Judul: Kondisi Anatomis Gigi dari Tulang Kepala Kuda di Laboratorium Anatomi Fakultas Kedokteran Hewan Institut Pertanian Bogor
Abstrak: Penelitian ini bertujuan mengetahui struktur dan susunan gigi normal dan abnormal pada preparat kepala kuda di Laboratorium Anatomi Fakultas Kedokteran Hewan Institut Pertanian Bogor. Penelitian dilakukan dengan mengamati struktur gigi rahang atas dan bawah dari 8 kepala kuda. Hasil pengamatan anatomis gigi kemudian dikategorikan berdasar berbagai literatur. Dari basil penelitian diketahui bahwa kisaran umur preparat kuda antara 1- 2 tahun dan 10 - 25 tahun. Kelainan bentuk gigi terlihat pada kuda umur tua. Kelainan bentuk gigi terdiri dari diagonal bite, ventral curvature, uneven teeth, diastema, stepped molar, wave, ramp, accentuated transverse ridges, enamel points, dan sheared molar table.

Judul: Studi abnormalitas gigi pada kuda delman di Kota Bogor
Abstrak: Delman horse is one of the working animal that commonly used by the Bogor citizen as today tour transportation. Research on delman horse has not been done, including the dental health. The aim of this study is to identify and describe dental abnormalities on delman horses in Bogor city. This research was conducted in two stage, which are filled the questionnaires and interviewed with coachmen and also examined delman horse’s teeth. The results showed that horses have 100% bit sore, 80% sharp enamel points, and 30% mouth laceration. Incisors abnormalities were 20% overjet and 10% underjet. Canine abnormalities were 30% canines cutted and 10% canine periodontitis. Wolf teeth owned by 50% of examined horse. Cheek teeth abnormalities were 10% stepped mouth, 30% wave mouth, and 60% cupped out. Hooks formed 10% at the rostral cheek teeth, 30% caudal, and 30% rostrocaudal. Dental abnormalities in delman horses mostly considered as minor and closely related to the bit size, horse’s age, feed, others dental abnormalities, human manipulation, and genetic.

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.
