The Impact

The conversion of agricultural land  in Sumedang of  the  year  2005-2014 reached 317 hectares. The land generally converted  into housing, office buildings and public facilities. This study aims to conduct a comprenhensive  evaluation of the factors affecting changes in  land use, analyze the impact of the changes and develop management strategies. This research was conducted with a qualitative approach located in Sumedang District, West Java Province. Sampling was done by multistage random sampling. The first step is selection of the sample subdistricts purposively with consideration of subdistricts that convert of land use at most, they are: Sumedang Selatan, Jatinangor and Jatigede. The second step sample selection by simple random  to residents who do changes their agricultural land use. The data obtained from questionnaires, interviews,observations, study of documents and mass media. Working method is based on a modification of the stages of strategic planning for the company. Formulation of the strategy carried out through three phases: phase determination of the key internal and external factors, phase matching using the SWOT matrix, as well as the decision phase using QSPM matrix. The resulting strategy is implemented in a more technical work steps. The results showed the factors that affect farmers convert agricultural land is decreasing productivity of  the land, accretion of family members, the right of inheritance of land, high land prices, construction of public facilities and government policy. The most dominant factor affecting is different in each district. The impact of changes in land use in general is the opening of new agricultural land by cutting down forests, decline in rice productivity and the emergence of new unemployment and alteration or  loss of livelihood. From the SWOT analysis matrix, obtained three possible strategic options. First, a policy review of spatial and territories; second, to encourage farmers to maintain agricultural land by providing agricultural inputs and extension the use of organic materials to restore soil fertility and the third private land use change should be governed by strict licensing mechanism.

The Impact

Soil properties are strongly influenced by the composition of the surrounding vegetation. We investigated soil properties of three ecosystems; a coniferous forest, a deciduous forest and an agricultural grassland, to determine the impact of land use change on soil properties. Disturbances such as deforestation followed by cultivation can severely alter soil properties, including losses of soil carbon. We collected nine 40 cm cores from three ecosystem types on the Roebuck Farm, north of Perth Village, Ontario, Canada. Dominant species in each ecosystem included hemlock and white pine in the coniferous forest; sugar maple, birch and beech in the deciduous forest; grasses, legumes and herbs in the grassland. Soil pH varied little between the three ecosystems and over depth. Soils under grassland vegetation had the highest bulk density, especially near the surface. The forest sites showed higher cation exchange capacity and soil moisture than the grassland; these differences largely resulted from higher organic matter levels in the surface forest soils. Vertical distribution of organic matter varied greatly amongst the three ecosystems. In the forest, more of the organic matter was located near the surface, while in the grassland organic matter concentrations varied little with depth. The results suggest that changes in land cover and land use alters litter inputs and nutrient cycling rates, modifying soil physical and chemical properties. Our results further suggest that conversion of forest into agricultural land in this area can lead to a decline in soil carbon storage.

Trade Off

Background The discovery-dominance trade-off is the inverse relationship between the ability of a species to discover resources and the species’ dominance of those resources; a paradigm used to explain species coexistence in ant communities dependent on similar resources. However, factors such as stress (e.g., temperature) or disturbance (e.g., removal of biomass) associated with the change in land use, can modify this trade-off. Here, we aimed to determine the potential effects of land use change on dominance hierarchy, food preferences and on the discovery-dominance trade-off. Methods An experiment with baits was used to investigate the dominance hierarchies of ant communities in a temperate mountain habitat in central Mexico. We evaluated the dominance index (DI), food preferences and discovery-dominance trade-offs of ants inhabiting two types of vegetation: a native oak forest and agricultural land resulting from agricultural land use and grazing. Results The ant communities in both environments were comprised of three species of ants (Monomorium minimum, Myrmica mexicana, and Camponotus picipes pilosulus), four morphospecies (Pheidole sp.1 and Pheidole sp.2, Temnothorax sp. and Lasius sp.) and one genus (Formica spp.). All Formicidae showed values of intermediate to low DI, and this factor did not seem to be influenced by the change in land use. Ants in the modified vegetation (i.e., agricultural land) were found to be numerically greater. Overall, a higher number of visits were registered to the tuna bait, although the duration of foraging events to the honey baits was longer. However, foraging times were dependent on the species considered: the generalized Myrmicinae, M. minimum, the ant species with highest DI, foraged for longer periods of time in the agricultural land and on the tuna bait. Meanwhile, the cold-climate specialist Formica spp., with a lower DI, foraged for longer periods of time in the oak (although not significant) and on the honey bait. We found little evidence of the discovery-dominance trade-off; instead, we found considerable diversity in the strategies used by the different species to access resources. This range of strategies is well represented by the generalized Myrmicinae M. minimum, the cold-climate specialists Formica spp. and Temnothorax sp., and the rare species, as the cold climate specialist Lasius sp. (insinuators). Conclusions Our evaluation shows that transformation of the original habitat does not appear to affect the hierarchical dominance of the ant communities, but it does affect their food preferences. Species with higher DI values such as the generalized Myrmicinae are more skilled at resource acquisition in modified habitats. Our results suggest that change in land use promotes an increase in the diversity of foraging strategies used by different ant species. This diversity may contribute to resource partitioning which favors coexistence.

