Abstract

Wild flowering plants that are included in the understorey are plant communities that make up lower stratification near the surface of the ground. Effects of forest boundaries can be seen from gradual changes in microclimates and vegetation patterns from the edge of the forest to the forest. The impact of meeting these two different environmental conditions for plants and animals is called edge effect. Forest boundaries also have an impact on changes in environmental factors including temperature, humidity, light intensity, soil pH and canopy cover. These factors are thought to influence the diversity of wild flowering plants. The results of the study showed that there were 43 species of wild flowering plants in Bantarbolang Nature Reserve with a total of 978 individuals included in 22 families. The most common type is Piper caducibrachteum as many as 183 individuals. The edge effect has an effect on the diversity of wild flowering plants as evidenced by the increasing number of species obtained tends to be less. Wild flowering plants that have the highest index of importance are Piper betle (66.55%) followed Piper caducibrachteum (52.44%) and Ageratum conyzoides (46.17%). The most influential environmental factors in wild flowering plant diversity are light intensity. The intensity of the light getting deeper into the forest is lower because the sunlight entering the forest is blocked by tree canopies.

Abstract

A red chili plant (Capsicum spp.) is one of the horticultural commodities in Indonesia which has good economic value, so it has priority to be developed. Agriculture practices in Java island have partly switched to coastal areas which have characteristics of saline soils. Saline soils are alkaline and nutrient-poor, especially essential nutrients such as P and N. One way to restore fertility in saline soils used beneficial and fertilizing bacteria such as PGPR. Plant growth-promoting rhizobacteria (PGPR) are free-living, soil-borne bacteria, which are capable of enhancing the growth of the plant either directly or indirectly. The objectives of this research were to determain the effect of PGPR isolates to the growth of red chili plants in saline sandy soil and to determine the best PGPR isolate capable to improve the growth of red chili plant in saline sandy soil. The result showed that the inoculation of rhizobacteria significantly affected to plant height and root length of the red chili plant (Capsicum annum). The combination of 3 PGPR isolates (Azospirillum PSA 10, Azotobacter PSA 8, and Marinococcus PSA 1) was the best result in increasing the height and root length of the chili plant (Capsicum annum).

Abstract

Undergrowth is ground cover plant which is generally in the form of herbs, grass or low shrubs. Mostly undergrowth is flowering plants. The Flower is part of plant for generative reproduction that consists of several organs that consist of pedicellus, receptacullum, perianthium, pistillum and stamen that contain pollen. Pollen is part of the flower that functions as a generative reproduction agent because it contains male gamete. Pollen has a distinctive character in each plant so that it can be used as a tool for identifying plants. Sampling location was conducted in Bantarbolang Nature Reserve, a conservation area located in Kebon Gede Village, Bantarbolang District, Pemalang Regency. The objective of research is to know the morphological character of undergrowth pollen in the Bantarbolang Nature Reserve. The research used a survey method with explorative sampling techniques.

Abstract

Limbah batik merupakan salah satu penyebab pencemaran di lingkungan perairan karena diketahui mengandung beberapa jenis logam berat. Jenis logam berat tersebut antara lain seperti krom (Cr), seng (Zn), merkuri (Hg), tembaga (Cu), timbal (Pb), Arsen (As), kadmium (Cd), mangan (Mn) dan nikel (Ni). Ikan yang terpapar limbah batik memberikan respon secara fisiologis. Respon yang muncul sebelum ikan mengalami kematian disebut efek subletal. Ikatan antara logam berat atau metal (M) dengan protein metalotionin ini disebut sebagai ikatan M+Mt. Ikatan ini bersifat stabil sehingga tidak mudah lepas. Hal inilah yang akhirnya memicu pembentukan radikal bebas. Ketika radikal bebas dalam tubuh semakin meningkat, maka kadar enzim Superoksida Dismutase atau SOD akan semakin menurun. Pengujian kadar enzim SOD dapat dijadikan sebagai upaya deteksi dini adanya pencemaran perairan yang disebabkan oleh limbah batik. Berdasarkan hal tersebut, maka penelitian ini memiliki tujuan untuk melihat pengaruh toksisitas limbah batik terhadap penurunan enzim SOD pada ikan nila. Berdasarkan hasil penelitian ini, kadar SOD mulai dari kontrol, konsentrasi 17% v/v, 34% v/v dan 51% v/v berturut-turut yaitu 29,48 ± 1,40 U/mL, 22,20 ± 1,18 U/mL, 17,77 ± 1,16 U/mL, 13,68 ± 0,56 U/mL. Hasil analisis data menunjukkan bahwa nilai F hitung (218,570) > F tabel (4,30) yang artinya terdapat pengaruh paparan limbah batik terhadap penurunan aktivitas SOD. Semakin tinggi konsentrasi limbah batik maka semakin rendah aktivitas SOD. Kata kunci: Limbah Batik, Oreochromis niloticus, Superoksida Dismutase (SOD)
