Abstract

This research aims to describe the ability of mealworms (Tenebrio molitor) to reduce styrofoam waste by observing the decrease in styrofoam weight and survival rate over one week. The method used is an experiment with a Completely Randomized Design (CRD) with 4 treatments (P0, P50, P100, P150) and 4 replications. The data was analyzed using descriptive statistics. The research stages include container preparation, larvae, stocking, feeding, and maintenance. The results show that the weight loss of styrofoam occurred at P50 (18.5%), P100 (22.75%), and P150 (36%). Meanwhile, the control group (P0) only experienced a weight loss of 1.5%. This indicates that the greater the number of T. molitor, the greater the weight loss of styrofoam. The highest survival rate for T. molitor was observed at P50, with a decrease in numbers of only 12.5%. At P150, the decrease was 16.8%, and at P100, it was 28.75%. This decrease is suspected to be caused by competition among T. molitor, population density, and a lack of nutrients despite the addition of supplementary feed. Based on the analysis of the results, it can be concluded that T. molitor is capable of reducing styrofoam waste, with the highest survival rate in the P50 group.

Abstract

Penyu lekang (Lepidochelys olivacea) merupakan spesies yang terancam punah sehingga upaya konservasi berbasis data ilmiah menjadi sangat penting. Penelitian ini bertujuan untuk mengkaji pengaruh pemberian dua jenis pakan lokal ikan bleberan (Thryssa sp.) dan ikan tamban (Sardinella fimbriata) terhadap pertumbuhan tukik penyu lekang di Konservasi Alun Utara, Desa Pekik Nyaring, Bengkulu Tengah. Metode yang digunakan dalam penelitian ini menggunakan eksperimental kuantitatif dengan desain rancangan acak lengkap (RAL) dengan lima perlakuan pakan yaitu A (50% S. fimbriata, 50% Thryssa sp.), B (75% S. fimbriata, 25% Thryssa sp.), C (25% S. fimbriata, 75% Thryssa sp.), D (100% S. fimbriata), dan E (100% Thryssa sp.). Pengukuran dilakukan setiap 7 hari sekali selama empat pekan. Pengamatan eksperimental kuantitatif terhadap empat parameter pertumbuhan, yaitu massa tubuh, panjang total, panjang karapas, dan lebar karapas. Kualitas air pemeliharaan juga dipantau meliputi suhu, salinitas, pH, dan Total Dissolved Solids (TDS) dengan frekuensi pengukuran satu kali setiap pekan. Analisis dilakukan dengan menghitung selisih rata-rata pertumbuhan antar waktu pada masing-masing perlakuan pakan. Hasil penelitian memperlihatkan bahwa pakan Thryssa sp. menunjukkan tren peningkatan pertumbuhan pada keempat aspek yang diamati dibandingkan S. fimbriata, dengan pertambahan tertinggi terdapat pada kelompok yang diberi 100% Thryssa sp. Diduga kandungan nutrisi dalam Thryssa sp., terutama lemak tak jenuh dan karbohidrat, berkontribusi terhadap efisiensi metabolisme dan percepatan pertumbuhan tukik. Temuan ini mendukung pemanfaatan pakan lokal bernutrisi tinggi sebagai bagian dari strategi konservasi nutrisi tukik penyu lekang.

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

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.
