Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi limbah kepala udang dan daun singkong terhadap pertumbuhan dan kandungan protein maggot Black Soldier Fly (BSF). Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan: P1 (100% kepala udang), P2 (75% kepala udang + 25% daun singkong), P3 (50%+50%), P4 (25% kepala udang + 75% daun singkong), dan P5 (100% daun singkong). Masing-masing perlakuan dengan tiga ulangan. Variabel yang diamati meliputi berat, panjang, ketebalan maggot, konsumsi pakan, laju pertumbuhan spesifik (SGR), indeks pengurangan limbah (WRI), serta kadar protein. Hasil penelitian menunjukkan bahwa secara deskriptif, nilai rata-rata berat maggot berkisar antara 0,04-0,055 g, panjang antara 10,80-11,73 mm, dan laju pertumbuhan spesifik (SGR) antara 6,13-7,23%. Kadar protein maggot tercatat antara 25,09-27,32%, konsumsi pakan berkisar antara 86-93%, dan efisiensi reduksi limbah (WRI) berada pada rentang 5,28-6,64 g/hari. Berdasarkan hasil analisis ragam, seluruh variabel yang diamati tidak menunjukkan perbedaan yang signifikan antar perlakuan (p > 0,05). Dengan demikian, meskipun terdapat variasi nilai secara deskriptif, perbedaan tersebut tidak dapat dianggap nyata secara statistik dan tidak mencerminkan pengaruh perlakuan yang berbeda terhadap pertumbuhan maggot BSF. Penelitian lanjutan perlu dilakukan dengan jumlah sampel yang lebih besar, serta analisis kandungan nutrisi pakan yang lebih rinci, guna memperoleh hasil yang lebih akurat dan aplikatif. ABSTRACT This study aims to investigate the effect of combining shrimp head waste and cassava leaves on the growth and protein content of Black Soldier Fly (BSF) maggots. The study used a Completely Randomized Design (CRD) with five treatments: P1 (100% shrimp heads), P2 (75% shrimp heads + 25% cassava leaves), P3 (50% + 50%), P4 (25% shrimp heads + 75% cassava leaves), and P5 (100% cassava leaves). Each treatment had three replications. The observed variables included weight, length, thickness of maggots, feed consumption, specific growth rate (SGR), waste reduction index (WRI), and protein content. The results of the study showed that descriptively, the average maggot weight ranged from 0.04-0.055 g, length between 10.80-11.73 mm, and specific growth rate (SGR) between 6.13-7.23%. Maggot protein content was recorded between 25.09-27.32%, feed consumption ranged from 86-93%, and waste reduction efficiency (WRI) was in the range of 5.28-6.64 g/day. Based on the results of the analysis of variance, all observed variables did not show significant differences between treatments (p > 0.05). Thus, although there were variations in descriptive values, these differences cannot be considered statistically significant and do not reflect the effect of different treatments on the growth of BSF maggots. Further research is needed with a larger sample size, as well as a more detailed analysis of feed nutrient content, to obtain more accurate and applicable results.

Abstract

Organic wastes of tilapia offal, coconut pulp, and plantain are rarely optimally utilized, but they can be degraded by BSF larvae into nutritious biomass. This study aims to analyze the combination of organic waste macronutrient feed on bioconversion, survival, growth (weight, length, and thickness), and nutritional value (protein, fat, and carbohydrates) of BSF prepupae, using the Completely Randomized Design (CRD) method, 4 treatments P1 (50% tilapia offal: 25% plantain: 25% coconut pulp), P2 (25% tilapia offal: 50% plantain: 25% coconut pulp), P3 (25% tilapia offal: 25% plantain: 50% coconut pulp), P4 (33.3% tilapia offal: 33.3% plantain: 33.3% coconut pulp) and 3 repetitions. All treatments resulted in optimal survival (100%, survival). P4 produced an ECD value of 0.034% and WRI of 0.032% indicating the best efficiency and waste reduction. P1 was the best variation for weight at 5.69 g, length 19.7 mm, and thickness 5.8 mm. The Post Hoc Tuckey test showed no significant difference between treatments in weight and thickness parameters, but not in length parameters (<0.05). The protein content of P1 43.75%, fat P2 29.764%, and carbohydrate P2 1.374% were close to SNI 7994:2014 (meat bone meal, quality II). It was concluded that macronutrient feed waste affects bioconversion, survival, growth and nutritional value of BSF.

