Periphytic diatom (Bacillariophyceae) is diatom that lives attach on a substrate and it was dependent on the environmental conditions in an aquatic ecosystem. This study was aimed to determine the composition of periphytic diatom (Bacillariphyceae) on glass substrate and the condition of physical chemical water in Kapuas Kecil River. This study was conducted from September to December 2017. The sampling stations were chosen by purposive random sampling method and divided into four stations. At each station in the river were installed 5 baskets each with 5 glass slides. Samples were collected from three baskets with sampling intervals on day 2, 5, 10, 15, and 20. The result shows that the composition of periphytic diatoms (Bacillariophyceae) in Kapuas Kecil River consists of 29 genera from 2 orders (Pennales and Centrales) and 12 families. The most commonly genera found of periphytic diatom were Eunotia, Gomphonema, Frustulia and Nitzschia.

Periphytic Diatom

The investigation in this paper aimed to describe periphytic diatom assemblage, species composition and distribution in tropical polluted Linggi (sensu stricto or s.s.) and Kundor rivers in  Negeri Sembilan, Malaysia.  Regardless of ecological and environmental conditions, diatoms were the numerically dominant flora among periphytic  algae  collected monthly over a period of 13 months at nine stations in the Linggi (s.s.) and Kundor rivers.  The freshwater periphytic diatom samples were collected mainly using artificial substrates and supplemented with natural substrates.  The periphytic diatoms thus collected from both natural and artificial substrates comprised 86 taxa (82 pennate and 4 centric forms) belonging to 21 genera. Of the 86 species, 71 species were found colonized in artificial substrates while the remaining 15 species were recorded exclusively on natural substrates. On the whole, the most common diatoms in both rivers combined were Eunotia vanheurckii, Gomphonema parvulum, Nitzschia palea, Pinnularia braunii, Navicula cryptocephala, Achnanthes saxonica, Achnanthes minutissima and Pinnularia microstauron.  The most abundant species were E. vanheurckii, N. palea, A. saxonica, G. parvulum and A. minutissima.

ABSTRAK Perairan estuari Banjir Kanal Timur berfungsi sebagai daerah asuhan bagi larva ikan. Daerah estuari bersifat fluktuatif sehingga sifat-sifat fisik, kimia dan biologi bervariasi, pada fase larva ikan sangat menentukan kelangsungan hidup dari spesies ikan maupun populasi. Oleh karena itu, mengetahui keberadaan larva ikan ekonomis penting dapat memberi informasi tentang daerah mana yang dapat digunakan sebagai daerah penangkapan dan daerah mana yang harus dilestarikan. Penelitian dilakukan pada bulan Maret-April 2016 di Muara Banjir Kanal Timur Kota Semarang  yang bertujuan untuk mengetahui komposisi dan distribusi spasial larva ikan. Metode yang digunakan yaitu metode Purposive Random Sampling. Hasil penelitian menunjukan jumlah rata-rata larva ikan sebanyak 1851 ind/150m3 terdiri dari famili Apogonidae, Mugilidae, Gerreidae, Lutjanidae, Engraulidae, Nemipteridae, Ambassidae, Gobiidae dan Chanidae. Jenis larva ikan yang yang paling banyak ditemukan adalah Mugillidae (Belanak) 38,92%, sedangkan yang paling sedikit adalah Chanidae (Bandeng) 0,38%.  Larva ikan paling banyak tertangkap di daerah pantai (Titik III) dan yang paling sedikit tertangkap didaerah muara menuju sungai (Titik VI). Perhitungan indeks morista menunjukan larva ikan menyebar secara acak. Struktur komunitas larva ikan yaitu indeks keanekaragaman (H’) berkisar 0,64-1,66, indeks keseragaman (E) berkisar 0,14-0,39, dan indeks dominasi berkisar 0,21-0,67. Berdasarkan hasil uji regresi menunjukkan antara salinitas dengan kelimpahan larva ikan berkorelasi positif, sedangkan kecepatan arus dengan kelimpahan larva ikan berkorelasi negatif. Kata Kunci: Estuari; Larva Ikan; Komposisi; Distribusi; Banjir Kanal Timur Semarang.  ABSTRACT The estuaries of eastern Banjir Kanal served as the nursery ground for fish larvae. Areas of estuaries were fluctuating. So the parameters of the physical, chemical and biological were variation, in fish larvae phas  largely determine  survival rate of fish species or populations. For it to, knowing the existence of economically important fish larvae could providing information about which areas be using as a capture area and which areas that should be preserved. Research conducted in March-April 2016 at the Eastern Banjir Kanal of Semarang, aims to find out the composition and spatial distribution of fish larvae. The method used Purposive Random Sampling method. The research showed the range number of larvae as 1851 ind/150m3 consists of Familia Apogonidae, Mugilidae, Gerreidae, Lutjanidae, Engraulidae, Gobiidae, Ambassidae, Nemipteridae and Chanidae. Types of fish larvae found the most high was Mugillidae (Mullet) 38,92%, while the least was Chanidae (Milkfish) 0,38%. The larvae of most fish caught in coastal areas (point III) and the least caught in the estuary towards the river (Point VI). The calculation of the index morista fish larvae spread randomly. Fish larvae community structures were the index of diversity (H ') range from 0,64-1,66, uniformity index (E) range 0,14-0,39, and dominance index range from 0,21-0,67. Based on the results of the regression analysis showed between salinity with an abundance of fish larvae correlating positively, where the current speed with an abundance of fish larvae  correlating negatively.Keywords: Estuarie;  Fish Larvae; Composition; Distribution; Eastern Banjir Kanal Semarang.

This study mainly focuses on customer care management and customer loyalty. Even though there are many experiential studies about customer care management and customer loyalty system, the lack of studies on customers in Karabük and Safranbolu locally, has leaded to focus on this study. Thus, this study mainly focuses on the influence of customer care treatments of banks in Karabük and Safranbolu on customer loyalty. Descriptive research type was used in the study. In this study simple random sampling method was used which is one of the probability sampling method, face to face surwey to all 726 participants was used for the study. As the result of the experiential study, the attendance and influence of customer care management and loyalty systems have been comparatively low, but it has been figured out that customer care management system influences customer loyalty level.
