ABSTRAK
Kuda laut (Hippocampus kuda) adalah salah satu ikan Indonesia yang berlimpah keberadaannya, tetapi ikan tersebut belum banyak diteliti terutama dari aspek struktur anatomis alat pencernaannya. Kuda laut diharapkan dapat dikelola dan dibudidayakan di masa yang akan datang. Penelitian yang berlangsung pada bulan Mei 2006 sampai Januari 2007 bertujuan mengkaji struktur morfologis dan histologis alat pencernaan kuda laut. Sampel kuda laut diambil dari Balai Budidaya Laut, Lampung Selatan. Alat pencernaan kuda laut diamati secara makroskopis dan mikroskopis dengan pembuatan prepatat metode Paraffin, pewarnaan HE di Laboratorium Biologi Reproduksi dan Perkembangan FMIPA, UI. Hasil pengamatan dan pengukuran pada alat pencernaan kuda laut menunjukkan bahwa panjang usus kuda laut adalah 0,26 kali sampai 0.56 kali panjang total tubuhnya. Data ini menunjukkan bahwa kuda laut adalah ikan karnivora. Esofagus kuda laut sangat pendek dan lapisan mukosanya terlapisi oleh lapisan epitel berlapis gepeng. Lambung kuda laut terlapisi oleh lapisan epitel transisional. Lapisan mukosa usus juga tertutupi oleh epitel transisional. Kuda laut tidak memiliki pilorik antara lambung dengan ususnya. Hati kuda laut terletak di bagian kanan rongga abdominalis, berwana merah kecoklatan karena banyak mengandung vascular. Hati kuda laut terdiri dari tiga lobus yaitu lobus dorsalis, lobus quadratus dan lobus ventralis. Hati kuda laut adalah hepatopankreas. Pada hati, terdapat vesika felea berbentuk bulat berwarna kehijauan dengan ductus koledoksus yang bermuara di usus depan.

Keberadaan mikroplastik di perairan dapat mengancam biota di dalamnya. Penelitian dilakukan dengan tujuan menganalisis kelimpahan, bentuk, dan warna mikroplastik pada air, sedimen, insang dan saluran pencernaan ikan sapu-sapu Pterygoplichthys pardalis dari Situ Kenanga dan Situ Mahoni, Kampus Universitas Indonesia, Depok. Pengambilan sampel air dan sedimen dilakukan pada inlet, midlet, dan outlet kedua situ. Sampel air disaring menggunakan plankton net, sampel sedimen diambil menggunakan Ekman grab kemudian dikeringkan menggunakan oven, sampel P. pardalis sebanyak 15 individu diambil menggunakan cast net dari masing-masing situ, kemudian insang dan saluran pencernaannya diisolasi dan didestruksi menggunakan HNO3 65%. Tiap sampel yang diperoleh dilarutkan dengan larutan NaCl jenuh agar terjadi flotasi. Pengamatan dilakukan menggunakan mikroskop cahaya dan Sedgwick Rafter Chamber untuk meletakkan sampel, dengan mengamati bentuk, warna, dan jumlah partikel mikroplastik. Hasil penelitian menunjukkan bahwa bentuk fiber, film, fragmen, granula, serta warna transparan, hitam, biru, dan merah muda ditemukan pada semua sampel. Kelimpahan mikroplastik di Situ Kenanga pada air sebanyak 48,26 ± 23,51 partikel L-1, sedimen 45837,04 ± 36305,97 partikel Kg-1, insang 290,48 ± 154,58 partikel g-1 atau 1156,44 ± 378,69 partikel ind-1, saluran pencernaan 134,37 ± 55,72 partikel g-1 atau 1364,89 ± 339,54 partikel ind-1. Kelimpahan mikroplastik di Situ Mahoni pada air sebanyak 48,63 ± 30,21 partikel L-1, sedimen 36237,04 ± 16702,60 partikel Kg-1, insang 287,23 ± 109,40 partikel g-1 atau 1153,78 ± 324,32 partikel ind-1, saluran pencernaan 123,77 ± 34,35 partikel g-1 atau 1304,44 ± 270,90 partikel ind-1. Tidak terdapat perbedaan signifikan antara kelimpahan mikroplastik di Situ Kenanga dan Situ Mahoni pada semua sampel. ......The presence of microplastics in the water could threaten the biota there. This study was conducted to analyze the abundance, shapes, and colors of microplastics in water, sediment, gills and digestive tract of amazon sailfin catfish Pterygoplichthys pardalis from Situ Kenanga and Situ Mahoni, Universitas Indonesia Campus, Depok. Sampling of water and sediment were carried out at the inlet, midlet, and outlet of both situ. Water samples were filtered using plankton net, sediment samples were taken using Ekman grab and dried using an oven, as many as 15 individual P. pardalis samples were taken using cast net from each situ, then their gills and digestive tract were isolated and pulverized using 65% HNO3. Each sample obtained was dissolved with saturated NaCl solution for flotation to occur. Observations were made using a light microscope and Sedgwick Rafter Chamber to place each sample, by observing the shape, color, and number of microplastic particles. The results showed that the shapes of fibers, films, fragments, granules, as well as transparent, black, blue, and pink colors were found in all samples. The abundance of microplastics in Situ Kenanga water was 48.26 ± 23.51 particles L-1, sediment 45837.04 ± 36305.97 particles Kg-1, gills 290.48 ± 154.58 particles g-1 or 1156, 44 ± 378.69 ind-1 particles, digestive tract 134.37 ± 55.72 particles g-1 or 1364.89 ± 339.54 ind-1 particles. The abundance of microplastics in Situ Mahoni water was 48.63 ± 30.21 particles L-1, sediment 36237.04 ± 16702.60 particles Kg-1, gills 287.23 ± 109.40 particles g-1 or 1153, 78 ± 324.32 ind-1 particles, digestive tract 123.77 ± 34.35 particles g-1 or 1304.44 ± 270.90 ind-1 particles. There was no significant difference between the abundance of microplastics in Situ Kenanga and Situ Mahoni in all samples.

Digestive disorders rank among the most common problems faced in Indonesia, especially for the Baduy people in Banten Province. Although the Baduy live in water-rich areas, their lack of sanitation facilities and unawareness of methods of disease prevention have prompted high morbidity and mortality rates in their communities, largely due to digestive system disorders that they continue to treat with medicinal plants. This survey was undertaken to document Baduy indigenous medicinal plants that were used to treat and prevent different types of digestive system disorders in their communities using quantitative ethnobotanical approaches. Ethno medicinal data were collected from 30 informants regarding their knowledge on medicinal plants. Quantitative approaches were used to determine the use value and informant consensus factor values of collected data. The results revealed that the Baduy currently use 54 medicinal plant species belonging to 30 families to treat digestive system disorders. Additional research is required, however, to validate the function of the medicinal plants and identify their active compounds.

This is the first time a book about laparoscopy in emergency abdominal surgery has been published. Numerous articles have been published in specific surgical journals, but, until now, there has not been a book that collates all the aspects of this little-known field. The aim of this volume is to achieve a complete and easy presentation of all the implications associated with laparoscopy in emergency abdominal surgery. The book should be a manual that can be easily consulted by digestive, general, and specialized surgeons, especially in an emergency. The authors’ contributions are founded on evidence-based medicine, which give the book scientific credibility, but this is coupled with their experience of daily practice, which adds an important complementary dimension to evidence-based medicine. This is balanced by an emphasis on clarity and accessibility, because the ultimate aim of the book is educational.
