Kelas kerapatan kawasan hutan lindung Pantai Utara Kabupaten Banyuasin dibagi menjadi tiga kelas yaitu kelas kerapatan jarang, kelas kerapatan sedang dan kelas kerapatan lebat. Tahun 2014 kerapatan jarang terdistribusi merata di wilayah kawasan hutan lindung, dan kerapatan vegetasi lebat jumlahnya sangat sedikit. Faktor yang menyebabkan perubahan indeks kerapatan adalah adanya aktivitas manusia seperti penebangan pohon yang semakin sering dilakukan, konversi hutan primer dan sekunder menjadi pemukiman, perkebunan, sawah dan lain-lain.Perubahan tutupan lahan kawasan hutan primer tahun 1978-2014 dari hasil analisis data pada citra Landsat ditemukan perubahan yang tidak berkesinambungan antara tahun 1978 – 2014. Perubahan terlihat jelas pada total luas perubahan tutupan lahan kawasan hutan lindung tahun 1978 sebesar 43.599,04 Ha, tahun 1989 sebesar 54.599,22 Ha, tahun 2000 sebesar 26.239,654 Ha, tahun 2009 sebesar 25.817,225 Ha, tahun 2014 sebesar 26.939,535 Ha. Yang menyebabkan perhitungan luas tutupan lahan menjadi tidak berkesinambungan yaitu adanya sebaran awan dan air, sehingga mengurangi informasi luasan pada citra.

To make better the life, it is required safety foods for health. The health foods can be satisfied by organic farming that have more expensive price compared to foods derived from conventional agriculture. Organic farming is farming system based on biomass recycling or eliminating the use of materials as a synthetic agrochemical inputs. To determine whether the result of rice called as a organic product needs to be certified by the Organic Certification Board (OCB). According to the Indonesian National Standard 6729: 2013, organic farming systems are not only limited to not use material agrochemical synthetic, but must meet the requirements of organic farming systems in rice cultivation ranging from handling, storage, processing, transportation, labeling, marketing, production facilities, additional materials and other materials that are allowed start on farm to off farm should be separated from conventional agriculture. The farm is just a negate the use of agrochemicals and synthetic based on recycling without regard to the cultivation process and the system of post-harvest organic results are said to be food premium is not as organic food, because organic food is food produced from organic farming systems by applying processing practices to preserve the ecosystem of sustainable, control of weeds, pests, diseases, selection and crop rotation, water management, land preparation and planting and the use of biological materials. Thus the system of organic agriculture is a holistic production management system to improve and develop the agro-ecosystem health, including biodiversity, biological cycles and soil biological activity (Regulation of Indonesian Agriculture Ministry No. 64/2013). The first step that must be done is the conversion of land for food crops from anorganic to organic farming for 2 years did not get the requisite amount of agrochemical ingredients applied to the soil and 3 years for annual plants, after applying the organic farming system follows the Indonesian National standardization for organic farming. If agriculture in paddy soil can control the conventional farms into organic farming systems, then the resulting rice is as an organic product

The change of several soil nutrients in tidal swamp area due to addition of palm oil mill effluent (POME) on soil media. The research objective was to determine the effect of different dosages application of palm oil mill effluent on nutrient changes within planting media. This experiment was conducted in a plastic house by using 8 month ages of plants consisting of 9 pots combined with 6 levels of BOD treatment (Biological Oxygen Demand) concentrations as follows: 20.000 mg/l (L5), 15.000 mg/l (L4), 10.000 mg/l(L3), 5.000 mg/l (L2), 2.500 mg/l (L1) and water only (Lo). The plants were grown for six months from December 2014 to June 2015. The variables observed were pH (H2O), pH KCl, C-Organic, N-Total, P-Bray I (ppm), K- dd, Na, Ca, Mg, Cation Exchange Capacity, Al-dd and H-dd as well as N, P and K nutrients of crop tissues. The results showed that addition of palm oil mill effluent increased soil pH and availability of soil N, P, K, Ca and Mg. Meanwhile nutrients content of N, P and K in tissues were not increased significantly by given POME with BOD up to 20.000 mg/l.

Lad Contamination in Roadside Soil and Plant and Effect of Organic Matter Amendment (Sabaruddin, D Budianta and Mardia): Roadside soils and plants may be the most important sink of lead (Pb). It has been widely known that soil organic matter (SOM) plays important roles in determining concentrations of metals in soil solution and their extractability from the soil. To investigate Pb contamination in the roadside soils and plants, as well as the effect of organic matter (OM) on the soluble Pb in the roadside soils, surface soils (0 to 20 cm) were collected from a busy road. The soils were incubated for 4 weeks under room temperature after being treated with 0, 30, 60 and 90 Mg ha-1 of OM. Leaves of oil palms (Elaeis guineensis) planted on the roadside were also analyzed for Pb content. Current study revealed that Pb content in roadside soils and leaves of oil palm was 1.5 and 5.5 times higher than the safe level of Pb in soil and plant. It confirms that both soil and plant at the study site were contaminated by Pb. Current study also showed that SOM amendment significantly (P<0.01) affected soluble Pb content in the soils. Adding OM to the soil at 30 Mg ha-1 to correct the level of SOC from very low to low was sufficient to significantly reduce soluble Pb in the soils. However, the application of 60 Mg ha-1 of OM triggered the increases in soluble Pb in the soils. Further increases in OM application to 90 Mg ha-1 resulted in significant increases in soluble Pb as compared with that in the soil receiving 30 Mg ha-1 of OM. In spite of the increases, the level of soluble Pb in the soils receiving 60 and 90 Mg ha-1 of OM was still much below the safe level of Pb in soil.

