Abstract

Kajian performa bilateral simetri berdasarkan morfometrik standar dan meristik telah dilakukan terhadap kepiting Albunea symmysta dari pantai Parangkusumo dan Cilacap. Penelitian menggunakan metode survei dan pengambilan sampel secara purvosive sampling. Pengukuran dilakukan terhadap antennula dan dactylus pereopod I, sedangkan penghitungan dilakukan terhadap jumlah duri anterolateral serta segmen antenna. Karakter meristik dianalisis deksriptif berdasarkan nilai minimal, maksimal, rata-rata dan standar deviasi. Terhadap data morfometri dilakukan uji T. Hasil penelitian menunjukkan adanya variasi morfometrik dan meristik pada performa kepiting dari kedua lokasi pengambilan sampel dan ketidaksimetrisan morfometrik lebih banyak dialami dibandingkan meristik. Munculnya perbedaan pertumbuhan bilateral yang terjadi pada kepiting tersebut kemungkinan berkaitan dengan kondisi genetis, kendala lingkungan dan tekanan predator.

Abstract

Cilacap Bays, critical nesting areas for sea turtles, face growing habitat disturbances from tourism. However, studies on nesting suitability in these regions remain scarce. This research assesses the abiotic factors influencing sea turtle nesting in Cilacap Regency, Indonesia, across eight observation stations. Key ecological parameters—land surface temperature (28°C - 36.3°C), pH (mean 6.8), sand particle size (0.212-0.500 mm), beach slope (11.50%-20.99%), and beach width (28.8m-81.8m)—were evaluated. The results highlight Sidaurip Beach as the most suitable for nesting due to optimal environmental conditions, with Station (SP1) being particularly favorable for producing male hatchlings due to its suitable 28°C temperature. These findings suggest targeted egg relocation to SP1 could help address gender imbalances, ensuring long-term population sustainability. This research provides valuable insights for sea turtle conservation and supports future policy efforts to protect nesting sites in Cilacap amidst growing environmental pressures

Abstract

Giant gourami has been widely cultivated across Java Island, including in Banyumas and Ciamis Regencies. However, information genetic characters of both populations were not available. Therefore, this study aims to evaluate molecular characteristics of giant gourami from Ciamis and Banyumas. A purposive random sampling was done Molecular characterization was performed using randomly amplified polymorphic DNA. Molecular data were analyzed statisticaly. Both populations were genetically different and they have high genetic diversity within population. Based on the high genetic diversity of giant gourami from Ciamis and Banyumas populations, it would be very good to crossbreed between those both to produce high quality offspring.

Abstract

Roket FFAR (Folding Fin Aerial Rocket), merupakan roket taktis dengan diameter dan panjang, berturut-turut 70 mm dan 680 mm. Roket ini dapat digunakan, baik dari darat ke darat, udara ke udara, dan bahkan dari udara ke darat. Roket FFAR 2.75”, mempunyai 4 (empat) buah nosel kecil-kecil sejenis (Multi Nosel) yang pemasangannya diatur sedemikian rupa, sehingga satu dengan lainnya membentuk sudut tertentu. Dengan posisi nosel-nosel seperti ini, dapat menghasilkan efek puntir (sebagai mana gerak laju peluru) pada saat terbang, sehingga roket ini mempunyai jangkauan horizontal sekitar 8 km pada sudut elevasi 40º. Roket substitusi FFAR (RX-70) mempunyai 1 (satu) nosel (Nosel Tunggal), berbahan bakar propelan padat jenis komposit, sementara FFAR asli menggunakan tipe double base. Paper ini membahas simulasi perancangan sistem propulsi, pembuatan dan pengujian (statik maupun terbang) roket RX-70 dengan nosel tunggal sebagai pengganti FFAR nosel jamak. Dari hasil uji terbang yang telah dilaksanakan mulai tahun 2004 di Pandanwangi-Jawa Timur dan dilanjutkan di Pameugpeuk-Jawa Barat, diketahui bahwa roket RX-70 mempunyai jangkauan horizontal 7,8 km pada sudut elevasi 40°, terjadi penyimpangan 2,5 % dari rancangan.

Abstract

Cadangan asbuton di Pulau Buton Sulawesi yang sangat besar, masih belumdimanfaatkan secara maksimal untuk keperluan pembangunan, khususnya jalan, baik dalam bentuk asbuton butir maupun aspal cair. Aspal cair hasil ekstraksi asbuton, tersusun dari Saturates, Asphaltenes, Resins dan Aromatics, pada dasarnya merupakan campuran hidrokarbon baik aromatik maupun alifatik, dan berbentuk cairan sangat kental berwarna hitam dan memiliki sifat lengket. Bahan bakar roket padat atau yang disebut propelan padat terdiri dari fuelbinder (15-20%), metal-fuel (2-5%), oksidator (75-80%) sebagai sumber oksigen dan additives lainnya (2-5%). Bahan baku tersebut diolah melalui beberapa tahapan proses, sehingga menghasilkan bentuk batang propelan (propellant grain) dengan spesifikasi yang sesuai dengan yang diperlukan dalam perancangan. Aspal cair dari asbuton yang memiliki sifat rekat yang baik, diharapkan dapat dimanfaatkan sebagai fuel-binder dalam propelan padat jenis komposit. Oleh karena, aspal cair berupa cairan yang sangat kental, maka akan mengalami beberapa kendala dalam proses pencampuran dengan oksidator maupun bahan padat lainya dalam pembentukan batang propelan, karena tidak akan bisa menampung jumlah oksidator yang cukup memadai. Sebagai akibatnya, kinerja yang dihasilkan, masih jauh dari yang diharapkan, bila dibandingkan dengan propelan komposit yang sekarang banyak digunakan, seperti poli-butadiena.

