Lumpur geotermal yang dihasilkan dari proses operasi Pembangkit Listrik Tenaga Panas Bumi Dieng mengandung silika amorf sebesar 50 %, yang sangat potensial untuk dijadikan sumber kebutuhan silika amorf untuk dunia industri. Penelitian ini bertujuan untuk mempelajari kinetika pelarutan silika amorf dari lumpur panas bumi dengan menvariasikan variabel – variabel yang mempengaruhinya. Pada penelitian ini, alkali-solubilization yang merupakan proses pelarutan silika dalam larutan NaOH dalam labu berpengaduk dipelajari dengan memvariasikan variabel suhu (50 – 90 °C), kecepatan pengadukan (150 – 450 rpm), perbandingan molar Na/Si (2 – 8), dan ukuran diameter padatan (0,0069 – 0,01975 cm). Hasil penelitian menunjukkan bahwa laju pelarutan silika amorf dari limbah geotermal meningkat dengan naiknya suhu dan kecepatan pengadukan. Namun, ukuran padatan dan perbandingan molar pereaksi tidak menunjukkan pengaruh yang berarti terhadap proses pelarutan. Kata kunci: lumpur geotermal, silika amorf, alkali-solubilization, kinetika pelarutan Dieng’s geothermal power plant generates not only energy but also wastes as sludge that contains around 50% silica in an amorphous state. The waste has a great potential to be used as a source of micro-amorphous silica synthesis to fulfill industrial needs. This research aimed to study the dissolution kinetics of amorphous silica. In the present work, the alkali – solubilization process by means of the dissolution of amorphous silica in an agitated flask was studied by varying process temperatures (50 – 90C), stirring speed (150 – 450 rpm), Na/Si molar ratio (2 – 3), and silica particle size (0,0069 – 0,01975 cm). Experimental results showed that the rate of geothermal silica dissolution increased with temperature and stirring speed. Meanwhile, Na/Si molar ratios and silica particle sizes showed no significant influence on the dissolution process. Calculation results indicated that the dissolution process involved a solid – liquid reaction that occured at the solid surface. Keywords : geothermal sludge, amorphous silica, alkali-solubilization, dissolution kinetics

ABSTRAKPerjalanan reintegrasi Aceh dimulai sejak tahun 2006-2012 melalui sebuah badan sementara (ad hoc) yang dikenal dengan Badan Reintegrasi Aceh (BRA) yang melakukan penanganan. Selama BRA dibentuk banyak yang sudah dilakukan , tetapi disisi lain keberadaan badan ini dianggap belum menyelesaikan peran nya secara keseluruhan terhadap tiga komponen yang menerima proses reintegrasi (eks Kombatan GAM, Korban Konflik, dan Tahanan Politik/Narapidana Politik). Tuntutan keberlangsungan proses reintegrasi dengan kembali membentuk suatu badan baru pun di wujudkan dengan membentuk Badan Penguatan Perdamaian Aceh (BP2A). Kehadiran BP2A pada akhirnya mendapat tanggapan yang cukup beragam dari berbagai masyarakat, harapan dengan kembali dibentuk nya badan ini dapat dirasakan manfaatnya oleh masyarakat. Tujuan dari penelitian ini adalah untuk mengetahui apa yang melatarbelakangi Badan reintegrasi Aceh dibentuk kembali dan sejauh mana pengaruh badan reintegrasi Aceh dalam upaya penyelesaian reintegrasi Aceh. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif. Teknik pengumpulan data yang digunakan yaitu penelitian lapangan dan penelitian kepustakaan. Studi lapangan untuk memperoleh data primer yang dilakukan dengan wawancara. Sedangkan penelitian kepustakaan untuk memperoleh data skunder berdasarkan buku-buku dan bacaan terkait. Hasil penelitian ini menjelaskan bahwa evaluasi dari Badan reintegrasi Aceh yang dibentuk belum menyelesaikan peranan nya secara maksimal terhadap tiga komponen. Keberadaan badan ini juga telah menjadi pemicu konflik horizontal di Aceh karena pengelolaan nya yang tidak transparan, akuntabilitas dan profesional. Seharusnya badan ini bisa memberi harapan besar dalam penanganan permasalahan reintegrasi Aceh yang belum selesai dan menutup keterbatasan badan reintegrasi yang sudah lebih awal dibentuk, dengan fokus pada pemberdayaan korban agar bisa mandiri dengan kemampuan individu dan mandiri secara finansial. Kata Kunci : Reintegrasi, Perdamaian, Badan Reintegrasi Aceh, BadanPenguatan Perdamaian Aceh ABSTRACT Aceh reintegration journey began in 2006-2012 throught a temporary agency (ad hoc), know as the Aceh Reintgration Agency (BRA) which make the hadling. During the BRA was established much has been done, but on the other hand the existence of the agency is deemed not yet completed its overall role of the three components that receive reintegration process ( ex-GAM combatants, Innocent Victims in Conflict, and Political Prisoners). Demands sustainability of the reintegration process to re-establish a new institution was embodied by establishing the Agency Strenghening Peace in Aceh (BP2A). Attedance BP2A finally got a response which is quite different from the various communities, the expectation with his re-formed institution can be perceived by society. The purpose of this study was to whether the underlying Aceh reintegration agency was re-established and the extent of influence Aceh reintegration agency in solving the Aceh reintegration. The method used in this research is descriptive qualitative method. Sample collection techniques were used that field research and library research. Field studies to obtain primary sample thought interview. While the library research obtain secondary sample based on the books and related reading. The result of this study explained that the evaluation of the Aceh reintegration agency that set up yet completed its role to the maximum of three components. The existence of this institution also has a trigger horizontal conflicts in Aceh because its management is not transparent, accountability, and professional. Supposedly this body could give great hope in the hadling problems of Aceh reintegration unfinished and perfected limitations reintegration agency had earlier established, with a focus on empowering the victim to be self-sufficient with the ability of individuals and financially independent.

Central Kalimantan is a province in Indonesia located on Kalimantan Island. Most of the province's territory is covered by tropical rainforest. The lowlands are crossed by a swamp belt formed by the Lamandau, Arut, Seruyan, Katingan, Kahayan, Kapuas, and Barito rivers. Because Kalimantan has many river basins, its people also adhere to a way of life that is strongly influenced by nature. The values contained in it are also the values that exist in society. Central Kalimantan also has a lot of folklore because Central Kalimantan is divided into several Dayak tribes, and the unique topology of the region makes each folktale different. This research aims to represent society as presented through folk tales entitled Six Folk Tales of the Central Kalimantan watershed, describing the similarities and differences in values in six folk tales, namely AMDM, TPTP, NBKA, KRPM, BTBI, and DBKBP originating from Barito, Kayahan, and Katingan. This research uses a qualitative descriptive research methodology. This research aims to describe the Comparison of Cultural Values of Folklore in the Central Kalimantan River Basin (Hermeneutics and Intertextual Studies) as a representation of the values of Dayak folklore in the Central Kalimantan River Basin. The Dayak people who live in the Central Kalimantan river basin certainly have unique values compared to other areas of Central Kalimantan. Through a comparison of the six folktales, it can be seen that the cultural values of the Dayak people include, among other things, cultural values related to (1) cultural values between humans, and (2) cultural values with nature. , (3) cultural values with society, and (4) human relationship with God.
