Judul: Fenotipe saluran ceerna beruk (Macaca nemestrina) sebagai hewan model penelitian
Abstrak: Pig-tailed macaques (Macaca nemestrina) are primates where its original habitat is on the island of Sumatera, Indonesia. The local name in Indonesia is Beruk. Beruk has special characters, with big body and steady walk on four legs and has already obvious its sexual dimorphism. The Beruk has a tail which is about 1/3 part of its body length while its head has no diceernible neck. Its has brown fur.

Judul: Long-tailed Macaque (Macaca fascicularis) Morphometry on Tinjil Island
Abstrak: Monyet ekor panjang (Macaca fascicularis) banyak digunakan dalam riset biomedis sebagai hewan model. Salah satu lokasi konservasi M. fascicularis di Indonesia terletak di Pulau Tinjil, Provinsi Banten. Pulau Tinjil termasuk jenis Natural Habitat Breeding Facility (NHBF). Penelitian ini menggunakan 40 ekor MEP di pulau Tinjil dan 30 ekor MEP di fasilitas penangkaran Pusat Studi Satwa Primata. Parameter morfometri mencakup bobot badan, panjang badan anterior, total tinggi kepala, panjang lengan atas, panjang lengan bawah, lebar dada, tebal dada, lebar pinggang, panjang paha, dan panjang betis. Uji Mann-Whitney digunakan untuk membandingkan morfometri MEP di Pulau Tinjil berdasarkan umur dan jenis kelamin. Hasil penelitian menunjukkan bahwa perbedaan ukuran morfometri sangat terlihat pada usia dewasa antara jantan dan betina. Selain itu, perbedaan juga terlihat secara signifikan antara kelompok jantan usia pra-dewasa dan dewasa. M. fascicularis yang berhabitat di pulau Tinjil relatif lebih kecil dibandingkan dengan studi-studi sebelumnya, namun dalam beberapa kategori usia masih masuk dalam rentang ukuran tinggi duduk dan berat badan., Long-tailed macaque (Macaca fascicularis) are widely used in biomedical research as animal models. One of the conservation sites in Indonesia is located on Tinjil Island, Banten Province. Tinjil Island is a Natural Habitat Breeding Facility (NHBF). Research about morphometry of long-tailed macaque on this island is still minimal. This study used 40 macaques on Tinjil Island and 30 macaques in the Primate Animal Study Center captive facility. Morphometric parameters include body weight, anterior body length, total head height, upper arm length, forearm length, chest width, chest thickness, waist width, thigh length, and calf length. The Mann-Whitney test was used to compare morphometry of Macaca fascicularis on Tinjil Island based on age and sex. The results showed that differences in morphometric size were very visible in adulthood between males and females. In addition, significant differences were also seen between groups of pre-adult and adult males. M. fascicularis which lives on Tinjil Island is relatively smaller compared to previous studies, but in several age categories it still falls within the range of sitting height and body weight.

Judul: Sulfonated Polystyrene-Nafion Composite Gel Polymer Electrolyte for Dye Sensitized Solar Cells Application with Synthetic Dyes
Abstrak: Dye Sensitized Solar Cell (DSSC) merupakan sel surya generasi ketiga dengan kelebihan mudah difabrikasi, biaya produksinya rendah, ramah lingkungan, serta menghasilkan efisiensi konversi daya yang cukup baik. Sistem DSSC tersusun atas elektrode kerja, zat warna, elektrolit, dan elektrode lawan. Elektrolit yang umum digunakan dalam aplikasi DSSC adalah elektrolit cair yang mengandung iodida/triiodida (I-/I3-). Elektrolit cair memiliki kelemahan mudah menguap, sehingga mengakibatkan kinerja DSSC menjadi menurun. Penelitian ini bertujuan memodifikasi elektrolit cair menjadi gel polimer elektrolit komposit polistirena tersulfonasi-nafion serta membandingkan nilai efisiensi dari penggunaan zat warna merah dan kuning sebagai zat pemeka DSSC. Komposit polistirena tersulfonasi-nafion dibuat dengan lima variasi komposisi 0,00:1,00; 0,25:0,75; 0,50:0.50; 0,75;0,25; 1,00: 0,00. Hasil pengukuran menunjukkan komposisi optimum komposit polistirena tersulfonasi-nafion adalah 0,50:0,50 dengan nilai efisiensi 1,50% untuk zat warna merah dan 1,35% untuk zat warna kuning., Dye Sensitized Solar Cell (DSSC) is a third generation solar cell with the advantages of being fabricated, low production costs, environmentally friendly, and producing a fairly good power conversion efficiency. The DSSC system consists of a working electrode, dyes, electrolyte, and counter electrode. The electrolyte commonly used in DSSC applications is liquid electrolyte containing iodide/triiodide (I-/I3-). The electrolyte has the weakness of being volatile, which causes the performance of the DSSC to decrease. This study aims to modify the liquid electrolyte into a gel polymer electrolyte composite PSS-nafion and compare the efficiency values of red and yellow dyes as DSSC sensitizers. Sulfonated polystirene-nafion composite was made with five composition variations 0,00:1,00; 0,25:0,75; 0,50:0,50; 0,75;0,25; 1,00: 0,00. The measurement results show that the optimal composite composition of PSS-nafion is 0,50:0,50 with an efficiency value of 1,50% for red dyes and 1,35% for yellow dyes.
