In vitro propagation of pitcher plants is still limited only using seeds, while the other in vitro methods using leaf explants such as embryogenesis, organogenesis, and callus culture has not been widely reported. The research aims to study the growth response of leaf explants in two species of pitcher plants (Nepenthes gracilis and Nepenthes reinwardtiana), which formed callus in several treatment media combinations. Leaf pieces were taken from a 4-month pitcher plant culture were grown on the treatment media, namely modified media of Murashige & Skoog with a half concentration (½ MS) added 2.4-Dichlorophenoxoxyacetate (2.4-D) with a concentration of 0, 0.5, 1, 1.5, and 2 mg L-1 and kinetin (0.5 mg L-1). The treatment was then stored in a dark environment to induce callus formation. The observation for 12 weeks showed that the time of callus formation in two species of pitcher plant observed was not significantly different. Both species of pitcher plants begin to form callus in the fourth week after treatment. None of the leaf explants were planted on the control medium without hormones formed callus. The best medium for callus induction in N. gracilis is ½ MS medium added with 2 mg L-1 2,4-D and 0.5 mg L-1 kinetin, with callus morphology brownish-white with friable texture. In comparison, the optimum callus media from leaf explant of N. reinwardtiana has not been obtained yet. Thus further research is still needed. 

Di SMPN 2 Lawe Sigalagala banyak dijumpai siswa yang tidak memiliki minat dalam mempelajari matematika, sehingga menimbulkan kebosanan dan keaktifan siswa dalam mempelajari matematika kurang. Oleh karena itu, guru yang mengajar bidang studi matematika hendaknya menggunakan metode yang tepat dalam mengajar dan menumbuhkan motivasi siswa. Dengan menggunakan model pembelajaran Think Pair Share (TPS) dengan pemberian reward adalah salah satu alternatif pembelajaran untuk menumbuhkan motivasi siswa dan membangun kepercayaan diri siswa. Penelitian ini mengangkat masalah apakah model pembelajaran TPS dengan pemberian reward dapat memberi hasil yang memuaskan bagi siswa? Adapun tujuan dari penelitian ini ialah untuk mengetahui hasil belajar siswa kelas VII SMP Negeri 2 Lawe Sigalagala tentang bilangan bulat melalui model pembelajaran TPS dengan pemberian reward. Sampel yang dipilih adalah kelas VII-1 sebanyak 20 orang siswa. Materi yang diajarkan adalah bilangan bulat khususnya operasi bilangan bulat. Hasil pengolahan data didapat thitung = 2,95 dan ttabel dengan taraf signifikan  dengan dk=19 diperoleh t(0,95)= 1,73 sehingga thitung > ttabel. Ini berarti t berada pada daerah penolakan H0 dan H1 diterima. Dengan demikian dapat disimpulkan bahwa hasil belajar dengan menggunakan model pembelajaran TPS dengan pemberian reward dapat memberikan hasil memuaskan siswa.
