Indonesia is an agrarian country whose economy is largely dependent on the agricultural and plantation sectors, which are also the source of Indonesia’s food security. As can be seen in the eastern of Central Java, Karangpandan is one of the villages where most of the residents work in the agricultural sector by growing crops to fulfill their daily needs. Such as chilies, cucumbers, tomatoes, eggplants and various other green vegetables.
Besides being supported by the geographical location of Karangpandang which is very suitable for the agricultural and plantation sectors, increasing production is done by using fertilizers, either organic fertilizers or chemical fertilizers. However, the use of fertilizers does not always provide effective results on plant growth. Excessive use of fertilizers can cause the soil to become no longer loose, kill microorganisms that contribute to providing nutrients in the soil, and of course pollute the surrounding waters. In addition, farmers have also been complaining about the high cost of non-subsidized fertilizers, resulting in an imbalance between the cost of maintenance and the sales price of agricultural and plantation products.
Therefore, we, the Inorganic Material Research Group, conduct community service activities with the title ” Pelatihan Pembuatan Teknologi Kombinasi Pupuk dasar dengan sistem lepas lambat (Slow release) melalui pencampuran zeolite alam Kepada mitra tani Ngudi Rejeki “.
In this research, slow-release npk fertilizer was made, by coating npk using natural zeolite.
Zeolite has properties including good porosity, high ion exchange capacity, and good selectivity, so it can be applied to the manufacture of fertilizers in agriculture. High cation exchange capacity and strong affinity for NH4+ and K+ can be used to increase the efficiency of nitrogen and potassium use.
The use of natural zeolite will control the release of fertilizers within a certain period of time according to the levels needed by plants, so that the use of fertilizers is more efficient and saves fertilizer purchase costs.
