Lantur Tumiang — 2026-09-07

This study was conducted in Dusun Asong, Aur Sampuk Village, Sengah Temila Subdistrict, Landak Regency, from June to August 2024, and aimed to evaluate the effect of oil palm solid waste application on the growth and yield of purple eggplant (Solanum melongena L.) grown on Red-Yellow Podzolic soil. A Randomized Block Design (RBD) with a single factor was used, consisting of six dosage levels of oil palm solid waste repeated four times, with three sample plants for each replication, so that a total of 72 plants were observed. The treatments were S0 (control, without solid waste), S1 (20 g/polybag), S2 (30 g/polybag), S3 (40 g/polybag), S4 (50 g/polybag), and S5 (60 g/polybag). The results showed that the application of oil palm solid waste had a highly significant effect on plant height, fruit length, fruit diameter, number of fruits, and fruit weight. The highest values for all observed variables were obtained in treatment S5, with plant height of 70.50 cm, fruit length of 20.08 cm, fruit diameter of 3.10 cm, number of fruits of 1.50, and fruit weight of 59.00 g.

Ilham — 2026-09-07

This study was conducted in Kalinilam Village, Ketapang Regency, from May to July 2024, and aimed to evaluate the effect of KCl fertilizer dosage on the growth and yield of sweet corn (Zea mays saccharata Sturt.) grown on Alluvial soil. A Randomized Block Design (RBD) with a single factor was used, consisting of six dosage levels of KCl fertilizer repeated four times, with three sample plants for each replication, so that a total of 72 plants were observed. The treatments were K0 (control, without KCl), K1 (2 g/polybag), K2 (2.5 g/polybag), K3 (3 g/polybag), K4 (3.5 g/polybag), and K5 (4 g/polybag). The results showed that the application of KCl fertilizer had no significant effect on plant height, number of leaves, cob length, cob diameter, and cob weight per plant. The highest average values for all observed variables were nevertheless obtained in treatment K5, with plant height of 224.17 cm, number of leaves of 8.91 strands, cob length of 21.13 cm, cob diameter of 5.12 cm, and cob weight per plant of 98.75 g

Pengaruh Pemberian Ekstrak Daun Kelor (Moringa oleifera) terhadap Pertumbuhan dan Hasil Tanaman Pakcoy (Brassica rapa L.) di Tanah Podsolik Merah Kuning

Stefanus Ilwan — 2026-09-07

This study was conducted in Jawa Tengah Village, Ambawang Subdistrict, Kubu Raya Regency, from April to July 2025, and aimed to evaluate the effect of Moringa (Moringa oleifera) leaf extract application on the growth and yield of pakcoy (Brassica rapa L.) grown on Red-Yellow Podzolic soil. A Completely Randomized Design (CRD) with a single factor was used, consisting of six concentration levels of Moringa leaf extract repeated four times, with three sample plants for each replication, so that a total of 72 plants were observed. The treatments were M0 (control, without extract), M1 (35 mL/L/plant), M2 (40 mL/L/plant), M3 (45 mL/L/plant), M4 (50 mL/L/plant), and M5 (55 mL/L/plant). The results showed that Moringa leaf extract had a highly significant effect on the number of leaves, but had no significant effect on plant height, plant fresh weight, and root volume. The highest number of leaves was obtained in treatment M5 (15.25 strands), the highest plant height was obtained in treatment M4 (26.75 cm), while the highest fresh weight and root volume were obtained in treatment M2 (98.75 g and 7.25 mL, respectively)

Pengaruh Pemberian Dosis Legin terhadap Pertumbuhan dan Hasil Kedelai Edamame (Glycine max L. Merrill) di Tanah Podsolik Merah Kuning

Priwartono Eko Saputro — 2026-09-07

This study was conducted in Jawa Tengah Village, Ambawang Subdistrict, Kubu Raya Regency, from April to July 2025, and aimed to evaluate the effect of Legin biofertilizer dosage on the growth and yield of edamame soybean (Glycine max L. Merrill) grown on Red-Yellow Podzolic soil. A Completely Randomized Design (CRD) with a single factor was used, consisting of six dosage levels of Legin repeated four times, with three sample plants for each replication, so that a total of 72 plants were observed. The treatments were L0 (control, without Legin), L1 (5 g/100 g seed), L2 (7.5 g/100 g seed), L3 (10 g/100 g seed), L4 (12.5 g/100 g seed), and L5 (15 g/100 g seed). The results showed that Legin application had no significant effect on plant height, number of leaves, number of pods, and pod weight. The highest average values for plant height, number of leaves, and number of pods were obtained in treatment L4 (43.00 cm, 20.00 strands, and 37.75 pods, respectively), while the highest pod weight was obtained in treatment L5 (81.25 g).

Pengaruh Pemberian Kotoran Burung Walet terhadap Pertumbuhan dan Hasil Tanaman Sawi Hijau (Brassica juncea L.) pada Tanah Podsolik Merah Kuning

Dedek Muryadi — 2026-09-07

This study was conducted in Nanga Yen Village, Hulu Gurung Subdistrict, Kapuas Hulu Regency, from May to July 2024, and aimed to evaluate the effect of swiftlet (walet) manure application on the growth and yield of green mustard (Brassica juncea L.) grown on Red-Yellow Podzolic soil. A Randomized Block Design (RBD) with a single factor was used, consisting of six dosage levels of swiftlet manure repeated four times, with three sample plants for each replication, so that a total of 72 plants were observed. The treatments were L0 (control, without swiftlet manure), L1 (20 g/polybag), L2 (25 g/polybag), L3 (30 g/polybag), L4 (35 g/polybag), and L5 (40 g/polybag). The results showed that the application of swiftlet manure had a highly significant effect on plant height, number of leaves, and fresh weight of the plant, but had no significant effect on leaf width. The highest average plant height was recorded in treatment L3 (44.83 cm), the highest number of leaves and fresh weight were recorded in treatment L5 (8.50 strands and 145.92 g, respectively), while the widest leaf width was obtained in treatment L4 (10.08 cm).