Akibat permintaan lada yang tinggi menyebabkan terjadinya masalah bagi petani Aceh dalam keterbatasan produksi lada. Salah satunya lahan pertanian dikonversikan menjadi non pertanian seperti perumahan, gedung dan pertokoan. Sehingga lahan pertanian menjadi berkurang dan menjadi masalah bagi petani lada sendiri dalam mengembangkan lada. Penyebab masalah lain juga yang akibat hama dan penyakit terutama penyakit layu, penyakit keriting daun serta penyakit busuk pangkal batang. Tujuan Penelitian untuk mengetahui faktor-faktor yang diperhatikan pada pengembangan lada, serta mengetahui strategi pengembangan lada yang tepat. Metode Penelitian yang digunakan adalah metode studi kasus. Teknik Pengumpulan data digunakan dengan pendekatan wawancara. Hasil analisis  menunjukkan faktor internal yang  mempengaruhi usaha pengembangan lada adalah bibit, pestisida, sumber daya alam, pupuk, dan sumber daya manusia. Sedangkan faktor eksternal yang mempengaruhinya adalah pemerintah, pasar, harga, pesaing, hama dan penyakit. Berdasarkan hasil analisis SWOT didapatkan nilai IFAS (Internal Strategic Factors Analysis Summary)  sebesar 1,756 dan EFAS (Eksternal Strategic Factors Analysis Summary)  sebesar 2,773 berada pada kuadran I , maka  strategi pengembangan yang cocok untuk strategi pengembangan lada adalah  strategi agresif  yang artinya usaha tersebut sangat dimungkinkan untuk terus berkembang, meningkatkan pertumbuhan dan meraih kemajuan secara maksimal, dimana strategi agresif ini merupakan kondisi yang sangat menguntungkan, peluang dan kekuatan begitu besar sehingga pelaku usaha bisa memanfaatkan peluang dan kekuatan yang ada secara maksimal.Strategy of pepper development (case study of indatu farmer group in blang panyang village sub-district estuary one, Lhokseumawe City) Abstract. Pepper is one of the most popular herbs from Aceh plantations. Especially pepper farmers in Aceh are now starting to pay attention to pepper to be developed with the aim of increasing income and welfare. In other words, Pepper became the most popular commodity in the world trade. Because various countries use this pepper as a spice cooking kitchen. On the other hand, due to the development of food business, the development of pharmaceutical industry, cosmetics using pepper as one of the raw materials, the increasing of world consumption, domestic consumption is increasing with the increase of pepper based food industry products. As a result of high pepper demand causes problems for Acehnese farmers in the limitations of pepper production. One of them agricultural land converted into non-agricultural such as housing, buildings and shops. So that agricultural land becomes reduced and become a problem for pepper farmers themselves in developing pepper. Other causes of problems are also caused by pests and diseases, especially wilt disease, leaf curling disease and stem rot disease. Research Objectives to determine the factors that are considered in the development of pepper, as well as to know the appropriate pepper development strategy. The research method used is case study method. Technique Data collection is used with interview approach. The results of the analysis show that the internal factors affecting pepper development are seeds, pesticide, natural resources, fertilizer and human resources. While on external factors that include government, markets,prices, competitors,pest and diseases. Based on the result of SWOT analysis, the value of IFAS (Internal Strategic Factors Analysis Summary) of 1.756 and EFAS (External Strategic Factors Analysis Summary) of 2.773 are in quadrant I, then a suitable development strategy for pepper development strategy is aggressive strategy which means the business is very possible To continue to grow, to increase growth and to achieve maximum progress, where aggressive strategy is a very favorable condition, opportunities and strength so large that business actors can take advantage of opportunities and strengths that exist maximally.

