"ABSTRAKPenelitian mengenai pemanfaatan Abstrak Hasil Penelitian Pertanian Indonesia (AHPPI) terbit PUSTAKA oleh para peneliti di 9 instansi Balitbang pertanian Departemen pertanian di Bogor dan Jakarta pada bulan April sampai Juni 1995, tujuannya untuk mengetahui seberapa jauh para peneliti Balitbang pertanian mengetahui dan memenfaatkan AHPPI, bagaimana pendapat mereka tentang AHPPI ditinjau dari segi kala terbit, kemutakhiran informasi, jumlah abstrak tiap kali terbit, format dan susunan, kesulitan penggunaan, relevansi dengan kegiatan penelitian, banyaknya waktu yang dihemat serta frekuensi pemakaian, dan tujuan yang terakhir untuk mengetahui apa harapan mereka terhadap AHPPI.Pengumpulan data lapangan dilakukan melalui kuesioner yang dibagikan kepada responden oleh staf berwenang di instansi yang bersangkutan. Cara penyusunan kuesioner, pembentukan dan pemilihan kerangka sampel dijelaskan. Hasilnya menunjukkan bahwa hanya 38,04 % yang mengetahui dan menggunakan AHPPI, dan selebihnya sekitar 61,96 % tidak pernah menggunakan AHPPI. Dari 38,04 % yang pernah menggunakan AHPPI menyatakan bahwa AHPPI sudah cukup baik. Harapan semua responden terhadap AHPPI adalah agar AHPPI lebih diromosikan pada para peneliti.

"Diversitas Molekuler Berbasis ISSR pada Durio tanjungpurensis Asal Kalimantan Barat, Indonesia. Durian Tengkurak (Durio tanjungpurensis Navia) adalah salah satu spesies langka yang eksotis dari suku Malvaceae. Durian tersebut bernilai penting untuk konservasi plasma nutfah dan berpotensi sebagai sumber daya genetik untuk pengembangan durian di masa depan. Tujuan penelitian adalah mengetahui keragaman molekuler D. tanjungpurensis asal Kalimantan Barat berdasarkan penanda Inter Simple Sequence Repeat (ISSR). Sepuluh primer ISSR digunakan untuk mengetahui keragaman genetik 60 individu Durian Tengkurak dari enam populasi endemik alami D. tanjungpurensis. Parameter keragaman genetik didasarkan pada data biner pita DNA produk PCR, yaitu ada atau tidak- ada pita. Hasil penelitian menunjukkan bahwa rata-rata jumlah alel, rata-rata jumlah efektif alel, diversitas genetik, indeks informasi Shannon, jumlah polimorfik lokus, dan persentase polimorfik lokus berturut-turut adalah 1,53, 1,29, 0,17, 0,26, 77,83 dan 52,59. Analisis ragam molekuler (AMOVA) menunjukkan keragaman genetik yang lebih tinggi di dalam populasi (65%) dibandingkan antar populasi (35%). Analisis gugus menggunakan metode UPGMA berdasarkan matriks keserupaan Dice dan analisis koordinat utama digunakan untuk mengelompokkan semua individu populasi ke dalam tiga kelompok, yaitu grup 1 (Hutan Rejunak dan Tembaga), grup 2 (Bukit Merindang), dan grup 3 (Hutan Rawak, Bukit Sagu 1 dan Bukit Sagu 2). Analisis lebih lanjut terhadap struktur populasi menggunakan program STRUCTURE menyatukan grup 2 dan 3 ke dalam satu grup utama. Penelitian ini berhasil mengungkap keragaman genetik Durian Tengkurak menggunakan penanda ISSR.

The Durian Tengkurak (Durio tanjungpurensis Navia) is one of the endangered exotic species in the Malvaceae family. The species is important for conservation of the germplasm and is considered a potential genetic resource for the development of durian in the future. The objective of this research project was to assess the molecular diversity of D. tanjungpurensis in West Kalimantan, based on Inter Simple Sequence Repeat (ISSR) markers. We applied ten ISSR primers to reveal the genetic diversity of 60 individuals from six natural endemic D. tanjungpurensis populations. The genetic diversity parameters were estimated based on binary data about PCR products (present or absent bands). The results showed that the mean number of observed alleles, the mean number of effective alleles, the genetic diversity, the Shannon?s Information Index score, the number of polymorphic loci, and the percentage of polymorphic loci were 1.53, 1.29, 0.17, 0.26, 77.83, and 52.59, respectively. An analysis of molecular variance (AMOVA) showed that the genetic diversity within a population (65%) was higher than that found between the populations (35%). UPGMA clustering and principal coordinate analysis, based on the DICE similarity matrix, were used to classify the populations into three groups: 1) Hutan Rejunak and Tembaga, 2) Bukit Merindang, and 3) Hutan Rawak, Bukit Sagu 1, and Bukit Sagu 2. Further analysis of the population structure using STRUCTURE software was used to classify all the individuals into two major categories, thus uniting Groups 2 and 3 as one major category. In conclusion, a high level of genetic diversity in the Durian Tengkurak was revealed utilizing the ISSR markers employed in the study."

"ABSTRACTProviding accurate information on suitable multispectral satellite sensors for mapping coral reefs in Indonesia is a challenge for coastal remote-sensing experts. As coral reefs vary in spatial extent, shape, length, perimeter and/or distance to shore, the mapping of coral reefs will need different satellite sensors depending on the objectives and the kind of information required. This work compares the suitability of two kinds of multispectral satellite sensors for mapping coral reefs in Indonesia, high and moderate spatial resolution. This was done through a case study of Wakatobi Marine National Park since that represents many types of coral reef in Indonesia (fringing, barrier, atoll, and patch). Indonesian coral reef shapefile data 2010 was downloaded from UNEP (United Nations Environment Programme) website, and Landsat 7 ETM + images, path/row 112/064 was used to determine the terrestrial area of Wakatobi Islands. Both high and moderate spatial resolution sensors are suitable for mapping the benthic communities and geomorphic zones on coral reefs. The former are more accurate but they are also much less cost-effective, especially over large areas."

"Three specimens of Plectranthias retrofasciatus Fourmanoir and Randall, 1979 and one specimen of P. randalliFourmanoir and Rivaton, 1980 were collected by first author from fish market, Bitung, North Sulawesi on Juneand September 2010. The specimens were deposited at LBRC-F, the reference collection of LIPI Bitung, TechnicalImplementation Unit for Marine Biota Conservation, Research Centre for Oceanography, Indonesian Institute ofSciences, Bitung, Indonesia. Plectranthias retrofasciatus is closely related to P. megalophthalmus and P. knappi,in sharing some morphological characters as snout length and interorbital width, while P. randalli differs to otherspecies by having a moderate deep body proportion. Initially these species known only from New Caledonia for P.retrofasciatus and Chesterfield Islands and southern Taiwan for P. randalli respectively. The two species of anthiinefishes collected from Bitung, Indonesia bringing the total number of species of this genus known in Indonesia to six."
