Abundant fish catches become leftover fish or discarded fish due to various reasons, for example the fishermen's limited knowledge and facilities in fish processing methods. It turns out that the remaining fish or discarded fish can still be used. Nowadays snakehead fish (Channa striata) is widely used to make fish sauce, but in the manufacturing process only the flesh is used, this causes the skin and bones to become unusable waste. In general, fish waste contains many nutrients, namely N (Nitrogen), P (Phosphorus) and K (Potassium), which are components of organic fertilizer.</em><em>The increase in waste production greatly influences global warming which triggers climate change. With proper processing in accordance with the environment and its presence in the environment, it is hoped that the environment will be clean, healthy and comfortable, in addition, appropriate waste can produce use value that will add income. </em><em>From the research results, it can be concluded that the addition of the bromelain enzyme with a concentration of 150 mL produces the highest nitrogen content, namely 0.39%, while for the phosphorus content, the addition of 150 mL of enzyme shows a higher value, namely 0.168% and the highest nitrogen content, namely 0.037%, is owned by POC with the addition of 150 mL of bromelain enzyme.</em></p> Cindytia Prastari Roy Ibrahim Alhaviz Alhaviz Copyright (c) 2024 JURAGAN - Jurnal Agroteknologi 2024-08-13 2024-08-13 2 2 44 48 10.58794/juragan.v2i2.964 https://rumahjurnal.or.id/index.php/juragan/article/view/846 <table> <tbody> <tr> <td> <p><em>One of the reasons for the low eggplant production in Riau is that the soil type in Riau is generally Red Yellow Podzolik (PMK). Utilization of PMK soil as a medium for plant growth is faced with various problems, especially the physical, chemical and biological properties of the soil which are less </em><em>supportive for growth. To be able to improve PMK soil, it is necessary to provide a lot of organic matter, such as vermicompost fertilizer. Vermicompost organic fertilizer is an organic fertilizer plus, because it contains macro and micro nutrients and growth hormones that are readily absorbed by plants. In addition, giving egg shells is a household waste that can still be used to fertilize plants. Eggshell contains 94% calcium carbonate, 1% calcium phosphate, 1% magnesium carbonate and 4% organic compounds (Rahmawati and Nisa, 2015). The high calcium carbonate contained in eggshells can be used as an alternative source of calcium. The purpose of this study was to determine the effect and the best combination of casting and chicken eggshell fertilizer on the growth and production of pondoh round eggplant (Solanum melongena L.). This research was carried out experimentally using a factorial Completely Randomized Design (CRD), which consisted of two factors, namely K (Kascing Fertilizer) consisting of 3 levels, and factor C (Chicken egg shells), consisting of 3 levels, each consisting of 3 repetitions, The number of experimental units is 27 plots, each plot consists of 4 plants and 2 plants as samples, so that the total plant is 27 x 4 = 108 plants. The result of this research is that the interaction of vermicompost fertilizer and chicken egg shells has a significant effect on plant height, stem diameter, number of fruits, fruit weight per plant, fruit diameter of eggplant plants, by giving 100 g of castor fertilizer/plant and 30 chicken egg shells. g/plant is the best dose in this study. </em></p> </td> </tr> </tbody> </table> Paulus Diego Sinaga Neng Susi Seprita Lidar Copyright (c) 2024 JURAGAN - Jurnal Agroteknologi 2024-08-13 2024-08-13 2 2 34 43 10.58794/juragan.v2i2.846
