Abstract

Recently, people have suffered from many serious illnesses, such as  kidney, cancer, osteoporosis, etc. One of the triggers is that the food eaten by human is not free from heavy metals. These heavy metals enter through the food chain during the crop cultivation. These heavy metals can come from artificial agrochemical inputs (such as synthesis P fertilizers and pesticides). One way to avoid the entry of heavy metals into plant is by implementing organic farming. Organic farming is an agricultural system that does not use synthetic chemical. The implication of organic farming are (1) maximizing the use local resources, (2) minimizing the use of chemical inputs, (3) ensuring biological functions, (4) maintaining a diversity of plant and animal species, (5) creating an attractive overall landscape that provides satisfaction for local communities, and (6) increasing the intensity of plants and animals in the form of polyculture, agroforestry, crop/animal systems integrated livestock etc. If organic farming principles are followed consistently then the food produced will be healthy and safe for humans and animals and save for land sustainability to support smart farming. Another benefit of organic farming is that natural resources will be sustainable and the environment will be protected from pollution and damage. To convince the Indonesian and global community, the organic products produced must be certified independently, the basis of which is SNI 6729-2016.

Abstract

Sorghum (Sorghum bicolor L. Moench) plant is native to tropical and subtropical countries with high suitability for planting on marginal land. Therefore, this research aimed to determine the use of dolomite and vermicompost in tidal swamp soil for the growth and yield of sweet sorghum plants at the Experimental Garden and the Chemistry, Biology and Soil Fertility Laboratory, Department of Soil Science, Faculty of Agriculture, Sriwijaya University. A factorial randomized complete block design (FRCBD) consisting of two factors was used. The first factor was dolomite namely 0 ton.ha−1, 6 ton.ha−1, 9 ton.ha−1, and 12 ton.ha−1, while second factor was vermicompost including 0 ton.ha−1, 3 ton.ha−1, 6 ton.ha−1, and 9 ton.ha−1. The results showed that the application of Dolomite had a very significant effect on soil pH, N-total, P-available, and potassium exchangeability. In addition, dolomite increased plant height, number of leaves, chlorophyll content, fresh and dry weight shoot, number of grains, and weight of 1000 grains.

Abstract

This study investigates the adoption of Climate-Smart Agriculture (CSA) practices among predominantly traditional rice farmers in South Sumatra, Indonesia, and proposes strategies for enhancing resilience to climate variability. A total of 98 farmers across nine districts participated in  structured surveys and in-depth interviews. The results showed a reliance on modern machinery for land preparation (62.8%) alongside a considerable use of traditional tools (26.5%). High awareness of climate change (87.9%) and its impacts, along with a substantial understanding of the negative effects of chemical fertilizers (67.7%), were observed. The use of weather forecasts by 34.7% of respondents highlighted the importance of reliable climate information in agricultural decision-making. Adaptive practices for drier conditions include water management (40%) and crop management methods (25%), while improved drainage (40%) and other flood prevention measures (35%) were commonly adopted for wetter conditions. Despite these efforts, 50% of farmers reported decreased productivity during dry seasons due to the significant impact of irregular rainfall, while approximately 42% managed to increase productivity during wetter conditions through adaptive practices. To enhance CSA adoption, continuous education and awareness programs, promoting energy-efficient machinery and organic farming methods, and improving access to accurate weather forecasts are recommended. The development of resilient crop varieties and the provision of financial and technical support are also essential. Implementing these strategies can facilitate the integration of CSA into the farming system, ensuring a resilient and sustainable agricultural sector in South Sumatra that supports both productivity and environmental preservation, contributing to long-term food security and sustainable development in the region.

Abstract

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.

Abstract

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.

Abstract

Changes in Some Soil Chemical Properties of Ultisol Applied by Mulch from Empty Fruit Bunches in an Oil Palm Plantation (D Budianta, AYA Wiralaga, and W Lestari):  Objective of this research was to study the effect of empty fruit bunches (EFB) applied as mulching on some soil chemical properties of Ultisol in an Oil Palm Plantation. This field experiment was conducted in PT. Sampoerna Agro Tbk Plantation Mesuji, Ogan Komering Ilir of South Sumatra Province at blocks of 22/A, 23/B, 27/C, 33/, 12/A, 12/B, 24/D, 12/C, 00/C, 24/A, 24/B, 10/B, 02/C, 02/D, 11/C, 11/D, 10/A, 10/C, 11/A, and 24/C. The treatment was EFB dosage which are without EFB (control), 40 Mg ha-1 of  EFB applied only once for a year, 80 Mg ha-1 of EFB applied twice for 2 years, 120 Mg EFB/ha applied three times for 3 years, and 160 Mg ha-1 of EFB applied four times for 4 years. The rate of EFB application was 40 Mg ha-1 per year. Every treatment was replicated 4 times, thus total of experiment was 20 units. Soil samples were taken in two differences of deepness which were 0-20 cm and 20-40 cm, respectively. Soil variables observed were soil pH, organic C, cation exchange capacity (CEC), total N, P availability, exchangeable K and Mg, Al and Fe. The results showed that application of EFB had significantly effect on some soil chemical properties such as soil pH and Mg exchangeable Mg for 0-20 cm and total N for 20-40 cm deepness. Meanwhile application of EFB did not have siginificant effects on total organic C, CEC, P-Bray I, exchangeable K, exchangeabile Al and Fe.  It was also shown that some soil chemical properties were generally higher in top soil layer than sub soil layer, except for CEC, P and  exchangeable Al.

Abstract

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.

Abstract

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.

Abstract

The specific location fertilization or in situ fertilization rate is a dynamic application and management method dynamically adapted to the plant’s need according to location and season related to soil chemical properties and aims to increase farmer profit. This greenhouse experiment aimed to evaluate the NPK fertilizer dose based on in situ soil chemistry of tidal swamp compared to NPK recommendation combined with cow manure from the local farm. These pot experiments were conducted from June to October 2019 in a Greenhouse of Soil Science Department, Faculty of Agriculture, Sriwijaya University, Indralaya, Ogan Ilir of South Sumatra.  This experiment used a factorial completely randomized design with two factors and three replications. The first factor was NPK fertilizer rate consisting of two levels (200 kg ha-1 Urea, 100 kg ha-1 SP-36, and 100 kg ha-1 KCl) from recommended fertilizer, and (102 kg ha-1 Urea, 0 kg ha-1 SP-36, and 66 kg ha-1 KCl) from the in situ soil analysis. The second factor was cow manure with four levels (2, 6, 8, and 10 Mg ha-1). The result showed that recommended NPK combined with 10 Mg ha-1 cow manure was the best for rice production in tidal lowland and produced 2.5 Mg ha-1.  However, this result was not significant compared to NPK specific locations combined with the same rate of cow manure.
