Abstract

Palm oil mill effluent (POME), discharged by palm oil processing industry, is potentially recovered as substitution of AB mix, a nutrient solution for hydroponic. The objective of this research is to test the use of the treated POME in the mixture with AB mix to cultivate green mustard. The method in this study uses a factorial Completely Randomized Design (CRD) with 2 factors.  The first factor, namely POME (K) consists of 2 levels, namely Pond 3 (K3) and Pond 4 (K4).  The second factor is the mixture of AB Mix and POME, which consists of 5 levels of the POME percentages namely: 0% (P0), 25% (P25), 50% (P50), 75% (P75), and 100% (P100). Results showed that the increasing percentages of POME additions tended to decrease the growth of green mustard. The best treatment was obtained on treatment of P0, 100% AB mix with no POME addition based on plant height, number of leaves, and water consumption. Keywords: AB Mix, Green Mustard, Hydroponic, POME, Wick System

Abstract

Efforts to increase the production of sweet corn can be done with the application of fertilizers, either inorganic, organic orits combination. In addition, the application of soil amendments such as biochar is also expected to improve soil fertility that will indirectly increase the production of sweet corn.Organonitrophos fertilizer is an organic fertilizer developed by lecturers of Faculty of Agriculture, University of Lampung. The research was aimed to study effect the combination of organonitrophos, and inorganic fertilizers, biochar and the interaction between fertilizer combination and biochar on soil respiration and soil microbial biomass.The research was conducted in the Integrated Field Laboratory of Lampung University using 6x2 factorial in a Randomized Block Design with 3 replications. The first factor was six levels combination of organonitrophos and inorganic fertilizers (P0, P1, P2, P3, P4, and P5). The second factor was two levels of biochar dosage (B0 and B1). Data was analyzed by Analysis of Variance and followed by the Least Significant Difference (LSD)Test at 5% level. The observed variables were soil microorganism activity likely soil respiration and soil microbial biomass. The results showed that P3B1treatment (300 kg Urea ha-1, 125 kg SP-36 ha-1, 100 kg KCl ha-1 + 2500 kg organoitrophos ha-1) was the highest soil respiration at of 60 days after planting (DAP). P5 treatment (5000 kg Organonitrophos ha-1) has the highest soil microbial biomasscompared to other treatments at 60 and 90 DAP. B1 treatment (5000 kg biochar ha-1) has higher soil respiration and soil microbial biomasscompared to treatment (0 kg biochar ha-1. There was an interaction between combination of organonitrophos and inorganic fertilizers and biochar on soil respiration at 90 DAP. However, there was no interaction between fertilizer combination and biochar on soil microbial biomass.Keywords: Biochar, Fertilizer Combination, Organonitrophos, Soil Microbial Biomass Carbon and Soil Respiration

Abstract

The field and laboratory experimental studies were conducted to determine the phosphorus (P) adsorption behavior employing Langmuir Method and yield of sugarcane as affected by compost and inorganic fertilizer applications, and to determine the correlations between the Langmuir parameters and the availability of P in soil or harvested P by the sugarcane. Both field and lab experiments were arranged in a randomized block design, consisting of five treatments (A= 100% NPK, B=100% compost, C=100% NPK + 50% compost, D= 50% NPK + 100%, compost, and E= no fertilizer).  Each treatment was replicated three times. Field and laboratory studies were carried out in the sugarcane field and in the Laboratory of Soil Science, the University of Lampung for Langmuir P studies, respectively. The results showed that the applications of 100% NPK plus 50% organic fertilizer, and 100% NPK resulted in the highest amount of available-P in the soil, the lowest maximum adsorption of P (Xm) and the lowest relative bonding energy of P (km); as well as the highest effect on the increase of sugarcane production. On the other hand, the treatments of no fertilizer and the 100% organic fertilizer resulted in the highest maximum adsorption of P (Xm) and the lowest sugar production. There were very significant negative correlations between the maximum adsorption of P (Xm) and soil P, harvested P by the sugarcane and stem biomass; while similar trend but no significant correlations between the relative bonding energy of P (km) and soil P, harvested P, leaf biomass and stem biomass were detected.

