Abstract

Limbah industri kelapa sawit yang memiliki potensi untuk dijadikan pupuk organik dan tersedia cukup banyak di Provinsi Riau adalah abu boiler. Penelitian ini bertujuan untuk menentukan dosis abu boiler kelapa sawit terhadap tanaman selada. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non faktorial terdiri dari 4 perlakuan dan 3 ulangan yaitu: P0 (Kontrol), P1 (176 g abu boiler kelapa sawit), P2 (352 g abu boiler kelapa sawit), dan P3 (528 g abu boiler kelapa sawit). Parameter yang diamati meliputi tinggi tanaman (cm), jumlah daun (helai), dan lebar daun (cm). Berdasarkan hasil ANOVA pada taraf 5%, pemberian abu boiler kelapa sawit pada memberikan pengaruh terhadap tinggi tanaman, jumlah daun, dan lebar daun tanaman selada. Dosis abu boiler kelapa sawit  terbaik pada tinggi tanaman, jumlah daun, dan lebar daun  tanaman selada adalah 352 g/polybag. The industrial palm oil waste with potential to be used as organic fertilizer and abundantly available in Riau Province is boiler ash. This study aims to determine the optimal dosage of palm oil boiler ash for lettuce plants. The research employed a Randomized Block Design (RBD) consisting of 4 treatments and 3 replications, namely: P0 (Control), P1 (176 g of palm oil boiler ash), P2 (352 g of palm oil boiler ash), and P3 (528 g of palm oil boiler ash). Observed parameters included plant height (cm), number of leaves (pieces), and leaf width (cm). Based on the results of ANOVA at a 5% significance level, the application of palm oil boiler ash significantly influenced the height, number of leaves, and leaf width of lettuce plants. The optimal dosage of palm oil boiler ash for plant height, number of leaves, and leaf width was 352 g/polybag.

Abstract

Fungi Mikoriza Arbuskular (FMA) merupakan jamur yang bersimbiosis dengan perakaran tumbuhan tingkat tinggi. FMA dapat berperan sebagai agen biokontrol dan biofertilizer. Studi ini bertujuan mengetahui jenis-jenis FMA pada rhizosfer tanaman kacang tanah di Nagari Sawah Tangah, Kecamatan Pariangan, Kabupaten Tanah Datar dan sebagai tahapan awal dalam pemanfaatan FMA sebagai agen biokontrol dan biofertilizer. Sebanyak lima sampel tanah diambil menggunakan teknik purposive random sampling. Sampel tanah yang diperoleh disaring menggunakan teknik penyaringan basah. Identifikasi spora FMA dilakukan hingga tingkat genus berdasarkan karakteristik morfologi, yakni bentuk, warna, serta ornamentasi spora. Hasilnya menunjukkan bahwa jumlah spora FMA tertinggi pada rhizosfer tanaman kacang di Nagari Sawah Tangah, Kecamatan Pariangan, Kabupaten Tanah Datar adalah dari genus Glomus (3 tipe), yakni Glomus sp-1 sebanyak 15 spora, Glomus sp-2 sebanyak 12 spora, dan Glomus sp-3 sebanyak 74 spora (total 101 spora). Jumlah tertinggi kedua adalah dari genus Acaulospora (1 tipe) sebanyak 27 spora, sementara jumlah spora FMA terendah adalah dari genus Gigaspora (1 tipe) sebanyak 9 spora per 100 gr sampel tanah. Arbuscular Mycorrhizal Fungi (AMF) are fungi that have a symbiotic relationship with the roots of higher plants. AMF can act both as biocontrol agent and biofertilizer. This study aims to determine the types of AMF in the rhizosphere of peanut plants in Nagari Sawah Tangah, Pariangan Subdistrict, Tanah Datar Regency, as an initial stage in the application of AMF as a biocontrol agent and biofertilizer. Five soil samples were taken using a purposive random sampling technique. The soil samples obtained were then filtered using a wet filtration technique. Identification of AMF spores was carried out at the genus level based on their morphological characteristics, namely shape, color, and spore ornamentation. The results reveal that the highest number of AMF spores in the rhizosphere of peanut plants in Nagari Sawah Tangah, Pariangan Subdistrict, Tanah Datar Regency is from the genus Glomus (3 types), namely Glomus sp-1 with 15 spores, Glomus sp-2 with 12 spores, and Glomus sp-3 with 74 spores (a total of 101 spores). The second highest number is from the genus Acaulospora (1 type) with 27 spores, and the lowest number of AMF spores is from the genus Gigaspora (1 type) with 9 spores per 100 gr of soil sample.
