Abstract

The research attempts to analyze the phytochemical compositions of both the leaves and the cherries of coffee and examine preference through the sensory evaluation of consumers consuming tea products of Robusta coffee from Songkhla, Thailand. The methods used for the phytochemical analysis were conducting an antioxidant content analysis using the Ferric ion reducing antioxidant power method, conducting total phenolic and tannin contents analysis using the Folin-Ciocalteau method, and conducting a total flavonoid content measurement using the aluminum chloride colorimetry method. For the sensory evaluation of tea products (leaves and cherries of coffee), a set of questionnaires was used as the survey observation tools to collect the data from consumers at some coffee and tea shops. The data analysis was using T-test for phytochemical composition and F-test on sensory evaluation. This study shows that Robusta coffee leaves and cherries contained phytochemical compounds of different values. Compared to the cherries, the leaves had higher values of phytochemical compositions. Based on the sensory evaluation of consumers, tea products made from leaves and cherries were highly rated. Coffee cherry tea demonstrated a higher percentage of interest compared with coffee leaf tea.

Abstract

This study aimed to obtain resistance information of S. litura from Karangpawitan and Lembang districts (West Java, Indonesia) against chlorpyrifos insecticides (200 g/l) and their sensitivity to oil mixture of A. indica and C. nardus (1:1) using feeding and topical assay. The activity of acetylcholinesterase, esterase, and glutathione s-transferase from S. litura larvae in both populations were tested to determine their role in insect resistance. Results showed that S. litura population from Lembang had a higher level of resistance to chlorpyrifos compared to Karangpawitan. The sensitivity of the two S. litura populations had a relatively similar resistance ratio (RR) value of less than 1 to botanical insecticide. These indicated that resistant population could be controlled by a mixture of this botanicals insecticide. Enzyme activity test indicated that chlorpyrifos at a concentration of 0.26% could inhibit the acetylcholinesterase activity of insect population from Karangpawitan by 98.66% while those from Lembang, it was only 35.31%. Specific activity of esterase from Karangpawitan was 13.37 units/mg while Lembang population was 119.65 units/mg. The specific activity of the Glutathione S-Transferase (GST) of Karangpawitan population was 1140.82 units/mg while Lembang population was 793.73 units/mg. The high activity of the three enzymes could be responsible for resistance of S. litura larvae to chlorpyrifos.

Abstract

Excessive agricultural waste potentially causes serious pollution issues by farming practices. The potency of Basidiomycota’s fungi to degrade biomass for a safe practice might be considered to cope with this issue. This study aims to determine Basidiomycota fungi’s ability to produce organic acids after being inoculated on cocoa husks at various fermentation periods (20 and 40 days) and evaluate the effect of humic acid from those fermented cocoa husks on the growth and productivity of shallots. This research is carried out in three stages; the first is composting process from cocoa husks. The next is the acid-base extraction of cocoa pod husk compost to produce humic and fulvic acid. And the last is the application of humic acid to shallot plants. The results show that composting for 40 days produced higher levels of humic and fulvic acids. Inoculation with Coprinus sp produced the highest levels of humic acid but is not different with Pleurotus sp. Applying 100 ml/l of humic acid to shallots shows the best growth, while the concentration of 400 ml/l has the best production. This study presents the potential practice of cocoa pod residue and Basidiomycota fungi to increase agricultural commodities’ productivity agents.

Abstract

The growth of entomopathogenic fungi Lecanicillium lecanii is strongly related to the media in increasing the fungi sporulation, enhancing its effectiveness in infecting target pests. This study aims to obtain L. lecanii propagation media with the highest conidia production, and the increased virulence on Cylas formicarius. The first stage of alternative media selection consists of: Potato Dextrose Agar; maize, rice; bran. The second stage of infectivity of the best alternative media consists of 5 treatments in 5 replications: synthetic insecticide (C+); distilled water (C-); 107 conidia/ml; 108 conidia/ml; 109 conidia/ml. The results show that the best colony growth rate is (1.15 mm) on Maize media, and the highest conidia density is (4.2 x 10⁸ conidia/ml) on Maize media is not significantly different from PDA (1.3 x 10⁸ conidia/ml). The best germination rate is (74.31%) on Maize media, and the highest media weight (1.10 g) on Rice media is not significantly different from maize (1.45 g). The infectivity of L.lecanii affect the mortality of C. formicarius (74%) substantially at a concentration of 109 conidia/ml. The LC50 value obtained is 2.6 x 10⁷ conidia/ml. Thus, maize media can be an alternative medium for mass propagation of L. lecanii.

Abstract

The aim of this research is to find the characteristics of three PGPR isolates—Azospirillum sp., Bacillus sp., and Pseudomonas sp.: First, by profiling their characteristics in a liquid bioremediation system and secondly by measuring their performance as a bioagent in a soil phytoremediation system using ramie plant (Boehmia niviea L.). A Randomized Block Design in triplicate is used: (1) a Nitrogenfree medium with mineral media containing 1% (wt/v) petroleum hydrocarbons; and (2) 1% (wt/v) glucose medium as control. We tested their petroleum-degrading capacity, nitrogenase activity, phytohormones production, and ramie plant growth. The results showed that both Pseudomonas sp. (98.7%, 81.78% degradation efficiency) and Azospirillum sp. (93.80%, 83.70%) were the superior candidate in both systems. They both show reduced but adequate phytohormone production, managing to improve ramie plant growth. Both also showed reduced but sufficient nitrogen fixing capabilities to improve hydrocarbon degradation activity effectively. Meanwhile, Bacillus sp. has the lowest biodegradation capabilities (84.07%; 78.6%) and lowest nitrogenase activity, while failing to improve plant growth. Therefore Bacillus sp. would be more beneficial in a bacterial consortium where its characteristics (high IAA production) can be coupled with other isolates that can offset its lack of phytohormone or nitrogenase activity.

