Abstract

It is crucial to improve the shallot (Allium ascalonicum L.) cultivation system on peatlands to increase the growth and production of shallots. One is the provision of Biostimulants derived from Kirinyuh (Chromolaena odorata L.) extract. This study aimed to determine the effect of Kirinyuh (C. odorata) methanol extract on the growth and yield of shallot (A. ascalonicum) and to determine the best concentration and application time of Kirinyuh extract to increase the growth and yield of shallots. This research was conducted from September to December 2020 at the Biology Laboratory and Greenhouse Department of Biology, Faculty of Mathematics and Natural Sciences, Tanjungpura University, Pontianak. The study used a completely randomized (CRD) factorial pattern with two factors. The first factor was the concentration of Kirinyuh extract, which consisted of 5 treatments (0; 25; 50; 75, and 100 mg/L), and the second factor was application time which consisted of 2 treatments (1 week and two weeks). The results showed that the combination of Kirinyuh extract concentration and application time had a significant effect on wet shoot weight, dry shoot weight, tuber quantity, wet tuber weight, and tuber dry weight but had no significant effect on plant height, number of leaves, wet weight of roots, dry weight, root and tuber diameter. The concentration of Kirinyuh extract and the best application time was 100 mg/L with an application time of 2 weeks.

Abstract

The horticultural sector is growing and the need for its products is also increasing, including the need for green beans, but its availability is limited by land conditions that are poor in organic matter, so it needs to be treated with the addition of organic fertilizers such as vermicompost. This study aims to determine the effect of vermicompost and obtain the best dose for the growth and production of mung bean (Vigna radiata L.). The study was conducted using a factorial Completely Randomized Design (CRD) consisting of a single factor, namely the provision of vermicompost. From these factors, there were four levels of treatment (0, 5, 15, and 25 tons ha-1) and each treatment was given three replications so that there were 12 experimental units. The parameters reviewed were plant height, total productive branches, flower age, harvest age, total pods planted, percentage of pithy pods, weight of planted seeds, weight of seeds per plot, and weight of 100 seeds. The dose of vermicompost 25 ton.ha-1 was better than the dose of 0 ton.ha-1, the dose of 5 ton.ha-1, and the dose of 15 tons/ha. The treatment can increase plant height, total productive branches, total pods planted, percentage of pithy pods, weight of seeds planted, weight of seeds per plot, and weight of 100 seeds.

Abstract

Cutleaf groundcherry (Physalis angulata L.) is a plant that belongs to the Solanaceae family. In Indonesia, this plant grows spread in various regions and has different names in each region. However, this plant is rarely cultivated and is generally considered a weed by farmers. Recently many studies have shown that cutleaf groundcherry contains many substances that are beneficial for the health sector, so it has the potential to be developed as a cultivation plant for exotic fruit sources that function as nutraceuticals. Plant breeding programs can be a solution in responding to these problems. As the first step in developing cutleaf groundcherry through a breeding program, the Plant Breeding Laboratory, Faculty of Agriculture, Brawijaya University, collected accessions of cutleaf groundcherry from various regions in Indonesia. The phonological stage of its growth is one piece of information that is useful in better understanding the cutleaf groundcherry life cycle and, as a result, simplifying cutleaf groundcherry cultivation management. This research aims to provide practical knowledge on the cutleaf groundcherry life cycle to develop a more efficient plant management approach for cultivation, including plant breeding initiatives. The BBCH scale was used to make observations (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie). The descriptive statistics obtained from observations and presented in descriptive narrative form using the BBCH scale with 3-digit coding numbers and documentation images were used in the data analysis. The results showed that the BBCH scale was used to define and describe cutleaf groundcherry phenology, which included germination (stage 0), leaf development (stage 1), side shoot formation (stage 2), the emergence of inflorescence (stage 5), flowering (stage 6), fruit development (stage 7), fruit and seed ripening (stage 8) and senescence (stage 9)

Abstract

Black orchid plantlets have a relatively slow growth at the acclimatization stage. The growth of black orchid plantlets can be increased by giving biostimulants. Biostimulants are bioactive compounds, and when they are applied, they can increase plant growth. This study aims to determine the effect of biostimulant Gotu kola extract (Centella Asiatica L.) on the growth of black orchid plantlets (Coelogyne Pandurata Lindl.) at the acclimatization stage. The research was conducted at the Biology Department's greenhouse from September until December 2020. The study used a completely randomized design with a factorial pattern. The first factor is the concentration of biostimulants consisting of 5 levels, e.g: 0 mg/L; 25 mg/L; 50 mg/L; 75 mg/L; 100 mg/L. The second factor is the application time which consists of 2 levels: once a week and once every two weeks. The results showed that the application of biostimulant Gotu kola extract had no significant effect on plantlet height, leaf length, leaf width, number of leaves, number of tillers, and number of plantlet roots of black orchid in the acclimatization stage.

