Abstract

This study aims to evaluate the growth and vitamin C content of red amaranth microgreens (Amaranthus tricolor) under various nutrient concentrations and growing media. The experimental design used in this study was a Randomized Complete Block Design arranged factorially 5 x 3 (15 treatments) with 3 repetitions. The first factor was the concentration of hydroponic nutrients at levels of 0 ppm, 100 ppm, 200 ppm, 300 ppm, and 400 ppm. The second factor was the combination of growing media, namely sand + sawdust, sand + rice husk charcoal, and sand + cocopeat, with a 1:1 ratio for each combination. Data obtained from the observed variables were analyzed using variance analysis and further tested with an LSD test at a 5% significance level. The observed parameters included germination rate (%), plant height (cm), number of leaves, leaf color, root length (cm), number of roots, plant weight (mg), and vitamin C content. The results showed that the use of sand + rice husk charcoal as a growing medium was very suitable for the germination of red spinach microgreens. However, for leaf color and root length, the use of sand + cocopeat was better. The sand + cocopeat medium combined with nutrient concentrations of 300 ppm and 400 ppm produced the best plant height and sample weight compared to other treatments. Furthermore, the sand + sawdust medium was very effective in producing the number of roots and the vitamin C content of red spinach microgreens.

Abstract

The use of shade percentage is the main factor as a barrier to sunlight which functions to reduce the intensity of the sun and as a weed control. Liquid biological organic fertilizer is fertilizer that contains microbes and is useful for helping plant growth. The aim of this research is to determine the best shade presentation and concentration of liquid biological organic fertilizer and their combination on the growth and yield of celery plants. This research was carried out from August to November 2023 at the Lampung State Polytechnic Land. This research was a split plot experiment (3 x 3) which was repeated 3 times. The first factor used as the main plot is the percentage of shade which consists of three levels: no shade, 30% shade, 60%. The second factor used as a subplot is the concentration of liquid biological organic fertilizer which consists of three levels: control, 10 ml.l-1, 20ml.l-1. If the results show a significant effect, it will be continued with the Honestly Significant Difference (BNJ) test at the 5% level. Based on the observations result, it can be concluded that there is no good combination between the shade percentage treatment and the concentration of liquid biological organic fertilizer on the growth and yield of celery plants. The shade percentage treatment of 30% gave the best results for all observation parameters tested. Treatment of liquid biological organic fertilizer with a concentration of 10 ml.l-1 gave the best results in all observed parameters except for plant height parameters.

Abstract

Oyster mushroom is a commodity that is in high demand in the community. Oyster mushroom production in Indonesia is decreasing year after year as wood sawdust, which is often used as a media for oyster mushrooms, becomes increasingly difficult to get. Bamboo has a nutrient content similar to wood sawdust; therefore, bamboo sawdust can be utilized as a media for growing oyster mushrooms. The aim of this research was to find the best mixture of bamboo and wood sawdust for the growth and yield of oyster mushrooms (Pleurotus ostreatus). This research was carried out from July to October 2023 at Lampung State Polytechnic. This study used a randomized block design with one factor that was repeated four times. The following treatments were used: C0 = 100% wood sawdust, C1 = 90% bamboo sawdust + 10% wood sawdust, L2 = 80% bamboo sawdust + 20% wood sawdust, C3 = 70% bamboo sawdust + 30% wood sawdust, C4 = 60% bamboo sawdust + 40% wood sawdust, and C5 = 50% bamboo sawdust + 50% wood sawdust. The collected data was analyzed using analysis of variance (ANOVA) and then evaluated with LSD test at the 5% level. The results of this research were that the treatment of C5 = 50% bamboo sawdust + 50% wood sawdust gave the best results on the parameter of the mycelium growth rate, the time of the fruit body initiation (FBI), the number of hoods, the diameter of the hood, the thickness of the hood, the harvest, the harvest weight per baglog, and the total harvesting per plot.

