Abstract

Soil moisture and temperature are parameters of soil physical properties that are closely related to climatic variations. Descriptive Research on "Variation of Moisture Regime and Soil Temperature on Land with Low Cloud Cover" has been done, to determine the variation of soil moisture and soil temperature on land with permanently low cloud cover based on the Terra Modis map on the island of Lombok. Low cloud cover data was obtained from Terra Modis satellite data which were delineated by Lombok maps. Daily rainfall data were collected from the Climatology Meteorology and Geophysics Agency (BMKG) Kediri Station. Moisture and soil temperature were measured periodically at 10 day intervals, for two consecutive months (March and April, 2020). The results showed that soil moisture varied temporally. Soil moisture content was higher in areas with low cloud cover in the dryland with soils type of Typic Eutrudept, Inceptisols order, than in areas without cloud permanent cover. Soil temperature in the open zone (without low cloud cover) was higher than in the zone that always experiences closure

Abstract

Agroforestri sebagai bentuk kaidah konservasi dalam menjaga produktivitas lahan. Berbagai variasi yang ada pada agroforestri akan dapat memperbaiki sifat fisika tanah terutama nisbah dispersi dan stabilitas agregat tanah, sifat fisika ini akan membantu dalam menahan tekanan atau gaya dari butiran air hujan yang jatuh. Tujuan dalam penelitian ini yaitu untuk mengetahui pengaruh penggunaan lahan sistem agroforestri terhadap nilai nisbah dispersi dan stabilitas agregat tanah di lahan miring. Metode penelitian yang digunakan adalah metode deskriptif dengan pengambilan sampel dilakukan secara diagonal. Ada 3 sistem agroforestri (agroforestri berbasis cengkeh, agroforestri berbasis kopi dan agroforestri berbasis durian) yang dikaji dengan 3 ulangan dengan posisi di hulu, tengah dan hilir. Penelitian ini dilaksanakan pada bulan Januari-Juni 2020 di Desa Santong, Kecamatan Kayangan, Lombok Utara. Ada dua parameter utama yang diuji yaitu nisbah dispersi dan stabilitas agregat tanah. Hasil penelitian menunjukkan bahwa rata-rata nilai nilai nisbah dipersi tanah ditunjukkan oleh agroforestri berbasis kopi sebesar 79,85% dan yang tertinggi berada pada agroforestri berbasis cengkeh sebesar 91,56%, nilai-nilai tersebut tergolong ke dalam kelas sangat terdispersi. Berbeda halnya dengan stabilitas agregat tanah, rata-rata nilai stabilitas agregat tanah yang tertinggi ditunjukkan pada agroforestri berbasis kopi sebesar 109 dan yang terendah ada pada agroforestri berbasis cengkeh sebesar 60. Nilai stabilitas agregat tanah jika diinterpretasikan agroforestri berbasis kopi termasuk ke dalam kelas sangat mantap dan agroforestri berbasis cengkeh termasuk kelas agak mantap. Agroforestri berbasis kopi sangat baik diplikasikan di lahan miring agar erosi tanah dan produktivitas lahan dapat dipertahankan.

Abstract

The Porang plant (Amorphophallus muelleri Blume) is one of the plants included in the ranks of superior food commodities that greatly support the economy of the people and the country. The purpose of this study was to determine the class of land suitability for Porang plants (Amorphophallus muelleri Blume), the class of land suitability for various shade crops, and the most suitable shade for Porang Plants in Bayan District, North Lombok Regency. This research was conducted using a descriptive method with survey techniques that included a series of basic map making activities and eight surveys. Data from field surveys and laboratory analysis were analyzed using the matching method. The results of this study show that the characteristics of the land in the research location of Porang planting land (Amorphophallus muelleri Blume) and Shade Plants in Bayan District, North Lombok Regency are included in the characteristics of land with a level of suitability between very appropriate (S1), quite appropriate (S2), marginal (S3), and not appropriate (N).
