The Sigolo-golo natural tourism area is located in the Wonosalam district, Jombang. The environment in this area is still relatively well preserved because it has a variety of vegetation and habitats. There is very little information on the community structure of butterflies (Papilionoidea) in this area, so this research is needed to find the community structure of butterflies in Sigolo-golo tourism. The method used in this research is a visual encounter survey combined with the transect method, which is to carry out direct counts of species and individuals of butterflies that are often found. The research locations were divided based on different habitat types, namely plantations, forests, and riverbanks. This study found 43 species with 358 individuals from five families. The results of the data analysis show that the diversity index value at each location is in the high category. The diversity and revealing butterflies at each location explain why the community structure in Sigolo-golo tourism is still stable and well maintained.

Seven Streptomyces strains from chili farm soil, including Strep-1, Strep-2, Strep-4, Strep-5, Strep-6, Strep-8, and Strep-10, were screened for their antifungal activities against Fusarium sp. of chili's root rot disease. The results showed that Streptomyces sp. Strep-4 and Streptomyces sp. Strep-8 performed potential abilities to control the pathogenic Fusarium of which means of antifungal efficacies were 43,88 ± 3,21% and 51,8 ± 2,54%, in turn. Extensive researches on the effects of inoculum factors on antifungal activity of Streptomyces sp. Strep-8 resulted that this strain spontaneously synthesized the antifungal compounds to control Fusarium in the culture condition with pH 7, 40oC of culture temperature, and 7 days of culture time. The results proved that Streptomyces sp. Strep-8 with its thermophilic ability not only provided significant inhibitory activity against pathogenic Fusarium sp. in vitro also promised to be a potential biological control agent to eliminate this fungus on fields. Moreover, using Streptomyces sp. Strep-8 as a biological control agent helps reduce the use of fungicides which contributes to boosting the sustainability of agricultural ecosystems worldwide.

The Fall armyworm (FAW) Spodoptera frugiperda, native to the Americas, is an important invasive and polyphagous pest threatening cereal production. Abiotic and biotic factors, including climatic uncertainty and insect pests like S. frugiperda, pose threats. Detected in East Africa in 2016 and reported in Nawalpur, Nepal, on May 9, 2019, FAW has led to a 34% decline in maize yields. Studying FAW's biology and morphometrics is crucial for understanding its habitat and ecology, essential prerequisites for adopting integrated management strategies. Biological parameters such as incubation period, larval and pupal duration, pre-oviposition and, oviposition periods, male and female adult longevity, larval and pupal mortality, sex ratio (male: female), and morphometrics of egg, larvae, pupa, and adult were measured. The incubation period (2-3 days), larval and pupal periods (13-18 and 9-12 days) with overall life duration (31-45 days) were recorded in maize. Head capsule width of the first, second, third, fourth, fifth, and sixth instar were recorded as 0.52±0.05, 0.73±0.05, 1.1±0.05, 1.74±0.12, 2.04±0.15, and 2.91±0.23 mm respectively. Mean body length of different larval instars were recorded as 3.33±0.26, 6.92±1.07, 13.11±1.45, 16.82±1.57, 28.68±1.75, and 34.56±1.99 mm for the first, second, third, fourth, fifth, and sixth instar respectively.

Abstract The family Burseraceae comprises a total of 18 genera and 540 species. Boswellia dalzielii is a botanical species commonly employed in tropical and subtropical regions for its therapeutic properties, serving as a remedy for a diverse range of health conditions. The taxonomic identification and chemical composition of B. dalzielii in northern Nigeria have not been extensively documented in scientific literature, despite the recognized medicinal efficacy of this plant species. The soxhlet extraction method was employed to extract ethanol, methanol, and aqueous crude from the leaves. Subsequently, the extracted samples were subjected to analysis using gas chromatography combined with mass spectrometry. Fourier Transform Infrared spectroscopy (FTIR) was employed for the purpose of functional group identification in the crude extract. There was clear and noticeable distinction between the species under consideration on the X axis of principal component (PC) 1. The methanol and aqueous chemicals that were extracted from B. dalzielii showed a higher degree of similarity and were found to cluster together on the left side of the PC1 axis. PC2 did not indicate a clear distinction of the extract. The ethanol extract included 15 different chemicals, the methanol extract contained 12 different chemicals, and the aqueous extract contained 11 different chemicals.

This study aims to determine and analyze the relationship of organic carbon in sediments with the growth rate of seagrass Enhalus acoroides and Thalassia hemprichii. This research was conducted on Langkai Island, Makassar City, with three points, namely near the coast, in the middle and near the coral reefs. The research phase began with marking the seagrass E. acoroides and T. hemprichii in the field, then measuring the growth rate of the seagrass, followed by a sieving process to determine the texture of the sediment, and burning to determine the organic carbon content of the sediment. The results showed that differences in sediment organic carbon showed a weak correaltion and insignificant. The differences in the growth rates of seagrass E. acoroides and T. hemprichii based on point were not significant. The relationship between organic carbon and sediment texture has a weak correlation and insignificant. Similarly, the effect of organic carbon on the growth rate of seagrass E. acoroides and T. hemprichii also showed a weak correlation and insignificant.

Tempeh and tofu are widely consumed by Indonesians and easily made using simple tools and method, thus numerous home industries producing are emerging. However, soybean processing in these industries produces high volume of wastewater. This study provides a simple wastewater treatment instrument design that could be used by soybean-based home industries by applying a series of physical, chemical, and biological treatment. Physical treatment was performed by filtration, chemical by addition of alum salts, while biological treatment was done by supplementing with lactic acid bacteria (LAB) from leftover container of fermented milk. Wastewater was recorded by its parameters (temperature, pH, dissolved oxygen/DO, biological oxygen demand/BOD, turbidity) at every phase of treatment after incubation for two various of periods; 1 hour and 5 days. Results showed that wastewater treated using instrument design had changes in all of its parameters observed during the course of treatment. Wastewater treated in all phase of instrument incubated for 1 hour showed parameters approaching wastewater quality standards, thus it was safer to be disposed to environment compared to wastewater incubated for 5 days. Wastewater treatment as designed in the current study can be applied by soybean-based home industries with short incubation time to remediate wastewater produced during soybean processing before disposal.
