Abstract

Medical treatment of severe blood loss during labor is crucial, and the early warning indicator of postpartum hemorrhage (PPH) is essential for labor medical treatment. Measurement of blood loss conventionally looks dirty, reluctant, and less hygienic since some of the blood might be spilled out in the maternity bed, while commercially existing pads have low blood absorption capacity. A new design composite pad composed of absorbent materials including cellulose rayon, super absorbent polymer (SAP), and zeolite was fabricated and characterized. The SAP and zeolite show properties as crystalline and amorphous materials, respectively. The surface area of natural zeolite was 19.79 (m2/g). The newly fabricated composite pad showed a high blood absorption capacity (>500–600 mL) with a blood absorption rate of 55.56–85.84 mL/min (depending on the blood volume), showing better performance as compared to the commercial pads. These characteristics suggest that the new composite pad could function not only as a sanitary pad but also as an early warning indicator for PPH if the rate and blood volume reach the dangerous category (≥600 mL or at ≥13 mL/min rate).

Abstract

Water hyacinth is an aquatic plant often used as a craft product because it is attractive for its various positive properties but requires further handling, especially regarding its color. White is one of the most popular types, and the manufacturing process involves bleaching stages using chemical compounds such as hydrogen peroxide (H2O2). The use of H2O2 in the bleaching process still has consequences for the quality of the material, which becomes easily damaged, and the bleaching process, which involves the presence of sunlight or ultraviolet lamps, occurs more quickly. This research examines the relationship between the duration of soaking water hyacinth in H2O2 solution in the presence of direct light or in dark conditions on its color and tensile test strength. Based on the research results, the Hue, Saturation, and Value (HSV) color data increase the brightness based on saturation and value data. Tensile test capability testing carried out using the Universal Testing Machine (UTM) instrument showed that immersing water hyacinth in H2O2 for 4-8 minutes did not cause a significant change in tensile test capability, so it was still possible for various purposes as a raw material in the creative industry. Keywords: bleaching, hydrogen peroxide, water hyacinth, tensile strength Eceng gondok merupakan salah satu tanaman air yang sering digunakan sebagai produk kerajinan karena memiliki daya tarik pada berbagai sifat positif yang dimiliki, namun diperlukan penanganan lebih lanjut terutama pada warnanya. Warna terang merupakan salah satu tipe yang banyak digemari dan proses pembuatannya menggunakan tahapan pemutihan menggunakan senyawa kimia seperti hidrogen peroksida (H2O2). Penggunaan H2O2 pada proses bleaching masih memiliki konsekuensi pada kualitas bahan yang menjadi mudah rusak, serta proses bleaching yang melibatkan kehadiran sinar matahari maupun lampu ultraviolet akan terjadi lebih cepat. Penelitian ini bertujuan melihat hubungan antara durasi perendaman eceng gondok dalam larutan H2O2 pada kondisi kehadiran sinar secara langsung maupun dalam kondisi gelap terhadap warna dan kekuatan uji tariknya. Berdasarkan hasil penelitian ditemukan data warna Hue, Saturation, dan Value (HSV) menunjukkan kecenderungan (trend) yang baik terutama untuk data saturation dan value. Pengujian kemampuan uji tarik didapatkan bahwa perendaman eceng gondok dalam H2O2 antara 4-8 menit praktisnya tidak menyebabkan perubahan kemampuan uji tarik, sehingga masih memungkinkan untuk berbagai keperluan sebagai bahan baku di industri kreatif. Kata kunci: bleaching, hidrogen peroksida, eceng gondok, kuat tarik

Abstract

The combination of Avocado Seed Powder and Commercial Feed on the Growth Rate of Bileh Fish as an Alternative to Support Bileh Fish Farming. This study aims to determine the growth rate of bileh fish (Rasbora sp.) fed with a combination of avocado seed powder and commercial feed and to identify the optimal dose of the combination for bileh fish cultivation. The research was experimental, using a Completely Randomized Design (CRD) with three treatments and three repetitions. The treatments included different doses of the combination of avocado seed powder and commercial feed: P0 = 100% commercial feed (control), P1 = 90% commercial feed/10% avocado seed powder, P2 = 80% commercial feed/20% avocado seed powder, and P3 = 70% commercial feed / 30% avocado seed powder. The research stages consisted of preparing containers, collecting bileh fish, preparing experimental feed, conducting maintenance and observation, and collecting data. The data collected included absolute weight gain, absolute length gain, specific growth rate (SGR), and survival rate (SR) of Rasbora fish. The data were processed and analyzed using the F-test (ANOVA). The results show that the best dosage of the feed combination for Rasbora fish is treatment P3, with an absolute weight gain of 0,35%/day, a daily length growth rate of 0,4%/day, a specific growth rate (SGR) of 1,89%/day, and a survival rate (SR) of 99%.

