Abstract

The research aims to assess the yield of baby kale that can be consumed almost all of the parts and generate organic manure free. Field research was conducted in Sindon Village, Ngemplak, Boyolali in September to October 2016. The research method uses Randomized Complete Block Design factorial with two factors, these are the dosage of manure and the age of harvest. Manure consisted of 4 doses O1 (0 ton/ha), O2 (6 tons/ha) and O3 (8 tons/ha) and O4 (10 tons/ha), and age of harvest consisted of P1 (16 DAS), P2 (20 DAS), and P3 (24 DAS). Variables observed were plant height, number of leaves, internode length, fresh weight, dry weight, leaf area index, and harvest index. The result showed that age of harvest has significant influence plant height, internode length, the number of leaves, leaf area index, fresh weight, dry weight, and harvest index. Manure doses only influence dry weight. Manure dosage of 8 ton/ha and harvest age of 16 DAS is the best combination of baby kale. Manure dosage of 10 ton/ha and harvest age of 16 DAS produce baby kale that can be consumed almost in all parts of the plant with the highest harvest index that is equal to 0.83.

Abstract

One of problems faced by farmers in the rice cultivation with organic system is organic fertilizer limited, especially for farmers who do not have livestock. Azolla is one of materials that can be used as organic fertilizer. The aim of the research was to determine whether Azolla (Azolla mycrophylla L.) is able to meet the nutrient needs of some rice varieties on organic rice cultivation. The experiment used factorial complete randomized block design with three factors and three replications. Azolla was spread at days after transplanting and at 25 days after transplanting, 75% of Azolla was incorporated into soil and the rest was left up until rice were harvested. Meanwhile, cow manure was distributed after tillage. The treatment consisted of rice varieties (Mira1, Mentik Wangi and Red and White), Azolla (0 and 2 tons / ha) and manure (0 and 10 tons / ha). The result showed that Azolla did not significantly increase growth and yield of rice, despite it could increase the  N uptake 5,4% and P uptake P 17,3% , weight of dry straw, dry grain and 1,000 seeds by 5,86%, 12.7%, 7.37% than without Azolla respectively. Azolla 2 tons/ha with manure 10 tons/ha were able to increase N uptake by 7.6%, the uptake P by 13.7% and the of productive tiller number by 9.88%. From the standpoint of crop yields with organic system, a single use of Azolla has not been able to replace manure.

Abstract

Tujuan umum penelitian ini adalah memetakan potensi produksi emisi metana pada lahan sawah organik di Desa Sukorejo dan Jetis, Kecamatan Sambirejo, Sragen, yang dapat digunakan untuk memitigasi emisi metana dan meningkatkan produktivitas lahan. Secara garis besar pelaksanaan penelitian dibagi menjadi 4 tahap ; (1) karakterisasi tanah dan lahan, pengungkapan secara mendalam karakter obyek lahan pada setiap satuan penggunaan lahan sawah, (2) pengukuran potensi produksi emisi metana, dengan metode inkubasi sampel tanah di laboratorium, sampel gas yang dihasilkan dianalisis menggunakan kromatografi gas yang dilengkapi dengan flame ionization detector (FID) untuk menetapkan flux CH4, (3) analisa data, taraf perbedaan nilai potensi produksi metana diketahui dengan analisis beda nyata Uji T, dan penentuan faktor yang paling berperan terhadap besarnya potensi emisi metana dengan analisis stepwise regression, dan (4) rekomendasi, pemilihan rekomendasi didasarkan pada praktek budidaya pertanian yang efektif meningkatkan C organik dan menekan produksi emisi metana tanpa mengurangi produktivitas tanaman. Hasil penelitian menunjukkan bahwa ; (1) potensi produksi metana (CH4) berbeda nyata antar satuan penggunaan lahan (SPL) sawah di Desa Sukorejo dan Jetis, (2) iklim, varietas tanaman dan cara budidaya di daerah penelitian tidak signifikan mempengaruhi besarnya potensi produksi metana, dan (3) faktor yang berpengaruh signifikan terhadap besarnya potensi produksi metana di tanah sawah adalah potensial redoks (Eh). Hubungan Eh dengan besarnya potensi produksi metana berkorelasi negatif, artinya penurunan Eh akan menyebabkan peningkatan produksi metana. Mitigasi emisi GRK metana yang dapat dilakukan berdasarkan penelitian ini, bahwa potensial redoks adalah faktor utama penentu potensi produksi metana di dalam tanah sawah, maka alternatif yang memungkinkan adalah dengan pengelolaan air irigasi, yang dalam periode tertentu tanaman padi tidak diairi atau tidak digenangi, atau apabila kondisi air berlebih dilakukan drainase. Usaha ini dilakukan dengan tujuan kondisi tanah tidak terlalu reduktif atau potensial redoks tidak akan turun secara drastis, sehingga akan dapat menghambat aktivitas mikrobia methanogen dalam memproduksi metana.

