Abstract

The high content of NaCl in soil may lead to nutrient imbalance and inhibit the Nitrogen uptake by plants. Azolla pinnata can be used as an organic ameliorant to help plant roots in absorbing nutrients and enhancing the number of available N for plants. The aims of this research were to ascertain whether Azolla pinnata as organic ameliorant gave the significant difference on the enhancement of N content of soil, pH of soil, and dry weight of rice plant on various salinity level of soil and also to find out if Azolla pinnata can suppress salinity stress at certain salinity. The experiment was conducted at the Greenhouse of Faculty of Agriculture Universitas Padjadjaran, Jatinangor and also at the Laboratory of Soil Fertility and Plant Nutrion, Departement of Soil Science and Land Resources on November 2016 until March 2017. The experimental design used was randomized block design with 8 treatments and 4 replications. The treatments consist of without the organic ameliorant Azolla pinnata, and with the application of Azolla pinnata on salinity level 0, 2, 4, 6 mmhos cm-1. The results showed that the application of NaCl and Azolla pinnata gave the significant difference on soil pH, and dry weight of plant. The application of Azolla pinnata is not able yet to suppress the rice symptom of salinity stress at 2, 4, and 6 mmhos cm-1 on the enhancement of dry weight of plant. The application of Azolla at salinity 6 mmhos cm-1 was equivalent with salinity 2 mmhos cm-1 in producing dry weight of plant.

Abstract

Pada tahun 2004 di DAS Cimanuk Hulu telah diperkirakan mempunyai lahan kritis seluas 40.876 ha, namun hingga kini belum diketahui bagaimana penanganan terhadap fenomena tersebut. Sementara itu kejadian cuaca ekstrim di wilayah ini pada tanggal 20 September 2016 yang melahirkan bencana banjir bandang di kota Garut dapat dijadikan sebagai indikator tentang masih belum tertanganinya secara baik lahan kritis yang ada. Untuk itu perlu adanya upaya untuk menangani masalah tersebut, salah satunya dengan upaya deforestasi melalui agroforestri. Metode kegiatan pengabdian kepada masyarakat di Desa Cilampuyang Kecamatan Malangbong  ini berupa sosialisasi, penyuluhan, dan penanaman pohon. Penyuluhan dan diskusi dilaksanakan sebanyak dua kali bertempat di aula BPDASHL Cimanuk desa Cilampuyang. Kegiatan penanaman dilaksanakan setelah acara sosialisasi untuk memberikan ketrampilan secara teknis mengenai sistem agroforestry.

Abstract

Pada sistem hidroponik, pemberian pupuk anorganik dan pupuk hayati dilakukan untuk meningkatkan hasil tanaman karena pupuk anorganik menyediakan unsur hara dan pupuk hayati menghasilkan fitohormon yang meningkatkan pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati yang dikombinasikan dengan pupuk anorganik terhadap populasi bakteri pelarut fosfat, kandungan fosfat (P) dan hasil tanaman tomat. Penelitian ini dilakukan menggunakan rancangan acak kelompok (RAK) dengan 7 perlakuan kombinasi pupuk anorganik (konsentrasi 100%, 75%, dan 50%), pupuk hayati (konsentrasi 100%, 75%, 50%, dan 25%) 4 ulangan. Data yang diperoleh dianalisis secara statistik untuk melihat pengaruh perlakuan. Hasil percobaan menunjukkan bahwa kombinasi pupuk anorganik dan pupuk hayati menunjukkan hasil yang tidak berbeda nyata terhadap populasi bakteri pelarut fosfat, kandungan P, dan hasil tanaman tomat pada sistem hidroponik.

Abstract

Land use change has long been a problem in West Java, especially in Bandung district (Kabupaten Bandung), a hinterland and buffer area for the Bandung Metropolitan and one of the major crop district in West Java province.  Land use conversion caused the decrease of soil productivity and land availability for agricultural activity especially for food crops, the land reduction is unable to compensate the need of food availability.The research in this study has been done by using descriptive and comparative survey method to study land characteristic and status of land availability in Kabupaten Bandung and its contribution food crop development. The results showed that soil fertility status in Bandung district varies from very low to high. Soil pH conditions ranged from acid to neutral. The actual availability of land for food crops currently stands at 52,790 hectares, with paddy fields as current land use. Availability of potential land for food crops are 64,970 hectares with the current type of land use in the form of bushes and plantations.  Keywords: characteristics, availability, land use conversion, land, district Bandung

