Abstract

Gastropoda merupakan komponen penting dalam ekosistem mangrove. Spesies ini banyak ditemukan baik di batang, akar maupun sedimen di ekosistem mangrove. Selain itu, gastropoda juga diduga berperan dalam proses dekomposisi serasah mangrove. Walaupun telah ada penelitian terkait hal ini, namun belum banyak penelitian terkait gastropoda, terutama di pesisir Kabupaten Situbondo. Terlebih lagi sebagian wilayah mangrove Situbondo termasuk Zonasi Kawasan Koservasi Jawa Timur, sehingga sangat penting untuk dilakukan pemutakhiran data. Dengan demikian penelitian ini bertujuan untuk mengetahui keanekaragaman gastropoda di Pesisir Kabupaten Situbondo beserta peranannya dalam ekologi maupun ilmu pengetahuan. Pengambilan data dilakukan dengan metode metode transek kuadran di 3 stasiun, yaitu Pantai Kampung Kerapu, Pantai Cemara Indah dan Pantai Bama. Hasil penelitian keanekaragaman gastropoda di pesisir Kabupaten Situbondo diperoleh 9 spesies gastropoda yang tergolong ke dalam 6 famili yakni Assimineidae, Ellobiidae, Planaxidae, Potamididae, Neritidae, dan Littorinidae. Spesies Pirenella cingulata adalah spesies dengan jumlah individu yang paling banyak ditemukan. Hasil penelitian juga menunjukkan nilai keanekaragaman yang paling tinggi (H’ = 1,14) terdapat di Pantai Kampung Kerapu, dominansi yang paling tinggi (D = 1) di Pantai Cemara Indah dan keseragaman tertinggi (e = 0,85) di Pantai Bama. Berdasarkan hasil yang didapat, perlu penelitian lanjut dan monitoring secara rutin mengenai keanekaragaman gastropoda terutama di Pantai Kampung Kerapu dan Pantai Cemara Indah, mengingat data yang masih terbatas dan semakin tingginya aktivitas manusia yang memungkinkan adanya pengaruh terhadap kelestarian keanekaragaman serta peranan gastropoda di ekosistem mangrove.

Abstract

The Culex pipiens mosquito is one of the insects that carries diseases, especially filariasis. Mosquito control can be done using insecticides, either in the form of mosquito coils, electricity, or anti-mosquito lotion. However, the safety of insecticides on the market needs to be questioned because they contain chemicals. Therefore, alternative methods based on natural ingredients are needed, one of which is srikaya seeds. Therefore, this research was carried out to measure the biolarvicidal activity of sugar apple seed extract against Culex pipiens mosquito larvae. This research is an experimental study with treatment in the form of a concentration of srikaya seed extract, consisting of 0%, 3%, 6%, 9%, 12% and 15% with 3 repetitions. The data obtained was the average number of Culex pipiens mosquito larvae that died as a result of the treatment given. The percentage of larval death data was then calculated and the data was analyzed statistically using one-way anova with calculations using SPSS 23 software. The results of the study showed that differences in the concentration of sugar apple seed extract had a significant influence on the mortality of Culex pipiens mosquito larvae, where a concentration of 15% gave the highest average larval death. but not significantly different from concentrations of 12%, 9%, and 6%.

Abstract

ABSTRAKTujuan peneletian ini untuk mengetahui pengaruh pemberian tepung daun pepaya (Carica papaya L) dengan dosis yang berbeda pada pakan buatan terhadap pertumbuhan berat mutlak ikan gurami (Osphronemus gouramy) dan untuk mengetahui penambahan dosis tepung daun pepaya pada pakan buatan terhadap pertumbuhan berat mutlak ikan gurami (Osphronemus gouramy). Penelitian ini menggunakan metode eksperimen Rancangan Acak Lengkap (RAL) dengan 5 perlakuan 5 ulangan. Perlakuan yang diuji penambahan daun pepaya (Carica papaya L) dengan dosis berbeda yaitu; 0 gr/kg, 20 gr/kg, 30 gr/kg, 40 gr/kg and 50 gr/kg. Sampel menggunakan benih ikan gurami (Osphronemus gouramy) dengan Panjang 5 cm. Hasil penelitian menunjukkan bahwa pemberian tepung daun papaya (Carica papaya L) dengan dosis yang berbeda berpengaruh nyata terhadap pertumbuhan berat mutlak ikan gurami (Osphronemus gouramy). Perlakuan E memberikan hasil tertinggi sebesar 4,50 gr/ekor. Data kualitas air diperoleh suhu air berkisar 27.2 ºC – 27.6 ºC, derajat keasaman 7,3 – 7,7 dan oksigen terlarut 5,6 – 5,9 ppm.Kata Kunci: ikan gurami, daun pepayaABSTRACTThe purpose of this study was to determine the effect of giving papaya leaf flour (Carica papaya L) with different doses of artificial feed on the absolute weight growth of gouramy (Osphronemus gouramy) and to determine the additional dose of papaya leaf powder on artificial feed (Carica papaya L) on the growth of absolute weight of gouramy (Osphronemus gouramy).

Abstract

This literature review aimed to: (1) identify edible fungal species with potential applications as mycelium-based packaging materials; (2) compare mycelial characteristics in terms of substrate compatibility, mechanical properties, thermal stability, water absorption, and food safety; and (3) recommend the most suitable species for the development of biodegradable food packaging. A systematic scoping review was conducted following the framework of Arksey & O’Malley (2005) and PRISMA-ScR guidelines. Literature searches were performed in Scopus, Web of Science, ScienceDirect, and Google Scholar for publications from 2015 to 2024 using the keywords mycelium composite, mycelium-based foam, Pleurotus packaging, and biodegradable packaging fungi. Of the 312 articles initially identified, 47 met the inclusion criteria, namely empirical studies that assessed at least two material parameters and were published in English or Indonesian. The findings indicate that Pleurotus ostreatus exhibits several advantages, including rapid colonization time (7–14 days), suitable mycelium density (25–75 kg/m³), tensile strength (0.18–0.43 MPa), low thermal conductivity (0.03–0.07 W/m·K), and a high biodegradation rate in soil (60–90% per week). Pleurotus citrinipileatus demonstrated slightly lower mechanical performance but greater adaptability to mixed substrates. Both species are classified as generally recognized as safe (GRAS) by the FDA and do not produce significant levels of mycotoxins under standard cultivation conditions. Overall, P. ostreatus shows strong potential as a biodegradable packaging material to replace expanded polystyrene (EPS). However, industrial-scale experimental validation, food contact migration testing, and production standardization remain essential before commercial application.
