Abstract

Uncontrolled land conversion causes reduced land area for plant cultivation. The alternative used for rice cultivation is the marginal land such as sandy soil, however, several constraints led to very low productivity, so it needs proper management such as the addition of organic matter. The purpose of this study was to determine the changes in the chemical properties of sandy soil treated with Azolla microphylla and quail manure. The pot research was carried out in the Greenhouse of the Faculty of Agriculture, Universitas Sebelas Maret, with a factorial Completely Randomized Design (CRD) method, with 2 factors. Factor I was Azolla microphylla (A) (A0= 0, A1= 50, A2= 100, A3= 150 tons ha-1). Factor II was quail manure (Q) (Q0= 0, Q1= 20, Q2= 40 tons ha-1). Azolla microphylla and quail manure were incubated for 14 days under anaerobic conditions. The results showed that the application Azolla microphylla and quail manure increased chemical properties on sandy soil significantly. The addition of Azolla microphylla (100 tons ha-1) and quail manure (40 tons ha-1) increased the chemical properties of sandy soil such as cation exchange capacity (CEC), available-P, ammonium, available-K, available-Ca, electrical conductivity (EC) and redox potential (Eh).

Abstract

The higher national rice demand encourages various efforts to increase rice production. This increase in rice production occurs in line with increasing public awareness of healthy foods, especially organic rice. Rice field management with an organic system is expected to provide a higher yield and quality of rice. This study aims to determine the effect of the long-time application of an organic rice management system on rice yield and quality. Descriptive exploratory research is supported by laboratory analysis of samples of organic rice plants with three periods (10 years, 7 years, and 4 years), semi-organic and conventional. The parameters observed were dry harvested grain, dry milled grain, the weight of 1000 grains, unfilled grain, protein content, amylum, amylopectin, and reducing sugar. The most prolonged organic rice field management with the application of 10 years gives better results with a protein content of 6.14%, amylum 71.71%, and amylopectin 49.35%. While the application of organic farming for 7 years gives the highest rice yield, the difference is not confirmed with the application of organic 10 years, with the weight of dry grain harvest 10.44 Mg ha-1, dry milled grain 8.15 10.44 Mg ha-1, the weight of 1000 grains 24 g, and unfilled grain 3.8%.

Abstract

One of the Indonesian provinces where the agricultural industry drives the economy is Punung, Pacitan, which has local conditions that are particularly suitable for producing citrus, giving this product the potential to continue to expand in popularity. Land evaluation tries to provide information on its potential for a particular purpose. This research was conducted to know land suitability classes, limiting factors, and improvement efforts that can be made. This research is exploratory descriptive with a variable approach through field survey and using a purposive random sampling method based on Land Mapping Units. Data analysis was carried out using the matching method between land characteristics and conditions for growing citrus, a statistical test by ANOVA (Analysis of Variance), and Duncan’s Multiple Range Test (DMRT) to find the factors that most determine land characteristics in Punung. The study results show that the actual land suitability class in Punung is marginally suitable. Improvements that can be made to increase the availability of nutrients in the soil in the form of available P2O5 with a low level of management is to apply P fertilization according to the needs of citrus. ANOVA results proved that the variety of soil types significantly influences some of the land characteristics.

Abstract

Pangalengan is a horticultural crop center area in Bandung Regency. The soil in this area consist of Andisol, which is developed from volcanic ash. One of the primary commodities in this area is potatoes. Intensive farming in Pangalengan is a problem that has an impact on soil and environmental conditions, thereby disrupting crop productivity. The research aimed to assess the characteristics of Andisols for the development of potato crop in Pangalengan. This research used qualitative, descriptive, and survey methods. The survey based on physiographic methods. Soil samples were taken purposively. The observations consisted of soil characteristics, erosion, soil fertility and land suitability. The research results show that the soil type is Typic Hapludans. Erosion is moderate (19.06-94.41 tons/ha/year) in SMU 1 and 2, high (311.22 tons/ha/year) in SMU 3 and very high (798.04 tons/ha/year) in SMU 4, soil fertility is low with land suitability for potato crop including marginally suitable (S3) and not suitable (N). Fertilization, especially P fertilizer and organic fertilizer as well as making bunds in the direction of the contour, are recommended for the development of potato crops in Pangalengan.

Abstract

Soil compaction is one of the problems faced due to land conversion in agriculture, directly impacting land productivity. This study aimed to identify the distribution of soil density with the Dynamic Penetration Index (DPI) method, the influence of land use, and the determinants of soil compaction, and provide recommendations to control soil density on agricultural land around the sub-watershed area. This research used an exploratory descriptive method, and sample points were determined by purposive sampling. There are 45 sample points determined based on the overlay map of soil type, land use, slope, and rainfall. The low DPI class has an area of 8,227 ha (34.34%), and the very low DPI class has an area of 15,729 ha (65.65%). The highest DPI value was in the plantation land use, and the lowest was in the rice field land use. Plantations experienced soil compaction due to intensive land use without soil quality restoration. The determining factors that affect soil compaction were porosity and bulk density. High porosity means low DPI values and, therefore, low compaction. High bulk density means high DPI value and therefore high compaction. Recommendations for land management include adding organic matter and tillage using a hoe or tractor to optimize soil compaction.

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.
