"Indonesia merupakan kepulauan dengan jutaan nelayan, namun belum banyak penelitian mengenai penyakit dekompresi (PD). Tujuan penelitian ialah mengidentifikasi prevalensi dan beberapa faktor dominan yang berkaitan dengan kenaikan risiko PD setelah penyelaman. Penelitian dilakukan antara Oktober ? November 2007 pada seluruh nelayan peselam Moroami di Kepulauan Seribu Jakarta. Anamnesis dan pemeriksaan dilakuan sebelum dan tiga kali setelah menyelam. Subjek menderita PD jika mengalami salah satu gejala: nyeri sendi, nyeri otot, atau gatal-gatal, lemah tungkai, gangguan buang air besar (obstipasi, melena, diare) atau kecil, pendengaran, penglihayan, sakit kepala, vertigo, sesak napas, nyeri dada, kejang, pingsan, mual, muntah (biasa atau darah). Dari 123 subjek yang potensial, 5 subjek sedang menderita penyakit pernafasan atas, sehingga sebanyak 117 berpartispasi dalam penelitian ini. Sebanyak 62 orang (53%) menderita PD. Model akhir menunjukkan bahwa mouthpice, valsava bila telinga sakit, peselam perlu kursus menyelam untuk menghindari kecelakaan, dan kecepatan naik merupakan faktor-faktor dominan yang berkaitan dengan PD. Kecepatan naik merupakan faktor risiko yang tertinggi. Peselam yang naik 18 meter per menit atau lebih dibandingkan dengan yang naik kurang dari 18 m per menit mempunyai risiko dua kali lipat menderita PD [risiko relatif suaian (RRa) = 2.2; 95% interval kepercayaan (CI) = 1,11 ? 3,56]. Di samping itu peselam yang menderita dibandingkan dengan yang tidak PD sebelum menyelam mempunyai risiko 20% lebih banyak (95% CI = 0,86-1,68; p = 0,285). Di samping penggunaan mouthpice yang baik, cara valsava yang benar, para nelayan tradisional terutama perlu diberikan latihan supaya naik ke permukaan laut kurang dari 18 m per menit untuk mengururangi risiko PD.

AbstractIndonesia is an archipelago with many traditional divers, however research on decompression sickness (DCS) has not yet elaborated. The aim of the study was to identify the prevalence of DCS and factors related to it. The study was conducted on October-November 2007 among fisherman moroami divers in Seribu Island Jakarta. Anamnesis and physical examination was taken before and three times after diving. Subject was diagnosed as having DCS if experienced one of these symptom or sign: myalgia, muscle pain, skin rash, ankle weakness, bowel movement & bladder dysfunction, visual disturbances, headache, vertigo, dyspnoe, chest pain, convulsion, unconsciousness, nausea and vomiting. Among 123 potential divers, five were having upper respiratory infection, so only 117 divers participated in this study. Final model analysis showed that regulator, valsava when having ear pain, ascending speed to surface, and lack of training were risk factors to obtain DCS. Divers whose ascending speed more than 9 m per minutes had two times risk to get DCS [adjusted ratio = 2.2; 95% confidence interval (CI)= 1.11 ? 3.56]. Having DCS before diving, increased risk 20% (RRa = 1.20; 95% CI = 0.86-1.68; P=0,285). Beside knowledge to use regulator correctly and valsava, fisherman Moroami divers need to be trained to ascend speed to sea level surface less than 9 m per minute. "

"ABSTRAKRuang lingkup dan cara penelitian:Penyakit dekompresi adalah suatu kecelakaan yang timbul akibat penurunan tekanan lingkungan yang mendadak. Penelitian ini mengevaluasi insidens kecelakaan dekompresi pada 56 peselam alam yang memakai kompresor konvensional di kelurahan P. Panggang dan hubungannya dengan beberapa faktor resiko. Data sosiodemografis, riwayat pekerjaan dan riwayat penyakit didapat melalui anamnesis menggunakan kuesioner, sedangkan status kesehatan ditetapkan dengan anarnnesis, pemeriksaan fisik dan neurrologis. Uji Kai kuadrat digunakan untuk menilai hubungan antara faktor resiko dengan penyakit dekompresi, sedangkan analisis regresi logistik dipakai untuk melihat probabilitas timbulnya penyakit dekompresi sehubungan faktor resiko yang ada.Hasil dan Kesimpulan :insidens penyakit dekompresi pada penulisan ini 51,8 % dengan tipe I terbanyak ditemukan (79,3 %). Persentase yang tinggi ini dihubungkan dengan pengetahuan prosedur penyelaman yang 100 % buruk. Tidak ditemukan hubungan antara kedalaman, lama selam, kecepatan naik ke permukaan, umur, masa kerja, pendidikan, BMI dan minum alkohol dengan terjadinya penyakit dekompresi. Faktor resiko utama penyakit dekompresi yang ditemukan adalah frekuensi penyelaman (OR 12,5) dan meningkatnya kadar CO2 (OR 5,6).

