Desa salimbatu termasuk salah satu wilayah yang mempunyai sumber energi alternatif dari limbah lingkungan. Salah satunya adalah pemanfaatan limbah pertanian berupa limbah sekam padi dan serbuk gergaji. Melihat potensi limbah sekam padi dan serbuk gergaji yang dapat diolah lebih lanjut menjadi produk yang lebih memiliki nilai ekonomi seperti briket, sehingga diharapkan dapat meningkatkan perekonomian masyarakat salimbatu. Kegiatan ini dilakukan dalam beberapa tahapan yaitu perencanaan, pelaksanaan dan pelaporan. Tahapan perencanaan yaitu tahap dilaksanakan survei pra kegiatan untuk mengetahui kondisi dan potensi desa salimbatu. Tahap pelaksanaan dilakukan 4 kegiatan yaitu : 1) Dilakukan kegiatan sosialisasi terkait pengolahan limbah sekam padi dan serbuk gergaji; 2) Sosialisasi pengenalan briket; 3) Pelatihan Penggunaan alat pengepres briket; 4) Pelatihan pembuatan briket arang berbahan limbah sekam padi dan serbuk gergaji. Luaran dari kegiatan ini berupa luaran wajib dan luaran tambahan. Luaran wajib berupa manual/panduan aplikasi teknologi produk PHP2D, profil dan poster hasil pelaksanaan program, dokumentasi pelaksanaan berupa video kegiatan, publikasi artikel pada media sosial, sedangkan luaran tambahan berupa publikasi artikel di jurnal nasional ber ISSN terakreditasi, publikasi artikel pada media massa cetak lokal, dan MoU kerjasama anatara mitra dengan tim pelaksana.
The high increase in energy use causes renewable energy solutions such as wind energy, geothermal energy, biomass and others. Biomass is one solution for Indonesia to obtain energy, because Indonesia has the potential for biomass, both biodiesel and bioethanol. The biomass to be studied is Bioethanol. Forest banana is a type of wild plant that grows in the forests of North Kalimantan and is not consumed by residents because there are many seeds in the banana. The purpose of this study was to examine the characteristics of bioethanol from forest bananas. The stages of the research method that will be carried out include several stages, namely 1) making bioethanol, 2) measuring ethanol content, and 3) testing the characteristics of bioethanol. The stages of bioethanol testing carried out characteristic tests including: 1) Ethanol Content Analysis, 2) Moisture Content Analysis, 3) Density Analysis, 4) Specific Gravity and API Gravity Analysis, 5) Calorific Value Analysis. Based on the research results obtained, the quality of the bioethanol produced has a density value and specific gravity in accordance with the bioethanol quality standard, which is 0.46. The calorific value which has a close relationship with API Gravity is close to the maximum value in the bioethanol quality standard, which is 3702.30 kcal/kg. The value of ethanol content and water content still does not meet the quality standards, namely 24.8% and 86%. This is due to the lack of distillation process in this study.
The study aimed at generating PBL-based learning kit product by utilizing blog, at meeting the criteria of learning kit feasibility, at testing the effectiveness of learning kit that the researcher had developed and at identifying the learning participants’ scientific process and problem solving skills. In conducting the study, the researcher implemented the 4-D Model. The learning kit development started involved preliminary study, product design, expert and practitioner test, limited experiment and field experiment. The instruments that had been deployed in conducting the study consisted of validation sheet, learning management observation sheet, student response sheet, teacher interview sheet and learning results test. This study generated a product that consisted of lesson plan, teacher’s book, student’s book, student’s working sheet, blog and learning results assessment. The validation results showed that the learning kit that had been developed were feasible for implementation. Then, the experiment results showed that the learning kit that the researcher had developed met the criteria of effectiveness. Based on the pretest and the posttest results that was administered during the field experiment, students’ physics learning has increased approximately 17.10 point from the pretest average score, namely 58.20, and from the posttest average score, namely 75.30.

: Beauty is the most beautiful gift that God gives to every woman, how to care for it is also a nature that cannot be separated from the discussion of women, especially in the current millennial era. Beauty for the perception of many women can be relative and difficult to describe, but its meaning can be seen in different perspectives. This study aims to reveal what the meaning of beauty looks like for students of the IAIN Metro Social Studies Department, because based on the author's observations it is found that there are differences in perceptions in terms of interpreting beauty which tend to be seen from appearance so that students try to look beautiful by wearing make-up on campus so that beauty becomes a necessity of social recognition, appreciation and self-actualization. This study was analyzed using the theory of Phenomenology by Alfred Schutz. This study uses a qualitative research method with a phenomenological study approach. The results showed that there were various perceptions of the meaning of beauty for each student, especially Tadris IPS IAIN Metro students in interpreting beauty which tended to be objective in terms of: (1) ideal body shape (2) white and bright skin (3) attractive (outer beauty) rather than subjective meaning as seen from (1) Intellectual Intelligence (2) Emotional Intelligence (3) Spiritual Intelligence (Inner Beauty). The meaning of beauty for students is very diverse, every effort is made to meet certain beauty standards because then they will be more confident, get praise and attention and feel welcomed in a social environment.
