Abstract

Title : Paddy Soil Quality Management Modeling in District of Jatipuro, Karanganyar Regency. The intensive paddy soil management were known caused the soil degradation, thus the proper paddy soil quality management was needed to maintain the sustainability of soil function. The aim of the research was built a model that can be used as the reference of paddy soil quality management in district of Jatipuro, Karanganyar regency. The research was executed on October 2008 until February 2009. The research was descriptive explorative, carried out by collecting secondary data for model building and getting sample based on random sampling method at paddy soil in each Soil Map Unit (SMU), laboratory analysis for each selected soil quality indicator, and field observation for model validation. The results showed that the builded model: SQi = 0,414 + 0,363 pH, can be used as the reference of paddy soil quality management in district of Jatipuro. Based on the model then the recommendation of paddy soil quality management could be determined, through increasing pH by submerged the soil and delay the rice planting about 2 weeks after flooding. Keywords: model, paddy soil quality, district of Jatipuro

Abstract

Title : Diversity and Ecological Services of Epigeic Macrofauna in Carrot Crop (Daucus carota L.) with Some Proportions of Organic and Inorganic Fertilizers. Recently ecological services by macrofauna diversity to sustainable production function of agroecosystem got a lot of attention. Epigeic macrofauna is diverse of macrofaunas which their life and activities are on the land surface, act as decomposer, litter transformer, and`predator, so they are important to keep ecosystem stability. Inorganic fertilizer usage continually on carrot crop without organic fertilizer can reduce soil macrofauna diversity. Improvement can be done by the use of organic and inorganic fertilizer equally. The aim of this research was to measure epigeic macrofauna diversity and their ecological services to carrot production by giving some proportions of organic and anorganic fertilizer. The research conducted in the end of December 2007 in a farmer field in Tawangmangu. It use RAKL (Random Completly Block Design) with single factor treatment. The treatment was fertilizer type usage proportion of organic and inorganic fertilizer. They were composed of 9 proporsition composition as follows: control, 50% inorganic fertilizer, 100% inorganic fertilizer, 50% organic fertilizer, 50% organic fertilizer added by 50% inorganic fertilizer, 50% organic fertilizer added by 100% inorganic fertilizer, 100% organic fertilizer, 100% organic fertilizer added by 50% inorganic fertilizer, 100% organic fertilizer added by 100% inorganic fertilizer. 100% inorganic fertilizer were composed of Urea 150 kg ha-1, SP 36 200 kg ha-1, and KCL 100 kg ha-1. 100% dosage organic fertilizer was 20 tons ha-1. To recognize the treatment effect is done by F test and close relationship among variables tested by corelation analysis. The result showed that organic and inorganic fertilizer proportion didn’t significant to diversity, population dencity and biomass epigeic macrofauna, but affected to β caroten content of carrot. Hymenoptera was dominant macrofauna in carrot crop. Macrofauna function to increase β caroten of carrot is indirect. Key words: fertilizer proportion, epigeic macrofauna,  caroten, Hymenoptera, ecological service

Abstract

Masyarakat desa Kebonagung, Kec.Sidoharjo, Kabupaten Wonogiri mempunyai visi ingin mengembangkan desanya menjadi desa agrowisata organik terpadu. Saat ini, di desa Kebonagung telah dikembangkan padi organik dan buah naga organik. Masyarakat ingin mengembangkan tanaman lada secara organik, baik sebagai tanaman pagar maupun di tanam di lahan pekarangan mereka, karena lada bernilai ekonomi tinggi. Permasalahan yang dihadapi adalah mereka belum mengetahui teknologi budidaya lada secara organik, dan juga belum mengetahui apakah lahannya sesuai untuk untuk budidaya lada atau tidak. Kegiatan pengabdian ini bermitra dengan: (1) Asosiasi Pertanian Organik “Wono Agung” (APOW) dan (2) Kelompok Tani Sedya Maju. Kedua mitra berlokasi di desa Kebonagung.Tujuan dari program ini adalah: (1) alih teknologi dari perguruan tinggi kepada mitra tentang budidaya tanaman lada secara organik sehingga mitra mengembangkan lada secara organik dengan teknologi penanaman secara benar, maupun (2) memberikan informasi ilmiah tentang kesesuaian lahan di Kebonagung untuk budidaya tanaman lada. Metode yang digunakan meliputi: focus group disccusion (FGD), penyuluhan, praktik budidaya lada organik, dan pemantauan. Hasil menunjukkan bahwa mitra begitu antusias dalam menerima teknologi yang dibagikan karena memiliki pengharapan lada mempunyai nilai jual yang tinggi, dan mereka juga segera mempraktikkan budaya lada dari bibit yang dibagikan secara cuma-cuma. Berdasarkan hasil kajian ilmiah, desa Kebonagung sesuai untuk budidaya lada organik dengan pengelolaan tertentu.
