Abstract

“Kolang kaling” is the endosperm of Arenga pinnata seed that contains galactomannan so it can be made into jam. This research was aimed to study the effect of “Pucuk merah” fruit juice as a natural colorant and antioxidant sources on antioxidant activity of the jam. This research used an experimental design with different levels of the juice of “Pucuk merah” fruit (6%, 8%, 10%, and 12%). Observations were anthocyanin level (pH differential method), total phenol (by Follin-Ciocalteu method) and antioxidant activity (by DPPH method) of the jam. It was found that the addition of the concentration level of “Pucuk merah” fruit juice had a statistically significant effect on the anthocyanin and total phenol level of the jam. The more the juice was added, the higher the anthocyanin level (2.82 ± 0.13 ppm; 3.76 ± 0.29 ppm; 3.88 ± 0.11 ppm; and 4.20 ± 0.52 ppm, respectively) and the higher the total phenol level (382 ± 1.53 mg GAE/100g; 431 ± 3.06 mg GAE/100g; 540 ± 1.53 mg GAE/100g and 547 ± 6.43 mg GAE/100g, respectively). By using sensory evaluation, the best product was the addition of 12% of the juice; the antioxidant activity was 628 ppm.

Abstract

In 2016 amounted to 34,599 tons while the safety stock according to the min-max stock method was 5,853 tons. In 2017 the final inventory of clay raw materials was 45,694 tons while the safety stock according to the min-max stock method was 3,438 tons. In these two years, it shows that the amount of inventory of final inventory of clay raw materials is very large when compared to inventory according to the method of min- max stock. End supplies of woven paper raw materials. the final inventory of raw material for woven paper is greater than the inventory according to the min-max stock method of 2,441,774 meters while the safety stock according to the min-max stock method is 982,732 meters The final inventory of BCO raw materials in 2016 was 180,140 liters while the safety stock according to the min-max stock method was 20,534 liters. In 2017 the final inventory of BCO raw materials at PT. Semen Tonasa is 202,367 liters while the safety stock according to the min-max stock method is 10,432 liters. In these two years, it shows that the amount of inventory of final inventory of BCO raw materials is very large when compared to inventories according to the Min-max stock method

Abstract

This Wireless Analog to Digital Data Logger research aims to design a prototype measuring tool that is useful for converting analog data into digital data, or an Analog to Digital Converter (ADC), without using cable media (wireless), where the communication media used in this research is Bluetooth by using the HC-05 module and Arduino Uno as the main control system. The system output of the measurement results in this research is displayed on the Android phone in the form of decimal numbers to make it easier to read, along with the date, month, and year, as well as the time when the measurement was taken. This system is also equipped with a graphic display of measurement results in real time, making it easier for users to monitor changes in data that occur visually. This measuring tool also has a facility for storing measurement data in the form of an Excel file with CSV (comma separated values) format, which can be downloaded from the data storage media on the Android phone used, making it easier for users to process or retrace the measurement data on other media such as computers.

Abstract

Kemampuan literasi dan numerasi merupakan fondasi utama pembelajaran abad ke-21 yang menentukan kualitas sumber daya manusia di masa depan. Namun, hasil PISA 2022 (OECD, 2023) menunjukkan bahwa capaian literasi dan numerasi siswa Indonesia masih berada di bawah rata-rata negara OECD. Kondisi ini lebih nyata di wilayah pedesaan seperti Kabupaten OKU Timur, di mana keterbatasan sumber belajar, minimnya inovasi pembelajaran, serta kurangnya pendekatan kontekstual menyebabkan rendahnya minat anak dalam membaca dan berhitung. Kearifan lokal, yang mencakup permainan tradisional, simbol budaya, dan cerita rakyat, memiliki potensi besar sebagai sarana edukatif untuk memperkuat kemampuan literasi dan numerasi sekaligus menumbuhkan kesadaran budaya. Berdasarkan pemikiran tersebut, kegiatan pengabdian kepada masyarakat ini dirancang untuk mengintegrasikan unsur budaya lokal Desa Nirwana ke dalam aktivitas pembelajaran literasi dan numerasi. Pendekatan yang digunakan bersifat partisipatif dan kontekstual melalui kegiatan membaca, menulis, berhitung, serta permainan edukatif berbasis budaya lokal. Tujuan utama kegiatan ini adalah meningkatkan kemampuan dasar anak sekaligus menghidupkan kembali nilai-nilai budaya masyarakat setempat. Dengan mengaitkan pembelajaran pada konteks kehidupan sehari-hari dan warisan budaya lokal, kegiatan ini diharapkan mampu meningkatkan motivasi belajar, memperkuat keterampilan berpikir kritis, serta memperluas pemahaman anak terhadap makna literasi dan numerasi dalam kehidupan nyata.

Abstract

The lack of understanding and interest among students in learning science and the scarcity of energy are very interesting topics to study using case-based learning. The novelty lies in the use of Case Based Learning and Artificial Intelligence related to renewable energy. The objectives of the study are (1) to identify the Hypothetical Learning Trajectory (HLT) of renewable energy based on learning barriers, and (2) to measure scientific process skills and digital literacy. The sample consisted of 120 high school students in Lubuklinggau. The research design was a Lesson Study approach. Implementation occurred over two cycles in collaboration with teachers to design renewable energy learning materials, including lesson plans (RPP), Student Worksheets (LKPD) 1 and 2. AI tools used included Padlet, Kahoot, and Cap Cut. Data collection involved documentation, observation, and interviews. Data analysis was conducted using quantitative descriptive methods. Learning difficulties were identified in students' inability to conduct investigations, analyze data, and communicate graphs effectively. LKPD 1 and 2 were found to be highly valid with a validity test score of 0.92, making them suitable for use. Additionally, there was an increase in students' average science process skills by 0.87, categorized as high, and digital literacy by 0.88, categorized as highly skilled. Its contribution lies in integrating digital LKPD that is easy to access and engaging due to AI integration. Furthermore, the LKDP developed involves students conducting experiments and field observations to measure the efficiency of biomass stoves fueled by rice husks, wood chips, and LPG stoves. Another interesting finding is that students with low abilities experienced a very high increase in digital literacy. The next step is to develop diagnostic test instruments for science literacy, digital literacy, and learning modalities.
