Abstract

The aim of the research was to find out the pattern of corn agricultural processing activities that were consistent or not carried out by farmers and the impact of the corn processing process in Gorontalo Regency..The data collection method used a questionnaire, and the sample in this study was the Gorontalo Regency Corn Farmers Association (GAPOKTAN) which was determined using the slovin formula with an estimation error of 10%. The method of collecting data on corn processing activities uses the Proportional Random model with a population of land managed by corn farmers in Gorontalo Regency. Data analysis for drawing conclusions using the Guttman approach. The results of the study found patterns of corn agricultural processing activities in Gorontalo District that were consistently carried out, namely on pre-planting indicators including land clearing using pruning machines, use of pesticides, and burning of straw biomass and pastures. The indicators for planting the types of seeds used are Bisi and NK in one year 2 harvests. Treatment indicators include: the use of synthetic fertilizers, and the use of weed killer pesticides, harvest indicators include the activity of picking up the harvest, peeling, and delivering the harvest to the point of sale. In the processing of land, farmers have an advantage if the yield is above 5 tons and a loss if the yield is below 3 tons. The findings from this study are that the pattern of corn agricultural processing activities in the form of burning biomass, burning energy from conventional machines, and using fertilizers and pesticides is very massive which has an impact on environmental damage.

Abstract

Penelitian ini bertujuan mengidentifikasi perubahan tutupan hutan dalam waktu 10 tahun (periode 2013-2022) yang ada di wilayah Unit Pemukiman Terpadu (UPT) Desa Saritani Kabupaten Boalemo, Provinsi Gorontalo. Metode yang digunakan pada penelitian ini adalah model pengindraan jauh, melalui data-data delineasi dari Google Earth dalam periode waktu 2013-2022 kemudian dianalisis dengan software ArcGis. Hasil penelitian menunjukkan bukaan tutupan lahan pada tahun 2013 sebesar 348.30 ha, 602,82 ha pada tahun 2018 dan 1138,39 ha pada tahun 2022. Temuan ini menunjukkan dalam waktu sepuluh tahun terakhir bukaan tutupan lahan mengalami perluasan hingga 300%. Kondisi ini dapat memicu kerusakan lingkungan serius apabila pengelolaan lahan pertanian di Desa Saritani dikelola secara tidak berkelanjutan. Penanaman jagung di lahan miring dapat memicu erosi dan sedimentasi sehingga membuat tanah semakin tidak produktif. Hasil dari penelitian ini diharapkan dapat menjadi acuan dan bahan informasi dalam pengambilan kebijakan khususnya di wilayah pertanian Desa Saritani yang berbatasan langsung dengan wilayah konservasi

Abstract

This study aims to describe the status of soil fertility and corn yield on different slopes of agricultural land in UPT SP3 Saritani Village, Boalemo Regency. The study used survey methods at 3 land slope locations (20--30%, 30–40%, and 50–60%), determined purposively. Soil samples and maize yields were analyzed quantitatively and descriptively. Corn yields were collected and compared over 3 harvesting seasons based on the parameters of agronomic components. Soil fertility was analyzed at BSIP PALMA Manado laboratory, with parameters including macronutrient components. An essential finding of this study is that there is a difference in corn yield and nutrients on the sloping lands. The fertility status of farmers' land on the average sloped land of the three stations is very low levels of nitrogen and carbon nutrients and high levels of phosphate and potassium. The agronomic components of Stations 1 and 2 were relatively similar compared to the yield of components at Station 3. In the 3 harvest seasons, Station 1's yield decreased every season; from Station 2 it also decreased, but only at the time of the third harvest, although it was insignificant. The yield from Station 3, the steepest field, decreased significantly. Keywords: bisi 18 hybrida, maize, sloping land, soil fertility
