Moss plants can live well in areas that have high humidity. The Dutch Guesthouse which is located in the Sultan Adam Mandiangin Forest Park area has quite high humidity because the area has lots of dense plants, so it is a suitable habitat for the living nature of moss plants. This study aims to describe and identify the types of moss found. Data collection was carried out using the total roaming method, which was then followed by determining and identifying each sample of the moss plants found. Data analysis was carried out descriptively and identifying species with reference to the literature. The results of the study found 10 species of mosses belonging to 7 different families, both found in tree, rock and soil habitats. The species found were: Calymperes tenerum, Calymperes afzelii, Hyophila apiculata, Hyophila involuta (Hook.) A. Jaeger, Ectropothecium falciforme, Octoblepharum albidum, Philonotis hastata, Acroporium secundum, Lejeunea lamacerina, and Thysananthus sp. The results of this study are expected to provide information about the variety and biodiversity of mosses in South Kalimantan.

This research aims to analyse Expression of Caspase 3 in Rat Liver Cells With Maximum Physical Exercise After Administration of Gagatan Harimau Nanoherbal (Paraboea leuserensis B.L.Burtt). The research was conducted in April-June 2023. The research location was the Animal Physiology Laboratory and Experimental Animal House, Department of Biology, FMIPA USU, PT. Synergy of Indonesian Nanotech, South Tangerang, Banten and the Anatomic Pathology Laboratory, Faculty of Medicine, University of North Sumatra, Medan. There were 6 treatments in the study, namely control group (K-), maximum physical exercise (K+), maximum physical exercise + Vitamin C at a dose of 2 mg/Kg Body Weight (P1), maximum physical exercise + Gagatan Harimau nanoherbal 100 mg/Kg BW (P2 ), Maximum physical exercise + Gagatan Harimau nanoherbal dose 125 mg/Kg BW (P3), Maximum physical exercise + Gagatan Harimau nanoherbal dose 150 mg/Kg BW (P4). The data obtained from each observation parameter (variable) is recorded and presented in table form. The data was then analyzed using SPSS version 25 software with significant differences determined at p<0.05. The results of the study showed significant differences between all groups (p<0.05) in the expression of caspase 3 in the liver. A dose of 150 mg/Kg BW from the nanoherbal Gagatan Harimau leaves (Paraboea leuserensis B.L.Burtt) reduced the expression of caspase 3 in rat liver. The induction of gagatan harimau leaf nanoherbal to act as an antioxidant in male rats given swimming physical training showed improvements in liver histology and morphology. The dose of 150 mg/KgBW of nanoherbal gagatan harimau leaves was the best dose because it showed cell regeneration that was close to the normal treatment group.

The coal open mining is an activity that has an impact on the environment, including acid mine drainage (AMD). The management of AMD can be done by phytoremediation using Chinese Waterchestnut (Eleocharis dulcis Burm.f.) Trin. ex Hensch.) on system of constructed wetlands (CWs). So the research was carried out with the aim of evaluation the accumulation of heavy metals iron (Fe) and Manganese (Mn) which were absorbed in E. dulcis in constructed wetlands system at WTP Air Laya PT. Bukit Asam. The accumulation of Fe in the roots of E. dulcis was 986.42 ppm (w/w) while the accumulation of Fe in the leaves was 392.22 ppm (w/w). The accumulation of Mn in the roots of E. dulcis was 24.49 ppm (w/w), while the accumulation of Mn in the shoots was 96.83 ppm (w/w). E. dulcis is known to have the potential to increase AMD pH and reduce levels of Fe, Mn and SO42- so that it can meet the quality standards of coal mining activity wastewater. The accumulation of Fe and Mn in the roots and shoots of E. dulcis and on AMD can be used as an effort to monitor the success of AMD phytoremediation on Constructed Wetlands system at WTP Air Laya.

Synthetic insecticides are still extensively used by farmers to control insect pests in carrots. The effects of excessive use of synthetic insecticides can damage agricultural ecosystems. This research aimed to examine Bacillus thuringiensis based bioinsecticide toward arthropods existence in vegetative growth phase of carrots The research was conducted in Pagar Alam City (700 m above sea level) and a relative humidity of 48–99%. The carrot plantations studied were planted in polyculture with mustard greens and sweet corn. This study used a completely randomized design (CRD) with 3 treatments and 9 replications. The treatments were bioinsecticide B. thuringiensis; synthetic insecticide (imidacloprid 200 g/l); and no-insecticide application (control). Agronomic observations were height of carrot and their number of leaves. Arthropods observations were carried out using sweep nets, pitfall traps, and direct visual observation. The results showed there was no significantly different on height of carrot plant and their number of leaves among three applications. Arthropods population in carrot plants treated with B. thuringiensis was lower than those in control carrot plants. In pitfall trap observations, the highest number of arthropod individuals obtained was belong to order Hymenoptera and had a moderate value of the Shannon-Wiener diversity index (H'). In addition, total insect population after application of B. thuringiensis observed using nets, tended to decrease from the second observation onwards. The category of insect diversity level trapped by Pitfall trap in B. thuringiensis bioinsecticide treatment was included in the medium category (H' = 1.75), while the treatment of imidacloprid (H' = 0.85) and control (H' = 0.81) was included in the low category.