Abstract

Model Simulation of “Sawah-Kolam” System for Rainwater Harvesting to Support Rainfed Paddy Production (S Triyono, Zeovany, Oktafri, and B Rosadi): The study was used to evaluate whether rainwater could be harvested and used to meet water demand of rainfed paddy.  As generally known, yield of rainfed paddy was low compared to that of irrigated paddy.  The study was performed by simulating a model of “Sawah-Kolam” system.  Daily 10 year climatological data from Metro City of Lampung Province was used in the study.  The program was written in Professional VisSim 4.0.  Three scenarios of alternative planting schedules (January, February, and March) were tested.  Results implied that without a collection system, rainwater might not be sufficient to grow rainfed paddy.  It was demonstrated that “Sawah-Kolam” system was capable of sufficing water requirement of rainfed paddy.  Huge rainwater of more than 90% could be saved, thus reducing a lot of runoff volume.  In term of pond size, February appeared to be the most optimum growing season of all other months for Metro City, in that the pond area (1,400 m2) required was the smallest.

Abstract

Microbial N2-fixer and P-solubilizer were innoculated in a mixture of fresh manure and phosphate rock formulated as an Organonitrophos fertilizer. The population dynamics of bacteria and fungi growing during the composting process were observed. The inoculation treatments consisted of: K = mixture of 20% phosphate rock and 80% of fresh manure + decomposers (control), N = mixture of 20% phosphate rock and 80% of fresh manure + decomposers + N2-fixer (Azotobacter and Azospirillum sp.) , P = mixture of 20% phosphate rock and 80% of fresh manure + decomposers + P-solubilizer (A. niger and P. fluorescens), and NP = mixture of 20% phosphate rock and 80% of fresh manure + decomposers + N2-fixer + P-solubilizer. The results showed that inoculation of microbial N2-fixer and combination inoculation of N2-fixer and P-solubilizer increased the total bacterial population compared to that of the control as well as the only inoculation of microbial P-solubilizer on the 14th day of observation in which the bacteria reached the highest population. On all the observation days, the population of fungi in the inoculation of microbial P-solubilizer treatment increased significantly compared to that of the control. However, there was no difference between the populations of fungi in the inoculation of N2-fixer and combination inoculation of N2-fixer and Psolubilizer. The genus of fungy identified in the compost of the mixture of fresh manure and phosphate rock were Chytridium sp., Aspergillus sp., Rhizopus sp., and Fusarium sp.[How to Cite : Nugroho SG, Dermiyati, J Lumbanraja, S Triyono, H Ismono. 2013.

Abstract

A field experiment was conducted to find out a combination dose of a novel organic fertilizer (Organonitrophos, OP) and inorganic fertilizers (N, P, and K) for the growth and yield of cassava (Manihot esculenta Crantz) during two planting periods of 2012-2013 and 2013- 2014 in ultisol soil (low in nutrients and organic matter) of Bandarlampung. The treatments were a six combination of organic and inorganic fertilizer. The experiments were laid out in a randomized block design with three replications. The difference combination of Organonitrophos and NPK fertilizers showed significantly effects on the plant height, the NPK sorption of total plant and total root, and the yields of cassava. The highest NPK sorption of total plants and total yields and the highest yields of cassava were found in N45P36K120OP1,000 kg ha-1 combination for the two planting periods. Based on Relative Agronomic Effectiveness (RAE) of cassava root yield, it can be concluded that 45-36-120-1,000 N-P-K-Organonitrophos kg ha-1 was the best combination dose of inorganic and organic fertilizers for the production of cassava in ultisol soil of Bandarlampung.

