Abstract

Dry land has several limiting factors, namely low organic C, low soil fertility, and limited water caused by very low rainfall. Strategies to increase the productivity of dry land can be done by combining the use of organic matter, cover crops, and intercropping crop systems. The existence of functional microbiota including phosphate solubilizing bacteria (PSB) and arbuscular mycorrhiza (AM) could be used as an indicator to evaluate the status of soil health in agricultural dry land areas. The purpose of this study was to analyze and compare the population density and diversity of PSB and AM in the rhizosphere of maize and peanut in monoculture and intercropping dry lands. A descriptive exploration method was conducted by sampling the rhizosphere soil of maize and peanut in the monoculture and intercropping dry lands to analyze the population density and diversity of PSB and AM spores. Each plot was analyzed in 3 replications. The results showed that the rhizosphere soil of maize in the monoculture dry land had the highest population density and diversity of PSB followed by maize in the intercropping dry land. The rhizosphere soil of maize in the intercropping dry land showed the highest AM spore density and diversity followed by maize in the monoculture dry land. So, this finding indicated that maize plants provide more conducive services in dry land.

Abstract

Curly chili (Capsicum annum L.) is a horticultural plant that is included in the vegetable commodity. Production of curly chilies in Indonesia is still unstable so the need for curly chilies is not met so production needs to be increased. This research aimed to determine the effect of the optimal dose of guano fertilizer and concentration of the Atonik Growth Regulator on the yield of curly chili plants The research location is on cultivated land of the Faculty of Agriculture, Universitas Pembangunan Nasional “Veteran” Jawa Timur. This research used a factorial experiment which was prepared using a Completely Randomized Design consisting of 2 factors. The first factor is the dose of guano fertilizer (G) consisting of G0: control, G1: 30 g / polybag, G2 : 60 g / polybag, and G3 : 90 g / polybag. The second factor is the atonic ZPT concentration consisting of A0: control, A1: 2 cc/liter, and A2: 4 cc/liter. Observation indicators consist of observations of the vegetative and generative phases. Research data will be analyzed using variance (ANOVA) and if it is significantly different it will be tested further using the Least Significant Difference (BNT) at the 5% level. The results of the research showed that the application of guano and atonic fertilizers affected the yield of curly chili plants with the most effective combination being a dose of guano fertilizer of 90 g/polybag and an atonic concentration of 4 cc/liter.

Abstract

Water spinach (Ipomea Aquatica) is one of the superior commodities that is often used in urban farming cultivation models. The short lifespan and easy maintenance are the reasons water spinach is chosen for urban farming cultivation. One of the factors that must be considered when cultivating water spinach using urban farming is sufficient sunlight intensity for optimal growth of water spinach. This research aims to analyze the growth and yield of water spinach in the urban farming cultivation model using location placement treatments that have different sunlight intensities. The research method used for analysis of growth and yield which are presented in graphs and analyzed using t-tests. The results of plant growth urban farming water spinach for the parameters of plant height and number of leaves with different treatments of sunlight intensity showed that the values were not significantly different. However, water spinach plants in the unshaded treatment had a higher average plant height and number of leaves than those in the shaded treatment. Meanwhile, the fresh weight and dry weight of water spinach showed that plants with unshaded performance had a higher weight than shaded plants.

Abstract

Increasing the yield and quality of cayenne pepper can be obtained by expanding the size of the cayenne pepper fruit, while the size of the cayenne pepper fruit can be expanded through polyploidy mutation. The research aims to increase the size of the small fruit and plants of cayenne pepper. A single factor experiment was designed in a randomized block design which was repeated five times. The soaking colchicine solution treatment for cayenne pepper seeds consists of 0 ppm; 1 ppm; 5 ppm; and 1 ppm plus dripping colchicine on the shoot buds after the second leaf appeared; 5 ppm colchicine with dripping colchicine on the shoot buds after the second leaf appeared. The data recorded included morphological characters at the seedling and plant phases and then analyzed variance and honest significant difference tests using the Excel-Program. Results showed that the application of colchicine 1 and 5 ppm plus dripping colchicine on the shoot buds after the second leaf appeared were significantly different with no dripping colchicine on shoot buds in seedling height, seedling leaves number, and seedling leaves area. At the plant phase, the highest leaves area was obtained by application of colchicine 1 and 5 ppm without dripping at shoot buds and control (0 ppm) treatments, however highest diameter of fruits achieved by colchicine 1 and 5 ppm with dripping it at shoot buds and highest fruit number observed at no colchicine (control) treatment.

Abstract

The need for food such as vegetables is increasing along with the growing population. However, the high demand for lettuce is not matched by the expansion of the area of ??agricultural land, which is actually getting narrower. Utilization of narrow land in lettuce cultivation can use a hydroponic system which has become an increasingly popular choice for farmers and consumers. The research was conducted on January 2, 2023, at the Ketindan Agricultural Training Center (BBPP). Observations were made when the lettuce was 7, 14, 21 and 35 DAP (Day After Planting) with measurement parameters namely number of leaves, plant height, and farming analysis. The results of observations made on hydroponically cultivated lettuce at the age of 35 DAP had an average number of leaves of 15.74 with the highest number of leaves being 19 and the least being 14. Lettuce plants have an average height of 18.81 cm, with the highest plant being 22.5 cm and the lowest being 17 cm. the profit earned is Rp. 284,070 in each harvest. The value of hydroponic lettuce farming is profitable because the R/C ratio reaches 2.32. The growth in height of lettuce plants is directly proportional to the increase in the number of leaves of lettuce plants and the cultivation of lettuce plants that have been carried out can be categorized as profitable because the value of the R/C ratio is more than 1.

