Peatland is one type of wetland ecosystem that has a low fertility level. Efforts that can be made to increase the nutrient content of peat soils are adding organic fertilizers. Palm Oil Mill Liquid Waste (LCPKS) is one of the organic fertilizers that has a high organic matter content. LCPKS contains a number of nutrients : N, P, K, Ca and Mg. The research method used was experimental with a completely randomized design. The treatment consisted of giving LCPKS with a dose of: 0 mL/polybag (L1); 100 mL/polybag (L2); and 200 mL/polybag (L3) repeated 5 times. Parameters observed consisted of soil pH before and after adding LCPKS, stem diameter, number of leaves, plant height and root dry weight. Based on the results of analysis of variance, LCPKS administration had a significant effect on plant height, stem diameter, number of leaves and pH value. The results of the BNT test showed that giving LCPKS 200 mL/polybag gave the best results on all observation parameters.

Sugarcane (Saccharum officinarum L.) is an important commodity as the main ingredient for sugar production. Good sugarcane growth will produce high sugar yields so that sugar production also increases. Seed maintenance is one of the important stages in preparing good plants, especially fertilization. Oil palm empty fruit bunches residual mushroom (TKSJ) are one of the solid wastes produced from processing palm oil mills and can be used as an organic fertilizer. The purpose of this study was to determine the effects of giving TKSJ on the growth of sugarcane seedlings in peat soil media. This study used a completely randomized design (CRD) consisting of 5 treatments and 5 replications, namely without TKSJ compost (K0); TKSJ 25% (K1); TKSJ 50% (K2); TKSJ 75% (K3) and TKSJ 100% (K4). Observation parameters consisted of leaf length (cm) and root wet weight (g). The data were analyzed by Analysis of Variance (ANOVA). If it has a significant effect, then it is continued with Duncan's Multiple Range Test (DMRT) at a level of 5%. The results showed that composting

ABSTRAC Provision of seeds with the single bud chips method has the benefit of being more efficient in reducing the area of the nursery. In order to support the growth of single bud chips sugarcane seedlings in nurseries, bamboo root PGPR was given which made it easier for P to dissolve in the soil so that it was easily absorbed by plant roots. P element in the soil is needed by plants to meet plant nutrition so that if the P element needs are met, the plant will grow well. This study aims to determine the volume, frequency of application and interaction of bamboo root PGPR on the growth of single bud chips sugarcane seedlings. The study used a factorial Completely Randomized Design (CRD) with 15 treatments and 3 replications. The first factor is the volume of PGPR bamboo roots (K) which consists of five levels as follows: K0 = control/without PGPR, K1 = PGPR volume 5 mL/tan, K2 = PGPR volume 10 mL/tan, K3 = PGPR volume 15 mL /tan, K4 = Volume of PGPR 20 mL/tan. The second factor is the frequency of application (F) which consists of three levels as follows: F0 = 1 watering, F1 = 2 watering, F2 = 3 watering. The volume of PGPR bamboo roots as much as 15 mL/plant with a frequency of PGPR application of 2 times watering is the optimal provision for the growth of single bud chips sugarcane seedlings.

Cocoa seeds are seeds that have easy germination properties or are called recalcitrants. The technique of storing recalcitrant seeds cannot be dried below a critical moisture content, germinates easily and is not tolerant of low temperatures, so it is necessary to modify storage using sawdust storage media so that the seeds remain of good quality. The purpose of this study was to determine the effect of various doses of sawdust on the shelf life of cocoa seeds. Besides that, it also knows the best treatment of various doses of sawdust that can increase the shelf life of cocoa seeds. This study used a completely randomized design (CRD) with 6 treatments and 6 replications so that there were 36 experimental units. Parameters observed consisted of seed moisture content during storage, moldy seeds in storage and percentage of germination in seeding. Observational data were analyzed using ANOVA. If the results have a significant effect, then continue with the Duncan Multiple Range Test (DMRT) test at a level of 5%. The results showed that the best sawdust storage medium was 180 grams (A5) which could reduce the percentage of moldy seeds in storage.

