Penelitian ini bertujuan untuk menganalisis efek A. antiquata terhadap kuantitas dan kualitas spermatozoa Mus musculus. Penelitian ini merupakan penelitian eksperimental murni dengan rancangan acak lengkap pola faktorial. Faktor pertama adalah kondisi kerang, yakni mentah dan kukus, dan faktor kedua adalah konsentrasi 0 g/mL, 75 g/100 mL, dan 100 g/100 mL. M. musculus yang digunakan sebanyak 25 ekor, terdiri dari lima perlakuan dengan masing-masing lima kali ulangan. Parameter yang diamati adalah konsentrasi (kuantitas), motilitas, dan morfologi (kualitas) spermatozoa. Data dianalisis menggunakan uji Kruskal-Wallis dan uji lanjut Duncan. Hasil penelitian menunjukkan bahwa A. antiquata berpengaruh nyata terhadap konsentrasi dan motilitas spermatozoa, sedangkan morfologi tidak memberikan pengaruh yang nyata. Kondisi kerang mentah dengan konsentrasi 100 g/100 mL memberikan efek rata-rata terendah terhadap konsentrasi dan motilitas spermatozoa, sementara kerang kukus dengan konsentrasi 75 g/100 mL meningkatkan rata-rata konsentrasi dan motilitas spermatozoa tertinggi. Penelitian ini memberi kesimpulan bahwa mengonsumsi kerang kukus lebih baik untuk meningkatkan konsentrasi dan motilitas spermatozoa dibandingkan dalam kondisi mentah. Peningkatan dosis kerang kukus tidak linier terhadap respon kuantitas dan kualitas spermatozoa.Kata kunci: Anadara antiquata; Konsentrasi spermatozoa; Motilitas; Morfologi; Mus musculusAbstract Shellfish (Anadara antiquata) was one of the foods that contained high nutrients such as protein, fat, vitamins, and minerals that had the potential to improve and increase the quality of sperm. The study aims to analyze the effect of the shellfish on the quantity and quality of Mus musculus sperm. This study was a purely experimental study with a completely randomized factorial pattern; the first factor was the condition of shellfish which was raw and steamed, and the second factor was concentrations of 0 g/mL, 75 g/100 mL and 100 g/100 mL.

Karena bersifat praktis, berbagai jenis kantong plastik sebagai kemasan selalu menjadi pilihan dalam aktivitas masyarakat. Akan tetapi, sifat plastik yang sulit terdegradasi pada lingkungan alami menimbulkan permasalahan sebagai salah satu sumber pencemaran. Penelitian ini bertujuan untuk mengetahui potensi mikroorganisme tanah yang diisolasi dari sampah Tempat Pembuangan Akhir (TPA) Antang Makassar dalam mendegradasi kantong plastik LDPE hitam dan putih. Metode biodegradasi plastik yang digunakan adalah kolom Winogradsky dengan menggunakan kolom kaca 1.000 mL yang berisi 500 gram tanah sampah TPA Antang dan plastik uji LDPE warna hitam dan putih. Kemudian dilakukan pengukuran persentase degradasi selama 3 bulan masa inkubasi dengan waktu panen selama 3 minggu sekali. Hasil penelitian menunjukkan bahwa terdapat 6 isolat dalam kolom Winogradsky mampu mendegradasi plastik LDPE hitam sebesar 3,5% dan 6 isolat lainnya mampu mendegradasi plastik LDPE putih sebesar 2%. Selanjutnya, isolat ini dapat digunakan sebagai agen biodegradasi plastik di TPA Antang Makassar.Abstract The use of plastic bags is almost unavoidable in industries, including the food, clothing, transportation, construction, medical, and recreational industries. Various types of plastic bags have been used in various types of packaging, because of the value of practicality. However, the difficulties in the degradation process become a problem as a pollution source in the environment. The purpose of this study was to determine the potential of soil microbes isolated in Antang landfill, Makassar, in degrading black and white plastics of LDPE. The biodegradation method used was the Winogradsky column using a 1,000 mL glass column containing 500 grams of Antang landfill soil and using black and white LDPE as well. The percentage of degradation was measured for three months incubation period with harvest time for three weeks. The results showed that the inoculum in Winogradsky column was able to degrade the black plastic by 3.5% and the white plastic by 2%. The results of macroscopic and microscopic characterization showed that six isolates were degrading the black plastic and six isolates were degrading the white plastic, with different characteristics. Furthermore, this isolate can be utilized as a biodegradation agent for plastic in the Antang landfill.","PeriodicalId":31088,"journal":{"name":"AlKauniyah Jurnal Biologi","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84790035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sementara itu, nilai rata-rata keseragaman sianobakteri adalah 0,52, dengan keseragaman tertinggi berada di stasiun 3 dengan nilai 0,71 dan terendah berada di stasiun 2 dengan nilai 0,36. Hasil pengukuran faktor abiotik di Sungai Kelingi adalah: suhu 25 °C, oksigen terlarut 43,63 mg/L, keasaman 7,29 dan kecerahan 72,47 cm. Dapat disimpulkan bahwa keanekaragaman sianobakteri di Sungai Kelingi Kota Lubuklinggau tergolong ke dalam kriteria sedang. Sianobakteri yang ditemukan Homoeothrix sp., Lyngbya sp., Nostoc sp., Oscilatoria limosa, dan Spirulina sp. Adanya penelitian ini dapat memberikan gambaran tentang sianobakteri di Sungai Kelingi, Kota Lubuklinggau.Abstract Kelingi River in Lubuklinggau City has polluted waters. Up to present, there is no studies have found regarding cyanobacteria in Kelingi River. The purpose of this research was to analyze the diversity of cyanobacteria and their abiotic factors. The results showed that the cyanobacteria found were consisting of 1 class, 2 orders, 3 families, 5 genera, and 5 species. The average value of cyanobacterial diversity was  1.41, with highest diversity being at station 3 by 1.27 and the lowest being at station 2 by 0.66. The average dominance of cyanobacteria was 0.43, with the highest dominance being at station 2 by 0.53 and the lowest being at station 3 by 0.30. The average value of uniformity was 0.52, with the highest uniformity being at station 3 by 0.71 and the lowest being at station 2 by 0.36. The results on the measurement of abiotic factors in the Kelingi River were: temperature 25°C, dissolved oxygen 43.63 mg/L, acidity 7.29 and brightness 72.47 cm. It was concluded that the diversity  of cyanobacteria in Kelingi River belongs to the criteria of being moderate. The cyanobacteria found were Homoeothrix sp., Lyngbya sp., Nostoc sp., Oscilatoria limosa, and Spirulina sp. This study provides an illustration of cyanobacterial diversity in the Kelingi River.","PeriodicalId":31088,"journal":{"name":"AlKauniyah Jurnal Biologi","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81818934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
