Abstract

The concentrations and the distribution of organotin (OT) compounds and booster biocides in sediment and biological samples from Indonesia, Malaysia, Thailand and Vietnam are reviewed. Basically, the concentrations of tributyltin (TBT) in these countries were within the levels that have been reported in developed countries. However, the concentrations of triphenyltin (TPT) and booster biocides were lower than the reported values. Concerning the spatial distribution of antifouling biocides, higher concentrations of OTs were detected in the industrial area and fishing ports. Among ASEAN countries, the highest concentrations of TBT and TPT were observed in Bitung, Indonesia, where many ships from Southeast Asia visit and is moored in the port. The ratio of detected alternative biocide differed from country to country. Especially, many booster biocides were detected and their concentrations were high in Vietnam.

Abstract

Southeast Asia is known as a center of biodiversity of the earth. As economic growth of this region is remarkable, conservation of biodiversity is a top priority issue. For this purpose, it is important to monitor the environmental condition in effective ways. We are trying to detect pollutants in coastal and estuary waters through the expression level of pollutant-responsive genes of rice fishes of the genus Oryzias, widely distributed in Asia. Japanese medaka O. latipes is a useful model because whole genome sequence is available. Javanese medaka O. javanicus and Indian medaka O. dancena, both of which are widely distributed in Southeast Asia and adaptable to seawater, are also potential models. One possible method for pollution monitoring is the use of transgenic fish bearing artificialgene construct containing the pollutant-responsive promoter and a reporter gene. For example, transgenic strains that can detect estrogen-like substances have already been established. It is also probable to detect pollutants by quantifying mRNA or proteins expressed from the pollutant-responsive gene. In any case, the most important point is to identify the gene that responds to specific pollutants. Comprehensive transcriptomic analyses are powerful tool for this purpose. Organotin-responsive genes are being screened at present.

Abstract

Tujuan dari penelitian ini antara lain adalah menganalisis struktur pasar nilam dan menganalisis perilaku pasar nilam di Desa Kalimanis, Kecamatan Doko, Kabupaten Blitar. Hasil dari penelitian ini menunjukkan bahwa (1) Struktur pasar yang terjadi pada nilam di Desa Kalimanis, Kecamatan Doko, Kabupaten Blitar termasuk dalam pasar Oligopsoni. Struktur ini dicirikan dengan jumlah petani banyak tetapi pedagang sedikit, pedagang tersebut terdiri dari pedagang perantara yang hanya ada dua responden saja yaitu Kelompok Tani dan Koperasi Ngudi Luhur, produk yang dijual sejenis dan tidak terdapat diferensiasi produk dan petani berperan sebagai price taker, akan tetapi harga yang ditentukan oleh masing-masing pedagang sesuai dengan harga yang ada di pasar, sehingga hal demikian petani tidak sampai banyak dirugikan dan harga yang ditentukan tersebut telah disepakati bersama antara pedagang dengan petani. Hal ini juga terlihat dari Indeks Herfindahl pedagang perantara sebesar 0,568. Disamping itu struktur pasar oligopsoni juga terlihat dari nilai Indeks Rosenbluth pada pedagang perantara sebesar 0,613. Disisi lain pedagang mengalami hambatan karena diperlukan modal yang besar dan jaringan pemasaran yang luas. (2) Perilaku pasar menunjukkan bahwa petani berperan sebagai price taker karena memiliki posisi tawar yang lemah. Penetapan harga nilam didominasi oleh lembaga pemasaran, dan informasi pasar juga didominasi oleh lembaga pemasaran, akan tetapi lembaga pemasaran tidak melakukan kolusi dan taktik, karena harga yang ditetapkan oleh lembaga pemasaran sesuai dengan harga yang ada di pasar. Di dalam saluran pemasaran terdapat dua jenis saluran, yang dimana setiap saluran pemasaran tersebut telah melakukan fungsi-fungsi pemasaran dengan baik. Kata Kunci: Stuktur dan Perilaku Pasar Nilam

