Abstract

The Effect of Mulch and Liquid Organic Fertilizer on Growth and Production of Red Chilli (Capsicum annuum L.) Chilli (Capsicum annuum L.) is one type of vegetable plant that has high economic value and high demand in Indonesia. Organic mulch treatment and liquid organic fertilizer are among the organic farming techniques could be used to increase the production of red chilli. The aim of the study was to find the type of organic mulch and concentration of liquid organic fertilizer Agrobost to increase the production of red chilli. The research used a randomized group with split plot design in separate plots with two treatment factors. The first factor was mulch treatment consisting of 3 levels, i.e. without mulch, husk charcoal mulch, and saw shaved mulch. The second factor was the concentration of liquid organic fertilizer with 3 levels of treatment, i.e. without giving liquid organic fertilizer, giving liquid organic fertilizer at concentration of 7.5 mL/L of water, and 15 mL/L of water. The results showed that there was no interaction between mulch treatment and liquid organic fertilizer on the growth and yield of large red chilli plants. Giving husk charcoal mulch could increase the relative water content of leaves, number of fruit formed, and suppress weed populations. Liquid organic fertilizer with a concentration of 15 mL/L of water could increase plant height, leaf chlorophyll content, and leaf relative water content.

Abstract

Spatial Analysis of the Potential and Status of Soil Damage in Sawan District, Buleleng Regency This study aims to determine the potential and distribution of soil damage status in Sawan District, Buleleng Regency. The research method used is a survey method and a qualitative method of spatial analysis. Based on the results of overlaying land use maps, slope maps, rainfall maps and soil types maps, there are 7 homogeneous land units. The land was taken from homogeneous land units of existing land use, namely natural forests, mixed gardens, settlements and rice fields. After the soil sample was taken, it was continued with soil analysis in the laboratory to determine the bulk density, total porosity, degree of water release, pH, fraction composition, electrical conductivity and number of microbes. The results showed that Sawan District had low soil damage potential at the locations of homogeneous land units I, II, III, and IV and moderate soil damage potential at homogeneous land units V, VI, and VII locations. The status of soil damage in Sawan District is lightly damaged. The parameter causing the damage status in the research area is the water release degree parameter. These parameters get a relative frequency value of 100% with a score of 4 (four). The direction of controlling the status of soil damage that can be done is by providing organic matter and good soil management efforts.

Abstract

Effect of Several Concentrations of Chrysal Solution on Vase Life of Cut Hydrangea Flowers (Hydrangea macrophylla) Hydrangea or hydrangea flowers has a unique color and shape of flower buds. However, like other horticultural products, cut flowers have a relatively short vase life (perishable). The decrease in the quality of cut flowers after postharvest is caused by the ongoing respiration process. For the quality of cut flowers to remain fresh for a relatively long time, cut flowers need to be given post-harvest handling so that the quality of cut flowers remains good, which is by using a preservative solution. In short, preservative solutions generally contain sugar, germicide, and citric acid which can help prolong vase life. This study aims to determine the effect of chrysal solution in prolonging the vase life of hydrangea flowers and to determine the best concentration of preservative solution to maintain the vase life of hydrangea flowers (Hydrangea macrophylla). The study used a single factor completely randomized design (CRD) in the form of Chrysal preservative solution with concentrations of 0 ppm (C0), 5000 ppm (C1), 7500 ppm (C2), 10000 ppm (C3), and 12500 ppm (C4). The results showed that the best concentration of Chrysal obtained was with a concentration of 10000 ppm chrysal solution with a long vase life of 11.20 days.

