Kualitas perairan tawar dapat dipengaruhi oleh masuknya polutan, misalnya detergen dan pewarna kain sintetis, sehingga berpengaruh terhadap kelangsungan hidup organisme air seperti serangga akuatik (anggang-anggang). Tujuan dari penelitian ini adalah untuk mengetahui toksisitas detergen dan pewarna kain sintetis terhadap angganganggang.Penelitian ini terdiri dari dua faktor, yaitu detergen dan pewarna kain sintetis. Faktor detergen terdiri dari empat konsentrasi yaitu konsentrasi 0, 3, 6 dan 9 ppm, demikian juga dengan pewarna kain sintetis terdiri dari empat konsentrasi yaitu konsentrasi 0, 15, 30 dan 45 ppm. Penelitian ini menggunakan rancangan perlakuan faktorial 4x4 dan rancangan percobaan RAK (Rancangan Acak Kelompok). Hasil penelitian menunjukkan bahwa detergen berpengaruh negatif terhadap daya tahan hidup anggang-anggang dalam waktu 24 jam (P<0,05), demikian juga pengaruh pewarna kain sistesis (P<0,05). Akan tetapi, tidak ada pengaruhinteraksi dari detergen dan pewarna kain sintetis terhadap kematian anggang-anggang (P>0,05). Selain itu, ukuran tubuh memberikan pengaruh yang nyata terhadap waktu kematian anggang-anggang (P<0,05). Dari hasil penelitian dapat disimpulkan bahwa detergen dan pewarna kain sintetis meningkatkan jumlah kematian anggang-anggang dalam 24 jam, namun tidak ada efek interaksi antar kedua perlakuan.

Trigona is a stingless bee, which has been found in tropical and sub-tropical regions. Fifty species have been indentified in South East Asian region, but few studies have been conducted in Indonesia. Plant species commonly differ in different altitudes, due to the climatic effect, therefore will affect the availability of food source for Trigona. This study aimed to investigate the effect of different altitudes to the pollen types collected and used by Trigona as food resources and the distance of their foraging. Samples of Trigona were collected from 3 locations: Location I was in Mawang and Taro Villages at Gianyar Regency, Location II was in Tua Village at Tabanan Regency and Location III was in Ngis Village at Karangasem Regency. The altitudes of those three locations were 750.87 m, 493.007 m and 147.15 m above sea levels respectively. Pollen samples were processed using the acetolysis methods in the Plant Structure and Development Laboratory, Department of Biology, Udayana University and pollen identification was referred to the book of “Pollen Morphology and Plant Taxonomy” (Erdtman, 1972). The results showed that in some cases, the type pollen collected by Trigona differ in different altitude. Pollen of Allamanda cathartica L was collected by the bee at Gianyar and Karangasem Regencies. Pollen of Capsicum frutescens L. and Euphorbia milii were collected by the bee at Tabanan and Karangasem Regency, while pollen Neomarica longifolia was found in bees in all three locations. The average distances of foraging of this Trigona bee was 147.15 m at Gianyar, 162.21 m at Tabanan and 53.61 m at Karangasem.

Polymerase Chain Reaction (PCR) merupakan salah satu metode yang digunakan dalam identifikasi suatu organisme. Identifikasi secara molekular menggunakan metode berbasis PCR perlu dilakukan pada ikan karang Famili Pseudochromidae karena ikan ini mempunyai variasi morfologi warna yang sangat tinggi dan menyulitkan identifikasi morfologi. Metode amplifikasi DNA untuk seluruh spesies ikan anggota famili ini belum banyak dilakukan. Penelitian ini bertujuan untuk mengetahui kondisi optimal untuk amplifikasi DNA menggunakan metode PCR (Polymerase Chain Reaction) pada 25 spesies ikan karang anggota famili Pseudochromidae, yang sebelumnya telah diidentifikasi secara morfologi.Amplifikasi dilakukan pada tiga loki DNA mitokondria, yaitu 16S rRNA, control region dan cytochrome oxidase I (COI). Hasil penelitian menunjukkan kondisi optimum amplifikasi tidak berhubungan dengan perbedaan spesies. Modifikasi amplifikasi dapat dilakukan dengan penambahan volume template DNA dan BSA 1X serta penggantiantemperatur annealing; sedangkan pergantian reagen tidak memberikan pengaruh yang signifikan. Penggunaan primer depan CRK untuk amplifikasi lokus control region juga memberikan hasil yang lebih baik.

