Abstract

Perbedaan letak geografis dapat berpengaruh terhadap kadar minyak atsiri yang dihasilkan oleh suatu tanaman. Penelitian ini bertujuan untuk mengetahui perbandingan kadar minyak atsiri pelepah daun sereh dapur (Cymbopogon citratus (DC) Stapf) pada dataran tinggi di KecamatanPulosari (800 dpl) dan dataran rendah di Kecamatan Purwokerto Timur (75 dpl), serta komponen penyusun minyak atsiri tersebut. Pelepah daun sereh dapur didestilasi dengan metode destilasi uap dan air, minyak atsiri yang diperoleh diidentifikasi dengan alat kromatografi gas-spektroskopi massa (GC-MS). Hasil analisis menunjukkan perbedaan yang bermakna antara kadar minyak atsiri di dataran tinggi dan dataran rendah yaitu berturut-turut 0,152 dan 0,083% (b/b berdasarkan berat basah).Terdapat 11 komponen penyusun minyak atsiri dengan komponen dominan adalah mirsena, sitral, geranial, geranil asetat, dan sinamil asetat.Keywords: Cymbopogon citratus (DC) Stapf, sereh dapur, minyak atsiri.

Abstract

The control program of dengue hemorrhagic fever (DHF) in Indonesia is still a problem due tothe incomplete integrated handling. Sterile insect technique (SIT) for Aedes aegypti as DHFvector was considered as a potential strategy for controling the DHF. A preliminary survey wascarried out to to determine the characteristic of A. aegypti population in the study site before theimplementation of SIT. The implementation of radiation based-SIT was carried out in Krandeganand Kutabanjar Villages of Banjarnegara Regency, Central Java which involved 99 houses. Onehundred gamma rays irradiated male mosquitoes were released to each house up to five times.The eggs, larvae and adult mosquitoes were collected using ovitrap and weekly observed. Theinitial population density of A. aegipty in the studied area was obtained to be 6 mosquitoes perhouse with the mean index of house was 15.86 % and the mean sterility of sterilizedmosquitoes was 79.16 %. The SIT effectively reduced A. aegipty population after the fifthrelease of irradiated mosquitoes into the houses. It can be assumed that the SIT was effectivein controlling DHF vector in the studied area, nevertheles, it will be more effective if it iscombined with other handling techniques.

Abstract

Kepala sekolah sebagai supervisor haruslah selalu berusaha memperbaiki cara guru mengajar, cara siswa belajar, meningkatkan mutu pembelajaran dan meningkatkan hasil belajar yang bertujuan untuk memperbaiki dan mengembangkan situasi belajar dan mengajar yang lebih baik sehingga mampu meningkatkan kualitas pembelajaran, dan dapat tercapai tujuan pendidikan di sekolahataumadrasah.Pelaksanaan ideal supervisi akademik oleh kepala madrasah di MIYaspuri Lowokwaru Malang masih kurang maksimal. Hal ini dapat diindikasikan pada kenyataan bahwa supervisi belum mampu dilakukan secara berkala dan belum ada tindak lanjut dari hasil supervisi sebagai upaya perbaikan atau peningkatan kualitas pembelajaran. Penelitian yang dilakukan dengan menggunakan penelitian tindakan, yaitu Penelitian Tindakan Sekolah. Berdasarkan hasil yang diperoleh dari pelaksanaan tindakan pada siklus I dan siklus II, dapat dilihat bahwa ada kenaikan nilai yang diperoleh dari masing-masing guru kecuali untuk seorang guru. Bila dibandingkan nilai yang diperoleh secara rata-rata pada siklus I adalah 74.29, dan nilai yang diperoleh pada siklus ke II rata-rata sebesar 79.38 maka mengalami kenaikan yang cukup signifikan, yaitu sebesar 5.09. Artinya dengan pelaksanaan supervisi, mengalami peningkatan nilai rata-rata guru sebesar 5,09, dengan demikian dapat disimpulkan bahwa supervisi akademik dapat meningkatkan kompetensi guru, terutama dalam kompetensi pedagogik dan kompetensi profesional.

Abstract

The presence of malarial pigment (haemozoin) due to Plasmodium infection is a common histopathological effect in mouse liver. Previous research showed that by using a polarized light microscope, researchers were better able to detect haemozoin in mouse liver histology section. Thus, the aim of this research was to compare the haemozoin area observed by a conventional vs. simple polarized light microscope by using image processing analysis. A total of 40 images produced from both conventional light microscope and simple polarized light microscope were collected. All images were analyzed using ImageJ 1.47 software to measure the haemozoin areas. Our results showed that non birefringent haemozoin and birefringent haemozoin area was significantly different. This was because when using conventional light microscope the brown area that contained images of non birefringent haemozoin images also contained Kupffer cells which appeared as the same brown color as haemozoin. In contrast, haemozoin gave bright effect and can be easily differentiated with Kupffer cells in the birefringent haemozoin images. This study concluded that haemozoin detection in mouse liver histology using a simple polarized light microscope was more accurate compared to that of conventional light microscope.