Yard-long bean, a favored vegetable known for its taste and nutritional value, holds economic importance. Its climbing nature and environmental resilience make it ideal for urban cultivation in pots and climbing frames. This study, conducted in a limited urban space, aimed to determine optimal pot size and cultivars for yard-long bean cultivation, emphasizing growth and yield. Two pot sizes were used: a larger one (30 cm diameter x 37 cm height, M1) and a smaller one (30 cm diameter x 30 cm height, M2), alongside three commercial cultivars: Kanton Tavi (V1), Camellia (V2), and Arafi (V3). Results indicated that a larger pot size increased pod number and total pod weight per plant, facilitating root development, vine growth, and enhanced yield. The larger substrate volume retained moisture and boosted plant biomass. Cultivar treatment affected branch length and flowering time, with Camellia exhibiting the longest harvest period (14 harvests). Hence, for Camellia varieties, cultivation using larger pots (30 cm diameter x 37 cm height) is recommended.
长豆角是一种以美味和营养价值著称的蔬菜，具有重要的经济价值。它的攀爬特性和环境适应能力使其非常适合在城市中的花盆和攀爬架上栽培。本研究在有限的城市空间内进行，旨在确定栽培长豆角的最佳花盆尺寸和品种，重点关注长势和产量。使用了两种尺寸的花盆：较大的花盆（直径 30 厘米 x 高 37 厘米，M1）和较小的花盆（直径 30 厘米 x 高 30 厘米，M2），以及三种商业栽培品种：Kanton Tavi（V1）、Camellia（V2）和 Arafi（V3）。结果表明，较大的花盆尺寸增加了每株豆荚的数量和总重量，有利于根系发育、藤蔓生长和提高产量。较大的基质容积能保持水分，提高植株生物量。栽培品种处理会影响分枝长度和开花时间，其中山茶花的收获期最长（14 次收获）。因此，对于山茶花品种，建议使用较大的花盆（直径 30 厘米 x 高 37 厘米）进行栽培。

Rice serves as Indonesia's main food source, but inadequate storage conditions can lead to seed deterioration and diminished germination performance. To enhance the viability and vigor of stored seeds, this study explores various priming methods' effects on multiple rice varieties. Employing a completely randomized design (CRD) with two factors, the first factor involves rice varieties (V) categorized by germination ranges: 41–50% (V1 = Toyonishiki, V2 = Yoneshiro), 51–60% (V3 = Jaya, V4 = IR50), 61–70% (V5 = Fortuna, V6 = Sulutan), and 71–80% (V7 = IR 24, V8 = Inpago 5). The second factor is seed priming (P), including control, hydropriming, and osmopriming. Results indicate that priming enhances maximum growth potential, germination percentage, vigor index, growth speed, plumule and radicle length, as well as fresh and dry weight. Hydropriming outperforms osmopriming, particularly in vigor index, growth speed, plumule and radicle length, and dry weight. Priming proves more effective in improving maximum growth potential, germination percentage, vigor index, and growth speed at lower germination percentage ranges (41–60%). The most significant priming-induced increases in radicle length, fresh weight, and dry weight occur in higher germination percentage ranges (61–80%)

Horticultural commodities hold significant economic potential in Indonesia, particularly red chilies, which serve various purposes such as a spicy,traditional spicy, and industrial raw material. This research aims to assess the impact of shoot pruning and planting media composition on the morphology and yield of red chili plants. The study employed a Randomized Factorial Group Desugn (RAKF) with two main treatments : shoot pruning and planting medium composition. Results indicate that pruning shoots at 35 days after planting (P4) enhances the cultivation of red chili plants, as evidenced by improved plant height, earlier flowering, and increased root length. Furthermore, a planting medium composed of soil, cow dung compost, and 2:1:1 husk charcoal (M4) proves to be more beneficial for red chili yield, demonstrated by higher plant height, stem diameter, and root length.

The Indonesian Government's efforts to enhance Human Resource (HR) quality include ensuring adequate food production, purchasing power, access, and nutritional intake. This study aims to assess the impact of single and mixed herbicides on corn plant growth and yield. Employing a Randomized Block Design (RBD) with eight treatments replicated three times, the research was conducted from February to June 2023 at the Farmer's Gar-den. Results indicated that herbicide treatments, particularly those with atrazine + saflufenacil as the active in-gredients, demonstrated the most favorable effects on plant height at 6 WAP and 8 WAP, the number of leaves at 6 WAP, ear length, ear weight, and dry seed weight per plot. The atrazine + saflufenacil herbicide treatment had the best effect on plant height at 6 WAP and 8 WAP, number of leaves at 6 WAP, ear length, ear weight, and dry seed weight per plot.

Swiss chard is a leafy vegetable that is high in nutrients, vitamins, minerals, protein, and antioxidants that are beneficial to human health. Swiss chard. Swiss chard is generally cultivated in the Mediterranean climate, grows well in full sunlight, air temperatures 14-21oC, and can still survive at temperatures close to light frost. The aim of this study to evaluate efficient plant densi-ties in urban limited land area and looking at the response of Swiss chard plant to reduc-ing the intensity of sunligt of 45%, 55% and 80%.in urban tropic area. This research was used 4 different artificial shading i.e 0% (control, shade 45%, shade 55% and shade 80%. Microclimate was measured per each shade for 14 days i.e., air temperatur, soil temperature, air humidity, and soil moisture using a data logger meter. Shade with intensity 80% is proven to reduce air temperate and soil temperature, but also inhibits the growth and development of Swiss chard plants. Population 1plant/pot gives the best growth and yield of Swiss chard per plant, 3 plants/pot increased total fresh weight per cultivation area, thereby maximize the use of limited urban land
