Abstract

The rice productivity in Panai Tengah was still relatively low, producing 4.75 Mg ha-1, compared to the national production of 5 to 6 Mg ha-1. Low rice productivity was caused by limiting factors in land use, namely, physical and biological factors, soil chemistry, and agricultural systems. Providing organic fertilizer or municipal waste compost is one way to overcome the constraints on the soil’s physical, biological, and chemical characteristics. This study aims to determine the response to the growth and yield of rainfed rice fields in Kecamatan Panai Tengah with a dose of Municipal Solid Waste Compost (MSWC). This research was conducted by taking soil samples in the rainfed rice fields and then analyzing them in the experimental field at the Faculty of Science and Technology, Labuhanbatu University. The analysis stage was for six months, from seeding to harvesting. The methodology for this study was a non-factorial randomized block design consisting of 7 treatments. The result showed that applying MSWC at a dose of 18 Mg ha-1 showed high yields. The recommendation to farmers was to give 18 Mg ha-1 of MSWC to increase the yields of their rice fields.

Abstract

Pengkajian ini bertujuan untuk mengkaji tingkat motivasi pekebun dan faktor-faktor yang mempengaruhi motivasi pekebun dalam penerapan sistem tanam hole in hole. Pengkajian ini dilaksanakan pada bulan April 2022 sampai dengan bulan Juni 2023. Metode pengumpulan data yaitu metode kombinasi yang terdiri dari observasi, wawancara, dan kuesioner yang sudah diuji validitas dan reliabilitasnya. Selanjutnya metode analisis data menggunakan regresi linear berganda. Hasil pengkajian menunjukkan tingkat motivasi pekebun dalam menerapkan sistem tanam hole in hole tanaman kelapa sawit pada lahan gambut tergolong dalam kategori sangat tinggi dengan persentase sebesar 84,92%. Hasil analisis regresi linear berganda terhadap faktor-faktor yang mempengaruhi motivasi pekebun diperoleh persamaan sebagai berikut Y= 16,280 + 0,084X1 + 0,322X2 + 0,0000003321X3 + 0,129X4 – 0,387X5 + 0,033X6 + 0,403X7 + 0,281 X8 + e. Uji F (simultan) menunjukkan bahwa variabel-variabel bebas pendidikan formal (X1), pendidikan non formal (X2), pendapatan (X3), luas lahan (X4), jumlah tanggungan (X5), pengalaman berusahatani (X6), peran penyuluh (X7), dan akses informasi (X8) berpengaruh signifikan secara simultan terhadap variabel terikat motivasi pekebun (Y). Selanjutnya uji t (parsial) menunjukkan bahwa variabel (X2), (X3), (X5), (X6), (X7), dan (X8) memiliki pengaruh yang signifikan terhadap (Y). sedangkan variabel (X1) dan (X4) tidak berpengaruh terhadap (Y).
