Judul: Kinerja Pengelolaan Air dan Air Limbah Di PT TIFICO Tangerang
Abstrak: Sektor industri merupakan sektor yang rentan dengan masalah lingkungan Salah satu perusahaan yang bergerak di sektor industri adalah PT Teijin Indonesia Fiber Corporation (PT TIFICO) di Kelurahan Panunggangan Kecamatan Pinang Kota Tangerang dan Kelurahan Paku Alam Kecamatan Serpong Kabupaten Tangerang yang menghasilkan produk utama “Polyester” dengan memiliki lahan seluas 60 ha. Tujuan penelitian ini adalah adalah mengidentifikasi sumber limbah cair dengan metode neraca air, melakukan studi kecenderungan perubahan kualitas limbah cair dengan menggunakan SPSS versi 11.0, melakukan analisis finansial pengelolaan limbah cair dengan mengunakan metode benefit cost ratio, mengukur kinerja pengelolaan perusahaan berdasarkan persepsi karyawan, instansi terkait (Dinas Lingkungan Hidup Kabupaten / Kota Tangerang atau Bapedal Propinsi Banten ) dan masyarakat dengan metode deskriptif.

Judul: Pengaruh penggunaan faktor-faktor produksi terhadap jumlah dan debit serta aspek finansial pengolahan limbah cair industri tekstil
Abstrak: Tujuan penelitian ini adalah: (1) mengetahui pengaruh perubahan tingkat produksi, pemakaian air, pemakaian bahan baku kapas, pemakaian bahan baku polyester, dan pemakaian bahan kimia untuk produksi terhadap jumlah dan debit limbah cair, (2) menghitung total biaya pengolahan limbah cair dan perubahan biaya dan manfaat yang dihadapi perusahaan dengan adanya Instalasi Pengolahan Air Limbah (IPAL), (3) menghitung proporsi antara biaya yang ditanggung perusahaan dan yang dikenakan pada harga produknya, dan (4) menganalisis faktor-faktor yang mendasari keputusan perusahaan untuk mendirikan IPAL. Perkembangan industri di Indonesia selain memberi dampak positif terhadap perekonomian, juga mengakibatkan terjadinya masalah penurunan mutu lingkungan hidup. Menyadari ancaman pencemaran lingkungan tersebut, pemerintah maupun konsumen pemakai produk industri semakin memperhatikan sisi keamanan lingkungan (environmental safety) dari produk yang dipasarkan, terlebih lagi konsumen di pasar internasional. Sebagai salah satu industri yang berorientasi ekspor, industri tekstil juga menghadapi tuntutan tersebut. Karena eksternalitas negatif dari proses produksi tekstil diantaranya dalam bentuk limbah cair, maka pengolahan limbah cair (Waste Water Treatment) merupakan salah satu cara menginternalisasikan efek eksternalitas negatif tersebut…dst

Judul: Systematics of Desmos (Annonaceae) in Malesia
Abstrak: Desmos is a woody climbing genus of Annonaceae which has been widely used as traditional medicine in several countries such as China, Indo-China, Thailand, and Peninsular Malaysia to treat dysentery, vertigo, fever, and postpartum. Phylogenetic studies on Desmos showed a close relationship between Desmos and Dasymaschalon. They share similar moniliform monocarpic fruits, but their flowers are different. It has been debated among Annonaceae researchers whether both genera should be treated as the same or distinct genus. Therefore, investigation on the taxonomic delimitation of Desmos species and Dasymaschalon will be necessary. Plastid genome (plastome) identification, leaf epidermal section of Desmos species and Dasymaschalon species, a taxonomic revision of Desmos in Malesia using morphological data, the spatial distribution of Desmos species in Malesia, and morphological and genetic variation in Desmos chinensis population using ISSR marker were used to investigate taxonomic delimitation of Desmos. Plastome study of Desmos chinensis and Dasymaschalon dasymaschalum was carried out to determine the origin, evolution, phylogenomics, and identify marker candidates for Desmos and Dasymaschalon or with other genera in Annonaceae. We discovered that the plastome of Desmos chinensis was circular with the size of 167,677 bp (smaller than Dasymaschalon dasymaschalum), consist of 111 genes, including 78 protein-coding genes, 29 transfer RNAs, and 4 ribosomal RNAs. The plastome showed a typical quadripartite structure, i.e., large single copy (LSC), small single copy (SSC), and two inverted repeats (IRs). The plastome of Dasymaschalon dasymaschalum was 191,488 bp in length, which also exhibited a typical quadripartite structure (LSC, SSC, and two IRs). Desmos chinensis and Dasymaschalon dasymaschalum showed different copies of accD, ndhD, ndhF, rps18, and ycf2. Protein coding genes of rpoB, rpoC1, rbcL, matK, rpl32, infA, and rpl36 were identified based on nucleotide diversity, sequence variability, and parsimony-informative sites. The genes are defined as molecular marker candidates of plastome for phylogenetic, barcoding, and population genetic research. We predicted that Desmos chinensis and Dasymaschalon dasymaschalum separated at ca. 64 million years ago during the Paleocene. Leaf anatomical feature study was carried to support the taxonomic delimitation of interspecific Desmos and intergeneric of Desmos and Dasymaschalon. Leaf anatomy in the paradermal section of 20 taxa (12 species of Desmos, eight species of Dasymaschalon) have been carried out. According to the leaf epidermal section, Desmos and Dasymaschalon are two distinct genera mainly distinguished based on the anticlinal wall undulation of epidermal cells and supported by variation of the crystal type and size. The anticlinal wall undulation of Desmos was almost straight to slightly wavy and never sinuous; meanwhile, Dasymaschalon varies from almost straight to deeply sinusoid. The crystals of Desmos consist of rhombohedral, druse type A, and druse type B crystals, whereas Dasymaschalon has prism, druse type A, druse type B, and druse type C crystals. The recent taxonomic revision using the morphological data was mainly based on the examination of about 1374 specimens from BO, L, WAN, ANDA, SING, SAN, K, P, HUH herbaria. The Desmos species in Malesia consists of eight species: D. acutus, D. chinensis, D. chryseus, D. dunalii, D. pedunculosus, D. subbiglandulosus, two new records: D. lawii and D. macrocarpus, and one
