摘要
柑橘（Citrus sp.）是生长在达乌区佩通塞乌村的主要植物。柑橘类植物产量的下降导致柑橘类植物的供应也随之减少。为了满足柑橘类植物的需求，需要增加土壤有机质。土壤有机质的影响是导致达乌区双石坞村柑橘产量下降的主要因素。因此，有必要使用 NDVI 植被密度指数估算土壤有机质，以获得充分有效的结果。此外，还进行了可靠性测试，以了解估算结果的准确程度。研究在马朗地区 Dau 区 Petungsewu 村的柑橘种植园和亚热带水果研究所进行。使用 NDVI 植被指数估算土壤有机质的准确率为 81.1%。通过配对 t 检验（t = 0.01，p = 0.991），准确度分析结果得到了加强。
ESTIMASI KANDUNGAN BAHAN ORGANIK TANAH DI LAHAN TANAMAN JERUK, KECAMATAN DAU, KABUPATEN MALANG MENGGUNAKAN INDEKS VEGETASI DAN SISTEM INFORMASI GEOGRAFIS
Citrus plants (Citrus sp.) are most plants that grow in Petungsewu Village, Dau District. The decreased productivity of citrus plants causes the availability of citrus plants also to decrease. This needs to be increased to meet citrus plants' needs. The influence of soil organic matter is the main factor causing a decrease in the productivity of citrus plants in Petungsewu Village, Dau District. Therefore, it is necessary to estimate soil organic matter using the NDVI vegetation density index to obtain adequate and efficient results. Reliability testing was also carried out to know the accuracy level of the estimates made. The research was conducted at the Citrus Plantation and Subtropical Fruit Research Institute in Petungsewu Village, Dau District, Malang Regency. Estimation of soil organic matter using the NDVI vegetation density index showed an accuracy rate of 81.1%. The results of the accuracy analysis were strengthened by the presence of a paired t-test with a value of t = 0.01 and a value of p = 0.991.
