Abstract

Untuk memenuhi kebutuhan pangan yang semakin tinggi maka produktivitas usaha pertanian perlu ditingkatkan. Salah satu yang penting dilakukan untuk mendorong peningkatan produksi adalah menyediakan informasi karakteristik hara lahan kepada petani secara akurat, tepat dan mudah. Jika petani memahami kondisi area yang ditanami maka mereka dapat menentukan teknik budidaya yang sesuai. Dengan semakin banyaknya petani yang menggunakan smartphone, maka penting adanya sistem informasi geografis yang berjalan di perangkat mobile (mobile GIS) yang dapat memberikan informasi kandungan hara lahan spesifik lokasi. Penelitian ini akan mengembangkan prototipe mobile GIS untuk perangkat berbasis Android. Diharapkan dengan aplikasi ini petani dapat menentukan lokasi yang menjadi perhatian melalui menu pencarian lokasi atau menggunakan GPS di perangkat. Setelah lokasi ditentukan, sistem akan memperlihatkan peta dan tabel kandungan hara di wilayah tersebut. Aplikasi ini menghasilkan fitur utama berupa peta yang menampilkan kandungan nitrogen, phospor dan kalium serta kondisi keasaman tanah (pH) di lokasi tertentu di Jawa Barat. Sistem yang dikembangkan dilengkapi dengan petunjuk penggunaan fitur dan glosarium untuk membantu pengguna dalam menggunakan aplikasi dan memahami istilah penting yang terdapat di dalam aplikasi. Prototipe yang dihasilkan merupakan produk awal yang bersifat umum dan merupakan bagian dari usaha untuk mencari bentuk interaksi antarmuka yang tepat dan arsitektur sistem yang adaptif.

Abstract

The availability of water plays an important role in plant growth. However, water availability depends on the climate and irrigation channels; therefore, there is little water available for plants during the dry season. Bacteria found in soil can produce exopolysaccharides to survive under extreme land conditions, namely, during drought conditions. The research objectives were to (1) isolate and select bacteria originating from dry land for use on chili plants and (2) determine the effect of water supply frequency and select soil bacteria on chili plants. The experiment consisted of two stages. (1) Bacterial selection and characteristics, which included exopolysaccharide bacteria selection on specific ATCC No. media. 14; pathogenicity test (hypersensitivity and hemolysis); characterization and biochemical testing including pH, temperature, salinity, oxidation, and catalase; bacterial functional tests (P and K solvents and nitrogen-fixing); and (2) tests of chili plants in the greenhouse. The treatment consisted of two factors: (a) application of selected bacteria, (b) frequency of water application (every 1, 2, 3, and 5 days), and (3) molecular identification of selected bacteria. The results showed that the best growth of chili plants was obtained by treating them with bacteria and watering them every other day. Molecular identification demonstrated that the selected bacteria was Sphingomonas yunannensis, which can grow under environmental conditions affected by drought. Keywords: exopolysaccharides, drought, Sphingomonas yunannensis, chili plants

Abstract

Kabupaten Bandung memiliki ketinggian tempat antara 675 mdpl – 2,100 mdpl dengan suhu udara berkisar 14oC sampai dengan 30oC. Perbedaan ketinggian tempat dapat menimbulkan perbedaan iklim dan cuaca sehingga dapat mempengaruhi transformasi hara dan populasi mikrob di dalam tanah. Penelitian ini bertujuan untuk mengetahui korelasi sifat biologi dan kimia tanah, serta kaitannya antara sifat kimia dan fisika tanah pada berbagai ketinggian tempat di Bandung, Jawa barat. Pengambilan sampel tanah menggunakan metode Purposive Random Sampling dengan 5 kali ulangan. Sampel tanah terganggu diambil pada kedalaman 0-20 cm sebanyak ±1 kg, sedangkan contoh tanah utuh diambil menggunakan ring sampler. Pengambilan sampel tanah meliputi empat ketinggian tempat yaitu ketinggian 600 mdpl penggunaan lahan tanaman kol, ketinggian 1000 dan 1200 mdpl penggunaan lahan tanaman selada, serta ketinggian 1400 mdpl penggunaan lahan perkebunan kopi. Hasil analisis menunjukkan bahwa pada ketinggian 1000 mdpl populasi bakteri pelarut fosfat (BPF) dapat tumbuh optimum sebesar 93.6 x 103 CFU g-1 dengan pH tanah agak masam, P-Total sangat tinggi, dan P-Tersedia sedang. Populasi fungi dapat tumbuh optimum sampai ketinggian 1200 mdpl. Total populasi fungi berkorelasi tinggi dengan unsur hara P-Total dan N-Total di dalam tanah. Respirasi tanah berkorelasi positif dengan semua parameter yang berhubungan dengan sifat kimia tanah. Nilai bobot isi terendah pada ketinggian 1200 mdpl bersesuaian dengan nilai C-organik dan porositas tertinggi pada ketinggian tersebut.

