Disaster caused by both nature and human factors has resulted in the occurrence of human casualties, environmental damage, property loss, and psychological impact. The study aims to classify disaster prone areas in Indonesia using K-means clustering method implemented in rapid miner tools. The data are collected from the Central Bureau of Statistics about the number of villages that considered as natural disaster-prone by province in Indonesia in years [2008][2009][2010][2011][2012][2013][2014]. The sample data are 34 provinces in Indonesia with 3 natural disasters commonly happen i.e. namely: Flood, Earthquake and Landslide. The final outcomes of the study were: (1) 4 provinces classified as High with cluster center 1363.333 (flood), 528.25 (earthquake) and 949.583 (landslide); 14 provinces classified as Medium with cluster center 142.619 (flood), 96.071 (earthquake) and 72.048 (landslide); and 16 provinces classified as Low with cluster center 507.396 (flood), 57.604 (earthquake) and 177.479 (landslide). This work can further provide input to the Indonesia government through mapping of disaster prone areas especially 4 provinces with very high natural disasters such as Aceh,

Cold formed steel has relatively high width-to-thickness ratio elements, which causes it to buckle easily. Combining it with timber laminas would be an effective solution for reducing this buckling problem. This research focuses on the connection system of a cold formed steel-timber composite, which was obtained by attaching several timber laminas to the web part of cold formed steel using screws. The connection used two bolts that were 8 mm in diameter, as well as two different kinds of side plates: steel and plywood. Cold formed steel 75Z08 and Swietenia mahagoni (moisture content 12.2%; specific gravity 0.77) were used for connections and were loaded in parallel and perpendicular directions. In addition, the connections of cold formed steel (without timber laminas) using self-drilling screw fasteners were tested until failure. Numerical analysis predicting the load-slip curve and apparent yield load of the composite joints was carried out using the DOWEL program and the European Yield Theory, respectively. The test results showed that the connection system with steel side plates is capable of accommodating the strength increase of composite member, as it has a maximum load carrying capacity and initial slip modulus of about 4.5 and 2 times larger than those of the cold formed steel connections, respectively. In the case of a connection system with plywood side plates, its joint properties are similar to those of the cold formed steel connection, except that it has larger joint deformation.

ABSTRAK: Tanaman herbal merupakan tanaman yang sangat potensial untuk dapat dikembangkan melalui proses pengolahan yang tepat. Ibu-ibu rumah tangga RW IV Kelurahan Banyumanik Kota Semarang telah mengembangkan berbagai jenis tanaman herbal di pekarangan rumahnya namun belum mampu mengolah tanaman herbal tersebut menjadi produk yang memiliki nilai ekonomi yang lebih tinggi. Pengabdian ini bertujuan untuk memberikan penyuluhan dan pelatihan kepada ibu- ibu rumah tangga RT 01 dan RT 02 Kelurahan Banyumanik melalui pengolahan tanaman herbal menjadi bentuk produk olahan sirup dan produk instan lainnya.

Pelaksanaan kegiatan pengabdian masyarakat IbM ini telah berlangsung intensif selama 2 bulan dengan mengoptimalkan pemberian motivasi berwirausaha serta pengenalan potensi bahan herbal. Hasil pelaksanaan kegiatan pengabdian kepada masyarakat ini menunjukkan bahwa pelatihan motivasi kewirausahaan dapat mendorong keinginan warga masyarakat untuk berwirausaha di dalam meningkatkan pendapatan keluarga dibandingkan hanya mengandalkan satu pendapatan dari satu pekerjaan menjadi buruh atau pekerja. Selain itu kegiatan pelatihan pengolahan tanaman herbal menjadi produk makanan bernilai tinggi mendapat respon positif dari warga RW IV Kelurahan Banyumanik Kecamatan Banyumanik Kota Semarang.Kata kunci: Sirup, Herbal, Instant, Pengabdian, Pelatihan ABSTRACT: Herb plant is one of raw material that very potensial to develop using some processing methods. Most of housewife in RW IV kelurahan Banyumanik Semarang city, already planting some herb on their yard, but not yet process it into another product that has high economical value. The aims of this activity was to give some food processing training for the housewife in the area of RT 01 & RT 02 ( RW IV) Kelurahan Banyumanik using herb plant as the raw material. The output are guidance book of herb processing product, journal publication, and proceeding of national seminar. Some activity that was held such as herb processing demo, debriefing, and discussions. The training that already held was how to make ginger syrup and instant ginger powder. This IbM activity already held in 2 months intensively. The activity were focused on entrepreneurship motivation training and exploring the potensial value of herb.The result of this activity showed that entrepreneurship motivation training could encourage eagerness this community to increase their family income. Furthermore, herb processing training also had great response from the people of Kecamatan Banyumanik Semarang City.Keywords: Syrup, Herb, Instant, Service, Training
