Abstract

Flies are insects that live close to the human environment. Flies around the settlement were many and carry a variety of diseases that can danger the public health. Research purpose is to determine the relative abundance, frequency and dominance of flies in several traditional markets at Martapura District. This research was conducted in five traditional markets, namely Sejumput market, Batuah market, Sekumpul market, Permata market, and Kuliner market in April to May 2020. Flies were collected using a sweep net by swinging it around the landfills. The collected flies were then identified using identification keys. Results showed there were four species of flies in research location, that are Musca domestica, M. cinducens, Chrysomya megacephala, and C. rufifacies. The relative abundance, species frequency and species dominance signified that the capturing of M. domestica flies is the highest. Furthermore, Batuah market location have the highest amount of relative abundance, species frequency, and species dominance of flies compared to other locations. This research is useful as preliminary information in determining the potential of flies as a vector of disease transmission in an environment. Keyword: relative abundance, frequency, dominance, type of flies, traditional market

Abstract

Kerang merupakan salah satu sumberdaya laut di Pulau Serangan yang telah lama dimanfaatkan oleh masyarakat sebagai sumber bahan pangan bergizi dan bernilai ekonomis. Penelitian ini bertujuan untuk menganalisis kandungan logam berat timbal (Pb) pada kerang yang dimanfaatkan oleh masyarakat di kawasan perairan Serangan. Sampel kerang diperoleh dari hasil tangkapan masyarakat di tiga lokasi dan tempat pengumpul kerang. Metode yang digunakan adalah preparasi pengabuan basah dan dianalisis dengan alat ICPE (Inductedvely coupled plasma emission). Hasil penelitian menunjukkan kandungan logam berat timbal (Pb) pada kerang bernilai ekonomi (Marcia opima, Marcia hiantina, Perna sp.) yang ditangkap oleh nelayan melebihi ambang batas BPOM (2,093 - 2,571 mg/kg). Namun proses pendedahan dengan perendaman 24 jam menurunkan kandungan timbal (Pb) di bawah ambang batas (0,387 - 0,971 mg/kg).

Abstract

Warna menjadi indikator keindahan pada ikan hias, semakin cerah warna ikan maka akan semakin menarik dan harga jualnya pun akan semakin tinggi. Namun selama pemeliharaan ikan hias, warna sering menjadi kusam, kualitas warna menurun sehingga ikan hias tidak menarik lagi. Untuk itu perlu usaha untuk mempertahankan dan meningkatkan kualitas warna ikan, salah satunya dengan memberi pakan yang mengandung sumber karotenoid. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian tepung udang rebon terhadap kualitas warna pada ikan cupang. Penelitian ini dilakukan dengan metodeeksperimen yang disusun dalam rancangan acak lengkap (RAL) terdiri dari lima perlakuan dan empat kali ulangan selama 40 hari perlakuan.Perlakuan yaitu pemberian pakan tanpa penambahan tepung udang rebon (kontrol) dan pemberian pakan dengan penambahan tepung udang rebon 5%, 10%, 15%, dan 20%. Tingkat perubahan warna diamati setiap 10 hari menggunakan Toca Colour Finder memperlihatkan pemberian pakan dengan penambahan tepung udang rebon berbeda nyata pada taraf 5% terhadap tingkat perubahan warna baik pada sirip anal maupun sirip ekor ikan cupang. Pakan dengan penambahan tepung udang rebon 15-20% memberikan pengaruh yang baik dalam meningkatkan kualitas warna ikan cupang.

Abstract

Acacia decurrens, originally from Australia, is a woody plant that has become a concern in the erupted areas of Merapi volcano in 2006. The purpose of this study was to quantitatively describe the ecology of Acacia decurrens, and its invasive potential. Vegetation analysis was carried out in four areas of Mount Merapi National Park (TNGM), namely Kalikuning, Kaliadem, Plawangan and Pranajiwa. Ordination using the Non Metric Multidimensional Scaling (NMDS) method and Canonical Correspondence (CCA) and Spearman's bivariate correlation were carried out in data analysis. The results of NMDS analysis (2D stress = 0.14) showed that open areas due to eruption in Kaliadem are now dominated by A. decurrens. The results of the analysis also showed a significant negative correlation (Spearman rho = 0.6) between the abundance of A. decurrens and the level of species diversity in the sampling location. From the results of CCA, A. decurrens in the seedling stage appeared to coexist with other types of ground cover such as Alangium javanicum and Araliaceae. But in the tree phase, this species tended to form pure stands and only occasionally appeared to live side by side with other types of Fabaceae such as Albizia lopantha. Tree-level A. decurrens seemed to prefer sites with lower pH levels while A. decurrens seedling levels were more commonly found in sites with higher pH. Acacia decurrens have the potential to become a weed in TNGM due to its dominant distribution and tendency to decrease the level of species diversity in TNGM.

Abstract

Blood is one of the most important component of human body. In a case of crime, blood found at the site can be used as an evidence to track back the victim or the person who did such criminal. The main objective of this research were to investigate the time needed for the convertion of blood types and to identify bacterial species with capability to convert blood types. This research was conducted at Forensic Laboratory and Microbiology Laboratory, Faculty of Mathematics and Science, Udayana University. The methods used for detection of blood types and identification of Bacterias were elution method and vitex method, respectively. The results showed that blood type A on iron surface and ceramic media was changed into fake O type on day 25, while blood types of B and AB on ironic media were converted into fake type of O after 30 days of exposure. Two species bacteria (Rhizobium radiobacter and Serratia ficaria) with ability to convert blood type were identified in this research. Key Word: Rhizobium radiobacter, Serratia ficaria, changes of blood types
