Abstract

ABSTRACTHybridization program was started in PKBT IPB Bogor in 2003, entangles of 12 parental cultivars, consisting of five type Smooth Cayenne cultivars and seven type Queen cultivars. The cross yielded 195 genotypes with various different character combinations. The result of cluster analysis based on morphological characters showed that there were 33 groups of hybrid at the degree of genetic similarity of 50%. The result of principal component analysis indicated that, between yield component characters and result most importantly, were fruit weight, fruit diameter and fruit length which were main supporting character of variance in hybrid result of the crosses. Descriptive results of fruit yield and quality characters showed three to five classes with the highest number of individuals around the mean value for each character. Fruit weight, crown weight, fruit length, fruit diameter, flesh thickness, core diameter, total soluble solid (TSS), total acid, vitamin C, pH, plant height, and peduncle length, were characters controlled by nuclear genes.Key words : hybridization, variability, Smooth Cayenne, Queen, genotype

Abstract

Konservasi Aroen Meubanja telah melakukan perlindungan terhadap habitat penyu dengan cara menyelamatkan telur penyu dari berbagai ancaman predator dengan memindahkan ke zona konservasi yang dapat dipantau dan diawasi secara langsung. Setelah telur-telur penyu tersebut berhasil diselamatkan, kemudian telur dipindahkan untuk ditetaskan, setelah menetas tukik penyu dipelihara di bak penampungan sementara selanjutnya tukik dilepas kehabitat aslinya. Tujuan pengabdian kepada masyarakat ini adalah memberikan pengetahuan kepada mahasiswa untuk mengenal kehidupan, tingkah laku, kebiasaan dan karakteristik habitat penyu. Kegiatan ini sangat bermanfaat untuk menambah wawasan dan kesadaran mahasiswa dalam upaya melestarikan penyu. Pelaksanaan kegiatan dilaksanakan di Desa Aroen Meubanja, Kecamatan Panga, Kecamatan Aceh Jaya. Kegiatan ini diikuti oleh mahasiswa Fakultas Perikanan dan Ilmu Kelautan, Universitas Teuku Umar. Metode pelaksanaan kegiatan pengabdian masyarakat yang digunakan adalah metode sosialisasi edukasi pembesaran tukik melalui penyampaian materi dan diskusi dalam upaya pelestarian penyu yang baik dan benar. Materi yang diberikan berupa teknik pembesaran tukik mulai dari penetasan telur dan pemeliharaan tukik hingga pelepasan tukik ke laut. Edukasi metode pembesaran tukik melalui konservasi habitat penyu, diharapkan dapat meningkatkan pengetahuan mahasiswa, mendapatkan informasi dan pemahaman mengenai aspek pola hidup, tingkah laku, karakteristik habitat dan kebiasaan makan penyu, agar dapat berjalan optimal sehingga meminimalkan kematian penyu serta mengetahui upaya konservasi penyu yang baik dan benar.

Abstract

The implementation of the Merdeka Curriculum is a strategic government policy aimed at improving the quality of education, particularly vocational education that is oriented toward graduates’ work readiness. This study aims to analyze the implementation of the Merdeka Curriculum at Vocational High School 4 Tebing Tinggi in improving the quality of education, as well as to identify the inhibiting factors in its implementation. This research employs a qualitative approach with a descriptive method. Data collection techniques include observation, in-depth interviews, and documentation. The research informants consist of the principal, vice principals, teachers, and students of Vocational High School 4 Tebing Tingg. The results show that administratively, the Merdeka Curriculum has been implemented at Vocational High School 4 Tebing Tinggi; however, its implementation has not yet been optimal. This is indicated by the continued dominance of conventional learning patterns, teachers’ limited understanding of project-based learning, and students’ lack of understanding of the objectives and mechanisms of the Merdeka Curriculum. The inhibiting factors in the implementation of the Merdeka Curriculum include ineffective policy communication, limitations in human resources and facilities, as well as uneven readiness among policy implementers.