Abstract

Knowledge continues to evolve, requiring teachers to innovate, particularly in implementing the Kurikulum Merdeka (Independent Curriculum). Field observations indicate that many schools still struggle with its implementation, as they must tailor learning to students' individual characteristics. SMPN 03 Lebong in Bengkulu Province is one such school facing these challenges. Given these issues, an alternative solution is needed to support the independent implementation of the Kurikulum Merdeka. One possible approach is to provide training for teachers at SMPN 03 Lebong on designing learning activities and practical worksheets based on the Prediction, Observation, and Explanation (POE) model. This training follows the I-CARE design, which consists of five stages: Introduction, Connection, Application, Reflection, and Extension. As a result, teachers successfully developed six learning designs and practical guides based on the POE model, utilizing available tools and materials from their surroundings. This initiative enhances student-centered learning, aligning with the objectives of the Kurikulum Merdeka.

Abstract

The detection of borax in food is of critical importance due to its toxic properties, which pose serious health risks, especially when consumed continuously, even in small amounts. Therefore, an environmentally friendly, accessible, and easy-to-use detection method is needed for broader application, particularly in routine food monitoring. This study introduces a novel quantitative detection approach using butterfly pea flower (Clitoria ternatea L.) extract as a natural indicator, combining visual colorimetry and UV-Vis spectrophotometry for dual-mode borax analysis. Unlike previous studies that focused solely on qualitative color observation, this research establishes a quantitative correlation between absorbance and borax concentration, supported by strong linearity (R² = 0.9942) and high sensitivity (LoD = 0.026 ppm; LoQ = 0.088 ppm). The butterfly pea extract, rich in anthocyanins, produced a distinct blue color that shifted to green upon interaction with borax, forming a specific butterfly pea–borax complex with a maximum wavelength (λmax) at 624 nm. Application to real meatball samples revealed borax contents of 0.528% and 0.4641% in two samples, respectively. The integration of butterfly pea extract with turmeric paper as a dual-confirmation system enhances analytical reliability while maintaining cost-effectiveness and environmental safety. This work contributes a validated, eco-friendly, and quantitative natural detection method that bridges the gap between laboratory precision and community-based food safety monitoring.

Abstract

The forest softshell turtle (Dogania subplana) is a species increasingly threatened by habitat destruction and overexploitation. This study aims to identify the acclimatization process of D. subplana in an artificial environment, specifically, an aquarium at the Turtle Learning Center (TLC). The research was conducted over 30 days from July to August 2024. Observations were made on daily behavior, body temperature, and health condition, individual biometric measurements, and environmental (abiotic) parameters. The results showed that daily behaviors such as feeding, basking, and hiding occurred regularly, indicating the species' ability to adapt to a new environment. The turtles experienced an increase in body weight, while growth in carapace length and width was very slow. The body temperature of D. subplana varied in accordance with the surrounding environmental temperature, reflecting its dependence on ambient conditions. Some individuals experienced minor health issues, such as fungal infections, but the majority remained active and healthy. Environmental factors such as temperature, humidity, pH, dissolved oxygen, total dissolved solids, and light intensity were within ranges conducive to acclimatization. These findings suggest that the aquarium at the TLC is quite effective as an ex situ conservation facility in supporting the adaptation process of D. subplana  outside its natural habitat.

Abstract

Fish have the potential to be contaminated with heavy metals such as lead, which can originate from human activities, industry, and ports. The Bengkulu people have a traditional processing method that is believed to reduce heavy metal content in fish through the immersion of fish in Pendap dishes using water and lemon. This study aims to observe the reduction of heavy metal content in fish during the immersion process using water and lemon juice in Pendap dishes. The research was experimental with positive and negative results and analyzed using the SPSS ANOVA test to see significant differences between treatment groups. The fish used as samples included Tongkol Sarda orentalis, Kembung Rastrelliger kanagurta, Tuna Thunnus albacares, and Tenggiri Scomberomorus Lacepède. The parts of the fish that were analyzed included the muscles, liver, and gills. All samples were exposed to Pb(NO3)2 and divided into 3 treatment groups: 1 positive control, 2 precipitated with water, and 3 precipitated with lemon juice (Citrus limon). The samples were tested using the reagents NaOH, KI, NH4OH, and HCl. Based on the research results, it was found that the application of lemon juice produced significant results in reducing Pb levels, as indicated by the negative test results.
