Abstract

The study employed the insect net method to sample insects from the Bangek River. Primary and secondary data were collected for analysis. The research was conducted at Bangek River, Lubuk Minturun District, Padang City, West Sumatra Province. Insect sampling involved a single event using an insect net within the administrative area of Lubuk Minturun. A total of 35 insects were captured from the Bangek River, comprising 5 species from the Lepidoptera order, 28 from the Odonata order, and 1 species each from the Hemiptera and Orthoptera orders.

Abstract

Cultivation of horticultural crops especially fruits, has long been practiced in Indonesia. Citrus plants are one of the main fruit commodities developed in Indonesia. Increased citrus production is inseparable from challenges, especially in controlling harmful pest attacks. Bactrocera fruit fly has attracted worldwide attention because of its ability to attack more than a hundred horticultural crops and cause crop failure. Various ways have been done to control Bactrocera, such as protecting the fruit with wrapping and even the use of synthetic insecticides that cause many losses. To overcome this, innovations are needed using biological control. Entomopathogenic fungi are potential candidates for bioinsecticides. This study aims to isolate and identify entomopathogenic fungi from Bactrocera dorsalis from citrus plants. The entomopathogenic fungus isolation method uses the moist chamber method. Then the fungal isolates will be identified macroscopically and microscopically. The isolation results show that five types of fungi are identified from the body of Bactrocera dorsalis. The five fungi can be used as candidates for entomopathogenic fungi.

Abstract

Pest attacks caused by fruit flies (Bactrocera sp.) can cause damage to fruit quality. Damage can become more severe due to secondary infection by bacteria or fungi which can cause fruit to rot. This research was conducted to determine the effectiveness and morphological changes caused by the fungus Nigrospora sp. and Penicillium sp. on the mortality of Bactrocera sp. This research was conducted using a Randomized Block Design (RBD) with two factors: the type of entomopathogenic fungi and the density of spores. Entomopathogenic fungi isolates were obtained from the isolation of entomopathogenic fungi from fruit flies (Bactrocera sp.) from previous studies. The spore density used for each fungus was 105, 106, and 107 spores/mL. Each treatment unit used 5 Bactrocera sp. adults with 3 repetitions. In the isolates of Nigrospora sp. they have resulted in mortality at a spore density of 105 spores/mL of 86%, a density of 106 spores/mL of 93%, and a density of 107 spores/mL of 100%. In the isolates of Penicillium sp. all treatments resulted in 100% mortality.

Abstract

Nutrition in pregnancy is needed for fetal growth and development. Insufficient nutrition has the risk of causing Chronic Energy Deficiency (CED). The CED rate among pregnant women in Indonesia is 17.3% and in Lampung Province it is 13.6%. Nutritional status is influenced by nutritional intake and helminthiasis infection. Apart from that, there are other factors such as social determinants of health, namely economics, education, employment and age. This research uses a cross-sectional research design. The research sample was 86 pregnant women. Data collection was carried out using a questionnaire, measurement of Upper Arm Circumference (MUAC), and examination of feces using the formol ether sedimentation method. Bivariate analysis used chi square, Fisher, and Mann Whitney. The results of the study showed that there was a significant relationship between helminthiasis (p = 0.009), education (p = 0.023), and per capita income (p < 0.001) with the nutritional status of pregnant women. Meanwhile, for other variables (knowledge about helminthiasis, preventive behavior, age, and occupation) there was no significant relationship (p > 0.05). Helminthiasis is related to the nutritional status of pregnant women, so active screening is needed for the incidence of helminthiasis in pregnant women in the working area of the Karang Anyar Community Health Center, Jati Agung District, South Lampung Regency.

Abstract

River pollution is a major problem in the water quality crisis due to certain factors, including human activities around the river ecosystem which are strongly suspected to be the main cause of the problem. The purpose of this study was to determine the diversity and abundance of macrozoobenthos and the level of water pollution in the Way Semah Pesawaran River. The research was conducted using three indicators of water quality: biological indicators in the form of macrozoobenthos, physical indicators in the form of temperature and brightness, and chemical indicators in the form of pH, DO, and BOD. Sampling was carried out at 3 stations with two points, namely the right bank and left bank points at each station. The method of determining the location and data collection using the purposive sampling method. Based on the results of the analysis of abundance, diversity, uniformity and dominance of macrozoobenthos obtained the ecosystem of Way Semah River waters showed mild to moderate polluted conditions with a range of 1.21 - 1.87

Abstract

Water pollution refers to the introduction of living organisms, substances, or other components by human activities that can degrade water quality or cause environmental harm. Gonad maturity level indicates the stage of readiness of prospective broodstock for the spawning process, assessed through visual and histological methods. This study aimed to assess water quality in the Way Awi River based on fish community structure and to evaluate the impact of sewage discharge on fish gonad maturity levels in Bandar Lampung's Way Awi River. Conducted between November and December 2023, this research sampled five points along the Way Awi River. Chemical analysis included pH, BOD, COD, and DO, while physical parameters such as temperature and TSS (Total Suspended Solids) were also analyzed. The findings indicate that the Way Awi River is moderately polluted, with no significant impact on the community structure, although there is a noticeable decrease in fish numbers from upstream to downstream. This study underscores the importance of understanding the risks associated with continuous disposal of waste into rivers.

Abstract

Staining is an important stage in preparing microscopic preparations so that the histological structure can be observed clearly. Hematoxylin-Eosin is the most widely used dye. Unfortunately, eosin is a synthetic chemical compound that is carcinogenic. To reduce the health and environmental impacts of eosin compounds, it is important to look for alternative dyes from natural ingredients. Hibiscus (Hibiscus rosa-sinensis L.) is a plant known to contain anthocyanins which can be used as eosin substitutes. This study aims to determine the potential of hibiscus extract as a substitute for eosin in histological staining. In this study, unstained liver tissue preparations from mice (Mus musculus) were used. Hibiscus extract dye was compared with eosin as a control. The color quality of the tissue preparations was used as an experimental parameter. The results of the microscopic assessment showed that liver tissue stained with Hibiscus extract at concentrations of 60% and 80% was less good than eosin. However, because tissue can stain reddish, hibiscus extract has the potential to be used as an eosin substitute. The right extraction method may be able to produce intact anthocyanin so that it can color the tissue optimally.
