Abstract

Increasing consumption of fossil fuels and decreasing oil production in Indonesia are the current energy problems. In order to overcome the threat of an energy crisis and optimize the potential of energy resources in Indonesia, research on renewable alternative energy is needed. One of the renewable energy sources is bio-oil. Bio-oil can be produced through the pyrolysis process of palm shell biomass using a ZSM-5 catalyst. In this study, the pyrolysis process was modified by adding hydrogen (hydrogenation pyrolysis), to produce bio-oil which has a higher calorific value. This study aims to determine the effect of pyrolysis temperature and ZSM-5 catalyst ratio on the yield of bio-oil in pyrolysis hydrogenation and to determine the physical and chemical characteristics of the resulting bio-oil. The pyrolysis hydrogenation process uses 50 grams of palm shells measuring -40+60 mesh, 500 ml silinap and a stirring speed of 300 rpm. The highest yield was obtained at a pyrolysis temperature of 320 oC and 2.5% ZSM-5 catalyst with a yield of 70.21%. The results of the physical characterization of bio-oil showed a heating value of 44.00 MJ/kg, a density of 0.972 g/ml, a viscosity of 1.021 cSt, a flash point of 49 oC, a pH of 3.8 and an acidity value of 51.51 g NaOH/g bio-oil. GC-MS analysis showed that the main ingredients of bio-oil were 50.29% acetic acid, 30.39% phenol, 8.19% methyl ester and 5.25% ethanol. The bio-oil obtained can be further processed to become an alternative energy source to replace petroleum.

Abstract

Snakehead fish (Channa striata) is a type of freshwater fish that contains high levels of protein albumin. The research was conducted to determine the albumin content in snakehead fish after the cooking process, both steamed and wrapped. The research was conducted using a completely randomized design with a factorial pattern, the first factor was the cooking method (steamed and wrapped) and the second was cooking time (10, 15, 20, and 20 minutes). Determination of protein albumin levels in snakehead fish after processing using the Biuret method. The steaming process for 15 minutes resulted in protein content in the snakehead fish of 0.76%, while the protein albumin that was lost was 19.28%. The wrapped method for 20 minutes has a remaining protein content of 0.59%, while the missing protein is 38.78%. The method of processing snakehead fish by steaming is better than the wrapping process.

Abstract

This study aims to determine the value theory of character education and structural theory. In line with the research objectives, this research uses qualitative research using descriptive methods. The data used in this study is a combination of intrinsic and extrinsic elements of literary works which include structural theory and the values of character education contained in the novel. The data source used in this research is the novel "One Academic Year" by Junior Dany Wibisono. The results of the analysis of the One Academic Year novel include structural theories such as intrinsic elements consisting of: (1) theme, namely the intrinsic elements of the novel which are the basis of the story, (2) plot/plot which is the storyline, (3) setting which refers to the background. time, atmosphere, and place of the story, (4) characterization is the determination of the character or character of the character, (5) point of view, namely the direction of a writer's point of view in conveying a story, (6) mandate, which is a moral message written by the author of the story. In addition, there are also extrinsic elements. The extrinsic element is the opposite of the novel's intrinsic element. The extrinsic elements of the novel are elements that are outside the literary work, but indirectly affect the structure of the literary work. The extrinsic element of a literary work depends on the author telling the work. Extrinsic elements for example are the values contained, background, and social situation. After structural theory, there are also character education values contained in the novel.

Abstract

Mohammad Hatta hidup dan berkembang pendidikannya mulai dari lingkungan keluarga yang religius hingga lingkungan pendidikan yang mendunia. Pendidikan tinggi diperoleh dari jurusan ekonomi kenegaraan Sekolah Tinggi Ekonomi di Rotterdam, Belanda. Proses pendidikan di Belanda berimbas dalam perannya pada pemikiran teori ekonomi merkantilisme, liberalisme, dan marxisme di Indonesia. Untuk itu tujuan penelitian untuk mengetahui peran pemikiran dan gerakan keilmuan Mohammad Hatta. Penelitian menggunakan metode library research yaitu metode penelitian berbasis kritis yang bersandar pada analisa dan sintesa terhadap data kepustakaan. Langkah penelitian yaitu mencari, memilah, dan menemukan kesenjangan. Data dikumpulkan menggunakan alat bantu bibliographi berupa artikel jurnal dan informasi web. Hasil penelitian menunjukkan bahwa ekonomi kerakyatan yang dibangun oleh Mohammad Hatta berlandaskan teori Merkantilisme yang berbasis penguasa kerajaan tradisional. Teori Marxisme digunakan sebagai alat penggerak teori Merkantilisme sehingga berbaur dengan kepentingan rakyat. Teori Liberalisme digunakan sebagai keperpihakan negara kepada rakyat untuk bekerja sesuai dengan kemampuan masing-masing. Akhirnya, praktik ekonomi kerakyatan. merupakan pilihan /gaya menengahi ketiga teori besar tersebut. Bentuk implementasi ekonomi kerakyatan yaitu koperasi. Rakyat bisa bekerja sama melalui koperasi atas asas kekeluargaan untuk mencapai kesejahteraan sosial. Ekonomi kerakyatan menjadi ekonomi Pancasila dengan adanya Pasal 33 Undang-Undang Dasar Negara Kesatuan Republik Indonesia tahun 1945.

Abstract

Artikel ini membahas tentang relevansi karya sastra, khususnya cerita rakyat, dalam mencerminkan dan menyampaikan berbagai aspek kehidupan manusia serta nilai-nilai budaya. Melalui studi kasus cerita rakyat "Malin Kundang" dari Sumatera Barat, Indonesia, penelitian ini menggunakan pendekatan kualitatif deskriptif analitis. Hasil penelitian menunjukkan bahwa cerita ini tidak hanya menghibur, tetapi juga mengandung pesan moral yang mendalam, seperti pentingnya menghormati orang tua, menjaga kesederhanaan, dan menghargai keragaman budaya. Nilai-nilai ini konsisten dengan nilainilai Pancasila yang mencakup beriman, bertakwa, gotong royong, mandiri, berpikir kritis, dan kreatif. Studi ini menekankan pentingnya menerapkan nilai-nilai tersebut dalam kehidupan sehari-hari untuk membentuk karakter yang kuat dan berintegritas.
