Pantai Pangandaran merupakan salah satu objek wisata pesisir yang terletak di Kabupaten Pangandaran, Provinsi Jawa Barat dan merupakan salah satu obyek wisata unggulan di Provinsi Jawa Barat. Tetapi wisata di Pantai Pangandaran memiliki potensi bahaya fisik dan dalam beberapa kasus menimbulkan korban jiwa. Riset ini bertujuan untuk mengidentifikasi potensi bahaya fisik pantai bagi keselamatan pengunjung, menilai tingkatan risiko dari potensi bahaya fisik pantai bagi keselamatan pengunjung, dan menentukan penyebab tingginya risiko wisata di Kawasan Wisata Pantai Pangandaran. Metode yang digunakan riset ini adalah metode assessment. Data yang digunakan pada assessment tingkat risiko pantai yaitu: jumlah pengunjung, jumlah lifeguard, panjang pantai, jumlah rambu, penggunaan lifejacket, kecelakaan wisatawan, tipe pantai, dan tinggi gelombang. Hasil riset menunjukkan Kawasan Wisata Pantai Pangandaran termasuk kedalam tipe pantai longshore bar and trough. Kawasan Wisata Pantai Pangandaran termasuk kedalam kategori multiple fatalities dengan nilai R (tingkat risiko) lebih dari 200 di semua pantai pada periode low season ataupun high season. Khusus Pantai Barat pada periode high season kategori menurun menjadi fatal. Terdapat perbedaan nilai R yang signifikan pada kedua periode. Perbedaan nilai R menunjukan Kawasan Wisata Pantai Pangandaran relatif lebih aman pada periode high season. Penyebab utama dari tingginya tingkat risiko wisata di Kawasan Wisata Pantai Pangandaran adalah jumlah personil lifeguard dan rambu-rambu peringatan yang tidak mencukupi. Pangandaran Beach is one of the coastal tourism objects located in Pangandaran Regency, West Java Province and it is one of the leading tourism object in West Java Province. Tourism in Pangandaran has beach-physical potential hazard and some case of it creating casualties. This research aims to identify the potential physical hazards of the beach for the safety of visitors, assess the risk level of beach-physical potential hazard for the safety of visitors, and determine the cause of the high number of tourism risk in the Pangandaran Beach Tourism Area. The method used in this research is the assessment method. The data used in the assessment of the level of beach risk are: number of visitors, number of lifeguards, beach length, number of signages, lifejacket usage, tourist accident, beach type, and wave height. Research results show that Pangandaran Beach Tourism Area belonged to longshore bar and trough beach type. Pangandaran Beach Tourism Area is belonged to multiple fatalities category with an R value (risk level) more than 200 on all beaches either on low season or high season. At high season period on West Beach the category shift to fatal. There is a significant difference in R value between two periods. The difference in value of R shows that Pangandaran Beach Tourism Area is relatively safer during the high season period.

A randomized double blind clinical trial was conducted to study the effects of iron supplementation on hemoglobin values of 97 iron-deficient anemic (DA) and iron-sufficient (IS) infants, 12 to 18 months of age. IDA (n=SO) infants were assigned randomly to either receive dietary ferrous sulfate or placebo for 4 months. Similar treatment randomization was done among IS (n=4 7) infants. Before intervention, the mean hemoglobin value of the IDA infants was significantly (p<0.01) lower than that of the IS group. After intervention, there was an increase in the hemoglobin values of the IDA infants who had received iron, and was significantly (p<0.01) higher than those of the placebo treated IDA group, lS group, as well as placebo treated IS group. Hemoglobin values of the IDA infants who had received iron, increased up to the normal level as refer to the WHO's criteria used for normal hemoglobin values.

Pengelolaan sumberdaya alam dan lingkungan berbasis masyarakat, di berbagai tempat di dunia, dalam skala tertentu dan di tengah keterbatasan negara, telah banyak disebutkan sebagai satu bentuk pengelolaan yang mampu menjamin keberlanjutan sumberdaya alam dan lingkungan yang dikelola. Sejalan dengan gagasan tersebut, artikel ini menguraikan hasil kajian tentang salah satu sistem pengelolaan berbasis masyarakat dalam pengelolaan sumberdaya perikanan (teripang) pada salah satu komunitas warga yang berada di kawasan pesisir utara Papua yang disebut dengan Egek. Penelitian ini menggunakan metode kualitatif dan kuantitatif. Metode kualitatif digunakan untuk mendeskripsikan sistem egek yang dipraktikkan secara kolektif oleh warga masyarakat dalam pengelolaan sumberdaya perikanan. Selain itu, studi ini juga megumpulkan data perikanan teripang yaitu (1) Distribusi Ukuran Panjang, (2) Kepadatan Populasi dan (3) Keanekaragaman jenis dengan menggunakan metode kuantitatif untuk mengetahui kondisi sumberdaya teripang yang dikelola oleh masyarakat. Hasil penelitian memperlihatkan bahwa sistem pengelolaan sumberdaya perikanan berbasis masyarakat di Kampung Malaumkarta telah memenuhi unsur pengelolaan yang baik dimana telah terdapat batasan wilayah pengelolaan, sistem aturan dan sanksi, hak pemanfaatan, sistem monitoring dan otoritas kelembagaan. Hal ini tentu berdampak positif terhadap kelestarian sumberdaya perikanan teripang yang merupakan salah satu objek biota egek dimana nilai keanekaragamannya masuk dalam kategori sedang yaitu 1,48 dengan kepadatan populasi masuk kategori baik yaitu 223,2 ind/ha dengan sebaran ukuran individu teripang didominasi pada ukuran dewasa yang sudah layak untuk dipanen yaitu ukuran >30 cm mencapai 68%.Community-based natural resource management, in various places in the world, on a certain scale and in the midst of state limitations, has been widely mentioned as a form of management that is able to ensure the sustainability of the natural resources and the environment being managed. In line with this idea, this article describes the results of a study on a community-based management system in the management of fishery resources (sea cucumbers) in a community of residents in the northern coastal area of Papua called “Egek”. This research uses qualitative and quantitative methods. Qualitative methods are used to describe the egek system that is practiced collectively by community members in the management of fishery resources. In addition, this study also collects data on sea cucumber fisheries, namely (1) Length Size Distribution, (2) Population Density and (3) Species diversity using quantitative methods to determine the condition of sea cucumber resources managed by the community. The results of the study show that, the community-based fisheries resources management system in Malaumkarta village has fulfilled the elements of good management where there are management boundaries, a system of rules and sanctions, utilization rights, monitoring systems and institutional authorities. This certainly has a positive impact on the sustainability of sea cucumber fisheries resources which is one of the objects of “Egek” where the diversity value is in the moderate category, namely 1.48 with a population density in the good category of 223.2 ind/ha with the distribution of individual sea cucumbers being dominated by adult size that are already good for harvesting, i.e. > 30 cm in size reach 68%.
