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: Studi Populasi dan Habitat Monyet Ekor Panjang (Macaca fascicularis) di Cagar Alam Pananjung Pangandaran Jawa Barat
Abstrak: Pananjung Pangandaran Nature Reserve is one of natural habitat for long-tailed macaque (Macaca fascicularis). This wildlife was listed as Least Concern status in IUCN (2013) and Appendix II in CITES. The result of the research, which was done in three observation tracks, showed a different density of long-tailed macaque. The greatest population density was found as Karang Pandan (22 ind/ha), while at second track (Tadah Angin) were 4 individuals/ha, and at the third track (Cikamal) there were 19 individuals/ha. The range of population at the first track as many as 22 ± 9 individuals, at the second track as many as 4 ± 2 individuals, and third track as many as 7 ± 4 individuals. The adult long-tailed macaque was found at most in this research. Sex ratio of long-tailed macaque at the first and third track was 1:4, and at the second track was 1:3. There were 48 plant species that were found in the area where the long-tailed macaque carried out their activity, and 22 of the species had potential for long-tailed macaque feed.

Judul: Pembuatan Sistem Kontrol Gas Amonia Berbasis Mikrokontroler Arduino.
Abstrak: Gas amonia adalah salah satu gas yang beracun yang dapat meneyebabkan kematian pada manusia atau hewan. Dalam penelitian ini dibangun sebuah sistem pengontrol yang dapat mengatasi bahaya keracunan akibat adanya gas amonia. Sistem pengontrol dibuat menggunakan dan menggunakan relay sebagai saklar otomatis untuk kipas, kipas yang digunakan sebagai pembuang gas amonia, sensor MQ-135 sebagai sensor pendeteksi keberadaan konsentrasi gas amonia dalam satuan part per million (ppm). Sistem pengontrol beroperasi menggunakan arduino uno untuk mengirim perintah on/off otomatis pada relay sebagai saklar otomatis dari kipas, ketika sensor membaca konsentrasi gas diatas 5 ppm maka peintah yang dikirim adalah on kemudian kipas akan menyala dan apabila dibawah 5 ppm perintah yang dikirim adalah off kemudian kipas mati.
