Extraction was carried out by maceration using ethanol solvent. The liquid dilution method was used as an antibacterial bioactivity testing. The antibacterial bioactivity test results showed that the extract had antibacterial activity. In Staphylococcus aureus bacteria, concentrations extract of 90% were determined as MIC values, MRSA of concentrations extract of 30 were determined as MIC values, and in Salmonella typhi at concentrations extract of 30% set as MIC values. The antibacterial bioactivity test results were analyzed using One Way Anova method, followed by the Tukey Test. Anova's data showed that the growth of colonies in each concentration of extract was significant, meaning that each concentration was significantly different in inhibiting bacterial growth. However, the MBC value could not be determined because it still experienced colony growth in the results of MBC testing.Keywords: Galaxaura oblongata, bioactivity, chemical compound, antibacterial.

Abstract

Abstrak  Tanaman daluga (Cyrtosperma spp.) termasuk dalam famili Araceae (talas-talasan), umbinya berpotensi sebagai tanaman pangan alternatif karena mempunyai nilai gizi yang tinggi. Tanaman ini banyak terdapat di Kepulauan Sangihe. Penelitian ini dilakukan untuk mengetahui DNA barcoding daluga hijau, kuning dan belang-belang dengan menggunakan gen matK (maturase K). Ekstraksi DNA menggunakan Genomic DNA Mini Kit Plant (Geneaid), amplifikasi DNA menggunakan Kit PCR 5x FirePol Master Mix (Solis Biodyne) dan sepasang primer universal yaitu matK-3F-r (5’CGTACAGTACTTTTGTGTTTACGAG 3’) dan matK-1R-f (5’ACC CAGTCCATCTGGAAATCTTGGTTC3’). Hasil penelitian menunjukkan bahwa tanaman daluga hijau, daluga kuning, dan daluga belang-belang dari Kepulauan Sangihe memiliki sekuens DNA yang identik (kemiripan 100%). Daluga yang diteliti memiliki kemiripan sekuens dengan sampel di NCBI yaitu dengan Cyrtosperma macrotum (99,88%), Podolasia stipitata (99,50%), Dracontium polyphyllum (99,38 %), Pycnospatha arietina (99,38%) dan Dracontioides desciscen (99%). Dari hasil penelitian ini dapat disimpulkan bahwa DNA barcoding tanaman daluga dari kepulauan Sangihe berdasarkan gen matK belum dapat membedakan variasi intraspesies. Kata kunci: daluga, dalugha, Cyrtosperma spp. Abstract  Daluga (Cyrtosperma spp.) plant belongs to the family Araceae, the corm is potential as an alternative food because it has a high nutritional value. The plant is widely available in Sangihe Island. This study aimed to determine the DNA barcoding of green daluga, yellow daluga and mottled daluga using matK gene (maturase K). The DNA extraction used Genomic DNA Mini Kit Plant (Geneaid) and DNA amplification used the Kit PCR 5x FirePol Master Mix (Solis Biodyne) and universal primers matK-3F-R (5' CGTACAGTACTT TTGTGTTTACGAG 3') and matK-1R-f (5'ACCCAGAAATGGATCTCTTCCTGG TTC3'). The result showed that the green daluga, yellow daluga and mottled daluga from Sangihe Islands were identical (100% similarity). Daluga from Sangihe had similarities with the sample sequences in NCBI, namely Cyrtosperma macrotum (99.88%), Podolasia stipitata (99.50%), Dracontium polyphyllum (99,38%) Pycnospatha arietina (99.38%) and Dracontioides desciscen (99%). From these results it could be concluded that DNA barcoding of daluga plant from Sangihe based on the matK gene could not  distinguish variations intraspesies.

