Abstract. Darmawati, Mulyadi A, Suwondo, Harto S. 2021. The diversity and vegetation structure based on growth levels at an urban green campus in Pekanbaru City, Indonesia. Biodiversitas 22: 5123-5132. The Bina Widya campus of the University of Riau (UNRI), Pekanbaru, Indonesia has the green open space (GOS) in its area and there are many species of vegetation. In a green open space, variables like diversity and vegetation structure must be considered based on growth levels, this study intended to determine the composition, structure, and diversity of vegetation.The results showed that there were 33 species of trees, 29 species of poles, 16 species of saplings, and 8 species of seedlings from 44 species belonging to 22 families. There were 874 individuals which consisted of 534 trees, 207 poles, 87 saplings, and 46 seedlings. The most common species found was Swietenia macrophylla King (Meliaceae) with 289 individuals. The highest Important Value Index of vegetation species at each growth level was the tree of Alstonia scholaris (L) R.Br (300%, location IX), the pole of Hibiscus tiliaceus L. (300%, location VII), saplings of Vitex pinnata L. (300%, location IV), and S. macrophylla King (300%, locations I), seedlings of S. macrophylla King (300%, location I), and Garcinia mangostana L (300%, location IX). We did not find vegetation species at the levels of sapling or seedling in locations of II, III, V, VI, and VIII. It is necessary to replant the vegetation. The highest Species Diversity Index (H') at location X was trees (2.34), poles (2.28), saplings (1.77), and seedlings (1.17). The average H’ vegetation at Bina Widya Campus UNRI was 2.44 (medium). Vegetation on the Bina Widya Campus is fairly steady in terms of delivering advantages for human environmental services.

Abstract. Suwondo, Darmadi, Roza D, Murdiya F, Oktarianda R, Risaundi DD. 2023. Mitigation of wildlife disturbance at oil and gas industry electrical facilities in Riau Province, Indonesia. Biodiversitas 24: 6914-6922. Electrical facilities in the oil and gas industry often experience interference from wildlife, disrupting oil and gas operational activities. Solutions are required to mitigate these disturbances. This research analyzes the level of wildlife disturbance in electrical facilities in the oil and gas industry and their mitigation. This research used a survey method with purposive random sampling; the observation was carried out in the work area of Pertamina Hulu Rokan Company, Riau Province, Indonesia. The data obtained are primary and secondary, and the parameters measured consist of population, behavior, disturbance, and mitigation of disturbance to wildlife. A total of 38 species of wild animals were found, consisting of the mammal group (5 species), the reptile group (3 species), and the aves group (30 species). The population of long-tailed monkey (Macaca fascicularis) is the largest species of mammal found (1,500 individuals), and the most common daily behaviors of macaques are climbing (22.5%), eating (17.5%), and playing (15%). There were 169 incidents of wildlife disturbance at the WK Rokan electrical facility, with the most disturbance caused by macaques at 111 incidents. Disturbance from wildlife has a linear positive interaction with wildlife mortality around oil and gas industry electrical facilities. Mitigation is conducted as follows: isolating/eliminating the presence of wild animals in affected facilities/locations, building barriers against wild animals around electrical facilities, and providing repellents.

Abstract

The availability of STEM-based Student Worksheets (LKPD) that present real experimental data for quantitative analysis remains limited in senior high school biology learning, particularly for the topic of Plant Growth and Development. This study aimed to: (1) analyze the effect of dolomite and poultry manure application on the growth of red spinach (Amaranthus tricolor L.) in peatland; and (2) analyze the validity of a STEM-based LKPD on Plant Growth and Development for Grade XII senior high school students developed based on experimental data. The experiment used a Factorial Completely Randomized Design (CRD) consisting of four dolomite doses (0, 24, 36, 48 g/polybag) and four poultry manure doses (0, 180, 270, 360 g/polybag), forming 16 treatment combinations with three replications. Growth parameters measured included plant height, leaf number, root length, fresh weight, and dry weight. Data were analyzed using Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT) at 5% significance level. The LKPD was developed using the ADDIE model with a STEM approach integrated into Discovery Learning, and validated using a Likert scale (1–4) by two expert lecturers and one biology teacher. Results showed that the combination of dolomite and poultry manure significantly affected all growth parameters. The best treatment, D3P3 (48 g dolomite + 360 g poultry manure per polybag), produced the highest plant height of 24.00 cm, an increase of 674.19% compared to the control (3.10 cm), with leaf number 7.67, root length 6.57 cm, fresh weight 7.80 g, dry weight 2.22 g, and soil pH 6.07. The STEM-based LKPD obtained an overall validation score of 3.63 (Very Valid) and is suitable for use as a contextual learning material in Grade XII senior high school biology.

Abstract

Macrofungi are important components of forest ecosystems, functioning as decomposers, supporting biogeochemical cycles, and possessing potential as sources of food, medicine, and biological agents. The presence and distribution of macrofungi are strongly influenced by environmental conditions and the availability of suitable growth substrates. The Sungai Dumai Nature Tourism Park (Taman Wisata Alam/TWA Sungai Dumai) is a conservation area with diverse habitat types that potentially support macrofungal diversity; however, information regarding macrofungal diversity in this area remains limited. This study aimed to identify and describe the diversity of macrofungi found in the Sungai Dumai Nature Tourism Park. An exploratory method was employed using the cruise method and hand-sorting technique across three observation stations representing shaded, transitional, and open areas. The collected specimens were documented, identified based on their morphological characteristics, and analyzed descriptively. The results revealed a total of 30 macrofungal species belonging to 24 genera, 14 families, 7 orders, 3 classes, and 1 division. Station I recorded the highest number of species, with 12 species from 11 genera, followed by Station III with 10 species from 10 genera, and Station II with 8 species from 7 genera. Macrofungi were found growing on various substrates, particularly decaying wood, leaf litter, and soil. The most dominant group belonged to the order Polyporales. Environmental conditions at the study site, including temperature ranging from 22–24°C, humidity of 82–84%, soil pH of 6.3–6.8, light intensity of 885–1839 lux, and soil organic matter content of 1.30–3.20%, were within the optimal range for macrofungal growth. These findings indicate that the Sungai Dumai Nature Tourism Park possesses relatively high macrofungal diversity and has considerable potential as a source of biodiversity data and fungal ecological studies in the Riau region.

Abstract

The use of organic fertilizers is one approach to enhance plant growth while simultaneously utilizing agricultural waste available in the surrounding environment. Empty fruit bunches of oil palm (EFBOP) are solid residues from palm oil processing that have the potential to be used as compost due to their nutrient content, including N, P, K, Mg, and Ca. This study aimed to determine the effect of compost derived from empty fruit bunches of oil palm on the growth of caisim (Brassica juncea L.), particularly in terms of plant height, number of leaves, leaf width, and fresh weight. The study employed an experimental method using a factorial Randomized Block Design (RBD) consisting of seven treatments with three replications. Data were analyzed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that the application of compost had a significant effect on the growth of caisim. The drum compost treatment at a concentration of 3 kg/plot produced the highest plant height, leaf width, and fresh weight, while the EFBOP compost at a concentration of 1 kg/plot resulted in the highest number of leaves. These findings indicate that compost from empty fruit bunches of oil palm is effective as an organic fertilizer to support the growth of caisim.
