Abstract
Marginal land conditions are a major problem in reducing the level of diversity of species due to decreased soil, climate, and water quality and topography. This study aims to analyze the diversity index and the dominance of fruit tree species cultivated by surrounding communities. The research method uses nested sampling in 4 (four) sub-districts, each of which is taken three sample villages and each of them is made of three transect plots measuring sample plots 20 × 20 m 2 (trees), 10 × 10 m 2 (poles), and 5×5m 2 (sapling). Data analysis using the Biodiversity R application program with version R 3.6.1. The results of the analysis of the growth rates of the best tree species were found in Ploso Regency because they had the highest growth rates of trees, poles, and saplings. The diversity of fruit tree species is based on the distribution of the highest H index value of 1.47 and the lowest of 0.58 and includes areas that have an abundance of moderate species. Fruit tree species that have the highest importance value index are Mangifera indica (mango) 70.26% with a tree density of 139 individuals per hectare, then Dimocarpus longan (longan) 40.24% with a tree density of 153 individuals per hectare. The results of this study indicate that the community structure of fruit trees in degraded lands is more dominated by plants from the Sapindaceae and Anacardiaceae families which generally grow spread in the 4 sub-districts studied.

Abstract
This study aimed to determine the antixenosis of soybean genotypes and the resistance to pod borer. 16 successful lines of soybean were used. Planting dates were arranged in a way to integrate the flowering period of 16 promising lines of soybean. For two days, a pair of four-day adult pod borers were infested in each plant at the R4 stage. The result revealed that the difference in soybean promising lines had a major impact on the population of egg and larva, and on the pod damage severity. The lowest egg (1 egg/plant) was identified in Grb/Myp-16 and GH-Gn-8, while the lowest larval population (1 individual/plant) was in GH-Gn-8. The lowest impaired pod intensity was found on Grb/Myp-16 and Brg/Myp-13. The weight of the seed ranged from 2.4 to 6.5 g/plant. The trichome density ranged from 28.3-72/mm 2 with three different positions (leaning, skewed and upright). In summary, four soybean promising lines were consistently resistant to pod borer, Brg/Myp-13, Grb/Myp-16, GH-Gn-8, and GH/KR-13. The resistance was antixenosis or non-preference as both a place to lay eggs so as a feed. These lines had the possibility as a genetic source to improve resistance to Etiella zinckenella.

Abstract
This study aimed to determine the environmental management model in coastal areas based on ecosystems; Pesantren Al-Khairat in Central Sulawesi, Case Study. Optimizing environmental conservation is done through many factors, and religious elements become one of these factors; religion becomes a way to shape the character of its adherents in protecting their environment. Islam as a religion has teachings that direct its supporters to protect the environment adequately so that the instructions are in harmony with the concept of environmental conservation. This research uses ecopesantren theory with several indicators. First, the pesantren policy that carries out environmental management by utilizing land to create artificial forests. Utilization is based on an agroforestry, agrosilvopasteur and agrofishery approach. The zone of mangrove forest utilization can help food security and environmental preservation in the Pesantren environment. The existence of an artificial lake as a water catchment area supports efforts to conserve water in Pesantren. Also serves as a water reserve through rainwater collection so that it can minimize the occurrence of flooding. Second, participatory activity-based environmental development policies. Pesantren make santri as an aid team in overcoming natural disasters and ecological disasters to minimize environmental damage, social impacts, and economic losses. The environmental management model carried out by the Pesantren Al-Khairat in Palu in the coastal area and geographically crossed by the equator, can reduce environmental damage and can be used as a role model in disaster mitigation and eco-implementation implementation.
In-silico study of Marselia crenata compounds as activator Keap1/Nrf2 pathway in ovarian function

