Abstract

Increasing levels of angiogenic factors such as gamma interferon (Y-IF), tumor necrosis factor-beta (TNF-β), and transforming growth factor-beta (TGF-β) are thought to be the cause of the angiogenesis process in hemangiomas. Endophytic fungi are potential in searching for new drug sources due to their antimicrobial, antifungal, and anticancer compounds. This study aimed to determine the potential and interactions of endophytic fungi as candidates for vascular endothelial growth factor receptor-2 (VEGFR-2) angiogenesis hemangiomas and apply Lipinski's rule of five to differentiate drug-like and non-drug-like molecules and in-line toxicity using in silico test. The research method was molecular docking using several programs, namely Autodock Vina (PyRx), PyMol, and Discovery Studio 2019, and tethering five ligands from the endophytic fungus Trichoderma sp. and Aspergillus sp. with 2 VEGFR-2 target proteins (protein codes were 3VHE and 1Y6A). The best binding affinity of the ligands was tested by Lipinski's rule of five and toxicity test using Toxtree. The results showed that benzyl benzoate is potentially an antiangiogenesis inhibitor for VEGFR-2 protein based on its binding affinity value, which is close to the control ligand value of -8.7 kcal/mol (3VHE) and -7.4 kcal/mol (1Y6A). Therefore, benzyl benzoate, chloromycetin, and 1-hexyl-3-nitrobenzene compounds comply with Lipinski's rule of five. Based on the results of the toxicity test and the parameters of the Kroes TTC decision tree, benzyl benzoate and chloromycetin are categorized as safe compounds for consumption. Keywords: angiogenesis, benzyl benzoate, endophytic fungi, molecular docking, VEGFR-2

Abstract

Organic fertilizers contain complete nutrients needed by plants, such as humic acid and fulvic acid, that can promote plant growth and increase the population of beneficial microbes in the soil. Algae can be an organic fertilizer in extract preparations that can increase plant growth and improve soil composition. The calculated number of microbes from the soil on corn land with the application of algae extracts affects the population of soil microbes both by standard plate count (SPC) and most probable number (MPN) methods. The total number of bacteria by SPC in the control soil was 3.1 × 105 CFU/g, while the total fungus was only 1.7 × 104 CFU/g upon applying 5% algae extract. The most microalgae by MPN in the control ground was estimated to be 2.6 × 104 cells/g. Therefore, the application of algae extract affects the number of soil microbes on corn land compared to control soil. The algae extract reduces the number of bacteria and algae but increases the number of fungi on cornfields. Keywords: algae extracts, cornfields, soil microbes

Abstract

Stomatal distribution and area are related to transpiration rate. This study measured stomatal distribution and area in dicotyledon plants used as ornamental plants. The study used Factorial Completely Randomized Design (CRD) with the main factors were six types of dicotyledon plants and three plant parts (top, middle and bottom). Combination factors were the interaction of plant species and parts. By using the replica method and micrometer, the study used five replications with the measured parameters: the stomatal distribution and area. Data were analyzed using SAS with the Factorial RAL model and continued with the LSD test if the treatments were significant. Correlation coefficients between stomatal distribution and area were calculated to see the relationship between the two. The types and plant parts significantly affected the stomatal distribution, while the stomatal area was influenced by the main and combination factors. Syzygium paniculatum Gaertn had the highest stomatal distribution and was different from other plant types. Meanwhile, lower leaves had the lowest stomatal distribution and differed from the middle and upper. Aerva sanguinolenta Bl had the highest stomatal area (591.05) compared to other plant species. The stomatal area on the plant's upper leaves (272,71) was significantly lower than the middle and lower parts. The combination between species and the lower part of the plant produced the highest stomatal area compared to other combinations. Stomatal distribution was inversely proportional to the stomatal area. Keywords: dicotyledon, part of plant, stomatal area, stomatal distribution

