Abstract

Pemberian nutrisi pada budidaya secara hidroponik diberikan sesuai dengan kebutuhan tanaman. Pada proses budidaya hidroponik, nutrisi yang terkandung dalam media tanam hidroponik akan berkurang dikarenakan penyerapan tanaman maupun transpirasi. Namun, petani tidak memiliki informasi mengenai jumlah nutrisi yang hilang. Akibatnya penambahan nutrisi diberikan pada takaran seperti pada awalnya saja. pemberian nutrisi dengan cara tersebut tidak efisien, karena banyak nutrisi yang terbuang. Maka dari itu informasi mengenai jumlah nutrisi pada media tanam hidroponik sangat penting untuk diketahui. Karena itu, diperlukan sebuah instrumen yang mampu mengukur kandungan nutrisi pada media tanam hidroponik secara akurat. Fuzzy logic merupakan metode yang mampu meyelesaikan suatu masalah nonlinier yang sangat kompleks. Penerapan fuzzy logic pada alat ukur mampu menghasilkan alat ukur yang akurat. Penelitian ini bertujuan untuk menghasilkan alat ukur yang dapat mengukur kandungan nutrisi pada media tanam hidroponik dengan menggunakan sistem fuzzy logic. Dari penelitian ini, dihasilkan alat ukur kandungan nutrisi pada media tanam hidroponik dengan total error sebesar 0,506 % .

Abstract

In South Sulawesi's Takalar Regency, the Jeneberang River serves as irrigation water for neighboring areas. Several parameters, including electrical conductivity, pH, toxicity, soluble sodium, Sodium Adsorption Ratio (SAR), PI, MH, and Kelly's Ratio, were used to examine the development of water quality. The observation was conducted over three months in 2021: June (5 points), July (5 points), and August (5 points). The method for conducting physiochemical analyses was based on FAO and WHO guidelines. The study results suggest that the research locations' electrical conductivity meets the irrigation water quality standards. The nitrite concentration at the study locations ranged from 0.04 to 10.88 mg/L; thus, it was acceptable and below the standard limit level. The values of calcium and magnesium were 2.54-10.3 and 0.03 mg/L, respectively. The sodium concentration ranged between 4 and 7 mg/L. In addition, the potassium concentration in this study's water samples varied between 0.03 and 0.19 mg/L. Meanwhile, the SAR values range from 0.03 to 0.34 meq/L and are categorized as an excellent class. According Soluble Sodium Percentage standart water sample are categorized as excellent to eligible. KR, PI, and MH also indicate water sample in the suitable conditon for agricultural uses. The lead concentration at all sites was constant, 0.027 mg/L. It also happens for cadmium measurements, which show a value always the same each month, specifically 0.001 mg/L. Eventually, the analysis of cations and anions indicates that the type of water is magnesium bicarbonate. In addition, based on Kelly's Ratio data, the Jeneberang River is suitable for agricultural irrigation.
