Abstract

This research aims to determine the effect of varieties and weeding time on the growth and varieties of sorghum plants. This research uses a factorial randomized block design (RAK) with 2 factors, the first factor is the use of varieties (V) with 3 levels, namely V1(numbu), V2(kawali ), V3 (super) and the second factor of weed weeding time (W) with 4 levels, namely W1(7 DAT), W2(14 DAT), W3(21 DAT), W4(28 HST). This research was carried out. This research was carried out in the experimental garden of Samudra University, Langsa City, Aceh Province with an altitude of ± 10 m above sea level. The research was carried out for 4 months which was carried out from June 2022 to September 2022. This research used a Randomized Block Design (RAK) pattern. factorial which consists of 2 factors, the first factor is the use of varieties (V) which consists of 3 levels, namely: V1 = Numbu, V2 = Kawali, V3 = Super. The second factor is weed weeding time (W) which consists of 4 levels, namely: W1 = 7 HST, W2 = 14 HST, and W3 = 21 HST, W4 = 28 HST. The parameters measured were plant height, stem diameter, number of leaves, panicle length, wet panicle weight, dry panicle weight, seed weight per plot

Abstract

ABSTRAKPenelitian ini dilakukan bertujuan untuk mengetahui pengaruh pemberian probiotik pada media pemeliharaan terhadap kualitas air dan pertumbuhan benih ikan baung (Mystus nemurus). Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap dengan 4 perlakuan 3 ulangan. Perlakuan yang diberikan adalah perbedaan jumlah probiotik yang ditambahkan yaitu yang terdiri dari perlakuan tanpa penambahan probiotk, perlakuan dengan penambahan probiotik sebanyak 0,5 ml/L, 1 ml/L, 1,5 ml/L. Hasil penelitian menunjukkan bahwa kualitas air pada masa penelitian tidak berpengaruh dan menghasilkan pertumbuhan panjang mutlak 6,30 cm, pertumbuhan berat mutlak 7,60 gr, survival rate 100%, laju pertumbuhan spesifik 4,78% dan rasio konfersi pakan 3,3%. Kata kunci : Ikan baung, kualitas air, probiotik. ABSTRACTThis research was conducted to find out the effect of probiotics administration on maintenance media on water quality and growth of baung fish seed (Mystus nemurus). The design used in this study was a Complete Randomized Design with 4 treatments of 3 repeats. The treatment given is the difference in the amount of probiotics added that consists of treatment without the addition of probiotk, treatment with the addition of probiotics as much as 0.5 ml / L, 1 ml / L, 1.5 ml / L. The results showed that water quality during the study had no effect and resulted in absolute long growth of 6.30 cm, absolute weight growth of 7.60 gr, survival rate of 100%, specific growth rate of 4.78% and feed confetti ratio of 3.3%. Keywords: Baung fish, water quality, probiotics.

Abstract

Sweet corn productivity is strongly influenced by cultivation techniques, particularly plant spacing and the number of seeds per planting hole. This study aims to analyze the effects of plant spacing and the number of seeds per planting hole on the growth and yield of sweet corn (Zea mays saccharata Sturt). A quantitative approach was employed using a factorial Randomized Block Design with two treatment factors. The first factor was plant spacing, consisting of three levels: J1 = 50 cm × 25 cm, J2 = 60 cm × 25 cm, and J3 = 80 cm × 25 cm. The second factor was the number of seeds per planting hole, consisting of three levels: B1 = one seed, B2 = two seeds, and B3 = three seeds. The study was conducted from April to June 2025 at the Experimental Field of the Faculty of Agriculture, Universitas Samudra. Data were collected through direct observation and measurement of plant height, number of leaves, stem diameter, cob length, cob weight, cob weight without husk, and production per hectare. The data were analyzed using analysis of variance followed by the Least Significant Difference test. The findings indicate that plant spacing had a highly significant effect on plant height, cob length, cob weight, cob weight without husk per sample, cob weight without husk per plot, and production per hectare, but had no significant effect on the number of leaves and stem diameter. The best plant height was obtained from J3, whereas most yield parameters were best obtained from J2. The number of seeds per planting hole had a highly significant effect on all observed parameters, with B1 producing the best results. The interaction between plant spacing and number of seeds per planting hole significantly affected plant height at 30 and 45 days after planting and cob weight. The best plant height was obtained from J3B1, while the best cob weight was obtained from J2B1. This study concludes that the use of one seed per planting hole combined with appropriate plant spacing can improve sweet corn growth and yield. These findings provide practical implications for optimizing cultivation strategies to enhance sweet corn productivity.
