Effect of Adding Picung Seeds Paste and Storage Time on Total Lactic Acid Bacteria, Salmonella, Water Content and pH in Tilapia Fish: Pengaruh Penambahan Pasta Biji Picung dan Lama Penyimpanan Terhadap Bakteri Asam Laktat, Salmonella, Kadar Air dan pH pada Ikan Nila
Fish is one of the perishable food commodities caused by enzyme activity. The activity of microorganisms present in the body of fish or due to the process of oxidation of body fat through the air. The fermentation process is one way to extend shelf life. The fermentation process in fish can be done with the addition of preservatives such as picung. Picung seeds contain tannins and phenols which are antimicrobial compounds. The addition of picung seeds to fish can also help the growth of lactic acid bacteria if stored in a closed container because picung seeds contain carbohydrates, where sugar is converted into lactic acid. This study used quantitative descriptive methods and focused on the effect of variations in picung concentration (30%, 60% and 90%) as well as storage duration of 3 and 6 days at room temperature to determine the effect on total BAL, Salmonella, water content and pH. The results of this study showed that the addition of picung seeds and storage duration in tilapia can affect the total BAL, Salmonella, water content and pH, with the highest total BAL on the third day with a 60% picung seed paste concentration of 7,4 log CFU/g, negative Salmonella on day 6, then the moisture content value and pH value decreased until day
SURVEI TUTUPAN KARANG DAN KOMPOSISI IKAN KARANG DI PERAIRAN PLTU SEBALANG, LAMPUNG SELATAN
Terumbu karang merupakan ekosistem produktif yang menghadapi ancaman kerusakan akibat penangkapan ikan ilegal dan pembangunan pesisir yang tidak berkelanjutan. Praktik penangkapan ikan ilegal dan pembangunan area pesisir diduga berkontribusi pada penurunan tutupan karang hidup di perairan PLTU Sebalang, Lampung Selatan. Informasi mengenai kondisi ekosistem terumbu karang di area PLTU Sebalang Lampung Selatan saat ini masih belum memadai. Oleh sebab itu perlu dilakukan survei kesehatan terumbu karang di area ini sebagai bagian dari langkah pengelolaan ekosistem terumbu karang secara berkelanjutan. Penelitian ini dilakukan pada bulan Januari 2024 di perairan PLTU Sebalang. Pengambilan data terumbu karang menggunakan metode Underwater Photo Transect (UPT) yang dikombinasikan dengan program identifikai karang CPCe (Coral Point Count with Excel extensions). Pengambilan data ikan karang menggunakan metode Underwater Visual Census (UVC). Hasil penelitian ini menunjukkan kondisi tutupan terumbu karang pada seluruh titik penelitian dikategorikan buruk. Persen tutupan karang terendah berada pada titik 1 kedalaman 8 meter yaitu sebesar 1.53%. Sedangkan kondisi tutupan karang pada titik 2 kedalaman 8 meter memiliki persentase tertinggi yaitu sebesar 23.28%. Ikan karang yang ditemukan sebanyak 10 famili yang terdiri dari Apogonidae, Aulostomidae, Caesonidae, Chaetodontidae, Haemulidae, Holocentridae, Labridae, Nemipteridae, Pomacentridae, dan Pempherididae. Faktor yang mempengaruhi buruknya kondisi tutupan terumbu karang dan sedikitnya jumlah individu ikan karang yang terdapat pada seluruh titik pengamatan dipengaruhi oleh faktor tingginya sedimentasi, kuatnya arus perairan, dan nelayan jaring payang yang menangkap ikan hingga ke dasar perairan.