Abstract

Tanaman cabai merupakan komoditas dengan  nilai ekonomis tinggi di Desa Srigading, Kecamatan Sanden, Kabupaten Bantul. Produktivitas cabai di lahan sub-optimal pasir pantai tidak kalah tinggi dibandingkan dengan lahan sawah. Namun penurunan produktivitas cabai yang disebabkan serangan organisme pengganggu tanaman mengakibatkan kerugian bagi petani, sehingga perlu dilakukan pengendalian OPT. Edukasi tentang pemanfaatan tanaman refugia sebagai pengendali hama alami belum pernah dilakukan. Metode yang dilakukan dalam kegiatan ini adalah paparan (edu-agriculture) tentang pemanfaatan tanaman refugia, pembuatan demonstrasi plot tanaman cabai dengan berbagai jenis tanaman refugia, serta inisiasi wisata swafoto bunga. Hasil kegiatan yang diperoleh berupa peningkatan pengetahuan mengenai teknik pengendalian hama dan penyakit secara alami sehingga mengurangi ketergantungan terhadap pestisida sintetik dengan memanfaatkan tanaman refugia yang terdapat di lingkungan sekitar. Kegiatan terbukti mengatasi permasalahan para petani dan memanfaatkan sumber daya alam secara maksimal yang sangat penting bagi peningkatan produktivitas pertanian.

Abstract

Bencana banjir akibat luapan Sungai Samin menjadi salah satu permasalahan utama di Kabupaten Sukoharjo. Perlu pengendalian bencana yang lebih menekankan pada pengurangan resiko (mitigasi). Masyarakat sebagai pihak pertama yang berhadapan dengan resiko bencana sehingga mitigasi lebih efektif dengan partisipasi aktif masyarakat. Penelitian bertujuan untuk memetakan potensi tingkat kerawanan banjir dan menganalisis upaya mitigasi bencana banjir melalui program pengembangan masyarakat tangguh bencana sebagai bentuk partisipasi masyarakat di Sub DAS Samin. Metode menggunakan teknologi sistem informasi geografis (SIG) dengan pendekatan map-overlay dan scoring beberapa peta parameter banjir (kemiringan lereng, jenis tanah, kerapatan drainase, curah hujan dan penggunaan lahan) dan survey wawancara untuk mengetahui upaya mitigasi yang diterapkan. Hasil menunjukkan bahwa tingkat kerawanan banjir wilayah Sub DAS Samin sebagian besar termasuk tingkat rawan ? sangat rawan yaitu seluas 53,826,73Ha (84,77%). Daerah yang termasuk kategori rawan ? sangat rawan berada di wilayah hilir dan tengah meliputi Kecamatan Mojolaban, Polokarto, Bendosari, Sukoharjo, Karanganyar, Jumapolo, Jaten, Karanganyar, dan Kebakkramat. Berdasarkan hasil analisis spasial dan wawancara bahwa Desa Tegalmade yang terletak di Kecamatan Mojolaban merupakan daerah dengan tingkat kerawanan bencana banjir tinggi. Hasil peta kerawanan bencana banjir dapat diintegrasikan sebagai sebuah rekomendasi dalam perencanaan tata ruang berbasis mitigasi bencana. Upaya mitigasi bencana banjir yang diterapkan yaitu dengan pengembangan masyarakat tangguh bencana di Desa Tegalmade. Pengembangan masyarakat tangguh bencana dilakukan melalui penyiapan infrastruktur berupa perbaikan tanggul secara permanen, perbaikan lingkungan berupa penanaman tanaman konservasi ?Bambu? di sempadan sungai, penyiapan kelembagaan dan kesiapsiagaan baik pemerintah terkait maupun masyarakat rawan bencana, sehingga potensi kerawanan banjir dan dampak yang ditimbulkan bisa diminimalisir.Kata kunci : kerawanan banjir, mitigasi, sig, masyarakat tangguh bencana