Abstract

Corruption obliteration presently focuses on three main issues: prevention, obliteration, and asset recovery. Eradicate corruption not only focuses on preventing and eradicating but also improves the terms of punishing the perpetrators and is also associated with seeking to recover state financial losses from the proceeds of corruption crimes. The provisions in question are of great hope for systematic and comprehensive anti-corruption measures, which feature not only criminal prosecution of corruption crimes but also the protection of national finance, that is, the obligation to return state funds from the perpetrators of criminals. Corruption crimes can be used for national development. Therefore, normatively it would not be excessive if the provisions of Article 18 of Constitution no. 31 of 1999 in conjunction with Constitution no. 20 of 2001 regarding the Obliteration of deceits of corruption can be an effective legal instrument for compensating the State for losses caused by corruption crimes.

Abstract

Ralstonia solanacearum is a pathogen that causes bacterial wilt in tomato plants (Lycopersicum esculentum), can decrease production until 90%. The controls generally use chemical pesticides which are harmful to the environment and humans, so it is necessary alternative controls using endophytic Fusarium sp. The aim of the research was to determine the effect of endophytic Fusarium sp. to bacterial wilt. Endophytic Fusarium sp. was explored on tomato plant in Tlekung, Junrejo-Batu and taken systematically randomly then brought to the laboratory. Isolation of endophytic fungi was done by washing the plants with running water, cutting 1cm then was sterilized. The sample was planted on Potato Dextrose Agar (PDA) and incubated at 37°C for 48 hours, if its growth was purified on new media. Isolation of R. solanacearum was done by washing the stems, cutting 0.5 cm then sterilizing. The piece is put into a test tube, added 10 ml of sterile water until the bacterial mass comes out and dissolves in sterile water. The mass of bacteria in sterile water is shaken using vortex until suspension forms. The suspension was grown on TZC agar and incubated at 280C for 24 hours, if it grow was purified on new media. Application of endophytic Fusarium sp. carried out using immersing technique of the roots of tomato plant. Inoculation of R. solanacearum was done into sterile soil before the plant were planted. The study used completely randomized design (CRD) with control and isolate of endophytic Fusarium sp. as treatments with 3 repeat and conducted in the greenhouse of the Faculty of Agriculture UPN "Veteran" East Java. Observations are incubation period and disease intensity, data were analyzed using BNT 5%. The results show that endophytic Fusarium sp. delayed the period incubation and suppressed the intensity of bacterial wilt disease in tomato plants.

Abstract

A Hemp plants are plants that have not been much research and exploration. Propagation of flax plants can be carried out by propagation of rhizomes. Other propagation can use cuttings of rootstocks, middle stems, and shoots, although such propagation is not yet optimal and has a presentation of about 60% on its failure. Genetic diversity in hemp plants aims to increase germplasm. Genetic diversity in multiplying germplasm means to increase the collection of hemp plants. Environmental changes in plant populations can be overcome by genetic diversity. This study aims to identify the germination and success of EMS chemical mutations in the results of hemp plant seed mutations (Boehmeria nivea L.). Observations were made on several hemp seed accessions, namely Kumamoto (KM), Bandung A (BDA), Lembang A (LA), Indochina (IDC) and Seiki Selskin (SS). Observational measurements were carried out when the seeds were 7, 14, and 21 DATT with parameters of percentage of germinated seeds and percentage of mutation results. From the observations, the highest percentage was obtained in 2 accessions, namely Bandung A (BDA) and Lembang A (LA) with a percentage of 41.3%. The lowest percentage was found in Indochina's accession with a presentation of 29.3%. The percentage of inhibited germination was highest in EMS treatment of 0.25% with a soaking period of 6 hours. When compared again with treatment control which is almost close to the percentage of germination is at a soaking duration of 3 hours.

Abstract

Anthracnose is an important disease in chili plants because yield losses can reach 80%. This disease is caused by the fungus Colletotricum spp. The control that is often used is with chemical pesticides which cause negative effects on the environment. The refore it is necessary to use alternative control using biological agents that are environmentally friendly and support sustainable agriculture. This activity aims to determine directly the causes of anthracnose disease and the inhibition percentage of Tricoderma sp and Pseoudomonas fluorencens against anthracnose fungi in vitro on chili plants at the Ketindan Agricultural Training Center (BBPP). The test used the pour plate method (combining media with biological agents) with 3 treatments, 3 replications and 1 control. The test results showed that Trichoderma sp had an inhibition percentage of 100% while Pseudomonas fluorencens had an inhibition percentage of 28.06% and 100%. Trichoderma sp can inhibit the growth of anthracnose fungi because it has a competition mechanism for nutrients and space, hyper-parasitism, and produces antibiotic compounds while Pseoudomonas fluorencens has a mechanism for producing antibiotic compounds. Based on the observations, it can be concluded that Trichoderma sp and Pseoudomonas fluorencens were able to inhibit the growth of the fungus Colletotricum gloeospoioides in vitro.
