Production of white eggplant plants continues to increase from year to year, but this year (2023) production has decreased, this is because quite a few farmers have experienced crop failure. The occurrence of crop failure was caused by several obstacles, especially the decreasing fertility level of alluvial soil. To increase the production of white eggplant, farmers are trying to overcome this obstacle by fertilizing. For this reason, in cultivating white eggplant plants, alluvial land needs ameliorant which is easy to obtain and cheap, in addition to providing N, P and K fertilizer, namely by providing tankos biochar. and chicken droppings. This research will conduct an experiment on the effect of providing organic fertilizer Biochar tankos + Chicken Manure biochar on the growth and yield of white eggplant plants in Alluvial soil. The design used in this research was a Completely Randomized Design (CRD) with a treatment dose of organic fertilizer. Biochar tankos + Chicken Manure. Each treatment was repeated 3 times so that 27 experimental units were obtained. The experimental parameters taken were uptake of N, P, K from leaves and weight of white eggplant in harvest 1 and harvest 2. The conclusion drawn was that Biochar Tankos + chicken manure enriched with 75% NPK can help increase the uptake of N, P and K in plants, which increases the supply. The dose of organic fertilizer means that the availability of N, P and K in the soil will also increase. Apart from that, Biochar Tankos + chicken manure enriched with 75% NPK can help increase white eggplant production, where as the dose of organic fertilizer increases, white eggplant production will also increase. Optimum results in the second harvest were obtained in treatment B2 = Chicken Manure Biochar 40 t.ha-1 + NPK 75%, in accordance with the white eggplant yield per ha of the variety. Yasinta. B3M1 treatment with a dose of 1360 g/polyb and compound NPK fertilizer 75% of the recommended 500 g, gave white eggplant production in the first harvest of 194% and the second harvest of 27.45%. Key words: Alluvial, tankos biochar, white eggplant, chicken manure, NPK uptake INTISARIProduksi tanaman terung putih dari tahun ke tahun terus meningkat namun pada tahun ini (2023) produksinya menurun, hal ini dikarenakan tidak sedikit petani yang mengalami gagal panen. Terjadinya gagal panen diakibatkan karena adanya beberapa kendala, terutama tingkat kesuburan tanah Alluvial yang menurun. Untuk meningkatkan hasil produksi terung putihnya, para petani berusaha mengatasi kendala tersebut dengan melakukan pemupukan, untuk itu dalam budidaya tanaman terung putih, lahan Aluvial perlu amelioran yang mudah didapat dan murah harganya, selain pemberian pupuk N,P dan K, yaitu dengan pemberian biochar tankos dan kotoran ayam. Penelitian ini akan melakukan percobaan tentang pengaruh pemberian pupuk organik Biochar tankos + biochar Kotoran Ayam terhadap pertumbuhan dan hasil tanaman terung putih di tanah Alluvial. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan perlakuan dosis .pupuk organik. Biochar tankos + Kotoran Ayam. Masing-masing perlakuan diulang sebanyak 3 kali sehingga akan diperoleh 27 unit percobaan. Parameter percobaan yang diambil adalah SerapanN,P,K daun dan Berat terung putih pada panen 1 dan panen 2. Kesimpulan yang diambil adalah Biochar Tankos + kotoran ayam diperkaya NPK 75% dapat membantu meningkatkan Serapan N, P dan K tanaman, dimana semakin meningkat pemberian dosis pupuk organiknya maka ketersediaan N,P dan K tanah juga semakin meningkat, selain itu Biochar Tankos + kotoran ayam diperkaya NPK 75% dapat membantu meningkatkan produksi terung putih, dimana semakin meningkat pemberian dosis pupuk organiknya maka produksi terung putih juga semakin meningkat. Hasil optimum pada panen kedua didapat pada perlakuan B2 = Biochar Kotoran Ayam 40 t.ha-1 + NPK 75 %, sesuai dengan hasil terung putih per ha pada varietas. Yasinta. Perlakuan B3M1 dengan dosis 1360 g/polyb dan pupuk NPK Majemuk 75% dari anjuran yaitu 500 g, memberikan produksi terung putih pada panen I sebesar 194% dan panen II sebesar 27.45 %.

