Judul: Strategi kebijakan pengelolaan kualitas air di Pelabuhan Muara Angke Jakarta Utara
Abstrak: Pelabuhan Muara Angke merupakan salah satu pelabuhan yang terletak di wilayah Teluk Jakarta. Letaknya yang sangat strategis dan didukung oleh sumberdaya alam sehingga menyebabkan tejadinya peningkatan aktivitas manusia, baik di darat maupun di lautan. Dari aktivitas ini menghasilkan limbah berupa limbah padat dan cair, sehingga menyebabkan terjadinya pencemaran terhadap kualitas air di sekitar kawasan Pelabuhan Muam Angke.

Judul: Management Strategy for Liquid Waste of Fish Processing Units in the Muara Angke Fishing Port North Jakarta
Abstrak: Pelabuhan Perikanan Nusantara (PPN) Muara Angke belum memiliki Instalasi Pengolahan Air Limbah (IPAL) sehingga hampir semua Unit Pengolahan Ikan (UPI) membuang limbah tanpa diolah. Kondisi tersebut dalam jangka panjang dapat berpotensi menyebabkan pencemaran lingkungan, sehingga perlu adanya kajian terkait pengelolaan limbah cair dari UPI di kawasan PPN Muara Angke. Penelitian ini bertujuan untuk mengidentifikasi pengelolaan limbah cair unit pengolahan ikan di PPN Muara Angke, Membandingkan kualitas limbah cair unit pengolahan ikan dengan baku mutu limbah industri pengolahan ikan berdasarkan PERMEN-LH No. 05 Tahun 2014, serta Merumuskan strategi pengelolaan limbah cair unit pengolahan ikan di PPN Muara Angke. Data untuk mengidentifikasi pengelolaan limbah cair UPI dan membuat strateginya dikumpulkan melalui wawancara dengan kuesioner menggunakan metode snowball sampling dan purposive sampling sedangkan data kualitas air di salah satu industri UPI diperoleh dari mengambil sampling air pada saluran sebelum masuk ke perairan penerima air limbah. Analisis deskriptif, analisis komparatif deskriptif, dan analisis SWOT digunakan dalam penelitian ini. Hasil penelitian menunjukan pengelolaan limbah cair UPI belum optimal. Kualitas air limbah UPI menunjukkan hampir semua masih dibawah baku mutu dan hanya satu yang diatas baku mutu, yaitu parameter TSS. Strategi pengelolaan limbah cair UPI di PPN Muara Angke terdiri dari delapan strategi. Strategi merumuskan SOP penanganan limbah cair industri UPI di PPN Muara Angke, strategi uji kualitas air baik di UPI dan di perairan, dan strategi menyediakan fasilitas IPAL terpadu menjadi prioritas. Kata Kunci: industri pengolahan ikan, limbah cair, pencemaran lingkungan, PPN Muara Angke, strategi, The Muara Angke Fishing Port (PPN) does not yet have a Wastewater Treatment Plant (WTP) so that almost all Fish Processing Units (UPI) dispose of waste without being processed. In the long term, these conditions can potentially cause environmental pollution, so it is necessary to conduct a study related to the management of liquid waste from UPI in the PPN Muara Angke area. This study aims to identify the management of fish processing unit wastewater at PPN Muara Angke, compare the quality of fish processing unit wastewater with the quality standards of fish processing industry waste based on Permen LH No. 05 of 2014, as well as formulating a strategy for managing fish processing unit wastewater at PPN Muara Angke. Data to identify UPI wastewater management and formulate a strategy were collected through interviews with questionnaires using the snowball sampling and purposive sampling methods, while water quality data in one of the UPI industries were obtained from taking water samples in the canal before entering the wastewater receiving waters. Descriptive analysis, descriptive comparative analysis, and SWOT analysis were used in this study. The results showed that UPI's liquid waste management was not optimal. The quality of UPI's wastewater shows that almost all of it is still below the quality standard and only one is above the quality standard, namely the TSS parameter. UPI's liquid waste management strategy at PPN Muara Angke consists of eight strategies. The strategy formulating SOPs for handling UPI industrial liquid waste at PPN Muara Angke, strategy testing water quality both at UPI and in the waters, and strategy providing integrated WTP facilities are priorities.

Judul: Phylogenetic analysis of subgenus Dieramalpinia (Alpinia carolinensis clade) - Zingiberaceae based on ITS sequences
Abstrak: The most recent infra-generic classification of Alpinia Roxb. by Smith divided the genus into two subgenera (Alpinia and Dieramalpinia) with 11 sections and 12 subsections. One of the sections of Alpinia subgenus Dieramalpinia is Myriocrater which contains about 16 species. The most recent phylogenetic study that included species from Alpinia subgenus Dieramalpinia was done by Kress et al. (2007). They sampled only eight species and found that these were nested within a clade referred to as the Alpinia carolinensis clade. This clade was well supported and may be separated as a genus if sampling more species confirms the result. The objectives of the present project are to compare ITS within one species; to test the monophyly of Alpinia section Myriocrater; to test whether adding more samples still supports the Alpinia carolinensis clade. The present study included thirty-nine samples representing nineteen taxa from Alpinia; seven samples are still unidentified at species level. Sequences of the Internal Transcribed Spacer were used in the analysis. The result showed that ITS sequence of Myriocrater’s species are more conserved than another group in Zingiberaceae. There are base variations within species level. The Alpinia section Myriocrater plus five species from other section is not monophyletic. The Alpinia carolinensis clade still includes three sections of Smith classification (Dieramalpinia, Myriocrater and Pycnanthus) from subgenus Dieramalpinia. Alpinia subgenus Dieramalpinia section Eubractea and one species of section Dieramalpinia are separated into another clade.
