Abstract

AbstrakBising impulsif berlebihan mengakibatkan kerusakan mekanik maupun metabolik (stres oksidatif) pada struktur telinga dalam (koklea), sehingga terjadi trauma akustik (TA). Stres oksidatif yang disebabkan peningkatan radikal bebas ROS/RNS di dalam organ Korti, mengakibatkan apoptosis serta nekrosis sel-sel rambut koklea. Stres oksidatif ditandai oleh peningkatan malondialdehid (MDA), penurunan enzim glutation peroksidase (GPx), dan hasil emisi otoakustik abnormal (refer), Mekanisme pertahanan tubuh terhadap stres oksidatif dilakukan oleh enzim anti oksidan endogen (Superoksid dismutase/SOD, katalase/CAT dan GPx). Mekanisme kerja seluler  glutation peroksidase mimetik sama dengan GPx. Penelitian bertujuan untuk mengetahui pengaruh glutation peroksidase mimetik terhadap kadar glutation peroksidase dan malondialdehid darah serta nilai emisi akustik pada prajurit dengan risiko TA akibat ledakan meriam Howitzer 105. Rancangan penelitian adalah clinical trial pre and post design, randomized, double blind and placebo controllel, yang dilakukan pada 34 orang prajurit siswa Tamtama baru Pusdik Armed saat latihan menembak meriam Howitzer 105 pada tanggal 7-10 Juli 2014 di Cimahi dan Batujajar. Subjek penelitian dibagi dua, yakni kelompok perlakuan dan kontrol. Kelompok perlakuan diberi glutation peroksidase mimetik (Ebselen SPI 1005) 1x200 mg peroral saat latihan, sedangkan kelompok kontrol diberi plasebo. Kedua kelompok diukur kadar MDA dan GPx darah serta hasil audiometri nada murni dan nilai emisi otoakustik (DPOAEs) sebelum dan setelah latihan menembak. Data dianalisis menggunakan uji parametrik dan non parametrik, dan besarnya manfaat perlakuan dihitung menggunakan Number Needed to Treat (NNT, 95%CI). Kemaknaan hasil ditentukan berdasarkan nilai p < 0,05. Hasil penelitian menunjukkan kejadian TA menggunakan pemeriksaan audiometri nada murni pada kelompok kontrol sebanyak 23,5%, dan pada kelompok perlakuan sebanyak 0%, sedangkan menggunakan pemeriksaan DPOAEs pada kelompok kontrol sebanyak 47,1% abnormal/refer dan pada kelompok perlakuan 100% normal/pass, dan perbedaan ini secara statistik bermakna  (p<0,05).Pemberian Ebselen SPI 1005 pada kelompok perlakuan meningkatkan 82,4% kadar GPx eritrosit (NNT, 95%CI=1,889 [1,1593,016]; p=0,004), meningkatkan 88,2% kadar GPx plasma (NNT, 95%CI=1,417 [0,970-1,775]; p<0,001), menurunkan 100% kadar MDA eritrosit (NNT, 95%CI = 1,417 [0,994-1,836]; p<0,001), dan menurunkan 94,1% kadar MDA plasma (NNT, 95%CI=2,125 [1,29-3,904]; p=0,01), serta menghasilkan 100% nilai DPOAEs normal/pass (NNT, 95%CI = 2,125 [1,335-3,987]; p=0,01). Penelitian ini menyimpulkan bahwa pemberian Ebselen SPI 1005 pada prajurit dengan risiko trauma akustik selama pelaksanakan latihan menembak meriam Howitzer 105, meningkatkan kadar GPx darah, menurunkan kadar MDA darah, dan menghasilkan nilai DPOAEs normal/pass. Kata kunci : Ebselen, Emisi otoakustik, GPx, MDA,Trauma