Abstrak  Pertumbuhan  penduduk dan dinamika pembangunan telah menggeser pemanfaatan lahan yang akhirnya menimbulkan kompleksitas permasalahan lahan yang semula berfungsi sebagai media bercocok tanam (pertanian), berangsur-angsur berubah menjadi multifungsi pemanfaatan. Berubahnya pemanfaatan lahan pertanian ke non pertanian dapat disebut juga sebagai alih fungsi lahan. Kabupaten Aceh Besar adalah salah satu kabupaten yang terus menghadapi permasalahan alih fungsi lahan, khususnya lahan sawah. Alih fungsi lahan ini mengakibatkan luas lahan sawah di Aceh Besar terus menurun. Lahan yang paling banyak mengalami alih fungsi lahan adalah jenis lahan sawah yang menjadi lahan non pertanian. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang menyebabkan terjadinya alih fungsi lahan sawah dan mengidentifikasi dampak sosial dan ekonomi yang dialami petani mantan pemilik lahan akibat alih fungsi lahan sawah menjadi lahan non pertanian. Berdasarkan hasil regresi secara parsial dari analisis regresi faktor harga jual, kebutuhan hidup dan kondisi lahan berpengaruh nyata terhadap konversi lahan sawah di  Kecamatan Baitussalam Kabupaten Aceh Besar. Bedasarkan hasil regresi secara serempak dari hasil regresi didapatkan bahwa harga jual, kebutuhan hidup dan kondisi lahan secara serempak mempengaruhi konversi lahan sawah di Kecamatan Baitussalam Kabupaten Aceh Besar. Berdasarkan isu dampak sosial sebagai akibat alih fungsi lahan di lihat dari keinginan kondisi lama, meningkatkan rasa kerjasama dan kekeluargaan, serta kemampuan memenuhi kebutuhan keluarga mendapatkan hasil yang positif dengan nilai ≥ 50%. Berdasarkan isu dampak ekonomi sebagai akibat alih fungsi lahan di lihat dari peningkatan pendapatan mendapatkan hasil yang positif dengan nilai ≥ 50%.Impact Of Paddy Fields Function  On Community Socio-Economic Conditions Of Baitussalam District, Aceh Besar RegencyAbstract  Population growth and the dynamics of development have shifted land use which eventually led to the complexity of the problem of land that used to function as a farming medium (agriculture), gradually becoming a multifunctional use. Changing the use of agricultural land to non-agriculture can also be referred to as land conversion. Aceh Besar District is one of the districts that continues to face the problem of land conversion, especially rice fields. The conversion of this land function has caused the area of paddy fields in Aceh Besar to continue to decline. The land that has experienced the most land use change is the type of rice field that becomes non-agricultural land. This study aims to identify the factors that cause the conversion of paddy fields and identify the social and economic impacts experienced by farmers former landowners due to the conversion of paddy fields to non-agricultural land. Based on the partial regression results from the regression analysis, the factors of selling price, life necessity and land conditions have a significant effect on the conversion of paddy fields in Baitussalam District, Aceh Besar District. Based on the simultaneous regression results from the regression results, it was found that the selling price, life needs and land conditions simultaneously affected the conversion of paddy fields in Baitussalam District, Aceh Besar District. Based on the issue of social impacts as a result of land use change seen from the desires of the old conditions, increasing the sense of cooperation and kinship, as well as the ability to meet family needs get positive results with a value of ≥ 50%. Based on the issue of economic impact as a result of the transfer of land functions, it can be seen from the increase in income that has a positive result with a value of ≥ 50%.
