Abstract

Liquid Organic Fertilizer (LOF) is one type of fertilizer that is currently an alternative fertilizer that is widely used by the community. The purpose of this study was to evaluate the quality of liquid organic fertilizers made from the fermentation of the basic ingredients of the Mimosa pudica Linn. Using several types of bio activators.The study used a two-factorial completely randomized design (CRD). The treatment factors were the type of liquid fertilizer organic matter (A) and the microbial starter (B), there were 6 treatment combinations and was repeated 4 times with a three-day variable observed pH, temperature, color, and aroma descriptive organoleptic test. After becoming LOF, the content of N, P, K, C-Organic, Fe, and Pb were analyzed. The results of the analysis showed that the temperature and pH of the finished liquid fertilizer reached 29-31 ° C with a pH of 4. The K content in the liquid fertilizer was higher when using a mixture of canopy and root of the daughter of shame. The C-Organic content in liquid fertilizers is relatively the same. The color and aroma quality of all treatments were the same as well as the P. content. Fe and Pb content were classified as very low as required in liquid fertilizer products. Keywords: shy daughter Plants, Bio activators, Fermentation, LOF.

Abstract

Penelitian ini bertujuan untuk mengetahui proses pembuatan kapur dari cangkang siput menara (Turitella bacillum) dengan metode kalsinasi serta melakukan karakterisasi kalsium (Ca) dengan menggunakan spektrofotometri UV-Vis.Pembuatan kapur dari cangkang siput menara (Turitella bacillum) dengan metode kalsinasi menggunakan tanur dilakukan dengan perlakuan suhu 700°C, 800°C, 900°C dengan waktu 3 jam, 5 jam, 7 jam. Kapur yang dihasilkan dari proses kalsinasi dilakukan dengan menggunakan alat spektrofotometer UV-Vis.Hasil analisis kapur dari cangkang siput menara menggunakan spektrofotometer UV-Vis menghasilkan kurva standar y = 0,0465x + 0,1073 dengan r2 = 0,9851 diperoleh hasil kadar kalsium rata-rata pada kapur cangkang siput menara dengan suhu kalsinasi 700oC selama 3 jam, 5 jam dan 7 jam = 0,043 ppm, 4,026 ppm, 6,176 ppm; suhu kalsinasi 800oC selama 3 jam, 5 jam dan 7 jam = 0,531 ppm, 4,402 ppm, 6,983 ppm; suhu kalsinasi 900oC selama 3 jam, 5 jam dan 7 jam = 0,854 ppm, 4,66 ppm, 6,983 ppm.    Kata kunci: Cangkang Siput Menara (Turritella bacillum), Kalsinasi,CaO.
