Abstract

Water chestnut (Eleocharis dulcis) is an underutilized plant by the people of South Kalimantan so its existence is abundant. Water chestnut has the potential as the raw material of activated charcoal to improve peat water quality which is still low. Activation is one of the processes of making activated charcoal which aims to enlarge the pores of the charcoal by oxidizing surface molecules or breaking hydrocarbon bonds. This research aims to determine whether water chestnut-activated charcoal can be used as a peat water biofilter, to determine whether H3PO4, ZnCl2, and KOH can be used as activators of water chestnut activated charcoal, and to determine which type of activated charcoal activator is most effective in purifying peat water. The activators used in this study include H3PO4, ZnCl2, and KOH with a 20% concentration. The making of activated charcoal includes reducing the size of the material, drying, carbonization, activation, activated charcoal washing, and drying. Activated charcoal of water chestnut then used in the peat water filtration process. The results showed that activated charcoal of water chestnut can be used as a peat water biofilter. H3PO4, ZnCl2, and KOH can be used as activators of water chestnut activators. The most effective activator in purifying peat water is 20% of H3PO4.

Abstract

The purpose of this study was to determine the effect of water lily activated charcoal as a biofilter in tofu wastewater treatment and to determine the effective dose of water lily activated charcoal as a biofilter in tofu wastewater treatment. The results showed that water lily activated charcoal can be used to improve the quality of tofu liquid waste; thus, it can improve the quality of tofu liquid waste which can be seen from the parameters of TSS (Total Suspended Solid). The treatment dose of 2 g of activated charcoal (A3) is the best dose to improve the quality of tofu liquid waste and has complied with the 2014 LH regulation concerning the quality standards of wastewater for the tofu industry, namely the parameters of TSS. The existence of this research can be a reference for further similar research by utilizing organic matter as an alternative in tofu wastewater treatment.

Abstract

Organic fertilizers can be in solid or liquid form, most organic fertilizers are in solid form such as manure and compost. The dragon grass (Potamogeton Sp) is one of the organic components that can be used to make bokashi fertilizer.This plant is a plant that lives in water, has a creeping rhizome and leafy branches, the leaf blades can float or submerge, and the stems are often joined. This plant does not have stomata on the leaves. The genus is generally divided into two groups, namely broadleaf and linear leaf. According to the results of the Balitra content test (2019), the dragon grass plant contains N = 3.36%, P = 0.41, K = 3.10. The purpose of this study is to see how providing dragon grass bokashi (Potamogeton sp) affects mustard greens development and yield (Brassica juncea L.).  The study took place at the Banjarbaru agro-ecotechnology experimental garden(hortibun), Banjarbaru, South Kalimantan from January until  March 2021.  This research utilised a factorial Randomized Block Design (RAK) with two factors: K0: without giving bokashi fertilizer (Control); K1: 10 tons/ha equals 19.37 g (Bokashi Dragon Grass); K2: 15 Tons/ha = 29.06 g Bokashi Dragon Grass; K3: 20 Tons/ha = 38.75 g Bokashi Dragon Grass; K4: 25 Tons/ha = 48.44 g Bokashi Dragon Grass (Bokashi Dragon Grass).To produce 20 experimental units, each experiment was repeated 4 times.

Abstract

Dragon grass (Potamogeton sp) is an aquatic plant found in the waters. In irrigation waters the presence of dragon grass is very disturbing to the irrigation manager because it reduces the water discharge along the irrigation route. This plant contains N = 3.36%, P = 0.41%, and K = 3.10% so that it has the potential to be processed into compost. Dragon grass can be used as compost using a decomposer, one of which is Trichoderma or commonly known as Trikokompost. This study aims to determine the quality of compost from dragon grass (Potamogeton sp) using three kinds of trichoderma isolates as decomposers and to determine which types of trichoderma are effective as decomposers. This research was carried out in the Greenhouse of the Department of Agroecotechnology and the Laboratory of Soil Physics and Chemistry, Faculty of Agriculture, Lambung Mangkurat University Banjarbaru from September - November 2020. The study used a completely randomized design (CRD). namely the administration of trichoderma decomposers consisting of 5 treatments which were repeated 4 times, so that 20 experimental units were obtained. Observation parameters in the study were C/N ratio, pH, temperature, humidity, macro and micro nutrients. The results showed that the type of trichoderma which is effective as a decomposer in making compost from dragon grass is Trichoderma harzianum. All parameters of macro and micro nutrients in dragon grass compost (Potamogeton sp) have met the criteria of SNI 19-7030-2004.

Abstract

Purun rats are aquatic plants that grow fast and are able to adapt so that they become a problem in swamp waters due to population explosion. One form of utilization of this plant is to process it into bokashi which is useful  for adding nutrients in the soil as organic fertilizer. Bokashi is a fermented organic fertilizer. The process of making bokashi requires a decomposer, one of which is commonly used is EM-4. Along with the times and technology, many other types of commercial decomposers contain various microorganism that can break down organic matter, including M21 Decomposer and Biodex. This study aims to determine which types of decomposer is most effective in making bokashi from rat purun and whether the results of the decomposition of several types of decomposers in making bokashi from rat purun can meet SNI. This research was carried out in August 2021-October 2021 at the Seedling House of the Department of Agroecotechnology, Faculty of Agriculture, Lambung Mangkurat University. The results of this study ware analyzed descriptively by comparing with SNI 19-7030-2004. The treatment used in this study was D1=M21 Decomposer 13,95 g, D2=EM-4 28,92 g, and D3=Biodex 50 g. The results showed that the most effective treatment in making bokashi from purun mice was D3=Biodex 50 g, which could be seen from  the decrease in the C/N rasio to 10,26%, whicht was lower than treaments D1 and D2. Based on the results of the comparison with SNI 19-7030-2004 bokashi treatment D1, D2, and D3 with parameters of temperature, color, texture, odor, moisture content and chemical content in the form of N-total, C-Organic, P-total, rasio C/N, K-total, Ca-total, Mg-total, and Fe-total can meet SNI except for pH parameters.

Abstract

Rice production produces straw which has the potential to become waste which is not utilized properly. The presence of macro and micro nutrient content in rice straw waste has potential to be used as the main ingredient for making bokashi. Bokashi fertilizer is useful for consume green spinach because they are not very familiar with red spinach. Red spinach leaves contain high nutrients including carbohydrates, protein, fat, minerals, magnesium, iron, manganese, potassium, calcium and vitamins. The provision of rice straw bokashi is expected to increase the growth of red spinach plants. The purpose of this study is determine the effect of rice straw bokashi and an effective dose to increase the growth and yield of red spinach. Research techniques used in this study was a 1-factor randomized block design (RBD), namely the dose of rice straw bokashi consisting of 5 treatments with four repetitions, so that there were 20 experimental units. The traetment in this study is J0 = without giving rice straw bokashi, J1 = NPK (40 grams/bed), J2 = 4 tonnes/ha of rice straw bokashi (1.6 kg/bed), J3 = 5 tonnes/ha of rice straw bokashi (2 kg/bed), J4 = 6 tonnes/ha of rice straw bokashi (2.4 kg/bed). The results showed that the application of rice straw waste bokashi fertilizer affect the growth and yield of red spinach as indicated by the parameters of plant height, number of leaves, leaf area and wet weight with an effective dose found in treatment J4 = 6 tonnes/ha (2,4 kg/bed).
