Abstract

Pertanian jagung hibrida kuning di Desa Tolada, Kabupaten Luwu Utara, merupakan salah satu sektor penting yang mendukung ekonomi lokal. Namun, berbagai tantangan yang dihadapi petani dalam pengelolaan pertanian seringkali menghambat produktivitas dan efisiensi. Tujuan penelitian ini adalah merancang sebuah sistem untuk memfasilitasi pengumpulan, pengelolaan, dan penyajian data kebutuhan petani. Metode penelitian yang digunakan adalah Research and Development (R&D), yang melibatkan beberapa tahap utama. Pertama, dilakukan analisis kebutuhan untuk mengidentifikasi kebutuhan petani jagung hibrida kuning melalui wawancara dan observasi. Selanjutnya, perancangan sistem dilakukan untuk membuat desain arsitektur aplikasi berbasis Android. Setelah itu, pengembangan sistem dilakukan dengan mengimplementasikan desain menjadi aplikasi nyata. Tahap berikutnya adalah pengujian sistem untuk memastikan semua fitur berfungsi dengan baik, diikuti oleh evaluasi dan penyempurnaan berdasarkan umpan balik pengguna. Hasil dari penelitian ini adalah adanya sistem informasi berbasis Android yang dapat mendata kebutuhan petani jagung hibrida kuning di Desa Tolada, Kabupaten Luwu Utara. Sistem informasi ini juga telah diuji menggunakan metode Blackbox Testing dan telah divalidasi oleh pakar. Sistem ini mampu meningkatkan efisiensi pengelolaan data kebutuhan petani sehingga diharapkan dapat berkontribusi positif terhadap peningkatan produktivitas pertanian jagung hibrida kuning di wilayah tersebut.

Abstract

Oil palm stem waste is an environmental problem that holds great potential as an alternative substrate for mushroom cultivation due to its high lignocellulose content. Its utilization can replace the increasingly scarce sawdust while supporting the concept of a green economy. This study aimed to formulate a cultivation medium for Ganoderma lucidum based on oil palm stem waste through fermentation optimization using EM4 and molasses, to produce an eco-friendly medium that supports mushroom growth and functional food development. The research methods included substrate characterization (C/N ratio, lignin, phenol, moisture), fermentation optimization using Response Surface Methodology (RSM) with variations of EM4 dosage (1–5%), molasses concentration (5–15%), and fermentation duration (7–21 days). The optimized fermented substrate was then formulated into Baqlog medium (75% fermented substrate, 20% rice bran, 3% agricultural lime). Growth performance of G. lucidum was tested on Baqlog medium, followed by phytochemical analysis. The results showed that the optimal fermentation condition was at 3% EM4, 10% molasses, and 14 days, reducing lignin from 28.5% to 14.8%, phenol from 1.6% to 0.45%, and improving the C/N ratio from 44.2 to 28.5. Mycelial colonization was faster (18 days) compared to the control (34 days), with higher biomass (7.2 g/baglog, increased by 36%). Phenolic content also increased from 0.7 mg/g to 2.5 mg/g. In conclusion, fermentation of oil palm stem waste produced an effective medium that accelerated colonization, increased biomass, and enriched the bioactive content of G. lucidum.