Abstract

Central Kalimantan has a typical peatland habitat which is dominated by Kelakai (Stenochlaena palustris). Various kinds of plants from the Kelakai genus are, for example, the Stenochlaena genus, but the benefits are less known, namely Kelakai. Kelakai is a plant that has clearly visible main characteristics such as stems, roots and leaves. The purpose of this study was to analyze the botanical composition and potency of Kelakai growing on peatlands of Central Kalimantan as a medicinal plant. This research method was an exploratory method supported by laboratory experiments which aimed to determine its potential as a medicinal plant and wound epithelialization under controlled conditions. The data on the botanical composition of Kelakai were analyzed using descriptive analysis, where the sample was obtained by purposive random sampling, while the potency data was analyzed using the Oneway Anova test and then Duncan's 1% test was performed. The wound is on the abdomen 2 cm long. The treatment given was applying Kelakai extract gel with different concentrations on a regular basis every day for 3 days. The results showed that Kelakai on peat swamp land in Central Kalimantan was the most dominant, so it can be concluded that its botanical composition can be a source of forage. The nutritional content of the Kalakai swamp green is quite high, so the Kelakai leaf extract gel has proven potential and can be recommended as an effective wound healing drug at a concentration level of 35%, with the optimal concentration in wound healing at a concentration level of 40%.

Abstract

The purpose of this study was to determine the effect of liquid organic fertilizer in increasing the growth of red chili pepper plants because inorganic fertilizers utilization was widespread among farmers. Thus, the idea emerged for the application of liquid organic fertilizers. The application time and place of liquid organic fertilizer were carried out in the experimental field of STIPER Sawahlunto Sijunjung. The design used was a Randomized Block Design (RAK) with five levels of treatment and five groups in order to obtain 25 experimental units. The application of market waste POC on red chili pepper plants has not significantly affected the growth of red chili pepper plants. Treatment of market waste POC at a concentration of 500 (ml/L) is the optimal dose/dose for increasing the number of leaves by 115 strands (control 63 strands) and the increase in plant height by 71.40 cm (control 55.40 cm). In general. POC applications of market waste are still unable to achieve optimal growth and yields, and this is because there is no addition of nutrients to plants to support growth.

Abstract

Peatlands are formed from piles of trapped plant residues, obstructing their decomposition process. The organic matter decomposition process certainly involves soil microbes. This study aims to determine the biological characteristics of peat soil after incubation with vermicompost. This research was conducted at Kampung Perlabian Village, Kampung Rakyat Sub-district, South Labuhanbatu Regency, North Sumatra. Soil biological analysis was conducted in the soil biology laboratory, Faculty of Agriculture, University of North Sumatra. This study used a non-factorial Randomized Block Design (RAK) with three treatments: P0 (control), P1 (1 kg peat soil + 500-gram vermicompost), and P2 (1 kg peat soil + 1 kg vermicompost). The results showed that adding vermicompost fertilizer to peat soil with treatment two could increase the total bacteria by 6.17 x 106 cfu/ml and the total fungus by 8.8 x 105cfu/ml, and CO2 respiration by 4.125 (mg CO/day). As a result, the soil's microorganism's activity is a process in which microorganisms live and do activities in a soil mass.

Abstract

This study aimed at examining the analysis of the soil quality index of dry land use on dry land in Blang Bintang District, Aceh Besar District. This research was conducted using a descriptive method based on the results of surveys and field observations as well as laboratory analysis. General biophysical conditions of the area and physical and chemical characteristics of the soil obtained from observations and indicators of soil quality through soil analysis in the laboratory. Soil sampling points were determined using the purposive sampling method, namely the points that have been determined on selected dry land in Blang Bintang District, Regency of Aceh Besar. The moderate soil quality index in the upland land use type is one of the reasons for the sampling of the Inceptisol soil type in the Blang Bintang sub-district, which has less fertile soil characteristics. Upland land use is the percentage of sand (57%) which is greater than the percentage of dust (36%) and clay (6%). This can be seen in the low content of C-organic (1.19), H2O, K-dd, P-available and N-total and high volume weight (1.34).