Alluvial land in Indonesia, especially in West Kalimantan, has potential as an agricultural area, but has obstacles that can reduce productivity. The use of organic matter such as rice straw compost and Local Microorganisms is an alternative that can be used to overcome the problem of alluvial soil. This study aims to determine the effect of rice straw compost and banana hump Local Microorganisms on the availability of N, P, K, and corn plant growth. The research was carried out on the land of Dusun Karya I, Desa Kuala Dua, Kabupaten Kubu Raya. The study used the Complete Random Design (CRD) method which consisted of 5 treatment levels including: J0 = 0 (control), J1 = 280 g/polybag (10 tons/ha), J2 = 560 g/polybag (20 tons/ha), J3 = 840 g/polybag (30 tons/ha), and J4 = 1120 g/polybag (40 tons/ha). Each treatment is repeated 5 times there are 25 polybags. The results showed that the application of rice straw compost and banana hump Local Microorganisms had a real effect on soil pH, C-organic soil, P-available soil, plant height, stem diameter, and dry weight of roots.

Cultivation of purple eggplant plants in alluvial soils has several obstacles, one of which is the lack of macro and micro nutrients, so to overcome this it is necessary to give a combination of rice straw compost and rice husk biochar to increase the availability of nutrients N, P, K and the growth of purple eggplant plants on alluvial soils. This study aims to determine the effect of a combination of rice straw compost on the availability of nutrients N, P, K and the growth of purple eggplant plants (Solanum melongena L.) in alluvial soil. This research took place from May - September 2023, conducted at the experimental land of the Faculty of Agriculture, Tanjungpura University, Pontianak City, West Kalimantan. This study used a completely randomized design (CRD) consisting of 1 factor with 6 treatments, namely: P0 = no treatment; P1 = compost 244 g/polybag; P2 = biochar 217 g/polybag; P3 = compost 183 g/polybag + biochar 54 g/polybag; P4 = compost 122 g/polybag + biochar 108 g/polybag; P5 = compost 61 g/polybag + biochar 163 g/polybag. Each treatment was repeated 4 times so there were 24 polybags. The results showed that the best dose of the combination of rice straw compost and rice husk biochar was found in the 30 ton/ha treatment (P1) which could increase N-total by 73.23%, plant height by 28.18% and stem diameter by 13.75%Key words: alluvial soil; purple eggplant; rice straw compost; rice husk biocharINTISARI Budidaya tanaman terung ungu di tanah aluvial memiliki beberapa kendala, satu diantaranya yaitu kekurangan unsur hara makro dan mikro, sehingga untuk mengatasi hal tersebut diperlukan pemberian kombinasi kompos jerami padi dan biochar sekam padi untuk meningkatkan ketersediaan hara NPK serta pertumbuhan tanaman terung ungu pada tanah aluvial.

This research aims to determine the nutrient uptake of N, P and K from purple eggplant plants in alluvial soil. This research will take place from July – September 2023, carried out at the experimental field of the Faculty of Agriculture, Tanjungpura University, Pontianak City, West Kalimantan. This research used a Completely Randomized Design (CRD) with 6 treatments, namely: P0 = 0 (control); P1 = 100% rice straw; P2 = 100 rice husk biochar; and P3 = 75% rice straw compost + 25% rice husk biochar; P4 = 25% rice straw compost + 75% rice husk biochar; P5 = 50% rice straw compost + 50% rice husk biochar. Each treatment was repeated 4 times so there were 24 polybags. The variables observed in this study were the dry weight of the top of the plant, the uptake of N, P and K, the number of fruit per plant, the weight of the fruit per plant and the weight of the fruit per plant. The results of this study showed that the combination of rice straw compost and rice husk biochar had no significant effect on N, P and K uptake.