Abstract

The problem faced by hydroponic farmers in cultivating chili peppers is the lack of an optimal AB Mix nutrient formula that can be synthesized independently using chemical fertilizers readily available in agricultural supply store. This study aims to evaluate the effects of AB Mix nutrient formulation and variety on yield of curly chili peppers (Capsicum annuum L.) in hydroponic system. The experimental design was a Randomized Block Design (RBD) in 2-factor split-plot arrangement with three replications. The main plots consisted of four nutrient formulations. The subplots consisted of plant varieties, which included the Lado Juara F1 variety, the Joker genotype, and Lolay genotype. The result of the study showed that increasin of the concentration of the AB Mix nutrient formulation from N1 to N2 enhanced the number of fruits and the fruit weight per plant, both in the Lado Juara, Joker, and Lolay varieties. However, further increases the concentration of the AB Mix nutrienr formulation from N2 to N3 and N4 decreased the number of fruits and the fruit weight per plant in any of varieties. The use of the Lado Juara variety resulted in higher numbers of fruits and fruit weight per plant compared to the Joker and Lolay genotypes across all AB Mix nutrient formulations with a drip irrigation hydroponic system.

Abstract

Cauli flower is a vegetable from the Brassicaceae family which has high economic value. However, flowering cabbage easily experiences a decline in economic value due to the production of flowering cabbage being attacked by Plutella xylostella. P.xylostella attacks can reach 50-100%, so integrated control is needed to be able to control it effectively and efficiently. Technical and biological cultural controls are the controls applied in this research. The aim of this research was to assess the resistance of flowering cabbage to P.xylostella attacks by applying hedge crops and NPK doses to flowering cabbage. The research was structured using a complete randomized block design with two factors. The first factor is the type of hedge plant, namely spring onions, rampai tomatoes and tagetes, while the second factor is the NPK dosage, namely 100, 200, 300, 400 and 500 kg/ha. The results showed that there was no real interaction between the variables of plant height, flower appearance time, flower weight and P.xylostella attack. However, the border tagetes type was able to suppress P.xylostella attacks. P. xylostella attacks reached 33%.

Abstract

Tomato plants are expected to have an ideal growing environment to optimize their growth and production. Therefore, this study aimed to investigate the effect of various concentrations of biofertilizer, mulch types, and their interactions on growth and production of the Gustavi F1 tomato cultivar. A randomized group design (RGD) arranged factorially was used for the analysis, with the first factor consisting of no mulch (M0), straw mulch (M1), and plastic mulch (M2). The second factor was five biofertilizer concentrations, including 0 ml.l-1 (L0), 5 ml.l-1 (L1), 10 ml.l-1 (L2) 15 ml.l-1 (L3), and 20 ml.l-1 (L4). Data were analyzed using the F test (analysis of variance), and in cases of significant differences, the analysis proceeded with Duncan Multiple Range Test (DMRT) at an α level of 5%. Growth parameters observed in the experiments included plant height at 1 and 3 weeks after planting, while production parameters comprised fruit diameter, the number of fruits per plant, the percentage of fruits experiencing Blossom End-Rot (BER), and fruit weight per plot. The results showed that the use of plastic mulch significantly increased the number of fruits per plant, while the 0 ml.l-1 biofertilizer concentration showed the most effective reduction in the percentage of fruits experiencing BER. Moreover, an interaction between mulch and biofertilizer treatments was observed, particularly in relation to plant height 1 week after planting, the number of fruits per plant, and the percentage of fruits experiencing BER.Keywords— generative, microbes, ground cover, vegetative

Abstract

Abstract: This community service aims to guide chili farmer groups, especially the Handayani farmer group, to start cultivating chili plants organically on their farming land.There were three stages of the implementation method used, namely increasing knowledge, increasing skills and evaluation. Increasing knowledge was given through lectures to provide knowledge about the cultivation of organic chili plants, botanical pesticides and production of compost made from Azolla pinnata; followed by skills improvement by making botanical pesticides, propagating Azolla pinnata and making compost, demonstration plots of chili plants and then evaluation. Guidance for demonstrations on how to cultivate organic chilies started with planting seeds on the ridge, applying azolla compost to the planting holes, then planting chilies and applying botanical pesticides. Farmers planted chilies in beds that had been made as many as 192 plants which were divided into 6 beds. Afterwards, there were carried out the maintenance activities, controlling pests and diseases with the application of botanical pesticides, and harvesting along with post-harvest handling. This activity would be monitored. Monitoring was carried out once a month, especially at the end of each group of practiced cultivation activities. As an indicator of success, the results of the activity evaluation showed an increase in knowledge of organic farming concepts of 55% and an increase in skills of 85%.   Keywords: Sidokaton village, Pesticide Organic, Azolla pinnata
