Abstract

Pakchoy is a leafy vegetable that is great demand by Indonesians. The increase in population has had a major impact on agricultural land, which has encouraged an urban farming system, using polybags for crop production. The use of soil media in polybags often experiences compaction and lack of nutrients, so it is necessary to modify the composition of the planting media and put additional fertilization. This research was conducted to evaluate the response of pakchoy to local microorganisms based on rice waste and to determine the best composition of growing medium for pakchoy plants. This study used a completely randomized design (CRD) with 2 factors. The first factor was the local microorganism (LMO) doses of rice waste consisted of 4 levels, namely 0 ml, 500 ml, 1000 ml, and 1500 ml per plant. The second factor was the composition of the planting medium (Soil : Sand: Cow Manure) at 4 levels, namely Soil 100%, 1:1:1, 1:1:2, 1:1:3. Data were statistically analyzed with ANOVA at 5% level. Mean separation was tested further with Duncan Multiple Range Test. The results showed that the LMO 0 ml and 500 ml performed higher effects on plant height, number of leaves, plant fresh and dry weight, root fresh and dry weight, and root length compared to the application LMO at 1000 ml and 1500 ml. The highest plant fresh weight was 193.1 g at 0 ml LMO, followed by 160.35 g at 500 ml LMO.   The composition of the planting medium 1:1:1 and 1:1:2 resulted in a higher number of leaves, plant dry weight, and root weight than other treatments. Incorporating a high portion of manure into the pakchoy planting medium was not beneficial. All growth variables and yield were higher compared to the control medium (soil 100%).  Key Words: pakchoy, local microorganism,  planting media

Abstract

Bioherbicides that utilize the allelopathic properties of sorghum plants that experience drought stress are fundamental to sustainable agriculture. This study aimed to look at the efficacy characteristics and flavonoid levels of Suri 4 extracts that have experienced various levels of drought stress. Extract materials were prepared from May to July 2024 at Bengkulu University Greenhouse, Kandang Limun, Bengkulu City, and bioassay tests were conducted in August 2024. Flavonoid analysis was performed at the Integrated Research and Testing Laboratory (LPPT) of Gadjah Mada University in August 2024. This research used a completely randomized design with one factor. One sorghum variety, Suri 4, was planted with water stress treatment through watering patterns every day, every 2 days, every 3 days, every 4 days, and every 5. The bioassay experimental unit was a petri dish, and the experiment was repeated four times. Each petri dish was given 10 mL of water extract, and 25 mung bean seeds were planted and incubated for three days. The results showed that the highest flavonoid levels were achieved by the 5-day watering pattern (3841.65 µg/g), and the lowest flavonoid levels were completed by the daily watering pattern (2948.07 µg/g). The highest germination inhibition was due to the sorghum water extract from the 4-day and 5-day watering patterns and was the best bioherbicide pioneer

Abstract

Contamination of  heavy metals on the soil leads to an increase in its acidity. Vermicompost application is commonly used to improve the properties of soil. The study was carried out to determine the reduction of the acidity in Pb and Cd contaminated soils under the application of vermicompost. Two laboratory experiments were set using Completely Randomized Design (CRD) with two factors. The first factor was soil samples, vis Inceptisols, and Entisols, and the second factor was the rates of vermicompost, consisted of 0, 5, 10, 15 g kg-1. The treatment combination was repeated three times. The soils were pretreated with 10 mg kg-1 Pb or Cd using Pb(NO3)2 and Cd(NO3)2. Three hundred kg soil sample was incorporated with vermicompost and placed in a 500 ml plastic bottle. The mixtures were incubated for eight weeks, and the moisture of the soil was maintained at field capacity. The acidity and soil temperature were monitored every week. The study indicated that Pb contaminated soil acidity increased to the sixth week of the incubation and decreased afterward. However, the acidity of Cd contaminated soil was consistently increased during the incubation. Treatment of vermicompost significantly lowered the acidity of both Pb and Cd contaminated soils. Contaminated Entisols had a higher response to the application of vermicompost than that of Inceptisols. This finding is significant in assessing acidity risk and possible management intervention for Pb and Cd contaminated soils.

Abstract

Soil properties play essential roles in transmitting and holding precipitation water; therefore, they determine the amount of plant-available water in the soil profile. The study aimed to compare the size distributions of Andept soil pores following four-year applications of vermicompost and liquid organic fertilizer (LOF). The experiment was done from 2016 to 2019. The five doses of vermicompost (5, 10, 15, 20, and 25 Mg ha-1) set as the main factor, supplemented with 0 and 100 percent concentrations of LOF as a sub-factor, were arranged in a split-plot design with three replicates. Results showed that adding LOF decreased slow-drainage pores significantly when combined with 10 Mg ha-1 of vermicompost. However, the pore changes by LOF were not significant when applied to other doses of vermicompost. Applying vermicompost and LOF lowered the slow-drainage pores by increasing soil organic carbon and reducing soil particle density. The findings suggest that vermicompost and LOF act as soil ameliorants to reduce water loss by drainage from soil profiles. The study highlights the importance of soil properties in determining plant-available water in the soil profile.

Abstract

The potential of sorghum plants to produce allelopathy is determined by the variety and the level of stress it receives. This study aimed to obtain information on the potential of sorghum water extract as a bioherbicide due to water stress treatment with different varieties. This study used a one-factor group randomized design. The extract source treatments were as follows: Super 2 + watering once every 1, 2, and 3 days; Suri 4 + watering once every 1, 2, and 3 days; Bioguma + watering once every 1, 2, and 3 days and control. Bioassay method experiments in petri dishes. Each petri dish was given 10 ml of aqueous extract with a concentration of 5%. A total of 25 sorghum seeds were planted and incubated for three days. The results showed that all water extracts from sorghum varieties Super 2, Suri 4, and Bioguma, combined with all water stresses, could inhibit the growth of the test plants. However, Super 2 + once every 5 days inhibited the test plants the most compared to the other treatments. Therefore, these sorghum water extracts have the potential to be used as bioherbicides to control weeds

Abstract

Kegiatan budidaya tanaman yang dilakukan oleh petani di Kecamatan Muara Bangkahulu menghasilkan limbah pertanian yang tidak sedikit. Tanpa adanya pengelolaan maka limbah pertanian tersebut dapat mencemari lingkungan. Pengolahan limbah pertanian menjadi kompos organik merupakan salah satu alternatif untuk mengubah barang yang kurang bernilai menjadi barang bermanfaat dengan nilai jual yang tinggi. Sasaran dalam kegiatan pengabdian ini adalah anggota kelompok wanita tani (KWT) Perintis 2 Pematang Gubernur Kota Bengkulu. Metode yang diterapkan yaitu : (1) Sosialisasi dan penyuluhan tentang limbah pertanian dan cara pengelolaannya, (2) praktek pembuatan pupuk organik dari limbah budidaya tanaman. Kegiatan ini dilaksanakan lima kali di Rumah Ketua Kelompok Wanita Tani. Hasil kegiatan ini menunjukkan antuasisme warga yang sangat tinggi dalam meningkatkan wawasan dan pengetahuan tentang pengelolaan limbah pertanian khususnya limbah budidaya tanaman. Sebagian besar anggota kelompok tani kurang mengetahui bahwa limbah sisa pertanian dapat dijadikan pupuk organik yang bermanfaat bagi tanaman dan mempunyai nilai jual. Diharapkan edukasi pembuatan kompos dari limbah hasil panen kacang tanah dapat diterapkan untuk mengatasi limbah pertanian yang menumpuk di lahan pertanian.
