PENGARUH PRETREATMENT TERHADAP KUALITAS KARBON AKTIF DARI BATANG ECENG GONDOK (Eichhornia crassipes)
No full textPenelitian ini bertujuan untuk membandingkan kualitas karbon aktif dari batang eceng gondok yang melalui proses pretreatment dan tanpa pretreatment. Eceng gondok dipilih karena merupakan limbah biomassa yang melimpah dan belum dimanfaatkan secara optimal. Metode pretreatment dilakukan untuk menghilangkan pengotor yang menutupi struktur selulosa, sedangkan aktivasi dengan asam asetat bertujuan menghasilkan arang aktif yang memiliki luas permukaan besar. Proses pretreatment dilakukan dengan pemanasan terbuka dalam variasi konsentrasi larutan NaOH (3, 5, 7, 9, dan 11%) selama 60 menit lalu ditentukan kadar selulosanya secara gravimetri untuk mengetahui konsentrasi NaOH yang optimal dan digunakan dalam proses pembuatan arang aktif. Proses aktivasi menggunakan metode refluks dalam larutan CH3COOH 5% dengan variasi waktu (30, 60, 90, 120 dan 150 menit). Karbon aktif yang dihasilkan dikarakterisasi berdasarkan SNI No. 06-3730-1995 yang meliputi uji daya serap iod, kadar air, kadar abu. Selain itu dilakukan uji luas permukaan menggunakan metode Brunauer-Emmett-Teller (BET). Hasil penelitian menunjukkan bahwa larutan NaOH yang efektif untuk meningkatkan kadar selulosa yaitu 7%, sedangkan waktu optimal untuk aktivasi karbon dalam larutan CH3COOH 5% yaitu 120 menit. Kualitas karbon aktif dari batang eceng gondok dengan perlakuan pretreatment maupun tanpa pretreatment telah memenuhi standar SNI No 16-3730-1995 untuk uji kadar air dan kadar abu. Karbon aktif batang eceng gondok dengan perlakuan pretreatment untuk daya serap iod telah memenuhi standar SNI No 16-3730-1995, sedangkan tanpa pretreatment tidak memenuhi parameter uji daya serap iod. Luas permukaan karbon aktif yang dihasilkan dari proses pretreatment lebih besar dibandingkan dengan tanpa pretreatment
PENGEMBANGAN NUGGET OLAHAN TEPUNG TULANG IKAN TUNA (Thunnus sp) DAN ANALISIS KANDUNGAN KALSIUM
No full textA Calcium is an important macromineral that plays a role in bone and tooth formation and helps maintain bone density. Calcium deficiency can increase the risk of osteoporosis. Tuna bone meal is a fairly high source of calcium that can be used as an ingredient in food products such as nuggets. The objective of this study is to help identify and develop alternative calcium sources that can be used in functional food products, such as tuna fish bone flour (Thunnus sp), which has the potential to increase calcium intake in the community. This study used a non-factorial Complete Randomized Design (CRD) consisting of three treatments: P1 (30% tuna fish bone flour), P2 (40% tuna fish bone flour), and P3 (50% tuna fish bone flour). Hedonic testing was conducted on the attributes of color, aroma, taste, texture, and overall quality using a scale of 1–5 by 33 moderately trained panelists. Calcium content analysis in the nuggets was performed using the Atomic Absorption Spectrophotometry (AAS) method. Statistical analysis used the Kruskal-Wallis test and the Mann-Whitney test. The preference test results showed no significant differences in color (p=0.251), aroma (p=0.308), and texture (p=0.643), while there were significant differences in taste (p=0.036) and overall quality (p=0.038). The preference test results showed that panelists preferred formulation P1 in terms of color, aroma, taste, and overall quality, making P1 the best formulation with a calcium content of 3.29%. One serving of tuna fish bone flour nuggets (40g) can meet ±100% of the daily calcium requirement

HISTORY OF CONSTRUCTION IN BATAVIA DURING THE VOC PERIOD AS A FACTOR IN THE DEVELOPMENT OF ARCHITECTURE IN INDONESIA : Sejarah Pembangunan Batavia Sebagai Faktor Perkembangan Arsitektur di Indonesia
No full textArchitecture is an art and science that includes functional, aesthetic, cultural, social, and philosophical values. In the archipelago, architecture has long developed and reflects the influence of local culture, religion, and environment. The arrival of Westerners, especially the Dutch through the VOC, had a major impact on local architecture, creating acculturation between European styles and Nusantara traditions. Batavia Old Town, as the center of Dutch colonial administration, is a clear example of this acculturation. This research uses the architectural historiography method to analyze the history, structure, and influence of Batavia's colonial architecture on the development of the Nusantara's infrastructure. The results show that colonial architectural styles in Batavia, such as the use of local materials and adaptation to the tropical climate, resulted in a distinctive “Indies Vernacular” style. The structure of Batavia city, including its canals and spatial layout, reflects both colonial dominance and heritage that shaped Indonesian architectural identity. In addition, Batavia's Dutch canals have also been implicated in a record of functional failure due to incompatibility with local conditions. This research provides insights into the role of colonial architecture in shaping the infrastructure and urban development of the archipelago

TOURISM APPROACH IN GENTRICOLOGY: PENDEKATAN KEPARIWISATAAN DALAM GENTRIKOLOGI
No full textGentrification is a social phenomenon that involves regional transformation due to changes in social, economic, and cultural structures. This article discusses the relationship between gentrification and tourism through a gentricological approach, focusing on how the development of new areas due to gentrification contributes to the tourism potential in Indonesia. This research highlights the multifaceted role, ranging from government policies, business expansion, to socio-cultural impacts in gentrified areas. Various examples of regions such as Cilegon, Tanjung Bunga, Batam, and Tomohon were analyzed to identify the dynamics between indigenous and immigrant populations and their influence on local tourism activities. The results of the study show that gentrification can support the development of tourism through the emergence of new attractions, infrastructure improvements, and cultural diversification, although on the other hand it has the potential to cause social and economic inequality. These findings underscore the importance of careful and inclusive planning in the gentrification process so that the positive impact on the tourism sector can be maximized without neglecting the social sustainability aspect

IDENTITY FORMATION OF MILLENNIAL GENERATION PARENTS TOWARDS THE TRADITION OF TEDHAK SITEN: Pembentukan Jati Diri Orang Tua Generasi Milenial Terhadap Tradisi Tedhak Siten
No full textThis study examines the process of identity formation among millennial parents concerning the Tedhak Siten tradition in the modern era. Using qualitative methods through in-depth interviews with two pairs of millennial parents (Javanese-Madurese and Javanese-Javanese), this research aims to understand how the millennial generation interprets, experiences, and preserves the Tedhak Siten tradition. The findings indicate that despite the challenges of modernity and globalization, millennial parents still value the traditional values of Tedhak Siten and strive to preserve them through creative adaptations. Their identity formation process is characterized by negotiations between cultural heritage and the demands of modern life, resulting in a more flexible approach to the implementation of this tradition. The personal stories collected reveal how Tedhak Siten becomes an important moment in strengthening family bonds and instilling cultural values in children from an early age, despite various challenges such as time and financial constraints. Efforts to preserve this tradition through social media and informal education demonstrate that millennial parents are capable of balancing the preservation of cultural heritage with adaptation to modern lif
