Abstract

This study aims to determine the best interaction between watermelon varieties and the application of liquid organic fertilizer from fruit waste, the best dose, and the suitable varieties for cultivation on peat soils. The design used was a 4 x 2 factorial RCBD (Randomized Completely Block Design) with 3 replications. The factors studied arethe variety (V) consists of two levels, namely: V1: Amara F1, V2: Garnis F1, and liquid organic fertilizer (P), consists of four levels, namely: P0: 0/liter of water, P1: 30 mL +970 mL of water/plot, P2: 60 mL+940 mL of water/plot, P3: 90 mL+910 mL of water/plot. The results showed that there was no interaction between varieties and liquid organic fertilizers. The varieties had a significant effect on plant length, the number of leaves, flowering time, and fruit length. The suitable variety was Garnis F1. The liquid organic fertilizers had a significant effect on fruit weight per plot, and fruit diameter with the best dose of 30 mL+970 mL of water/plot on the Garnis F1 variety. The highest fruit sweetness rate (7.72 Brix) at the best dose 90 mL+910 mL of water/plot on the Garnis F1 variety

Abstract

There are several ways of cultivating crops that are applied by the community, namely: monoculture, insertion and agroforestry. Differences in the application and management of cropping patterns and the types of plants planted will have a different effect on microbes in the rhizosphere, especially fungi as biological agents. The purpose of this study was to determine the types of fungal biological agents found in the rhizosphere of several plants with different cropping patterns on peatlands. The location of the samples was determined purposively with insert cropping patterns (mustard-sweet corn), mono-culture (sweet corn) and agroforestry (jelutung-soursop). Testing the inhibition of biological agent fungi against Sclerotium rolfsii used a completely randomized design consisting of 7 treatments with 3 replications. The exploration results obtained 7 isolates of biologically active fungi that could inhibit S. rolfsii. The highest inhibition was shown by isolates JSk1 (origin from the rhizosphere of soursop plants), isolates J (origin from the rhizosphere of sweet corn) and JS1 (origin of the rhizosphere of mustard greens). JSk1 and J isolates had an inhibition close to 60%. The results of the identification of JSk1 isolates were the fungus Gliocladium sp1, isolate J the fungus Trichoderma harzianum with competitive inhibitory mechanisms, mycoparasites, antibiosis causing host hyphae to experience malformation, lysis and destruction.

Abstract

Peatland is a specific ecosystem that is always waterlogged and has multiple functions, including economic, hydrological, environmental, cultural, and biodiversity functions. Existing peatlands, especially in Central Kalimantan, have great biodiversity potential. This potential provides benefits for people living in peat areas. This diversity of biodiversity has the potential of medicinal plants that have not been maximally explored. Therefore, through this activity, data will be obtained regarding the types and potential of medicinal plants in inland peat areas, which will facilitate their management. This research activity was carried out in the “Handak Maju” IUPHKm area for 3 (three) months, from July – September 2022. The implementation method is carried out through survey activities and field observations and carrying out of the Focus Group Discussions, as well as related literature studies. Based on the results of the survey conducted, it was found that several types of medicinal plants have the potential to be developed and preserved. According to Zuhud (1991) that medicinal plants are plants whose plant parts (leaves, stems or roots) have medicinal properties and are used as raw materials in the manufacture of modern and traditional medicines. It was further revealed that, medicinal plants are still not widely cultivated. However, the advantages of treatment using traditional medicinal plant ingredients are generally considered safer than the use of modern medicine. This is because traditional medicine has relatively fewer side effects than modern medicine.
