Abstract

This study aimed to evaluate the effect of fermented red galangal (Alpinia officinarum) extract on the pH value and index of quail eggs during storage. A total of 315 fresh quail eggs were subjected to three treatments: no immersion (P0), immersion in 25% extract (P1), and immersion in 50% extract (P2), using a completely randomized design with five replications. Eggs were immersed for 24 h and stored at room temperature for 0 to 49 days. Observations were conducted on days 0, 7, 14, 21, 28, 35, 42, and 49 for albumen pH, yolk pH, albumen index, and yolk index. The results showed that immersion in fermented red galangal extract significantly reduced the increase in pH of both albumen and yolk compared to the control, particularly at a concentration of 50%. The treatment also slowed the decline in albumen index and yolk index, with P2 consistently maintaining higher values throughout storage. Overall, immersion in 50% fermented red galangal extract was the most effective treatment, extending the internal quality of quail eggs for up to 49 days. This suggests that fermented red galangal extract has potential as a natural preservative for quail eggs, and further studies are recommended to assess microbiological quality and oxidative stability during storage.

Abstract

The sugarcane plantation sector faces significant challenges in achieving cost efficiency and productivity optimization to support national sugar self-sufficiency. This study aims to analyze and compare the economic feasibility of sugarcane farming between the ratoon cane system (keprasan) and the plant cane system (bongkar ratoon) in Jeding Hamlet, Malang Regency, East Java. A quantitative descriptive-comparative method was employed with purposive location determination. The sample consisted of 50 farmers (7 plant cane and 43 ratoon cane) selected through census sampling. Primary data were collected through structured interviews, while secondary data were obtained from relevant government agencies. Feasibility was assessed using production costs, farm income, and the Revenue–Cost Ratio (R/C Ratio). The results show that the ratoon cane system has a lower average total cost (Rp25,642,047/ha) compared to the plant cane system (Rp26,477,429/ha). Although both systems achieved similar average production (48 tonnes/ha), the ratoon system generated higher income per tonne (Rp588,397) than the plant system (Rp534,209). The R/C Ratio values were 2.28 for ratoon and 2.16 for plant cane, indicating both systems are economically viable, with the ratoon system demonstrating superior short-term efficiency. However, the plant cane system remains essential for long-term productivity sustainability, as it can increase productivity by 15–30% with higher rendement. This study recommends intensive nutrient management, particularly timely nitrogen fertilization, in the ratoon system to reduce productivity decline, along with enhanced extension services regarding optimal ratoon cycles and periodic land rejuvenation.

Abstract

Planning coastal tourism landscape areas is an effort to improve the community’s economy. Planning for tourist destinations must take into account land suitability and physical conditions to produce safe, comfortable, and sustainable tourism. This research aims to analyze ten indicators of land suitability, namely Topography, Beach Width, Beach Type, Water Base Material, Beach Depth, Water Brightness, Beach Slope, Dangerous Biota, Availability of Fresh Water, and Vegetation, based on Land Cover type and criteria. This research was carried out in the coastal area of Taraet Hamlet, Betumonga Village, North Sipora District, Mentawai Islands Regency. The analytical methods used in this research are field observations, satellite imagery, and DEM data processed using ArcGIS. Collecting respondents' Hazardous Biota and Fresh Water Availability through FGDs. Based on the results of the analysis, it shows that physically the area has great potential to be developed as a coastal tourism area, with the classification of the Suitable zone as a tourist area covering an area of 554.29 Ha (98%) and the Suitable Zone covering an area of 11.63 Ha (2%).
