Abstract

The research was conducted to determine the quality of the waters of the Ciwaka Reservoir, Serang City, Banten, based on the content of chlorophyll-a and the presence of phytoplankton. The relationship between the chlorophyll-a content and the presence of phytoplankton with the physical-chemical parameters of the waters was also being analyzed. Thus the results from the study were used as content for learning media education research. This research was conducted from February-July 2021, in Ciwaka Reservoir, Serang City, Banten. A sampling of water at three stations was carried out using the purposive sampling method. Chlorophyll-a analysis was carried out using spectrophotometric methods. The results of chlorophyll-a analyze in each station ranged from 7,458 g/L – 34,352 g/L. Ciwaka Reservoir is included in the category of waters that are eutrophic (polluted) due to high nutrient levels. The water quality of Ciwaka Reservoir is still in good condition according to the designation of class 2 water quality standards in PP No. 82 of 2001. The content of chlorophyll-a and the presence of phytoplankton (abundance, diversity, and dominance) only has a weakness with the brightness (r = 0.000). Phytoplankton diversity was strongly correlated with temperature (r = 0.994). Phytoplankton dominance was strongly related to DO (r = 0.998) and BOD (r = 0.998).

Abstract

Polymerase Chain Reaction (PCR) is a technique that is applied to detect and test the presence of genetic material from pathogenic fungi. This method was further developed because it has a high sensitivity compared to the culture method in detecting the presence of pathogenic fungi. To perform sensitive, specific and reliable PCR-based assays, the availability of pure DNA as well as an easy-to-perform DNA extraction protocol is essential. Currently, existing protocols for DNA extraction generally require specialized kits and with the addition of enzymes. Therefore, this study was conducted to compare the quantity and quality of Aspergillus niger DNA isolation with three different methods. The stages of the research carried out included pure A. niger culture and total DNA isolation using three methods, namely the protocol according to the Wizard® Genomic DNA Purification Kit (P1) instructions, Modified Wizard® Genomic DNA Purification Kit (P2) and Monarch Genomic DNA Purification Kit NEB (P3). The results of the evaluation of DNA isolation using a spectrophotometer at a wavelength of A260/280 nm showed a ratio of 1.4, 1.8, and 1.7 at P1 and P2, and P3 respectively. The quantity obtained ranged from 210 to 305 ng/µL. The total DNA results obtained were then used for PCR testing of ITS ribosomal DNA fragments using ITS1 and ITS4 primers. Electrophorosis observation of PCR results showed that all samples produced bands with a length of 500 bp. The results of DNA isolation in the P1 method did not show bands on the agarose gel, but could be seen in the PCR product. Methods P2 and P3 showed DNA that had good quality and quality. The P2 and P3 methods use a cell destruction technique with liquid nitrogen and a combination of addition of proteinase K. The obtained protocol is expected to provide fast and good method information in the isolation of total DNA from A. niger. Keyword: Aspergillus niger, total DNA isolation, ITS1, ITS4

Abstract

The downstream area of Unda River Watershed located in Klungkung Regency has experienced succession due to the eruption of Mount Agung in 1963. The ecosystem in the downstream area of the Unda River also experienced anthropogenic succession due to human activities which affected the plant species that composing the vegetation. This study aims to observe the floristic composition of vegetation in the downstream area of the Unda River. The research was conducted by exploration method in three types of ecosystems: lowland forest, marshes, and beaches. The results show the floristic composition in the downstream of Unda River composed by 163 plant species, classified in 48 families and 128 genera. The major growth form is small herb (47 species), grass (35 species), and tree (31 species). Fabaceae is the plant family with the most abundant species, followed by Poaceae and Cyperaceae. Based on the research zones, the lowland forest has the highest number of plant species (120 species), while the beach zone has the lowest (82 species). The ecosystem stability in the downstream area of Unda River can be disturbed by the existence of invasive species, such as Eichhornia crassipes, Chromolaena odorata, Lantana camara, Ipomoea carnea, Vachellia farnesiana, and Typha angustifolia.

Abstract

Acrylamide is a contaminant compound found in several types of food containing carbohydrates and processed food through frying or roasting at high temperatures. Acrylamide compounds could cause the formation of oxidative stress which could lead to neurotoxicity. This oxidative stress could be minimized by administering the antioxidant vitamin C. This study was conducted to determine the mice cerebral cortex histology, the mice cerebellum histology induced by acrylamide and vitamin C supplementation, and the most effective dose as a neuroprotector. This study used a completely randomized design (CRD) with 4 groups, namely K + (acrylamide 12.5 mg / kg BW); K- (NaCl 0.9%); P1 (vitamin C dose of 0.26 mg/animal /day + acrylamide dose of 12.5 mg/kg BW); and P2 ((vitamin C dose of 0.52 mg/animal/day + acrylamide dose of 12.5 mg / kg BW) and 6 repetitions so that the number of mice used was 24. The acrylamide and vitamin C solutions were administered orally, and acrylamide given for 20 days, while vitamin C was given 3 days before acrylamide induction until day 20. Mice were dissected at day 21, brain organs were collected for histological preparations by the paraffin method and Hematoxylin-Eosin staining. The qualitative data obtained were analyzed by One Way ANOVA and continued with the Duncan test. The parameters observed were necrosis in pyramid cells and glial cells. The results showed that vitamin C at dose of 0.52 mg/animal/day significantly repaired the damage in pyramid cells and glial cells induced by acrylamide.

Abstract

Limbah berupa kulit dan biji yang berasal dari industri pengolahan carica Dieng (Vasconcellea pubescens) dapat menjadi permasalahan lingkungan apabila tidak tertangani dengan baik . Larva BSF (Hermetia illucens) sebagai agen biokonversi diharapkan mampu menjadi solusi untuk permasalahan tersebut. Penelitian dilakukan secara eksperimental dengan menggunakan rancangan acak lengkap (RAL) dengan 6 perlakuan dan 4 ulangan meliputi perlakuan kontrol, P1 = 100% kulit, P2 = 75% kulit + 25% biji, P3 = 50% kulit + 50% biji, P4 = 25% kulit + 75% biji, dan P5 = 100% biji. Waktu pengamatan penelitian dilakukan selama 21 hari. Parameter utama yang diamati adalah nilai konsumsi pakan dan indeks pengurangan limbah (WRI), sedangkan parameter pendukung berupa biomassa larva, diameter kapsul kepala dan tingkat kelulusan hidup (survival rate). Data yang diperoleh dianalisis menggunakan ANOVA dengan tingkat kesalahan 5%, dan apabila perlakuan berpengaruh nyata, dilanjutkan dengan uji DMRT dengan tingkat kesalahan 5%. Hasil penelitian dengan jenis pakan yang bervariasi menunjukkan nilai konsumsi pakan tercerna oleh larva BSF berkisar antara 60,42% - 81,26%. Sedangkan untuk nilai indeks pengurangan limbah (WRI) berkisar antara 2,82% - 3,73%. Nilai reduksi limbah lebih dari 50% menunjukkan adanya efektivitas larva BSF dalam mendegradasi limbah organik. Dengan demikian penggunaan jenis pakan berupa pakan penggunaan larva BSF efektif dalam mereduksi limbah pengolahan carica Dieng (V. pubescens).
