Beras merupakan bahan makanan pokok sebagian besar penduduk Indonesia dan mengalami defisit setiap tahun. Budidaya padi gogo di lahan marginal seperti Ultisol menjadi salah satu alternatif untuk memenuhi kebutuhan beras. Ultisol memiliki beberapa masalah dalam pengelolaannya seperti keasaman dan kekurangan nutrisi. Diperlukan input seperti sekam padi dan jerami padi berupa residu biochar dan asap cair untuk memperbaiki masalah. Penelitian ini bertujuan untuk mempelajari pengaruh aplikasi biochar, asap cair dan interaksi biochar dan asap cair terhadap pertumbuhan padi gogo di medium Ultisol. Penelitian ini dalam bentuk percobaan faktorial disusun dengan rancangan acak lengkap (RAL). Faktor pertama adalah residu biochar terdiri dari 4 taraf (0/tanpa biochar, 10 ton ha-1 sekam padi, 10 ton ha-1 jerami padi dan 5 ton ha-1 sekam padi + 5 ton ha-1 jerami padi). Faktor kedua adalah asap cair terdiri dari 3 taraf (0/tanpa asap cair, 0.5 ml L-1 sekam padi dan 0.5 ml L-1 jerami padi) masing-masing kombinasi diulang tiga kali. Hasil penelitian menunjukkan bahwa residu biochar sekam padi dan jerami padi masing-masing dosis 10 ton ha-1 meningkatkan tinggi tanaman, jumlah anakan maksimum, jumlah anakan produktif, umur keluar malai dan bobot kering jerami dibandingkan kontrol bahkan pada campuran keduanya (1:1) peningkatannya lebih tinggi. pemberian asap cair sekam padi dan jerami padi dosis 0.5 ml L-1 meningkatkan tinggi tanaman, jumlah anakan maksimum, jumlah anakan produktif, umur keluar malai, bobot kering jerami dibandingkan kontrol. Interaksi campuran residu biochar (sekam padi dan jerami padi) dosis 10 ton ha-1 (1:1) dan asap cair 0.5 ml L-1 (sekam padi dan jerami padi) meningkatkan tinggi tanaman, jumlah anakan maksimum, jumlah anakan produktif, umur keluar malai dan bobot kering jerami dibandingkan kontrol.

Kuantan Singingi Regency is one of the ruminant-producing districts in Riau Province. Koto Simandolak Village, located in Benai District, Kuantan Singingi Regency, the majority of the people work as farmers. Generally, farmers in Koto Simandolak Village cultivate livestock traditionally, namely by releasing them to the wild. This condition causes several problems including livestock manure, pollution of the village environment, and conflicts with residents. This problem can be solved if the farmer wants to keep the cattle. By holding cattle, the manure will be collected directly in the cage. Animal manure can be processed and used in biogas and organic fertilizer. The Research and Community Services Team of Universitas Riau saw the potential for utilizing livestock manure waste in Koto Simandolak Village. The Team conducts training and assistance in the installation of biogas reactors as well as training and mentoring in the biogas production process using livestock manure. Another output of biogas production is organic fertilizer. The ultimate goal of this service activity is to increase the income of the target community, namely through increasing livestock production, biogas production, and organic fertilizer production.

The first problem faced in cultivating oil palm is the procurement of seeds. Ultisol soil when used for breeding media has several problems such as having a wet saturation of less than 35% at a depth of 125 cm below the upper limit of the argillic horizon. Ultisol has an acidity level of less than 5.5, low to moderate organic matter and low nutrition. The addition of organic material such as the LCC Mucuna bracteata compost is highly recommended because it will improve the physical, biological, and chemical properties of the soil, so that it increases the availability of nutrients in the soil to be optimal. This study aims to determine the effect of LCC mucuna bracteata compost on ultisol soil medium and determine the dosage/dose of LCC Mucuna Bracteata compost which provides the best growth of oil palm seedlings (Elaeis guineensis Jacq). This research was carried out experimentally with a Completely Randomized Design (CRD), consisting of 5 treatments and 4 replications. The results of this study indicate that distributing doses of 400 g/8 kg of soil improved the physical and chemical properties of the soil and the vegetative growth of oil palm seeds.
