Published: June 2024

Abstract
Soybeans are an essential commodity for Indonesian people, who still rely on imports to meet national needs. Agroforestry is one of the solutions to increase soybean production. Agroforestry systems have different conditions from agricultural land in general. Trees such as pine and mahogany can influence the presence of other organisms that can potentially interfere with crop growth. Bacterial pustule is an important disease of soybeans caused by Xanthomonas axonopodis. The research aimed to observe disease incidence in soybeans in pine and mahogany agroforestry systems. This research was conducted at KHDTK Forestry-Alas Bromo in Karanganyar, Central Java, Indonesia. The study used a completely randomized block design with six varieties of soybeans planted in an agroforestry system with mahogany and pine fields. The varieties were Argomulyo, Dena-1, Dena-2, Denasa-1, Denasa-2, and Devon. The research showed that no pustule bacteria were observed in the agroforestry system with pine. However, soybeans in agroforestry systems with mahogany were infected by pustule bacteria with an incidence of up to 40%. No infection on agroforestry soybeans in pines is presumably related to the microclimate condition. The microclimate conditions in pine agroforestry are more open and hot, while in mahogany, agroforestry conditions are more humid and less exposed to sunlight.

Abstract
Phosphate-solubilizing bacteria (PSB) play important roles in the agricultural systems. The present study aims to compare the population density, colony diversity, and phosphate solubilization ability between rice root endophytic bacteria (RRoEB) and rice rhizospheric soil bacteria (RRzSB) from organic wetland. By spread plate method, bacteria were isolated directly using Pikovskaya’s agar and indirectly through other media, namely Nutrient Agar (NA), Starch Casein Agar (SCA), Jensen, and Yeast Extract Mannitol Agar (YEMA). Each distinct colony based on the morphology on the respective media was screened for phosphate solubilization ability by subculturing on Pikovskaya’s agar. The phosphate solubilizing index (PSI) was measured from the halo zone formation. The results showed that by direct isolation, 6 RRoEB and 5 RRzSB were able to phosphate solubilization. By indirect isolation from NA, SCA, Jensen, and YEMA, 2, 3, 1, and 3 isolates of RRoEB and 4, 3, 1, and 3 isolates of RRzSB showed the capability as phosphate solubilizer. Although the highest colony diversity of PSB was obtained from direct isolation, however the highest PSI was yielded from indirect isolation, namely isolates J1R1 (3.53) and Y1S1 (2.48). The highest PSI from direct isolation was obtained by P1R5 (1.90) and P1S1 (1.51).

Published: June 2024

AbstractExposure to plastic in the soil causes the formation of plastic debris, which breaks down into microplastics (plastic measuring <5 mm). Microplastic pollution that occurs in ecosystems has the potential to enter the human food chain and is considered a severe threat to human health. One solution to overcome the problem of microplastic pollution is to use indigenous bacteria as natural microplastic decomposing agents. This research uses an exploratory descriptive method with soil samples from the landfill followed isolation and identify the potential of indigenous bacteria from Putri Cempo landfill to degrading microplastics. Based on the research results, two isolates could degrade microplastics, namely separates CP1 and CP2. Isolate CP1 was proven to lessen microplastics by 2.43% and isolate CP2 by 1.15%. Bacterial isolates CP1 and CP2 have the same morphological characteristics. Bacterial isolates CP1 and CP2 are gram-negative bacteria, round, cream in color, with smooth edges, shiny elevations, and bacillary cell shape. In the oxidase and O/F tests, isolate CP1 had positive results, while CP2 had negative values. Bacteria CP1 grows optimally at 37°C, pH five, while CP2 at a temperature of 27°C, pH nine, and both are tolerant to NaCl at a level of 4%.

Abstract
Lingnan, Arab, and Kedu chickens are the main breeds used as parental lines to develop Maron chickens. The genetic distance between Maron chicken parental lines is critical to achieving heterosis. D-Loop Mitochondria’s Hypervariable 1 (HV1) region is a genetic distance marker. This study aims to determine the genetic distance between the Maron chicken parental lines using the mitochondria HV1 marker. A total of 73 blood samples were collected from Lingnan, Arab, and Kedu chicken. In this study, Polymerase Chain Reaction was employed to amplify D-loop HV1 region in mitochondria, followed by DNA sequencing. A maximum likelihood (ML) analysis then used to generate phylogenetic reconstruction. As a result, eight haplotypes were identified, 21 being the highest, and 1 belonging to the lowest. All pairwise comparisons reveal significant population differences (Fst = 0.67 - 0.962). PCA analysis revealed that Lingnan, Arab, and Kedu populations are different from one to another. Then it is concluded that Lingnan, Arab, and Kedu chickens have a significant genetic distance, which can be used to guide the breeding process of Maron chicken.

