“…It is suspected that the low dose given is appropriate for plants and is more effective in absorbing nutrients, in order to increase plant growth and development, so as to increase growth. According to Marpaung (2017) the application of liquid organic fertilizer must pay attention to the concentration or dosage that will be applied to plants. This supports the opinion of Yartiwi & Siagian (2017) stating that the application of POC to each plant with a different concentration will affect the size of the nutrient content in the fertilizer, but it is not certain that the larger the dose applied will further increase plant growth.…”

Scallion is one type of vegetable plant that is widely used as a flavouring or seasoning for dishes and other vegetable mixtures in several types of cuisine in Indonesia. For this reason, one of the efforts that can be made to increase the production of scallions in meeting the consumption needs of the community is by means of technical cultivation through the application of liquid organic fertiliser (LOF). The purpose of this study was to analyse the need for the right dose of LOF for scallions. This study used a non-factorial Randomised Group Design method by testing 6 treatment of LOF dose, namely: J1 = 1 ml/L water, J2 = 1.5 ml/L, J3 = 2 ml/L, J4 = 2.5 ml/L, J5 = 3 ml/L and J6 = 3.5 ml/L. Each treatment was repeated as many as 4 replications. The results from analysis of variance (ANOVA) showed that doses of LOF affected very significantly on the parameters of root length, root weight, wet stalk weight, and fresh shoot yield with the LOF dose of 1.5 ml/L water (J2) giving the best results.

“…Pupuk organik dapat berbentuk padat dan juga berbentuk cair. Pupuk organik cair mempunyai banyak manfaat diantaranya mempercepat pembentukan klorofil pada daun dan mempercepat pembentukan bintil akar pada tanaman polong-polongan yang dapat meningkatkan kemampuan fotosintesis pada tanaman dan pengikatan unsur nitrogen dari udara, dan beberapa manfaat lain pada tanaman (Marpaung, 2018). Hal ini juga didukung oleh penelitian mengenai kegunaan dari pupuk organik cair yang manfaatnya cepat bereaksi karena unsur-unsur didalamnya sudah terurai (Ginting, 2023).…”

Spinach is one of the most important needs for humans, but spinach production in Indonesia has decreased from year to year, so it needs improvement in terms of cultivation technology. The purpose of this study was to analyze the interaction between varieties of spinach and the dose of organic seaweed fertilizer on spinach production; analyzed the dose of organic seaweed fertilizer on spinach production and analyzed the effect of spinach varieties on spinach production. This study was arranged in a factorial randomized block design (RBD), which consisted of two factors, the first factor was the variety of spinach (b) which consisted of two levels, namely green spinach variety Giti Hijau (b1) and red spinach variety Giti Merah (b2), the second factor is the dose of organic fertilizer (d) which consists of 4 levels, namely control (d0), 2 mL/L water (d1), 3 mL/L water (d2), 4 mL/L water (d3). The treatment was divided into 3 blocks as repetition. Data analysis used ANOVA and follow-up test with a DMRT level of 5%. The results showed that the variety of spinach had a significant effect on plant height from 3 to 5 WAP, the number of leaves at 2 WAP and 3 WAP, and the fresh weight of spinach. Fertilizer dosage did not significantly affect plant height, number of leaves, root length, fresh weight, and dry weight of plants . There was no interaction between spinach varieties and doses of organic seaweed fertilizer on all growth parameters and production of spinach.

Kitchen waste, either the organic or the inorganic ones, accumulated on landfills causes environmental and health problems. Composting is an alternative that reduces environmental problems while producing Liquid Organic Fertilizers (LOF). This research was aimed to examine the LOF character made of organic kitchen waste from Darussalam Gontor University, Girls Campus. The research was conducted by composting 10 kg of kitchen waste (comprised of banana peel, rotten watermelon, and vegetable waste), 20 liters of rice washing water, 10 kg of eggshell, 1 kg of sugar, 1 liter of EM4 (decomposing microorganism), and 80 liters of water. The liquid fertilizer produced was analyzed physically, namely from the color, smell, and presence of insect larvae. Chemical analysis was carried out for the content of C-organic, organic matter N, P, and K). C-organic and other organic matter content were analyzed using the Walkley & Black method. Total N content was analyzed using the Kjeldahl method. The content of P and K were analyzed by the extraction method of HNO3 and HClO4. The liquid fertilizer produced was yellowish-brown in color, did not have a bad smell, and did not contain insect larvae. Its nutrient content, respectively C-organic, other organic matters, N, P, and K were 0.74%; 1.27%; 0.13%; 0.015%; and 0.10%. The fertilizer produced had not met the standards of the Ministry of Agriculture No. 261 of 2019. Further studies are needed with the addition of animal manure and the composition of the ratio of organic matter to water. Limbah organik dapur yang dibuang di tempat pembuangan akhir (TPA) menimbulkan permasalahan lingkungan dan kesehatan. Pengomposan sebagai salah satu alternatif mengurangi masalah lingkungan dari limbah organik dapur dan menghasilkan POC (Pupuk Organik Cair). Penelitian ini bertujuan untuk mengkaji karakter POC limbah organik dapur dari Universitas Darussalam Gontor Kampus Putri. Penelitian dilakukan dengan cara mengomposkan limbah dapur 10 kg (kulit pisang, semangka busuk dan limbah sayuran), air cucian beras 20 L, cangkang telur 10 kg, gula 1 kg, EM4 1 L dan air 80 L. POC yang dihasilkan dianalisa secara fisik (warna, bau dan kehadiran larva serangga) dan analisa kimia (kandungan C-organik, bahan organik, N, P dan K). Kandungan C-organik dan Bahan organik dianalisa dengan metode Walkley & Black. Kandungan N total dianalisa dengan menggunakan metode Kjeldhal. Kandungan P dan K dianalasi dengan metode ekstraksi HNO3 dan HClO4. POC yang dihasilkan berwarna coklat kekuningan, tidak berbau busuk dan tidak mengandung larva serangga. Kandungan unsur hara POC yaitu: C organik 0,74%; bahan organik 1,27%; N 0,13%; P 0,015%; K 0,10%. POC yang dihasilkan belum memenuhi standar Permentan No. 261 Tahun 2019, sehingga perlu kajian lebih lanjut dengan komposisi penambahan kotoran hewan dan komposisi perbandingan bahan organik dengan air.
