Pakcoy is a leaf vegetable or annual plant that can only be harvested once. To get a good production of pakcoy plants, a mixture of planting media and liquid organic fertilizer of lamtoro leaves is carried out. This study aims are to determine the response of a mixture of planting media and liquid organic fertilizer of lamtoro leaves to the growth and production of pakcoy (Brassica rapa L). The parameters observed were plant height per sample, number of plant leaves per sample, plant leaf area per sample, weight of crop production per sample, weight of crop production per plot, weight of plant consumption per sample. The results showed that the response of the administration of the planting media mixture had a very significant effect on the plant production weight parameters per plot but did not significantly affect the plant height parameters per sample, number of plant leaves per sample, plant leaf area per sample, plant production weight per sample, consumption weight plants per sample. The results of research on the application of liquid organic fertilizer of lamtoro leaves did not have a significant effect on the observed parameters. Whereas the interaction between planting media and liquid organic fertilizer of lamtoro leaves gave no significant effect on all parameters observed.

Efforts to optimize the growth and productivity of shallot plants (Allium ascalonicum L) by applying organic compost of duck manure and POC of household waste. This research method used a factorial randomized block design (RBD) consisting of 2 treatment factors. The first factor was the application of duck manure organic compost (B), namely B0 = 0 g/planting hole, B1 = 50 g/planting hole, B2 = 100 g/planting hole and B3 = 150 g/planting hole. The second factor was the provision of POC for household waste (L), namely L0 = 0 ml/planting hole, L1 = 50 ml/planting hole, L2 = 100 ml/planting hole, L3 = 150 ml/planting hole. Parameters observed were the number of tillers (saplings), dry tuber weight per sample (g) and dry tuber weight per plot (g). The results showed that the application of duck manure organic compost had a very significant effect on the parameters of the number of tillers (saplings), dry production per sample (g) and dry production per plot (g). Where is the best treatment onB3 = (150 g/planting hole). PPOC distribution of household waste and their interactions had no significant effect on the parameters of the number of tillers (saplings), dry production per sample (g) and dry production per plot (g).

Efforts to improve the peanut cultivation system (Arachis hypogaea L) need to be done to increase peanut productivity in order to reduce imports. One way that can be done is by using organic materials such as POC banana hump and cow dung fertilizer. This study aims to determine the effect of giving POC banana weevil and cow dung fertilizer on the growth and production of peanuts (Arachis hypogaea L). This research was conducted at Jln. Milkfish, East Binjai District, North Sumatra by using a factorial randomized block design consisting of the first factor, namely the provision of banana weevil POC (P) consisting of 3 levels, namely P0 (0 liters/plot), P1 (1 liter/ liters of water/plot). ) and P2 (1 liter/liter of water/Plot). The results showed that the application of POC banana weeds had no significant effect on all observation parameters and cow dung had a very significant effect on wet peanut production per sample and wet peanut production per plot but had no significant effect on plant height parameters, number of leaves, number of pods. per sample and number of pods per plot. From the application of cow dung fertilizer to the production of peanut plants, the best was in K3 (3 kg/plot) and the lowest production of peanuts was in k0 (0 kg/plot).

This study aims to determine the effectiveness of using coffee grounds and horse urine POC administration on the production of radish (Raphanus sativus L.). This research method used a factorial randomized block design (RBD) consisting of 2 factors. The factors studied were coffee grounds compost (K) treatment factors consisting of 4 levels K0 = 0 kg/Plot, K1 = 1 kg/Plot, K2 = 2 kg/Plot, K3 = 3 kg/Plot and the second factor was the provision of POC Horse urine (U) consists of 4 levels, namely U0 = 0 ml/liter of water/plot, U1 = 300 ml/liter of water/plot, U2 = 600 ml/liter of water/plot, U3 = 900 ml/liter of water/plot. Parameters observed were tuber length (cm), tuber production per sample (g) and tuber production per plot (g). The results showed that the application of coffee grounds compost and horse urine POC to radish production had a very significant effect on the parameters of tuber length, tuber production weight per sample and tuber production weight per plot. Where the best treatment for coffee grounds compost was in the K3 treatment (3 kg), the best treatment for horse urine POC was in the U3 treatment (900 ml/liter of water/plot).

Pakcoy(Brassica rapa L) is an annual plant originating from the Brassica species which is easy to obtain at an economical price and contains ingredients needed by humans such as minerals, vitamins and fiber. This study aims to determine the response of water hyacinth liquid organic fertilizer and chicken manure compost planting medium with husk charcoal to the growth and production of pakcoy (B. rapa L). This research was conducted at Jalan Ikan Bandeng, Tanah Tinggi Village, East Binjai District, Binjai City using a Factorial Randomized Block Design (RBD) consisting of 2 factors, 16 combinations and 2 repetitions. The treatment of growing media (M) was 4 levels, namely: M0 = Control, M1 = 1:1 (Charcoal + Chicken Manure Compost), M2 = 2:1 (Charcoal + Chicken Manure Compost) and M3 = 1:2 (Charcoal rice husk + chicken manure compost). There are 4 levels of water hyacinth liquid organic fertilizer (P), namely: P0 = control (using plain water), P1 = 60 ml/500 liters of water/polybag, P2 = 120 ml/500 liters of water/polybag, and P3 = 180 ml /500 liters of water/poly bag. Parameters observed were plant height, number of leaves, leaf area per sample, production weight per plot, plant fresh weight per sample and net consumption weight per sample. The results of the research on planting media of chicken manure compost with rice husk charcoal had a significant effect on all observed parameters. The results of the study applying water hyacinth liquid organic fertilizer had no significant effect on the parameters of plant height, number of leaves, leaf area, net weight consumed per sample, fresh weight of plants per sample and had a significant effect on the parameter of production weight per plot.
