Provinsi Nusa Tenggara Timur (NTT) merupakan penghasil rumput laut kappaphycus alvarezii kedua terbesar di Indonesia berdasarkan data Badan Pusat Statistik (2016). Oleh karena itu diperlukan zonasi daerah potensial budidaya rumput laut kappaphycus alvarezii untuk pengembangan lebih lanjut. Penelitian ini bertujuan untuk menentukan daerah yang potensial untuk budidaya rumput laut kappaphycus alvarezii di Provinsi NTT berdasarkan parameter sea surface temperature (SST), salinitas, kedalaman, arus, dissolved oxygen (DO), nitrat, fosfat, klorofil-a, dan muara sungai. Penentuan kesesuaian lokasi budidaya dilakukan dengan memberikan bobot dan skor bagi setiap parameter untuk budidaya rumput laut kappaphycus alvarezii menggunakan sistem informasi geografis melalui overlay peta tematik setiap parameter. Dari penelitian ini diperoleh bahwa kadar nitrat, arus, kedalaman, dan lokasi muara sungai menjadi parameter penentu utama. Jarak maksimum dari bibir pantai adalah sekitar 10 km. Potensial budidaya rumput laut kappaphycus alvarezii ditemukan di Pulau Flores bagian barat, kepulauan di Kabupaten Flores Timur dan Alor, selatan Pulau Sumba, Pulau Rote, dan Teluk Kupang.

The increasing of malaria cases in recent years at Kecamatan Kalibawang has been suspected correspond with the conversion of farming land-use which initiated in 1993. Four years after the natural vegetation in this area were changed become cocoa and coffee commercial farming estates, the number of malaria cases in 1997 rose more than six times, and in 2000 it reached 6085. This study were aimed to observe whether there were any differences in density and diversity of Anopheles as malaria vector between the cocoa and mix farming during dry and rainy seasons. The results of the study are useful for considering the appropriate methods, times and places for mosquito vector controlling. The study activities comprised of collecting Anopheles as well as identifying the species to determine the density and diversity of the malaria vector. Both activities were held four weeks in dry season and four weeks in rainy season. The mea-surement of physical factors such as temperature, humidity and rainfall were also conducted to support the study results. Four dusuns which meet the criteria and had the highest malaria cases were selected as study location. Descriptively, the results shows that the number of collected Anopheles in cocoa farming were higher compared with those in mix horticultural farming; and the number of Anopheles species identifi ed in cocoa farming were also more varied than those in the mix horticultural farming.Key words: bionomik vektor malaria, anopheles,

<p class="Default">Penyakit kardiovaskular merupakan penyebab kematian nomor satu di dunia. Gaya hidup masyarakat terutama dalam mengkonsumsi diet yang tidak sehat dapat meningkatkan kadar LDL yang dapat menyebabkan  penyakit kardiovaskular. Rumput laut merah (<em>Kappaphycus alvarezii</em>)<em> </em>yang banyak dibudidayakan di Indonesia mengandung flavonoid dan triterpenoid yang diduga dapat menurunkan kadar LDL. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak rumput laut merah (<em>Kappaphycus alvarezii</em>) <em> </em>terhadap kadar LDL pada tikus putih (<em>Rattus norvegicus</em>) jantan galur Wistar yang diberi diet tinggi lemak. Penelitian ini adalah penelitian eksperimental murni laboratorik dengan rancangan penelitian <em>Post Test Control Group Design. </em>Sampel yang digunakan adalah 24 ekor tikus putih (<em>Rattus norvegicus</em>) jantan galur Wistar yang dibagi ke dalam tiga kelompok: kelompok yang diberi diet standar selama 28 hari (K1), kelompok yang diberi diet tinggi lemak selama 28 hari (K2), dan kelompok yang diberi diet tinggi lemak selama 28 hari dan pada hari ke-15 sampai hari ke-28 diberi ekstrak rumput laut merah (<em>Kappaphycus alvarezii</em>) dengan dosis 140mg/200grBB/hari (K3). Hasil analisis statistik <em>One Way Anova </em>menunjukkan bahwa terdapat perbedaan kadar LDL yang signifikan antara ketiga kelompok pada penelitian ini (p&lt;0,001). Kadar LDL pada K2 (=16,00±3,29) meningkat secara bermakna dibandingkan dengan K1 (=10,62±1,77). Sedangkan kadar LDL pada K3 (=6,88±2,42) menurun secara bermakna dibandingkan dengan K2. Dari hasil penelitian ini dapat disimpulkan bahwa ekstrak rumput laut merah (<em>Kappaphycus alvarezii</em>) berpengaruh terhadap kadar LDL darah pada tikus putih (<em>Rattus norvegicus</em>) jantan galur Wistar yang diberi diet tinggi lemak.</p><p><strong>Kata kunci</strong> : diet tinggi lemak, LDL, <em>Kappaphycus alvarezii</em></p>

The Impact

AbstractThe application of biosecurity in seaweed aquaculture plays an important role in reducing the impact of disease and pest outbreaks. The continuous occurrence of seaweed pests including the macroalgal epiphytes, epi-endophytic filamentous algae and biofilms on Kappaphycus farms may also potentially induce further incidences of the ice-ice syndrome. In this study, on-farm biosecurity management measures were tested on the commercially grown seaweeds Kappaphycus malesianus and Kappaphycus alvarezii during peak ice-ice season at Gallam-Gallam Village, Sabah, Malaysia. The investigation was focused on preventative control measures including the early detection of the ice-ice syndrome and pests through propagule health checks, regular cleaning of the crop thallus and associated long-line ropes and monitoring of the environment. Farm procedures and practices were also assessed in terms of their biosecurity ‘risk’ using the hazard analysis and critical control point (HCCAP) approach. Observations were replicated in two different farm management systems; one system adopted routine biosecurity measures and the other had no biosecurity measures. The results showed that the ice-ice syndrome and pest outbreak was significantly decreased by 60–75% for K. malesianus and 29–71% for K. alvarezii at the farm which adopted the routine biosecurity measures compared with the no biosecurity treatment. The biosecurity measures also significantly improved growth rate and seaweed quality. The infection levels of the epi-endophyte Melanothamnus sp. contributed to the ice-ice syndrome in K. malesianus, whilst the epiphyte coverage was correlated to the ice-ice incidence in K. alvarezii. This study provides the first evidence of biosecurity management measures significantly decreasing the incidence of the ice-ice syndrome and pests on a commercial seaweed farm.
