The capacity of farmers to manage environmentally friendly paddy rice is closely related to individual behavior towards technological innovations that are applied and disseminated. This study aims to determine the productivity of paddy rice with an environmentally friendly management approach. The research was conducted in Merauke Regency, Papua Province, from July to November 2018 during the gadu planting season (MT II). The design used was a factorial Randomized Block Design (RBD) with 4 child factors, each variety used was Bawor 9, Black Madras, M70, Sertani 8. The results showed that the treatment of four varieties differed on plant height, number of tillers , panicle length, weight 1000 Grains, harvest grain weight, grain dry grain weight, empty grain amount, rice grain amount and heavy stover. \u0000Keywords: Management, Paddy rice, Environmental friendly \u0000Sebagian besar petani padi sawah belum memberikan respon yang tepat atas inovasi pengelolaan sawah yang ramah lingkungan, karena kemampuan atau kapasitas yang dimiliki petani belum mampu mendukung dalam menghasilkan produk-produk usahatani yang ramah lingkungan dan berkelanjutan.

The objectives of this study include: 1) comparing the volume of water given with a frequency of 1, 2 or 3 days for NPK nutrient availability on regosol soils; 2) determining the amount of NPK nutrients available after 30 days of incubation by giving different compost doses; 3) determining the interaction between the frequency of water supply and decomposition of organic matter in providing NPK nutrients to regosol soils. This study used a completely randomized design method with a 3 × 3 factorial pattern with 3 replications, therefore there were 27 experimental units. Data analysis of the observed variables was done using variance analysis with SAS program ver 9.0 and if there was a real treatment effect followed by a different test between treatments using BNT (5%).

Storage media and storage period significantly affected germination and vigor indexes but did not significantly affect germination rates. The results showed that the sawdust storage media was a good medium for storing clove seeds (Syzygium aromaticum L.). This can be seen in the results of the average germination of clove seeds stored in powder storage media with a storage time of 10 days giving better results of 85% compared to rice husks at a storage time of 10 days with a germination percentage of 65%.  \u0000Keywords: clove seeds, save media, save period \u0000  \u0000ABSTRAK \u0000Penelitian ini bertujuan untuk menguji pengaruh media dan periode simpan terhadap viabilitas benih cengkeh. Penelitian dilaksanakan di laboratorium Balai Besar Perbenihan dan Proteksi Tanaman Perkebunan Ambon. Penelitian menggunakan rancangan acak lengkap pola faktorial dengan dua macam faktor dan tiga kali ulangan. Media simpan terdiri dari 3 taraf yaitu: Tanpa media simpan, media simpan sekam padi dan media simpan serbuk gergaji. Faktor kedua adalah periode simpan terdiri dari 4 taraf yaitu: penyimpanan 10 hari, penyimpanan 20 hari, penyimpanan 30 hari dan penyimpanan 40 hari. Parameter yang diukur adalah daya berkecambah, laju perkecambahan dan indeks vigor. Media simpan dan periode penyimpanan berpengaruh nyata pada persentase perkecambahan dan indeks vigor tetapi tidak berpengaruh nyata pada laju perkecambahan. Hasil penelitian menunjukan bahwa media simpan serbuk gergaji merupakan media yang baik bagi penyimpanan benih cengkeh (Syzygium aromaticum L.). Hal ini terlihat pada hasil rata-rata daya berkecambah benih cengkeh yang disimpan pada media simpan serbuk dengan lama penyimpanan selama 10 hari memberikan hasil yang lebih baik yakni 85% jika dibandingkan dengan sekam padi pada lama penyimpanan 10 hari dengan persentase perkecambahan 65%. \u0000Kata Kunci: benih cengkeh, media simpan, periode simpan","PeriodicalId":253388,"journal":{"name":"JURNAL BUDIDAYA PERTANIAN","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123891273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was carried out in Wae Ruhu Watershed, Sirimau Subdistrict, Ambon City in August - September 2018. This research was divided into three stages, namely the research preparation stage which included secondary data collection, making land unit maps, fieldwork maps, flood hazard maps. The field research phase includes observing and verifying flood parameters, verifying the extent of flood vulnerability, observing position, density, building construction, and data analysis and reporting stages that produce flood hazard maps and maps of flood-prone residential areas. The results showed that the high vulnerability had an area of ​​60 ha or 3.68%, the medium vulnerability level was 1096 ha or 67.28% and the low vulnerability level was 473 ha or 29.04%. The results of the study also obtained the position of settlements already in the river border even on the banks of the river, the density of settlements were divided into two, namely: 1) densely populated class settlements (99.6%); and 2) infrequent density class settlements (30.5%), and permanent settlement construction , multilevel and not terraced. \u0000Keywords: flood, settlement, vulnerability \u0000  \u0000ABSTRAK \u0000Penelitian ini bertujuan memetakan tingkat kerawanan banjir dan sebarannya di DAS Wae Ruhu, mengevaluasi wilayah permukiman yang berada pada tingkat kerawanan banjir yang berbeda di DAS Wae Ruhu. Penelitian ini dilaksanakan pada DAS Wae Ruhu Kecamatan Sirimau Kota Ambon pada bulan Agustus – September 2018. Penelitian ini terbagi menjadi tiga tahap yakni tahap persiapan penelitian yang meliputi pengumpulan data sekunder, pembuatan peta satuan lahan, peta kerja lapangan, peta kerawanan banjir. Tahap penelitian lapangan yang meliputi pengamatan dan verifikasi parameter banjir, verifikasi batas tingkat kerawanan banjir, pengamatan posisi, kepadatan, kostruksi bangunan serta tahap analisis data dan pelaporan yang menghasilkan peta tingkat kerawanan banjir dan peta wilayah permukiman rawan banjir. Hasil penelitian diperoleh tingkat kerawanan tinggi memiliki luas 60 ha atau 3,68%, tingkat kerawanan sedang memiliki luas 1096 ha atau 67,28% dan tingkat kerawanan rendah memiliki luas 473 ha atau 29,04%. Hasil penelitian juga di peroleh posisi permukiman sudah berada di sempadan sungai bahkan di bantaran sungai, kepadatan permukiman dibagi atas dua yaitu: 1) permukiman kelas kepadatan padat (99,6%); dan 2) permukiman kelas kepadatan jarang (30,5%), serta konstruksi permukiman permanen, bertingkat dan tidak bertingkat. \u0000Kata kunci: banjir, permukiman, tingkat kerawanan","PeriodicalId":253388,"journal":{"name":"JURNAL BUDIDAYA PERTANIAN","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128836499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
