Abstract

Abstrak : CIFOR adalah organisasi penelitian ilmiah yang berfokus pada hutan tropis di negara-negara berkembang dan dikelilingi oleh hutan sekunder dan daerah pemukiman. Peningkatan jumlah pemukiman telah menyebabkan perubahan habitat kupu-kupu dan dapat mengurangi populasi kupu-kupu di daerah tersebut. Tujuan dari penelitian ini adalah untuk mempelajari keragaman kupu-kupu di daerah CIFOR berdasarkan habitat yang berbeda dan hubungan keragaman kupu-kupu dengan faktor lingkungan. Pengamatan dilakukan dengan metode scan sampling pada pagi dan sore hari di dua lokasi yaitu, hutan sekunder dan daerah perumahan. Hasil penelitian menunjukkan bahwa 59 spesies dan 441 individu kupu-kupu ditemukan di daerah tersebut dalam waktu 8 minggu pengamatan. Di hutan sekunder dan daerah perumahan ditemukan 42 spesies (256 individu), dan 40 spesies (174 individu) kupu-kupu. Keragaman kupu-kupu lebih tinggi di daerah tersebut (H '> 3), di mana kawasan perumahan memiliki nilai lebih tinggi (H' = 3,34) daripada hutan sekunder (H '= 3,16). Indeks kesamaan Sorensen (CN) menunjukkan bahwa dua lokasi adalah struktur komunitas yang berbeda karena ada beberapa spesies dominan yang berbeda di setiap lokasi. Secara statistik, kecepatan angin memberikan pengaruh lebih signifikan pada jumlah individu kupu-kupu daripada parameter iklim lainnya. Hasil penelitian ini disarankan bagi CIFOR untuk lebih memperhatikan kondisi habitat kupu-kupu, terutama tumbuhan pakan larva yang makin berkurangKata kunci: Kupu-kupu, CIFOR, Papilionoidea, Hutan Sekunder, Daerah Pemukiman.Abstract : CIFOR is a scientific research organization that focus on tropical forests in developing countries and the area were surrounded  with secondary forest and residential areas. Increasing number of residential area have caused changes of the butterfly habitat and may decrease butterfly population in the area. Aim of the research was to study the diversity of the butterflies in CIFOR area based on different habitats and the relation diversity of butterflies with environmental factor. The observations were done by scan sampling method in the morning and afternoon at two locations i.e., secondary forest and residential area. Results showed that 59 spesies and 441 individual of butterflies were found at the areas within 8 weeks of observation. At secondary forest and residential area were found 42 spesies (256 individu), and 40 spesies (174 individu) of butterflies. The diversity of butterflies was higher in the areas (H’ > 3), where residential area has higher value (H’ = 3,34) than secondary forest (H’ = 3,16). Sorensen similarity index (CN) showed that two locations were different community structures because there were several different dominant species at each location. Statistically, wind speed gave more significant influence on the number butterfly individuals than other climate parameters. It is recommended for CIFOR to pay more attention to the butterfly habitat conditions, especially the diminishing larval feed plants.Keywords: Butterfly, CIFOR, Papilionoidea, Secondary Forest, Residential Area.

