Abstract

The existence of undergrowth has an important role as an ecosystem both from an ecological and economic perspective. However, the composition and diversity of undergrowth in an area depends on the land use system. This research aimed to know the species composition and diversity of undergrowth at forest garden stands. Data collection was carried out with a vegetation survey using nested rectangular plots with a sampling intensity of 1%. The data collected included undergrowth species, the number of individuals for each species, and tree species as components of forest garden stands. Data were analyzed by calculating density, frequency, important value index, and Shannon diversity index. The results showed that the undergrowth that exists under forest garden stands were 38 species dominated by 12 species, namely Acalypha australis, Asystasia gangetica, Clidemia hirta, Starchytarpeta jamaicensis, Mikania micrantha, Peperomia pellucidia, Setaria barbata, Andropogon aciculatus, Alpinia galanga, Diplazium esculentum, Paederia foetida, and Crassocephalum crepidioides. The forest garden stands were composed of 43 tree species dominated by 4 tree species, namely Durio zibethinus, Aleurites moluccana, Myristica fragrans, and Gnetum gnemon. The level of undergrowth diversity was in the medium category with an H value of 1.540, indicating the diverse of undergrowth species.

Abstract

he increasing number of food needs is one of the driving factors for increasing agricultural production, but there are constraints on the availability of land. A polyculture system with corn, beans, and pumpkins, commonly known as the three sisters, can create positive interactions that can enhance the growth and development of each plant. This system has a vast potency to be applied to urban farming inside a grow bag because it does not require ample space, the placement of plants is flexible, and it produces a variety of yields. However, it is necessary to assess the effect of growing space on the growth of maize (Zea mays) cultivated by the three-sister system. This study used a completely randomized design with three treatments and six replications. The treatment consists of three planting spaces with various growing bags (treatment A:75 L, B:100 L, and C:200 L). The results of this study showed that the highest corn productivity was in the largest growing space (treatment C), which weighed 318.40 g/cob, and without husks 246.42 g/cob, but not significantly different from treatment B (grow bag 100 L), which weights 316.20 g/cob and without pods of 240.63 g/cob. This study found that the 100 L grow bag was the optimal growing space for planting corn in containers using the three sisters technique.

Abstract

Gotu kola (Centella asiatica) is a medicinal plant that has potential as an antioxidant and antidiabetic. Its compound is able to protect against diabetic nephropathy through the inhibition of oxidative stress. In terms of increasing drug potency and bioavailability of C. asiatica compounds, nanoparticle technology was used. This study aimed to determine the effect of C. asiatica nanoparticles coated with chitosan on the renal histology profile of complicated diabetic mice using a completely randomized design (CRD) with five treatment groups and five replications. The treatment groups were divided into K- (the experimental animals were not given any treatment), K+ (the experimental animals were induced by STZ), P1 (STZ + C. asiatica nanoparticles 120 mg/kgBW), P2 (STZ + C. asiatica nanoparticles 180 mg/kgBW), P3 (STZ + C. asiatica nanoparticles 240 mg/kgBW). The experimental animal model of complicated diabetes was induced by intraperitoneal STZ at a dose of 40 mg/kgBW for two days and STZ at a dose of 60 mg/kgBW for three days and then left for nine days. The C. asiatica nanoparticle therapy was given for 28 days. The parameters in this study were the results of scoring cell damage in the glomerular and tubular tissues (proximal and distal) of the kidney. The data obtained were tested for normality and homogeneity, then the normal and homogeneous data were tested with one-way ANOVA and further tested with Duncan's test. The statistical analysis results showed that C. asiatica coated with chitosan nanoparticles could reduce the damage to the histological profile of the glomerulus and tubules (proximal and distal) of the kidney of diabetic mice. C. asiatica-coated nanoparticles at a dose of 240 mg/kgBW showed the most optimal reduction in damage to the glomerular and tubular histology profiles.

Abstract

Pteridophytes (ferns) are a fundamental element of tropical rainforests, which provide excellent microhabitats for their development. In addition, the sensitivity of pteridophytes to shifts in microclimate and anthropogenic disturbances makes them excellent environmental bioindicators. The purpose of this study was to determine the diversity and distribution of pteridophytes along the elevational gradient of two well-known hiking trails of Mount Penanggungan, East Java, Indonesia. Using a 10x10 m2 plot and transect line, we examined the composition, species diversity using Shannon-Wiener diversity index (H'), relative abundance, and distribution pattern using Morisita index of dispersion (Id) of ferns along an elevational gradient (700–1500 m above sea level) on the hiking trails of Mount Penanggungan, i.e., Tamiajeng and Kunjorowesi. As many as 14 species from 7 families living in both terrestrial and arboreal types were identified. Species composition along the elevation gradient revealed a pattern of predominating species. The Shannon-Wiener diversity index (H') indicated a moderate level of diversity, where many pteridophytes species are found on the altitude gradient between (700-900 m dpl), and the Morisita index of dispersion (Id) indicated a clustered distribution pattern for most of the species. This pattern of diversity and distribution can be explained by changes in biotic and abiotic factors.

