Abstract

Fingerprint is a technology that can be used to identify a person. The dusting method is most often used on latent fingerprints because it is relatively easy and simple. However, the composition of the ingredients used in latent fingerprint powder is toxic and can be hazardous to health. This research was carried out using a new natural powder from Suji leaf as a simple, non-toxic, and cheaper. Suji leaf powder produces a green color that comes from the chlorophyll compounds contained in it. This chlorophyll compound will bind to alanine to identify latent fingerprints. The particle sizes used in this study were of 60-200 mesh. The results found that the particle sizes of 100 and 200 mesh provided good green contrast and clear visualization of the fingerprint patterns. Meanwhile, at the particle size of 60 and 80 mesh, it was found that the results were not clear visualized. The highest percentage of fingerprint patterns based on blood group, gender and ethnicity was found in form of loops. The percentage of fingerprint patterns formed based on the highest was of O 31.1; B 12.2; AB 8.8; and A 6.6 percent. The highest percentage of fingerprint patterns formed by gender were of 45.5 for women and 13.3 percent for men. The highest percentage of fingerprint patterns formed by ethnicity were Malay 21.1, Batak 20, and Javanese 17.7 percent.

Abstrak: Masyarakat Desa Banyumas Kec. Stabat Kab. Langkat Sumatera Utara mayoritas berprofesi sebagai peternak lembu dan biasanya mengandalkan rumput sebagai sumber utama pakan ternak lembunya. Namun, ketersediaan rumput pakan semakin sedikit dengan bertambahnya areal pemukiman. Desa Banyumas berbatasan langsung dengan areal perkebunan tebu milik PTPN II Sumatera Utara. Setiap musim panen, dihasilkan limbah pucuk tebu sebanyak 560 ton perharinya. Limbah pucuk tebu ini berpotensi sebagai sumber pakan hijauan pengganti rumput. Namun, masyarakat peternak Desa Banyumas belum memiliki pengetahuan tentang pemanfaatan limbah pucuk tebu sebagai pakan ternak, selain itu masyarakat belum memiliki teknologi tepat guna (TTG) alat pencacah limbah pucuk tebu. Tahapan pelaksanaan kegiatan ini yaitu (1) Pendidikan: sosialisasi pemanfaatan limbah pucuk tebu sebagai pakan ternak, (2) Penyediaan alat TTG pencacah pucuk tebu, dan (3) Pelatihan pembuatan pakan ternak dari limbah pucuk tebu. Limbah pucuk tebu diolah menjadi produk silase melalui proses fermentasi. Sebelum dilakukan fermentasi, pucuk tebu terlebih dahulu dicacah menggunakan TTG alat pencacah pucuk tebu. Pada setiap tahap kegiatan ini, masyarakat peternak sangat antusias dan turut aktif. Pengetahuan masyarakat peternak juga telah meningkat yang semula belum mengenal produk pakan dalam bentuk silase kini mampu membuat silase secara mandiri. Abstract: Banyumas Village society, Stabat Districts, Langkat Regency, North Sumatra Province majority work as cattle breeders and usually rely on grass as the main source of their cattle feed. However, the availability of forage grass decreases with increasing residential area. Banyumas village is directly adjacent to the sugar cane plantation area belonging to PTPN II North Sumatra. Every harvest season, 560 tons of sugarcane shoots are produced per day. This sugarcane shoot waste has the potential as a source of forage substitute for grass. However, the farming community of Banyumas Village does not yet have knowledge about the use of sugarcane shoots waste as animal feed, besides that the community does not yet have appropriate technology for chopping sugarcane shoots waste. The implementation stages of this activity are (1) Education: socialization of the utilization of sugarcane shoots waste as animal feed, (2) Provision of sugarcane shoots chopper TTG equipment, and (3) Training on making animal feed from sugarcane shoots waste. Sugarcane shoot waste is processed into silage products through a fermentation process. Prior to fermentation, the shoots of sugar cane were first chopped using a TTG tool for chopping sugar cane shoots. At each stage of this activity, the farming community is very enthusiastic and actively participates. The knowledge of the farming community has also increased, those who were previously unfamiliar with feed products in the form of silage are now able to make silage independently.

Abstract

This study was aimed at assessing the effectiveness of Project-Based Learning (PjBL)-based analytical chemistry flipbooks in improving students’ critical thinking skills and scientific literacy, and linking the results to the achievement of Sustainable Development Goals (SDG-4), namely quality education. This study used a quantitative approach with a quasi-experimental design, involving two groups: an experimental group (n = 250) using PjBL-based flipbooks, and a control group (n = 250) using conventional textbooks. The projects in PjBL were designed to challenge students to apply critical thinking skills in solving real problems in analytical chemistry. Scientific literacy was measured based on students’ ability to understand, evaluate, and apply chemical concepts in the context of the project. Critical thinking skills and scientific literacy tests were used to measure learning outcomes before and after the intervention. The instrument in this study was a test of critical thinking skills and scientific literacy. Statistical tests showed that the data were normally distributed (significance value 0.216), homogeneous variance (0.074), and significant differences between the experimental and control groups (t = 0.038, p < 0.05). The increase in n-gain in the experimental group reached 0.9 (high category), compared to 0.63 (moderate category) in the control group. This study concluded that Project-Based Learning-based flipbooks were significantly more effective than conventional textbooks in improving students’ critical thinking skills and scientific literacy. The results of this study confirmed the superiority of PjBL-based flipbooks in significantly improving students’ critical thinking skills and scientific literacy compared to conventional textbooks. Statistical data support (normal distribution, homogeneous variance, significant differences between groups, and high n-gain in the experimental group) encourages the adoption of PjBL-based flipbooks as an effective learning strategy to achieve quality education according to SDG-4.

Abstract

Project based learning (PjBL) dianggap sebagai pendekatan yang efektif untuk meningkatkan kemampuan berpikir kritis mahasiswa. Tujuan studi ini adalah untuk meninjau secara sistematis studi-studi empiris tentang implemenyasi project based learning dan bagaimana hal itu mempengaruhi kemampuan mahasiswa dalam berpikir kritis. Metode tinjauan literatur digunakan dalam penelitian ini. Informasi dikumpulkan dari sejumlah basis data akademik, termasuk Google Scholar, Sciencedirect, dan Scopus. Penelitian yang relevan kemudian dianalisis untuk menentukan tren, kesimpulan, dan variabel penting yang mempengaruhi hubungan antara PjBl dan kemampuan berpikir kritis. Hasil ini menunjukkan bahwa peningkatan kemampuan berpikir kritis mahasiswa secara signifikan terkait dengan penerapan PjBL. Penugasan proyek, kerja kelompok, dan refleksi diri semuanya membantu dalam hal ini. Namun, suasana belajar kolaboratif, dukungan dosen dalam memfasilitasi, dan desain proyek yang terorganisir dengan baik semuanya sangat penting untuk efektivitasnya. Sehingga perlu dilakukan penelitian lanjutan untuk menilai efektifitas penerapan project based learning di perguruan tinggi dalam meningkatkan kemampuan berpikir kritis mahasiswa
