Gambaran Siklus Estrus Tikus Rattus Norvegicus Terpapar Asap Rokok Setelah Diterapi Ekstrak Etanol Rumput Kebar (Biophytum Petersianum Klotzsch)

Rumput Kebar merupakan tanaman yang mengandung fitoestrogen yang memiliki efek yang sama seperti estrogen endogen yang diduga mampu meningkatkan kadar estrogen endogen dalam darah akibat dampak buruk radikal bebas berupa asap rokok. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh ekstrak etanol Rumput kebar (Biophytum petersianum Klotzsch) terhadap lama siklus estrus tikus Rattus norvegicus terpapar asap rokok.Penelitian menggunakan metode eksperimental yaitu pola rancangan acak lengkap (RAL) dengan empat kelompok perlakuan dan tiga kali ulangan.Tikus kelompok negatif diberi makan secaran normal, kelompok kontrol positif diberi paparan asap rokok selama 28 hari, sedangkan tikus kelompok dosis ekstrak etanol rumput Kebar, diberi paparan asap rokok selama 28 hari, dan diberi ekstrak etanol rumput Kebar selama 28 hari. Pengambilan ulas vagina dilakukan pagi hari dengan rentang waktu 24 jam selama 28 hari. Perubahan epitel vagina diperiksa untuk menentukan fase siklus estrus menggunakan mikroskop. Data yang diperoleh dianalisis dengan Analysis of Variance (ANOVA)-SPSS versi 16,0 dilanjutkan dengan uji Duncan dengan selang kepercayaan 95% (α=0.05). Hasil penelitian menunjukkan bahwa pemberian ekstrak etanol rumput Kebar mampu memperpanjang waktu siklus estrus pada dosis 0,135mg/ekor/hari akibat perpanjangan dari fase proestrus dan estrus

Autokorelasi Spasial Untuk Analisis Pola Pengawasan Kawasan Lindung Di Kota Ambon Maluku

Kota Ambon memiliki kawasan lindung yang ditetapkan untuk melindungi kelestarian lingkungan dan sangat sensitif terhadap dampak negatif untuk memenuhi kebutuhan manusia dalam penggunaan lahan. Penelitian ini bertujuan untuk menganalisis pola pengawasan kawasan lindung dalam bentuk data perubahan penutupan lahan pada 50 wilayah di Kota Ambon dengan menggunakan uji autokorelasi indeks Global Moran’s I dan Local Indicator of Spatial Association (LISA), selanjutnya melakukan peramalan pola spasial pada data perubahan penutupan lahan di tahun 2020. Penelitian ini menunjukkan terdapat autokorelasi spasial dari perubahan penutupan lahan untuk kawasan lindung tetapi korelasi melemah dengan nilai indeks Moran’s I berubah dari 0,283362665 menjadi -0,042523054. Peramalan tahun 2020 menunjukkan terdapat autokorelasi spasial pada tingkat perubahan penutupan lahan yang berkorelasi negatif dengan nilai indeks Moran’s I -0,011095491

Studi Kualitas Air Kolam Ikan Air Tawar di Balai Benih Ikan Sentral Masni, Kabupaten Manokwari, Provinsi Papua Barat

Water quality parameters in pond include ammonia, nitrite, nitrate, phosphate, BOD, DO, turbidity, temperature, and pH. It is important to know the concentration of each component to properly minimize the negative impacts of their disturbances for the overall water quality and the biota in it. This study aims to determine the concentration of ammonia, nitrite, nitrate, phosphate, BOD, DO, turbidity, temperature, and pH in freshwater fish ponds at the Central Fish Seed Office (BBIS) of Masni, Manokwari Regency, West Papua Province. The study was conducted in May 2017, representing the rainy season, and August 2017, representing the dry season. Water samples were taken from settling, rearing, hatchery, and brood ponds. Meanwhile, standard method was implemented in the component measurements. The study results show that the concentrations of ammonia, nitrite, nitrate, and phosphate were 0.02-0.18 mg/L, 0.00-2.00 mg/L, 0.40-1.00 mg/L, and 1.01-21.83 mg/L, respectively. Furthermore, the concentrations of BOD and DO were 6.12-8.19 mg/L and 7.30-12.00 mg/L, respectively. Finally, the values ​​of turbidity, temperature, and pH were 0.40-9.99 NTU, 26-30°C and 7.7-8.5, respectively

growth aspects of scad decapterus macrosoma on fish point sanggeng manokwari regency

This study aimed to find the fish distribution in size, heavy - long, and factors condition. This research was doing in March until June 2015. The methods that used to measure are descriptive method and technique observation. The total of sample fish obtained as many as 500 tail. The measure ment of length distribution obtained for individuals male which ranges are 109 -303 mm and 125 – 299 for female. Based on the results of correlation analysis between the length and weight of the fish is all positive and very strong, female fish has a correlation coefficient value 0.6184 with coefficient of determination (R2) 0.3824 and male fish 0,5775 with coefficient of determination (R2) 0,3335. This means there is a close relationship between the weight and body length of the overpass. The result of regression test between the length and weight of the female flying fish is W = 0.0015L2.0321 and the male glider is W = 0.004327 L1.8417, followed by the test of value b (regression coefficient value) obtained b <3 which means the growth of fish pattern shown allometric negative. It means that the length of body rises faster than their weight. In term of factors condition Decapterus sp. Classified in less flattened fish

Distribusi Ukuran dan Tingkat Kematangan Gonad Ikan Julung-Julung Hemiramphus lutkei (Valenciennes, 1847) yang diperdagangkan di Kabupaten Manokwari Papua Barat

This study aims to determine the distribution of length to weight, sex ratio, gonad maturity level of julung fish (Hemiramphus lutkei) traded in Sanggeng and Borobudur Manokwari fish markets, West Papua. Research data collection was carried out for ± 1 month, namely February - March 2021, using a descriptive method. The number of fish samples collected was 542 fish. The results of the analysis of the size distribution of julung-julung fish during sampling for body length ranged from 219 – 355 mm for males and 215 -380 mm for females, with a body weight range of 27-53 grams for males and 30-65 grams. The sex ratio analysis of julung julung fish was obtained for males (321 fish) and females (221 fish) significantly different, which means this ratio deviated from the ideal value of 1:1. Based on the results of the analysis show that the value of X2 -count > X2 -table, then H0 is rejected, which means the sex ratio of male and female fish is not balanced from TKG I-VII for males and TKG II-VII for females and mostly found in TKG III conditions. The size of the male julung fish when the gonads first mature was estimated at a length of about 230-260 mm and the female at a size of 250-280 mm. The average Gonad Somatic Index (GSI) of female julung fish was 0.0876 and the standard error was 0.0061 with a GSI range of 0.0092 – 0.7574. The relation- ship between TKG and GSI shows that the increasing stage of fish gonad maturity will be followed by an increase in the value of the fish gonadal index
