"Ayam nisi merupakan salah satu spesies ayam lokal asli Indonesia yang berasar dari Gorontalo. Di daerah Gorontalo sendiri, ayam nisi dikenal dengan istilah “maluo nisi/ maluo diti” yang berarti ayam kecil. Keterbatasan informasi mengenai ayam ini membuat penelitian ini menjadi penting untuk dilakukan sehingga dapat menjadi salah satu sumber informasi dalam mendukung penelitian mengenai keanekaragaman ayam lokal di Indonesia. Hasil analisis morfometrik menunjukkan bahwa bahwa hubungan sangat erat atau dekat terjadi antara pada lebar paha (0,942) dengan lingkar lutut (0,898) karna terletak pada satu kuadran yang sama, yaitu kuadran 1. Kemudian hubungan dekat juga terjadi pada variabel Panjang tubuh (0,864) dengan lebar dada (0,865). Lalu kedekatan antara variabel panjang paha (0,850) dengan panjang sayap (0,833). Kemudian lingkar paha (0,817) dengan lingkar dada (0,812), lalu hubungan dengan panjang rusuk (0,741) dengan panjang jari ke- 3 (0,668) dan terakhir hubungan kedekatan antara panjang mulut (0,636) dengan panjang leher (0,702). Hasil analisis bioakustik menunjukkan nilai durasi kokok pada sampel yang terdiri dari 30 ayam jantan menunjukkan rata- rata 1,9837 detik, Frekuensi rata-rata sebesar 733,89 Hz dan jumlah suku kata berjumlah 7 suku kata. Hasil analisis jarak genetik menunjukkan bahwa kekerabatan paling dekat dimiliki oleh ayam ketawa dengan ayam kampung (0,0840). Ayam nisi dan ayam ketawa memiliki hubungan kekerabatan yang lebih dekat (2,7258) dibandingan hubungan kekerabatan antara ayam nisi dan ayam kampung. Kedekatan ayam nisi dan ayam ketawa ditunjukkan dengan jarak genetik sebesar (3.5491). Berdasarkant kajian dari tiga masalah tersebut, maka penelitian ini diharapkan dapat memberi kontribusi terhadap upaya konservasi dan penelitian untuk mengungkap informasi ayam nisi sehingga studi lanjutan bermunculan untuk mengungkap keberadaan ayam nisi. Studi ini diharapkan dapat menjadi pembuka jalan agar ayam nisi dapat dikenali secara luas dan sebagai upaya untuk melestarikan ayam nisi yang informasi dan keberadaannya sangat sulit untuk ditemukan.

Nisi chicken is one of the native Indonesian native chicken species from Gorontalo. In the Gorontalo area itself, nisi chicken is known as "maluo nisi/maluo diti" which means small chicken. Limited information about this chicken makes this research important to do so that it can be a source of information to support research on the diversity of local chickens in Indonesia. The results of the morphometric analysis show that there is a very close or close relationship between thigh width (0.942) and knee circumference (0.898) because they are located in the same quadrant, namely quadrant 1. Then a close relationship also occurs in the body length variable (0.864) with chest width (0.865). Then the closeness between the variable thigh length (0.850) and wing length (0.833). Then the circumference of the thigh (0.817) and the circumference of the chest (0.812), then the relationship between the length of the ribs (0.741) and the length of the 3rd finger (0.668) and finally the close relationship between the length of the mouth (0.636) and the length of the neck (0.702). The results of the bioacoustic analysis showed that the duration of the crow in the sample consisting of 30 roosters showed an average of 1.9837 seconds, an average frequency of 733.89 Hz and a total of 7 syllables. The results of genetic distance analysis show that the closest kinship is between the laughing chicken and the native chicken (0.0840). Nisi chicken and laughing chicken have a closer kinship (2.7258) than the kinship between nisi chicken and native chicken. The closeness between nisi and laughing chickens is indicated by a genetic distance of (3.5491). Based on the study of these three problems, it is hoped that this research can contribute to conservation and research efforts to uncover information on nisi chickens so that further studies emerge to reveal the existence of nisi chickens. This study is expected to pave the way so that nisi chickens can be widely recognized and as an effort to preserve nisi chickens whose information and whereabouts are very difficult to find."

