Abstract

Mangrove in marine ecosystem have function to help continuing food chain directly, provide food for benthics organism, include macrozoo and microzoo, and ephiphyte  and indirectly as habitat, nursery ground and spawning ground (Nontji (1993), Valiela et al, (2001).  This research analyzed macrozoobenthics community in mangrove forest, Penyu Island, Tanjung Benoa, and counting correlation between mangrove density and macrozoobenthics abundance. 4 mangroves species (Bruguiera gymnorrhiza, Rhizopora mucronata, Rhizopora stylosa dan Sonneratia alba) and 22 macrozoobenthics genus (Cvpraeidae, Naticidae, Cerithiidae, Mathildidae, Mitridae, Columbellidae, Buccinidae, Neritidae, Fasciolariidae, Smaragdinellidae, Littorinidae, Trochidae, Costellariidae, Terebridae, Opisthobranchia, Pyramidellomorpha, Littorinidae, Conidae, Thaididae, Potamididae, Turritellidae, Nassariidae) were identified from 3 stasions over the Island. Rhizopora stylosa have the highest importance index in Penyu Island mangroves community and than Bruguiera gymnorrhiza. The highest abundance documented in station 1 for 385.2 ind/m2 and then station 2 for 271.58 ind/m2 and the lowest is station 3 247.71 ind/m2. Cerithium sp recorded as dominant species and Turritella cochlea and Cyprae kieneri as inferior species. Macrozoobenthos community in Penyu Island is being stable base d on high diversity index, moderate eveness index and low dominance index. The regression equation acquired Y = -60.524X + 119.94 and revealed correlation 40.05% and explain 16.04% macrozoobenthics varians. From the study inconclusive there are no correlation between mangroves density and macrozoobenthics abundance.

Abstract

ABSTRAKPemutihan karang merupakan salah satu dampak dari perubahan iklim global, kenaikan suhu tersebut memberikan dampak negatif bagi keseimbangan ekosistem terumbu karang. ­Terumbu karang yang memutih dan kehilangan zooxanthella nya akan rentan terkena infeksi dan penyakit. Populasi komunitas ikan karang pemakan hewan karang dan makrozoobenthos juga akan menurun. Tujuan dari penelitian ini adalah untuk mengetahui besar dampak kerusa­kan terumbu karang dan dampaknya bagi populasi ikan dan makrozoobenthos. Survey dilakukan pada 3 titik di wilayah perairan Tejakula dengan metode reefcheck. Hasil penelitian menunjukkan kematian terumbu karang sebesar 5-7.5%, jumlah alga yang menutupi 3.125%. Kondisi ikan kepe-kepe yang merupakan pemakan hewan karang juga sudah ditemukan dalam jumlah cukup banyak. Keberadaan ikan herbivora dan makrozoobenthos herbivore membantu mengurangi jumlah alga yang menutupi. Sedangkan keberadaan ikan pemakan terumbu karang dan ikan predator memperlihatkan bahwa sistem ekologi yang ada di terumbu karang tersebut hampir kembali normal. Kata Kunci: terumbu karang, komunitas ikan karang, makrozoobenthos.The Impact of Hard Coral Bleaching in Coral and Macrozoobenthos Fish Communities in Tejakula, Buleleng, Bali Water AreasABSTRACTCoral bleaching is one of the consequences of global climate change, as the rise of temperature negatively impacts the ecological balance of reef ecosystems. Bleached coral reefs lose their zooxanthellae, increasing vulnerability to infection and disease and consequently, causing population decline of macrozoobenthos and reef fish communities which prey on coral-consuming organisms. This research aims to determine the degree of coral reef damage and its impact on fish and macrozoobenthos population. The survey was conducted on 3 stations in Tejakula waters with the reef check method. Results show that coral reef death reaches 5-7.5%, with algal coverage of 3.125%. Kepe-kepe fish which prey on coral-consuming animals were also found in relatively high abundance. The presence of herbivore fish and macrozoobenthos help reduce algal cover. Meanwhile, the presence of coral-consuming and predator fish indicate that the coral reef ecological system has mostly returned to normal. Keywords: coral reef, reef fish community, macrozoobenthos

Abstract

Seagrass has function as nursery ground, spawning ground, feeding ground and habitat for many coastal organism (benthic, fish and epiphytes). Tourism activities in Sanur beach, the habitat of seagrass, could change the water condition, it indirectly influencing the existences of seagrass plants and periphyton in Sanur beach. The aim of this study are to analyze community structure of periphyton on seagrass leaves (Thalassia hemprichii and Cymodocea rotundatta) and its relationship with water parameters in four stations at Sanur beach area that has the unique characteristics. Water parameters measured were temperature, salinity, DO (Dissolved oxyen), pH, nitrate, phosphate, and TSS (Total Suspended Solid). Data analysis using PCA (Principal Component Analysis) to see the parameters that most influence on the abundance of periphyton. The results showed diversity index (H?) of periphyton is moderate, eveness index (E) moderate to high, and dominance index (C) is low to medium. It concluded that conditions of Sanur waters is stable but it is easily changed due to anthropogenic influences. PCA analysis showed that the parameters of the water have different effects on the abundance of periphyton at each seagrass leaves. Periphyton on Thalassia hemprichii was influenced by TSS, while Cymodocea rotundatta was influenced by phosphate, nitrate, temperature, DO, and TSS.