ABSTRACT

A Study of the Incidence of Decompression Accidents: Analysis of the Risk Factors Contributing to Decompression Sickness among Divers Using Conventional Compressors at Panggang Island - Village level Administration Area.

Scope and Research Method:

Decompression sickness is one of the accidental outcomes resulting from a sudden decrease in ambient pressure. The study evaluates the prevalence of decompression accidents among 56 divers using traditional methods and conventional compression in the village-level administrative area of Panggang Island. The study also explores the significance of some of the risk factors in the incidence of decompression sickness. Social-demographic data, divers' work history, and the history of divers' illnesses were obtained through interviews based on responses to a questionnaire. Also, the divers' current health condition was determined by interview and by physical and neurological examination. The Chi-square test method was employed to assess the relationship between risk factors and decompression sickness, while logistic regression analysis was used to determine the probability of occurrence of decompression sickness with respect to existing risk factors.

Results and conclusions :

The incidence of decompression sickness in this study was 5L8 %, with type I decompression sickness (79.3%) constituting the most prevalent sickness observed. This high percentage can be linked to an extremely poor knowledge of diving procedures among the divers. It was not possible in the study to determine the relationship between the incidence of decompression sickness and depth of dive, duration of dive, rate of ascent to the surface, the age of the diver, the length of diving experience, education, BMI, or alcohol consumption. The main factors in the incidence of decompression sickness were found to be frequency of dive activities (OR 12.5) and an increase in the concentration of COz (OR 5.6)."

"Sertifikasi SCUBA diving tidak hanya diminati oleh orang-orang yang memiliki penghasilan tetap. Produk yang tidak menjadi kebutuhan pokok ini juga diminati oleh mahasiswa yang pada umumnya belum memiliki penghasilan tetap. Oleh karena itu, ada perilaku konsumen tertentu yang mendasarinya. Skripsi ini bertujuan untuk menganalisis perilaku konsumen sertifikasi SCUBA diving di kalangan mahasiswa menggunakan pemetaan persepsi. Perilaku konsumen diinterpretasikan ke dalam atribut-atribut tertentu. Kemudian atribut-atribut terpilih dibuat menjadi sebuah peta persepsi.

ABSTRACTThis research is determined to understand fishermens information needs at Muara Kaliadem, North Jakarta. Research approach that is used in this research is qualitative descriptive method. The data is collected by using structured interview and supported documents to strengthen the analysis in the discussion. Research model that is used in this research is Johnsons information needs fulfillment factors. The result of this research shows fishermens information needs and identifies factors that trigger them to do information seeking to fulfill their information needs. Factors such as their personal background and as an individual become their triggers in information seeking. Barriers found when they do information seeking are coming from themselves as an individual regarding their own limitations, also access to information that is hard to reach. There are some suggestions regarding overcoming these barriers such as providing access to information resources at certain points and socializing about information resources routinely."

"This book offers a survey of the state of the art in the field of motion sickness. It begins by describing the historical background and the current definition of motion sickness, then discusses the prevalence among individuals, along with the physiological and psychological concomitants of the disorder. It reviews the incidence of motion sickness in numerous provocative motion environments and discusses various personal factors that appear to influence this aspect. Various characteristics of provocative motion stimuli are also described, together with the results of studies conducted in the laboratory, on motion simulators and at sea. Laboratory tests that could potentially be used to assess an individuals susceptibility to motion sickness and his or her ability to adapt to motion environments are presented in detail, together with the ways in which individuals might be trained to prevent motion sickness or more effectively cope with motion environments. In closing, the book reports on the cognitive-behavioral approach developed by the author (Dobie, 1963) as well as the various desensitization programs employed in military settings, and discusses the relative effectiveness of these methods in comparison to cognitive-behavioral counseling."
