Abstract

Rapid population growth and increasing demand for high-quality food drive the need for innovation in the agricultural sector. The main challenge faced is how to enhance production efficiency and the quality of agricultural yields sustainably. Pak choi, one of the fast-growing crops in Indonesia, requires special attention through various innovations to support its optimal growth. One of the key factors in pak choi growth is fertilization. However, the continuous use of synthetic fertilizers can damage soil fertility. As a sustainable alternative, Liquid Organic Fertilizer (LOF) has been developed from recycled green waste, specifically Leucaena leaves and pineapple peels. This study aims to evaluate the effects of LOF application derived from these organic waste materials on pak choi growth. This research was conducted in Sugih Waras Village, Belitang Mulya District, East OKU Regency. The research method used was a Completely Randomized Design (CRD) with 5 treatments and 3 replications. Data were analyzed using ANOVA and further tested with HSD at a 5% significance level. The results showed that the application of LOF had the best effect in the treatment was 45 ml LOF/polybag, with plant height reaching 21 cm, 23 leaves, root length of 15 cm, fresh plant weight of 116 grams, and dry plant weight of 12.1 grams.

Abstract

Red chili (Capsicum annum L.) is one of important horticultural crop and a leading commodity among 18 types of commercial vegetables cultivated in Indonesia. Red chili productivity is influenced by soil fertility, while chili plants in Lampung are generally planted on ultisol soil. Ultisol soil is a type of soil that is poor in the nutrients N, P, and K, and has soil acidity problems. One form of effort to improve ultisol soil is by applying fertilizer. This research aims to determine the response of growth and production of Akar and Lotanbar varieties of red chilies to the dose of NPK fertilizer applied, so that we can find out the dose of NPK fertilizer that can increase the growth and production of red chili plants. This research used a Randomized Block Design which was prepared factorial 2 x 4 with 3 repetitions. The data obtained were tested for homogeneity of variance using the Barlett test and the additivity of the data was tested using the Tukey test. If these two results meet the assumptions, the data is analyzed using analysis of variance, separating the middle value and then testing the middle value using the 5% BNT test. The research results show that the NPK fertilizer dose of 30 g/plant is the best dose that can increase the growth and production of red chili plants varieties Lotanbar and Akar, in general the response of chili plants to doses of NPK fertilizer is not influenced by plant variety or vice versa.Keywords : Red chili, ultisol, fertilizer, NPK, dose
