Abstract

Penelitian ini bertujuan untuk mengevaluasi kesesuaian lahan tanaman Ubi Kayu (Manihot utilisima L) di Desa Bumela, Kecamatan Bilato, dengan fokus pada karakteristik dan kualitas lahan, kelas kesesuaian lahan, serta faktor pembatas dalam pengembangan tanaman Ubi Kayu (Manihot utilisima L). Penelitian dilaksanakan dari bulan Juli hingga Desember 2019, berlokasi di Desa Bumela, Kecamatan Bilato, Kabupaten Gorontalo. Metode matching digunakan untuk memadukan kriteria kesesuaian lahan dengan data kualitas lahan, dengan mempertimbangkan persyaratan tumbuh tanaman untuk mengidentifikasi kelas kesesuaian lahan yang sesuai. Pengolahan data melibatkan analisis karakteristik dan kualitas lahan, evaluasi kesesuaian lahan, identifikasi keunggulan wilayah, dan analisis ekonomi tanaman ubi kayu. Hasil penelitian menunjukkan bahwa di Desa Bumela, Kecamatan Bilato, kelas kesesuaian lahan yang potensial untuk tanaman ubi kayu (Manihot utilisima L) adalah kelas cukup sesuai (S2) dengan luas 80.568 ha atau 61,46%, sesuai marginal (S3) dengan luas 70,63 ha atau 0,53%, dan tidak sesuai (N) dengan luas 30.056 ha atau 22,92%. Kesesuaian lahan ini dipengaruhi oleh faktor pembatas seperti retensi hara, bahaya erosi, lereng, dan media perakaran. Dari hasil analisis keunggulan wilayah Kecamatan Bilato, terdapat dua komoditas unggulan, yaitu jagung dan ubi kayu. Selain itu, analisis ekonomi tanaman ubi kayu menunjukkan nilai R/C ratio yang menguntungkan, yaitu sebesar Rp. 1,23.

Kata Kunci: Kesesuaian Lahan, Ubi Kayu.

ABSTRACT

In Gorontalo Province, the Bulango Ulu irrigation area (D.I.) has the ability to build new paddy fields, although this potential is unknown, as is the level of soil fertility. The purpose of this study is to identify the variety of soil chemical properties and the level of soil fertility in the area. Three steps make up the soil fertility status technique: collecting soil samples on-site using survey and land observation methods, analyzing soil samples in the lab while examining the variety of soil chemical properties, and calculating soil fertility status using the deskwork methods. With the use of ArcGIS version 10, the analysis's output a spatial map of the distribution of soil fertility status in D.I. Bulango Ulu in Gorontalo Province is provided. The findings indicated that D.I. Bulango Ulu, Gorontalo Province still has a poor diversity of soil chemical properties. The fertility of the local soil is likewise poor.

ABSTRACT

This research aims to describe changes in the use of organic fertilizers in urban communities, both from the point of view of knowledge and behavior. This research was conducted in the period from February to April 2022. The population is urban in Gorontalo Province, with a random sample of 172 people with various professional characteristics. The research variables include people's perceptions, knowledge, and behavior regarding using organic fertilizers. Data were analyzed using descriptive statistics. The results showed that 95.3% of the urban community's perception of a suitable type of fertilizer chose organic fertilizer over non-organic fertilizer, and from the aspect of knowledge, as much as 69.8% knew the benefits of using organic fertilizer, both for plants and the environment and economic benefits. From the behavioral aspect, 83.7% of people are used to using organic fertilizers, and 62.8% prefer to use organic fertilizers compared to other fertilizers. The market potential for organic fertilizer for urban communities in Gorontalo Province based on aspects of knowledge and behavior is relatively high so that marketing can target urban communities. Communities can use agricultural shops with good reputations or images to obtain or trade organic fertilizers.

Keywords: Attitude, Citizen, Civil, Market, Organic Fertilizer.

tLactuca sativa L. has good economic prospects, but lettuce production often declines due to the unmet water requirement of lettuce. This study aimed to determine the water needs of lettuce on Inceptisol and Vertisol based on the Internet of Things (IoT). The location study was in the green house, Huluduotamo Village, Bone Bolango Regency, from September to October 2021, while the Vertisol and Inceptisol samples were from Sidomukti Village, Gorontalo Regency. This study used the Penman method with the Cropwat 8.0 application which was integrated with a smartphone through the Blynk (IoT) application. The water requirement yield of lettuce plants in September on Vertisol and Inceptisol in the early phase was 2.45 mm/day, the middle phase was 3.73 mm/day, and the final phase was 3.54 mm/day. Soil moisture detection device at field capacity moisture content produces 319 Analog Digital Converter (ADC) and soil in moist conditions reaches 534 ADC. The analog data value of the water content of the Inceptisol field capacity is 343 ADC and the soil in a moist state is 574 ADC. The performance of the device for detecting soil moisture in the water condition of the 15% field capacity of Vertisol and 22% Inceptisol is more effective than the gravimetric method.

Abstract

Penambahan luas lahan sawah penting dilakukan untuk meningatkan produksi padi sawah, tetapi informasi potensi lahan tersebut sering belum tersedia. Tujuan dilaksanakannya penelitian ini yaitu menentukan kelas kesesuaian lahan dan faktor pembatas penggunaan lahan untuk padi sawah, serta menilai kelayakan usahatani padi sawah. Pelaksanakan penelitian dari Juni hingga Agustus 2021 di wilayah Kecamatan Pinogu, Kabupaten Bone Bolango. Penelitian menggunakan metode pemadanan antara kriteria kesesuaian tanaman padi sawah dengan karakteristik lahan setiap satuan lahan, sehingga didapatkan kelas kesesuaian aktual dan faktor pembatas lahannya. Setelah faktor pembatas diperbaiki, maka didapatkan kelas kesesuaian potensial yang diteruskan dengan analisis kelayakan usaha padi sawah berdasarkan aspek finansial. Hasil analisis menunjukan bahwa secara aktual, kelas kesesuaian lahan didominasi sesuai marginal (kelas S3) diikuti cukup sesuai (kelas S2) untuk padi sawah di Kecamatan Pinogu Kabupaten Bone Bolango dengan pembatas adalah faktor kejenuhan basa. Selanjutnya, setelah perbaikan kelas dengan pemberian bahan organik dan kapur, maka secara potensial kelas kesesuaian lahan untuk padi sawah didominasi kelas S2 diikuti kelas S1 (sangat sesuai). Usahatani padi sawah di wilayah ini relatif menguntungkan karena R/C rasio lebih besar 1.
