Abstract

The utilization of backyard gardens to fulfill family food by the Indonesian people needs to be developed, along with fulfilling nutrition during the Covid-19 pandemic. One of the plants that have the potential to grow is Brazilian spinach (Alternanthera sissoo). References on the morphology of Brazilian spinach are still limited, so it is necessary to observe the plant organs. This study aims to determine the leaf morphology of Brazilian spinach as vegetables in backyard gardens. Morphological observations of these spinach leaves were carried out visually at the Integrated Laboratory of the Agroecotechnology Department, Faculty of Agriculture, Lambung Mangkurat University, in August 2020. The results showed that Brazilian spinach has a herbaceous with a simple leaf in a deltoid shape (deltoideus). It has tapered leaf tips (acuminatus); acuminated leaf base (acuminatus); wavy leaf margin (repandus); and simple palmate leaf venation (palminervis). The arrangement of its leaves is folia decussate, where each nod has two leaves that emerge opposite each other

Abstract

Simawang village has been experiencing a drought since the 2000s due to the uncertainty of the seasonal pattern. All paddy fields in the village depend on rain for irrigation. Consequently, the activities of paddy farming were also disrupted. Some farmers leave their rice fields unplanted, and there is approximately 60 ha of rice fields in Simawang village have turned into abandoned land. In 2014 the farmers started to plant citronella grass on that abandoned land, and in 2017 they already had a citronella oil distiller. This paper discusses the financial feasibility of citronella grass farming and processing and analyzes the farmers' response to those activities. The research found that citronella grass farming and processing in Simawang village is feasible to be implemented. It can be seen from the NPV, IRR, and B/C ratio values of Rp. 218.438.869, 33,2% and 2,1 respectively. Moreover, the farming and processing payback period is two years and 11 months. The cognitive and affective responses of the farmers to farming and processing are good; meanwhile, the conative response is poor. Despite the farmers having good knowledge about farming and processing citronella grass and agreeing that those activities could benefit them both economically and environmentally, most of them have not yet practiced the activities due to land ownership issues.

Abstract

Sustainable development describes the simultaneous maintenance of balance between socio-economic development and environmental sustainability without jeopardizing the future generation's potential to serve their own needs. The main aim of this article is to analyze the sustainability attained by government schools in Andhra Pradesh by providing education to elementary pupils during COVID-19. The unexpected outbreak of the deadly virus COVID-19 wreaked havoc on educational systems, harming children's education. In response to the lockdown, all educational institutions were closed for an extended length of time and remained shuttered even today. According to the information gathered, the government of Andhra Pradesh took all necessary safety measures to ensure the accessibility of government elementary schools and to minimize primary school dropouts. They televised the online lessons to every class at periodic intervals on regional government channels for students. Pupils were given worksheets to exercise according to the curriculum aired on television. These worksheets were submitted for review to the concerned faculty by students' parents. The children were given dry rations monthly as part of the "Mid-Day-Meal" program, which offered healthy meals to address the students' food difficulties, food security, and access to schooling during the COVID-19 epidemic. This document serves as a resource for teachers, administrators, and government officials on how to deal with and avoid the trajectories that primary school pupils face in the future when confronted with difficult situations. Furthermore, the whole perspective provides a list of resources, recommendations, and strategies for ensuring the sustainability of the educational system during the pandemic

Abstract

Comprehensive assessment of the Food security situation, analyses of its trends, and early projections are not simple tasks and, therefore, require the application of a well-developed methodological framework and tools. The present article is dedicated to the Food security assessment framework in Armenia, identification of shortfalls in its methodology, and drawing practical recommendations for improvement. In general, Food security assessment in Armenia is based on methodological guidelines provided by UN FAO. However, there is room to improve adaptation in some areas, address local specifics and needs, and enlarge applied tools. Particularly, we discuss the following potential directions for further improvements: 1) synchronization of existing statistical systems and introduction of mutual verification and adjustment mechanisms, 2) adjustments in the calculation of food consumption volumes and food self-sufficiency data, 3) introduction of new aggregated and integral indicators for reflecting different aspects of the Food security situation and 4) improve timelines for data availability, especially period of summarizing and publication of Living Conditions Survey results. It should be noted that, although the discussion is based on the methodology of Food security assessment in Armenia, the issues raised relate to many developing countries around the world, which mostly use the same methodological framework.

Abstract

Among the many preserved mangrove areas in Riau Province is the one located in the Meranti Islands Regency. However, the regency is prone to environmental pollution and destruction, so control efforts, namely prevention, management, and recovery, are needed to mitigate it. This study aims to explain women's involvement in the mangrove community's activities as well as their social position within said community. Their involvement will be able to explain their social position, whether they have the ability to make decisions on public activities or only act as objects of a patriarchal development process. This study uses a descriptive qualitative approach. The main informants in this study were women who were directly involved in the mangrove community activities, while the villagers who were not directly involved acted as supporting informants. The village women who were involved in the mangrove forest rehabilitation are all married, aged 29 to 50 years old, and have completed elementary school. Each woman has specialized activities, such as seeding, planting, and making dodol, syrup, and chips. Their role in the mangrove community has a great potential to control the balance between ecological and socio-economic benefits of mangrove forests. However, their activities are not independent. Their involvement is passive as it remains under the management of a coastal conservation leader, and it only serves to help their husbands because the rehabilitation of coastal areas will help maintain the habitat of fish and marine animals, which are their husbands' source of income.

