Problem solving is one of four abilities which has been emphasized in the 21st century. A problem type engaged to explore students' problem solving ability is non-routine problem, particularly topic geometry. This research aims to describe students' problem-solving. It is a descriptive study using qualitative approach. The result indicated that the highability subject was quite able to understand the task and look back the results. In addition, upon preparation and execution of the plan, subject was able to do well. The medium-ability subject was able to plan properly, despite quite capable of understanding the problem, carry out the plan and looking back her result. The low-ability subject figured out the problem quite well, yet during plan preparation, plan execution, and reviewed the work, subject performed adequately. It is necessary for teacher to train and familiarize the students in solving non-routine problem hence the students can experience their own mathematical process.

Penelitian ini bertujuan untuk mengetahui potensi ransum berbasis bahan baku lokal sebagai pengganti ransum komersil terhadap kadar air dan abu. Penelitian ini menggunakan bahan pakan lokal yang ada di Kabupaten Tanah Laut, Provinsi Kalimantan Selatan yang terdiri dari jagung lokal, dedak padi, bungkil inti sawit, tepung ikan, maggot, tepung batu, topmix dan juga ransum komersil. Metode penelitian ini adalah metode eksperimen menggunakan Rancangan Acak Lengkap (RAL), dengan 5 perlakuan ransum dan 4 ulangan.  Ransum perlakuan yaitu A (100 % Ransum Komersil / Kontrol), B (75 % Ransum komersil + 25 % Ransum Lokal) C (50 % Ransum Komersil + 50 % Ransum Lokal), D (25 % Ransum Komersil + 75 % Ransum Lokal) dan E (100 % Ransum Basal Lokal).  Parameter yang diukur adalah kadar air (%) dan kadar abu (%).  Hasil penelitian menunjukan bahwa kualitas nutrisi ransum lokal dan ransum pabrikan pada komposisi tertentu  memberikan pengaruh berbeda tidak nyata terhadap kadar air dan kadar abu. Dari hasil penelitian ini disimpulkan bahwa komposisi campuran ransum lokal dan ransum komersil tidak berpengaruh terhadap kandungan nutrisi terutama kadar air dan kadar abu. Kadar air berkisar 11,64% -12,38% dan kadar abu berkisar 16,14% - 16,76%.

Tujuan penelitian adalah untuk mengevaluasi kendala pengembangan ternak sapi potong di Kenagarian Batang Gasan Kecamatan Batang Gasan Kabupaten Padang Pariaman. Metode penelitian dilakukan dengan metode survey. Responden penelitian ini adalah peternak sapi potong yang berada di Kenagarian Batang Gasan, Kecamatan Batang Gasan, Kabupaten Padang Pariaman, sebanyak 74 orang. Analisis data yang digunakan dalam penelitian ini adalah analisis kuantitatif dengan pembahasan secara desktiptif. Dari penelitian ini dapat disimpulkan bahwa ada beberapa kendala dalam penggembangan ternak sapi potong di Kenagarian Batang Gasan Kecamatan Batang Gasan Kabupaten Padang Pariaman yaitu ketersediaan lahan hijauan (peternak hanya mengandalkan rumput liar), keterbatasan sarana dan prasarana seperti mesin potong rumput dan chopper, belum menerapkan formulasi ransum berdasarkan kebutuhan ternak, pakan yang diberikan tidak sesuai fisiologis ternak dan minimnya penerapan IPTEK terutama teknologi pakan seperti silase dan fermentasi hijauan.

This study aims to determine the effect of using rations based on local raw materials as a substitute for commercial rations on the production performance (ration consumption, body weight gain and ration conversion) of broilers. This study used 100 DOC without male and female separation. The cages used were box cages measuring 75x60x50 cm per unit of 20 units and each unit consisting of 5 chickens. This research method is an experimental method using a completely randomized design (CRD), with 5 ration treatments and 4 replications. The treatment rations were A (100% Commercial / Control Ration), B (75% Commercial Ration + 25% Local Ration) C (50% Commercial Ration + 50% Local Ration), D (25 % Commercial Ration + 75% Local Ration) and E (100% Local Basal Ration). Parameters measured were ration consumption (g/head/week), body weight gain (g/head/week) and broiler ration conversion. The results of the analysis of diversity showed that the provision of rations based on local raw materials as a substitute for commercial rations had a very significant effect (P<0.01) on ration consumption, body weight gain and broiler ration conversion. The results of the DMRT test showed that the provision of rations based on local raw materials as a substitute for commercial rations on ration consumption, body weight gain and ration conversion in treatments B, C and D were not significantly different from treatment A, but significantly higher than treatment E. Based on this study it can be concluded that giving 25% commercial ration + 75% local ration has the same effect as giving 100% commercial ration (control ration).
