Saline land in coastal areas has the potential for expansion of agricultural areas for food crops, especially rice when considering the availability of water and choosing the right planting time. Field experiments were carried out to know the characterization of saline land suitable for rice cultivation. The study was located in Purwokero Village, Brangsong District, Kendal Regency in 2018 ing soil samples before treatment and after ameliorant treatment, namely 25 days and 48 days from the research location. 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. Observational data were analyzed descriptively comparatively. The results showed that the special rice fields for the study included saline land due to seawater intrusion, which were characterized by DHL>4 ds, pH

Agrotourism has an important role in developing the economy and has been a source of job opportunities in the villages in Indonesia. 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.

This study aims to determine the best of combination treatment of pruning type and concentration of liquid organic fertilizer (LOF) on the growth and yield of pepper plants whose production is still low and has not yet achieved its production potential which can reach 20 tons/ha. The factorial study with 2 factors was arranged in a completely randomized design (CRD) which was repeated 3 times. The first factor is the type of pruning (P) which consists of 3 levels, namely: P0 = Not pruned (control), P1 = Pruning shoot tip, P2 = Pruning axillary shoot, while the second factor is the concentration of LOF NASA which consists of 3 levels , namely: K0 = 0 ml/l (control), K1 = 2 ml/l, and K2 = 4 ml/l. The results showed that there was a significant interaction between the combination of shoot pruning treatment and LOF NASA concentration on the number of branches and the number of productive branches. The combination of shoot trimming treatment and LOF NASA concentration of 2 ml/l water (P1K1) resulted in the best growth of pepper. Meanwhile, the single factor type of shoot tip pruning (P1) and LOF NASA concentration of 2 ml/l (K1) produced the best number of fruits and fruit weight of papper compared to other treatments.

Ganoderma causes basal stem rot disease is a serious threat to the palm oil industry, especially in Malaysia and Indonesia. 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.

Biological control is a long-term and environmentally friendly method of pest management. 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. (2,4-diacetylphloroglucinol/ 2,4-DAPG) can increase soil resistance to pathogens.

Purslane is an annual plant that has various benefits. This plant contains omega 3 which is equivalent to other types of vegetables. So far, purslane is still considered a weed, so it doesnt have a cultivation technique to get the results. This study aims to obtain a combination of planting media for the growth of purslane. This research is the beginning to increase the purslane omega 3 content. Because genetic factors and environmental conditions can affect the growth and development as well as the chemical content of plants. The experimental design used a completely randomized design (CRD). The planting media used were: soil, soil + husk charcoal, soil + compost, and soil + husk charcoal + compost. The treatment was repeated 4 times, so there are 12 observation units. Observations were made on the number of leaves and the number of branches. The results showed that the combination of soil+compost gave the best effect on the number of leaves and the number of branches of the purslane seedling

Endophytic bacteria are microorganisms that are associated with plants, don’t cause disease, and mutualism associated with plants. 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 is a polyphagous parasite that can attack plants by forming galls on the roots of celery plants (A. graveolens), can lack nutrients, and in chronic conditions causes death of host plants. 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. Observation parameters were the number of galls per g of roots and juvenile population per g of root and per 10 g of soil. The results showed that the treatment of endophytic bacteria reduce: (1) number gall per g celery roots was 19.67–31.00 and control (46.67); (2) population juvenile population per g root was 9.33-25.67 and control 50.67; (3) juvenile population per 10 g of soil was 11.33-17.00 and control 29.33.

The results showed that the treatment of endophytic bacteria reduce: (1) number gall per g celery roots was 19.67–31.00 and control (46.67); (2) population juvenile population per g root was 9.33-25.67 and control 50.67; (3) juvenile population per 10 g of soil was 11.33-17.00 and control 29.33.","PeriodicalId":19244,"journal":{"name":"Nusantara Science and Technology Proceedings","volume":"77 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":"135533297","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}
Rice Ragged Stunt Virus (RRSV) is one of the plant diseases or annoyances in rice plants where the Brown Planthopper (Nilaparvata lugens Stal) is the vector. In the first dry season (MK 1) in 2022, the area of rice plants in Madiun experienced symptoms of RRSV almost reaching 10%. Most farmers grow the Inpari 32 rice variety which has various advantages, including grain weight, high yield percentage and the brightly colored character of the grain. But in first dry season (MK 1) of 2022, Inpari 32 is a rice variety that is heavily attacked by RRSV. This study was carried out on 4 varieties, each Inpari 32, Inpari 42, Inpari 16, and Ciherang, with the aim of knowing whether there were noticeable differences in the intensity of RRSV attacks and yield losses in the four varieties. Data collection was carried out in 19 villages in Madiun. The results of the 5% Tukey HSD Test found a noticeable difference, Inpari 42 is the variety that shows the least yield loss among 3 other varieties, each Inpari 32, Inpari 16, and Ciherang.
