Abstract

In 2020, lettuce production in Indonesia was only 101,129 tons, falling short of the market need of 300,204 tons. Fertilizer effects lettuce plant growth and production. The aim of this study was to establish the optimal dosage of cow manure and NPK fertilizer for lettuce plant development and productivity. The research was conducted on agricultural land in Rawa Selapan Village from April to June 2024. This study used a Randomized Block Design (RAK) with two components and three replications. The first factor, the dose of cow manure, had three levels: without cow manure (P0), 100 g/plant (P1), and 200 g/plant (P2). The second factor, the dose of NPK fertilizer, also had three levels: without NPK fertilizer (N0), 2 g/plant (N1), and 4 g/plant (N2). The collected data were examined using analysis of variance, and if there was a significant difference, a 5% BNT test was performed. According to the study's findings, fertilizing with cow manure at a dose of 200 g/plant resulted in better growth and results in the parameters of plant height, number of leaves, wet weight of plots, wet weight of samples, and dry weight of lettuce roots compared to treatments without manure and cow manure at a dose of 100 g per plant. The application of a dose of NPK fertilizer 4 g/plant resulted in good growth and results in the parameters of plant height, leaf width, wet weight per plot, and wet weight of lettuce roots when compared to treatments without NPK fertilizer and NPK fertilizer 2g/plant. No interaction was found between the combination of cow manure and NPK fertilizer dosages.

Abstract

Indonesia black rice is a potential crop which consider to be develop as functional food because of high nutritional values. However, some agronomical traits, such as high culm and long harvesting time need to be improved for high productivity. Genetic engineering based on protoplast system is one of tools that can be used for improving black rice agronomical traits. The purpose of this study was to establish an efficient method for obtaining protoplasts, and to get information on whether the PEG-mediated transformation method can be carried out on black rice ‘Cempo Ireng’ using GFP transient expression as a marker. To get protoplast culture, we used callus and seedling as main explants. The results showed that 15th days seedling was the best explant source to get protoplast compare to callus. The combination of 1,5% macerozyme and 3% celulase was optimum to obtain the viable protoplasts. Transient expression of GFP can be done using PEG-mediated protoplast transformation in 30% concentration of PEG.

Abstract

Kelompok Wanita Tani (KWT) Handayani Putri Kecamatan Gisting merupakan kelompok tani yang aktif dalam budidaya sayur khususnya cabai merah. Produksi cabai gisting tergolong dalam empat wilayah di Provinsi Lampung yang produksi cabainya rendah di Tahun 2022. Salah satu faktor yang mempengaruhi penurunan produksi adalah serangan organisme pengganggu tanaman. Hama utama yang menjadi permasalahan saat ini adalah kutu kebul, kutu daun dan kutu putih. Hal ini perlu adanya pendampingan pada proses budidaya cabai dalam pengendalian hama dan penyakit untuk mendukung optimasi produksi. Pengabdian ini melakukan sosialiasi pembuatan pestisida nabati dengan dua formulasi yang berbeda dan diujikan pada demplot cabai yang berbeda. Cabai yang digunakan dua jenis yaitu cabai hibrida (Sios Tavi F1) dan cabai lokal (Akar F1). Berdasarkan hasil pengabdian masyarakat yang telah berlangsung ketahanan penyakit keriting masih tergolong tinggi dan kuning tergolong rendah. Kejadian penyakit keriting cabai hibrida mencapai 52,13% dan cabai lokal mencapai 30% pada minggu ke-10. Kejadian penyakit kuning pada cabai hibrida 8,5% dan cabai lokal 8,7% dari total tanaman demplot. Kata kunci: penyakit keriting, penyakit kuning, Sios Tavi, Akar

Abstract

Plant growth promoting rhizobacter (PGPR) contains Rhizobacter which can fix free nitrogen found in nature, the nitrogen is converted into ammonia which is then distributed to plants. The aim of this research was to determine the effect of administering pgpr from two different bioactivator sources on the intensity of aphid attacks on chili plants. The experimental design used was a Completely Randomized Design (CRD) which consisted of two factors, namely the PGPR concentration of bamboo roots and mimosa roots, namely 0%, 25%, 50%, 75% and 100%. Each treatment was repeated 3 times with each experimental unit consisting of 4 curly chili plants of the Thunder 99 variety. Applications were carried out once a week during the vegetative period. Observations began at 1 WAP and once a week with the observation variables being the type of aphids and the intensity of aphid attacks on each plant during the vegetative period. The results obtained by administering PGPR bamboo roots and putrimalu roots were less effective because they were unable to suppress the intensity of aphid attacks on chili plants. Intensity of aphid attacks not different than control. The level of intensity of aphid attacks is directly proportional to the aphid population. PGPR that can relatively reduce the intensity of aphid attacks is bamboo root treatment with a concentration of 75%. A better PGPR bioactivator comes from bamboo roots rather than mimosa roots.

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

Abstract

The purpose of this study was to determine the best basic medium type and TDZ concentration for the development of somatic embryos from Dendrobium orchid leaf explants. Three replications were arranged factorial (2x3) in a completely randomized design for this study. First, there were two types of basic media, ½ MS and MS. The second factor was the concentration of cytokinin thidiazuron 1, 2 and 3 mg/L. Each experimental unit consisted of 5 culture bottles, each contained 5 explants. The research results showed that 1) The use of both types of basic media was able to induce callus formation on Dendrobium 'Gradita 31' orchid from leaf explants. 2) The use of 3 mg/L thidiazuron which combined with ½ MS or MS media was able to form primary callus faster than other treatments. 3) The higher percentage for embryo somatic and shoots formation were also found in 3 mg/L thidiazuron.
