Abstract

Pestisida nabati adalah pestisida yang biasanya bahan-bahannya berasal dari tumbuhan liar atau dari bagian tumbuhan seperti daun, akar, batang dan buah. Bahan-bahan ini diolah dalam berbagai bentuk seperti bentuk tepung, ekstrak atau resin yang merupakan hasil pengambilan cairan metabolisme sekunder dari bagian tumbuhan yang digunakan sebagai pestisida. Penelitian ini merumuskan permasalahan yakni Bagaimana pengaruh kombinasi pestisida nabati terhadap mortalitas ulat grayak secara in vitro dan bagaimana pengaruh kombinasi pestisida nabati terhadap aktivitas makan ulat grayak secara in vitro. Percobaan pengaruh kombinasi pestisida nabati terhadap mortalitas ulat grayak secara in vitro ini merupakan percobaan yang menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan kombinasi pestisida nabati dimana setiap perlakuan diulang sebanyak 4 kali, Sehingga percobaan ini terdiri dari 24 unit perlakuan. Hasil yang diperoleh pada kombinasi pestisida nabati dengan konsentrasi P2 sebesar 1 ml dan P5 (8 ml) menunjukkan hasil yang lebih baik dari perlakuan kombinasi pestisida nabati lainnya. Kombinasi pestisida nabati dengan beberapa perlakuan efektif dalam menurunkan aktivitas makan ulat grayak secara nyata. Sedangkan kombinasi pestisida nabati dengan konsentrasi P4 (4 ml) menunjukkan hasil yang baik dari perlakuan kombinasi pestisida nabati lainnya.

Abstract

This study aimed to determine the effectiveness of residual snow pea growing media combined with manure and mycorrhizae on the growth of bok choy without additional fertilization, supporting sustainable agriculture.The research method used was a completely randomized design (CRD) with 7 treatments and 3 replications. The treatments were as follows: P0 = 100% soil, A1D1 = 4 kg soil + 1 kg cow manure + 15 grams of mycorrhizal fertilizer. A1D2 = 3 kg soil + 2 kg cow manure + 10 grams of mycorrhizal fertilizer. A1D3 = 2 kg soil + 3 kg cow manure + 5 grams of mycorrhizal fertilizer. A2D3 = 4 kg soil + 1 kg goat manure + 15 grams of mycorrhizal fertilizer. A2D2 = 3 kg soil + 2 kg goat manure + 10 grams of mycorrhizal fertilizer. A2D3 = 2 kg soil + 3 kg cow manure + 5 grams of mycorrhizal fertilizer. Observed parameters included plant height, leaf number, fresh weight, and mycorrhizal spore density.The results showed that the combination of 1 kg of goat manure and 15 grams of mycorrhizal fertilizer (A2D1) with residual pea growing media resulted in the best growth for bok choy. In the A2D1 treatment, plant height reached 23.6 cm, with 12 leaves, and a fresh weight of 154.3 grams per plant. Meanwhile, the control treatment (P0) and the 154.3 grams of residual pea growing media alone produced the lowest growth rates.

Abstract

This study investigated the optimal use of wood species and molasses in cultivating Pleurotus ostreatus, commonly known as oyster mushroom. Previous studies have often neglected the specific impact of different wood media on mushroom yield, leading to inconsistent results in productivity. This study addresses these shortcomings by systematically evaluating the effects of wood species, including sengon, kapok, and teak, and adding molasses as a nutrient source. The methodology involved controlled experiments to assess growth parameters, including the duration of mycelial spread and the total number of fruiting bodies produced. The novelty of this study lies in the comprehensive approach of combining wood species selection with nutrient supplementation, which has not been extensively explored in previous studies. The results showed that sengon wood significantly increased fruiting body yield compared to kapok and teak, with an average of 12 fruiting bodies per bunch. This study not only provides insights into effective mushroom cultivation practices but also highlights the potential for increased productivity through strategic media selection and nutrient addition. Future benefits of this study include improved agricultural practices for mushroom farmers, leading to higher yields and better economic returns. These findings can serve as a basis for further studies aimed at optimizing mushroom cultivation techniques, ultimately contributing to sustainable agricultural development.
