Abstract

Aglaonema “Lipstik” merupakan Aglaonema hibrida yang memiliki corak warna merah atau merah muda pada tepi daun sehingga diberi nama lipstik. Keunikan dan variasi warna daunnya, Aglaonema “Lipstik” dimanfaatkan sebagai penghias ruangan seperti ruang tamu, kantor dan hotel. Selain karena indah, tanaman ini mampu menyerap polusi udara di dalam ruangan. Sehingga banyak pecinta tanaman hias membudidayakannya. Dalam prosesnya, diperlukan perawatan agar memperoleh daun yang indah dengan menggunakan pupuk. Eceng gondong (Eichornia crassieps) dapat diolah menjadi pupuk organik cair (POC) karena memiliki kandungan unsur organik yang dapat digunakan untuk pertumbuhan tanaman. Tujuan utama penelitian ini adalah untuk mengetahui respon pertumbuhan Aglaonema “Lipstik” yang diberi pupuk organik cair eceng gondok. Metode penelitian menggunakan rancangan acak lengkap yang terdiri dari empat konsentrasi perlakuan POC (0 ppm, 1,5 ppm, 3 ppm dan 4,5 ppm) dalam enam kali pengulangan. Parameter pengamatan meliputi pertambahan jumlah daun, pertambahan tinggi tanaman, luas daun dan warna daun. Hasil penelitian menunjukkan bahwa POC eceng gondok tidak berpengaruh terhadap beberapa parameter yaitu pertambahan tinggi tanaman, jumlah daun, luas daun dan warna hijau daun. Sedangkan pada parameter penambahan kecerahan warna merah daun berpengaruh signifikan pada konsentrasi 4,5 ppm sebesar 3,5%.

Abstract

AbstractThis study aimed to determine the composition and structure of Semayang forest and the Importance Value Index (IVI) of riparian forest in its role of reducing the wave rate. The method used is multilevel plot method of 20x20 m for sampling of tree level, 5x5 m for sapling level and 2x2 m for seedling level. The result showed that the highest Importance Value Index at tree level was dominated by 3 species, they were L. javanicum (101,663), M. speciosa (76,201) and G. renghas (65,962). At sapling level dominated by P. indica (102,990). At seedling level dominated by M. pigra (95,004)andP. brevistipitata (70,109). In addition, Semayang riparian forest has an ecological function as a wave retaining. It can be seen based on the vegetation density and horizontal structure of species that make up the forest. Vegetation density is predicted to reduce the rate of Semayang lake waves that occur during flood season. Keywords: Composition and Structure, Riparian Forest, Semayang Lake.

Abstract

The forest areas in Delta Mahakam were decreasing annually and it has been impact directly to wildlife which used these forests as food sources and live on it. One of those species is proboscis monkey (Nasalis larvatus Wurmb.), a rare and endemic species of Kalimantan. Research on feeding behavior and ecological can be used in the effort to habitat preservation and protection of proboscis monkey in that area. The aims of this study was to determine the natural feeding plants which used and the feeding behavior by proboscis monkey (N. larvatus Wurmb.) along Kutai Lama Dalam River, Tanjung Una and Muara Sanga-sanga on Kutai Kartanegara regency, East Kalimantan. The research was conducted in June to July 2014. The method used in this study was direct observation, data collection, sampling, herbarium preparation and identification of herbarium plant species. Observations carried out 2 times a day at 08:00 to 10:00am and 16:00 to 18:00pm for 30 days observation. The results was obtained 18 plants of species categorized as natural feeding plants of proboscis monkeys, 6 of them is the main feed (Ficus benjamina L., Sonneratia caseolaris L. Syzygium grande Wight. Gluta rengas L., Gluta wallicii Hook. and Heritiera ellata Ridl), and the rest of them was a food supplement. The Ficus benjamin L. has the highest percentage of feeding sources (44, 8%), whereas the leaves (95,64 %) was the highest part to consumed. The feeding behavior of proboscis monkey along river in Kutai Lama Dalam generally start with foraging activity, and later was the activity of taking and putting food into the mouth. The difference in feeding behavior was showed based on the type of plants consumed by the proboscis monkey. Key words:  Natural plant feed, plant identification, proboscis  monkey (Nasalis larvatus Wurmb.), Delta Mahakam

Abstract

This study aimed to know the types of secondary metabolite compounds contained in the ethanol extract of leaves laban ara (Endospermum peltatum Merr.) and the knowing the magnitude of the antibacterial activity of ethanol extract from the leaves of the laban ara (Endospermum peltatum Merr.) the growth of bacteria Staphylococcus epidermidis. The activity was shown by clear zone surrounding. The experimental design was using Complete Randomized Design (CRD), consisting six treatments, solution concentration of 10%; 20%; 40%; 80% chloramphenicol as the (positive control) and etanol as (negative control), by using four replications. The result of this study indicate that ethanol extract of leaves laban ara (Endospermum peltatum Merr.) compounds positive flavonoid, alkaloids, triterpenoid and steroid well as tannins. From antibacterial test result has been done shows that ethanol extract of leaves laban ara have inhibitory at all levels the concentrations to be tested. At concentrations of 10% namely on average by 3,067 mm, concentrations of 20% average by 3,945 mm, concentrations of 40% average by 4,312 mm and concentrations of 80% average by 4,777 mm. These results indicated that ethanol extract of leaves laban ara showed antibacterial properties, although still below chloramphenicol.

Abstract

The use of plants has an impact and invaluable knowledge and a wealth of culture that needs to be excavated and preserved so that traditional knowledge about plants remain attached and not lost inedible by age. This research was conducted in the District of Berau tribal communities Sambaliung (Bebanir Bangun and Gurimbang village). Data were collected through semi-structured interviews, field exploration, literature studies, sample preservation, processing and manufacturing of herbarium specimens. Based on the results of research conducted in Bebanir Bangun dan Gurimbang, District Sambaliung, Berau district in obtaining 78 kinds of medicinal plants derived from 38 families and be used as an alternative medicine community. Habitat herbs include yard (56%), riparian (9%), forest (5%) and others (30%) of medicinal plants. Based on the processing method generally tribal communities Berau Bebanir Bangun dan Gurimbang village cultivate medicinal plants to be used in a way crushed and then taped (47%), boiled and drunk (26%), burned or heated (8%), kneaded and massaged (6%), cleaned and then affixed to 5%), grated and filtered (4%), chewed (3%) and flattened (1%).

Abstract

This studied aim to find out the traditional medicinal plants that used by communities at Kutai area in the subdistrict of Muara Bengkal, how the Kutai community obtains a medicinal plants and which part of the plant that used as a traditional medicine. In this studied we used PRA (Participatory Rural Appraisal) methods, interview open-ended technique and the informant was determined by using snowball sampling. Stages of research include survey, observation, interviews, sampling, doing the identification of the herbarium and data analysis using Microsoft Excel 2007. There are 82 species of medicinal plants that are grouped into 42 families was found in this research. The Kutai community gained the medicinal plant by planted on their home garden, took on the field, looking for in the forest and bought in the market. The plant parts that used as a traditional medicine are the leaf, rhizome, stem, fruit, root, bark, seeds, tree sap, bulbs and the entire section.
