Mango is a fruit that is very popular with the community, especially in Semarang. The taste is sweet, refreshing and has a high vitamine content is the reason this fruit has become one of the superior fruit. In the Semarang area there are quite a lot of mango trees with various varieties. These various mango varieties are potential genetic resources that need to be preserved. This study aims to explore the various mango tree varieats that grow in the municipal area of Semarang. Research techniques by exploring in 3 districts are Banyumanik, Tembalang  and Gunung Pati. The results showed 14 varieties of mango and the most widely grown varieties by the people in the municipality of Semarang are arum manis and manalagi mango. Some of them are local mangoes, mango cultivation and imported mangoes. Local varieties of mango are only found in very small quantities and have begun to scarce, so it is feared that the supply of mango germplasm is increasingly depleting. Germplasm of local mango plants is important to be preserved as a wealth of genetic resources in the Municipality of Semarang

Forests are ecosystems that have very potential natural resources, including storing high genetic resources. One of the things that threatens the decline of genetic resources in the forest is the presence of invasive species. This study aims to determine the species of invasive plants and their abundance in the Penggaron tourism forest of Ungaran Regency, Central Java. The research method was carried out by exploring the entire forest area through the path. The results of the study showed that 13 species of invasive plants were included in 7 families. The most number of invasive plants from the Poaceae family include 5 species : Axonopus Compressus, Cynodon dactylon, Pennisetum purpureum, Paspalum conjugatum and Eleusine indica. The highest relative abundance was Eleusine indica and was followed by Synedrella nodiflora, Elephantopus scaber and Paspalum conjugatum. The species of invasive plants, especially the abundant ones, need to be controlled by the population so as not to threaten native plants and cause environmental degradation in Penggaron tourism forests. Key word : Invansive plant, Penggaron tourism forest, genetic resources.

Pendekatan, strategi, metode, dan teknik pembelajaran pada hakikatnya dapat dibedakan tetapi tidak dapat dipisahkan. Keempat istilah tersebut merupakan satu kesatuan dalam pembelajaran. Pendekatan, strategi, metode, dan teknik pembelajaran yang akan dan/atau sedang digunakan dapat diketahui dari langkah-langkah pembelajaran yang telah tersusun dan/atau sedang terjadi. Pendekatan pembelajaran adalah cara umum dalam memandang pembelajaran. Sedangkan strategi pembelajaran adalah ilmu dan kiat di dalam memanfaatkan segala sumber belajar yang dimiliki dan/atau yang dapat dikerahkan untuk mencapai tujuan pembelajaran yang telah ditetapkan. Metode mengajar adalah berbagai cara kerja yang bersifat relatif umum yang sesuai untuk mencapai tujuan pembelajaran tertentu dan teknik pembelajaran adalah ragam khas penerapan suatu metode sesuai dengan latar penerapan tertentu. Teknik pembelajaran mengambarkan langkah-langkah penggunaan metode mengajar yang sifatnya lebih operasional. Faktor-faktor yang perlu diperhatikan dalam penentuan teknik pembelajaran di antaranya adalah kemampuan dan kebiasaan guru, ketersedian sarana dan waktu, serta kesiapan siswa. Faktor-faktor yang perlu dipertimbangkan dalam memilih strategi pembelajaran ialah tujuan pembelajaran, jenis dan tingkat kesulitan materi pelajaran, sarana, waktu yang tersedia, siswa, dan guru.
