The island of Java is Indonesia’s largest rice production. However, the conversion of land into industrial areas and construction projects has contributed to the decline of rice production on the island. Therefore, it is necessary for the country to expand its agricultural site outside of Java island through the utilization of swampland. Indonesia has large areas of swampland, which have not made the most of it. The swampland farmers have never grown high quality of rice. Thus, the selection of high-quality rice is considered to increase rice production in the swampland. This article aims to discuss the rice cultivation of superior variety in the swamp to improve national food security. The result of this research showed that local farmers in the swamp area rarely adopt high-quality rice. In fact, local rice variety has low productivity and longer lifespan. Therefore, the use of the superior quality of rice is expected to boost rice production. Nevertheless, the Government of Indonesia has developed numbers of high-quality rice such as Inpara and Inpari , which are more adaptive in the swampland. The Inpara is more resistant to standing water for tidal swamps, while the Inpari is more suitable in lebak swamps (most of the year inundation). The use of Inpara and Inpari in swampland can increase rice production. The implications of rice cultivation of superior varieties increased productivity and crop index due to shorter rice life, resistance to pest and disease attacks, and tolerance of marginal environmental conditions. The use of superior variety can increase rice production, thus support food security in Indonesia.

COVID-19 pandemic has significantly impacted every part of human life, both economic and non-economic, including agriculture. As a country where many people still rely on agriculture, Indonesia faces a complicated situation if the pandemic continues because food production will be affected. Indonesia announced its first COVID-19 case in March 2020; in response to this, the government applied limitations on economic and non-economic activities. These actions slowed the commercial and industrial sectors, and many people lost their jobs, with middleand low-income citizens being the hardest hit. The situation presents a high risk for food security due to the decrease in purchasing power and food supply chains not being able to run normally. This study aims to arrange food security strategies post-COVID-19 pandemic. This paper presents, to overcome the food-security issue after COVID-19 in Indonesia, emergency strategies such as controlling food price and providing subsidies for farmer are needed. And long term strategies such as making the food supply chain more effective and increasing food diversification also required. All people and parties need to participate in every relief program for any program to fight the COVID-19 pandemic to succeed.

Lactobacillus plantarum , a lactic acid bacterium, produces organic acids, fatty acids, ammonia, hydrogen peroxide, diacetyl, and bacteriocin to survive in an unfavorable environment. Plantaricin, a class II bacteriocin produced by L. plantarum, is reported to be heterologous, and its ability to inhibit or kill pathogenic bacteria is very broad, with potential application as a bio-preservative. Plantaricin production is regulated by genetically organized operons, which also encode structural genes, immunity proteins, and secretion genes in plasmids or chromosomes. The mechanism of action against pathogenic bacteria depends on the characteristics of plantaricin. The most common bactericidal mechanisms are disruption of the cell wall integrity and inhibition of protein or nucleic acid synthesis. This review focuses on characterization of the heterologous mechanisms of plantaricin to inhibit and kill pathogenic bacteria and the future role of plantaricin for food preservation. With this review, we hope to contribute to innovation in food preservation, by promoting a better understanding of this natural resource.

Sarcopenia is a degenerative phenomenon, common in elderly populations. As humans age, they are likely to experience skeletal muscle weakness and atrophy; however, unfortunately, there is still no effective treatment for sarcopenia. The health-promoting potential of plant-based foods is associated with the presence of bioactive components. This article reviews information on bioactive plant compounds which may affect skeletal muscle health, particularly with respect to therapeutic approaches to sarcopenia. In general, plant products can be categorized into two main groups, based on their general status in the human diet: inedible or edible. Investigations suggest that bioactive compounds from both groups show the potential to prevent the development of sarcopenia, in several ways, including anti-atrophy, prevention of oxidative damage, enhanced myogenesis, and anti-inflammatory activity. Each of these agents has been shown to suppress one or more of the signs of sarcopenia, and restore health to muscle, in the patient ( in vivo ) or in tissue culture ( in vitro ). The potential use of plant bioactive compounds as therapy for sarcopenia is worthy of further study.

