Abstract

Analisis korelasi dan sidik lintas merupakan analisis statistik deskriptif untuk memahami hubungan langsung dan tidak langsung antar karakter morfologi. Penelitian ini bertujuan untuk mengetahui respon perendaman benih terhadap karakter amatan; menduga aksi gen yang mengendalikan karakter perkecambahan benih padi terhadap perendaman benih; memperoleh karakter amatan yang memiliki keeratan hubungan dengan karakter lainnya melalui nilai korelasi; dan mengetahui pengaruh langsung dan tidak langsung beberapa karakter amatan perkecambahan benih padi terhadap beberapa perlakuan perendaman benih. Penelitian ini dilaksanakan di Laboratorium Agronomi Fakultas Pertanian Universitas Negeri Gorontalo pada Bulan November 2024. Penelitian ini menggunakan rancangan faktorial dua faktor dalam RAL, dimana faktor pertama terdiri atas jenis perendaman yaitu tanpa perendaman, perendaman menggunakan air biasa, air kelapa, air panas suhu 40°C, dan ekstrak bawang merah. Sedangkan untuk faktor kedua yaitu durasi perendaman yang terdiri atas 5 menit dan 10 menit. Hasil penelitian menunjukkan perendaman benih berpengaruh nyata terhadap perkecambahan benih padi Var. Inpari Nutri Zinc yang dibuktikan dari nilai kuadrat tengah, dominansi karakter amatan dipengaruhi oleh aksi gen aditif dan epistasis komplementer dan dikendalikan oleh banyak gen, karakter panjang plumula dan radikula berkorelasi positif dan sangat kuat dengan karakter kadar air kecambah. Sementara bobot kering kecambah berkorelasi negatif dan berpengaruh sangat nyata terhadap kadar air kecambah; dan karakter bobot kering kecambah menghasilkan pengaruh langsung tertinggi serta karakter panjang radikula menghasilkan pengaruh tidak langsung tertinggi. Sehingga, karakter kadar air kecambah dan panjang plumula dapat digunakan sebagai karakter seleksi untuk uji perkecambahan benih padi menggunakan perlakuan perendaman benih. Correlation and cross-fingerprint analysis is a descriptive statistical analyses to understand the direct and indirect relationships between morphological characters. This study aims to determine the response of seed soaking to observed characters; predict the action of genes that control rice seed germination characters to seed soaking; obtain observed characters that have a close relationship with other characters through correlation values; and determine the direct and indirect effects of several observed characters of rice seed germination on several seed soaking treatments. This study was conducted at the Agronomy Laboratory, Faculty of Agriculture, Gorontalo State University in November 2024. This study used a two-factor factorial design in RAL, where the first factor consisted of the type of soaking, namely, without soaking, soaking using plain water, coconut water, hot water at 40°C, and shallot extract. The second factor is the duration of soaking, which consists of 5 minutes and 10 minutes. The results showed that seed soaking had a significant effect on the germination of rice seeds of Var. Inpari Nutri Zinc, as evidenced by the mean square value, the dominance of observed characters is influenced by additive gene action and complementary epistasis, and is controlled by many genes. The plumule and radicle length characters decrease positively and very strongly with the character of the water content of the sprouts. While the dry weight of the sprouts has a negative and very significant effect on the water content of the sprouts, the dry weight character of the sprouts produces the highest direct effect, and the radicle length character produces the highest indirect effect. Thus, the characters of the water content of the sprouts and the length of the plumule can be used as selection characters for rice seed germination tests using seed soaking treatments.

Abstract

The current land suitability criteria for konjac are incomplete and fail to consider land dimensions and quality, which influence optimal yield. This research aims to develop criteria for konjac land suitability based on the dimensions, quality, and characteristics of selected land. In Gorontalo Province, Indonesia, 131 land units were surveyed to obtain data on the quality and characteristics. Selection of land dimensions, quality, and characteristics using Structural Equation Modeling (SEM) with Partial Least Squares (PLS). Meanwhile, the optimum yield and distinguished land suitability criteria for konjac plants using the boundary line method. The results indicated that intrinsic and extrinsic dimensions determined the new land suitability criteria. In the intrinsic dimension, land quality was assessed based on root conditions, oxygen availability, nutrient availability, nutrient retention, and sodicity. For the extrinsic dimension, land quality only comprised temperature, water availability, land preparation, and erosion hazard. Land characteristics in the intrinsic dimension consisted of soil drainage, texture, bulk density, particle density, porosity, pH, organic C, CEC, base saturation, total N, available P, and exchangeable K. For the extrinsic dimension, land characteristics included slope, soil erosion, surface rocks, and rock outcrops. The highest optimum yield of konjac was 9.17 t/ha, and the lowest was 6.69 t/ha, respectively.

Abstract

Maize (Zea mays L.) is a significant food commodity in Telaga Biru Subdistrict, Gorontalo Regency; therefore, information on soil fertility is crucial as a basis for effective land management. This study aims to analyze the chemical and physical fertility of soils in maize cultivation areas and to identify efforts to improve maize productivity in Telaga Biru Subdistrict. The study was conducted from April to November 2025 in Telaga Biru Subdistrict, Gorontalo Regency. A descriptive quantitative method with a land unit-based survey approach was employed. Soil sampling was conducted diagonally in three villages: Timuato, Modelidu, and Talumelito, at a depth of 0-20 cm. The analyzed chemical fertility parameters included soil pH, nitrogen, organic carbon, cation exchange capacity, available phosphorus, potassium, and base saturation. Physical soil properties analyzed included soil texture, bulk density, and soil color. The findings showed that the soil pH was slightly acidic, with nitrogen and organic carbon contents falling into the low to moderate categories. The cation exchange capacity and the availability of phosphorus and potassium were moderate, while base saturation was relatively low: The physical soil properties were dominated by clay to clay loam textures with relatively high bulk density values. These conditions indicate that maize cultivation land in Telaga Biru Subdistrict has sufficient fertility to support plant growth; however, appropriate soil management is still required through balanced fertilization, the addition of organic matter, and improvement of soil physical properties to enhance productivity sustainably.