Abstract

This study aimed to examine Organonitrofos Plus fertilizer (OP) on sweet corn (Zea mays Saccharata L.) and its effect on changes in soil chemical properties of Ultisols. Organonitrofos Plus fertilizer is an enhancement of Organonitrofos fertilizer enriched with microbes at the beginning of the manufacturing process. Research was conducted in the greenhouse of Integrated Agricultural Laboratory of Lampung University. Treatment applied was a factorial of 4 × 2 × 3 with three replications in a randomized block design. The first factor was the dose of OP fertilizer (0, 10, 20, 30 Mg ha-1), the second factor was the dose of inorganic fertilizers (without inorganic fertilizers, and with inorganic fertilizers, namely Urea 0.44, 0.28 SP-36 and KCl 0.16 Mg ha-1), and the third factor was the dose of biochar (0, 10, 20 Mg ha-1). By a single OP fertilizers, inorganic fertilizers, and the interaction between the OP and the inorganic fertilizers increased the weight of dry stover, cob length, cob diameter, cob with husk and cob without husk of corn. OP fertilizers which are applied in Ultisols can improve soil fertility and increase corn production so that OP fertilizer can lessen the use of inorganic fertilizer and can be used as a substitute for inorganic fertilizer. RAE values were highest in treatment of O4K2B2 (30 Mg OP ha-1, with inorganic fertilizer, 10 Mg biochar ha-1) that was equal to 181%, followed by O2K2B3 (10 Mg OP ha-1, with inorganic fertilizer, 20 Mg biochar ha-1 ) with the difference in RAE value of 0.5%.

Abstract

The high volume of fruit waste in Lampung and Indonesia in general requires environmentally friendly waste management solutions. This study aims to utilize such waste for liquid organic fertilizer by evaluating the effects of mixing fruit waste-based liquid organic fertilizer (LOF) with AB Mix nutrients on the growth of red spinach (Alternanthera amoena Voss) in a Static Aerated Technique (SAT) hydroponic system. The research employed a Completely Randomized Design (CRD) with a single factor, consisting of five treatment combinations of LOF and AB Mix concentrations (0–100%) and three replications. Observed parameters included plant height, number of leaves, plant weight, root length and weight, stem diameter, and water use efficiency. The results showed that the use of pure AB Mix (100%) produced the best growth outcomes compared to the mixed or pure LOF treatments. The lower growth and productivity in the LOF treatments were attributed to the low levels of macronutrients (N, P, K) in the produced LOF, as well as the presence of sediment that hindered nutrient absorption and the upward flow of nutrient solution from the reservoir to the plant root zone. Nevertheless, the combination of LOF and AB Mix still shows potential as an alternative nutrient source for hydroponic cultivation if optimally formulated.  Keywords:  AB Mix, Fruit Waste, Liquid Organic Fertilizer, Red Spinach, SAT Hydroponics,

Abstract

Palm oil mill effluent (POME) and oil palm empty fruit bunches (OPEFB) represent two major waste streams in the palm oil industry that pose serious environmental challenges but also offer significant opportunities for renewable energy generation. This review comprehensively discusses the development of biogas production from POME through anaerobic digestion (AD) and explores the prospects of co-digestion with OPEFB to improve system efficiency and sustainability. A systematic literature survey of over 150 publications from the past four decades was conducted to evaluate technological evolution, operational parameters, methane yield, and environmental implications. The review identifies five major phases of POME biogas development—from early feasibility studies in the 1980s to the current exploitation phase integrating energy recovery, carbon credit schemes, and circular bioeconomy principles. Anaerobic digestion of POME in covered lagoon systems has achieved COD removal efficiencies exceeding 90% and methane yields of 0.28–0.34 Nm³ CH₄ per kg COD removed, supporting electricity generation potentials above 1 GW nationwide. Meanwhile, co-digestion with OPEFB enhances process stability, optimizes the C/N ratio, and improves methane production by 20–40% depending on substrate ratio and pretreatment. The integration of POME–OPEFB co-digestion can substantially reduce greenhouse gas emissions and provide value-added biofertilizers, thereby strengthening the environmental and economic sustainability of palm oil mills. Despite technological advances, several challenges remain, including high investment cost, OPEFB pretreatment, and limited policy support for grid connection. Further development of scalable, low-cost digesters and biogas upgrading systems is essential to realize the full potential of biogas as a renewable energy pathway within the palm oil sector.