Published: May 2021

AbstractThe activity of granulosa cells during folliculogenesis and the presence of follicular atresia causes increased ROS (Reactive Oxygen spesies) level in the ovaries. ROS accumulation will induce disorders of ovarian physiology, so maintaining ROS levels is necessary for normal ovarian physiology. Nrf2 (nuclear factor erythroid-2-related factor 2) is a protein that plays a role in regulating the expression of genes that induce antioxidant expression. In an inactive, Nrf2 binds to Keap1 in the cytoplasm. Inhibiting the interaction of Keap1-Nrf2 will activate Nrf2 and Nrf2 will move towards the nucleus to regulate some endogenous antioxidants. The research aims to investigate the potential ofMarsilea crenatacompounds as inhibitors of Keap1-Nrf2 interactions. The study used an in-silico approach. Compounds chosen were Naringenin and Hyperosida. Keap1 (ID: 2flu) was obtained from Protein Data Bank (PDB), while Hyperoside (CID: 5281643), and Naringenin (CID: 932) were retrieved from PubChem database. Keap1 was prepared by removing any solvents and other ligands using Discovery Studio v.19 versions. Naringenin and Hyperoside were minimized their affinity using PyRx 0.8 software. Ligand and protein were interacted using autodock vina integrated with PyRx 0.8 tools and visualized by Discovery Studio v.19. Results showed that Naringenin and Hyperoside bound to Keap1 in the same active sites of Keap1- Nrf2 regions. Both of Naringenin and Hyperoside interacted with Keap1 in different areas. The interaction between Keap1 and ligands (Naringenin and Hyperoside) was through the formation of hydrogen bonds and Van der walls forces. The binding energy of Naringenin and Hyperoside with Keap1 was -6.7 and -7.2 Kcal/mol, respectively. Our study predicted that Naringenin and Hyperoside might have a potential activity to inhibit Keap1-Nrf2 interaction and activated Nrf2 to regulate the antioxidant gene.

Abstract
Eggplants (Solanum melongena L) is a vegetable that people like. Provision of nutrients through leaves and organic hormones which are sustainable materials are expected to increase the productivity potential of eggplant plants. This is caused by the synergy of the application of leaf fertilizer and plant growth hormone. The study was conducted at the Krian District Counselling Centre using a polybag with Factorial Complete Randomized Design repeated three times. Factor I: Leaf Fertility Concentration with 4 treatment levels (G0 = 0g/l water; G1 = 1 g/l water; G2 = 2 g/l water; and G3 = 3 g/l water). Factor II: ZPT concentrations with 4 levels of treatment (Z0 = 0 cc/l water; Z1 = 1 cc/l water; G2 = 2 cc/l water; and G3 = 3 cc/l water). There is a synergy between the application of leaf fertilizer and ZPT on fruit quality with the best application in leaf fertilizer concentrations of 1cc/l and ZPT 2cc/l, where the potential diameter of the fruit increases by 15% and the length of the fruit increases by 28%. The highest potential for vegetative growth is in the application of 1g/l leaf fertilizer where the potential for production increases with 1g/l fertilizer application and 2cc/l hormone administration. The application of leaf fertilizer and hormones gives an increase in yield compared to control where the application of leaf fertilizer increases the potential for growth by 16% and increases the fruit production potential by 66%. In addition, the application of the 2 cc/l hormone can increase growth potential by 6% and increase fruit production potential by 69%.

Abstract
The cotton development program in Indonesia is prioritized to support the national textile industry. Program on Cotton Intensification for Smallholders (IKR) began in 1978/1979 with cotton planted area 15-22 ha and using introduced cotton varieties. The fiber quality of these introduced varieties was appropriate for the raw materials of the textile industry. However, the introduced varieties were not following the Indonesian agroecosystem, especially their resistance to the main cotton pest, namely cotton planthopper, Amrasca biguttulla Ishida. The purpose of this review is to study the development of Indonesian cotton varieties and their use as raw materials in the textile industry. The development of Indonesian cotton varieties began in 1985 oriented to the varieties with characters on high productivity and resistance to cotton planthopper. In the development of the Indonesian National Cotton (Kanesia) variety, there was an increase in production potential and fiber quality, so that it affected its use in the textile industry. From 1990 to 1998, cotton varieties Kanesia 1 - Kanesia 7 were released with high productivity character orientation, namely 350-902.4 kg fiber/ha and relatively resistant to cotton planthopper with a fiber length of 27.78-31.75 mm (fiber category: medium-long). In 2003 Kanesia 8 and Kanesia 9 were released by improving the character of production and fiber content, id., 650.8-962.2 kg fiber/ha, with fiber lengths of 29.2-30.3 mm (fiber category: medium-long). In 2007 6 new superior varieties were released, namely Kanesia 10 - Kanesia 15 with improved character production potential (586,5-1,178.8 kg fiber/ha), as well as drought-resistant characters for Kanesia 14 and Kanesia 15, fiber length 26,92-29.97 mm (fiber category: medium-long). In 2014, 5 varieties Kanesia 16 - Agri Kanesia 20 were released with improvements to the character of production potential, namely 478.4-1,616.3 kg fiber/ha, and also improvement in fiber quality for the character of strength, elasticity, and smoothness of fiber, with fiber length, 28.7-29.6 mm (medium fiber category). Kanesia 21 - Kanesia 23 were released in 2017 with improvements to the character of production potential, namely 726.1-1,420.3 kg of fiber/ha and improvement in the character of fiber elasticity. Fiber quality is the main character for determining the use of cotton fiber to be processed into yarn (yarn) and the subsequent process to become textile.