Abstract

The melon fly, Bactrocera cucurbitae is serious pest attacks fruits and vegetables. The manipulation of male mating behavior that displays acoustic signals is one of the steps in the behavior-based control strategy of B. cucurbitae. The first study period determines the courtship song characteristics, frequency, and occurrence time. The recording was carried out when B. cucurbitae was mated using recording devices at 04.00–07.00 pm. The results show three sounds produced before copulation, namely, calling, courtship, and stimulating, with frequencies 274.30 ± 3.29 Hz, 284.65 ± 2.00 Hz, and 304.36 ± 1.82 Hz. B. cucurbitae courtship song began at 04.00–06.26 pm. The second study was performed to determine the effect of experimental acoustic playback stimulus on the selection of mating pairs by females. The acoustic playback stimulus is made synthetically by playback of two channels, namely, calling and courtship sounds, with frequencies of 274 and 284 Hz at a sound pressure level (SPL) of 85 dB. The experimental results of acoustic playback stimulus show that the sexual behavior of female B. cucurbitae was disrupted and marked by the decreased number of copulations during SPL is high, resulting in the overlapping calling and courtship sounds frequencies that impair signal detection.

Abstract

This study aims to determine the response’s incompatibility of selected dwarf citrus rootstock after treated by abiotic stresses such as drought, waterlogging, and acidity on a scion. The results of this study was selected seedlings for sub-optimal lands in Indonesia with dwarf growth characteristic and compatible with the grafted-scion. The preliminary study has shown that there were 3 (three) selected rootstock accessions with dwarf characteristics, namely Citromello (Cit), Volkameriana (Volk), and Cleopatra Mandarin (CM). The seeds of these accessions were treated with 8% Polyethylene Glycol (PEG), 150% FC; 9 mM Al2SO4 at eight months after planting. Each rootstock was grafted with Pontianak orange (C. nobilis var. microcarpa). The results showed that Citromello (Cit) and Volkameriana (Volk) are incompatible rootstock and dwarf potential seedling. However, Cleopatra Mandarin has a compatibility with the grafted scion and is tolerant of abiotic stress treatments. The effect of abiotic treatment on Citromello resulted in 15% higher root length higher than other accessions. Furthermore, this variety has 40% dry weight and 25% lateral root numbers, respectively, by Al2SO4 and PEG. Meanwhile, Volkameriana had the 40% higher number of leaves.

Abstract

Virus infection in chili plants may cause various symptoms. The complexity of the symptoms and human vision ability often become limiting factors during disease investigations. Digital image analysis is expected to become a method to assist in comprehensively describing the symptoms of plant viruses. A disease survey was conducted on cayenne pepper fields in Southeast Sulawesi Province to observe symptoms of virus infection virtually and to record the symptomatic plant using an RGB camera. The split-channel method is used to process images, followed by multidimensional scaling statistical analysis. Later on, viruses associated with plants were detected serologically. Single or mixed infection of Tobacco mosaic virus, Cucumber mosaic virus, Chili veinal mottle virus, and Pepper mottle virus was confirmed by plant leaves showing yellow-mosaic and mottle symptoms. The digital image analysis method could show variations in the characteristics of symptoms based on digital numbers in that cannot be recognized based on the observation of visual symptoms. A new approach to study the interactions between plant infecting viruses and their effects based on image analysis has also been developed during this research. This method needs to be further validated through testing under controlled conditions, such as inoculating plants with a predetermined type of virus.

Abstract

Pleurotus species are the common mushrooms popularly cultivated in the Philippines while Fermented Plant Juice (FPJ) is a known organic concoction which can help crops to grow. This study aimed to find out the effects of FPJ on the mycelial growth, basidiocarp production and sensory attributes of different species of Pleurotus in culture media, grain spawn and fruiting substrates supplemented with varying amounts of FPJ. The experiment was laid out in complete randomized design and replicated thrice for culture media and grain spawn; and replicated ten times for the fruiting substrates. P. florida in 20 ml culture media supplemented with 2.4 ml of the 120 ml FPJ solution had the fastest mycelial growth while P. citronipleatus in grain spawn supplemented with water had the fastest mycelial growth. P. ostreatus grown in 750 g dry weight of fruiting substrates supplemented with 150 ml of FPJ had 6.83 higher yield than the control, thus higher profitability and Return on Investment (ROI). Significant differences were also observed on the sensory attributes such as taste, aroma and general acceptability. Majority of the respondents liked P. florida which is considered as very much palatable. As the concentration of FPJ become higher, the taste becomes better.

Abstract

The availability of seeds is one of the most essential aspects of agricultural development in developing countries and Indonesia is no exception. This requires adequate technological innovation and institutional support. This study aims to describe the synergy of innovation at the level of national companies that provide hybrid corn seeds to farmers. Three levels of company performance were compared namely well-established companies, middling, and less-developed companies. The results showed the performance of hybrid corn seed companies from 2019 to mid-2022 was mainly influenced by the degree of synergy between seed companies and their supporting institutions in implementing improvements in seed production technology. Established companies have better synergy with supporting institutions, hence, they can adequately apply seed production technology producing 4,900 tons of quality seeds, and distributing them to various regions specifically 12 provinces. Meanwhiles, companies that have low synergies with their supporting institutions are very weak, producing seeds only in small quantities at 400 tons. This implies that technological innovations and institution synergy for hybrid corn seed production can be applied by national companies with adequate support from local institutions.
