Judul: Analisis finansial pengoperasian Unit Pengolahan Air Bersih (Water Treatment Plant) Kampus IPB Dramaga Bogor
Abstrak: Air merupakan kebutuhan pokok setiap orang, karena tanpa air kehidupan tidak akan berlangsung dengan baik. Sehingga pengembangan dan pengelolaan sumberdaya air sangatlah berperan penting dalam memenuhi kebutuhan air bersih. Penyediaan air bersih oleh Institut Pertanian Bogor saat ini menggunakan unit pengolahan air bersih atau water treatment plant (WTP). Terdapat 7 unit WTP yang mengolah air baku dari dua sumber, yaitu Sungai Cihideung dan Sungai Ciapus. Sebagai langkah untuk mengevaluasi dan pengembangan WTP yang ada di kampus IPB Dramaga, maka harus dilakukan analisis mengenai operasional maupun ekonomi.

Judul: Evaluation of Water Quality and Performance of Clean Water Treatment Plant at WTP Ciapus Dramaga IPB Campus
Abstrak: Air memiliki peran penting bagi kelangsungan hidup semua makhluk hidup di bumi ini. Agar air layak untuk dikonsumsi, maka harus melalui proses Water Treatment Plant (WTP). IPB memiliki berbagai sumber air yang berasal dari dua WTP, yaitu WTP Cihideung dan WTP Ciapus. Penelitian ini bertujuan untuk mengevaluasi kualitas air serta mengevaluasi kinerja WTP Ciapus. Penelitian ini dilakukan dalam dua tahap, tahap pengumpulan dan pengambilan data dan tahap pengolahan data. Lokasi penelitian ini di WTP Ciapus, Kampus IPB Dramaga, Bogor, Jawa Barat. Kualitas air yang dihasilkan oleh Water Treatment Plant Ciapus masih cukup baik, suhu terendah dan tertinggi adalah sebesar 25,8oC dan 27,3oC, nilai TDS tertinggi adalah 99,3 mg/l, kadar sulfat dan kadar nitrit tertinggi adalah sebesar 36,143 mg/l dan 0,0678 mg/l, serta untuk pH masih berada pada rentang 6,5-7,2, sedangkan pada parameter kekeruhan masih terdapat nilai di atas 5 NTU. Hasil evaluasi kinerja unit didapat beberapa nilai parameter yang belum sesuai dengan kriteria desain, yaitu waktu detensi dan gradien kecepatan pada koagulasi, nilai beban pelimpah dan waktu tinggal pada sedimentasi, kecepatan penyaringan serta kecepatan pencucian pada unit filtrasi, sedangkan pada unit flokulasi sudah sesuai dengan baku mutu.

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
