Abstract

Wonogiri Regency is one of the main areas for porang cultivation and processing centers. As a center, market conditions in Wonogiri Regency are still monopsony, giving rise to very different prices between farmers and final consumers. This is due to the involvement of many parties in it. The aim of this research is to find out whether the marketing channels for porang commodities in a monopsony market are efficient or not. The method for determining the location was carried out purposively in four sub-districts in Wonogiri Regency are Karangtengah, Jatisrono, Slogohimo dan Manyaran. The number of respondents was 60 farmers and 9 traders taken using snowball sampling. This research uses descriptive and quantitative methods. Based on the results of analysis, the form porang commodities are divided into two, namely fresh tubers and chips. The research results show that the marketing channel in the form of fresh tubers is classified as inefficient for all channels. Meanwhile, marketing channels in the form of porang chips are considered efficient for all channels, where the most efficient channel is channel 3 (Farmer à Farmer Owner Delevery Order (DO) à Factory).

Abstract

Kismantoro district is a karst land with unique characteristics and its physical health is easily influenced by land use. The purpose of this study was to identify the physical health status of soil, and find the influence of land use and parameters that limit soil physical health, which eventually provide appropriate land management strategies and recommendations to improve soil health. The research was conducted using a descriptive explorative approach and a purposive sampling method on the 12 Land Map Units (LMU) with three replications. Data were analysed using Analysis of Variance and Pearson correlation. Results indicated that most soil physical health in agricultural land in Kismantoro District is healthy. The highest soil physical health status was found on plantation agricultural land, with the average of the soil physical health being high status of 63.22%, followed by moor agricultural land at 52.83% and rice fields at 48.2%. The determinant factors of soil physical health were soil porosity, bulk density, and soil texture. To enhance the physical health of agricultural soil in Kismantoro District, it is recommended to apply organic matter, adopt zero or no-tillage practices, and grow cover crops on agricultural land.  Keywords: determinant factor, soil compaction, soil texture, sustainable management, เว็บสล็อต.

Abstract

High rainfall caused the overflow of the Wiroko river, causing flooding in Nguntoronadi. This study aims to analyze flood potential, provide evaluation and recommendations on areas that have high flood suscetibility. Type of research is quantitative descriptive by using the overlay method of scoring land characteristics that affect environmental conditions.  Land characteristics are rainfall, altitude, slope, soil type and land use. The characteristics of the land  are overlayed using the ArcGIS application to determine a map of flood susceptibility index, and the data were analyzed using descriptive methods. The result found three categories of flood susceptibility indexes: low, medium, and high. The study revealed a total area flood susceptibility of 6566.52 ha, with 33.79% having high flood susceptibility. The potential for high flood vulnerability is found in lowland, high rainfall and open land use. Areas which has a high flood susceptibility by improving river flow, drainage and terraces in rice fields. The high flood susceptibiity caused by rainfall, lowland and low vegetation as well as high human populations.

Abstract

Lahan pasir pantai di Dusun Sogesanden, Desa Srigading, Kecamatan Sanden, Kabupaten Bantul, Daerah Istimewa Yogyakarta merupakan lahan sub-optimal yang memiliki keterbatasan biofisik lahan. Permasalahan utama budidaya di lahan pasir yaitu rendahnya efisiensi dan efektivitas penyiraman. Diperlukan sistem irigasi yang efisien dan efektif untuk menyediakan lengas yang cukup bagi tanaman. Tujuan penelitian ini adalah merakit dan mengimplementasikan teknologi automasi irigasi tetes pada lahan budidaya kacang tanah (Arachis hypogaea L.). Teknologi ini mampu memberikan air secara tepat kebutuhan dan sasaran yaitu pada zona perakaran tanaman. Metode yang digunakan adalah perakitan automasi sistem irigasi dengan alat monitoring kelembapan dan aplikasi penyiraman di lahan budidaya pasir pantai. Hasil penelitian menunjukkan bahwa sistem automasi irigasi telah berhasil dirakit dan diaplikasikan pada lahan pasir pantai, sistem berfungsi dengan baik. Sensor tanah mampu membaca kondisi lengas tanah dan mengirimkan data ke controller. Layar pada LCD menujukkan nilai kondisi lengas > 700 jika tanah dalam kondisi kering dan nilai lengas ≤420 jika tanah dalam kondisi basah. Keran otomatis akan membuka (>700) sehingga air dari tandon akan mengalir melalui selang menuju perakaran tanaman dan keran otomatis akan menutup dan menyetop aliran air dari tandon jika nilai lengas ≤420. Diperoleh efisiensi tenaga kerja siram mencapai 100% setelah menggunakan teknologi automasi irigasi irigasi tetes.
