Abstract

Pepper (Piper nigrum Linn.) is the most traded spice commodity among other spices.  The problem with pepper farming in West Kalimantan is the lack of nutrient availability because plantation land is dominated by ultisol soils. Gamal leaf liquid organic diapers application is expected to increase the availability of nutrients in the growing media.  The aim of the study was to determine the nutrient content of the liquid organic diapers of gamal leaves, to see the effect, as well as the best concentration and time of application on the vegetative growth of pepper plants. The study was carried out for four months, namely from January to April 2020 at the Pepper Plantation of Tengon Village, using a factorial compeletely randomized design pattern consisting of 2 factors, the concentration such as 10%, 20%, 30%, 40% control and liquid organic fertilizer application time (every time week and every two weeks).  The results showed that liquid organic fertilizer of gamal leaves contained 12.7% C-organic., 0.27% N-Total., 47.03 C/N ratio., 0,25% P., and 0,29 K. The results of the research that giving Gamal leaf liquid organic fertilizer had a significant effect on shoot length, number of shoots and number of leaves of pepper plants, however, it did not significantly affect the time of emergence of pepper shoots. Liquid organic fertilizer concentration of 40% and time of application every week gave the best effect on shoot length (25.33 cm), number of shoots (4.33 shoots), and number of leaves (14.33 strands).  It was concluded that the  liquid organic diapers concentration treatment of gamal leaves had a significant effect on shoot length, number of shoots, and number of leaves of pepper plants but did not significantly affect the time of shoots emerging for pepper plants.  The best poc concentration that increases pepper plant growth is 40% with every week application.  It is recommended that further research can be carried out on the manufacture of  liquid organic diapers of gamal leaves combined with animal waste on the growth of pepper plants, with application time of 2-3 times in one week.

Abstract

Peanuts (Arachis hypogaea L.) are food crops that have high economic value because of their nutritional content. One of the factors that affect the low production of peanuts in West Kalimantan is the condition of the soil dominated by peat soil causing soil fertility to be low. Application of Rhizobium or legin is expected to increase the production of peanuts (Arachis hypogaea L.). The purpose of the research was to find out the effect of legin application against the amount of root nodules and the production of peanut plants. The research was conducted from November 2020 to February 2021. This research used a Completely Randomized Design (CRD) consisting of 5 treatments namely control, application of legin 4 g/kg seed, 8 g/kg seed, 12 g/kg seed and 16 g/kg seed. The results showed application of legin has a real influence on the total weight of root nodules, the total number of root nodules, the number of effective root nodules, the number of filling pods, the number of seeds and the weight of seeds, but had no noticeable effect on the time of flowering. Legin application of 12 grams / kg of seeds is the best concentration to increase the production of peanuts grown in west Kalimantan peat soil, because it gives the best results to the number of pods content 11.33 pods, the number of seeds 24.16 seeds and the seed weight 19.73 grams.

Abstract

Mungbean (Vigna radiata L.) is a palawija plant that is widely cultivated in Indonesia and includes glycophyte plants that are sensitive to salinity. Salinity stress can affect changes in morphological characters and growth in plants. The addition of gotu kola extract biostimulants can be a solution to reduce the effect of salinity stress on plants. This study aims to determine the effect and concentration of gotu kola extract biostimulant on the morphological and growth characteristics of mungbean plants experiencing salinity stress. This study used a completely randomized design (CRD) with 2 factors, namely NaCl concentration consisting of controls A1 (0‰), A2 (1.6‰), A3 (3.2‰), A4 (4.8‰) and A5 (6.4‰) as well as the concentration of biostimulants consisting of controls B1 (0mg/L), B2 (12.5mg/L), B3 (25mg/L), B4 (50mg/L) and B5 (100mg/L). Data were analyzed using ANOVA and continued with Duncan’s Multi Range Test with a 95% level of confidence. The results showed that the combination treatment of NaCl and gotu kola extract biostimulants had a significant effect on shoot fresh weight (grams), total fresh weight (grams), shoot dry weight (grams), total dry weight (grams), but had no significant effect on mungbean height. (cm), number of leaves (stalk), leaf area (cm2), root fresh weight (grams) and root dry weight (grams). Combination treatment of 3.2‰ NaCl and 25 mg/L biostimulant was the treatment that produced the best shoot dry weight and dry weight from the growth of mungbean plants experiencing salinity stress.