akustik.AbstractExcessive noise exposure may cause mechanical and metabolic (oxidative stress) to the inner ear structure (cochlea), resulting in acoustic trauma (TA). Oxidative stress which caused by increasing of free radical ROS/RNS in the organs of Corti, causing apoptosis and necrosis of cochlear hair cell. Oxidative stress was characterized by increasing of malondialdehyde (MDA), decreasing of glutathione peroxidase (GPx) enzyme, and abnormal otoacoustic emission value (refer). Defense mechanism toward oxidative stress was mediated by endogenous antioxidant enyzme (superoxide dismutase/SOD, catalase/CAT, and GPx). Cellular mechanism of glutation peroxidase mimetic was similar as Gpx. Aim of this study was to determine the impact of glutathione peroxidase mimetic to glutathione peroxidase and malondialdehyde level in blood, also otoacoustic emission value on soldiers with risk of TA due to explosion of Howitzer 105 artillery weapon. The design of this study was clinical trial pre and post design, randomized, double blind and placebo controlled, on 34 new recruit soldiers in Artillery Academy of Indonesian Army, during the soldiers were trained to firing Howitzer 105 artillery weapon, from 7th-10th July 2014 in Cimahi and Batujajar. Subjects were divided into 2 groups, the exposure group (group given treatment) and control group. Exposure group was given glutathione peroxidase mimetic (Ebselen SPI 1005) 200mg, orally once daily during the training, meanwhile control group was given. Malondialdehyde and Glutathione Peroxidase level in blood, pure tone audiometry and otoacoustic emission value (DPOAEs) was measured from those two groups, before and after firing training. The data was analyzed using parametric and non parametric, with Number Needed to Treat (NNT, 95%CI) and significance value (p<0.05). The results of this study showed the number of acoustic trauma events in controle group based on pure tone audiometry test was 23.5%, exposure group was 0%, and based on DPOAEs test the controle group showed 47.1% abnormal/refer, exposure group showed 100% normally/pass, and this difference stastically significance (p<0.051). The group which was given Ebselen SPI 1005 showed increasing 82.4% erythrocyte GPx level (NNT, 95%CI=1.889 [1.159-3.016]; p=0.004), showed increasing 88.2% plasma GPx level (NNT, 95%CI=1.417 [0.9701.775]; p<0.001), decreasing 100% erythrocyte MDA level (NNT, 95%CI = 2.125 [1.335-3.987]; p=0.01), showed decreasing 94.1% plasma MDA level (NNT, 95%CI=2.125 [1.29-3.904]; p=0.01), and resulting 100% in normal/pass DPOAEs value (NNT, 95%CI = 2.125 [1.335-3.987]; p=0.01). This study concluded that giving Ebselen SPI 1005 to soldiers with risk of acoustic trauma during the firing Howitzer 105 artillery weapon, increasing GPx level in blood, decreasing MDA level in blood, and resulting normally DPOAEs value ( pass )Keywords : Acoustic trauma, Ebselen, GPx, MDA, Otoacoustic emission

