The Impact

Lahan merupakan salah satu sumber daya agraria yang sangat penting bagi petani dikarenakan lahan merupakan salah satu sumber untuk bertahan hidup. Sesuai dengan Undang-Undang Dasar Nomor 41 Tahun 2009 tentang Perlindungan Lahan Pertanian Pangan Berkelanjutan. Pembangunan yang terjadi di Indonesia semakin masif, menimbulkan konversi lahan bersifat permanen ketika lahan sawah beririgasi berubah menjadi kawasan pemukiman atau industri. Konversi lahan yang terjadi menyebabkan hilangnya beberapa atau seluruh modal nafkah yang ada. Perubahan modal nafkah ini akan mengakibatkan perubahan strategi nafkah petani. Penelitian ini bertujuan untuk menganalisis dampak konversi lahan terhadap strategi nafkah dan pengaruh pemanfaatan  modal nafkah  terhadap strategi nafkah rumah tangga. Lokasi penelitian ini yaitu Desa Pasirgaok, Kecamatan Rancabungur, Kabupaten Bogor. Metode yang digunakan untuk menggali fakta, data, dan informasi dalam penelitian adalah pendekatan kuantitatif melalui metode survei dengan kuesioner yang didukung oleh data kualitatif melalui wawancara dan studi literatur hingga diperoleh hasil bahwa dampak konversi lahan mempengaruhi modal dan strategi nafkah.Kata Kunci: buruh tani, konversi lahan, modal nafkah, strategi nafkah=====ABSTRACTLand is one of the most important agrarian resources for farmers because land is one source of livelihood survival. According to Constitution Number 41 Year 2009 on concerning The Protection of Sustainable Food Agriculture. The development that is taking place in Indonesia is increasingly massive leading to permanent land conversion when technical irrigated rice fields change into residential or industrial areas. The land conversion that occurs causes a loss of some or all existing livelihood asset. This change in livelihood asset will result in a change in farmers livelihood strategies. This study aims to analyze the influence of the impact of land conversion towards livelihood strategies and the influence of the utilization of livelihood asset towards the livelihood strategies households. The location of this research is Pasirgaok Village, Rancabungur District, Bogor Regency. The method used to extract facts, data, and information in the research is the quantitative approach through survey method with questionnaires supported by qualitative data through interview and literature study until it is obtained that the impact of land conversion towards landless farmer household’s assets and livelihood strategies.Keywords: land conversion, landless farmer, livelihood asset, livelihood strategies

Spectral Responses

The state of Rio Grande do Sul is one of the greatest Brazilian soybean producers, which justifies the use of remote sensing techniques for monitoring areas occupied by this crop. The purpose of this work was to characterize throughout the crop cycle the variability of spectral responses of soybean leaflets, subjected to different conditions of soil tillage and water supply. The experiment was carried out in a 0.5 ha area, located in Eldorado do Sul, Rio Grande do Sul State, southern Brazil, in two systems of soil tillage (no-tillage and conventional tillage) and two levels of water supply (irrigated and non-irrigated). The cultivar Fepagro RS-10 was sown in a row spacing of 0.40 m and in a population of 400,000 plants per hectare. An integrating sphere of a spectroradiometer LI-COR, model LI-1800 was used for measuring the absorbance, reflectance, transmittance on soybean leaflets. The results showed that the pattern of the incident radiation partitioning in the reflectance, transmittance and absorbance components is influenced by the crop phenological stage and by the tillage system. Despite this, there is stability on the reflectance of soybean leaflets in the red and infrared portions of the electromagnetic spectrum, throughout the crop cycle. The inversely proportional relation between absorbance and reflectance of soybean leaflets revealed viability on the reflectance data, in monitoring of agricultural crops.

Paddy Crop

Padalarang pulp and paper mill, a soda pulp and paper mill without chemical recovery, located near Bandung, Indonesia, discharges untreated effluent mixed with domestic waste water into surrounding rice fields. For more than 60 years, paddy has been harvested 3 times a year. An in-depth study to characterize the effluent, the soil and the biomass production was conducted to define the evidence. A field study using four experimental plots indicated that soil irrigated with effluent had a higher concentration of potassium, calcium, sodium ions and greater cation exchange capacity than near-by soil. Analysis of well water showed that the effluent had no effect on the ground water. A reduction of suspended solids and BOD occurred in the effluent while flowing through rice fields. The yields of paddy demonstrated significant positive effect of effluent either in dry or in rainy season, while zeolites as soil amendment did not give significant effect to the already high paddy crop yield.
