Abstract

Abstrak. Penelitian ini bertujuan untuk mengetahui stomata daun mangga (Mangifera indica) di daerah dengan kondisi lingkungan yang berbeda. Penelitian bersifat deskriptif analisis. Pengambilan sampel dilakukan melalui survey secara acak di Cagar Alam Pananjung Pangandaran dan salah satu ruas jalan di Kecamatan Pangandaran Kabupaten Pangandaran. Paramater yang diamati adalah kerapatan dan kerusakan stomata. Selain itu diukur juga luas daun, berat partikel debu yang menempel di daun, serta beberapa faktor lingkungan fisik seperti intensitas cahaya, suhu, dan kelembaban udara. Hasil penelitian menunjukkan bahwa kerapatan dan kerusakan stomata daun mangga (Mangifera indica) yang tumbuh di pinggir jalan yang banyak dilalui kendaraan bermotor lebih besar dibanding di Cagar Alam.Kata kunci: stomata, Mangifera indica Abstract. The study aims to determine the stomata of the leaves of mango (Mangifera indica) in areas with different environmental conditions. The research is descriptive analysis. Sampling was done through a random survey in Pananjung Pangandaran Nature Reserve and one of the roads in Pangandaran Sub District, Pangandaran District. The observed parameters are the density and stomatal damage. Moreover measured the leaf area, weight of the particles of dust off the leaves, as well as some physical environmental factors such as light intensity, temperature, and humidity. The results showed that the leaf stomatal density and damage to mango (Mangifera indica), which grows in the street that many passed the motor vehicle is greater than in the Nature Reserve.Keywords: stomata, Mangifera indica

Abstract

The purpose of this study was to get the best combination of BAP with organic material extract that can enhance the growth of Dendrobiumsp shoot in the VW media. The method used was experimental with completely randomized design, which consists of 12 treatments namely combination of BAP concentration with organic material extract. BAP concentration consisted of 4 levels i.e. 1 ppm, 2 ppm, 3 ppm and 4 ppm. The organic material extract used consisted of 3 types of extracts namely tomato extract, corn extract and banana extract, each of 100 mL/L. Each treatment was repeated 3 times. Data were analyzed using Analysis of Variance (Anova) and Duncan 's multiple range test. The results showed that the average of the fastest shoots emergence time obtained on combination of BAP 2 ppm + banana extract was 1.33 days after planting, the average of the highest shoot number was 14 buds obtained on the combination of BAP 3 ppm + tomato extract, and the average of the highest shoots length was 2.06 cm obtained on a combination of BAP 2 ppm + tomato extract. Keywords : BAP, Dendrobium sp., Extract, VW

Abstract

Spinach (Amaranthus tricolor L.). is one of the vegetables that are economically valuable with high nutrient content to support public health so that its production needs to be improved. The purpose of study was to obtained the optimal dosage of kascing organic fertilizer and the thickness of the bamboo leaf litter mulch on increase growth of spinach. The research used experimental method with randomize block design (RBD), two factors and three replications. The first factor was the adding of kascing organic fertilizer (K), consist of five levels doses, i.e: without adding kascing fertilizer (k0); 2.5 g/kg of soil (k1); 5 g/kg of soil (k2); 7.5 g/kg of soil (k3) and 10 g/kg of soil (k4). The second factor was bamboo leaf litter mulch (M), consist of three levels, i.e: without mulch (m0); mulch with thickness of 2.5 cm (m1); mulch with thickness of 5 cm (m2). Parameter observed were the plant height, the number of leaves, the leaf area, the shoot dry weight and the root dry weight. The data obtained was analyze using Anova and Duncan’s Multiple Range Test (α=5%). The results showed that interaction between dosage of kascing fertilizer with bamboos leaves litter mulch could increase the average of plant height (50.17 cm), number of leaves (40.33 leaves), shoot dry weight (5.77 g) and root dry weight (1.78 g) of spinach. Commonly, kascing organic fertilizer dose of 5 g/kg of soil (k2) and bamboos leaves litter mulch on the tickness of 5 cm (m2) combination was the best treatment for growth of spinach. Keywords: bamboo leaf litter, mulch, organic fertilizer of kascing, spinach

