Judul: The Study of Seloko Adat of Orang Rimba on Biodiversity Preservation in Bukit Duabelas National Park
Abstrak: Seloko adat adalah hukum adat yang dipegang teguh dalam kehidupan sehari-hari Orang Rimba di Taman Nasional Bukit Duabelas (TNBD), yang bertujuan untuk melindungi dan memanfaatkan keanekaragaman hayati. Saat ini, kondisi populasi satwa dan tumbuhan liar di TNBD mulai mengalami penurunan, sehingga keberadaan seloko adat untuk konservasi keanekaragaman hayati mulai mendapat tantangan. Penelitian ini bertujuan untuk mengkaji seloko adat dalam pelestarian keanekaragaman hayati dan memadankan dengan peraturan perundang-undangan nasional tentang konservasi keanekaragaman hayati, serta menentukan kontribusi seloko adat terhadap pelestarian keanekaragaman hayati. Data mengenai seloko adat dikumpulkan melalui wawancara, studi literatur, dan observasi langsung dan dianalisis dengan menggunakan analisis deskriptif kualitatif, sedangkan narasi dari seloko adat tersebut dianalisis dan dibandingkan dengan peraturan perundang-undangan nasional (dengan menggunakan analisis isi). Hasil penelitian menunjukkan bahwa seloko adat Orang Rimba masih di-implementasikan dalam aspek pelestarian, perlindungan, dan pemanfaatan yang berkelanjutan keanekaragaman hayati. Hasil penelitian juga mendapatkan bahwa seloko adat Orang Rimba sejalan dengan peraturan nasional tentang konservasi keanekaragaman hayati. Seloko adat dapat menjadi cara yang efektif untuk melestarikan sumber daya alam. Oleh karena itu, seloko adat dapat digunakan oleh otoritas taman nasional untuk mengembangkan kebijakan pengelolaan keanekaragaman hayati lokal di TNBD., Seloko adat is a customary law adhered in the daily life of the Orang Rimba living in the Bukit Duabelas National Park (BDNP), to protect and utilise biodiversity. The status of wildlife and plants populations in BDNP is declining, so that the existence of seloko adat for biodiversity conservation is being contested. The objectives of this research were to examine the seloko adat in biodiversity conservation in BDNP and to determine its allignment with the Indonesian national laws for biodiversity conservation, and as the contribution of seloko adat to biodiversity. Data on seloko adat were collected through interviews, literature studies, and direct observation and were analyzed using qualitative descriptive analysis, while the contents of the seloko adat were analysed against the national laws using content analysis. The findings indicated that the Orang Rimba seloko adat is still in existence and covered certain aspects of biodiversity conservation. Seloko adat also confirms to legislation on the conservation of biological diversity, hence can be an effective means of conserving natural resources. Seloko adat may be used by the National Park Authority to develop local biodiversity management policies in the BDNP.

Judul: Social Capital and Welfare of Orang Rimba in Bukit Duabelas National Park Jambi Province
Abstrak: The population of the Orang Rimba continues to grow, resulting in an increase in the fulfillment of life needs and changes in forest utilization patterns. These changes are related to the social capital of the Orang Rimba and have an impact on the level of social welfare. This study aimed to identify the elements of social capital and social welfare of Orang Rimba inner and outer, compare the social capital and social welfare of Orang Rimba inner and outer of Bukit Duabelas National Park, and identify the relationship between social capital and social welfare of Orang Rimba. Data collection was conducted by interview and observation in both locations. The results showed that the elements of trust, social networks, social norms, proactive action, and caring did not significantly differ between the Orang Rimba in the two locations. In contrast, there was a significant difference in social welfare, whereas the social welfare of the Orang Rimba inside Bukit Duabelas National Park was higher than that of Orang Rimba outside Bukit Duabelas National Park. Social capital and social welfare tended to show a negative relationship., Populasi Orang Rimba terus bertambah dan mengakibatkan terjadinya peningkatan pemenuhan kebutuhan hidup serta perubahan pola pemanfaatan hutan. Perubahan ini berhubungan dengan modal sosial Orang Rimba dan berdampak pada tingkat kesejahteraan sosial. Penelitian ini bertujuan mengidentifikasi unsur modal sosial dan kesejahteraan sosial Orang Rimba dalam dan luar, membandingkan modal sosial dan kesejahteraan sosial Orang Rimba dalam dan luar Taman Nasional Bukit Duabelas serta mengidentifikasi hubungan antara modal sosial dan kesejahteraan sosial Orang Rimba. Pengumpulan data dilakukan dengan wawancara dan observasi di kedua lokasi. Hasil penelitian menunjukkan unsur kepercayaan, jaringan sosial, norma sosial, tindakan proaktif, dan kepedulian tidak memiliki perbedaan yang nyata antara Orang Rimba di kedua lokasi. Sebaliknya, terdapat perbedaan yang nyata pada kesejahteraan sosial yaitu kesejahteraan sosial Orang Rimba dalam Taman Nasional Bukit Duabelas lebih tinggi dibandingkan Orang Rimba luar Taman Nasional Bukit Duabelas. Modal sosial yang dihubungkan dengan kesejahteraan sosial cenderung menunjukkan hubungan yang negatif.

Judul: Optimation of N-acetylglucosamine Production from Chitin by Aspergillus rugulosus 501 Fermentation .
Abstrak: Chemical hydrolysis of chitin into N-acetyl-glucosamine (GlcNAc) using strong acid such as HCl will damage environment and hard. Enzymatic hydrolysis using chitinase is an alternative method to overcome such problems. Fermentation was done by A. rugulosus 501 (1% v/v) using GlcNAc production medium with variation initial pH (4, 5, 6, and 7) and nitrogen source (bacto peptone, yeast extract, ammonium sulphate, and urea). Samples were to be at day 0; 5; 6; 7; 8; 9 10 and measured using Reissig method. Chemical of GlcNAc tied by calium tetraborat then added reagent p-dimetilaminobenzaldehida (DMAB) and absorbtion measured at 584 nm wave. The obtained GlcNAc were to be concentrated using evaporator and freeze dryer. The results showed that GlcNAc concentration obtained was very low. The optimal production (2,228 μg/mL) were observed at the initial pH 4 and urea as nitrogen source at day 10.