Abstract

Red onion is a rural commodity developed by people in West Kalimantan. The development of shallots in West Kalimantan is mostly completed in the formation of media in the form of peat soil with physical and substantive qualities that are unfit for the production of shallots. The application of Liquid Organic Fertilizer (LOF) is one method used to overcome the limitations of shallot cultivation on peatlands. The aim of the study was to determine the production of shallots of the Bauji variety influenced by a mixture of liquid organic fertilizer containing waste pineapple skin and water hyacinth. The study used an experimental method with a completely randomized design (CRD) and there were seven treatment standards for liquid organic fertilizer. The results of the study found that liquid organic fertilizer mixed with water hyacinth waste and pineapple peel had an effect on tuber wet weight, tuber dry weight, tuber number and tuber diameter. The best concentration is on. LOF treatment of 50 ml/L to increase the production of shallots of the bauji variety planted on peatlands in West Kalimantan. This treatment resulted in the highest tuber wet weight value of 55.07 grams and tuber dry weight of 15.22 grams, the number of tubers was 8 pieces and the tuber diameter was 2.44 cm.

Abstract

Eco-enzyme is a fermented product from an organic waste substrate, molasses, and water. Eco-enzyme can be used as antibacterial because it produces organic compounds such as alcohol and acetic acid. Pineapple peel waste (Ananas comosus L.) can be used as an eco-enzyme. This study aimed to test the antibacterial activity of pineapple peel eco enzyme against Pseudomonas aeruginosa and Staphylococcus epidermidis. The study used the method of determining the Minimum Inhibitory Concentration (MIC) and Minimum Killing Concentration (MBC) of pineapple peel eco-enzyme with 8 treatment levels namely negative control (aquadest), positive control (ciprofloxacin 5 mg/mL), 3.125%, 6.25 %, 12.5%, 25%, 50%, and 100% eco-enzymes. Based on the research results, it was known that the MIC value of pineapple peel eco-enzyme against P. aeruginosa, and S. epidermidis was 12.5% and 3.125%, respectively. Eco- enzymes from pineapple peel did not show minimum killing concentrations. Eco-enzyme of pineapple peel is only bacteriostatic towards the growth of P. aeruginosa and S. epidermidis bacteria.

Abstract

Acclimatization of black orchid plantlets (Coleogyne pandurata Lindl.) with cengkodok leaf extract biostimulant treatment has been successfully carried out, but still have slow growth. To support growth and development at the enlargement stage, cultivated orchids need to be given eco enzyme liquid organic fertilizer (LOF) derived from various sources of organic matter. Provision of ecoenzyme LOF combined with biostimulant 20 mg/l of Cengkodok leaf extract to increase the efficiency of nutrient absorption. The aim of the research was to find the best type and concentration of LOF for the growth of black orchids at the enlargement stage. The study used a Complete Randomized Design (CRD) with two treatment factors namely type of LOF (ecoenzyme (ee) LOF from vegetable and fruit waste, ee LOF from pineapple peel waste, and "NASA" LOF) and . the POC concentration (0; 0.5; 1.0; and 1.5 ml/l). The results showed that the single treatment of ee LOF significantly effected the number of leaves and the number of black orchid tillers, while the single treatment of ee LOF concentration had an effect on the parameters of height, number of leaves, number of tillers and leaf area of black orchid. The parameter of chlorophyll content had no signifcant effect by the type and concentration of LOF. The largest leaf area was shown in the addition of ee LOF from vegetable and fruit waste at a concentration of 1 ml/l which was 11.88 cm2.

Abstract

Pontianak siam orange (Citrus nobilis var. microcarpa) is an important agricultural commodity unique to Sambas Regency, West Kalimantan. The demand for Pontianak siam oranges has been steadily increasing over the years, yet the production of Pontianak oranges has not been able to meet the domestic demand. The limited availability of superior seedlings is one of the reasons for this situation. Therefore, efforts are needed to fulfill the demand for Pontianak siam oranges by producing a large quantity of superior seedlings in a short period. One of the strategies that can be employed is in vitro propagation. This research aims to observe the growth of Pontianak Siamese orange shoot explants after administration of NAA (Naphthalene Acetic Acid) and BAP (6-Benzyl Amino Purine). This research was conducted from January to June 2023 at the Tissue Culture Laboratory of the Department of Biology, Faculty of Mathematics and Natural Sciences, Tanjungpura University. The study employed a Completely Randomized Design (CRD) with two treatment factors namely NAA concentrations with 4 levels (0; 0.25; 0.5; 0.75 mg/L), and BAP concentrations with 5 levels (0; 0.5; 1; 1.5; 2 mg/L). Parameters observed were the emergence time of shoot, shoot number, height of shoot, and the number of leaves. The results showed that single NAA, single BAP, and combination treatment of NAA and BAP significantly affected all growth parameters. Treatment with the addition of 0.25 mg/L NAA and 1 mg/L BAP (A1B2) was the treatment with the fastest shoot emergence time (2.80 days after planting), the largest number of shoots (2.60 shoots)the tallest shoots (1.50 cm), , and the greatest number of leaves (2.60 leaves).