Abstract

Two field measurement of infiltration rate methods had been performed on Latosol (Oxic dystrudept) Dramaga Bogor in order to investigate the opportunity to generate different result due to the different of hydraulic head applied and the different way of water was supplied. They were constant head and falling head methods. Falling head method was done in two different ways, namely within a certain time interval and within a certain water level interval. Hydraulic head used during measurement were of 10 cm, 15 cm, and 20 cm. The falling head and constant head method, clearly, generated different minimum infiltration rate values The falling head method measured on a fixed time interval generated almost the same values of minimum infiltration rate, respectively of 4.8 cm hour -1, 5.5 cm hour -1, and 4.8 cm hour -1 at 10 cm, 15 cm, and 20 cm hydraulic head. The falling head method based on bulk water level interval at 10 cm, 15 cm, and 20 cm generated minimum infiltration rate values respectively of 13.2 cm/hour, 12.8 cm/hour, and 18.8 cm/hour. The constant head method at 10 cm, 15 cm, and 20 cm hydraulic head generated minimum infiltration rate values respectively of 11.0 cm/hour, 18.5 cm/hour, and 19.0 cm/hour. The values were higher than of the fixed time interval based falling head method. Infiltration field measurement using the falling head method either based on time interval or water level interval did not show an increasing trend of minimum infiltration rate values due to the increase of hydraulic head. However, the infiltration field measurement using constant head showed an increasing trend of the minimum infiltration rate values due to the increase of hydraulic head.

Abstract

Currently, water resources management is still focused on on-site water resources infrastructure to achieve optimal water utilization, with almost never considered land management in which water resources are produced naturally. The research aim is to study the water balance in the Upper Cisadane Sub-Watershed, and to simulate a land use plan and development of water resource infrastructure to fulfill the need for water in the Upper Cisadane Sub-Watershed using the SWAT (Soil and Water Assessment Tool) model. Existing water availability was calculated using stream discharge data from River Flow Measurement Station Empang, whereas water demand has been analyzed for domestic, industries, agriculture, fisheries, and animal husbandry. Totally, water availability in the Upper Cisadane Sub-Watershed was ± 222.9 MCM (Million Cubic Meters) year-1, which was higher than the demand for water of as much as ± 209.8 MCM year-1 and resulted in a water surplus of ± 13.1 MCM year-1. However, water availability was not evenly distributed throughout the year, and there was always a water deficit in the dry season. To overcome drought during the dry season, five simulations of land use management and construction of water retention infrastructure were carried out using the SWAT model. The water deficit in the Upper Cisadane SubWatershed will be overcome by the consistent application of the spatial plan of West Java Province, reforestation of converted forest areas, applied agroforestry in agricultural land, and development of a reservoir with a storage capacity of 30 MCM.

Abstract

The research is aimed to analyze leachate, surface water and ground water characteristics around Galuga landfill site, Bogor District. Water samples had been taken in dry season of 2014 and in the end of rainy season of 2015 from several sites in areas around Galuga landfills which included leachate water, surface water, and ground water. Leachate, surface water and ground water had temperature and pH in normal ranges; whereas nitrate and Pb contents were high to very high levels, especially in site adjacent to waste piles. The concentrations decreased in line with increasing distance from waste piles. Higher content of nitrate in leachate occurred in dry season, but in well water it was found in rainy season. Meanwhile, Pb content in well water were high, both in dry and rainy seasons. Concentrations of nitrate and Pb in leachate water were higher than wastewater quality standard, so that the leachate water were not safe to be discharged directly to natural water body. The high content of nitrate and Pb caused the well water unsuitable to be consumed without water treatment processing.
