Abstract

This study aims to extract and compare the chemical properties of gelatin from the skin and bone of yellowfin tuna (Thunnus albacares) by using the acid method. The proximate and FTIR analyses of tuna skin and bone gelatin (TSG and TBG) were conducted to determine their chemical properties. The acid condition successfully produced gelatin, which is 3.24% of TSG and 2.61% of TBG yields. The proximate properties revealed that both extracted gelatin BEG and CG fulfil the Indonesian standard quality of gelatin, with a high level of total protein and low lipid content. Amide A, I, II, and III were shown at 3452.58, 1637.56, 1517.98, and 1240.23 cm-1 respectively in TSG FTIR spectra, and at 3493.09, 1660.71, 1533.41, and 1238.30 cm-1, respectively in TBG spectra. Both skin and bone of yellowfin tuna can potentially be used in the production of gelatin for industrial and pharmaceutical purposes with further optimation.

Abstract

Samalona Island, located in Makassar City, South Sulawesi, is one form of the richness of the diversity of islands in Indonesia. The livelihoods of business actors on this island depend on the number of tourists visiting the island. This study aims to determine how the role of culinary tourism business actors on Samalona Island continues to increase so that they can compete with other culinary tours. This study focuses on culinary tourism as an effort to develop and maintain a positive image of Indonesia in the international world through diplomacy, in this case, maritime diplomacy. Local and foreign tourists often visit this island to enjoy the natural beauty and coastal cuisine offered by business actors on this island. Business actors utilize various facilities on this island to continue managing their finances so that their lives remain sustainable and stable. Samalona Island, as a tourist island in Indonesia, needs to receive significant attention from the government and society so that this island remains one of the tourist choices for tourists who want to enjoy the beauty of the Indonesian maritime. The need for more data analyzing the role of culinary tourism business actors on Samalona Island is a novelty in this study.

Abstract

Teachers’ pedagogical competence is an important element in ensuring the quality of learning planning, implementation, and evaluation. Therefore, human resource development needs to be implemented systematically and continuously, including in the context of MI Jamaludin Toya. This study aimed to describe human resource development in improving teachers’ pedagogical competence and identify the supporting and inhibiting factors in its implementation. The study employed a qualitative approach with a descriptive design. Data were obtained through observations, interviews, and documentation, with the madrasah principal and teachers serving as informants. The data were analyzed through data condensation, data presentation, and conclusion drawing, while their validity was examined through source and technique triangulation. The results showed that human resource development was implemented through two main strategies: education and training. The education strategy included upgrading academic qualifications, Pendidikan Profesi Guru (PPG), seminars, and scholarly activities. The training strategy included technical guidance, curriculum training, the preparation of learning materials, assessment, technology utilization, and internal madrasah mentoring, while the Kelompok Kerja Guru (KKG) supported both strategies. Its implementation was supported by the commitment of the madrasah principal and teachers, collaboration among teachers, and support from relevant institutions but was hindered by limited budgets, time and opportunities to participate in training, teacher workloads, and inadequate technological facilities. These constraints were addressed through academic supervision, internal discussions and mentoring, online training, webinars, and KKG activities. These findings confirm that continuous human resource development contributes to strengthening teachers’ pedagogical competence. In practical terms, madrasahs need to develop systematic and needs-based teacher development programs supported by adequate resources.
