Abstract

Abstract: Microplastics have become a global concern due to their wide distribution and ecological effects. Understanding the interactions between microplastics and ecosystems is important for environmental risk assessment. This study analyzed the abundance and distribution of microplastics in Lake Singkarak. Substantial microplastic research is still lacking for freshwater biota, so a study was conducted to determine the level of microplastic pollution in bilih fish tissue. The fish's size, weight, and sampling point were studied about microplastic uptake through two channels, digestion and respiration. From the results, the types of polymers identified in this study were polyethylene, polyvinyl chloride, and polyethylene terephthalate. Overall, 7.14% - 23.53% (average = 11.48%) of microplastics were identified in the D tract of bilih fish from sixteen different sampling points. While 7.69% - 17.39% (average = 11.85%) of microplastics were identified in the respiration of bilih fish. The highest percentage of the abundance of microplastic forms in the digestions identified was fiber at 70.42% and 66.82% in the digestions. At the same time, The lowest percentage identified was fragmented, with an average abundance of 29.58% in digestion and 33.32% in respiration. In conclusion, this study reveals the presence and impact of microplastics in Lake Singkarak, West Sumatra, on the bilih fish (Mystacoleucus padangensis). By examining the fish's digestive and respiratory systems and using FT-IR Spectroscopy, the research highlights the ecological and economic implications of microplastic pollution. These findings emphasize the need for targeted conservation and management strategies.Abstrak: Mikroplastik telah menjadi perhatian global karena distribusinya yang luas dan efek ekologisnya. Pemahaman tentang interaksi antara mikroplastik dengan ekosistem dinilai penting untuk penilaian risiko lingkungannya. Penelitian ini menganalisis kelimpahan dan distribusi mikroplastik di Danau Singkarak. Penelitian mikroplastik secara substansial masih sedikit untuk biota air tawar maka dilakukan penelitian untuk menentukan tingkat polusi mikroplastik pada jaringan ikan bilih. Ukuran, berat, dan titik sampling ikan diteliti dalam kaitannya dengan jerapan mikroplastik melalui dua saluran, yaitu digestif (pencernaan) dan respirasi (pernapasan). Dari hasil penelitian, jenis polimer yang teridentifikasi dalam penelitian ini adalah jenis polietilen, polivinil klorida, dan polietilen tereftalat. Secara keseluruhan 7,14% - 23,53% (rata-rata = 11,48%) mikroplastik teridentifikasi pada digestif ikan bilih dari enam belas titik sampling yang berbeda. Sementara 7,69% - 17,39% (rata-rata = 11,85%) mikroplastik teridentifikasi pada respirasi ikan bilih. Persentase kelimpahan bentuk mikroplastik tertinggi pada digestif yang diidentifikasi adalah fiber sebesar 70,42% dan 66,82% pada digestif. Sementara persentase terendah yang diidentifikasi adalah fragment dengan rata-rata kelimpahan sebesar 29,58% di digestif dan 33,32% di respirasi. Sebagai kesimpulan, penelitian ini mengungkap keberadaan dan dampak mikroplastik di Danau Singkarak, Sumatera Barat, pada ikan bilih (Mystacoleucus padangensis). Dengan memeriksa sistem pencernaan dan pernapasan ikan serta menggunakan Spektroskopi FT-IR, studi ini menunjukkan implikasi ekologis dan ekonomi dari polusi mikroplastik. Temuan ini menekankan perlunya strategi konservasi dan pengelolaan yang terarah.

Abstract

Stunting is a chronic malnutrition problem caused by inadequate nutritional intake over a long period of time, resulting in impaired optimal physical and cognitive development. The problem of stunting and malnutrition requires coordination between various parties to overcome it. In Agam Regency, especially Nagari Kamang Hilia, the stunting rate is still relatively high, with a prevalence of 24.6%, according to the latest Indonesian Nutrition Status Survey (SSGI). One of the factors influencing this is the high cost of nutritious food, which reduces the interest of mothers in serving healthy menus for the family. Therefore, education and training on nutritious food processing with alternative food sources is needed to increase public understanding. This program targets posyandu cadres and PKK mothers as the main targets, with the aim of providing knowledge about the importance of fulfilling nutrition to prevent stunting and malnutrition. The results of this activity are expected to increase awareness and interest of mothers in processing nutritious food that is attractive and liked by families, especially children.

Abstract

Sambiloto, often referred to as the “Raja Pahit”, is a plant belonging to the Acanthaceae family. This plant is known to produce secondary metabolite compounds with various biological benefits, including antioxidant properties. Antioxidant compounds have been shown to counteract the formation of free radicals that are harmful to the body. The antioxidant activity of the Sambiloto plant can be evaluated using endophytic fungi associated with it. This study aimed to identify secondary metabolite compounds and evaluate the antioxidant activity of AS-3 Fungus isolated from the Sambiloto roots. Phytochemical analysis revealed that the ethyl acetate extract of AS-3 contained terpenoids, flavonoids, and alkaloids. In addition, the antioxidant activity test showed promising results, with an IC50 value of 10.225 ppm, indicating high antioxidant potential. This is the first report on the phytochemical screening and antioxidant activity test of the ethyl acetate extract of AS-3 fungus isolated from Sambiloto roots.

Abstract

Microplastic pollution accumulates in the marine environment, thus impacting the health of marine organisms. The purpose of this study was to analyze and identify the abundance and characteristics of microplastics in Horse-Eye Jack fish (Caranx latus) in coastal Bungus Bay, West Sumatra. Fish samples were taken at three different locations, namely, Sako beach, Caroline Beach, and the east side of Bungus Bay. The average abundance of microplastics in horse-eye Jack fish samples in digestive is 21.63 ± 3.99 particles/fish, and in respiration, 9.23 ± 1.92 particles/fish. The shape identified forms of microplastics are fibers, films, fragments, granules, and foam, and the dominant color of microplastics is red. The most common size of microplastics found was <0.5 mm. FT-IR spectroscopy analysis showed that the polymer types of microplastics found were PE, PVC, PET, and PS. Statistical tests showed differences between the abundance of microplastics in two pathways of microplastic uptake (digestive and respiration), and the sampling location P<0.05. The results showed that microplastics were found in all Horse-Eye Jackfish samples in Bungus Bay, West Sumatra.These findings highlight microplastics' harm to the marine ecosystem and the necessity of managing plastic waste if we hope to avoid future plastic pollution catastrophes