Published: May 2021

Abstract
Water with hydrogen content is a source of renewable fuels that are available in abundance. However, the main constraint of the process of water splitting or hydrolysis is the amount of energy needed in the process. Photocatalysis material is a material that can function as a catalyst that helps the water-splitting process. The characteristics of photocatalytic material are mainly determined by the energy gap or bandgap that will allow the excitation of electrons and holes. This paper will discuss the literature review on the development of ZnO and TiO2 semiconductors as photocatalysis materials.

Published: May 2021

Abstract

Cecropia peltata is an invasive species which was initially introduced through Kebun Raya Bogor. Research on the presence of C. peltata and its effect on plant community are still limited and most were based on above ground vegetation observation. Information on seed storage in the soil is important for understanding the impact of plant invasion on an ecosystem. Aim of this tudy is to discover and analyze the impact of C. peltata in the soil seed bank of Kapur limestone hills. Seedling emergence and seed extraction was used for a method. The result showed 646 seedlings of C. peltata in the soil seed bank with seedling density approximately 23.07 ± 33.59 seedlings tray -1. The presence of large amounts of C. peltata in the soil seed bank has the potential to push the dominance of this species on the above vegetation which can subsequently cause loss of native species and habitat destruction.

Published: May 2021

Abstract
Water treatment of domestic wastewater/greywater to be reused and safe for environment are needed. In addition, bearing in mind that the need for water sources for the community is getting scarce, especially in dry season. Greywater treatment can be done naturally by using plants or known as phytoremediation. With this natural process, the operational costs for treating greywater is cheap. The potential of plants diversity in the Purwodadi Botanic Garden as a wastewater treatment in wetland model can be used as an education tool for visitors and has aesthetic value. The aim of this study was to provide a phytoremediation model for greywater treatment in the Purwodadi Botanic Garden. The method used wasdescriptive (quantitative and qualitative). Data collection was done through obtaining documents, conducting interviews, sampling and laboratory analysisof wastewater quality with parameters stated in Permen LHK 68/2016. The pond as a phytoremediation model in constructed wetland / floating wetland (CW / FW) functions as a propagation of aquatic plants, surface water and greywater treatment, educational facilities, and also recreation facilities. The developed pond is divided into three segments: Zone 1 pre-processing (inlet); Zone 2 processing (CW / FW) and Zone 3 post processing (outlet). The development of zone 3 can enhance the beauty of the landscape while ensuring the diversity of the biological community, as well as other tertiary treatment processing systems.

Authors: Mastuti R , Rosyidah M 
Published: May 2021

Abstract
Plants are a main source of various types of secondary compounds. Plant secondary compounds play a greater role in interacting with the environment than contributing to the growth and development. Therefore, different environmental conditions besides influencing growth can also affect the profile and concentration of secondary compounds. Ciplukan (Physalis angulata L.) has been known as medicinal plants. The medicinal properties are derived from bioactive secondary compounds especially withanolide and physalin. This study aims to identify the diversity of secondary metabolites found in in vitro callus and plants tissue of ciplukan. Withanolide and physalin profiles of callus tissues, cotyledonary shoot-derived plantlet and germinated seeds-derived plant, were evaluated by LC-MS analysis. The LC-MS analysis of methanol extract showed the diversity in the amount and type of withanolide and physalins. This study confirmed that in undifferentiated callus cultures and in vitro induced plantlet of P. angulata the biosynthesis activity was not altered and the accumulation sites of withanolides were not missing. However in vitro regenerated plant produced withanolides and physalins in higher number. Therefore, modification of plant cell culture system to improve withanolide including physalin production of P. angulata is a good future prospect.
