ABSTRACTResidue of Pesticides on Horticultural Crops (Case Study in Cihanjuang Rahayu Village, Parongpong District, West Bandung Regency)The purpose of this study was to investigate the type of residual concentrate of chlorpyrifos pesticides accumulated in horticultural crops, the impact of pesticide residues to the public health and daily intake assumption. This study used a quantitative approach to survey methods to know in depth about pesticide residues on horticultural crops where the data source consisted of primary data obtained from interviews and the results of chemical analysis and secondary data collected directly from some sources. In several types of insecticides used by farmers in Cihanjuang Rahayu village, there are kind of insecticides that did not recommended to control pests on broccoli. Based on the analysis of pesticide residues, residue results were obtained from four broccoli samples with 10%, 20%, 60% and 80% greater than the maximum residue limit. This suggests that the four samples tested contain harmful residues exceeding the maximum limit of 2 ppm residue. Health effects of pesticides on farmers included nausea, vomiting, dizziness and itching of the skin. The calculating results of intake assumption on the risk of health obtained the result of 1,505 g/day with the highest value of 4,014 g/day and the lowest risk was the amount of intake of 423 g/day. From the results of these calculations, it can be seen that the amount of consumption of vegetables and horticulture was having average risk to farmers as much as 1,505 g/day.Keywords: Residue, Pesticides, Horticulture, BroccoliABSTRAKTujuan penelitian ini yaitu untuk mengetahui jenis konsentrat residu pestisida klorpirifos yang terakumulasi pada tanaman hortikultura, dampak residu pestisida bagi masyarakat dan asumsi asupan beresiko kesehatan per hari.

ABSTRACTAnalyse of soil chemical properties in the encriment of oil palm production on sandy soil at Selangkun oli palm plantationSoil is one of basic components in the development of oil palm plantation. Limitation of land causes many companies expand their areas to the sub-optimal land, such as sandy soil. This research was aimed to analyzed chemical soil properties and its relation with bunch number and bunch weight in oil palm plantation, Arut Selatan sub-district, Central Kalimantan. Survey was made in sample points that were determined based on grid system, and each sample was taken in the depth of 30 cm. This research was descriptive and used double regression equation with backward-stepwise method. Several parameters have been analyzed, such as pH, organic carbon, CEC, total N, total P, P-availability, K, Ca, Mg, Cu, Zn, Mn, and B. The result showed that the pH was categorized acid, macro nutrients were medium to very low, except total P and P-availability, while micro nutrients were enough, except boron which had very high amount. Furthermore, statistical analysis showed that some chemical properties, such as total N, CEC, and exchangeable Al were parameters which influenced production of bunch number per oil palm plant.Keywords: Oil palm, Soil nutrient, Sandy soilABSTRAKTanah merupakan salah satu komponen dasar dalam pembangunan perkebunan kelapa sawit.

ABSTRACTParaquat adsorption and Soil Properties on Three Soil Subgroups Due to Ameliorant ApplicationParaquat (Bipyridylium biclorida) is known as a highly toxic herbicide and quite widely used by the farmers. The material can be adsorbed by soil colloids and can contaminate soil and water. The study aimed to determine the ability of three of soil subgroups of different orders (Typic Hapludult, Typic Hapludand,and Chromic Endoaquert) to adsorb paraquat, finding the best kind of ameliorant in reducing residues, and studying its effect on corn crops. The study was conducted in two stages, namely (1) to test the maximum adsorption capacity of paraquat on the three of soil subgroups based on the Langmuir equation, and (ii) to study the influence of the type and ameliorant dose on three soil subgroups saturated with paraquat. Methods used were completely randomized design experiment nested models. The results of laboratory experiments showed that the topsoil layer of Typic Hapludands was dominated by halloysite and little amorphous clay minerals. While predominantly Typic Hapludult was dominated by kaolinite and little smectite. Chromic Endoaquert contained little kaolinite and was dominated by smectite. Saturation points in all three soil subgroups were 1.883 cmol kg-1, 20.833 cmol kg-1, and 9.346 cmol kg-1 paraquat, respectively. The type and dose of each ameliorant signifancty affected paraquat adsorption capacity, soil pH and electrical conductivity in all three soil subgroups, except for paraquat adsorption capacity and pH which were not affected in Typic Hapludults. The highest dose of activated charcoal adsorbed paraquat markedly higher compared with other treatments on Typic Hapludands, whereas Chromic Endoaquerts activated charcoal had the same effect with the zeolite, but higher than straw and control. Furthermore, on Typic Hapludults ameliorant did not significantly affect the adsorption capacity of paraquat, except when compared with controls.Keywords: Paraquat, soil subgroups, adsorption, ameliorant.ABSTRAKParaquat (Bipyridylium biclorida) dikenal sebagai herbisida yang sangat toksik dan pengunaannya cukup luas di kalangan petani. Bahan ini dapat diadsorpsi oleh koloid tanah dan dapat mencemari tanah dan air. Penelitian ini bertujuan untuk mengetahui kemampuan tiga subgrup tanah berlainan ordo (Hapludult Tipik, Hapludand Tipik, dan Endoequert Kromik) mengadsorpsi paraquat, menemukan jenis amelioran yang paling baik dalam menekan residu paraquat, serta mempelajari pengaruhnya terhadap hasil tanaman jagung. Penelitian dilakukan dalam dua tahap, yaitu (1) Uji kapasitas adsorpsi maksimum paraquat pada tiga subgrup tanah berdasarkan persamaan Langmuir, dan (2) pengaruh jenis dan dosis amelioran pada tiga subgrup tanah terjenuhi paraquat terhadap adsorpsi, pH, dan daya hantar listrik. Metode yang digunakan Rancangan Acak Lengkap model percobaan Tersarang. Hasil percobaan di laboratorium menunjukkan titik jenuh paraquat pada ketiga subgrup tanah tersebut masing-masing sebesar 1,883 cmol kg-1, 20,833 cmol kg-1, dan 9,346 cmol kg-1. Jenis dan dosis amelioran masing-masing berpengaruh nyata terhadap kapasitas adsorpsi paraquat, pH tanah dan daya hantar listrik pada ketiga subgrup tanah, kecuali kapasitas adsorpsi paraquat dan pH tidak dipengaruhi pada Hapludult Tipik. Arang aktif dosis 20% media tanah mampu mengadsorpsi paraquat nyata lebih tinggi dibandingkan dengan perlakuan lainnya pada Hapludand Tipik, sedangkan pada Endoaquert Kromik, arang aktif memiliki pengaruh yang sama dengan zeolit, tetapi lebih tinggi dari jerami dan kontrol.
