[GROWTH AND LETTUCE YIELD (Lactuca sativa L.) BY GIVING MANURE AND RICE HUSK ASH IN INCEPTISOL]. Increasing market demand for lettuce (Lactuca sativa L.) makes the prospect of developing lettuce very promising. Bengkulu Province is dominated by inceptisol soil types which have low soil fertility, making it less optimal for lettuce growth. Giving organic matter can increase soil fertility through improving soil physical, chemical and biological properties so that it can support the growth of lettuce. This study aims to determine the dosage of manure, the dose of rice husk ash and the optimal dose interaction for lettuce growth and yield. This research was conducted from May 2018 to July 2018 in Medan Baru, Muara Bangkahulu Subdistrict, Bengkulu City. The research design used was a Completely Randomized Design (CRD) consisting of two factors and repeated 3 times. The first factor is the dosage of cow manure with three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha. The second factor is the dose of rice husk ash which consists of three levels, namely 0 tons/ha, 3 tons/ha, and 6 tons/ha. Data from the observations were analyzed statistically by Analysis of Variance (ANOVA) using the F test at the level of 5%. To determine the dosage of manure, the dose of rice husk ash and the optimal combination of doses for growth and yield of lettuce used the Polynomial Orthogonal method. The results showed that there was no interaction between cow manure and rice husk ash on the growth and yield of lettuce. The effect of cow manure has not shown the optimum dose for growth and yield of lettuce. The addition of manure doses up to 30 tons/ha was able to increase the value of plant height, number of leaves, leaf area, and fresh weighted plant weight of 0.189, 0.038, 0.931 and 0.104 respectively. Giving rice husk ash up to a dose of 6 tons/ha did not have a significant effect on all observed variables.
Limbah dari pertanian dan peternakan pada kawasan yang masyarakatnya bermata pencaharian sebagai petani ataupun peternak akan menimbulkan permasalahan lingkungan jika dibiarkan terus menerus tanpa adanya pengolahan terhadap limbah tersebut. Salah satu metode pengolahan limbah agro industri adalah pupuk organik. Pupuk organik adalah pupuk yang diproduksi dari materi makluk hidup seperti pelapukan sisa-sisa tanaman, hewan dan manusia. Pupuk organik ini dapat beruapa padatan dan cairan. Kandungan yang terdapat pada pupuk ini lebih kepada bahan organik dari pada kadar haranya. Penggunaan pupuk organik ini dapat meningkatkan perkembangan tumbuhan dan dapat mengurangi efek samping dari pupuk berbahan baku kimia yang lebih mahal. Pupuk organik dapat dibuat secara mandiri dan berkelompok dan lebih ramah lingkungan dan ekonomis dibandingkan pupuk sintetis. Tujuan kegiatan ini adalah untuk melatih keterampilan masyarakat pedesaan untuk membuat pupuk organik dengan menggunakan limbah agro industri mereka secara mandiri. Pengabdian dilaksanakan di Kecamatan Rambah Hilir Desa Pasir Utama Kabupaten Rokan Hulu Provinsi Riau. Proses pembuatan pupuk organik adalah dengan mencampur kotoran sapi dan cacahan jerami padi kemudian disiram dengan EM4 yang sudah diaktifkan dengan larutan air gula merah. Campuran ini kemudian didiamkan selama 4 minggu dan setiap 3 hari diaerasi agar proses fermentasinya berjalan baik. Metode yang digunakan dalam kegiatan adalah mengadakan pelatihan dan penyuluhan mengenai Teknologi pembuatan pupuk organik dari limbah agro industri masyarakat Desa Pasir Utama. Kegiatan ini juga mendukung program pemerintah untuk mendorong pertumbuhan pemanfaatan kembali limbah agro yang akan meningkatkan produktifitas pertanian masyarakat pedesaan.
