Lapangan “M” terletak di Cekungan Sumatra Selatan. Target reservoir berada pada Talang Akar Formation (TAF) yang merupakan reservoir batupasir dengan lapisan keseluruhannya adalah perselingan antara batupasir dan shale serta sisipan batubara. Lapisan batupasir pada TAF memiliki ketebalan yang tipis sekitar 13.5 m dan berada di bawah tuning thicknes. Pada penelitian ini penulis mengaplikasikan metode inversi seismik deterministik dan stokastik untuk mengatasi lapisan tipis. Metoda inversi deterministik model based dijadikan model awal/ soft constraint dalam inversi stokastik. Inversi model based menghasilkan hasil yang sesuai dengan data sumur, namun hasilnya masih cenderung smooth dan blocky sehingga belum mampu meresolusi lapisan tipis dengan baik. Inversi seismik stokastik diaplikasikan untuk mengatasi kekurangan yang ada pada inversi seismik deterministik khususnya pada kasus lapisan tipis. Dari realisasi-realisasi model impedansi hasil inversi stokastik yang telah dihasilkan, penulis membuat suatu model probabilitas pada selang impedansi tertentu, dalam hal ini ialah selang impedansi batupasir sehingga penyebaran dari batupasir dapat terlihat. Model probabilitas dari 30 realisasi inversi stokastik dengan parameter P-Impedance dapat memetakan persebaran reservoir batupasir di lapangan “M” dengan cukup baik. Peta probabilitas batupasir maksimum berada pada bagian utara daerah penelitian.

Resolution capability of seismic reflection data is becoming more interesting topic to discuss even for today. Several methods and approximations to attempt bandwidth extension of seismic reflection data have been proposed in wide variety. Among them is a non-stationary reflectivity inversion based on basis pursuit decomposition technique. The need of the method is increasing as it can provide realistic resolution of seismic data. The main advantages of the method are consistancy with log data, good lateral continuity, preserve amplitude and capable in denying artificial reflection feature. Nevertheless, its computational process is very expensive thus most pratitioners tend to avoid the method and look for another method that could serve quicker instead of better results.This paper attempt to propose a set of computational scheme which can be used flexibly for any prospective user to reduce the computational cost of the method.

One of the problems on current road infrastructure development in Indonesia is the difficulty of getting road data information, for example is data for supporting sustainable road infrastructure development. Moreover, some of road authority did not realize that data is important element in the cycle process of road infrastructure development. Inaccurate road data will decrease the quality of road budgeting and programming, on the other hand it will affect the period service of road itself. The good road data could support sustainable road by providing the road value such as historical, current condition, and prediction. Indonesian Road Data Center Operations (IRODCO) is a concept of integrated road database storage. Collaborate data from Indonesian road authority (Ministry of Public Work and Housing, Ministry of Transportation, National Police and Local Government) can be stored, processed and managed to be a value- added information. IRODCO will provide various information, completely, easily and quickly for supporting the sustainable development of road infrastructure. This paper will explain the background of IRODCO concept, type of road database, the architecture, and how this concept will be implementing in Indonesia next, particularly for supporting the sustainable road infrastructure development.

Kami melakukan kajian teoretis mengenai reaksi hidrogenasi metoksida (H3CO) menjadi metanol (CH3OH) pada katalis klaster Pd6Ni secara teoretis menggunakan perhitungan berbasis teori fungsional kerapatan (DFT). Reaksi ini merupakan salah satu reaksi pembatas laju pada proses konversi gas karbon dioksida (CO2) menjadi metanol. Hasil perhitungan kami menunjukkan bahwa reaksi hidrogenasi metoksida pada katalis klaster Pd6Ni memiliki energi aktivasi yang lebih baik dibandingkan dengan energi aktivasi pada katalis konvensional berbasis permukaan Cu. Hal ini disebabkan karena klaster Pd6Ni mampu menstabilkan adsorpsi molekul metanol dengan baik dan memiliki energi adsorpsi *H yang relatif lemah.

Perdebatan tentang praktik pengelolaan limbah telah menjadi isu sangat penting, aktivitas manusia yang telah melebihi beban kapasitas asimilatif biosfer menjadi penyebabnya. Dewasa ini limbah direkomendasikan untuk di daur ulang dan dijadikan objek pemulihan energi. Pada prinsipnya limbah memerlukan pengelolaan agar tidak membahayakan lingkungan berbeda dengan produk samping yang masih bisa dimanfaatkan. Produk samping seperti kotoran sapi atau sisa bahan organik bisa dijadikan sumber energi, biogas. Namun biogas sendiri juga mengeluarkan produk samping berupa biosulry. Di Desa Cibodas terjadi pengolahan kotoran sapi berlapis dengan skema biogas dan pupuk biosulry. Pengolahan kotoran sapi berlapis ini memberikan banyak keuntungan untuk masyarakat Desa Cibodas, selain sumber energi baru juga menghasilkan sumber pendapatan baru bagi masyarakat.