Abstract
Chaya leaves (Cnidoscolus aconitifolius) contain many nutrients and phytochemicals expected to reduce ruminants’ methane emissions. This study aims to determine the nutritional quality, phytochemical content and potential inhibitory power of Chaya leaf extract against the growth of rumen fluid methanogen bacteria. The methods used to determine nutrient content were proximate and fibre analysis. The phytochemical content tested were total phenols, tannins and flavonoids. Anti-methanogen test through inhibitory power using liquid culture selective media for methanogens. The results showed that Chaya leaves are a source of fibre feed, which also contains high crude protein (23 - 29%). The highest total phenol and tannin content in ethanol extract of Chaya leaves is 8.62 mg/g and 31.34 ppm, respectively. In contrast, ethyl acetate extract’s highest total flavonoid content is 13.96 mg/g. The highest potential inhibitory power against methanogen bacteria was shown by ethanol extract (50 mg/mL), causing inhibition of 44.56%. This study concludes that Chaya leaves have the potential to be used as ruminant animal feed and as a suppressor of methanogen bacteria, and further tests are recommended for methane gas production in vitro.

Abstract
Tropical riparian wetland known as non-tidal lowland is potential land for agriculture, especially for vegetable cultivation such as red chili pepper (Capsicum annum L.). Transitional period (dry to rainy season) has a chance for red chili pepper cultivation in the field (at low tide conditions), but has risk of experiencing dynamic water table to waterlogging in early rainy season. The aim of this research was to determine the effects of physiological traits of red chili pepper exposure on short-term (4 days) waterlogging. This study was done at the Tropical Crop Science Laboratory, Kagoshima University, Japan. The experiment was designed as a completely randomized factorial design. The first factor was control/field capacity and waterlogging (entire growing media was submerged). The second factor was chili variety, consisting of Laris and Romario. Treatments began 14 days after transplanting, lasted four days, then followed by seven days of recovery. The results of this study showed that there were changes in photosynthetic characters between before waterlogging, after waterlogging and after recovery time, between control and waterlogging, and also between Laris and Romario. Photosynthetic and transpiration rates decreased sharply under waterlogging in after waterlogging, but increased in after recovery period on Laris, opposite on Romario. Changes occur were associated with the decline in stomatal conductance and chlorophyll fluorescence as a response to waterlogging stress. Laris as a resistant variety has the ability to recover under short-term stress conditions, so it needs to be further developed for cultivation in tropical riparian wetlands.

Published: June 2024

Abstract
Intestinal bacterial composition is one of the markers that can be observed in poultry under heat-stress conditions. This study evaluated the effects of dietary betaine on the intestinal bacterial composition of growing pullets reared in a tropical climate. The ninety-six Lohmann laying hens aged three weeks old were distributed into two dietary groups, each comprising six replicates of eight birds. This experiment used PAR-DOC (Japfa Comfeed ©) as basal diet (T0) and basal diet with 1.2g/kg betaine supplementation (T1). The next-generation sequencing method of the 16S rRNA gene region V3–V4 was applied to explore the taxonomy profile. Bacteria from the genus Faecalibacterium, Akkermansia, Desulfovibrio, and Lachnospiraceae UCG-002 were reported as markers in the heat stress condition. A t-test was applied using R software to evaluate the effect of each treatment. The relative abundance from the genus Akkermansia as a marker heat stress response in T1 treatment showed significantly lower than T0 (p<0.05). Based on this result, we concluded that the lower population of the genus Akkermansia indicated that betaine supplementation could alleviate heat stress conditions in growing pullets.

Abstract
This paper takes part in the research on the response of affected farmers to National Strategic Projects. This article reviews the information exposure. The present study aims to examine how farmers assess the frequency of exposure, the credibility of information sources, and the strength of reference groups in constructing the Solo-Yogyakarta toll road in Klaten Regency. The results showed the frequency of information from the government and the largest share of farmers rated as “sometimes”. Meanwhile, the frequency of information from offline (neighbors) and online (media) sources were both considered “never”. Meanwhile, in terms of the credibility (trust and expertise) of information sources, the majority of affected farmers admitted their trust in the government. In terms of the trustworthiness of offline and online reference groups, most farmers doubted the information provided by the offline reference groups and did not trust the information from the online reference groups. Smallholder farmers considered the frequency of information exposure on the land use conversion policy for toll road construction from the government required improvement. However, when compared to the information from neighbors and media, the affected farmers admitted their trust in the official information from the government.

Published: June 2024

AbstractSoybean production in Indonesia needs to supply for domestic needs sufficiently. One of the things that influence is the reduction of soybean harvest areas in Indonesia. One of the solutions to the problem is through extensification by utilizing land under shade, which is called an agroforestry system. Agroforestry systems will change intercrop environmental conditions such as reducing light intensity, temperature and increasing humidity. The condition will affect disease development in soybean plants, especially bacterial pustule disease caused byXanthomonas axonopodispv. Glycines.X. axonopodisbacteria can reduce soybean productivity by up to 57.61% in susceptible hosts and favorable environmental conditions. In this research, observations were made regarding the symptoms and incidence of bacterial pustules infection on seven varieties under the shade of mahogany. The varieties used were Anjasmoro, Argomulyo, Dena-1, Dena-2, Denasa-1, Denasa-2, and Devon-1. The research was conducted for three months at KHDTK (Kawasan Hutan dengan Tujuan Khusus) Alas Bromo, Karanganyar, Central Java, Indonesia. The research showed that the lowest incidence of bacterial pustule occurred in the Anjasmoro varieties, with an incidence value of 0%. In comparison, the highest incidence of attacks occurred on the Denasa-1 variety, up to 23.3%.