Abstract

The phenolic compound is the main source of antioxidants that reduces the incidence of chronic diseases such as heart disease, blood cholesterol, blood pressure, diabetes, etc. This experiment aimed to investigate the effect of the three milling processes of rice (dehusking, auto, and polishing) on polyphenol content with their antioxidant activity and nutritional profile. The polyphenol content was determined according to the Folin Ciocalteu method. Polishing rice contained a maximum phenolic compound (36.28 ± 0.73mg/g of extract) that was statistically different from other milling rice (p<0.05). Polishing rice contained the highest amount of protein (262.69 ± 0.38mg/g extract), whereas auto rice contained the highest amount of free amino acid content (14.06 ± 0.46mg/g extract) and total sugar content (1312.29 ± 2.28mg/g extract). Reducing sugar content was statistically similar to all milling rice. Antioxidant activity was comparatively assessed by ABTS (2, 2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid) free radical decolorization assay method. It was investigated that polishing rice showed strong free radical scavenging capacity by ABTS radical. It is concluded that polishing rice can be used as a functional ingredient with high polyphenol and protein content with strong antioxidant activity.

Abstract

The research was conducted to assess the satisfaction of tourists with local community-based tourism services in the My Hoa Hung (MHH) commune in Long Xuyen, An Giang, Vietnam. The research findings will be the scientific and practical basis for effective and sustainable tourism development in MHH. A mixed-method of qualitative and quantitative is used in this study. Tourist local officers and tourist providers were interviewed as key informants. Such samples of domestic and foreign tourists were interviewed using a questionnaire survey to collect and analyze the tourists' satisfaction with tourism services. The result shows that tourists visiting MHH come from different regions and countries, from different age groups, and occupations, so their needs and satisfaction with MHH's community-based tourism services are also very diverse. The study uncovers that tourists are most satisfied with the human factor, especially the enthusiasm attitude of the tourist service provider (reaching 4.07 points), and then environmental landscape (3.90 points), infrastructure (3.90 points), price (3.80 points), and the lowest security- safety factor (3.73 points). However, in each factor, there are still a number of criteria that tourists are not satisfied with, which should be paid attention to for sustainable tourism development, such as environmental sanitation, traffic safety, and English communication ability of tourists' service providers.

Abstract

Latex diagnosis was introduced to monitor plant physiological status. In this study, we observed the effect of tapping system alteration in 2019 and 2020 on the latex physiological status. Latex samples were collected from 26 blocks of 10 rubber estates in North Sumatra Province, Indonesia. The physiological parameters assessed were totally solid, sucrose, inorganic phosphorus, and thiol contents. Our observation showed that the tapping system change did not significantly affect the total solid content. In terms of sucrose content, a significant effect was detected only in tapping change from quarter spiral upward tapping d3 to d4 (7.80 mM and 2.30 mM, respectively). While, inorganic phosphorus content decreased in all tapping system alterations, suggesting a metabolic response to tapping system adjustment. According to sucrose and inorganic phosphorus contents, yield optimization could be implemented in appropriate blocks. The thiols content was not significantly affected by tapping system alteration. The RSH values ranged from 0.32 mM to 0.76 mM, suggesting a wide variation in the antioxidant level of the plant. While sucrose and thiols content showed some discrepancies to the LD theory, Pi content exhibited a dependable response, suggesting that this parameter could be a good indicator to evaluate the tapping system regime. Our result could be a beneficial input for rubber planters to maintain the physiological level to the commercial extent.

Abstract

Zein-based biomaterials were used as alternatives to plastic to produce spray-on mulching films and horticulture pots. Spray-on zein-based mulching films were prepared using basic zein solutions in water solidified with either potassium salts or acetic acid. In the lab, zein mulching films decreased moisture loss by approximately 10% over a 16 days period, reduced phosphorus runoff by 70%, and prevented soil erosion upon exposure to simulated rainfall events. Healthy growth of cherry radishes and pickling cucumbers was observed with zein mulch solidified with potassium phosphate and glacial acetic acid, indicating that zein mulch is a promising alternative to plastic mulching films. Moreover, zein was used to produce horticulture pots in combination with either linseed or tung oil. Zein pots did not degrade upon exposure to either -18℃ for seven days or outdoor sun for seven days or when they were submerged in aqueous solutions at pH 4, 6, and 9. Food grade dyes were incorporated into the potting material to enhance visual appeal without affecting the integrity of the zein material. Heirloom radish seeds germinated in zein pots were taller compared to those grown in commercial peat pots, indicating that zein pots can be successfully used
