Abstract

Aluminum Detoxification by Humic Substance Extracted from Compost of Organic Wastes (S Winarso, E Handayanto and A Taufiq):  Humic substance could control the activity of metal as well as exchangeable aluminum (Alexch) on acid soil. The humic substance extracted from compost of agricultural waste is rarely conducted. The objective of research was to evaluate the effect of humic substance concentration and sources to pH and Al suspension. The research had been conducted in the Soil Laboratory of Agricultural Faculty of Jember University from April to July 2009. The humic substance used in these researches was extracted from compost of rice straw (RS), soybean straw (SS), cassava starch solid waste (CSSW), and empty bunch of oil palm tree (EBOPT). The humic substance concentration treatments were 0, 10, 20, 30, 40, 50, 75, 100, 150, 200, 250, and 300 ppm. Result of the analysis showed that characteristic of humic substance was difference depending on the source material used. The humic substance extracted from SS contain total base cations (K, Na, Ca, Mg) higher (1.17%) compared with CSSW (1.07%), OPT  (0.87%), and RS (0.69%). While the humic substances extracted from RS contain total organic acid (Acetic, Fumeric, cetoglutamic, Sucsinic, Propionic, Butiric, Ocsalic, and sitric acid) higher (157 ppm) compared with EBOPT (129 ppm), SS (115%), and CSSW (108%). Among these organic acids, acetic acid was highest concentration (> 34.51% of total acid). The addition of humic substance increased pH and decreased aluminum concentration of the suspension. The higher pH increment and Al concentration reduction took placed in the suspension treated with humic substance from SS compost. The correlation between decreasing Al concentration with humic substance concentration which explained chelation was higher (r = 0.97) than decreasing Al concentration with increasing pH which explained precipitation (r = 0.93). Based on these research results, it can be concluded that humic substance extracted from agricultural waste have a good prospect as a soil ameliorant to increase soil pH, detoxify soil aluminum, and increase soil P availability on acid soil.

Abstract

Effect of Humic Compounds and CaCO3 Combination on Aluminium and Phosphate of Typic Paleudult Kentrong Banten (S. Winarso, E. Handayanto, Syekhfani and D. Sulistyanto): Decomposition of organic matter releases humic compounds, that can chelate metals include Al in acidic soils. This chelation of Al is important for decreasing of Al activity and P fixation in acidic soils. This study was aimed to test the effect of humic compounds extracted from rice-straw compost and CaCO3 combination on aluminium activity and phosphate (available P) on an Ultisol (Typic Paleudult) collected from Kentrong Banten.  A laboratory study was conducted by series consentration of CaCO3 (0, 500, 1.000, 2.000, dan 3.000 ppm) in 8 grams of acidic soil. The acidic soil had previously been subjected to continuously addition of humic compounds and none. Then, these mix of soil and CaCO3 were added 40 ml contained 5.000 ppm humic compounds to obtain 1:5 soil:suspension ratio and  control was made by using aquadest. They were shaked for 2 hours every day and pH was measured. At 11st days incubation  Alexch (N KCl) and soluble of P (PB and PC) were measured.  The results  showed that liming or addition of CaCO3 to the acidic soils decreased Alexch (precipitated to be Al(OH)3) linearly with formula y = -0.778x + 6.108; y = Alexch (Cmol kg-1), x = CaCO3 (M); R² = 0,916. Combination addition of humic compounds and CaCO3 was able to increase pH and Alexch up to not detected. The increased of P-soluble or desorption P untill 384% took place at addition of 0.0016 M CaCO3 and 5000 ppm humic compounds. More desorption of P was observed if the acidic soils has previously been subjected to continuously addition of humic compounds, such us the increased of soluble P up to 739% at addition of CaCO3 0.0008 M.

Abstract

The community service activities carried out aim to foster an entrepreneurial spirit among households as an effort to improve the economy of families in the Gading Kasri sub-district. In addition, it also aims to encourage the surrounding community to be aware of maintaining environmental cleanliness and health, as well as the need for proper waste management. The community service methods included counseling, discussions, question and answer sessions, and hands-on practice in processing used items into items with added economic value. The results of this activity, which was attended by 15 representatives of PKK members, are expected to contribute to improving the economy of PKK mothers, to share knowledge, and to encourage the community to develop their resources in a sustainable manner to improve the family economy. This effort to recycle used items, specifically plastic waste, is intended to motivate the community to improve their abilities and skills and to work to bring benefits to themselves and the surrounding community by producing recycled plastic products such as flower vases, plastic flowers, wall decorations, and others.