Abstract

AbstrakSurvei ini dilaksanakan untuk menginventarisasi jenis-jenis mamalia, burung, dan reptil liar yang dikonsumsi oleh masyarakat Sulawesi Utara dalam kaitannya dengan aspek konservasi dan pemanfaatannya. Metode yang digunakan dalam penelitian ini adalah survei dari tahun 2006 sampai 2010 berdasarkan jenis-jenis yang diperdagangkan di pasar-pasar tradisional, kasus perburuan satwa liar, dan jenis-jenis yang disediakan dalam menu masyarakat pada pesta-pesta adat. Dari survei diperoleh hasil terdapat 39 jenis mamalia, burung, dan reptil liar yang dikonsumsi oleh masyarakat Sulawesi Utara. Konsumsi satwa liar telah menjadi kebiasaan bagi bagi masyarakatnya dan merupakan faktor utama penyebab penurunan populasi satwa liar. Banyak jenis satwa yang dikonsumsi, beberapa termasuk dilindungi, masuk daftar terancam IUCN, dan masuk dalam appendix CITES. Oleh sebab itu pemanfaatan beberapa jenis satwa liar harus mengikuti peraturan perlindungan dan upaya penangkaran tikus ekor putih (Paruromys dominator), babi hutan (Sus celebensis), dan rusa (Cervus timorensis) sangat memungkinkan dan memiliki nilai ekonomi yang tinggi.Kata kunci: burung, mamalia, reptil, Sulawesi UtaraAbstractThis survey was conducted to collect information about wild mammals, birds and reptiles consumed by North Sulawesi people regarding with its conservation aspect and utilization. The used method was survey from 2006 to 2010 based on the animal species sold in some traditional markets, hunting cases and serving food in traditional party menu in Bitung City, Tomohon City and North Minahasa District. The result showed that there were 39 consumed species of wild mammals, birds and reptiles. Consumption of wild animal by local people has become a tradition for the community and it mostly resulted in the decline of wild animal population. Some species are included in IUCN Redlist and CITES Appendices. Therefore, all protection laws should be followed in the utilization of those species. In addition, breeding programme of Sulawesi giant rat (Paruromys dominator), Sulawesi Wild Boar (Sus celebensis) and Timor Deer (Cervus timorensis), is very prospective as it has economically value.Keywords: birds, mammals, reptiles, North Sulawesi

Abstract

Abstract The definition of soil quality encompasses physical, chemical and biological characteristics, and it is related to fertility and soil health. Soil enzyme activities are the direct expression of the soil community to metabolic requirements and available nutrients, can be used as soil quality indicators. Among all enzymes in the soil environment, dehydrogenases are one of the most important, and are used as indicator of overall soil microbial activity. Flooded soils present a unique situation since they are predominantly under anaerobic conditions in several physical, chemical, and biological characteristics. Flooding changes the chemistry, microbiological properties, and nutrient supply capacity of soil. In particular, the effect of flooding causes an increase on soil dehydrogenase activity. This review examines selected papers containing soil dehydrogenase activities in flooded soil that could be used to determined effect of flooding on soil dehydrogenase activity. Keywords: dehydrogenase activities, flooded soils, soil quality Abstrak Definisi kualitas tanah meliputi faktor fisik, kimia dan biologi, dan terkait dengan kesuburan dan kesehatan tanah. Aktivitas enzim tanah adalah ekspresi langsung dari komunitas tanah untuk melakukan proses metabolik untuk menghasilkan nutrisi, dan dapat digunakan sebagai indikator kualitas tanah. Di antara semua enzim dalam lingkungan tanah, dehydrogenase adalah salah satu yang paling penting, dan digunakan sebagai indikator aktivitas mikroba tanah secara keseluruhan. Tanah sawah dengan kondisi tergenang menyajikan situasi yang unik karena secara fisik, kimia, dan biologi berada dalam kondisi anaerob. Penggenangan menyebabkan terjadinya perubahan secara kimia, mikrobiologi, dan kapasitas pasokan hara tanah. Secara khusus, Efek penggenangan menyebabkan peningkatan aktivitas dehidrogenase tanah. Tulisan ini mengkaji beberapa penelitian mengenai aktivitas dehidrogenase pada tanah sawah, yang dapat digunakan untuk menentukan efek pengenangan terhadap aktivitas dehidrogenase tanah. Kata Kunci: aktivitas dehidrogenase, tanah sawah, kualitas tanah

Abstrak   Telah dilakukan penelitian mengenai hubungan kekerabatan pada delapan kultivar talas (Colocasia esculenta) berdasarkan karakter morfologi organ vegetatif. Kultivar-kultivar tersebut yakni talas kaliurang, burkok, bentul, bogor, sutra, kudo, lampung dan semir. Total karakter yang diamati berjumlah 35 karakter. Karakter-karakter tersebut kemudian dibuat skoring. Hasil skoring dianalisis dengan metode UPGMA (Unwight Pair Group Method with Arithmetic Average) menggunakan program komputer PAUP versi 4.0b10 sehingga terbentuk fenogram. Hasil penelitian menunjukkan variasi morfologi organ vegetatif yang cukup tinggi. Dari seluruh karakter, hanya lima karakter yang tidak menunjukkan adanya perbedaan. Karakter tersebut yaitu bentuk daun dan ujung daun, rasio panjang terhadap lebar daun, pola tepi pelepah dan posisi dominan bentuk helai daun tua. Dari fenogram diketahui bahwa seluruh kultivar yang diamati membentuk dua kelompok utama. Kelompok pertama terdiri dari kaliurang, burkok, bentul, bogor, lampung dan sutra, yang membentuk tiga subkelompok. Kelompok kedua terdiri dari kudo dan semir. Hasil analisis fenetik menunjukkan kultivar bogor dan lampung merupakan dua kultivar yang sangat dekat hubungan kekerabatannya dengan nilai kesamaan sebesar 80%.
