Abstract

Composting is a method of converting organic materials into simpler materials using microbial activity. The aim of the study was to determine the effect of adding different types of starter to the composting process of vegetable waste and garden waste. This study used a factorial completely randomized design, consisting of two factors. Factor 1: Type of Starter Material (S), consists of 3 levels S0: No starter, S1: EM4 (Effective Microorganisms) 20% + Urea 200 gr ; S2: MOL (POC Water Hyacinth) 20% + Urea 200 gr. Factor II: types of organic waste, L1: organic vegetable waste, and L2: Gardening organic waste. The results of the study on the treatment of starter types and types of organic waste in the composting process can be concluded as follows: Treatment of vegetable organic waste with starter types and types of waste, the final pH of composting in this study ranged from 7.67-7.94 with temperatures ranging from 27.0 – 28.3 0C, and the occurrence of volume shrinkage ranging from 61.48% to 95 has a C/N ratio of 14.24. - 18.75

Abstract

Black Soldier Fly (BSF) is a popular insect because of its role in breaking down organic waste into compost. The final stage of the larva (prepupa) separates from the growth medium making it easier to harvest. The residue of the propagation media is a mixture of the remaining organic matter with the larval skin resulting from the skin turnover into quality compost. This experiment aims to determine the effect of BSF residue compost on the growth and yield of spinach (Amaranthus Hybridus L); The experiment was carried out at the Green House and Laboratory of the Faculty of Agriculture, Wijaya Kusuma University, Surabaya, from March to July 2022. The factorial experiment, with the treatment of factor one was the composition of BSF waste compost which consisted of; P0 (soil : 100% compost : 0% soil without compost); P1 (soil: compost BSF household waste 75%: 25%); P2 (soil : compost BSF household waste 50% : 50%); P3 (soil: compost BSF fruit waste 75%: 25%); P4 (soil: BSF compost 50% fruit waste: 50%); while the second treatment factor is the application of urea fertilizer, namely: K0 without urea fertilizer; K1 was given 1.5 grams urea/plant ; K2 was given urea 3.0 g/plant. The results showed that there was an interaction between compost treatment and urea fertilizer treatment on spinach production. There was a significant difference between plants that were not given compost and plants that were treated with compost for the variables of consumption weight, total plant weight and root weight. Urea fertilizer treatment has a significant effect on spinach yield.

Abstract

This study aims to describe in depth the flow and management of circular tree pruning waste management to the management of urban parks in South Surabaya. This study uses a type of descriptive research with a qualitative approach. This research was conducted for six months from January to July 2024 and the research location focused on South Surabaya city parks and green lanes along Jl. A. Yani to Jl. Raya Darmo which are included in the South Surabaya area. Primary and secondary data sources. Data collection methods by interviews, documentation and observation. Data analysis uses triangulation analysis. The results of the study show that the management of city parks and green paths in South Surabaya produces tree pruning waste that is used as compost and distributed to city parks and green paths. The management of composting waste is an activity that aims to reduce organic waste and create environmentally friendly circular management. This management management strategy results in a good Green Open Space with fresh and green plants. Circular management activities provide benefits for city parks and green lanes in South Surabaya.
Substitution Effect Nutrient Hydroponic with POC Against Plant Growth mustard (Brassica rapa L.) in Hydroponics Wick System in Green House Ndau, Wensislaus Arman; Sa'adah, Tatuk Tojibatus; Indarwati, Indarwati; Setiawati, Anindya Prastiwi; Bafiqi, Medina Johana Pakula

Abstract

Hydroponics wick system is a hydroponic system by utilizing the wick to absorb water and nutrients by utilizing capillarity power. This axis serves to connect the nutrient solution in the tub with planting medium. This study aims to : (1) determine the effect of the mix AB nutrient on plant growth in hydroponic lettuce; (2) determine the effect of Liquid Organic Fertilizer on plant growth in hydroponic lettuce; (3) the effect of substitution of hydroponic nutrient with a liquid organic fertilizer on plant growth in hydroponic lettuce. This study uses a completely randomized design with 5 treatments and repeated 4 times, resulting in 20 experimental units. The results showed : (1) administration of 5 ml/l A and 5 ml/l B gives the best results in growth of mustard plants; (2) provision of 3 ml/l A and 3 ml/l B + 100 ml/l POC also gave a good response to the growth of mustard plants; (3) administration of 2ml/l A and 2 ml/l B + 150 ml/l POC also gave a good response to the growth of mustard.

Abstract

The research consists of two stages, the first being the development of LOF production from water hyacinth and banana peel applied to ginger plants. The purpose of the study is to determine the extent to which the application of liquid organic fertilizer (LOF) can enhance the early growth of ginger plants. The second is the cultivation of ginger plants by applying various types of LOF compared to ginger plants without LOF application. The research was conducted from the end of August to November 2025 in Banjar Poh Village, Sidoarjo District, Sidoarjo Regency.  Research hypothesis: (1) It is suspected that different LOF applications will result in different early growth in ginger plants, (2) it is suspected that the use of banana peel LOF provides better early growth in ginger plants compared to other treatments. The study used a Randomized Block Design (RBD) method with one factor consisting of 4 treatments. The treatment involved the provision of types of LOF, namely P1 = without LOF; P2 = LOF water hyacinth; and P3 = LOF banana peel P4 = EM4 (Effective Microorganisms 4). Each treatment was repeated 3 times, and each repetition had 3 plant samples. Observations of the early growth of ginger plants include shoot height, number of shoots, and number of leaves. The obtained data were analyzed using analysis of variance, and if there were significant differences, it was followed by the Least Significant Difference (LSD) test at 5%.

Abstract

This study aimed to evaluate the effect of various types of synthetic organic fertilizers on the growth and yield of upland water spinach (Ipomoea reptans). The research was conducted in open field conditions using a Randomized Complete Block Design (RCBD) with three treatments: P1: control (urea); P2: Nutrizim granular organic fertilizer; P3: Nutrizim crumb organic fertilizer, each replicated three times. (a) The use of synthetic organic fertilizers had a significant effect on growth parameters, including number of leaves, plant height, and fresh weight of upland water spinach. (b) The plants treated with Nutrizim granular fertilizer produced a fresh weight yield of 36.15 tons/ha, which was not significantly different from the control treatment (47.61 tons/ha), with a yield difference of 11.46 tons between the Nutrizim granular fertilizer and the control. Thus, the use of Nutrizim granular organic fertilizer can support the growth and yield of upland water spinach.
