Pantai Sepanjang memiliki karakteristik pantai dengan substrat berupa pasir dan hamparan karang mati yang banyak ditumbuhi makroalga, merupakan habitat berbagai jenis biota, salah satunya bulu babi. Biota tersebut memiliki fungsi ekologi sebagai pemakan detritus dan pengendali populasi makroalga di ekosistem terumbu karang. Tujuan penelitian ini untuk mengetahui jenis, morfologi, anatomi, dan kelimpahan bulu babi serta hubungannya dengan parameter lingkungan. Penelitian dilaksanakan pada bulan November 2019 di Pantai Sepanjang, Kabupaten Gunungkidul. Metode sampling menggunakan stratified random sampling dengan membagi lokasi pengamatan menjadi 3 stasiun (A, B, C) berdasarkan perbedaan tutupan substrat dasar perairan. Pengamatan dilakukan terhadap jenis, morfologi, anatomi, kelimpahan dan parameter lingkungan. Hasil penelitian ditemukan 6 jenis Bulu Babi yaitu Echinometra mathaei, Echinometra oblonga, Echinothrix calamaris, Heterocentrotus trigonarius, Diadema setosum dan Stomopneustes variolaris. Enam Jenis Bulu Babi tersebut memiliki karakteristik morfologi dan anatomi yang berbeda. Kelimpahan bulu babi pada stasiun A sebesar 474 ind/ 15m2, stasiun B sebesar 611 ind/ 15m2 dan stasiun C sebesar 81 ind/ 15m2. Berdasarkan Uji korelasi  menunjukkan bahan organik sedimen berkorelasi positif, sedangkan tekstur sedimen, suhu, salinitas berkorelasi negatif  dengan kelimpahan bulu babi. Sepanjang Beach has the characteristics of sand substrates and covered by dead corals, which are overgrown by macroalgae, and is a habitat for various types of biota, one of them sea urchins. This biota has an ecological function as a detritus feeder and macroalgae population controller in a coral reef ecosystem. The aims of the study is to determine the type, morphology, anatomy, and the linkage between the abundance of sea urchins to environmental parameters. The study was conducted in November 2019 at Sepanjang Beach, Gunungkidul Regency. The stratified random sampling was applied as sampling method, by dividing the observation location into 3 stations (A, B, C) based on the difference coverage of substrate. The observation covers the type, morphology, anatomy, abundance, and the environmental parameter. There were 6 sea urchins species namely Echinometra mathaei, Echinometra oblonga, Echinothrix calamaris, Heterocentrotus trigonarius, Diadema setosum and Stomopneustes variolaris, which have different characteristics of morphology and anatomy. The abundance of sea urchins at station A is 474 ind/ 15m2, station B is 611 ind/ 15m2, and station C is 81 ind/ 15m2. The sediment organic material and the abundance of sea urchins showed a significant correlation, while sediment texture, temperature, salinity have an insignificant correlation to the abundance of sea urchins.

Goat Farming

In this study, different goat farms in Isparta province, which have considerable importance in goat farming in Turkey, were compared in terms of performance, production cost and profitability and the most profitable farm size was determined. Data were obtained by conducting a questionnaire with 92 goat farms selected by stratified random sampling method. Goat farms were divided into three groups according to their size and were then analysed. Accordingly farms were assigned as Group I (1–100 goats, 34 farms), Group II (101–300 goats, 26 farms) and Group III (>300 goats, 17 farms). It was found that small farms had higher lactation milk yield (kg/goat) and concentrate consumption (P < 0.05). It was also found that farms with higher capacity were advantageous in terms of economic criteria (P < 0.05). Results showed that as farm size increased, production cost per animal unit decreased (P < 0.05) and net profit per animal unit tended to increase (P > 0.05).