Abstract

Transpiration rate internally depends on the water content that occupies the tissue in the leaves, which is reflected in the thickness of the leaves. This study measured the transpiration rate and leaf thickness of ornamental dicotyledon plants. The experiment used Factorial Completely Randomized Design (CRD) with three replications. Six species of dicotyledon plants and three parts of the plant were the main factors. The interaction between plant species and plant parts was a combination factor. The transpiration rate was measured using a weighing method and leaf thickness was measured from the upper to the lower epidermis. Leaf thickness was measured before and after transpiration rate measurement. Data were analyzed using SAS with Factorial CRD model and continued with the LSD test if there was a significant treatment. The species of plant and plant parts had significant effects on the transpiration rate and leaf thickness, but the combination or interaction of the two did not affect the transpiration rate and leaf thickness. Aerva sanguinolenta Bi. had the highest transpiration rate followed by Syzygium paniculatum Gaertn., Tabernaemontana divaricata (L.) R. Br. ex Roem. & Schult., Excoecaria cochinchinensis Lour., Bougainvillea glabra Choisy, and Codiaeum variegatum (L.) A. Juss while the leaves at the bottom of the plant had the highest transpiration rate compared to the middle and upper parts of the plant. Codiaeum variegatum (L.) A. Juss. had thick leaves and less transpiration rate than the other plants. The leaves at the top had a higher thickness than those at the middle and bottom parts of the plant. This occurs because the transpiration rate of the lower leaf was faster than the upper and middle parts. Leaf thickness was inversely correlated to the rate of transpiration. Keywords: dicotyledon, leaf thickness, transpiration rate

Abstract

The study aimed to determine the effect of mineral status (Ca, P, Fe, Mn, Zn, Cu, and Pb) in soil, grass, and hair of spotted deer in the Bogor Presidential Palace. Fifteen male deer were randomly selected with an age of ± 2.5‒6 years. Soil was collected from ten points representing land, and grass samples were obtained by sampling from several points of the grazing area. Mineral content in soil, grass, and deer hair were analyzed using the atomic absorption spectrophotometry. The results showed that the level of Ca (0.03%) and P (0.016%) in the soil are deficient, Mn (1960 ppm), Zn (33.89 ppm), and Cu (77.23 ppm) are considered in the normal range, and Fe and Pb elements are high. Mineral levels of Ca, P, Cu, and Zn in grasses do not meet the daily requirements, whilst high levels of Fe and Mn minerals exceed the requirements for the spotted deer. The Pb content in grass is 0.94 ppm, which is within the normal limit. The levels of Ca (0.02%), Fe (308.11 ppm). and Mn (6.18 ppm) minerals in deer hair are high, however, zinc (44.68 ppm) and Cu (3.08 ppm) levels are low. High Pb level (14.38 ppm) is due to the long-term impact of Pb accumulation. Keywords: Bogor Palace, mineral status, Axis axis

Abstract

Soil erosion is the main cause of land degradation. Jeneberang watershed is one of the priority watersheds in Indonesia. It has a big problem related to erosion in the upstream area. Jeneberang watershed is important area, its function is as water catchment for Bili-bili reservoir. It is served for flood control, irrigation water sources, water and hydroelectric energy supply. The aims of this study were to analyze the soil erosion prediction based on existing condition; develop an ideal land cover scenario to decrease soil erosion; and suggest land cover planning recommendations based on tolerable soil loss indicators in the upstream of Jeneberang watershed. This study was conducted using map overlay method to determine the value of the erosion factor. Erosion was predicted based on Universal Soil Loss Equation (USLE). Land scenarios and simulations was calculated by estimating the erosion in forest area and spatial planning land cover. The result showed that soil erosion of existing condition was approximately 813.1 tons/ha/year. The tolerable soil loss was only 22.9 tons/ha/year. The landuse scenario that chooses the lowest presumed erosion result is the implementation of spatial planning of Gowa district 2012-2032 with soil conservation technique applied. It can reduce erosion and sediment as 96.6% in upstream Jeneberang watershed. Keywords: erosion, Jeneberang watershed, scenario, landuse

