Cat whiskers are traditional medicinal plants with bioactive compounds like flavonoids like sinensetin. The development of cat whiskers as a medicinal plant is still constrained by the quality of the simplisia. Fertilization and harvesting are essential aspects of the cultivation of medicinal plants. The research aims to determine the proper fertilization and harvest rotation time differences to produce biomass production and bioactive compound simplisia in cat whisker leaves. The method used was a Randomized Complete Block Design composed of two factors. The first factor was harvest rotation, consisting of four and six levels. The second factor was fertilization, composed of three levels, namely 100 g Indigenous Arbuscular Mycorrhizal Fungi (AMF) inoculum, 2.1 g Urea (N fertilizer) & 2.7 g SP-36 (P fertilizer), and a combination of 100 g Indigenous AMF inoculum + 2.1 g Urea (N fertilizer) & 2.7 g SP-36 (P fertilizer). The results showed that the highest simplisia biomass production was obtained by giving a combination fertilizer (Indigenous AMF, N & P). In contrast, the highest simplisia bioactive compound production was obtained with indigenous Arbuscular Mycorrhizal Fungi (AMF) fertilizer or a combination fertilizer (Indigenous FMA, N & P). Production of biomass and bioactive compounds of cat whisker plants simplisia can be done by harvesting earlier every four weeks or extending the harvesting time to every six weeks.

Kailan (Brassica olerace L.) is one of the popular vegetables in Indonesia. Vegetable cultivation should use environmentally friendly fertilizers, such as cow manure and banana waste liquid organic fertilizer (BWLOF). This study aims to analyze kailan's growth and production responses with differences in concentration and dose in liquid organic fertilizers from banana waste and cow manure, respectively. This study used a factorial Randomized Complete Block Design (RCBD) consisting of 2 factors, namely banana waste liquid organic fertilizer (BWLOF) with concentrations of 0, 20, and 40 ml L-1 and cow manure (K) with doses of 0, 127, and 200 g polybag-1. The results of the orthogonal polynomial test showed that the optimum concentration of BWLOF for kailan was 12.4 ml L-1, and the results of the DMRT test showed that a dose of 200 g polybag-1 of manure was the best treatment to increase the growth of kailan. The conclusion of this study showed that the provision of BWLOF significantly increased the root length and total dry weight of kailan plants. The provision of cow manure significantly increased plant height, number of leaves, stem diameter, leaf area, root length, and fresh and dry weight in the crown and roots, including the root crown ratio. However, there was no interaction between BWLOF and cow manure, which suggests that their combined use may not necessarily lead to synergistic effects.

Zeolite is a mineral widely used in agriculture due to its properties as an adsorbent, molecular sieve, and ion exchanger, as well as its high cation exchange capacity and selectivity. This study aims to analyze the effects of different zeolite application levels in the growing medium on the growth and yield of green mustard (Brassica juncea L.). The research was conducted in the smart agricultural sector of Gunadarma University Technopark from March to June 2024. A Randomized Complete Block Design (RCBD) with a non-factorial approach was employed, utilizing a single indicator plant—green mustard. The planting media consisted of soil, chicken manure, and cocopeat in a 1:1:1 ratio as the control. Zeolite was incorporated at three different levels: 40%, 45%, and 50%. Each treatment included ten repetitions with six samples, resulting in a total of 240 experimental units. The findings indicate that the optimal zeolite application level for green mustard growth is 45%, producing a plant yield of 17.75 tons per hectare. This represents a 5% improvement in efficiency compared to previous studies, which suggested that 50% zeolite was optimal. Additionally, the 45% zeolite treatment demonstrated a significant yield increase compared to the control treatment, which produced only 8.32 tons per hectare. These results highlight the potential of zeolite to enhance soil fertility and improve crop productivity.
