Robotika dalam aspek kehidupan manusia dewasa ini sangatlah penting. Tidak terkecuali pada bidang milter. Saat ini banyak negara berlomba-lomba menunjukkan kemuktahiran robot ciptaannya dalam bidang militer. Indonesia merupakan negara dengan prajurit tempur yang cukup disegani di tingkat Asia, sebut saja Kopasus (Komando Pasukan Khusus). Satuan prajurit Tentara Nasional Indonesia (TNI) ini sangat handal di dalam pertahanan darat Indonesia. Namun hal ini tidak cukup, saat ini banyak negara-negara melibatkan robot sebagai sarana bantu para prajuritnya. Hal ini lah yang mendorong peneliti untuk ikut mengambil peran dalam membantu para prajurit Indonesia nantinya dalam hal surveillance atau pengamatan dengan bantuan sebuah robot. Peneliti merancang dan mebuat sebuah prototype atau purwarupa robot mainland surveillance yang akan digunakan pada prajurit tentara darat. Tahap awal perancangan mekanisme gerak robot merupakan menjadi titik konsern peneliti. Dengan menggunakan roda platform mecanum wheel, robot mainland surveillance diharapkan memeliki navigasi yang memungkinkan dapat bergerak kesegalah arah.

Batik besurek merupakan warisan budaya khas Bengkulu yang dalam praktiknya pewarnaannya masih banyak menggunakan zat pewarna sintetis, yang berpotensi menimbulkan dampak negatif terhadap kesehatan dan lingkungan. Penelitian ini bertujuan untuk mengidentifikasi potensi tumbuhan lokal sebagai pewarna alami dalam pembuatan batik besurek, serta mengevaluasi kualitas dan ketahanan warnanya berdasarkan standar SNI ISO-105. Penelitian dilakukan dengan pendekatan eksploratif untuk mengidentifikasi tumbuhan lokal berpigmen alami, serta pendekatan eksperimental untuk menguji ketahanan warna hasil pewarnaan terhadap pencucian (ISO 105-C06), penjemuran (ISO 105-B02), dan gesekan (ISO 105-X12). Ekstraksi dilakukan menggunakan teknik maserasi dan boiling treatment, serta diaplikasikan pada kain mori menggunakan 3 jenis mordan yaitu tawas, tunjung, dan kapur sirih. Empat tanaman yang digunakan dalam penelitian ini, yaitu Hibiscus rosa-sinensis, Archidendron pauciflorum, Bougainvillea sp., dan Curcuma longa yang dikenal mengandung pigmen alami. Hasil menunjukkan bahwa Curcuma longa memiliki ketahanan warna tertinggi, dengan kategori “tidak pudar” untuk semua parameter ISO-105. Sebaliknya, Bougainvillea sp. menunjukkan ketahanan warna terendah, hanya mencapai skor 1-4 pada beberapa uji. Hasil ini menunjukkan bahwa penggunaan pewarna alami berbasis tumbuhan lokal memiliki potensi besar sebagai alternatif ramah lingkungan dalam pembuatan batik besurek. Pendekatan ini mendukung pelestarian lingkungan, pemanfaatan biodiversitas lokal, serta dapat diterapkan dalam pembelajaran kontekstual di sekolah.

This study aims to improve students’ environmental literacy by developing MEDIPIA, an interactive science learning media based on Virtual Reality (VR). The focus of the research is on water pollution at Teluk Sepang Beach, a coastal area affected by thermal waste discharge from the Teluk Sepang Power Plant. The study follows the 4D development model, which consists of Define, Design, Develop, and Disseminate stages, integrating both media development and environmental analysis. A field trial involving 30 seventh-grade students from SMPN 52 Bengkulu Utara was conducted using a one-group pretest-posttest design to assess changes in students’ environmental literacy. At the same time, seawater quality was analyzed at seven observation points using five parameters: temperature, pH, salinity, dissolved oxygen, and turbidity, based on standards from the Ministry of Environment Decree No. 51 of 2004. The findings indicate ecological disturbance near the wastewater discharge outlet, characterized by temperatures above 30°C, decreased pH at two points, salinity levels below 33‰, turbidity exceeding 5 NTU at four points, and dissolved oxygen above 5 mg/L. Expert validation rated MEDIPIA as highly suitable for educational use, with an average score of 91.79%. Statistically, student environmental literacy increased significantly after using MEDIPIA, with an N-gain score of 0.7 and a p-value of 0.001 (p < 0.05). These results suggest that VR-based interactive media can bridge scientific environmental data and student learning, contributing to the development of context-based science education that addresses local environmental issues

This study aims to develop an ethnoscience-based guidebook by integrating lemea fermentation as a local context in biotechnology learning to improve junior high school students' science process skills. The development model used is ADDIE with a quasi-experimental design of non-equivalent control groups. The research subjects consisted of 48 ninth-grade students from SMPN 02 Lebong, divided into experimental and control groups. Research instruments included observation, expert validation, pretest, posttest, and questionnaires. Validation results indicated product feasibility of 92% (very feasible category). Effectiveness testing using an independent t-test showed a significant difference between the experimental and control groups (Sig. 0.000 < 0.05), with an average N-Gain of 0.43 (moderate) in the experimental group and 0.17 (low) in the control group. The effect of media use on science process skills was moderate. Student and teacher responses to the media were very positive, particularly in terms of appearance, content, and usefulness. These results indicate that the integration of local culture into science is effective in developing students' scientific skills in a contextual manner.

Background: Fruit juice is highly needed nowadays due to its effectiveness as a source rich in antioxidants.Research Objective: This study aims to reduce glucose levels caused by the administration of HgCl₂, which is neurotoxic and cytotoxic, capable of damaging pancreatic β-cells that produce insulin. Etlingera hemisphaerica was utilized as a potential solution because it contains compounds such as terpenoids, flavonoids, phenols, and polyphenols that can lower glucose levels by maintaining the normal function of pancreatic β-cells. Method: This study applied a true experimental method with a pretest-posttest control group design, involving measurements taken before and after treatment. The subjects were divided into three test groups K1, K2, and K3 each consisting of three Mus musculus , with a total of nine mice. Results: The administration of Etlingera hemisphaerica Fruit Fresh Drink (MSBE) did not show a significant effect in reducing blood glucose levels in Mus musculus induced with HgCl₂. Conclusion: The secondary metabolites contained in E. hemisphaerica have not yet been able to repair or maintain blood glucose levels under conditions of damage caused by HgCl₂ exposure.