Abstract

Land is one of the main factors in rice production. However, the transfer of agricultural land functions to other sectors continues and becomes a challenge in the food supply in Indonesia. Serang City is one of the rice-producing areas in Banten Province. This study aims to analyze changes in the transfer of rice field functions to other sectors by mapping rice field cover using Sentinel-2 satellite imagery in 2021 compared to 2019 with the Random Forest method by using Google Earth Engine (GEE) applications and cloud computing support. The study results showed that the cover of rice fields in Serang City in 2021 decreased by 602.87 ha (-7.20%) compared to 2019 from the total land cover. Land cover in other vegetation was also reduced by 242 ha (-2.45%), while urban land cover in 2021 increased by 781.82 ha (10.89%). This study shows that there has been a change in land transfer in Serang City due to urban expansion in 3 years, as well as that the use of GEE can streamline monitoring of changes in land transfer and land use cover. Keywords: rice field, Google Earth Engine, Sentinel-2

Abstract

Climate change has a real impact on yields, seasonal shifts, cropping patterns of citrus siam banjar plantations (Citrus suhuensis) on tidal land. This research aims to analyze the relationship of the cropping patterns of surjan systems and climate extremes, as an effort to overcome climate change. The research was conducted in Batola in 2020 using written and oral survey methods. Data was extracted from farmers and related institutions. The respondents consisted of 45 men and 45 women. On each sub-district, 2 villages were surveyed according to tidal land type, namely Marabahan district (SP1 and SP2) type C, Mandastana subdistrict (Karang Indah and Karang Bunga) type B, and Cerbon district (Simpang Nungki and Kambat River) type A. The results showed that the chance of El-Niño was around 16.7-22.7%, while La-Niña reached 40%. The total extreme event was 67.8% of La-Niña side by side with El-Niño 15 times and generally El-Niño precedes La-Niña by about 40%. The total extreme event reached 62.7%. The productivity of citrus observations in 2015-2019 was 1.274 ton/ha and during El-Niño yields decreased by 0.05 ton/ha. Crops damaged by El-Niño in 20152016 were -2% of the area of 6,825.03 ha. More than 90% of farmers during extreme events applied a pattern of superior local-rice oranges-rice to tabukan and oranges-vegetables on mounds. Cropping patterns on tidal tidal land show a high level of resistance to climate change because they have not changed much for decades in both normal, dry, and wet climatic conditions. Keywords: El-Niño, extreme climate, La-Niña, siam banjar oranges, tidal land type A, B dan C

Abstract

Sengon (Falcataria moluccana) cultivations still have to face threats from plant diseases. Diseases can be found in nurseries and plantation. Biological agents can be used to control various types of plant diseases and have various advantages. The use of biological agents in forestry plantations must consider the aspects of effectiveness and efficiency. This study aims to examine the effect of various treatment of control technology packages on the incidence of major diseases, and to determine the financial feasibility of various disease control technology packages for sengon in nurseries. The research was conducted through interviews to explore cultivation techniques and production costs. In addition, experiments were carried out on the application of various disease control strategies using commercial formulations of biological agents. The commercial formulations of biological agents used were Rhizomax, Primagrain, Trichowish, Kayabio, Bio-Hara Plus, and fungicide Dithane M-45 80 WP. There were two treatment packages of new technology that have an effect on increasing the growth of sengon at the beginning of growth stage, namely P1 (BioHara Plus and KayaBio) and P2 (Rhizomax and Primagrain) treatments. All treatments of the new technology package had no significant effect on increasing the survival rate and suppressing the incidence and severity of disease in sengon seedlings. All new technology package treatments can generate profits even though the value is smaller when compared to existing technology treatments. All the new technology package treatments have an R/C ratio of more than 1 so that they are feasible to be applied by farmers. Keywords: biological control, feasibility, plant diseases, nurseries, Falcataria moluccana
