Judul: Mempelajari Pengaruh Jumlah Lapisan dan Dimensi Kemasan terhadap sifat Dinamis Buah Tomat (Lycopersicum esculentum mill)
Abstrak: Buah-buahan dan sajwan termasuk komoditi yang mudah sekali rusak. Kerusakan mekanis pada buah dan sayuran dapat terjadi pada saat penganglxtan. Kerusakan nlg~anis selama penganglatan disebabkan oleh getaran karena tunlpukan dalam kemasan. Penelitian mengenai sifat dinamis buah dalam kernasan berguna uniuk mnerangi kerusakan ntekanis pada buah. Hasil pengamatan yang dilakxkan pada peneiitian ini dapat digunakart untuk ~ttempsiajari pengaruh junllah lapisan tuntpukan buah tomat da?am i&adap slfat dinamisnya serta mentpefajan pengaruh dlmensr kemasan terhadap srfar dinantis buah tomat.

Judul: Mempelajari proses kerusakan fisik buah tomat (Lycoporsicum esculentum Mill.) dalam bangunan sederhana
Abstrak: Dipelajari pengaruh suhu dan lama penyimpanan terha- dap perubahan kualitas tomat dan kebutuhan beban pendingi- nannya dalam bangunan yang menggunakan tripleks. Tomat pada penelitian ini disimpan pada 3 (tiga) kon- disi penyimpanan masing-masing pada suhu 0 5° C, 5- - 10°C dan 25 30° C (suhu lapang), dengan lamanya penyimpanan - 12 (dua belas) hari. Pengamatan dilakukan setiap hari terhadap perubahan Total asam, Total gula, Vitamin C, Kadar air, PH, Kekera- san, dan Pola respirasinya. Hasil penelitian yang dilakukan menunjukkan, bahwa suhu dan lamanya penyimpanan sangat berpengaruh terhadap perubahan kualitas tomat yang disimpan. Ditinjau dari keseluruhan mutu tomat yang dianalisa, disimpulkan bah- wa penyimpanan pada kondisi suhu 5 10° C adalah yang - terbaik, dengan lama penyimpanan maksimal 8 hari, sehing- ga kesegarannya masih baik. Dengan menggunakan tripleks sebagai bangunan penyim- panannya, maka selama penyimpanan 8 (delapan) hari pada suhu 5 10°C dibutuhkan 1.967 ton pendinginan....

Judul: Studi sistematika  Oreophryne Boettger, 1895Sulawesi (Anura: Microhylidae)
Abstrak: The cross frogs, genus Oreophryne Boettger, 1895 are most diverse in the mainland of New Guinea and adjacent islands, to the Wallacea region in the Moluccas, Sulawesi, and the Lesser Sunda Islands, even marginally to the Oriental region in Bali and to the southern Philippine Islands. In Sulawesi, this taxon consists of three species but has rarely been reported since their original descriptions and remained unstudied in both taxonomical work and molecular study. This research aims to evaluate the taxonomic status of the cross frogs in Sulawesi based on morphology and estimate the phylogenetic using the 16S rRNA gene. The phylogenetic tree was reconstructed under Maximum Likelihood (ML) and Bayesian Inference (BI) analyses. We used the specimens of Sulawesian Oreophryne which were stored at the Museum Zoologicum Bogoriense (MZB). A total of about 19 morphological characters were measured by a digital caliper and ocular micrometer to the nearest 0.01 mm. The phylogenetic tree shows that the three nominal species of Oreophryne from Sulawesi are clearly clustered. Correspondingly, the phylogenetic analysis supports the recognition of a new taxon, Oreophryne sp. However, the phylogenetic relationships between Oreophryne within Wallacea remain unresolved. Consequently, further systematic analysis along with additional sequences from the type locality is necessary to clarify the interspecific relationship among this region. We examined the morphology of 50 voucher specimens of Sulawesian Oreophryne. The validity of O. celebensis, O. variabilis, and O. zimmeri was confirmed in this study, but still the latter remains to be established. The three nominal species examined here were not collected from the type locality, so additional specimens, either in the type locality, new locations, or in other areas on this island are needed to evaluate the taxonomic status of these species deeply. Moreover, the unnamed species from the highland of the Mekongga mountains differ morphologically and genetically from all previously described Sulawesian Oreophryne. This distinct species will increase the number of cross frogs in Sulawesi to four species, all of which are endemic.
