Abstract

This PKM activity is aimed at Catholic Women in Airmadidi, North Minahasa Regency. In the initial survey, the target community expects knowledge and skills about making organic fertilizers. Because it coincided with the pandemic, the implementation of PKM activities was carried out through the zoom application with the delivery of material by resource persons about the benefits of using organic fertilizers and the potential of existing resources around/around the environment that can be used as a source of organic fertilizer. After that, through a video, they demonstrated how to make organic fertilizer by utilizing existing resources. This training on making organic fertilizers needs to be followed up with mentoring activities during manufacture to further refine and maximize the results of the activities. In addition to household waste, various other biological sources can also be tried as a source of organic fertilizer. The community needs to get higher motivation so that they want to continue to make and produce and utilize organic fertilizers by utilizing the biological resources that exist around them

Abstract

Caisim (Brassica chinensis var. Parachinensis) is a type of vegetable that is in great demand by the public, because it contains many nutrients that humans need. Using chicken manure on caisim plants to provide nutrients for plant survival and growth. This research aims to see and determine the growth response of caisim plants (Brassica chinensis var. Parachinensis) by administering varying doses of chicken manure. This research was carried out in Sea Village, Pineleng District, Minahasa North Sulawesi from January to February 2023.This research used a completely randomized design (CRD) method with varying doses of chicken manure, with chicken manure needs are : Without treatment (A0), 312,5 grams/ polybag (A1), 625 grams/ polybag (A2), 937,5 grams/ polybag (A3). Data analysis from the observations was analyzed using Analysis of Variance (ANOVA) and continued with the Least Significant Difference Test (LSD) with unequal replications.From the research result, the caisim plant lacks light in the plant growth process. The hypothesis was also rejected because varying doses of chicken manure had no effect on the growth and development of the caisim plant. It is recommended to choose an ideal research location for succes in the cultivation process, the importance of the need for sunlight in plant growth to influence photomorphogenesis, namely plant growth and development which is directly controlled by sunlight. Keywords : caisim, dosages of chicken manure

Abstract

Chrysanthemum (Chrysanthemum morifolium) is the most popular plant in Indonesia, because chrysanthemum flowers have their own advantages in terms of the beauty of their flower colors. The problem with chrysanthemum shoot cuttings is that the roots are not dense enough so that the chrysanthemum plant cannot grow upright. This research aims to determine the effect of Trichoderma sp. on vegetative growth of chrysanthemum plants. This research was carried out for 5 weeks, starting from July to August 2023 at the Green House of the Seed, Nursery and Agrotourism Center, Tomohon City. The method that will be used in this research is a Completely Randomized Design (CRD), with 5 treatments: P0 = No Trichoderma sp. (Control), P1 = Thricoderma sp. 25 gr/l, P2 = Thricoderma sp. 50 gr/l, P3 = Thricoderma sp. 75 gr/l, P4 = Thricoderma sp. 100 gr/l. All treatments were repeated 5 times so that there were 25 units. The data obtained based on observations in this research will be analyzed using Analysis of Variance (ANOVA). The variables observed were: number of leaves, plant height, number of roots, root length. The results of the study showed that the use of Trichoderma was not significantly different from the variables number of leaves, plant height and root length. Giving trichoderma only had a significant effect on the number of roots (giving 50g trichoderma/liter of water). Keywords: trichoderma sp., chrysanthemum cuttings, growth, results

Abstract

Spinach (Amaranthus sp) is a plant belonging to the Amaranthaceae family. Spinach is one of the oldest food plants in the world originating from America, which has been cultivated around 6700 years BC and is now spread throughout tropical and subtropical areas throughout the world. Copra fumigation ash contains macro and micro nutrients that plants need, one of which is potassium. This research aims to determine the effect of copra fumigation ash on the growth of spinach plants. This research was carried out at the Green House, Faculty of Agriculture, Sam Ratulangi University, Manado, North Sulawesi from June to July 2024. This research used a Randomized Group Design (RAK) with six treatments and four replications consisting of Without Ash Copra Fumigation (K0), 5 tons Copra Fumigation Ash/ha (K1), 10 tonnes of Copra Fumigation Ash/ha (K2), 15 tonnes of Copra Fumigation Ash/ha (K3), 20 tonnes of Copra Fumigation Ash/ha (K4) and 25 tonnes of Copra Fumigation Ash/ha ( K5). The research data were analyzed using the F test using the Microsoft Office Excel program to determine the effect of copra fumigation ash treatment on the growth of spinach plants. The research results showed that copra fumigation ash had a significant effect on the variable height of spinach plants but not on the number of leaves and width of spinach leaves. Copra fumigation ash also has a very significant effect on the fresh weight of spinach plants. It is recommended to use copra ash at a dose of 20 tons/ha as the recommended dose for spinach cultivation activities.

Abstract

Efforts to increase the productivity of land kale plants with environmentally friendly cultivation techniques are by utilizing kitchen waste to be processed into liquid organic fertilizer which can spur plant growth. This study aims to examine the effect of kitchen waste liquid organic fertilizer (POC) on the growth and production of land kale plants. This research was conducted in Tolok Village, Tompaso District, Minahasa Regency, North Sulawesi. This research began in October to December 2023. The field experiment was arranged in a Randomized Group Design (RAK), with one treatment factor, namely the concentration of kitchen waste POC, consisting of P0 = 0 ml/l (control), P1 = 25 ml/l, P2 = 50 ml/l, P3 = 75 ml/l, and P4 = 100 ml/l. Parameters observed were plant height, leaf length, number of leaves, and plant fresh weight. Data were analyzed using Analysis of Variance (ANOVA) at the 5% test level if testing with the F test is significant, followed by a different test of the means using the BNT (Least Real Difference) test at the 5% level. The results showed that the provision of POC had an effect on plant height, leaf length, number of leaves, and fresh weight of plants. Giving the best kitchen waste POC is at a concentration of 100 ml/liter, which gives the highest results in all parameters observed. Keywords: liquid organic fertilizer, kitchen waste, land kale