Abstract

Phylogenetic assessment of the giant clams need to be improved using various genetic markers since their relaionships are plagued by inconsistency result of several studies. This is especially true for the species under sub-genus Chametrachea. Here we studied the phylogeny of the giant clams using amino acid sequence of the mitochondrial COI gene. This study is aimed to assess and better understand the relationships of the giant clams, especially for three species under subgenus Chametrachea. The result showed close proximity between T. crocea and T. squamosa and between T. maxima and T. gigas.  However, amino acids sequences of cytochrome c oxidase I gene was not strong enough to discriminate between T. crocea and T. squamosa. The majority of mutations were hydrophobic to hydrophilic amino acids.

Abstract

Abstract Mud clams Polymesoda erosa in the Segara Anakan Cilacap are highly exploited by the local communities for daily consumption. This is presumed causing population decline and potentially causing loss of genetic diversity. Genetic diversity level within population can be obtained by population genetic study using molecular marker such as randomly amplified polymorphic DNA (RAPD). Here we amplified RAPD marker using ten arbitrary primers to assess genetic diversity of P. erosa population in the Segara Anakan Cilacap to provide genetic data for its sustainable use. The result proved that the used RAPD marker has high polymorphisms. The mud clam population was also showed a high level of heterozigosity and genetic diversity.  This has important implication for the management plan towards ustainable use of P. erosa in the Segara Anakan Cilacap.   Key words: mud clam, RAPD, polymorphism, genetic diversity

Abstract

Catfish species are commercially cultivated freshwater fish by fish farmer. Formerly, only one species of catfish had been cultivated, namely local catfish (walking catfish) Clarias batrachus.  However, since 1985, local catfish was replaced by a new commodity from Africa called African catfish (C. gariepinus).  In 2004, BBPBAT Sukabumi had introduced a new strain of catfish, namely Sangkuriang catfish.  Taxonomic analysis needed, especially for Sangkuriang catfish using molecular marker, in order to get a clearer picture about its genetics departure from their parental, so their taxonomic status and relationships with local and African catfish is clearer.  One of the molecular markers is randomly amplified polymorphic DNA (RAPD) markers. Species status defined based on the presence and absence of specific band on each catfish.  Phylogenetics relationships was inferred from phylogenetic tree which was built using UPGMA tool as implemented in NTSYS software based on the similarity of RAPD band pattern. The result showed that Sangkuriang and local catfish had specific RAPD markers, while African catfish was not. This means that all RAPD markers of African catfish were shared with those of two others catfish. Local catfish phylogenetically distantly related to African and Sakuriang catfish. Only one individual of African catfish (D4) genetically close related to Sangkuriang catfish while the rest individuals of African catfish genetically closed related to green catfish. This means that African catfish showed very divergence genetic constituent.    Key words: catfish, molecular identification, phylogenetic relationships, RAPD

Abstract

Cijalu River is located in the western part of Cilacap Regency, Central Java Province. The river flows through forestry, housing, and farming areas. These conditions lead to the prediction that its physico-chemical characteristics may have been altered, potentially affecting the fish species inhabiting the river. This study aimed to collect data on fish species inhabiting the Cijalu River and analyze their distribution. A survey method was conducted using a clustered random sampling technique. The river was divided into three sections: upstream, midstream, and downstream. Species diversity was measured based on the number of species recorded, while distribution was determined by the presence of fish species in each sampling site. Nineteen fish species belonging to ten families were identified from the Cijalu River. The ten families recorded were Anabantidae, Bagridae, Balitoridae, Channidae, Cichlidae, Cyprinidae, Loricariidae, Osphronemidae, Poecilidae, and Sisoridae. Cyprinidae represented the family with the highest number of species (6 species), followed by Channidae (3 species), Bagridae (2 species), and Osphronemidae (2 species). The remaining families were each represented by one species. Different patterns of fish distribution were observed during the study. Glyptothorax platypogon and Channa gachua were found only in the upstream area, while Anabas testudineus was collected only from the downstream section. Other species were found either from the midstream to downstream areas or throughout the entire river system. The variation in species distribution may be associated with changes in physico-chemical characteristics from upstream to downstream, particularly substrate type and water velocity.
