The Effect of Giving of Local Microorganisms (MOL) on Bamboo Shoots on the Growth of  Eye Stum Rubber Seedlings (Hevea brasiliensis Muell. Arg.) IRR 112 clone in Polybags. This study aimed to determine the effect of giving Local Microorganisms (MOL) bamboo shoots to the growth of rubber stumps (Hevea brasiliensis Muell. Arg.) IRR 112 clones in polybags. The treatments studied were Local Microorganisms (MOL) with a concentration (P0) without MOL concentration, (P1) 10 ml MOL/liter water, (P2) 20 ml MOL/liter water, (P3) 30 ml MOL/liter water, (P4 ) 40 ml MOL/liter of water, (P5) 50 ml MOL/liter of water. The variables observed were shoot emergence (hst), shoot height (cm), shoot diameter (cm), number of leaves (strands), root wet weight (g), root dry weight (g), plant wet weight (g), and plant dry weight (g). Based on the results of the study, it was concluded that, giving MOL bamboo shoots at a dose of 20 ml/l water (P2) had a good effect on shoot height, namely 30.25 cm at 8 mst and 34.03 cm at 10 mst, shoot diameter was 6.12 cm at 8 mst and 6.23 mst at 10 mst, number of leaves 29.19 strands, plant wet weight 21.43 g, plant dry weight 6.92 g, root wet weight 41.75 g and root dry weight 17.70.

This research aims to see the effect of administering various doses of local bamboo shoot local micro organisms on the growth and yield of pakcoy mustard greens using a floating raft hydroponic system. The research was carried out at the Green House, Faculty of Agriculture, Tridinanti University, Palembang City, South Sumatra Province. The research was carried out from February to March 2024 (22 February 2024 when the seeds were transferred to the installation and 21 March 2024 when the plants were harvested). The research was carried out using an experimental method using a Randomized Block Design consisting of 6 (six) treatments and 6 (six) replications. The treatments studied were: P₀ = 10 ml AB ​​Mix/l water (positive control), P₁ = 50 ml MOL/l water, P₂ = 100 ml MOL/l water, P₃ = 150 ml MOL/l water, P₄ = 200 ml MOL/l water and P₅ = 250 ml MOL/l water. The variables observed were: plant height (cm), number of leaves (strands), leaf area (cm²), wet stem weight (g), upper wet stem weight (g), lower wet stem weight (g) and dry stem weight (g). The results of the research showed that the use of various doses of local micro organisms from bamboo shoots in the floating raft hydroponic system had a very good effect on the growth and yield of pakcoy mustard greens. The 10 ml AB ​​Mix/l water treatment turned out to produce better growth and yield of pakcoy mustard greens compared to all local micro organisms treatments for bamboo shoots. The growth and yield of pakcoy mustard greens using the floating raft hydroponic system when compared between the local micro organisms bamboo shoot treatment alone, the 150 ml MOL/l water treatment produced good growth and yields of pakcoy mustard greens, namely an average plant height of 16,08 cm; average number of plant leaves 16,00 (strands); average plant leaf area 366,18 cm²; average plant wet fruit weight 51,98 g; the average wet weight of the upper plant is 35,44 g; the average wet stem weight of the lower plants was 16,54 g and the average dry stem weight of the plants was 4,48 g.

This research aims to examine the effect of various types of foliar fertilizer on the growth and yield of baby corn (Zea mays L. var. saccharata Sturt). This research was carried out in the Experimental Garden of the Faculty of Agriculture, Tridinanti University, located in Semambu Village, North Indralaya District, Ogan Ilir Regency, South Sumatera Province. The research was carried out from January 2024 to March 2024. The research design used was an experimental method using a Randomized Block Design (RAK) with 5 (five) treatments and 5 (five) replications. The number of plants studied in the experimental unit was 5 (five) samples. The treatments studied were = No foliar fertilizer (control), = NASA Liquid Organic Fertilizer,  = Green Tonic Fertilizer, = S.Floran Fertilizer and = Bayfolan Fertilizer. The parameters observed were plant height (cm), leaf area (), length of cobs without husks (cm), diameter of cobs without husks per plant (mm), weight of cobs with husks (g), weight of cobs without husks ( g), cob weight per plot (kg). Based on the research results, it can be concluded that providing various kinds of foliar fertilizers has a good effect on the growth and yield of baby corn plants (Zea may L. var. saccahara Sturt). Bayfolan foliar fertilizer () which produces a plant height of 93,12 cm, leaf area of ​​1442,40 ,length of cob without husks 12,40 cm, diameter of cob without husks per plant 15,24 mm, weight of cob with husks 31,80 g, weight of cob without husks 21,00 g and weight of cob per plot 2.307 kg.