Abstract

ABSTRAKPesisir pantai barat-selatan Aceh, khususnya Kabupaten Aceh Barat di Pangkalan Pendaratan Ikan (PPI) Ujong Baroh memiliki keanekaragam hayati yang luar biasa, terutama untuk spesies ikan pari sebagai salah satu kelompok ikan bertulang rawan dan memiliki peran dalam menjaga keseimbangan ekosistem. Keberadaan spesies tersebut mengalami penurunan akibat penangkapan berlebih, rendahnya kesadaran terkait konservasi, serta lemahnya implementasi kebijakan terhadap perlindungan ikan pari. Penelitian ini bertujuan untuk menganalisis sebaran spesies pari yang ditangkap para nelayan beserta jumlahnya, analisis kondisi yang memungkinkan dilakukan untuk konservasi, dan analisis kebijakan yang layak dilakukan untuk memastikan keberlangsungan hidup ikan pari. Penelitian dilakukan melalui survei langsung di PPI Ujong baroh untuk melakukan observasi, wawancara dan lain-lain. Analisis data dilakukan dengan pemaparan informasi mendasar terkait jumlah dan sebaran spesis pari yang ditangkap oleh masyarakat, analisis Strengths, Weakness, Opportunities, dan Threats (SWOT) untuk mengidentifikasi strategi konservasi yang tepat, serta kondisi yang mungkin untuk diambil sebagai tindaklanjutnya. Hasil observasi menunjukkan terdapat 11 jenis ikan pari yang sering ditangkap oleh nelayan di PPI Ujong Baroh, meliputi dua jenis ordo berbeda yaitu Myliobatiformes dan Rhinopristiformes. Hampir seluruh jenis pari tersebut berada dalam status Terancam Punah, bahkan spesies pari barong (Rhina ancylostoma) berada dalam status yang lebih mengkhawatirkan. Hasil analisis SWOT menunjukkan posisi strategi pengelolaan ikan pari saat ini berada dalam Kuadran III (strategi defensif), dimana posisi kelemahan dan ancaman lebih dominan dibandingkan kekuatan dan peluang. Kelemahan internal tersebut berasal dari berbagai aspek nelayan, penjual dan pemerintah. Selain itu, ancaman terhadap keberlangsungan hidup pari juga cukup besar karena permintaan pasar yang tinggi serta maraknya praktik penangkapan ilegal/destruktif. Meskipun hasil analisis SWOT menunjukkan posisi yang lemah dan memerlukan strategi bertahan, kekuatan dan peluang yang tersedia tetap memiliki peran penting jika dimanfaatkan secara strategis, sehingga arah kebijakan berfokus pada penguatan faktor pendukung, serta memperbaiki kelemahan dan mengantisipasi ancaman. Beberapa faktor kekuatan yang dapat dioptimalkan berupa keberadaan fasilitas PPI Ujong Baroh, pengalaman nelayan lokal dalam praktik penangkapan, dan dukungan dari pemerintah daerah dalam bentuk kebijakan kelembagaan. Kata Kunci: strategi, pengelolaan, berkelanjutan, kepunahan , SWOT.ABSTRACTThe southwestern coastal region of Aceh, particularly in West Aceh Regency at the Ujong Baroh Fish Landing Base (PPI), is home to remarkable biodiversity, especially among ray species, which are cartilaginous fish playing a vital role in maintaining ecosystem balance. However, the presence of these species  has  been  declining  due  to overfishing,  low awareness  of conservation  efforts,  and  weak enforcement of protective regulations. This study aims to analyze the distribution and quantity of ray species caught by local fishermen, assess feasible conservation measures, and evaluate policy options to ensure the sustainability of ray populations. Field research was conducted at PPI Ujong Baroh through direct surveys, observations, interviews, and other qualitative methods. Data analysis involved a presentation of basic information on species diversity and catch distribution, a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis to identify appropriate conservation strategies, and a review of potential follow-up actions. Observations revealed 11 ray species commonly caught by local fishermen, encompassing two distinct orders: Myliobatiformes and Rhinopristiformes. Nearly all of these species are classified as Threatened, with the wedgefish (Rhina ancylostoma) listed in a more critical conservation status. The SWOT analysis indicates that current ray management strategies fall into Quadrant III (defensive strategy), where weaknesses and threats outweigh strengths and opportunities. These internal weaknesses stem from factors involving fishers, traders, and governmental institutions. Moreover, the sustainability of ray populations is under significant threat due to high market demand and the prevalence of illegal or destructive fishing practices. Despite these challenges, the identified strengths and opportunities can still play a strategic role if leveraged effectively. Therefore, policy direction should focus on reinforcing supportive factors while addressing weaknesses and mitigating threats. Key strengths include the existing infrastructure at PPI Ujong Baroh, the experience of local fishermen, and support from local governments in the form of institutional policies.Keywords: strategy, management, sustainability, extinction, SWOT

Abstract

Seagrass beds are one of the coastal ecosystems that have an important role in maintaining the balance of the marine environment. Indonesia is known for its rich seagrass species but not much has been reported, especially in Aceh waters.This study aims to identify and analyse the distribution and condition of seagrass health through the percentage cover and dominance of seagrass species in Pulau Banyak District, Aceh Singkil Regency. Seagrass research was conducted in July 2024 at 3 different stations, namely Nago, Matahari and Panjang Islands. The research method used was the method of drawing a 100 m long line transect, with each station being repeated 3 times at 50 m, so that the seagrass area observed was 100 m2. Differences in the condition of the aquatic environment showed differences in the presence of seagrass species found. A total of 4 seagrass species were recorded in this study, namely Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata and Halophila ovalis. There is a difference in the number of seagrass species found in the 2015 and 2023 time periods, the 2024 survey recorded 4 species from the previous 5 seagrass species. The highest percentage of seagrass cover was found on Nago, Matahari and Panjang Islands with percentages of 19.98%, 3.69% and 1.23% respectively. The highest overall seagrass species cover was T. hemprichii at 60.268%, while the lowest seagrass species was H. ovalis at 3.534%. Based on the results of the analysis of the percentage of seagrass cover of the entire research station, it is concluded that seagrass in the waters of Pulau Banyak is included in the category of sparse cover, with poor condition status (≤29.9).