Abstract

Evaluation of Rice Field Fertility Status Based on Geographical Information System in Negara District, Jembrana Regency Lowland rice production at Negara District in 2014 was 6.89 tons/ha and in 2015 decreased to 6.67 tons/ha. This is thought to be due to the reduced ability of the land to support the agricultural production process. The purpose of this study was to determine the status of soil fertility and the parameters of the limiting factors of soil fertility, to make a map of the status of soil fertility, and to provide direction for the management of soil fertility. This research was conducted from December 2021 – March 2022. The methods used in this study included survey and soil test methods with parameters of fertility status including CEC; BS; organic C; total P and total K. The results showed two soil fertility statuses in the study area, namely low in HLU I (Pengembengan Village, West Tegal Badeng, East Badeng Tegal, Baluk, Banyubiru, Kaliakah, Lelateng, Bale Agung Baler) and HLU II (Pengambengan Village, East Tegal Badeng, Banyubiru, Lelateng) and moderate soil fertility in HLU III (Kaliakah Village, Berangbang, Bale Agung Baler) and HLU IV (Kaliakah Village, Berangbang, Bale Agung Village). The limiting factors for soil fertility status were CEC and moderate K2O content and low organic C content. The direction of soil fertility management is the addition of organic matter and K fertilizer to improve soil fertility status.

Abstract

Location Specific Balanced Fertilization Through Evaluation of Soil Fertility Status in Rice Field, Klungkung District, Bali Province Rice is the main commodity cultivated by farmers in Indonesia, but there are obstacles in the productivity of rice plants, one of which is fertilization. Location-specific balanced fertilization is carried out to determine the application of fertilizer according to the fertility status of paddy fields so that fertilization will be more efficient. This study aims to determine soil fertility status, spatial distribution of soil fertility status, and provide site-specific balanced fertilization recommendations for paddy fields in Klungkung Sub-district area. This research using survey methods and soil tests in the laboratory and integrated using Geographic Information System (GIS). This research was initiated by spatial analyst for mapping the Land Unit (SLH) area with overlaid the thematic maps (i.e., soil types, slope, and paddy field area). Then four land unit maps were obtained, and soil samples were taken by purposive sampling and the chemical properties of the soil were analyzed including: CEC; KB; C-organic; P-total; and K-total. The results showed that the soil at the study site had three soil fertility statuses, namely low fertility status located at SLH II (Tangkas Village) with an area of 37.53 ha and SLH III (Selat Village) with an area of 46.26 ha, medium fertility status located at SLH IV (Akah Village) with an area of 36.31 ha, while high soil fertility status is located in SLH I (Jumpai Village) with an area of 96.53 ha. Parameters of low P-total and total K content in SLH II (Tangkas Village) and SLH III (Selat Village) became a limiting factor in soil fertility status, so it was necessary to add 100 kg/ha of SP-36 fertilizer, Phonska 100 NPK fertilizer kg/ha, and the addition of KCl fertilizer as much as 100 kg/ha.

Abstract

Soaking Gerbera Cut Flowers (Gerbera jamesonii) in a Mix of Coconut Water Solution and Wuluh Starfruit Extract to Extend Vase Life Gerbera is a flowering ornamental plant that is used as cut flowers and has high economic and aesthetic value. Gerbera flowers are often damaged such as wilting, easily broken stems, broken buds and flower discoloration. The very short shelf life of cut gerbera flowers requires proper postharvest handling to maintain freshness. This research aims to determine the effect of coconut water (Cocos nucifera) and wuluh starfruit (Averrhoa bilimbi) extract and its interaction in increasing vase life and to determine the best soaking solution dose for gerbera cut flowers. The research used a Completely Randomized Design consisting of two factors, that is coconut water with doses of K1: 40 ml, K2: 60 ml, and K3: 80 ml, and wuluh starfruit extract with doses of B1: 10 ml, B2: 20 ml, and B3: 30 ml, there were 9 treatment combinations and each treatment was repeated three times. The results showed that the interaction between coconut water and wuluh starfruit extract had a significant effect on the solution acidity and vase life variables. Treatment of 80 ml coconut water + 10 ml star fruit extract (K3B1) was able to maintain the appearance of gerbera cut flowers in a vase up to 13,83 days.