The research was aimed to study the potency of two leguminous cover crops in enhancing tailing fertility of post tin mining with and without addition of mineral soil and compost. This pot experiment was carried out in Greenhouse of Soil Science Department, Faculty of Agriculture, Sriwijaya University from November 2011 until March 2012. Design experiment used was a Completly Randomized Design (CRD) factorial with two factors. The first factor was type of cover corps which were Centrosema pubescens and Pueraria javanica. The second factor was plant media composition which were 100% sand tailing, 60% sand tailing + 40% mineral soil, and 95% sand tailing + 5% compost. The result showed that N content on sand tailing after harvesting applied by compost and mineral soil was not significant by difference. Meanwhile, P content on sand tailing applied by compost was higher than mineral soil application and/or control (100% sand tailing).Keywords: Compost, legominous crop, N and P nutrients, sand tailing [How to Cite: Budianta D, N Gofar and GA Andika. 2013.

This research aimed to determine site specific NPK fertilizer rates combined with rice straw compost application for rice grown on the tidal lowland. This research was conducted in a greenhouse in Indralaya, Ogan Ilir, South Sumatera in February until September 2017 using a factorial completely randomized design with two factors and three replications. The first factor was NPK fertilizer rate calculated based on the results of soil chemical analysis, consisting of five levels, namely 50% (D1), 75% (D2), 100% (D3), 125% (D4) and 150% (D5) of the site-specific fertilizer rate. The second factor was rice straw compost rate consisting of two levels, namely 5 Mg ha-1 (J1) and 10 Mg ha-1 (J2). The results showed that the application of 150% NPK rate and 10 Mg ha-1 rice straw compost resulted in the best effects on the rice growth grown on the tidal lowland. The application of those fertilizer doses produced the highest maximum number of tillers and productive tillers. In this regard the doses of NPK fertilizers that should be applied are 315 kg urea ha-1, 135 kg SP-36 ha-1 and 90 kg KCl ha-1.

Palm Oil Mill Effluent (POME) cannot be directly used as an organic fertilizer source due to its high Biological Oxygen Demand (BOD) thus it is not environmentally safely. To increase the high quality of organic fertilizer obtained, the liquid wastes are needed to be processed in order to decrease the BOD to degrade both the soluble and suspension materials of organic materials. The altenative process to be conducted to make a better quality of POME is by adding the adsorbent. The aim of the research was to study the effect of zeolite utilization and duration of hydrolysis process in order to increase the nutrients content and to decrease the BOD of POME. The research was conducted at the PT Sumbertama Nusa Pertiwi Jambi, Indonesia in August 2012 until February 2013. The sample of POME was taken from the inlet of the factory’s acidulating pool. There were several doses of zeolite as treatments which were 0, 5, 10, 15% and several durations of hydrolysis process which were 1,2,3 and 4 weeks. Active zeolite was added to POME and then it was fermented with different hydrolysis duration times as mentioned above. The research showed that application of zeolite and duration of hydrolysis process significantly affected the pH, N, P, K, Al, Fe, BOD of POME and the adsorption of N, P, K, Al, Fe by zeolite. It can be concluded that 10% of zeolite incubated in two weeks duration of hydrolysis process produced higher nutrient of N, P, K with BOD, Al, Fe and pH matched with the waste quality standard. The highest efficiency of N, P and K adsorbent was show by the 15% of zeolite which was incubated for two weeks of hydrolysis process.Keyword: Hydrolysis process duration, nutrient content, palm oil mill effluent, zeolite.[How to Cite: Nursanti I, D Budianta, A Napoleon and Y Parto. 2013.Zeolite Utilization as a Catalyst and Nutrient Adsorbent of an Organic Fertilizer Process From Palm Oil Mill Effluent as Raw Material.

This study aimed to identify and explore the potential of microalgae from swampland of South Sumatra as nitrogen contributor for rice plants grown on swampland. Determination of sampling points was done by looking at the presence and abundance of microalgae in the sampling locations. The method used in the sampling is purposive sampling method. The samples were grouped into 3, i.e. culture 1 (B1) derived from rice cultivation area, culture 2 (B2) derived from land that was not cultivated with rice, and culture 3 (B3) derived from swamp water samples. The medium used to culture the microlagae was Johnson's medium. The variables measured were the number of microalgae cells and ammonium concentrations on day 1, 4, 8 and 16 of culturing. Three species of Cyanophyceae class from the swampland were identified, i.e. thread algae, Synedra sp. and Melosira sp. Those microalgae may contribute the maximum amount of available nitrogen of 21.41 ìg mL-1 in the form of ammonium to the rice plants on days 10-12. Microalgae in culture 1 can contribute nitrogen for rice plants in the form of ammonium about 16.23% - 48.71% with the cell density of 7.48 cells mL-1.