Abstract

The exploration of ectomycorrhizal fungi diversity around the campus could provide insights into the presence and distribution of these symbiotic fungi in the area. This study aimed to observe, identify, and provide information regarding ectomycorrhizal fungi diversity in the IPB University Campus Forest. The sampling sites represent various tree species including forests, parks, and green spaces. The exploration was done using opportunistic sampling method. The obtained basidiomata were examined for macromorphological and micromorphological examination to identify the ectomycorrhizal fungi. The identification results based on the morphological characteristics confirmed our specimens as Inocybe cf. squarrosolutea (Corner & E. Horak) Garrido and Suillus bovinus (L.) Roussel. The Inocybe was characterized by having small to medium-sized, pileus squamules, dry surface, light brown to yellowish cap, lamellae crowded, cylindrical or attenuated stipe towards the apex, clavate basidia, and hemispheric knobs basidiospores. The Suillus was distinguished by having a cap that is convex in shape with a slightly brownish yellow color and the surface texture of the cap is smooth, lamella in the form of pores that are quite large and angular, brownish yellow in color, yellow tubular stipe, clavate basidia, and oval spores. These two macrofungi are new records in the sampling area and I. cf. squarrosolutea could be the new information for Indonesia. Our finding provides valuable information for ecological studies and contributes to the additional data on Indonesian ectomycorrhizal fungi diversity.

Abstract

Lactobacillus plantarum BP102 isolated from garlic bulb tissue has probiotic properties, including producing bacteriocin called plantaricin. This study aimed to detect the gene encoding bacteriocin produced by Lactobacillus plantarum BP102, and to evaluate the bacteriocin activity at each stage of partial purification. After the end of the log phase of L. plantarum BP102 was determined, and the bacteriocin-encoding genes were checked by PCR technique. Partial purification of bacteriocin was elucidated including pH-neutralized cell-free-supernatant (CFS), precipitation using 80% of ammonium sulfate, and dialysis (cut-off 10 kDa), then the bacteriocin activity in every partial purification stage was evaluated. The molecular weight of plantaricin was estimated using SDS-PAGE analysis. Lactobacillus plantarum BP102 harbored the gene encoding plantaricin (pln) biosynthesis, namely plnEF and plnK genes. The activity of crude bacteriocin was inactivated by the presence of proteinase-K enzyme. The protein concentration was gradually decreased along with the purification process. The bacteriocin activity was demonstrated at each step of the purification process (CFS, precipitation, and dialysis) against Bacillus cereus by 9.23 ± 0.20 mm, 7.86 ± 0.15 mm, and 7.6 ± 0.10 mm, respectively; while, Escherichia coli by 10.3 ± 0.55 mm, 7.4 ± 0.1 mm, and 6.86 ± 0.45, respectively. The molecular weight of partially purified bacteriocin BP102 was found to be approximately 15.9 kDa. The overlaid part of the gel showed a slight inhibition against E. coli due to a low protein concentration. This bacteriocin purification process should be further optimized to improve the bacteriocin activity that could be useful for food preservation.

Abstract

Sorghum is a strategic commodity with good nutritional and high antioxidant content that can be used as a source of food, feed, and industrial raw materials. Sorghum is a relatively low and less intensive crop than other staple food crops. Sorghum yield can be increased by establishing plant population through a mulching planting system. The purpose of this study was to determine the yield power of several sorghum genotypes, namely three new superior varieties (Bioguma, Kawali, and Samurai) and three local varieties (Plonco, Hitam Wareng, and Ketan Merah), planted with a plastic mulch planting system. The research was conducted on farmers' land in Karangmojo, Gunungkidul, Daerah Istimewa Yogyakarta, which is a dryland soil type. The experimental design used a randomized complete block design (RCBD) with 5 replications. Observation parameters included growth components and sorghum production. The results showed that sorghum planting with a mulching planting system was able to provide yields for the Bioguma variety of 7.70 tons/ha, Plonco variety of 8.41 tons/ha, Samurai variety of 5.38 tons/ha, Kawali variety of 8.21 tons/ha, Hitam Wareng variety of 3.91 tons/ha, and Ketan Merah variety of 4.00 tons/ha. Based on the results of the study, it was found that the genotypes of local varieties were able to compete with new superior varieties and had the best growth response and yield power in the rainy season planting.