This research aims to examine the effect of planting density on the growth and yield of mung bean plants (Vigna radiata L.). This research was carried out in the Research Garden of the Faculty of Agriculture, Tridinanti University, located in Pulau Semambu, North Indralaya, Ogan Ilir, South Sumatra, from September 2023 to October 2023. The research design used a Randomized Block Design (RBD) with 4 (four) treatments and 6 (six) replications. The number of plants studied in the experimental unit was 3 (three) sample plants. The treatments studied were J1 with planting density = 40 cm x 15 cm, J2 = 40 cm x 20 cm, J3 = 40 cm x 25 cm, and J4 = 40 cm x 30 cm. The parameters observed were plant height, flowering age, number of pods per plant, number of pods per plot, pod weight per plant, pod weight per plot, seed weight per plant and yield.  Based on the results of the research that has been carried out, it can be concluded that the planting density (40 cm x 20 cm) had a good affected on the growth and yield of mung bean plants, namely producing a plant height of 19.28 cm at 40 days after planting, flowering age of 41.73 days, number of pods per plant 6.89, number of pods per plot 140.83, weight of pods per plant 8.50 g, pods per plot 153.83 g,  weight of seeds per plant 7.78 g with production results 933,6 kg/ha.

Oil palm is one of the plantation commodities that has an important role in activities in Indonesia. The purpose of this study was to study the combination and efficiency of NPK fertilizer added with liquid organic fertilizer from banana weevil mole to oil palm seedlings. The research was carried out in smallholder estate of Keramasan Karyajaya Village, Kertapati Sub district of South Sumatra from May 2019 to December 2019. The experimental design used was a Randomized Block Design, 5 arrangements with 4 replications and each processing unit consisted of 5 plant samples. The treatments are (P): P0 = 334 g of NPK-1 seedlings (15-15-15) + without liquid organic fertilizer; P1 = 334 g NPK seed-1 (15-15-15) + 800 ml seed-1; P2 = 334 g NPK seed-1 (15-15-15) + 1600 ml seed-1; P3 = 167 g NPK seed-1 (15-15-15) + 800 ml seed-1; P4 = 167 g NPK seed-1 (15-15-15) + 1600 ml seed-1. The oil palm seedlings used in the PPKS 718 variety (DxP) are opened in 3-4 months which are normal and uniformly selected from the pre-nursery. The observed variables were plant seedling height (cm), number of leaves (strands), stem diameter (mm), chlorophyll content (mg cm-2) at 3-8 BSP using SPAD-502 plus chlorophyll meters, indicating abnormal seedlings. Data obtained were tested using analysis of variance, and 5% discussion. Provision of NPK compound fertilizer added with liquid organic fertilizer from mole weevil mole does not affect the parameters of plant height, number of leaves and stem diameter, but it is significantly affected by the level of greenness of the leaves. Giving NPK compound fertilizer with a dose of 167 g seeds-1 plus liquid organic fertilizer from mole weevil banana 800 ml seed-1 dose gives better results seen from the parameters of plant height, number of leaves, stem diameter and the level of greenness of leaves 2 months at a time ( BSP).

This study aims to identify the weeds that dominate the growth of glutinous  corn  (Zea mays ceratina). The research was carried out in the experimental garden of Tridinanti University Palembang in Semambu Village Indralaya Ogan Ilir Palembang City, South Sumatra from August 2020 to October 2020. This study used a quadratic method with 5 experimental plots, weed samples were taken 2 times, in the first month and the second month. The results of the SDR calculation carried out showed that in the first month the weeds that had the highest SDR value or dominated the growth were Amaranthus retroflexy L. (25.22%), while in the second month the highest SDR value was Digitaria sangunialis (L.) Scop (25.4%).
