Abstract

Hama uret (Lepidiota stigma F.) merupakan ancaman serius bagi tanaman tebu. Penggunaan pestisida kimia dalam pengendalian hama uret menimbulkan masalah jangka Panjang, diantaranya pencemaran lingkungan dan resistensi hama. Alternatif untuk mengatasi masalah tersebut adalah dengan penggunaan agen hayati seperti Metarhizium sp. dan biopestisida. Tujuan penelitian ini yaitu: untuk melihat efektivitas jamur Metarhizium sp. dan biopestisida alami dari tandan kosong kelapa sawit dalam mengendalikan hama uret di lahan tebu Desa Grati, Lumajang dengan melihat mortalitas dan populalsi hama uret. Metode penelitian yang digunakan yaitu penelitian kuantitatif dengan desain penelitian Rancangan Acak Kelompok (RAK) Non-Faktorial. Terdapat tiga perlakuan yaitu aplikasi jamur Metarhizium sp, aplikasi biopestisida dan kontrol dengan masing-masing perlakuan menggunakan 10 kali ulangan. Data yang diperoleh dianalisis menggunakan ANOVA dengan uji lanjut BNT taraf 5% jika terdapat pengaruh nyata. Hasil penelitian menunjukkan bahwa jamur Metarhizium sp. lebih efektif dalam membunuh hama uret tebu (92,67%) dibandingkan biopestisida (78%).

Abstract

This study aimed to determine the imbibition rate of bean seeds (Phaseolus vulgaris L.) through soaking in distilled water (aquades) for 32 hours. The imbibition process was observed by measuring the seed weight every two hours using a digital scale. A total of 25 seeds were used for each replication, with five replications conducted. The results showed that water uptake occurred rapidly during the first 8 hours and then slowed down and showed no further imbibition activity until the 32nd hour. The data revealed a characteristic imbibition curve pattern, providing valuable insights for pre-sowing seed treatment to enhance germination efficiency. This research is important to determine how long farmers should soak seeds before planting to achieve optimal germination while preventing excessive soaking that may cause seed rot.

Abstract

Priming is a physiological technique of hydration of seed to improve metabolic processes before germination to accelerate germination and seedling growth under normal and stress conditions. This research is aimed to study the pretreatment using ultra-fine bubble (UFB) water to increase viability and vigor of seeds before planting (pre-planting) and during storage (pre-storage). This research was conducted at the Laboratory of Seed Quality Testing, IPB University, Indonesia. The research consisted of two experiments, i.e., UFB water priming to increase viability and vigor of bean seeds and its storability after priming. The first experiment was arranged using a completely randomized design with a combination of seed lot treatments (L1: initial germination percentage (GP) about 80%, L2: initial GP around 70%, and L3: initial GP around 60%) with priming (P0: no priming/control, P1: soaked in distilled water for 60 minutes, P2: distilled water for 120 minutes, P3: 8 ppm UFB water for 60 minutes, P4: 8 ppm UFB water for 120 minutes, P5: 20 ppm UFB water for 60 minutes, P6: UFB water 20 ppm for 120 minutes). The second experiment was arranged using a nested design with the main factor being the condition of the storage room and priming as the second factor nested in the main factor. The storage room condition factors consisted of KM: room conditions (temperature 28±5˚C, RH 73±7%) and AC: air-conditioned room (18±2 ̊C, RH 61±7%). The priming factor consisted of two levels, namely P0: without priming and P1: priming with 20 ppm UFB water soaked for 120 minutes. The results showed that priming treatment with UFB water 20 ppm for 120 minutes as a pre-planting treatment can increase the viability of bean seeds, particularly for seeds with low initial viability, and primed bean seeds with an initial viability of approximately 80% were able to retain their viability for 16 weeks of storage in an air-conditioned room.
