The study used a randomized block design with 2 treatment factors. Factor I is the inundation height (G) which consists of 0-10 cm inundated land (G1), 10-20 cm inundated land (G2). Factor 2 is the addition of ameliorant (A) consisting of: Humid Acid (A1), Zeolite (A2), and Gypsum (A3). Each treatment was repeated 4 times. Soil observation parameters were nutrient content consisting of acidity (pH), H2O, C organic, N total, P2O5 available, exchangeable cations (K, Na, Ca, Mg), and Electrical Conductivity (DHL) as well as heavy metal content consisting of: As, Hg, and Cd.

Many BUMDes’ (Township and Village Enter-prises/TVEs) manage agrotourism as their core businesses. Meanwhile, most of them have experienced a turnover-declining during the Covid-19 pandemic and need new managerial strategies to survive this pandemic. Human resource holds a strategic function in this problem since most of the BUMDes recruits their employers locally since it is designed to reduce unemployment in the village while utilizing the resources possessed by their villages. Contrarily, the pandemic of Covid-19 has given a severe impact on agrotourism in Indonesia and has pushed BUMDes’ to cut their employer numbers for reasons of efficiency. This study aimed to describe the human resources management conducted by BUMDes during the Covid-19 Pandemic, employing a qualitative approach with the chairman and employees of BUMDes as the informants. Data from this research were analyzed by Miles and Huberman’s model. The research was held on agrotourism-based BUMDes in Malang and Batu. The results indicated that the BUMDes’ managers used the strategy of the temporary off-work system when the government implemented community activity restrictions (PPKM). During this off-work time, BUMDes did not pay their employees but gave a food package as social assistance to the workers. It proved that BUMDes was applying a social systems approach in managing their employees during the pandemic to hold its function as one of the economic pillars for villagers.","PeriodicalId":19244,"journal":{"name":"Nusantara Science and Technology Proceedings","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135533493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of shoot trimming treatment and LOF NASA concentration of 2 ml/l water (P1K1) resulted in the best growth of pepper.

Field controlling with certain chemicals and biological agents have not been reported to be successful in reducing the Ganoderma incidence. This paper will be reporting about the potency of land management to minimize the incidence of basal stem rot disease in the next generation of oil palm plantations. Three methods of land management during the replanting process have been implemented, those are Windrowing the plant remnants (Windrow 1:1 & Windrow 2:1) as the main plot, Poisoning (No Poisoning and Poisoning) as a sub-plot and Fallowing (planting immediately and fallowing) as a sub-sub plot. The incidence of disease began to be observed two years after planting, by observing the canopy symptoms and the presence of Ganoderma’s fruiting bodies. Observations were made for 20 years, where at 5 years after planting, infections began to appear in the interaction treatment which belonged to windrow 1:1, non-poisoning and planting immediately. Meanwhile, at the end of the observation (20 years after planting), only the fallowing factor had a significant effect on the incidence of disease, where the percentage of disease incidence was half lower than without planting immediately (48.75%: 84.13%). This shows that the farther the plant is from the inoculum source (Windrow 2:1) will prevent the root contact of new plant to plant remnants and leaving the land not to be planted with oil palm for a certain period of time, reduced soil-borne disease agents, especially Ganoderma pathogens. Soil ploughing had been carried out exposing the soil to sunlight and exposing soil-borne disease organisms during the fallow process.","PeriodicalId":19244,"journal":{"name":"Nusantara Science and Technology Proceedings","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135533495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of biological control agents has several advantages. These advantages include limiting the growth and development of plant-disrupting organisms over a relatively long period. Furthermore, biological agents have advantages in maintaining the equilibrium of the ecosystem that is present in agricultural environments. Due to their ability to create antimicrobials and stimulate plant development, as well as the fact that they are plant growth-promoting rhizobacteria (PGPR) and can survive in adverse environmental circumstances, antagonistic bacteria are one of the biological or biocontrol agents for managing illness. Antagonizing microorganisms can boost plant resilience to disease attack without polluting the environment or leaving toxic residues in the food chain Bacteria with good antagonistic agent properties can prevent the growth of pathogens and stimulate plant resistance responses. In addition, antagonistic bacteria can simultaneously boost the growth response of plants (plant growth promoter). One of the antagonistic bacteria used as PPGF is Pseudomonas fluorescens. Pseudomonas fluorescens has been widely recognized as having the potential as a biological agent to inhibit several plant pathogens. P. fluorescensis a group of root bacteria that effectively suppresses various plant diseases, including damping off of seedlings, soft rot, bacterial wilt, and others on many plant varieties. An antibiotic substance produced by P. fluorescens.

One of the uses of endophytic bacteria in agriculture is as biological agent in overcoming the attack of the root-knot nematode Meloidogyne sp.

It’s control is important to reduce crop yield loss. Control of the nematode Meloidogyne sp., at this time use many chemical pesticides because they quickly kill nematodes, but the continuous use of chemical nematicides will potentially pollute the environment.  So, it is necessary to study alternative control using endophytic bacteria. The purpose of this study was to determine the potential of endophytic bacteria from wetlands of South Kalimantan as biological agents of it in celery plants. This research was conducted in Sumber Glagah, Pacet, Mojokerto, using Completely Randomized Design (CRD). The treatment was carried out by immersing the roots of celery plants in a suspension of endophytic bacteria (24 hours) and concentration (108 cfu/ml), then planted in polybags measuring 30 x 30. The polybags were filled with soil that had been divested with 50 juvenile Meloidogyne sp.
