Newly Hatched Larvae

An experiment was conducted to compare the suitability of chicken, pig, and cow manure as feed for larvae of the black soldier fly (Hermetia illucens (L.); Diptera: Stratiomyidae). Newly hatched larvae were inoculated on moistened manure (33% dry matter). Water and dried manure were added three times per week, until the first prepupae appeared. Survival was between 82 and 97%, indicating that the tested substrates were suitable. However, development time was much longer than on the control diet (144-215 vs 20 days). Efficiency of conversion of ingested nitrogen (N-ECI) was higher on pig manure than on chicken and cow manure, while the ECI for phosphorus was highest on cow manure. Substrate nitrogen content decreased in the chicken manure, but were stable in pig and cow manure. Phosphorus concentration, and N:P-ratio decreased in all treatments. Since a large proportion of the nitrogen from the manure (23–78%) was lost, the production system would require an air washer for instance, to make it ecologically sound. Shorter development times are required in order to improve economic viability. Drying of the manure could have decreased its nutritional value due to the destruction of microorganisms and heat-labile vitamins. A production system using fresh manure could result in a considerably shorter development time and increased conversion efficiency.

Dry Digestion

Dry anaerobic co-digestion of animal manure and straw was conducted to produce biogas. Startup characteristics and biogas production perform of dry digestion were studied, and the effect of operation temperature and incubation amount on dry digestion was also investigated. The study result showed that under the conditions of C/N=25-30, TS=20% and T=(36±1) °C,dry digestion can start up quickly with acclimated thickening sludge as incubation sludge. Compared to dry digestion of chicken manure and pig manure, dry digestion of cow manure proceeded steadily with high biogas yield. It is found that incubation is necessary in the process of dry digestion and biogas yield increases with more incubation amount. The appreciate incubation ratio is about 10%. Temperature change has apparent effect on biogas production, and it is suggested that mesophilic temperature should be chosen in the scaled project of dry digestion.

Cyanobacterial Biomass

Cyanobacterial biomass is important for biofuel and biofertilizer, however, biomass production requires expensive chemical growth nutrients. To address this issue, we explored the use of inexpensive growth nutrient media from an integrated manure-seawater system for cyanobacterial biomass production. Salt-tolerant cyanobacterial strain HSaC and salt-sensitive cyanobacterial strain LC were tested to evaluate the potential of integrated manure-seawater media for sustainable cyanobacterial biomass production. As a prerequisite for seawater experiments, strain HSaC was grown at different NaCl concentrations (0 mM, 60 mM, 120 mM, 180 mM, 240 mM and 300 mM) to identify the optimum salt concentration. The highest biomass yield and photosynthetic pigment contents were obtained at 120 mM NaCl concentration. The highest exo-polysaccharide (EPS) content was obtained at 180 mM NaCl concentration. The treatments for the manure-seawater media were cow manure, pig manure, chicken manure and BG11, each with distilled water, diluted seawater and non-diluted seawater. The highest biomass and photosynthetic pigment yield for cyanobacterial strains LC and HSaC were obtained from 0.5 dS/m and 10 dS/m diluted seawater integrated with cow manure, respectively, but pig and chicken manure performed poorly. Overall, the biomass production and photosynthetic pigment results from cow manure-seawater were relatively better than those from the reference media (BG11). Based on the current findings, it is concluded that the growth nutrients from integrated cow manure-seawater can wholly substitute for the BG11 without affecting cyanobacterial growth, thereby reducing the usage of expensive chemical growth media. Thus, the results of study help to enhance the biomass production of both salt-sensitive and salt-tolerant cyanobacteria for sustainable biofuel and biofertilizer production.

Water spinach (Ipomoea reptans Poir) had been identified as a nutritious vegetable with high demand in Indonesia. Besides, this plant also has been evidenced to play an important role in environmental cleaning as phytoremediator. The study about the effect of organic fertilizers on the growth and yield of water spinach (Ipomoea reptans Poir) has been conducted in the Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. The study aims to investigate the most effective type of fertilizers and the dose for water spinach’s (Ipomoea reptans Poir) growth and yield. A Completely Randomized Factorial Design was designed for the experiment with two factors and three repetitions. The first factor is the type of fertilizer (chicken manure, cow manure, and compost), and the second factor is the dose of the fertilizer (1:1, 2:1, and 3:1). The parameters such as plant height, number of shoots, number of leaves, fresh weight, dry weight, leaf’s total chlorophyll content, and water content were measured to evaluate plant growth and yield. The General Linear Model used SPSS 21 programs was applied to analyze the collected data. Study results revealed that cow manure increased plant growth and yield significantly with dose 2:1 as the finest treatment, followed by dose 3:1. Cow manure also increased total chlorophyll content (8.0574c mg. L-1), with the most suitable dose was 2:1 (8.2807 mg. L-1). The plant’s water content tended to be high in chicken manure (93%), and the lower water content was in cow manure with dose 3:1 (87.5%).

In a situ buried-bag experiment, the seasonal dynamics of soil total organic carbon (TOC) and labile organic carbon in soil amended with maize stalk (MS), chicken manure (CM), pig manure (PM) and mixture of them (MI) were studied in one year. MS with a low N content and high C/N ratio decomposed a little faster than other materials with low C/N ratios. Labile carbon pool – microbial biomass carbon (MBC) and light fraction of organic carbon (LFOC) exhibited an absolute difference in the 365-day incubation period: MS in MBC showed a gentle ascendant tendency; however, CM and PM displayed a rapid decrease. The concentrations of LFOC in all the treatments decreased coincidently nevertheless. MBC was more sensitive to organic material addition than other labile pools, despite of its low level.

Palu Valley shallot production is still very low namely 5.31 tonnes/ha when compared to national production which reaches 9.7 tonnes/ha, this is due to the attack of the base stem rot disease caused by Fusarium oxsyporum f.sp. cepae. This study aims to determine the effect of various types of organic fertilizer decomposed by Trichoderma virens on the incidence of stem rot disease and shallot yields. The research was conducted at the Laboratory of Pests and Plant Diseases, Faculty of Agriculture, Tadulako University, and shallot planting in Oloboju Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi Province and lasted from March 2018 to August 2018. This research used a Randomized Block Design (RBD) with five treatments consisting of, without organic fertilizer (B0), cow manure 10 tons/ha + Trichoderma virens 100g/L (B1), chicken manure 10 tons/ha + T. virens 100g/L (B2), goat manure 10 tons/ha + T. virens 100g/L (B3), and petrogenic 5 tons/ha+ T. virens 100g/L (B4). The results showed that the use of 10 tons/ha cow manure decomposed by T. virens (B1) can reduce the intensity of stem rot disease on the Palu Valley shallot which is 5.61% to be 1.88% (3rd week) and 2.89% to be 0.98% (7th week), and increase shallot yield from 4.09 tons/ha to be 7.48 tons/ ha.
