    - This research is conducted because of the limited information of mangrove forest in Parit Belida and the damage caused by the lack of society awarness. Based on the preliminary research, those are due to the irrelevant prior knowledge and information transfer. Mangrove forest in Parit Belida provides facts on the ground and biological object materials which are relevant with the topic of ecosystem. It has various plants and animals with special morphology, various types of adaptation, and the physical characteristics of the mangrove forest itself. However those can not be directly applied to the learning process. It needs to be processed into functional materials which allows the students to understand the concept of the fact presented in the teaching materials. The R&D method was used to obtain teaching material initiated with preliminary study, composing draft, development, validation and program implementation. As Curriculum 2013 said that teaching learning process should develop character education and scientific approach for students, the concept and the attitude of the students towards the awarness of mangrove forests can be improved by involving them actively and innovatively. The development of teaching materials based on the facts and potency of local mangrove forest could create the conservation characteristic of student

    Kota Kendal merupakan daerah dataran rendah yang berada di pesisir pantai utara Laut Jawa yang sering dilanda bencana banjir, tidak terkecuali daerah-daerah di sekitar Kota Kendal. Seiring dengan terus bertambahnya jumlah penduduk di Kota Kendal dan sekitarnya akan memberikan dampak terhadapan pembangunan pemukiman yang baru yang akan mempersempit ruang resapan air. Disamping Kota Kendal dan sekitarnya yang memiliki drainase yang buruk dan banyaknya sungai yang sering meluap ketika hujan turun akan menimbulkan terjadinya banjir. Pemanfaatan Sistem Informasi Geografis (SIG) sangatlah penting, dimana kurangnya aplikasi SIG yang bisa menjelaskan, mempresentasikan objek daerah rentan banjir dari dunia nyata yang digunakan di dalam bentuk digital. Dalam penelitian ini, parameter yang digunakan adalah data kemiringan lereng, jenis tanah, jaringan drainase, curah hujan, dan penggunaan lahan tahun 2008 yang diperoleh dalam bentuk peta digital. Peta digital akan diolah dengan menggunakan software ArcGIS 9.3. Setiap data parameter akan diskoring dengan pemberian harkat dan bobot sesuai pengklasifikasiannya masing-masing yang kemudian dilakukan overlay intersect. Pada tahap akhir dilakukan validasi yang bermanfaat untuk menguji kebenaran kerentanan banjir di lapangan. Hasil akhir dari penelitian ini adalah Peta Kerentanan Banjir Kota Kendal dan Sekitarnya

JCW and CM are Funded by the European Union (ERC, WANDA, 101039452).We present the overview and first results from the North-PHASE Legacy Survey, which follows six young clusters for five years, using the 2 deg2 FoV of the JAST80 telescope from the Javalambre Observatory (Spain). North-PHASE investigates stellar variability on timescales from days to years for thousands of young stars distributed over entire clusters. This allows us to find new YSO, characterise accretion and study inner disk evolution within the cluster context. Each region (Tr 37, Cep OB3, IC 5070, IC 348, NGC 2264, and NGC 1333) is observed in six filters (SDSS griz, u band, and J0660, which covers Hα), detecting cluster members as well as field variable stars. Tr 37 is used to prove feasibility and optimise the variability analysis techniques. In Tr 37, variability reveals 50 new YSO, most of them proper motion outliers. North-PHASE independently confirms the youth of astrometric members, efficiently distinguishes accreting and non-accreting stars, reveals the extent of the cluster populations along Tr37/IC 1396 bright rims, and detects variability resulting from rotation, dips, and irregular bursts. The proper motion outliers unveil a more complex star formation history than inferred from Gaia alone, and variability highlights previously hidden proper motion deviations in the surrounding clouds. We also find that non-YSO variables identified by North-PHASE cover a different variability parameter space and include long-period variables, eclipsing binaries, RR Lyr, and δ Scuti stars. These early results also emphasize the power of variability to complete the picture of star formation where it is missed by astrometry.Peer reviewe