Abstract

AbstrakKesenjangan antara produksi dan kebutuhan domestik daging sapi saat ini telah mengakibatkan kecenderungan tingginya harga daging sapi nasional. Tingginya harga daging di pasar tersebut tidak dapat dinikmati oleh peternak antara lain karena posisi tawar peternaknya lemah. Salah satu model pengembangan yang untuk mengatasi masalah tersebut telah diinisiasi oleh Bank Indonesia adalah klaster. Pemasaran ternak sapi dalam manajemen kelompok bakal klaster melibatkan banyak pelaku yang saling terkait sehingga masalahnya menjadi kompleks dan dinamis. Pendekatan yang tepat untuk memahami persoalan adalah dinamika sistem. Hasil penelitian menunjukan bahwa sistem pemasaran yang dilakukan dalam manejemen kelompok bakal klaster saat ini masih menempatkan peternak anggota kelompok dalam posisi tawar yang lemah. Peternak anggota hanya menerima harga dari pedagang pengumpul, pedagang pengumpul menerima harga dari koordinator pedagang pengumpul, dan koordinator pedagang pengumpul mendapatkan harga dari pedagang besar. Artinya harga di peternak anggota sangat  tergantung dari harga di pedagang besar. Kebijakan yang diusulkan untuk meningkatkan posisi tawar peternak adalah menerapkan harga pedagang pengumpul dan koordinator pedagang pengumpul di peternak. Hal ini dapat dilakukan apabila ada inovasi  kelembagaan usaha bersama simpan pinjam menjadi koperasi serta merangkul semua pedagang. Cara lainnya adalah dengan membentuk unit balai lelang agro di koperasi. Koperasi berfungsi menampung produksi anggota dan melelangnya kepada pedagang. Hasil simulasi menunjukkan bahwa skenario kebijakan menerapkan harga di tingkat pedagang akan meningkatkan keuntungan dan likuiditas keuangan peternak.Kata Kunci: Sapi Bali, posisi tawar, klaster, dinamika sistem, koperasiAbstractThe gap between production and domestic consumption of beef has now resulted in a tendency to high beef prices nationwide. The high price of meat in the market can not be enjoyed by farmers, among others, because of the weak bargaining position of the farmer. One of the development model to overcome these problems have been initiated by Bank Indonesia is a cluster.  Marketing of cattle in the cluster group management will involve many actors are interrelated so that the problem becomes complex and dynamic. The right approach to understanding the problem is the system dynamics. The results showed that the  marketing system are carried out in the management group will cluster is still putting breeders group members in a weak bargaining position. Breeders members only receive the price of the traders, traders receive price from collectors coordinator, and the coordinator of traders get the price of large traders. Means the price at farmer members highly dependent on the price at wholesalers. The proposed policy to improve the bargaining position of farmers is to apply the price collectors and traders in  breeder coordinator. This can be done if there is a joint effort of institutional innovation become savings and loan cooperatives and embrace all traders. Another way is to form a unit in the cooperative agro auction. Cooperative serves to accommodate the  production of the members and auction to the merchant. The simulation results show that the policy scenarios apply price at the merchant level will improve profitability and financial liquidity breeders.Keywords: Bali Cattle, bargaining position, cluster, system dynamics, cooperative

Abstract

AbstractIn the Koto Panjang Dam, Riau there are more than 1582fish floating cages present.  Fish feed spilled from the cage is believed to affect the diet of wild endemic fishes inhabit the dam. To understand the effect of the cage on the diet of the endemic, a study has been conducted on May to September 2013. There were 5 sampling sites, 2 sites located in the natural area that there is no cage (St 1Na and St2 Na) and the others (3 Ka, 4 Ka and 5 Ka) were in the area around the cage. Fishes were sampled hourly, for a 24 hour period and their stomach content was analyzed. Results shown that there were 31 species of endemic fishes such as Puntius schwanenfeldii, Macrones nemurus, Hampala bimaculata, Osteochillus hasselti, Rasbora vaillanti, Tynnichtys vaillanti, Ophiocephalus melanosoma, Chela oxygastroides, Cyclocheilichthys heteronema, Notopterus chilata, Puntius bramoidesandCyclocheilichtys apogon. Among these fishes, however, only P. schwanenfeldii that greatly affected by the presence of the aquaculture activities as the stomach of fish living around the cage was filled with fish feed pellets (more than 90%). The fish living in the area with no cage, however, filled with animal and plant remains. This fact indicates that the P.  schwanenfeldii is an opportunist fish that is able to change their diet into fish feed pellets. Based on data obtained, it can be concluded that the presence of fish floating cage aquaculture activities affect certain fish species only.Key words: Fish floating cage, Puntius schwanenfeldii, Koto Panjang Dam, endemic fish, fish feed pellet

Abstract

AbstractInformation of genetic variability and heritability of sorghum stem are very important for lodging-tolerant breeding program. Genotypic correlation of stem morphological character to lodging tolerance is very useful in selection program. The objectives of this experiment were to observe variability and heritability of stem character and to determine stem character that correlate with lodging tolerance. Field experiment was carried out in experimental station of Agriculture Faculty Universitas Padjadjaran. The results showed that all stem characters showed wide genetic variability except stem density and stem diameter. Low and medium heritability were showed also by stem density and stem diameter. Other stem characters showed high estimation of heritability value. Stem elasticity and number of inter-node showed negative correlation to oblique angles of stem. Other stem characters had no correlation with lodging tolerance.Keywords: genotypic correlation, heritability, lodging, sorghum, variability