The productivity of cocoa (Theobroma cacao L.) in Indonesia has decreased every year. Organic and sustainable fertilization starting from the nursery can be done as an effort to improve the productivity of cocoa. Organic fertilizers consist of 2, namely solid and liquid organic fertilizers. The use of POC can accelerate the absorption of nutrients by plant roots. POC banana peel kepok contains a number of nutrients needed by plants such as C, N, P, K, Fe, Cu, and Zn. This study aims to determine the effect and dose of differences in the volume of watering POC of good kepok banana peels on the growth of cocoa seedlings. This study used a non-factorial Completely Randomized Design (CRD) with 6 treatment levels and 4 replications. Each treatment consisted of 3 plant samples so that 72 samples of seeds were obtained. Parameters observed included plant height (cm), number of leaves (strands), stem diameter (mm), root length (cm), plant dry weight (g). Cocoa seedling growth data were analyzed using Analysis of Variances (ANOVA). If the results of the analysis have a significant effect, it will be continued with Duncan's Multiple Range Test (DMRT) at a level of 5% and data processing using the SAS application version 9.0. Based on the results of the follow-up test (DMRT), the best watering of POC banana peels on the growth of cocoa seedlings (Theobroma cacao L.) was at the volume of watering POC 120 mL.

ABSTRACT Coffee (Coffea sp.) is one type of plantation plant that has been cultivated for a long time and has a fairly high economic value. This study aims to determine the effect of chicken egg shell flour on Robusta coffee seeds on peat media. Egg shell contains 97% calcium carbonate, the rest is phosphorus, magnesium, sodium and potassium. This study aims to determine the effect of giving chicken eggshell flour on the growth of coffee seedlings on peat media. This research was conducted from September to December 2021 at the Ketapang State Polytechnic. This research was conducted using a completely randomized design (CRD) consisting of 5 treatments. The treatments were K0: without chicken egg shell flour, K1: 6.25 gr/plant, K2: 10.0 gr/plant, K3: 13, 75 gr/Plant, K4: 17.50 gr/Plant. Each treatment was repeated 6 times, each replication consisted of 3 plant samples until there were 90 experimental units. The data that has been obtained were analyzed using Analysis Of Variance (ANOVA). Data that has a significant effect, then continued with the Duncan Multiple Range Test (DMRT) at a level of 5%. The provision of chicken eggshell flour had a significant effect on the growth of plant height, number of leaves, stem diameter, root length and dry weight of robusta coffee plants, chicken eggshell flour at a dose of 17.50 g/plant was the best dose that affected the vegetative growth of coffee plants at this parameter. plant height, stem diameter, number of leaves, root length and dry weight of robusta coffee plants.

Oil palm empty fruit bunch (TKKS) biochar has the potential to increase the availability of nutrients needed by plants, namely N, P, K, Ca and Mg, which aims to increase growth on pepper cuttings (Piper nigrum L) with subsoil ultisol as a medium. This study aims to determine the best composition of oil palm empty fruit bunch biochar for the growth of pepper cuttings. This research has been carried out from May to August 2022 on Jl. Brigjem Katamso No.02, Sukaharja, Delta Pawan District, Ketapang Regency, West Kalimantan. This study used a non-factorial Completely Randomized Design (CRD) with 5 treatments and 4 replications. Each treatment consisted of 3 plants so that 60 experimental units were obtained. Parameters observed included shoot height (cm), number of leaves (strands), shoot diameter (cm), shoot dry weight (grams), and root dry weight (grams). Based on analysis of variance, it was shown that giving biochar of oil palm empty fruit bunches with a composition of 15% biochar of oil palm empty bunches (150 g) + 80% ultisol subsoil (850 g) on the growth of pepper cuttings had a significant effect on the parameters of plant height, number of leaves, diameter shoots, root volume, soil pH, and plant dry weight.
