Judul: Studi Peluang Agroindustri Sirup Aren Berbasis Sumber Daya di Kabupaten Cianjur -  Jawa Barat
Abstrak: Upaya pemulihan perekonomian nasional antara lain dapat dilakukan dengan memberikan prioritas pada agroindustri, sehingga memberikan nilai tambah bagi hasil pertanian. Salah satunya adalah meningkatkan nilai tambah dari produk tanaman aren yaitu pengolahan nira aren menjadi simp aren. Cianjur adalah salah satu daerah potensial bagi tanaman aren dengan luas areal tanaman aren yang menghasilkan (TM) pada tahun 1997 sebesar 1.441,5 hektar dengan produksi gula merah sebanyak 1.513.575 kg.

Judul: Potential Estimation of Aren (Arenga pinnata (Wurmb) Merr.) in Cimantaja Resort, Mount Halimun Salak National Park
Abstrak: Aren memiliki kelimpahan yang dapat dijumpai di kawasan Resort Cimantaja, dimana seluruh tegakan yang ada di Resort Cimantaja merupakan tegakan yang tumbuh secara alami/liar, tanpa adanya kegiatan penanaman atau budidaya. Tujuan dari penelitian ini adalah untuk mengestimasi potensi tegakan aren terhadap regenerasi dan produktivitasnya, mengidentifikasi pola akses masyarakat dalam pemanfaatan aren, serta menganalisis saluran pemasaran gula aren. Metode yang digunakan dalam menduga potensi adalah wawancara dan inventarisasi tegakan. Hasil penelitian ini menunjukkan bahwa potensi tegakan dari tingkat tiang dan pohon belum menghasilkan cukup besar dengan persentase 84% merupakan pohon produktif. Pada inventarisasi tegakan, tingkat regenerasi menurun dari tingkat semai hingga pohon dengan kategori lestari. Produktivitas tegakan ditinjau dari kelas umur dan waktu, total potensi gula aren dari 4 desa yang terbesar adalah pada kelas umur 12-15 tahun sebesar 100.933 kg/tahun dengan jumlah 189 pohon, namun total produksi dari rentang umur 8-11 tahun memiliki persentase 56% dari total produksi. Akses pemanfaatan dilakukan di dalam dan di luar kawasan yang berdasarkan lahan garap dan status hak milik. Saluran tataniaga gula aren yang diwakili oleh Desa Cikarae Thoyybah yang menunjukkan bahwa saluran langsung (tingkat 0) memberikan keuntungan yang maksimal bagi petani. Kesimpulan dari penelitian ini adalah kelimpahan aren di Resort Cimantaja ini memiliki potensi jumlah, regenerasi serta produktivitas yang cukup baik dengan akses pemanfaatan yang telah diatur sesuai dengan tempat tumbuh tegakan serta saluran tataniaga yang cukup efisien yang ditunjukan dengan adanya saluran yang melibatkan pengumpul., Aren has an abundance that can be found in the Cimantaja Resort area, where all stands in the Cimantaja Resort are stands that grow naturally/wildly, without any planting or cultivation activities. The objectives of this study were to estimate the potential of aren stands for regeneration and productivity, identify regeneration access patterns in the use of aren, and analyze the marketing distribution of aren sugar. The methods used in estimating the potential were interviews and inventory of stands. The results of this study show that the potential of stands from the stake and immature tree levels is sufficiently large with a percentage of 84% being productive trees. In the stand inventory, the regeneration rate decreased from seedling to tree level with a sustainable category. Stand productivity in terms of age class and time, the total potential of palm sugar from 4 villages is the largest in the age class of 12-15 years at 100,933 kg/year with 189 trees, but the total production from the age range of 8-11 years has a percentage of 56% of the total production. Access to utilization based on cultivated land and private status is inside and outside the area. The palm sugar trade chain represented by Cikarae Thoyybah Village shows that the direct chain (level 0) provides maximum profit for farmers. The conclusion of this study is that the abundance of aren in Cimantaja Resort has the potential for number, regeneration and productivity that is sufficient, with access to utilization that has been regulated according to the place of growth of the stand and a sufficiently efficient trade chain that is shown by the involvement of middlemen.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