Coral reefs are productive ecosystems that face significant threats from illegal fishing and unsustainable coastal development. These practices are suspected of contributing to the decline in live coral cover in the waters surrounding the Sebalang Power Plant (PLTU Sebalang), South Lampung. Current information on the coral reef ecosystem in this area remains insufficient. Therefore, a coral health survey is essential as part of sustainable management efforts. This study was conducted in January 2024 in the waters of PLTU Sebalang. Coral reef data were collected using the Underwater Photo Transect (UPT) method, combined with the Coral Point Count with Excel extensions (CPCe) software for coral identification. Data on reef fish were gathered using the Underwater Visual Census (UVC) method. The results indicate that coral reef cover at all study sites was categorized as poor. The lowest coral cover was recorded at Site 1 at a depth of 8 meters, with only 1.53% coverage, while the highest cover was observed at Site 2, also at a depth of 8 meters, with 23.28%. A total of 10 reef fish families were identified, including Apogonidae, Aulostomidae, Caesonidae, Chaetodontidae, Haemulidae, Holocentridae, Labridae, Nemipteridae, Pomacentridae, dan Pempherididae. The poor condition of coral cover and the low number of individual reef fish at all observation sites were influenced by high sedimentation, strong currents, and the use of payang nets by fishermen, which reach the seabed
Proses Gentrifikasi Di Perkotaan Yogyakarta
Gentrification is a process of socio-economic transformation in which areas previously inhabited by low-income or low-middle-income residents are gradually inhabited by higher-income residents. This research combines a case study methodology with a qualitative approach to examine the dynamics of social, economic, and physical changes in several areas affected by gentrification in Yogyakarta, such as Prawirotaman, Kotabaru, and Sosrowijayan. Through in-depth interviews, data were gathered with local residents, entrepreneurs, and government officials, as well as analysis of urban planning documents and statistical data. The results show that gentrification in Yogyakarta is triggered by number of causes, including an increase in the tourism sector, investment in property, and government policies that encourage slum revitalization. The impacts of gentrification include increased property prices, displacement of indigenous residents, changes in cultural character, and social conflicts between newcomers and longtime residents
KARAKTERISTIK DAN TIPOLOGI WILAYAH PERI URBAN KECAMATAN JATI AGUNG, KABUPATEN LAMPUNG SELATAN
Urban development typically brings changes across physical, social, and economic dimensions. These changes affect both the city's core and its peripheral regions, such as the Jati Agung Subdistrict in South Lampung Regency. As a peri-urban zone near Bandar Lampung City, Jati Agung has experienced significant transformations due to the city's influence. This research aims to identify peri-urban characteristics and typologies based on physical, social, and economic parameters in Jati Agung. The analysis involves quantitative descriptive analysis, scoring, and overlay map analysis. Outcomes from this study reveal that the Jati Agung Subdistrict exhibits peri-urban traits in specific villages. Development across physical, social, and economic facets, however, demonstrates non-uniformity throughout the entire area. Villages portraying peri-urban characteristics still lean towards a more dominant rural profile. Typological classification, considering physical, social, and economic aspects, results in two categories within the Jati Agung Subdistrict: secondary peri-urban and rural peri-urban. Six villages manifest secondary peri-urban characteristics, and fifteen villages exhibit rural peri-urban characteristics. The results indicate that as of 2023, the impact of Bandar Lampung City development has not significantly altered the rural characteristics of Jati Agung's villages, as no primary peri-urban areas were identified in the typology
EVALUATION OF HEALTH FACILITIES LOCATION TO SUPPORT ACCESSIBILITY TO ESSENTIAL HEALTH SERVICES IN BANDAR LAMPUNG CITY, LAMPUNG PROVINCE, INDONESIA
Health remains one of the most important aspects of every human life, with access to quality healthcare services being a pivotal component of human well-being. In Indonesia, health facility distribution has been characterized by disparities, primarily concentrated on the populous Java Island. This distribution inequity underscores a significant challenge in achieving Sustainable Development Goals (SDGs) under Goal 3, which aims to ensure healthy lives and promote well-being for all. Bandar Lampung, the most densely populated city in Lampung Province and one of Sumatra's most populated cities, experiences an intensified demand for healthcare facilities due to its substantial population. However, the city grapples with numerous infrastructural challenges, including suboptimal road conditions that hinder accessibility to essential healthcare services. These challenges further underscore the urgency of assessing and addressing the healthcare infrastructure within Bandar Lampung. This research seeks to undertake a comprehensive evaluation of health facility availability in Bandar Lampung City, as well as an in-depth analysis of the accessibility of healthcare services in different areas of the city. To achieve this, the study employs the Network Analysis Tool, which leverages road network data to model travel distances and times. In addition to road network data, geospatial population data sourced is integrated into the analysis to gauge the demand for healthcare facilities within Bandar Lampung. This multifaceted approach is essential in comprehensively addressing the complex interplay between supply and demand in the healthcare sector. The combination of these datasets culminates in the creation of an accessibility model that unveils the disparities in healthcare access across Bandar Lampung. The model highlights areas where accessibility to healthcare facilities remains surprisingly low, despite the city's high population density. Conversely, it also identifies regions with high accessibility, potentially serving as templates for improving healthcare distribution in underserved areas. By revealing these disparities, this research contributes valuable insights to healthcare planning and policy formulation in Bandar Lampung and offers a template for addressing similar challenges in other regions with uneven healthcare distribution
