Published: July 2019

Kesulitan belajar matematika dapat dialami oleh siswa dengan tingkat kemampuan manapun dari kalangan atau kelompok manapun. Tujuan penelitian ini adalah untuk mendeskripsikan persepsi guru matematika berstatus sertifikasi terhadap kesulitan belajar matematika siswa pada SMP Negeri. Penelitian ini menggunakan pendekatan kualitatif yang bersifat deskriptif dengan teknik pengumpulan data nontes melalui kuesioner terbuka, dan wawancara. Hasil penelitian menunjukkan bahwa persepsi guru Matematika mengenai penyebab kesulitan belajar dominan mengungkap penyebab psikologis, di antaranya rendahnya minat atau motivasi sebagai penyebab kesulitan belajar Matematika siswa; persepsi guru Matematika mengenai gejala yang menjadi indikator adanya kesulitan belajar Matematika yang paling banyak diungkap adalah rendahnya kemampuan siswa dalam menyelesaikan tugas-tugas yang diberikan oleh guru; dan persepsi guru mengenai cara yang dilakukan untuk menyelidiki adanya kesulitan belajar Matematika yang paling umum dilakukan adalah melalui dokumentasi dengan melihat hasil tes atau tugas masing-masing siswa.

Abstract: Prevention and control of cross infection is very important for dental health workers, especially in dental extraction because this action is directly related to blood and saliva. The risk of infection requires thorough attention of dental health workers. This study was aimed to determine the level of prevention and control of cross infection in dental extraction at Dental Clinic of Siloam Hospital Manado. This wass an observational descriptive study, with a total samples of 30 operators. The results showed that the prevention and control of cross infection before dental extraction performed was 61.71%; during dental extraction was 73.34%; and after dental extraction was 92.08%. Generally, the prevention and control of cross infection in dental extraction only achieved 75.71%. In conclusion, the prevention and control of cross infection in dental extraction at Siloam Hospital, Manado was still below maximum level.Keywords: prevention control of cross infection, dental extraction Abstrak: Pencegahan dan pengendalian infeksi silang merupakan hal yang sangat penting bagi tenaga kesehatan gigi, terlebih lagi pada ekstraksi gigi, karena tindakan ini berhubungan langsung dengan darah dan saliva.

B. cereus strains were isolated from three district of North Sulawesi. The B. cereus strains are potentialindigenous bacteria for biological control agent against P. xylostella. The B. cereus strains were isolatedusing Ohba and Aizawa methods. Two hundred and two isolates putatively were isolated and identifiedas member of species B. cereus. Subseguently, representing isolates were selected to be screened forthe ability to kill P. xylostella. The screening test was conducted by using leaf depped methods with theconcentration of 1,22x108 spore/ml. The potential to kill test insect was assessed by mortality value. Theresult indicated that 10 isolates out of 15 of could produce mortality of insect from 50 to 100% afterexposure of 96 hours. It was confirmed that based on symptoms produced as well as bacterialcharacteristics reisolated from cadaver of test insect, the death of the test insects was certainly causedby application of bacterial isolates. It could be concluded that indigenous bacterial isolates identified tobe member of B. cereusare potential for biological control agent against P. xylostella.

ABSTRACT The problem in postharvest pests must be handled seriously since recent research were not comprehensively resolved it. Sitophilus oryzae was a major pest and serious problem on post harvest products. The reseach aimed to develop a life table of S. oryzae on rice. The life table is a part of life history that consists of important information about the living organism. This information can be used for predicting population growth. By developing life table database, information on mortality, life expectancy, and the development ability of S. oryzae can be obtained. Results showed that mortality index of eggs was 0.4; larvae was 0,54, and pupae was 0,32, and adult was 1,0. Life expectancy index of eggs was 1.65; larvae was 1.42; pupae was 1.51 pupae; and adults was 1.0. One female was able to give rise 32.56 females or 58.57 males and females of the next generation.

ABSTRACT This study was carried out in the laboratory and in the field at City of Bitung, Districts of Minahasa. The cause of disease was studied in the laboratory and the percentage of insidence of disease was carried out in the field. Results showed that the cause of antracnose disease in North Sulawesi was Colletotrichum gloeosporioides (Penz.) Penz & Sacc. in Penz (Cg). Computation of the antracnose disease insidence showed that variety white hot chili has the highest disease insidence which is 16.50% followed by green hot chili 10.13%, and the lowest is curled chili which is 9.03%. The different in this rate is affected by pathogen, host plant and the environment. Field observation showed that this disease has already spread at all chili plantation at the City of Bitung and District of Minahasa. Keywords: Chili, antracnose, Colletotrichum gloeosporioides

ABSTRACT The research was aimed to prove the effectiveness of seed extract pangi (Pangium edule Reinw.) In increasing mortality of rice-weevil or logong (Sitophylus oryzae L.) using the solvent n-hexane fraction and the fraction of ethanol, and then evaporated with a rotary evaporator to obtain viscous extract. This research was conducted in the Chemistry Laboratory of MIPA Manado State University and mini green house Gapoktan Pinaesaan Tonsealama Village during the months of January, February and March 2012 using an experimental method in a plastic box using Completely Randomized Design (CRD) with six treatments were repeated four times, so the total experimental units were 24 units. Each plastic box filled with 20 of rice-weevil or logong adult and any treatment administered doses of: 2.5 ppm, 5.0 ppm, 7.5 ppm, 15 ppm, 30 ppm and 45 ppm. The results indicate that pangi seed extract is very effective in improving mortality of rice-weevil or logong, where the concentration of the extract 45 ppm is the best pangi seed extract. Test results of Phytochemical Test showed that secondary metabolite of pangi seed extract with n-hexane solvent contains alkaloid compounds and pangi seed extract with ethanol solvent containing phenolic compounds, saponins and tannins. Keywords : extracts, maseration, Pangium edule Reinw., Sitophylus oryzae L., n-heksan fraction, ethanol fraction, bioinsecticide ABSTRAK Penelitian ini bertujuan untuk membuktikan efektifitas ekstrak biji pangi (Pangium edule Reinw.) dalam meningkatkan mortalitas kumbang logong dengan menggunakan pelarut fraksi n-heksan maupun fraksi etanol, kemudian dievaporasi dengan rotary evaporator guna mendapatkan ekstrak kental. Penelitian ini dilaksanakan di laboratorium kimia FMIPA Universitas Negeri Manado dan mini green house Gapoktan Pinaesaan Desa Tonsealama selama bulan Januari, Februari dan Maret 2012 dengan menggunakan metode eksperimen pada kotak plastik menggunakan rancangan acak lengkap (RAL) dengan 6 perlakukan yang diulang sebanyak 4 kali sehingga total unit percobaan sebanyak 24 unit percobaan. Masing-masing kotak plastik diisi dengan 20 ekor kumbang logong dewasa dan setiap perlakuan diberikan dosis 2,5 ppm, 5,0 ppm, 7,5 ppm, 15 ppm, 30 ppm, dan 45 ppm. Hasil penelitian menunjukkan bahwa ekstrak biji pangi sangat efektif dalam meningkatkan mortalitas hama kumbang logong dimana pada konsentrasi ekstrak sebesar 45 ppm merupakan konsentrasi ekstrak biji pangi yang terbaik dalam penelitian ini. Hasil pemeriksaan uji fitokimia menunjukkan bahwa metabolit sekunder dari ekstrak biji pangi dengan pelarut n-heksan mengandung senyawa alkaloid dan ekstrak biji pangi dengan pelarut etanol mengandung senyawa fenol, saponin dan tanin.