Abstract

This research was conducted to find out the effect of various slope classes and land use types on porosity, permeability and soil's aggregate stability index. The research was carried out from June up to December 2009 in Upper Cikapundung Sub Watershed which area was located in West Bandung Regency and Subang Regency, West Java. The method used in this research was explorative survey method. Sampling technique which used based on purposive stratified sampling method. Soil sampling was carried onto three various slope classes in three various land uses, which consist of: 8- 15% slope classes in pine forest, 8-15% slope classes in secondary forest, 8-15% slope classes in tea plantation, 15-30% slope classes in pine forest, 15-30% slope classes in secondary forest, 15-30% slope classes in tea plantation, 30-45% slope classes in pine forest, 30-45% slope classes in secondary forest and 30-45% slope classes in tea plantation. The result of this research showed that highest soil total porosity achieved in 8-15% slope classes in secondary forest, 8-15% slope classes in pine forest, 15-30% slope classes in all land use and 30-45% slope classes in all land use. Highest permeability achieved in 8-15% slope classes in all land use, 15-30% slope classes in tea plantation, 15-30% slope classes in pine forest and 30-45% slope classes in tea plantation. Soil index aggregate stability achieved in 8-30% slope classes in secondary forest, 8-30% slope classes in tea plantation and 30- 45% slope classes in all land use

Abstract

Penggunaan citra satelit Landsat TM telah banyak digunakan dalam bidang pertanian, terutama dalam hal penetapan atau identifikasi tutupan permukaan lahan seperti vegetasi, penggunaan lahan, kemiringan lereng, genangan air dan sungai, serta tutupan lainnya.  Studi ini bertujuan untuk mengetahui sejauh mana citra satelit Landsat TM dapat mengiden­tifikasi kelembaban dan tekstur tanah serta analisis kesesuaian lahan tanaman kina (Chinchona spp.) pada Sub-DAS Cikapundung Hulu di Kabupaten Bandung Jawa Barat dengan ketinggian tempat  1000-1500 m di atas permukaan laut. Metode yang digunakan dalam pene­litian ini adalah analisis deskriptif melalui interpretasi citra dengan membuat citra Normalized Difference Soil Index (NDSI), citra transformasi model Tasseled Cap: Wetness Index, survey lapangan dan analisis laboratorium. Hasil studi menunjukkan bahwa interpretasi citra satelit Landsat-TM dengan menggunakan pendugaan citra transformasi, dapat mengiden­tifikasi kelembaban tanah dengan tingkat akurasi 57,14 % dan untuk tekstur tanah sebesar 42,85 %. Karakteristik lahan pada Sub-DAS Cikapundung Hulu dikategorikan cukup sesuai (S2) untuk pengembangan tanaman kina dengan luasan area sebesar 68,69 ha.

Abstract

Kebijakan Otonomi Daerah dan Desentralisasi di Indonesia, membawa nuansa dan paradigma baru dalam pengembangan daerah. Metode perencanaan bottom up (dari bawah/masyarakat) adalah suatu usaha untuk meningkatkan partisipasi dari semua pihak (stake holder) sesuai dengan karakteristik daerahnya. Aspirasi dan informasi daerah yang diperoleh melalui analisis multi-faceted, wawancara, kuesioner, dan informasi lainnya, memunculkan Kabupaten Aceh Besar sebagai salah satu lokasi penelitian yang mempunyai potensi besar di bidang pertanian di Provinsi Nanggroe Aceh Darussalam. Hasil analisis menunjukkan bahwa ada tiga kecamatan di Aceh Besar yang dapat dikembangkan menjadi wilayah agropolitan. Kecamatan Indrapuri memiliki potensi paling besar untuk pengembangan kawasan agropolitan ini, karena memiliki persyaratan paling lengkap untuk kebutuhan tersebut. Pengelompokkan zona-zona pengembangan dan komoditas dari hasil analisis, menggunakan metode zona agroekologi, adalah : Zona I untuk kehutanan sekitar 81.465 ha (27, 39%), Zona II untuk perkebunan seluas 44.365 ha (14,92%), Zona III untuk keperluan agroforestri sekitar 65.232 ha (21,93%), Zona IV untuk tanaman pangan sebesar 56.350 ha (18,95%) dan Zona VI untuk kawasan mangrove seluas 50.100 ha (16,85%).Kata kunci: perencanaan wilayah, wilayah agropolitan, Kabupaten Aceh Besar.
