River is an important component of the environment can not be separated from agricultural fields and plantations. Rivers play an important role in irrigation of agricultural crops and plantation society. Baboons current river conditions are thought to have experienced a decline in water quality due to various human activities such as residential, agricultural and industrial. Water quality degradation caused by agriculture and plantations because in order to increase agricultural production and farming, both quantitative and qualitative, have supported the use of pesticides. In its implementation, the use of these pesticides often do not follow the rules, which tend to be in high quantity in order to get quick results in halting the growth of pests and diseases. Pesticides used on farm fields, most or even all will fall into the water and polluting the waters. This study aims to analyze the water quality of the river baboons by river water quality standards according to Government Regulation No. 82 of 2001, as well as analyzing the pollution load entering the river Pesticides baboons derived from agricultural activities. The results showed BOD and COD at some point has exceeded the quality standard required. The index value of the upstream to downstream pollution tends to increase, exceeding the quality standards specified in the criteria unyuk river water quality standard Class II. River baboons have contained residues of endosulfan insecticide in concentrations ranging from 0.6 to 3.0 ug / L.

Tomat merupakan salah satu sayuran utama yang dikembangkan secara luas. Dewasa ini beberapa tanaman termasuk tomat, mengalami stagnansi, dimana rata-rata produktivitasnya per hetar sulit sekali dikembangkan dan ditingkatkan. Penerapan system pertanian yang mengutamakan penggunaan pestisida dan pupuk kima masih sangat melekat pada model pertanian kita, padahal peningkatan produksi dari penggunaan bahan-bahan tersebut hanya bersifat sementara, sedangkan dampak negatifnya sangat besar karena menyebabkan kerusakan pada sifat fisik, kimia dan biologi tanah. Dewasa ini telah banyak diketahui secara parsial tentang pengendalian organism pengganggu tanaman menggunakan biopestisida berupa pestisida nabati dan agensia hayati, sedangkan pemupukan menggunakan pupuk hayati antara lain pemanfaatan mikroorganisme efektif, baik berasal dari daerah subtropis maupun tropis, yang didalamnya mengandung beberapa macam mikroorganisme antara lain; bakteri selulotik, jamur selulotik, bakteri fotosintetik, bakteri asam laktat, bakteri pelarut fosfat, dll. Kurangnya kajian kambonasi antara penggunaan biopestisida dengan pupuk hayati dalam mendukung penggelolaan tanaman tomat secara terpadu merupakan alasan logis berkembangnya penelitian ini. Dan akhirnya didapatkan kombinasi komponenen / variasi keonsentrasi penggunaan biopestisida dan pupuk hayati untuk pengelolaan tanaman tomat secara terpadu. Dari pengamatan yang dilakukan diketahui bahwa Penggunaan jamur Gliocladium sp dengan dosis 10 dan 20 cc/liter air dapat menekan serangan penyakit Fusarium sp pada tanaman tomat sebesar 16,32 ± 25,63% menyebbkan tajukyng lebih lebar dan produksi tomat yang paling baik

Population growth will be followed by the fulfillment of a residence or settlement so that it will trigger a land conversion. Land conversion or land conversion is defined as a change in the function of part or all of the land area from its original function (as planned) to other functions that have negative impacts (problems) on the environment and the potential of the land itself. According to BPS (2001) in a period of 7 years (1993-2000) there was a reduction in Indonesian agricultural land by 710,000 ha or 56.167 ha per year. As the population in Indonesia increases, it is followed by a decrease in the area of agricultural land due to the process of land conversion to meet residential needs. Land conversion that is carried out directly or indirectly, can be temporary or permanent, can be in the form of gradual conversion with a sporadic pattern, systematic conversion with an “enclave” pattern, land conversion in response to population growth, conversion caused by social problems, conversion without burden and Agricultural adaptation conversion Land conversion is influenced by external factors including economic, socio-cultural, increasing population and regulations, while internal factors such as less productive land and economic pressure from farmers. Conversion of agricultural land has a positive impact in the form of increased investment in the non-agricultural sector but has a negative impact on threatening national food security and decreasing environmental quality.