"There are seven species of marine turtles known throughout international waters. These are Loggerhead turtle/Caretla carelta (Linnaeus, 1758), Green turtle/Chelania mydas (Linnaeus, 1766), Kemp's ridley turtlell.epidochelys kempii (Garman, 1880), Olive ridley turtle/1,epidochelys olivacea (Eschscholtz, 1829), Flatback turtle/Natator depressus (Garman, 1880), and Leatherback turtle/Dermochelys coriacea (Vandelli, 1766).In Indonesian waters, there are six species of marine turtles. Kemp's ridley turtle is the only species from the above, which is not found.The status of the Olive ridley turtle in the Red DataBook-IUCN (International Union for Conservation of Nature and Natural Resources) is 'Endangered'. CITES (Convention on International Trade of Endangered Species of Wild Flora and Fauna) categorizes this species in `Appendix I' meaning that the trading of this animal should be limited. In Indonesia, the Olive ridley--along with the Leatherback, Hawksbill, Flatback and Loggerhead turtle--is listed as a protected species, while the Green turtle is the only turtle species not protected by regulation.Compared with other species of turtle, there is still lack of documentation concerning the Olive ridley turtle in Indonesia. So far, there is still relatively little publication about this species. The main reason is probably because of the limited knowledge of the Olive ridley nesting beach's location. For this reason, research was conducted at Pantai Marengan, in Alas Purwo National Park (Alas Purwo NP), Banyuwangi, East Java. This is one of the few known nesting sites of the Olive ridley turtle in Indonesia.The aim of the research was to investigate the nesting of the Olive ridley turtle. A study of morphometrics and captive program in Alas Punvo NP was also made as part of the research. It is hoped that, the results will be useful for the conservation of the turtle and its habitat.The research was performed during the turtle's nesting season, between March and October 1995. During this period, one hundred and sixty-two (162) nests were found. The peak of activity occurred in July, when fifty-one (51) nests were located. The average clutch size was one hundred and four (104) eggs per nest. On average, the nests were located 5.8 m (SD = 6.7) from vegetation and 18.5 m (SD = 11.5) from the highest high tide mark. The morphometric study of thirty (30) nesting turtles showed that the average curved carapace measurements were 67.5 cm in length (SD = 3.2) and 66.7 cm in width (SD 3.9). The results of carapace measurements showed that the carapace length positively correlated with carapace width, i.e., as the carapace length increase, so the carapace width will also increase. No correlation was found between carapace length and the number of eggs in each clutch. There was also no correlation found between the number of eggs laid and the time used for nesting activity.The captive program of Olive ridley turtle in Alas Purwo NP was set-up in 1989. The survival percentage of hatchlings from semi-natural hatching recorded during the 1995 season was 83.7 %. The highest hatching death rate (45.3 %) occurred in August, when temperature in the rearing container fell to 20"C.According to the secondary data, during the 1984/1985 nesting season, only three (3) nesting sites of the Olive ridley turtle were found in Alas Purwo NP. In the period between April and June 1996, however, one hundred and sixty-nine nesting sites were located. Is population of the Olive ridley turtle increasing within the Alas Purwo NP? The question can only be answered more accurately by tagging of individual animals and monitoring the species over a longer term."

"Macaca fascicularis merupakan primata yang sering digunakan sebagai hewan uji dalam penelitian, sehingga kondisi fisiologisnya harus diperhatikan karena berpengaruh terhadap hasil penelitian, terutama penelitian tentang pertumbuhan. Standarisasi berat badan dan morfometri membantu penelitian tentang pertumbuhan, namun standarisasi tersebut memerlukan sampel yang banyak agar hasil tidak bias. Penangkaran milik PT Indo Biomedical, Jonggol memiliki banyak M. fascicularis dan belum memiliki standar data morfometri dan berat badan, sehingga dapat dilakukan penelitian penentuan standar data berat badan dan morfometri di penangkaran tersebut.

Macaca fascicularis is a kind of primate that often used as animal model in research, therefore, physiological condition must be considered because the influence of the result of research. Standardization of weight and morphometry assist research on growth, but these standards require that many samples that the results are not biased. Captive owned by PT Indo Biomedical, Jonggol has a lot of M. fascicularis and did not yet had data standard morphometry and weight, therefore it can be done research determination standardization of weight and morphometry in there.

The purpose of this study was to get a M. fascicularis basic standard characteristics of morphometrics and body weight. The number of animals observed were 698 consisting of 175 babies, 248 infants, 209 juveniles, and 66 sub-adults. The parameters were included body weight, body length, tail length, upper arm length, forearm length, thigh length, and calf length.

