Abstract

Skipjack tuna (Katsuwonus pelamis) is one of tuna fish species in Indonesia,which is perishable and must be kept its freshness by chilling. Aim of this research were to optimize influenced quality factors and to find the best method for reduce deterioration process. The research was conducted by using Taguchi Method, which was used quality robustness concept and multi-performance characteristics to achieve optimal combination of factors. Controlled factors during chilled storage were; weight ratio of ice and fish (A), box size (B), time replacing ice (C), ice form (D), concentration of added salt (E), fish form (F) and number of fishes per kg (G). Quality responses for assessing the freshness were; peroxide value (POV), water content (WC), pH value, texture and Total Plate Count (TPC). The result showed, increase of peroxide value was affected by A of 26.52% and C of 26.52%. Increase of water content was influenced by F of 37.25%. Fluctuation of pH was affected by G of 59.58%. Decrease of texture was influenced by A of 40.47%. Increase of TPC was influenced by A of 31.20%. Priority Scale of factors during storage were A, E, D, G, F, B, and C. Result of analysis muli-performance characteristics gave a conclusion that factors A1, B1, C1, D2, E2, F2 and G2 are the best chilling storage methods.

Abstract

This article aims to investigate the accommodation of stakeholders’ voices and it’s challenges in the practices of curriculum development. Using a qualitative approach, the primary data was gathered through in-depth interviews with the head and secretary, and the administrative staff of four Study Programs in The School of Post Graduate Program of one of the leading universities in Yogyakarta, Indonesia. Whereas, secondary data was taken from the documents of curriculum reviews and accreditation documents. The research found that amidst the complexity of involving stake holder’s views within curriculum design, all the four programs have gathered the stake holders’ voices via tracer study, informal discussion during academic meetings and evaluation from the students.  The accommodation of stake holders’ voices can be traced in the form of the addition of elective courses, merging of some courses, addition or omission of certain courses in the current curriculum design. However, the practice of curriculum development was challenged by various aspects such as the commitment of Study Programs to maintain their ‘scientific core’ vis a vis addressing market demand given their commitment to improve theories and knowledge, and the limitation of human resource availabilityArtikel ini Betjeman untuk meneliti akomodasi terhadap masukan stakeholder serta tantangannya dalam praktik pengembangan kurikulum. Menggunakan pendekatan kualitatif, data primer dikumpulkan melalui wawancara dengan ketua dan sekretaris, dan staf administrasi pada empat program studi di Program Pascasarjana di salah satu universitas terkemuka di Yogyakarta, Indonesia. Sementara itu, data sekunder diambil dari dokumen review kurikulum dan akreditasi. Penelitian ini menemukan bahwa di tengah kompleksitas pelibatan stake holder dalam desain kurikulum, keempat Program Studi mengumpulkan masukan stakeholder melalui tracer study, diskusi informal dalam pertemuan-pertemuan akademik dan evaluasi dari mahasiswa. Akomodasi yang dilakukan Program Study dapat dilacak dalam bentuk penambahan mata kuliah tambahan, penggabungan beberapa mata kuliah, penambahan atau pengurangan mata kuliah tertentu dalam desain kurikulum yang baru.  Akan tetapi, pelaksanaan pengembangan kurikulum tersebut menghadapi tantangan berupa komitmen Program Studi untuk mempertahankan ‘inti keilmuan’ dihadapkan dengan bagaimana mengakomodir tuntutan pasar mengingat bahwa Program Studi memiliki komitmen untuk pengembangan teori dan pengetahuan, dan keterbatasan sumber daya manusia di Program Studi.