Monitoring photosynthesis is a fundamental process to improve the yield and quality of plants in a greenhouse. The CO 2 balance method is often employed to predict the photosynthetic rate of plants. We reviewed the essential parameters for predicting photosynthetic rates of plants canopy in greenhouses using the CO 2 balance method. Even in a naturally ventilated greenhouse, ventilation rate is an essential parameter for the CO 2 balance method, but it must be measured in real time as it fluctuates with weather conditions. We studied three types of ventilation rates (the tracer gas, heat balance, and water vapor balance methods). Comparing the measuring techniques of ventilation rate provided us an understanding of the strengths and weaknesses of each method. This knowledge can guide us to choosing the best method based on accuracy, device usage, practicality, and the installation budget. Most researchers have measured and controlled CO 2 concentrations in a greenhouse using an infrared gas analyzer and predicted the ventilation rates using the tracer gas method. This method is suitable for the measurement of low and closed ventilation. The estimated ventilation rate by the heat balance method is recommended for large ventilation openings. The water vapor balance method is sufficient for measuring the ventilation rate when there is a large quantity of water vapor due to plant transpiration. The reliability of this method depends on the accuracy of short-term transpiration measurements. Improved water vapor balance techniques can benefit various greenhouse applications with different ventilator configurations, owing to the flexibility and ease of use compared to those of other methods.

The present article can be regarded as a compilation of various aspects related to the cultivation and utilization of Jatropha curcas in degraded lands, which may not be very suitable for other crops. The benefits of this plant are not limited to producing biodiesel, but expand to biogas and biobriquettes. So, all three phases of fuel (liquid, gas, solid) are possible outcomes from it. Aside from fuels, the byproduct seedcake resulting from pressing the seeds can be used as a good organic fertilizer that is comparable or even better than chicken manure. After detoxification, this seedcake can be valuable feed for livestock. Along with the positive expectations, the study is balanced by also addressing negative expectations when planting Jatropha curcas for commercial applications. A seeds sample of this plant was successfully germinated in indoor condition, after applying the shell cracking pre-treatment. Special attention is paid to the Sultanate of Oman as a country whose geographic location and vast desert lands may encourage large-scale investment in Jatropha curcas for boosting and diversifying the economy.

Rice is an important source of food worldwide. However, the growth of weeds in paddy fields pose a major biological threat to higher rice productivity and quality. Various cultural, chemical, biological, and physical practices affect the growth and composition of weeds in paddy fields. In general, weeds can be effectively controlled through herbicides although the use of chemical-based weed control measures do not provide sustainable solution for the long term. This review highlights the different weed types and their effects on rice production as well as weed management methods that can be used to control the growth of weeds in rice fields. The major points are as follows: (1) there are several types of weeds found in rice (i.e., grassy, sedges and broad leaf), (2) weeds contribute to the rice crop losses and (3) there are a few methods applied for weed control. This review has found that it was beneficial to use biological method instead of using herbicide to control the weeds. This paper can contribute to the knowledge for increasing crop production and sustainable weed management.

Pythium species are soil-borne pathogens which can cause serious economic loss worldwide and threatening agricultural production. Traditional management methods like chemical fungicides are effective against Pythium spp. But as people pay more attention to human health and environmental issues, alternative methods that are ecofriendly and harmless to health are urgently needed. Currently, various approaches had been made including using natural extract, regulating planting conditions, using plant growthpromoting rhizobacteria and screening disease tolerance plants. Hereby, we review the recent achievements, particularly chemical and physical methods, biocontrol and host plant defense which can be used to control Pythium disease.

Cyanide is a toxic substance that can be lethal to humans and is present in nature in several superior plants, called cyanogenic plants, with the capacity to generate significant amounts of cyanide (CN) from the cyanogenic glycosides (GCs) present in a natural state. Among the most important GCs are linamarin, lotraustralin, dhurrin and amygdalin. Cassava, sorghum, almonds, apricots, peaches, apples, cherries, alfalfa, bamboo, among others, are examples of these plants. The potential to generate CN varies with each plant. This paper reviews the literature related to the amounts of cyanide produced by these plants, their effects on humans, as well as their toxicological implications.

In plant-symbiotic bacteria, such as some mehylotrophic bacteria and rhizobia, a novel type of pyrroloquinoline quinone (PQQ)-dependent methanol dehydrogenase (MDH) was recently identified. This MDH, named XoxF encoded by the xox cluster, requires lanthanide (Ln) as a cofactor. Moreover, there is steady indication that these plant symbiotic bacteria strains possess some Ln-dependent cell functions: the strains are able to recognize Ln species under growth conditions, to uptake Ln species into the cell, and to regulate their Ln-dependent methanol metabolisms based on the particular Ln species present. In this review, we focus on the molecular mechanisms involved in Ln-dependent methanol metabolism and Ln-utilizing systems in the plant-symbiotic bacteria, and discuss the physiological roles of these Ln-dependent systems for the plant-symbiotic bacteria in the phyllosphere and rhizosphere.