Abstract

Abstract : The need for environmental protection continues to increase, so exploratory studies of agents of polluted environmental indicators are becoming increasingly important. The advantages of using flowering plants for environmental bio-indicator studies include the availability of sufficient test material with their variations and the availability of different periods for sampling. Seven plant species were used to examine their suitability as bio-indicator for genotoxicity of polluted atmospheric environment in Mataram City by microspore analysis. This study was conducted with the aim of, 1) knowing the level of difference in the frequency of failure (abortiveness) of microspores between similar plants that grow in areas at risk of being polluted in the city and those growing in areas not at risk of being polluted outside the city of Mataram, and 2) find out what types of flowering plants, especially those in city parks that are suitable as bio-indicators of air pollution for Mataram City. The percentage of aborted pollens was calculated out of 50 to 300 observed pollen grains of each selected individual flowering plant. Sample of each plant species from every study area consist of ten plant individuals. Data were analyzed by use the Wilcoxon one way-test at a 0.05 to determine significance of difference in the percentage of aborted pollen grains from same plant species between in the risky polluted area and plant in the control area.  The results showed that Lantana camara L. is suitable as bio-indicator for atmospheric pollution in Mataram City or other cities that have a density of traffic flow of motorized vehicles around 100 vehicles per hour. Its percentage of aborted pollen grains is 1,62 ±  0,08 % in the risky polluted area,  and   1,21 ± 0,13 % in the control area. Others six observed plant spesies, i.e.  Acacia auriculiformis A. Conn. Ex Bth., Bauhinia acuminata L., Baugenvillea spectabilis Willd. Duranta erecta L., Ixora coccinea L. and Rosa hybryda Hort., each of them is not suitable as bioindicator for it. Their percentage of pollen abortiveness in polluted and not-polluted areas were not different, significantly.Keywords: Genotoxicity, Microspores, Polluted air environment

Abstract

Abstrak : Pemupukan anorganik pada sistem budidaya pertanian menimbulkan beberapa masalah, antara lain biaya produksi meningkat, pendapatan petani menurun, tanah menjadi keras dan tidak subur, serta mencemari lingkungan. Karena itu, perlu ada upaya untuk menemukan sumber bahan baku pupuk yang mudah didapat, murah dn ramah lingkungan. Beberapa peneliti sebelumnya melaporkan bahwa rumput laut mengandung fitohormon dan elemen essensial yang dapat merangsang pertumbuhan dan hasil tanaman. Artikel ini melaporkan pengaruh ekstrak cair dan padat Sargassum aquifolium terhadap pertumbuhan dan hasil tanaman mentimun. Ekstrak cair dan padat alga tersebut diperoleh dengan metode Godlewska et al., 2016. Ekstrak cair (10%) disemprotkan satu kali seminggu selama pertumbuhan vegetatif. Ekstrak padat (5%) diberikan pada media tanah saat tanam. Ekstrak cair secara signifikan mempengaruhi sebagian besar parameter pertumbuhan (tinggi tanaman, jumlah cabang dan berat kering tunas) dan pertumbuhan generatif (jumlah dan berat buah per tanaman), namun ekstrak cair tersebut tidak secara signifikan mempengaruhi berat kering akar. Fenomena serupa juga ditemukan pada pengaruh ekstrak padat terhadap pertumbuhan dan hasil tanaman mentimun. Hasil penelitian ini memberikan indikasi bahwa ekstrak cair yang dilaporkan mengandung fitohormon, dan ekstrak padat yang mengandung elemen essensial dapat dikembangkan sebagai “biostimulan” dan “biofertlizer” organik yang dapat memacu pertumbuhan dan produksi tanaman.Kata kunci : ekstrak cair, ekstrak padat, Sargassum quifolium, pertumbuhan, hasil, tanaman mentimun.Abstract : Aplication of inorganic fertilizer in agriculture cultivation system causes some disadventages, such as increase cost production, reduce farmer’s income and soil fertility, and hqrm our environment. Therefore, it is needed to find out raw materials for fertilizer which easy to obtain, cheap and adaptive to our environment. Previous researchres reported that seaweed contained plant growth hormones and essential elements stimuliting growth and yield of plants. This article reports effect of liquid and solid extracts of Sargassum aquifolium on growth and yield of cucumber plants. Liquid and solid extracts were obtained according to modified Godlewska method (2016). Liquid extract (10%) was sprayed once a week during vegetative growth. Moreover, solid extract (5%) was applied in plant media. Liquid extract influenced significantly most growth parameters, such as plant height, branch number, shoot dry weight and yield parameters like fruit number and fruit weight per plant, but liquid extract did not significantly affect root dry weight. Similar phenomena was also found on the effect of solid extract on growth and yield of cucumber plants. The results suggest that liquid and solid extracts containg plant growth hormones and essential element respectively, could be developed as organic biostimulant and biofertilizer inducing growth and plant production.Keywords : liquid extract, solid extract, Sargassum quifolium, growth, yield, cucumber plants.
