Abstract

Phyrella is a genus of sea cucumbers that holds significant economic value and is widely exported for human consumption. Despite its importance, knowledge regarding the species diversity of Phyrella in Indonesian waters, particularly in Demak Waters, remains limited. This study aims to identify the Phyrella species found in this region through morphological analysis of spicules. The identification process involved examining the spicules present in the calcareous ring and various body parts, including the anterior, posterior, ventral, and dorsal regions. Spicules were observed using a light microscope at 100x magnification after dissolving body tissues with a sodium hypochlorite (NaOCl) solution to isolate their structure. The findings revealed four distinct spicule shapes: buttony, mensal, barbed, and barbed wire rod. These spicule characteristics are essential in distinguishing Phyrella species. Based on these morphological features, the sea cucumber species found in Demak Waters was identified as Phyrella fragilis. The results contribute to taxonomic studies and provide insights into the ecological role of Phyrella fragilis in marine ecosystems. Furthermore, this species has potential applications in the food, pharmaceutical, and cosmetic industries due to its rich nutritional content and bioactive compounds. Understanding its morphology and distribution can aid conservation efforts and sustainable resource management.

Abstract

Synthetic plastic is commonly used daily, but its non-biodegradable nature poses a significant environmental threat. Therefore, it is urgent to explore sustainable alternatives such as bioplastics. Alginate, a polysaccharide, is a promising raw material for bioplastics. However, its poor elasticity characteristic necessitates the addition of other polysaccharides, such as carrageenan, to improve bioplastics' mechanical properties. This research aims to determine the characteristics (physical and mechanical properties) of bioplastics made from a mixture of alginate and kappa-carrageenan. The laboratory experimental methods were applied with a completely randomized design. The treatments are mixtures of alginate and k-carrageenan in the following ratios: 10:0 (A10K0), 8:2 (A8K2), 6:4 (A6K4), 4:6 (A4K6), 2:8 (A2K8), 0:10 (A0K10). The characteristics of bioplastic films measured were thickness, water resistance, tensile strength, elongation, and appearance. The optimal bioplastic formulation (4:6 ratio of k-carrageenan to alginate) exhibited a film thickness of 138.3 µm, 16.6% biodegradability, tensile strength of 22.965 N/mm², and 2.73% elongation. The scanning electron microscope showed that the surface structure of bioplastic A4K6 made fromthe ratios of k-carrageenan and alginate of 4:6 had fewer structure cracks and more surface smoothness.

Abstract

Sediment is a collection of particles that come from weathering both soil and rock, biological and an anthropogenic process. Sediment flows from upstream to downstream areas. Topographic conditions are one of teh factors in sedimen distribution. The topography in the Wonorejo area tends to be low because it is located in a coastal area. The purpose of this study is to determine the effects of topographic changes in Wonorejo on the distribution of sediments in the area. The method used in this study is descriptive method by collecting data including primary data and secondary data. The primary data used are Landsat 7 and Landsat 8 satellite imagery, while the secondary data used is in the form of Surabaya village administration map data, Surabaya DEM data and Indonesian SHP data. Data processing was performed using ArcGIS 10.3 software. The results indicated that the topographic conditions of the region did not have a significant influence on the distribution of sediments in the Wonorejo area. The distribution of sediment in those area was more influenced by hydro-oceanographic factors such as currents, tides and waves. Other factors that influence are anthropogenic factors such as development and land conversion.

