The gasification process was occured in reactor for one hour, and syn gas which produced has been analized to know the composition of it. Result shows that raw material have influenced the characteristic of gasification process. The highest heating rate was occured for gasification process of 100% leaf and AFR 0.5, which it gas has burned after 25 minuted process in oxidation temperature of 650 0C, reduction temperature of 350 0C, and pyrolysis temperature of 240 0C
Skenario Pengembangan Sumur Injeksi pada Sumber Daya Panas Bumi Sistem Dominasi Air dengan Pemodelan Reservoir 3D Dinamik
Get PDFReinjeksi fluida memiliki peran penting dalam pengelolaan reservoir panas bumi. Reinjeksi bertujuan untuk meningkatkan pengisian alami ke reservoir untuk menjaga tekanan reservoir, produksi uap, dan mengekstraksi lebih banyak panas dari reservoir. Penginjeksian kembali harus direncanakan dengan baik untuk menghindari masalah seperti terobosan termal. Pemodelan dinamis reservoir panas bumi dapat digunakan untuk mengidentifikasi kondisi awal reservoir, karakteristik produksi, dan kinerja produksi reservoir di masa depan. Dalam studi ini, reinjeksi ke reservoir yang didominasi air sintetis direncanakan untuk mempertahankan 55 MW produksi listrik selama 30 tahun. Tujuan dari penelitian ini adalah untuk menentukan strategi injeksi terbaik untuk mencapai produksi listrik selama 30 tahun. Berbagai skenario produksi-injeksi diuji menggunakan pemodelan reservoir panas bumi 3D dinamis. Studi ini menunjukkan bahwa lokasi dan laju injeksi adalah parameter utama dalam strategi injeksi. Sumur reinjeksi terletak di dalam reservoir, tetapi pada jarak yang cukup untuk menghindari terobosan. Suntikan area dekat produksi menyebabkan terobosan dalam sumur produksi. Injeksi pada tingkat yang lebih tinggi memperlambat penurunan tekanan dan meningkatkan produksi cairan secara signifikan.Reinjection aims to increase the natural recharge to reservoirs in order to maintain the reservoir pressure, steam production, and extract more heat from the reservoir. Reinjection must be well planned to avoid problems such as thermal breakthrough. Dynamic modelling of geothermal reservoirs can be used to identify the future production performance of the reservoir. In this study, reinjection to a synthetic water-dominated reservoir is planned to maintain 55 MW of electricity production for 30 years. The purpose of this study is to determine the best injection strategy. Various production-injection scenarios are tested. The study shows that location and injection rate are the key parameters in injection strategy. The production well are located inside the reservoir, but enough distance to avoid a breakthrough. Near-production area injections are causing breakthrough in production well. Injection at higher rates slows down pressure decline and increase the fluid production significantly

Kemiskinan dan Ekonomi Kesejahteraan
Get PDFIsu kemiskinan seakan tidak pernah habis selama masih banyak warga yang hidup di bawah garis kehidupan yang layak. Kemiskinan perlu diatasi dengan program-program pembangunan ekonomi yang benar-benar mensejahterakan, namun sayangnya hal itu masih sebatas program yang terkesan muluk-muluk, namun belum memberi dampak yang signifikan.Artikel ini akan mengkaji kemiskinan yang dikaitkan dengan konsep ekonomi kesejahteraan, dengan fokus pada pemikiran peraih Nobel 1998 yang merupakan profesor ekonomi kelahiran India, Amartya Sen. Pemikiran-pemikirannya banyak memberikan dasar penting bagi pembangunan ekonomi yang berkeadilan.Ekonomi kesejahteraan perlu ditopang dengan semakin kuatnya peran negara. Hal ini dilakukan untuk mengatasi gerak ekonomi kapitalisme yang semakin menghantui kehidupan masyarakat di era modern saat ini. Diharapkan dengan ekonomi kesejahteraan, kemiskinan bisa diatasi dan kehidupan masyarakat menjadi semakin lebih baik. Kata kunci: kemiskinan, ekonomi kesejahteraan, Amartya Sen
Hubungan Antara Efikasi Diri dengan Motivasi Berprestasi Pada Mahasiswa Universitas X Yogyakarta
Get PDFObjective of this research was to understand the relationship between self- efficacy (independent variable) and achievement motivation (dependent variable) among university students. There were 60 students participated in this study, aged 18-21 years old, and full-time students. Two instruments were created in this study i.e. the self-efficacy scale and achievement motivation scale. The data collection was analyzed through the product moment correlation technique. This research revealed that there was a positive and significant correlation between the students’ self-efficacy and their achievement motivation (r = .683. p<.01). The self-efficacy variable was able to predict 46.6% of the achievement motivation. The rest was undetected under this research. Probably, the students’ employment situation should be considered, in spite of their status as the full-time students. Employment situation at this time is not only working at an organization, but also becoming an entrepreneur. At this time, it is very common among university students to be a startup entrepreneur. This working situation surely influences their achievement motivation. Key words: Self-efficacy, Achievement Motivation, University Student.
