Abstract

Planting sengon plants requires high-quality seeds that have high germination and vigor. Sengon seeds have a period of dormancy caused by hard seed coats. Breaking dormancy of sengon seeds needs to be done by soaking in hot water as a pretreatment so that the seed coat is softer and more permeable. The purpose of this study was to analyze the effect of water temperature and immersion time on growth potential, germination capacity, and vigor index of sengon buto seeds and the effectiveness of water temperature and immersion time on growth of sengon buto seeds. Treatment A3 with 24-hour immersion (B2A3) is the best combination for the three parameters with each value of 80% growth potential, 88.33% germination, and 71.67% vigor index. The results showed that water temperature and soaking time had an effect on the germination response of sengon buto seeds. The most effective water temperature for sengon buto seeds in this study was 100˚C with a soaking time of 24 hoursPenanaman tanaman sengon memerlukan benih yang bermutu tinggi dan memilikii daya berkecambah dan vigor yang tinggi. benih sengon memiliki masa dormansi yang diakibatkan oleh kulit benih keras. Pematahan dormansi benih sengon perlu dilakukan dengan perendaman menggunakan air panas sebagai perlakuan pendahuluan sehingga kulit benih lebih lunak dan permeable. Tujuan dari penelitian ini untuk menganalisis pengaruh suhu air dan lama perendaman terhadap Potensi Tumbuh, Daya Berkecambah, dan Indeks Vigor benih sengon buto dan efektifitas suhu air dan lama perendaman terhadap pertumbuhan benih sengon buto. Perlakuan A3 dengan perendaman 24 jam (B2A3) merupakan kombinasi terbaik untuk ketiga parameter dengan masing-masing nilai potensi tumbuh 80%, daya perkecambahan 88.33%, dan indeks vigor 71.67%. Hasil penelitian menunjukkan bahwa suhu air dan lama perendaman memiliki pengaruh terhadap respon perkecambahan biji sengon buto.

Abstract

The formation of soil properties is strongly influenced by the land physiography and land cover. The purpose of this study was to analyze the effect of land physiography (slope class) with slope classes 0-8%, 8-155, 15-25%, 25-45% and> 45% and land cover for the depth of soil solum and effective depth of roots. This research was carried out by the method: determining the slope class into five slope classes and land cover into two clusters of land cover. the design used was a factorial experiment with a slope factor A class divided into five levels and factor B land cover into two levels with replications twice. Data analysis using variance analysis (ANOVA). The results showed that land cover showed a variety of types of land cover vegetation, in vegetation areas shrubs were dominated by weeds while in the old scrub land dominated by tapus and rubber species, the amount of land cover significantly (P <0.005) in the depth of soil solum, the solum was shallower in steep slopes and little vegetation, vegetation cover (factor A) is the main factor the depth of the root is able to penetrate the soil because it depends on the land cover above, on vegetated land the bush's effective root depth is lower than the old scrub land (P <0.005) because the land cover above is dominated by thatch which has few roots and is unable to penetrate deeper into the soil layer, the percent size of the root depends on the rock percent, the less roots penetrate the soil (P <0.005) due to mechanical obstacles, and the large the small soil pH is influenced by organic matter and kel slime (P <0.005), the more organic matter the pH will decrease and the slower the slope it will cause the acidity of the soil to increase due to soil washing.