Fluctuation of water regimes where plant grows has been known to affect the plant chemical, nutrition compositions and plant chemical defenses, which can affect the vulnerability of plants to insect herbivores. This research aimed to compare the concentration of plant nutrition and chemical defenses of Melaleuca ercifolia grows on different water regimes, subsequently to insect herbivore attacks. The leaf total nitrogen was higher in plants growing in water fluctuated areas, therefore the insect herbivores compared to plants growing in prolong-flooded condition. Insect herbivores prefer to consume plants that are more nutritious and less affected by the plant growing conditions.

Pantai Mengiat Nusa Dua, Bali merupakan salah satu pantai yang memiliki ekosistem padang lamun dengan keanekaragaman makrozoobenthos yang melimpah. Padang lamun (Seagrass) merupakan tumbuhan tingkat tinggi dan berbunga (Angiospermae) yang hidup terendam pada dasar perairan laut dangkal. Salah satu kelompok biota laut yang sering dijumpai pada kawasan padang lamun adalah jenis makrozoobenthos. Penelitian ini dilaksanakan pada bulan Januari - Maret 2021. Tujuan penelitian ini adalah untuk mengetahui kerapatan ekosistem lamun, kelimpahan makrozoobenthos serta hubungan kerapatan lamun dengan kelimpahan makrozoobenthos di Perairan Pantai Mengiat Nusa Dua, Bali. Sampel lamun dan makrozoobenthos diambil menggunakan transek kuadrat berukuran 0,5 x 0,5 m dengan 30 titik pada 3 stasiun dengan jarak 20 m antar titik. Spesies lamun yang ditemukan di Pantai Mengiat membentuk vegetasi campuran dengan 7 spesies lamun dengan kerapatan jenis tertinggi ditemukan pada Cymodocea rotundata. Makrozoobenthos yang ditemukan pada penelitian ini meliputi 1 spesies dari Kelas Bivalvia dan 14 spesies dari Kelas Gastropoda. Hubungan kerapatan lamun dengan kelimpahan makrozoobenthos menunjukkan hubungan yang kuat dengan nilai korelasi -0,765 dan menunjukkan arah negatif (-), dimana semakin tinggi nilai kerapatan lamun maka kelimpahan makrozoobenthos akan semakin rendah.

This research is conducted to find out the genetic profiles of Kayuan clan which is belong to Pasek Catur Sanak Bali Mula, indigenous Balinese people. The DNA profiles is identified by using Microsatellite DNA of Y chromosome. Genes or DNA in Y chromosome are descended from father to son (patrilinealism). Four loci of microsatellite DNA from Y chromosome are used, including DYS19, DYS390, DYS393 and DYS395 to amplified DNA samples from 67 males probands. The probands are people of Kayuan clan from Siakin, Songan, Blandingan and Kutuh villages, Kintamani sub district and others are originally from Jehem village, Tembuku sub district, Bangli regency. The research found 12 allele varieties from all the analyzed loci, which resulted in low genetic diversity (0.33 + 0.001). There are 4 combinations alleles of 4 loci that created12 various haplotypes, the greatest one is haplotype 1 (0.39), followed by haplotype 2 (0.16), haplotype 7 (0,12) and the smallest one is haplotype 6 (0,10). On the other hand, eight other alleles found on the smaller frequencies. Two similar allele combinations were also found on DNA profiles of Celagi clan, which is also belong to the similar family, Pasek Catur Sanak Bali Mula. The two allele are haplotype 6 and 5 found in both, Pasek Kayuan and Pasek Celagi. The haplotype 6 as dominant allele of Celagi clan by adoption, haplotype 5 however, the frequency was the lowest. This allele only detected in one member of each clan due to mutation.
