There is gravity measurement that is supported by magnetic measurement in Sangon to identify porphyry body and geological structure as low sulfidation epithermal system control. The survey area is 6.4 x 5.6 km for gravity method and 2.5 x 1.2 km for the magnetic method. The value of gravity anomaly after flat plane reduction processing is 122-142 mGal which is positive anomaly located in the north-eastern area and negative anomaly to 82- 102 mGal located in the south-western area. Whereas the magnetic residual anomaly is - 800-1300nT.Conducted 2.5 D modelling of gravity method that is based on local anomaly slice. The result of 2.5D modelling show that an intrusion body interpreted as Dacite intrusion as host rock which plays a role as a heat source of the mineralization system. The density of Dacite is 2.70 gr/cm3. The result of gravity modelling has a correlation with the result of magnetic modelling. Based on magnetic modelling, the intrusion body is located in the south-west.

Penelitian ini bertujuan mendeskripsikan penerapan model MMP (Missouri Mathematic Project) berbantuan modul etnomatematika dapat meningkatkan kemampuan dan keterampilan pemecahan masalah matematis siswa pada mata pelajaran matematika, serta seberapa besar keterampilan mengajar guru dapat meningkat melalui model MMP (Missouri Mathematic Project) berbantuan modul etnomatematika. Teknik pengumpulam data yang digunakan dalam penelitian ini terdiri dari tes dan non tes. Hasil penelitian terdapat peningkatan yang meliputi kemampuan pemecahan masalah matematis siswa siklus I (70%) meningkat menjadi (85%) siklus II, kemudian terjadi peningkatan pada keterampilan mengajar guru siklus I (78%) meningkat menjadi (91%) siklus II, dan keterampilan pemecahan masalah matematis siswa juga terjadi peningkatan pada siklus I (65%) menjadi (95%) siklus II. Hal ini membuktikan bahwa penerapan model pembelajaran MMP (Missouri Mathematic Project) berbantuan modul etnomatematika dapat meningkatkan kemampuan dan keterampilan pemecahan masalah matematis serta keterampilan mengajar guru

Resort Pemangku Hutan (Forest Manager Resort) or RPH Tambak is one of the forests managed by Indonesian State Forestry Enterprise in the northern part of Lawu Mountain, Surakarta. RPH Tambak located in the Berjo village, in Ngargoyoso, Central Java. This area offers ecotourism attraction for locals and international tourists. The management of forest becomes the main focus with involvement from the locals and stakeholders. This area is a potential area for avian conservation although this area is still relatively unknown. Because of its virgin forest and natural landscape, RPH Tambak has the potential to become a birdwatching spot. The aim of this research is to gather data about local avian species, to interpret the initial data for ecotourism, and to make a birdwatching track. The research methods used in this research are by tracking, and surveying the local avian species to create a roadmap for birdwatching track. The finding of this research is there are 40 species of birds from 25 families living along as cosmopolite and rarely in the birdwatching track. The birdwatching track has 5 posts with different specifications (vegetation, altitude, and tracking time) and tracking distance to make various contact with local avian species. The birdwatching track will be maintained by locals that has the access to the peak of the Lawu Mountain.
