Abstract

Pemanfaatan Azotobacter dan Azospirillum sebagai mikroba fiksasi N2 dapat menjadi solusi dalam mengurangi penggunaan pupuk N anorganik. Inokulasi mikroba fiksasi N2 tersebut memerlukan isolat yang unggul dalam fiksasi N2 dan viabilitasnya tinggi. Sebuah percobaan penjaringan Azotobacter sp dan Azospirillum sp untuk mendapatkan isolat yang unggul dalam menambat N2 dan  tinggi viabilitasnya pada lahan sawah telah dilakukan di Laboratorium Biologi dan Bioteknologi tanah, Fakultas Pertanian, Universitas Padjadjaran. Isolat diambil dari rizosfir dan padi akar di Sukatani dan Karangbahagia - Bekasi, Rengsdengklok - Karawang, Jatinangor - Sumedang  dan Ciparay - Bandung. Hasil penelitian didapat isolat bakteri yang unggul dalam fiksasi N2 dan viabilitasnya yaitu Azotobacter chroococcum dari rizosfir padi sawah varietas ciherang di Rengasdengklok-Karawang dan Azospirillum irakense dari akar padi sawah varietas ciherang di Ciparay-Bandung. Kata kunci : Azospirillum sp, Azotobacter sp, pupuk hayati, penambat N, sawah

Abstract

The rapid development of settlements, industry and infrastructure in the city of Bekasi has resulted in increased pollution, reduced the amount of agricultural land used as a food producer and a source of oxygen. To minimize this impact, it is necessary to have community service in the form of urban farming activities using the green wall method. The method of implementation is in the form of outreach and training, such as (1) Providing knowledge and understanding regarding urban farming and procedures for making green walls, (2) Carrying out green wall making practices. The results of its activities are the presentation of the extension material which includes the history of green walls in the world, types of green wall, the main structure of green wall, green wall containers, green wall planting media, types of plants for green wall, watering techniques on green walls, the concept of laying out green wall, and practice of making green wall (tools and materials, as well as work steps). Furthermore, the practice of making green wall (done outdoors). At the practical stage, the community is invited to be directly involved in assembling materials and arranging plants on the media so that a green wall is formed. This green wall creation program is very useful, gives satisfaction, and the program can be continued independently by partners.

Abstract

The enthusiasm for maintaining health has increased in line with the Covid-19 pandemic, though they have to pay the higher price. Therefore, study aims to determine changes in people's behavior in consuming organic vegetables due to Covid-19, willingness to pay (WTP) and factors that influence. The research was conducted in three stages--descriptive socio-demographic factors, calculation of WTP with the Contingent Valuation Method approach and SEM (Structural Equation Modeling) analysis. Based on 155 respondents who determined by Slovin formula and accidental sampling technique. The study showed that consumers had a higher WTP for various types of organic vegetables, especially spinach, chayote, and kale. However, this WTP is significantly influenced by level of education, type of work and income. Consumer behavior significantly affected WTP for organic vegetables during Covid-19 pandemic. Thus, Covid-19 pandemic provides great potential for an increase in the number of consumption and purchases of organic vegetables.

Abstract

Production of liquid biofertilizer Azotobacter requires pure inoculum with N2 fixation capacity, hormone production, and optimal cell density.   This research was conducted to determine the effect of Fe-Mo microelement and Azotobacter inoculant concentration   on enhancement of hormones and total nitrogen content as well as  Azotobacter population in liquid culture. The experiment used Randomized Completely Design with six treatments and three replications. The treatments were combination of inoculant concentration (without, 5%, 10% and 15%) and  Fe-Mo solution (with and without Fe-Mo).  The result showed that addition of Fe and Mo microelements in liquid culture increased Cytokinin production as well as population density of Azotobacter.  Inoculant concentration of 10% with the addition of micronutrients  Fe  and  Mo  was  able  to  optimize  the  production  of hormones, nitrogen fixation, and cell density of Azotobacter. Keywords : Fe, Mo, Total Nitrogen, Hormone, Azotobacter

Abstract

The landscape changes through the increasing built-up areas (settlements and industrial) have a potential impact on reducing the quality of agricultural land. Waste from anthropogenic activities (industrial and domestic) is the main source of heavy metals that can affect rice production in the fields. This study examines the quality changes of paddy fields (Oryza sativa L.) polluted by wastewater in Muara Bakti Village, Bekasi Regency. Wastewater's impact on paddy fields is known through heavy metal contamination analysis in soil and rice plants. Chemical analysis of soil, water and plants was completed by the Balai Penelitian Tanaman Sayuran (Balitsa) Laboratory, West Bandung. The results showed that heavy metal levels such as lead (Pb) and cadmium (Cd) in the paddy soil samples were above the threshold in soil, respectively more than 25 mg/l and 0.01 mg/l. In contrast, the rice plant samples, it was identified as containing heavy metals such as Cd and chromium (Cr). Pb content was not detected in the rice plants. Soil in Muara Bakti Village contained optimal nutrients that are still suitable for agriculture. However, heavy metal content detected in soil samples and rice plants requires special handling to prevent endangering the agroecosystem and human health. Keywords: Agroecosystem, Heavy metals, Paddy fields, Soil pollution, Waste
