Abstract

Hutan hujan tropis sangat berstratifikasi. Stratifikasi yang terbentuk dalam vegetasi hutan tergantung pada tipe hutan. Strata atas didominasi oleh pohon, sedangkan strata bawah diisi oleh semak, herba, maupun liana. Penelitian tentang struktur vegetasi pohon atau penyusun strata atas telah banyak dilakukan, namun penelitian tentang vegetasi semak masih sangat jarang.  Dominansi dan komposisi tumbuhan semak dan herba dapat menjadi penciri tipe habita. Penelitian ini bertujuan menganalisis komposisi, keanekaragaman, dan kekayaan jenis vegetasi semak di hutan dataran rendah CA Pangandaran.  Penelitian dilakukan dengan analisis vegetasi metode Line Intercept. Cuplikan yang dilakukan pada ekosistem hutan dataran rendah menemukan 6 spesies semak berikut INPnya sebagai berikut : Mischocarpus sp. (110.34), Psicontria viridiflora (62.17), Ixora sp. (44.48), Dillenia excelsa (37.56), Barringtonia racemosa (28.27), danRhodamnia rubescense (17.18). Sedangkan pada daerah ekoton ditemukan 8 spesies semak yaitu Psicontria viridiflora (66.93), Sambucus javanica (52.05), Clidemia hirta (43.96), Kebojalu (37.11), Micromelum pubescens (36.65), Mischocarpus sp. (28.34), Morgania ( 27.18), dan Dillenia excelsa (7.78). Baik indeks keragaman Shannon [10] (1,458) maupun indeks kekayaan Margalef [4] (1,573) spesies semak di hutan lebih kecil daripada di daerah ekoton (1,717 dan 1,882). Kata kunci: tumbuhan semak, hutan, dataran rendah

Abstract

Green consumerism has been considered as one of promising movement in maintaining the environmental quality. This research aimed to describe the students’ pro-environmental behavior (PEB) as considerable as there learning outcome based on green consumerism. This survey research was conducted in State Junior High School 1 of South Tambun, Bekasi, West Java on July-August 2018. The sampling technique used was simple random sampling with 256 students. The subject was divided into two groups: 128 students from seventh grade who had not received environmental learning materials and 128 students from eighth grade who had received environmental learning materials. The data analysis used in this study was an independent t-test. The results of the t-test showed that there was no significant difference of PEB achievement between the two groups. In addition, not with standing that the average of the students’ environmental learning outcomes was 72.76, but there was as high as 78.60% of students’ achievement was classified below the standard value. Thus, teachers should evaluate the environmental materials used. It is expected that Biology subjects on environmental material can accommodate green consumerism concepts.

Abstract

Environmental responsibility is a crucial aspect which determines the environmental solving problems in term of enhancing the pro-environmental behavior. This study aimed to examine the relation between the environmental responsibility and pro-environmental behavior of the undergraduate students. The sample of this descriptive correlational study was 106 students of biology education department which was taken randomly. This study showed that the undergraduate students were in high criteria of environment responsibility (ER). This was represented by feeling guilty which was the highest percentage and followed by responsibility feeling and responsibility judgment respectively. In addition, the undergraduate students were in positive pro-environmental behavior (PEB). The regression model was y = 23.876 + 0.623x; while ER contributed as high as 22.1% to the undergraduate student’s PEB. This implied that to improve the undergraduate student’s PEB is by strengthening their ER.

Abstract

Understory plants are a group of plants that form a layer near the surface of the soil. One of the functions of undergrowth is as a ground cover which contributes to increasing the organic matter content in the soil. This research was conducted in November 2023 in the garden behind the KH. Hasyim Asy'ari Building, Jakarta State University. The aim of this research is to determine the diversity of understory plants found in the Jakarta State University environment. The research method used was a survey using a sampling technique with a quadratic method. There are 4 types of undergrowth in the garden behind the KH. Hasyim Asy'ari Building, namely Cyanthillium cineroum, Pilosela officinarum, Eclipta prostrata, and Cynodon dactylon. The results of the calculation of the Shannon-Wiener diversity index based on its classification show that the garden behind the KH. Hasyim Asy'ari Building, Jakarta State University has a low level of understory plant diversity.

Abstract

Microalgae are microscopic unicellular organisms that have varying sizes, shapes, and types, have photosynthetic pigments, are photoautotrophic, and are found in aquatic environments. Microalgae have certain limits of tolerance to water chemical physics factors. The presence of microalgae in water can be used as an indicator of the state of the water. This study aims to identify the diversity of microalgae as an indicator of the water quality present in the river around the Ragunan Margasatwa crocodile cage. Sampling was done in the Ragunan Margasatwa Park river near the crocodile cage. Samples of macroalgae are visually identified and include morphology, color, shape, and other characteristics. Based on the observations, it can be concluded that the river ecosystems around the crocodile cages are under low ecosystem pressure. The diversity index generally has a range of values between 1.5 and 4, and lower values reflect increasing ecosystem instability. The lowest microalgae density was found at station 1, which is 120 ind/ml. Individuals with the highest density at station 2, the species Aphanothece sp. with a density value of 293.3 ind/mL.

Abstract

Ketinggian pohon adalah faktor yang dapat mempengaruhi kualitas pohon dan memperkirakan berbagai parameter seperti biomassa, cadangan karbon, pertumbuhan pohon, dan sebagainya. Artikel ini bertujuan untuk mengetahui ukuran tinggi dari beberapa pohon di Ragunan menggunakan alat klinometer yang mana memiliki manfaat juga untuk mengetahui faktor-faktor yang mempengaruhi pertumbuhan pohon, termasuk iklim, ketersediaan air dan juga interaksi dengan spesies lain. Metodologi penelitian artikel ini menggunakan metode deskriptif kuantitatif. Hasil yang didapatkan adalah Ficus sp. Sebagai pohon paling tinggi, yaitu 18,05 meter dan pohon Syzygium aqueum yang terpendek dengan tinggi 3,3 meter yang dihitung menggunakan phytagoras. Kesimpulannya, semakin tinggi pohon menandakan bahwa lingkungan tersebut memiliki kondisi yang baik untuk tempat tumbuh vegetasi, sehingga kondisi tanah pada pohon Ficus sp. memiliki kondisi tanah yang lebih baik daripada kondisi tanah pada pohon Syzygium aqueum. The height of trees is a factor that can influence tree quality and estimate various parameters such as biomass, carbon reserves, tree growth, and so forth. This article aims to determine the height measurements of several trees in Ragunan using a clinometer, which also serves to identify factors affecting tree growth, including climate, water availability, and interactions with other species. The research methodology of this article employs a quantitative descriptive method. The results indicate that Ficus sp. is the tallest tree, measuring 18.05 meters, while Syzygium aqueum is the shortest at 3.3 meters, calculated using the Pythagorean theorem. In conclusion, taller trees signify that the environment provides favorable conditions for vegetation growth, indicating that the soil conditions for Ficus sp. are superior to those of Syzygium aqueum.