Abstract

Isolator merupakan salah satu alat yang berfungsi untuk menjaga kehandalan sebuah sistem tenaga listrik. Saat ini jenis isolator yang sedang dikembangkan adalah isolator jenis polimer. Isolator polimer memiliki banyak keunggulan dibandingkan isolator keramik dan gelas. Namun karena banyak digunakan sebagai isolator pasangan luar, isolator ini kinerjanya diperngaruhi oleh kondisi lingkungan yang secara tidak langsung juga dipengaruhi oleh kondisi permukaan isolator. Pada penelitian ini dilakukan pengujian dengan kondisi permukaan awal, halus dan coating menggunakan silicon rubber RTV 683. Kondisi pengujian isolator dilakukan pada kondisi kering serta basah dengan variasi tengangan 11-15 kV. Parameter yang diukur yaitu sudut kontak, arus bocor dan THD. Hasil penelitian menunjukkan bahwa isolator yang telah mengalami coating memiliki hasil yang terbaik. Sudut kontak yang terukur sebesar 91,1o. Saat kondisi kering arus bocornya adalah 2,6-3,10 mA dan nilai THD 14,33-16,59%. Sementara saat kondisi basah arus bocor 3,26-3,77 mA dan nilai THD 12,18-16,43%. Dari hasil tersebut dapat disimpulkan bahwa isolator yang telah di coating bersifat hidrofobik karena sudut kontaknya lebih dari 90o. Sedangkan menurut IEC 950 Safety Standart arus bocor saat kondisi kering sudah dibawah standart yaitu 3,5mA tetapi nilai THD masih di atas standart yang ditentukan oleh IEEE 519-1992 yaitu 5%.

Abstract

Thalassia hemprichii is one of the seagrass as favorite food of two protected herbivores such as Green Turtle and Dugong. The existence of Thalassia hemprichii and knowing the growth rate becomes very important for sustainability of two herbivores. The study was conducted in Tanjung Benoa waters that covering three parts of the coast such as Samuh, Conrad and Tanjung beach in February until March 2017. Thalassia hemprichii leaves growth is observed consist of long and heavy growth (dry weight) and measured leaf age that has been observed such as young, half old and old leaves. The method that used to measure the growth of Thalassia hemprichii is pruning method and determination the research location using purposive sampling method. The aim of this research is explained the growth rate, biomass, and productivity of young leaves, old leaves of Thalassia hemprichii in Tanjung Benoa Bali. Measurement results of Thalassia hemprichii growth between age group of leaves has different young leaves faster growth if compared with the half old leaves and old leaves with average growth is 3.41mm/day indicates that the efficiency of this seagrass growth will decrease as the leaves age. The highest biomass values ??were found in older leaves if compared with young leaves and half-old leaves with average 0.205 gbk/m2 expected because the thick and wide leaf size will produced larger leaf biomass. The highest productivity value is found in oldest leaves in each station with average 0.028 gbk/m2/day expected morphology and different nutrient content in each leaf tissue.

Abstract

The population of olive ridley has declined in Indonesia, so that efforts are needed to preserve this turtle population through conservation. In conservation of olive ridley, the selection of the precise feed will affect for a good growth. Feed that has high protein content one of them is dried rebon shrimp and tongkol fish. The utilization of feed from dried rebon shrimp and tongkol fish, especially mix feed of these two feeds for olive ridley baby is still very limited information. This research aims to determine the comparison growth rate of olive ridley with a feeding of tongkol fish, dried rebon shrimp and mixed feed also to know the percentage of feed efficiency. The research was conducted for six weeks at the conservation center TCEC Serangan, Bali. The design method used was Completely Randomized Design (CDR) with one control and three treatments, each treatment getting five repetitions. ANOVA analysis was used to analyze the mean differences between groups and the calculation of feed efficiency was performed to see the percentage of feed that was most efficient in the body of the hatch. The results showed different feeds gave different growth rates. The high protein on mixed feeds has produced the highest growth rates compared with dried rebon shrimp and tongkol fish feed. Similarly, the percentage efficiency of mixed feed is more efficient compared with dried rebon shrimp and tongkol fish feed.
