Judul: Developing of inventory systems in Mango var. Gedong gincu supply chain
Abstrak: Kendala utama dalam sistem persediaan untuk komoditas hasil pertanian adalah umur simpan. Umumnya, model-model persediaan yang dibangun dalam sistem persediaan mengasumsikan bahwa produk memiliki umur simpan tidak terbatas sehingga dapat disimpan selama-lamanya untuk memenuhi permintaan di masa datang. Kenyataannya, produk mempunyai umur simpan terbatas karena mengalami perubahan dalam penyimpanan akibat penurunan mutu, kerusakan dan keusangan (obsolescence). Untuk produk hasil pertanian, selain aspek musiman dan kamba, aspek mudah rusak (perishable) menjadi faktor penting dalam sistem persediaan komoditas hasil pertanian. Khusus untuk produk segar, misalnya buah segar, aspek penurunan mutu dan susut bobot yag menunjukkan tingkat kesegaran (freshness) merupakan parameter mutu kritis yang dijadikan pertimbangan dalam mempertahankan mutunya. Mangga gedong gincu merupakan salah satu produk yang termasuk dalam klasifikasi produk yang tidak tahan lama dalam penyimpanan (perishable product), dimana akan terjadi penurunan mutu dalam waktu tertentu. Setelah dipanen, buah mangga tetap melakukan kegiatan metaboliknya seperti respirasi dan transpirasi yang dapat menyebabkan perubahan fisikokimia buah pascapanen, seperti proses pematangan, pembentukan aroma dan kemanisan, pelunakan daging buah dan penurunan nilai mutu. Kondisi tersebut memerlukan kebijakan yang tepat untuk mendukung sistem persediaannya.

Judul: Kajian Perubahan Mutu Buah Mangga Gedong Gincu  Selama Penyimpanan Dan Pematangan Buatan
Abstrak: The objective of this research is to evaluate quality changes of mango var. Gedong Gincu during storage and artificial ripening process based on some parameter that is respiration rates, weight loss, total soluble solid, firmness, colour and organoleptic. The result show that the temperature of storage and artificial ripening have significant effect to respiration rates, weight loss, total soluble solid, firmness, colour and organoleptic. High temperature of storage and artificial ripening hence cimateric rise progressively. From the result of research, organoleptic score to temperature of storage and artificial ripening increasing until fourth day after artificial ripening. This matter is possibility indication not yet been perfect maturation process, it means mango can kept longer time.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