The Principal Component Analysis (PCA) showed that the individu of M. fascicularis of the babies and the infants age-group had the best forearm length parameter measurement standard, while the juveniles and the sub-adults age-group of M. fascicularis had the best upper arm length as their best parameter measurement standard. The result of processing data used T-test of mean of morphometrics and body weight indicated there was real significance of morphological differences between male and female individuals of M. fascicularis sub-adult age groups."

"Kawasan Universitas Indonesia termasuk ke dalam kawasan urban yang memiliki keanekaragaman berbagai famili tumbuhan, salah satunya adalah tumbuhan invasif. Jenis-jenis tumbuhan invasif di kawasan Universitas Indonesia terekam dan menjadi koleksi Herbarium Depokensis (UIDEP). UIDEP sebagai herbarium tingkat universitas yang berada di bawah Departemen Biologi FMIPA UI menyimpan koleksi awetan botani yang dapat berperan sebagai rujukan dan dimanfaatkan dalam penelitian di berbagai bidang. Akan tetapi, spesimen tumbuhan invasif koleksi UIDEP belum mempunyai kondisi fisik yang representatif dan informasi taksonomi yang valid sehingga memerlukan upaya manajemen herbarium. Tujuan penelitian ini adalah untuk memperoleh koleksi spesimen tumbuhan invasif yang valid dan representatif di UIDEP melalui manajemen herbarium supaya dapat dijadikan rujukan ilmiah. Proses manajemen herbarium dilakukan terhadap 56 spesimen tumbuhan invasif dan terdiri atas validasi taksonomi, perawatan dan perbaikan spesimen, serta digitalisasi dan pengunggahan data spesimen ke pangkalan data herbarium. Sebanyak 11 jenis dari 6 famili tumbuhan berhasil didapatkan lewat morfometrik karakter morfologi dan identifikasi spesies. Famili Poaceae merupakan famili dengan anggota jenis invasif terbanyak (4 jenis), sedangkan spesies Asystasia gangetica merupakan spesies tumbuhan invasif dengan jumlah lembar spesimen terbanyak (15 lembar). Hasil validasi taksonomi juga menunjukkan 2 lembar spesimen Panicum sp. dan 2 lembar spesimen Pennisetum polystachion mengalami perubahan nomenklatur sesuai tata nama botani yang berlaku saat ini. Terdapat 29 lembar spesimen yang mengalami permasalahandan memerlukan tindakan perbaikan sesuai dengan permasalahan yang dialami pada lembar spesimen masing-masing. Proses digitalisasi spesimen selanjutnya dilakukan dengan pengubahan informasi label tempel ke dalam bentuk tabel Excel, pendokumentasian spesimen, dan pengunggahan data ke pangkalan data UIDEP melalui situs web (ruangkoleksibiotaui.id). Spesimen herbarium yang telah valid dan representatif melalui manajemen herbarium diharapkan dapat dimanfaatkan oleh masyarakat luas.

The University of Indonesia area is an urban area with a diversity of plant families, one of which is an invasive plant. Invasive plant species in the University of Indonesia area were recorded and became the Herbarium Depokensis (UIDEP) collection. UIDEP, as a university-level herbarium under the Department of Biology FMIPA UI, keeps a collection of preserved botanicals that can serve as a reference and be used in research in various fields. However, specimens of invasive plants from the UIDEP collection require herbarium management efforts to have representative physical conditions and valid taxonomic information. This study aimed to obtain a valid and representative collection of invasive plant specimens at UIDEP through herbarium management to be used as scientific references. The herbarium management process was carried out on 56 specimens of invasive plant and consisted of taxonomic validation, specimen maintenance and repair, and digitization and specimen data upload to the herbarium database. A total of 11 species from 6 plant families were obtained through morphometric characters and species identification. The Poaceae family is the family with the most invasive species (4 species), while Asystasia gangetica is the invasive plant species with the highest number of specimens (15). The taxonomic validation results also showed 2 specimens of Panicum sp. and 2 specimens of Pennisetum polystachion underwent nomenclature changes according to the current botanical nomenclature. There are 29 specimen sheets that experience problems and require corrective action following the problems experienced on each specimen sheet. The process of digitizing the specimens was then carried out by converting the patch label information into an Excel table, documenting the specimens, and uploading the data to the UIDEP database via the website (ruangkoleksibiotaui.id). It is hoped that the wider community can utilize herbarium specimens that have been valid and representative through herbarium management."
