Abstract

This study aimed to determine the effect of market waste-based liquid organic fertilizer (LOF) on the growth and production of water spinach (Ipomoea reptans Poir), as well as to determine the best concentration for optimal results. The study was conducted at the Green House of FMIPA UPG 1945 NTT, Oebobo District, Kupang City, East Nusa Tenggara, from November 2025 to January 2026 using a Randomized Block Design (RBD) consisting of five treatments and five replications. The treatments consisted of P0 (control), P1 (25 ml/L water), P2 (50 ml/L water), P3 (75 ml/L water), and P4 (100 ml/L water). The observed variables included plant height, leaf length, number of leaves, and fresh weight. Data were analyzed using Analysis of Variance (ANOVA) followed by the Least Significant Difference (LSD) test at a 5% significance level. The results showed that the application of market waste-based liquid organic fertilizer had a highly significant effect on all growth and production parameters of water spinach. The best treatment was obtained in P4 (100 ml/L water), resulting in the highest plant height (36.4 cm), leaf length (15 cm), number of leaves (11.8 leaves), and fresh weight (3.12 g). Therefore, market waste-based liquid organic fertilizer is effective in improving the growth and production of water spinach and has the potential to become an environmentally friendly and economical fertilizer alternative.

Abstract

This study was conducted over a three-month period, from November 2025 to January 2026, at the FMIPA UPG 1945 NTT greenhouse in Oebobo District, Kupang City. The research aimed to determine the effect of applying Plant Growth-Promoting Rhizobacteria (PGPR) liquid organic fertilizer on the growth and yield of lettuce (*Lactuca sativa* L.) and to identify the most effective dosage. A Completely Randomized Design (CRD) was employed, featuring five treatments and six replications. The treatments consisted of P0 (control without PGPR), P1 (150 ml/liter of water), P2 (250 ml/liter of water), P3 (350 ml/liter of water), and P4 (450 ml/liter of water). Observed parameters included plant height, number of leaves, and fresh weight of the lettuce plants. Data were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test at the 5% level. The results indicated that the application of PGPR liquid organic fertilizer had a highly significant effect on lettuce growth and yield. The best results were obtained with a dosage of 450 ml/liter of water (P4), yielding an average plant height of 24.80 cm, 22.50 leaves, and a fresh weight of 134.67 grams. The enhanced plant growth is attributed to the ability of PGPR to increase nutrient availability, improve soil biological conditions, and produce growth hormones such as auxins, gibberellins, and cytokinins. Thus, the use of PGPR liquid organic fertilizer offers an environmentally friendly bio-fertilizer alternative for sustainably increasing lettuce productivity.

Abstract

This study aimed to determine the effect of cow manure application on the growth of cayenne pepper (Capsicum frutescens L.) and to identify the most effective dosage for optimal plant growth. The research was conducted at the Biology Greenhouse, Faculty of Mathematics and Natural Sciences, Universitas Persatuan Guru 1945 NTT, Kupang, from January to March 2026. An experimental method was employed using a Completely Randomized Design (CRD) consisting of four treatments and five replications, resulting in 20 experimental units. The treatments were A0 (soil without cow manure), A1 (soil + cow manure at a ratio of 1 kg : 1 kg), A2 (soil + cow manure at a ratio of 1.5 kg : 0.5 kg), and A3 (soil + cow manure at a ratio of 0.5 kg : 1.5 kg). The observed parameters included plant height and number of leaves. Data were analyzed using Analysis of Variance (ANOVA) followed by the Least Significant Difference (LSD) test at a 5% significance level. The results showed that the application of cow manure significantly affected the growth of cayenne pepper plants. Treatment A1 produced the best growth performance, with an average plant height of 18.18 cm and an average leaf number of 17.53 leaves. The increase in plant growth was attributed to the availability of essential macronutrients such as nitrogen, phosphorus, and potassium, which play important roles in tissue formation, photosynthetic activity, and vegetative development. In addition, cow manure improved the physical, chemical, and biological properties of the soil, thereby enhancing nutrient availability and uptake by plants. Based on the findings, it can be concluded that cow manure application positively influenced the growth of cayenne pepper plants, with treatment A1 providing the most effective dosage for optimal growth.

Abstract

This research was conducted in Oesapa Selatan Village, Kelapa Lima District, Kupang City, East Nusa Tenggara, in November–January 2026. The research aimed to determine the effect of providing fermented tofu dregs with different doses in feed on the growth of African catfish (Clarias gariepinus), and to determine the dose that provided the best growth results. The research method used a Completely Randomized Design (CRD) with four treatments and four replications to obtain 16 experimental units. The treatments given included P0 (100 g of commercial Hi-Pro-Vite feed without fermented tofu dregs), P1 (10 g of fermented tofu dregs), P2 (15 g of fermented tofu dregs), and P3 (20 g of fermented tofu dregs). The parameters observed included weight gain, body length gain, specific growth rate (SGR), and survival rate (SR). Observations were carried out every 10 days for 40 days of maintenance. Data were analyzed using Analysis of Variance (ANOVA), and if significant differences were found, the Least Significant Difference (LSD) test was performed at the 5% level. The results showed that the provision of fermented tofu dregs significantly affected the growth and survival of African catfish. Treatment P2 (15 g fermented tofu dregs) provided the best results, with the highest weight gain, length gain, SGR, and SR compared to other treatments.
