Something interesting about the findings of the human skeleton in Binangun and Leran Prehistoric Burial Sites is the modification of the human teeth that is extremely rare found in prehistoric grave in Java as well as in Indonesia. Such tradition is still practiced in Java and Bali by leveling the top or bottom front teeth (Jawa: pangur tradition). Forms of human teeth of Binangun, Leran 1 and Leran 2 are very unique, teeth of Binangun is tapered while human teeth of Leran 1 and Leran 2 shaped like a flower bud. Anatomically the shape of teeth can be altered by a person in the habit of using his teeth. But variations in tooth shape as found in individuals in the Binangun and Leran sites, Rembang regency, Central Java province, in general is the result of a tribal culture.

Generally in Indonesia and especially in Java, until now, in ABSTRAKDi Indonesia pada umumnya dan Jawa khususnya, selama ini diketahui bahwa dolmen banyak ditemukan di Jawa Timur, yaitu di Bondowoso dan Besuki. Akhir-akhir ini diketahui bahwa dolmen ditemukan pula di daerah Kabupaten Banyuwangi. Salah satu monumen dari tradisi megalitik ini ditemukan di kawasan PT. Perkebunan Nusantara XII Malangsari, Banyuwangi, Jawa Timur. Berdasarkan informasi dari masyarakat setempat diperkirakan bahwa kawasan Perkebunan Malangsari merupakan situs kubur dolmen. Secara fisik, konstruksi dolmendolmen di kawasan ini hanya sedikit mengalami gangguan karena tertimbun tanah antara 50 -60 cm dan tertutup kebun kopi milik PT. Perkebunan Nusantara XII. Namun, rupanya sebagian dari dolmen tersebut telah digali oleh masyarakat yang bertujuan mencari harta karun. Mereka mampu membuka kubur dolmen cukup dengan membuka sebuah batu tanpa membongkar konstruksinya. Dolmen temuan hasil ekskavasi di Petak D 55 Blok Sidomaju, Afdeling Mulyosari, Malangsari, secara fisik dan konstruksi masih terlihat utuh, tetapi baik sisa rangka manusia maupun artefak bekal kuburnya tidak ditemukan. Keadaan semacam ini menunjukkan kemungkinan bahwa dolmen ini pernah dibuka. Luasnya areal sebaran serta belum dilakukannya penelitian secara menyeluruh, menjadikan dolmen Malangsari sebagai objek baru yang sangat menarik untuk diteliti lebih lanjut. Kelak di kemudian hari objek baru ini penting untuk dikaji baik bagi perkembangan penelitian arkeologi, maupun untuk kepentingan pengelolaan sumberdaya arkeologi di Indonesia.Kata Kunci: PTPN XII Malangsari, dolmen, situs kubur dolmen, data baru.

Petrographic analysis is able to explain about the technology of pottery making, where the pottery come from and how to the pottery spread out. Petrographic analysis of sherds found either from the surface survey and excavations in the region of Bethok and Grati Lakes, can indicate whether the pottery found at the sites above have similar elements with the pottery marketed in the local market nowadays?. Based on the results of petrographic analysis can be concluded that the fragments of pottery found at both sites above have similar material elements of pottery now found in the local markets. Thus since long time ago pottery marketing from Besuk village production have reached the regional Tiris market within about 50 Km. Similarly, the pottery artefacts found at the Grati Lake are assumed to have originated from Keraton village production around 50 Km from the site.

Lately, the decline in the understanding of Pancasila and Bhinneka Tunggal Ika as the identity and ideology of the Indonesian nation has become a central issue that we must solve together. Diversity in ethnicity, religion, race, and customs owned by the Indonesian nation has been perceived and understood since thousands of years ago, diversities which were starting to be joined together during the Majapahit era. Mpu Tantular in his infamous Kakawin Sutasoma has written "bhinneka tunggal ika tan hana dharma mangrwa", an idea about unity in diversity. From then on, this idea has grown into nationalism spirit, which eventually became a tremendous force to repel the Dutch colonialist. Therefore these diversities must be maintained and preserved. Through a study about the past, archaeology has a role in protecting and preserving the cultural diversity to unify the nation.

Study of Neolithic settlement pattern in Ranu Grati area at Pasuruan-East Java is a part of research series on the ancient settlements at the lakes area in East Java ABSTRAKStudi pola permukiman neolitik di kawasan danau Ranu Grati, Pasuruan, Jawa Timur merupakan rangkaian penelitian permukiman masa lampau di kawasan danaudanau di Jawa Timur yang dilakukan oleh penulis sejak tahun 2008. Penelitian dilakukan secara berturut-turut setiap tahun yang dimulai dari kawasan danau Ranu Klakah, Ranu Gedang, Ranu Segaran, Ranu Bethok, dan terakhir Ranu Grati. Sekalipun baru dimulai, penelitian di kawasan Ranu Grati telah menghasilkan data tentang permukiman masa lampau yang cukup siknifikan, baik data geo-arkeologi atau arkeologi lansekap maupun data artefaktualnya. Data geo-arkeologi seperti teras-teras danau sedangkan temuan artefak antara lain berupa fragmen tembikar, bandul jala, dan beliung merupakan bukti adanya permukiman di kawasan danau Ranu Grati.