PUTUSAN HAKIM SARPIN, BERKAH YANG TERSEMBUNYI BAGI PERLINDUNGAN HAK ASASI MANUSIA
Get PDFTujuan dari tulisan ini adalah untuk menganalisis putusan Hakim Sarpin, salah satunya yaitu melalui Putusan Mahkamah Konstitusi Nomor 21/PUU-XII/2014. Ada beberapa yang menganggap bahwa putusan ini sebagai wujud penghormatan HAM, namun ada juga yang beranggapan bahwa putusan ini adalah bentuk pengkhiantan terhadap semangat pemberantasan korupsi di Indonesia. TAP MPR-RI No.XVII/MPR/1998 tentang HAM, menyatakan Pembukaan UUD Tahun 1945 telah mengamanatkan pengakuan, penghormatan, dan kehendak bagi pelaksanaan HAM dalam menyelenggarakan kehidupan bermasyarakat, berbangsa dan bernegara. Bangsa Indonesia sebagai bagian masyarakat internasional patut menghormati hak asasi manusia yang termaktub dalam Universal Declaration of Human Rights serta instrumen internasional lainnya mengenai hak asasimanusia. Putusan Mahkamah Konstitusi Nomor Nomor 21/PUU-XII/2014 adalah salah satu wujud dihormatinya HAM di Indonesia. MK dalam pertimbangan-pertimbangan dikeluarkannya Putusan MK Praperadilan juga kerap menggunakan penghormatan dan perlindungan HAM. Terlebih lagi, MK menganggap penetapan tersangka adalah bagian dar iupaya paksa yang dilakukan oleh aparat penegak hukum.Oleh karena itu MK memandang perlu diadakannya pengawasan terhadap penetapan tersangka, yaitu melalui praperadilan.Kata Kunci : Putusan Hakim Sarpin dan Perlindungan Hak Asasi Manusia
RELATIVISME BUDAYA DALAM HAK ASASI MANUSIA
Get PDF Tujuan tulisan ini adalah untuk mendeskripsikan bagaimana relativisme budaya berpengaruh terhadap hak asasi manusia. Pertentangan antara teori universalisme dan teori relativisme budaya dalam memandang Hak Asasi Manusia, sejatinya sudah dimulai sejak munculnya pemikiran atas hak-hak kodrati manusia. Sebagian pemikir memandang bahwa manusia memiliki hak yang muncul secara alamiah tanpa adanya peran ataupun campur tangan dari pihak lain. Sedangkan sebagian lain menganggap bahwa hak-hak manusia berasal dari hukum, hak tidak akan pernah ada tanpa hukum yang mengatur. Teori relativisme budaya memandang Hak Asasi Manusia berbedabeda, terbatas pada wilayah tempat tinggal dan kebudayaan. Apa yang menjadi hak bagi satu kelompok masyarakat belum tentu menjadi hak bagi kelompok masyarakat yang lain. Didahulukannya kepentingan masyarakat ini menjadikan keputusan Mahkamah Konstitusi yang menolak uji materi terhadap hukuman mati, wajar dan pantas dilakukan. Karena keputusan itu diambil guna mewujudkan ‘sesuatu yang lebih besar’. Dalam hidup bermasyarakat (terutama di negara-negara yang masyarakatnya bersifat komunal), tentu ada kewajiban-kewajiban sosial yang harus dilakukan. Kewajiban ini harus dilakukan terlebih dahulu sebelum seseorang dapat menuntut haknya. Bahkan lebih jauh, masyarakat lah yang menentukan apa yang menjadi hak seseorang, karena hak hanya ada di dalam masyarakat. Kewajibankewajiban ini tentu tidak muncul pada Teori Hak Kodrati, karena Hak Asasi Manusia secara natural telah dimiliki oleh setiap manusia. Ini tentu tidak dapat diterapkan di masyarakat yang komunal. Inilah yang disebut relativisme budaya. Kata Kunci : Relativisme budaya, hak asasi manusi