Abstract

Indonesia adalah negara yang memiliki keragaman suku bangsa dan budaya, termasuk pengetahuan tradisional di dalamnya. Salah satu pengetahuan yang ada di masyarakat adalah pengetahuan mengenai pemanfaatan tumbuhan. Penelitian ini dilakukan untuk mendokumentasikan pemanfaatan jenis-jenis tumbuhan famili Zingiberaceae oleh masyarakat desa di kawasan Wisata Pantai Rancabuaya Kecamatan Caringin Kabupaten Garut. Metode yang digunakan dalam penelitian ini adalah metode kualitatif bersifat deskriptif analisis. Teknik pengumpulan data dilakukan dengan cara observasi langsung dan wawancara semistruktur terhadap informan kunci. Penentuan informan dilakukan dengan teknik snowball sampling. Hasil wawancara menunjukan bahwa terdapat 12 jenis tumbuhan famili Zingiberaceae yang dimanfaatkan masyarakat, yaitu laja bodas (Alpinia galanga (L.) Willd.), laja beureum (Alpinia purpurata K. Schum.), kapolaga (Amomum cardamomum Maton), koneng temen (Curcuma domestica Val.), koneng gede (Curcuma xanthorrhiza Roxb.), cikur (Kaempferia galanga Linn.), jahe gajah (Zingiber officinale var. Roscoe), jahe emprit (Zingiber officinale var. Amarum), jahe beureum (Zingiber officinale var. Rubrum), koneng bodas (Curcuma zedoaria (Berg.) Rosc.), lempuyang wangi (Zingiber aromaticum Val.), dan panglay (Zingiber cassumunar Roxb.). Berdasarkan genusnya, masyarakat memanfaatkan Alpinia, Amomum, dan Kaempferia sebagai bumbu masak dan obat; Curcuma sebagai bumbu masak, bahan jamu, dan obat; serta Zingiber sebagai obat, bumbu masak, bahan minuman, dan ritual adat. Tumbuhan-tumbuhan tersebut merupakan tumbuhan liar dan hasil budidaya yang diperoleh dari pekarangan, kebun, dan sawah. Indonesia is a country that has a diversity of ethnic groups and cultures, including traditional knowledge in it. One of the existing knowledge in society is knowledge about the use of plants. This research was conducted to document the utilization of Zingiberaceae family of plant species by rural communities in the Rancabuaya Coastal area of Caringin District, Garut Regency. The method used in this research is descriptive qualitative analysis. Data collection techniques were carried out by direct observation and semistructured interviews of key informants. Determination of informants is done by snowball sampling technique. Interview results show that there are 12 species of plants of the Zingiberaceae family that are utilized by the community, namely laja bodas (Alpinia galanga (L.) Willd.), laja beureum (Alpinia purpurata K. Schum.), kapolaga (Amomum cardamomum Maton), koneng temen (Curcuma domestica Val.), koneng gede (Curcuma xanthorrhiza Roxb.), cikur (Kaempferia galanga Linn.), jahe gajah (Zingiber officinale var. Roscoe), jahe emprit (Zingiber officinale var. Amarum), jahe beureum (Zingiber officinale var. Rubrum), koneng bodas (Curcuma zedoaria (Berg.) Rosc.), lempuyang wangi (Zingiber aromaticum Val.), dan panglay (Zingiber cassumunar Roxb.).  Based on its genus, people use Alpinia, Amomum, and Kaempferia as cooking spices and medicines; Curcuma as cooking spices, herbal ingredients, and medicine; and Zingiber as medicine, cooking spices, beverage ingredients, and traditional rituals. These plants are wild plants and cultivation results obtained from the yard, garden, and rice fields.