Abstract

Perairan Banggai merupakan salah satu laut yang memiliki upwelling atau fenomena kenaikan massa air pada periode tertentu. Peristiwa ini menyebabkan meningkatnya kandungan nutrien pada perairan disebabkan adanya proses pengadukkan massa air menuju kolom atas perairan yang mempengaruhi kelimpahan produsen primer dan produsen sekunder, salah satunya zooplankton dari Famili Acartiidae. Penelitian mengenai keberadaan dan kelimpahan spesies zooplankton belum banyak dilakukan di perairan bagian timur, terutama studi mengenai spesies-spesies dari Famili Acartiidae. Berdasarkan keterangan di atas, perlu adanya pengkajian keberadaan dan kelimpahan Acartiidae. Sampel zooplankton diperoleh dari proses pengambilan  di 35 stasiun secara aktif vertikal menggunakan plankton net. Pengamatan dan pengambilan foto spesies plankon dilakukan di bawah Mikroskop Stereo Olympus SZ61 yang disesuaikan dengan ukuran zooplankton dengan perbesaran 30x sampai 45x. Hasil pencacahan diolah menggunakan Ms. Office Excel 2016 (Excel 16) untuk mengetahui jumlah keberadaan dan kelimpahan Famili Acartiidae. Terdapat 7 spesies famili Acartiidae dari genus Acartia dan Acartiella yang didapatkan di Perairan Banggai, Sulawesi Tengah, yaitu Acartia clausi, Acartia longiremis, Acartiella faoensis, Acartiella gravelyi, Acartiella minor, Acartiella natalensis, dan Acartiella tortaniformis. Spesies dengan sebaran distribusi terbesar atau memiliki kemunculan terbanyak adalah dari genus Acartia dengan Acartia clausi muncul di 14 stasiun. Total keberadaan famili Acartiidae di Perairan Banggai sebanyak 41 individu, meliputi 35 betina dan 6 jantan dengan rata-rata di semua stasiun penelitian sebanyak 2 individu.

Abstract

Penelitian ini bertujuan menganalisis pengaruh overconfidence, anxiety traits, dan risk tolerance terhadap keputusan investasi Generasi Z, serta menguji peran financial literacy sebagai variabel moderasi. Data dikumpulkan melalui kuesioner dan dianalisis menggunakan SEM-PLS. Hasil penelitian menunjukkan bahwa overconfidence dan risk tolerance berpengaruh positif terhadap keputusan investasi, sedangkan anxiety traits (kecamasan) berpengaruh negatif. Temuan paling menarik adalah bahwa financial literacy justru melemahkan hubungan risk tolerance dengan keputusan investasi. Hasil ini bertentangan dengan hipotesis awal dan pandangan umum bahwa literasi keuangan selalu meningkatkan keberanian berinvestasi. Penjelasan temuan ini dapat dikaitkan dengan expected utility theory, di mana individu rasional dengan literasi keuangan tinggi lebih berhati-hati karena memahami potensi risiko dan kerugian. Temuan ini memberikan perspektif baru bahwa literasi keuangan bukan hanya meningkatkan kemampuan mengambil keputusan investasi, tetapi juga dapat menumbuhkan sikap kehati-hatian yang berlebihan sehingga mengurangi kecenderungan mengambil risiko. Implikasi praktis dari hasil penelitian ini penting bagi lembaga keuangan, regulator, dan program edukasi keuangan agar materi literasi tidak hanya menekankan risiko, tetapi juga membangun kepercayaan diri yang terukur dalam berinvestasi.

Abstract

Teripang merupakan salah satu sumberdaya hayati laut yang banyak terdapat di perairan P. Nyamuk dan Parang terutama untuk jenis Stichopus sp., yang merupakan jenis dengan nilai ekonomis tinggi. Namun produksi teripang saat ini menurun drastis. Untuk itu perlu dilakukan suatu upaya untuk meningkatkan produksi teripang yaitu dengan jalan budidaya, mulai dari produksi benih, pembesaran, sampai teripang siap jual. Berdasarkan permasalahan dan situasi kelompok mitra yang ada maka metodologi solusi masalah yang ditawarkan adalah melakukan percontohan budidaya teripang. Target luaran yang dicapai pada program pengabdian ini adalah alih teknologi budidaya teripang, perbaikan produksi teripang dari usaha penangkapan menjadi usaha budidaya yang mendukung konservasi sumberdaya teripang itu sendiri. Keberhasilan dari program ini dapat dilihat dari jumlah peserta yang mengikuti penyuluhan sebesar 70 % anggota yang giat melakukan uji coba fission pada teripang yang merupakan salah satu upaya pengalihan dari nelayan pengambil teripang menjadi pembudidaya teripang.
