Abstract

One local alternative that is available is the use of natural coagulants from the Moringa oleifera L. seed starch plant. Moringa seeds have antimicrobial properties that can reduce substances that should not be present in clean water so that they can purify water for clean water needs. However, the distinctive aroma of moringa is still felt, so it needs to be filtered using coconut shell charcoal and fibers . Research objectives: to determine the characteristics of domestic wastewater (pH, TSS, BOD, oil and fat) and after adding Moringa seeds as a coagulant and coconut shell charcoal and fibers as a filter media . This research was conducted in Nunleu Village-Kupang City and the NTT Provincial Health Laboratory. The method used is experiment and laboratory analysis . Phase I samples were analyzed in the laboratory to determine the characteristics of the initial water. Phase II of water purification experiments with treatment A: coagulant 150 mg / l + 10 cm thick activated charcoal + 10 cm palm thickness. Treatment B: coagulant 150 mg / l + fiber thickness 10 cm + activated charcoal thickness 10 cm. The results showed that the treatments (A and B) could reduce pH, BOD, TSS as well as oil and fat. The pH parameter has decreased tends to be acidic. TSS increased by 58.8% in Treatment (A) , but in treatment (B) there was a decrease of 15%, the TSS content still exceeds the quality standard for domestic waste set by the 2016 Ministerial Regulation, 30 mg/L.The BOD content decreased by 45.2% in treatment A while in treatment B there was a decrease of 58.3% . Furthermore, the oil and fat content was quite low, namely in treatment A there was a decrease of 45.2% while in treatment B there was a decrease of 58.3%.

Abstract

Lamtoro is a dry land plant that is widely found in East Nusa Tenggara. The abundant availability of this plant causes this plant to be of no economic value. On the other hand, this plant contains a lot of nitrogen which can be used to supply nutrients for plants, by utilizing the leaf extract.Lamtoro leaf extract can be used as organic fertilizer for chili plants, where this plant has economic value and is in great demand by the public. This study aimed to determine the effect of various concentrations of lamtoro leaf extract which showed the best results on cayenne pepper. This research has been carried out on farmers' land located in the Liliba Family, Oebobo District, Kupang City which took place from April 2020 to July 2020. The design used in this study was a randomized block design (RAK) with 5 treatments and 4 replications, with treatment P0 (control), P1 (administration of 200 ccliter of lamtoro extract concentration of water-1), P2 (administration of 250 ccliter of water-1 extract of Lamtoro concentration). ), P3 (Giving Concentration of Lamtoro Extract 300 ccliter water-1), P4 (Giving Concentration of Lamtoro Extract 350 ccliter water-1). The results of this study indicate that the treatment of lamtoro leaf extract has a very significant effect on plant height(111cm), number of leaves (221.25 pieces), number of fruit (175.25 pieces), and fruit weight (128,875 kg).

Abstract

Cucumber (Cucumis sativus L.) has a fairly good nutritional content and is in great demand by the public. Cucumber production in NTT continues to increase, but it is still low when compared to national production data. One of the efforts made is to use liquid organic fertilizers that are cheap and easy to get around us because they come from natural ingredients, namely plant residues or animal remains. Lamtoro leaf extract (Leucaena leucocephala, Ssp) is an organic fertilizer made from plants that is environmentally friendly. In addition to the fertilization factor, pruning activities are also needed to increase the weight of cucumber production. Pruning is a common cultivation action to limit excessive vegetative growth in plants so that nutrients or nutrients can be absorbed by the parts of plants that need them optimally. These nutrients can be provided by lamtoro leaf extract, then pruning is also carried out in order to reduce photosynthetic competition in order to increase cucumber production. Based on this description, it is felt that it is necessary to conduct research on the effect of giving concentration of lamptoro leaf extract and pruning on cucumber plant production. The purpose of this study was to determine the interaction of giving lamptoro leaf extract concentration and pruning on cucumber plant yields. This research was conducted from May to June 2022. This study was arranged using a randomized block design (RBD) in a factorial pattern with two factors. The first factor was the application of lamtoro leaf extract fertilizer consisting of four levels, namely: L0: control (without lamtoro leaf extract), L1: 400 cc of lamtoro leaf extract liter of water-1 plot-1, L2: 450 cc of lamtoro leaf extract liter of water-1 plot-1, L3: 500 cc of lamtoro leaf extract liter of water-1 plot-1. The second factor is pruning (P) consisting of three treatment levels, namely: P0: No pruning, P1: Pruning one leaf and one branch on segments 6–12, P2: Pruning two leaves and two branches on segments 6–12. The results obtained: administration of 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on segments 6–12 of cucumber plants had a very significant effect on cucumber plant yields, concentration of 500 cc of lamtor leaf extract lamtoro liter of water-1 plot-1 and pruning two leaves and two branches on 6–12 plant nodes produced the best growth and yield of cucumber plants, the interaction between lamtor leaf extract and pruning resulted in plant length 79.33, fruit weight 284.83 g, fruit length 30 cm and fruit diameter of 4.48 cm. Recommendation: for cucumber cultivation, it is better to use POC of lamtor leaf extract 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on internodes 6-12 plants. There needs to be further research on the use of POC concentrations of lamtoro leaf extract with higher concentrations to reduce the use of inorganic fertilizers.

Abstract

Radish plants as a food ingredient, almost all parts of the plant can be eaten raw as fresh vegetables or cooked as vegetables. The community's need for radish continues to increase as indicated by an increase in the amount of production. In 2018 radish production was recorded at 32,381 tons, in 2019 production decreased to 27,279 tons, while in 2020 production increased again to 39,048 tons. The solution in increasing radish production is by fertilizing using organic and inorganic fertilizers. The aim is to determine the interaction between SP-36 and bokasih on radish crop yields. The plan utilized was a randomized block plan (RBD) in a factorial example with two variables. The outcomes acquired: The treatment of bokashi and SP36 composts meaningfully affected plant level, number of leaves, tuber length, tuber distance across and tuber weight of radish plants. The connection between the utilization of Bokashi and SP36 composts gave the best outcomes on the normal plant level, number of leaves, tuber measurement and tuber weight of radish plants.