Abstract

The concentrations of Cd, Cu, Pb, Zn, Ni and Fe were determined in the marine gastropod Nerita lineata collected on May 2005 from the intertidal zone of fourteen stations in Dumai, Indonesia (mean length 21.43 – 24.04 mm) and ten stations in Johor, Peninsular Malaysia (mean length 22.61 – 26.60 mm). The results of the present study showed that metal concentrations in the shell, operculum and soft tissue of N. lineata varied at different sampling stations. The mean concentrations of Cd, Cu, Pb, Zn, Ni and Fe in the samples collected from Dumai were 4.14; 5.90; 44.43; 3.74; 20.73; 24.91 μg/g in shell; 4.16; 7.31; 51.78; 17.63; 23.52; 30.60 μg/g in operculum and 0.71; 15.16; 9.34; 94.69; 5.08; 397.96 μg/g dry weight in the total soft tissue; whilst those collected from Johor were 4.18; 5.06; 59.84; 4.8122; 19.29; 31.60 μg/g in shell; 4.73; 6.51; 60.57; 19.48; 20.68; 34.92 μg/g in operculum and 1.24; 18.02; 19.75; 95.09; 5.57; 473.56 μg/g dry weight in the total soft tissue, respectively. Samples of N. lineata from both Dumai and Johor tend to show similar trend in metal accumulation in which the concentrations of Cd, Pb and Ni decreased in the order: operculum > shell > soft tissue whilst Cu, Zn and Fe in the order of soft tissue > operculum > shell. In general, samples from Johor accumulated higher heavy metal concentrations when compared to samples from Dumai, except for Cu and Ni in the shell and operculum, which exhibited vice versa situation. Higher concentrations of metals were recorded in samples collected from the stations close to the industrial and anthropogenic activities. However, most of the concentrations were still comparable to the previous reported studies from other geographical areas.

Abstract

Heavy metal concentrations in sediment collected from Dumai coastal waters have been studied by using sequential extraction technique to determine the distribution and geochemical speciation (EFLE, acid reducible, oxidisable organic and resistant) of Cd, Cu and Ni. The results showed that the highest concentrations of total Cd was in Cargo Port area and the lowest in Penyembal, whilst for Cu and Ni the highest concentrations were in Ferry Port and the lowest in Batu Panjang.  The total concentrations of Cd, Cu and Ni ranged from 0.65 – 1.82, 1.84 – 13.16 and 7.68 – 17.98 µg/g dry weight, respectively. Higher metal concentrations were detected in the eastern and central parts of Dumai city center where most of anthropogenic activities are concentrated. However, most of the concentrations of Cd, Cu and Ni were still below the ERL and ERM values. Only at few stations, especially in the eastern and central parts of Dumai, showed Cd concentrations exceed the ERL but still well below the ERM values. Metal concentrations in 78.26% (Cd) and 91.30% (Cu and Ni) of the sampling stations were dominated by resistant fraction indicating natural origin of these metals. Non resistant fractions, however, were found higher than resistant fractions at Pelintung, Pertamina, Cargo Port, Penyembal and Batu Panjang for Cd; Penyembal and Batu Panjang for Cu and Pelintung and Guntung for Ni. These findings indicated that anthropogenic inputs of Cd, Cu and Ni occurred in these stations. For all sampling site groups, Cd, Cu and Ni were mostly accumulated in the resistant fraction (55.28 – 58.31%; 65.02 – 91.84% and 50.08 – 66.88% of the total concentrations respectively) which indicated that the mobility and anthropogenic inputs of these metals in Dumai coastal waters were quite low.

Abstract

This article intends to identify and to describe the unique structure and the managing style that owns primordial characteristics, that is giving significance to kinship, religion, and local Bugis cultural values, which made up the cultural system of PT. Hadji Kalla family business. Theoritically, this research was inspired from Weberian perspective on the ideal types of bureaucracy, that observes organizations (in this case is the family business) as one of the socio-cultural phenomena which is neutral and value-free, that is place aside its subjective aspects. The research was conducted in two locations, the head office and one of the branch offices using qualitative approach that relies on participant observation, in-depth interviews, and literature studies. The results of the research shows that the family business of PT. Hadji Kalla that has advanced into national level still prioritizes kinship, ethnicity, and religious aspects in the daily activities of the company. The value even take parts in providing the company’s colour to the urban societies in various districts where the company stands. This means that although the society has undergone transformations, it doesn’t mean that the primordial value, and the elements that exist outside of businesses (such as kinship, big men, religion, cultural values, and interest) do not influence the activities that are held in formal organizations. Therefore, the interventions of subjective aspects will always appear, followed with the application of the modern management system that is implemented by PT. Hadji Kalla company.
