Abstract

Lempuk fish is a native Indonesian fish that is endemic in the Ranu Grati tectonic lake, Pasuruan Regency, East Java. This research aims to provide information in efforts to domesticate lempuk fish, especially on reproductive aspects related to the microscopic characteristics of gonads and reproductive type of Lempuk fish (Gobiopterus sp). This research uses the primary sexual characteristics method with gonadal histology. The variables observed included the male to female sex ratio, the histological structure of male and female gonads, and the reproductive type of lempuk fish. All data was analyzed descriptively, qualitatively and quantitatively by comparing with related literature. The samples taken in this research were 39 Lempuk Fish (Gobiopterus sp). The samples were then preserved in 10% formalin. The number of samples for histological analysis was 20 individuals, while for morphometric and meristic analysis there were 8 individuals. The results of the research show that morphologically the lempuk fish has a transparent body shape and there is a central line on the body with black or brown pigment and has a total length of around 2-3 cm. Lempuk fish have a type of reproduction that develops asynchronously (asynchronous) because the development of oocytes in the ovaries of female fish shows a variety of developmental stages, namely the initial growth stage (nuclear and perinuclear chromatin), cortical alveolar, vitellogenesis, and the mature stage. The sex ratio is predominantly female with a ratio of 0.64: 0.36. The histological structure of male and female gonads has histological differences that reflect different reproductive functions, where the ovaries play a role in egg cell production, while the testes are responsible for sperm formation. An imbalance in the sex ratio indicates the importance of carrying out domestication steps in order to prevent extinction or continuous population decline.

Abstract

Introduction: This study aims to determine the differences in fattening results for mud crabs during the west and east seasons.. Method: The research was conducted in Tanjangawan Village, Ujungpangkah District, Gresik Regency, using an exploratory descriptive research method. A total of three ponds with a total of four plots were studied in the west and east seasons, namely in June 2021, December 2021, and May-July 2022. Data collection was carried out in the form of primary data collection using observation, interviews, and active participation. Data were analyzed using Microsoft Excel 2013.The fattening ratio of mud crabs in the west season and the east season was analyzed by t-test (α=5%). Result: The results of this study obtained from data analysis of the Specific Growth Rate of Mud Crabs (Scylla serrata) in Tanjangawan Village, Ujungpangkah District, Gesik Regency, it was found that the growth rate from the west season was higher (1.2%) compared to the growth rate from the east season (0.41%). The survival value in the west season is 95% higher than the east season, with a value of 92.8%. Conclusion: The different conditions between in the west season and east season obtained in this study indicate mud crabs have larger carapace width and weight in the west season due to increased sunlight exposure.

Abstract

Mawlid Nabi is a tradition that has been maintained for decades which experienced developments and innovations by generations. Based on various economic, social, and cultural factors, there are new creations of this traditional ritual resulting from creativity to express love toward the Prophet Muhammad such as Grebeg Tahu as practiced by the people of Sumbermulyo Village, Jogoroto District, Jombang Regency, East Java Province of Indonesia. By inquiring what is the social, cultural, and economic background and how was the new tradition developed, also what is its impact, the authors used the phenomenological method and reinforced it with an anthropological approach. Besides, the Hobsbawm theory of traditional invention was also used as the analytical tool. This study is then indicative that the Sumbermulyo community has a socio-cultural background as Sunni, Nahdiliyin, followers who have had a long tradition of Maulid Nabi. Besides, as most of them are are MSE entrepreneurs in tofu industry, therefore it was what they used to develop the unique ritual of Grebeg Tahu. Finally, this new tradition has proven to have had various impacts on social, cultural, and economic aspects, as well as from a religious perspective
