keywords: flavonoid, POD activity, repeated harvesting, Talinum triangulare, vitamin C

Abstract

Rapid urban development demands a lot of infrastructure development. The development aims to support the activities of urban communities. Many research has been done on the structure, but the assessment of the visual quality of these structures is still very rarely done, especially in Indonesia. Flyovers are one of the structures that are often present in cities to solve congestion problems. Jakarta as the capital city, has many of these structures. Unfortunately, unwittingly adding structures can affect the visual quality of the surrounding environment. There are many ways to beautify these structures such as by adding plants, giving ornaments in the form of reliefs, to painting with mural art. The purpose of this article is to evaluate the visual quality of flyover structures. The methods used in this article include scenic beauty estimation (SBE), semantic differential (SD), factor analysis, multidimensional scaling, and Kendall’s W. The results obtained are different levels of visual quality of flyover structures based on the appearance of complementary ornaments. Based on SBE analysis, the structure with reliefs that were not colored showed poor visual quality with an SBE value of -46,483. High visual quality based on SBE analysis, namely the structure with the softscape element in the form of landscape plants (89,777). The impression caused by the structure with softscape elements in the form of landscape plants is considered shadier and attractive.

Abstract

Bantar Agung Village in Majalengka Regency, West Java Province, is developing agriculturally-based tourism. The Ciboer Rice Fields area is one of the attractions in the village of Bantar Agung that presents the visual beauty of the rice field landscape. New agrotourism opportunities will be developed in this area. The study has aimed to evaluate the visual quality of the Ciboer Rice Fields and how it would be affected by agrotourism-related changes. Data were analyzed using Kendall’s W test, scenic beauty estimation (SBE), semantic differential (SD), factor analysis, and multidimensional scaling (MDS). It is found that when more objects are added to the Ciboer Rice Fields landscape, the value of beauty is diminished. Village regulations are needed to protect the visual experience of the Ciboer Rice Fields.

Abstract

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.KeywordsInterval pemanenan; Kenikir (Cosmos caudatus); Media tanam; Pertumbuhan; Produksi pucukAbstractCosmos 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.

Abstract

Lettuce (Lactuca sativa L.) is one of the vegetables that are commonly cultivated by using hydroponic systems. Some hydroponic systems require high current expenses in particular for the electricity in order to circulate nutrient solution e.g. in the water culture system – deep flow technique (DFT) -. Electricity costs can be reduced by changing from continuous nutrient flow to intermittent nutrient flow. The aim of this research was to investigate the effect of interval nutrient flow on growth and yield of lettuce. The experiment was conducted in Cirebon from February to April 2018. The experiment was arranged by using randomized complete block design with four treatments: (i) continuous nutrient flow (control), intermittent nutrient flow (nutrient flow during (ii) 15 minutes, (iii) 30 minutes, and (iv) 45 minutes). For each intermittent treatment, the nutrient flow was interrupted for 60 minutes. Each treatment was repeated four times. The result showed nutrient flow interval affected to plant height, shoot diameter, and leaf area at 35 days after planting (DAP). Meanwhile, leaves number, root volume, and fresh weight of harvested crops were not significantly different in all nutrient interval treatments. The highest plant height and shoot diameter were detected in the treatment (ii) nutrient flow during 15 minutes and interruption for 60 minutes, the results were not significantly different to the control – continuous flow treatment. It can be concluded the interval nutrient flow can be used as an alternative of the continuous flow of nutrient solution in hydroponically DFT.

Abstract

Pemangkasan (defoliasi) daun pada tanaman jagung terutama daun yang tidak produktif dianggap dapat meningkatkan hasil pada tanaman jagung karena mengurangi persaingan penggunaan hasil fotosintesis pada tanaman. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh posisi dan waktu pemangkasan daun terhadap hasil tanaman jagung. Penelitian dilaksanakan di Kabupaten Kuningan Jawa Barat dari Bulan Juni sampai September 2018. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) yang terdiri atas 10 perlakuan yaitu kontrol (tanpa pemangkasan), pemangkasan tiga daun atas umur 50 hari setelah tanam (HST), pemangkasan satu daun atas dan dua daun bawah umur 50 HST, pemangkasan tiga daun bawah umur 50 HST,  pemangkasan tiga daun atas umur 55 HST, pemangkasan satu daun atas dan dua daun bawah umur 55 HST, pemangkasan tiga daun bawah umur 55 HST, pemangkasan tiga daun atas umur 60 HST, pemangkasan satu daun atas dan dua daun bawah umur 60 HST, dan pemangkasan tiga daun bawah umur 60 HST. Masing-masing perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa panjang tongkol, diameter tongkol, bobot tongkol, serta bobot tongkol per tanaman dan per petak tertinggi diperoleh pada perlakuan pemangkasan tiga daun bagian bawah pada umur 50 HST. Daun bawah seringkali ternaungi sehingga tidak aktif berfotosintesis sehingga menjadi organ sink dan berkompetisi dengan tongkol dalam memperoleh hasil fotosintesis.
