Judul: Implementasi LCA (Life Cycle Assessment) pada Bata Merah dan Batako
Abstrak: Red brick and brick are important materials on building project as like house. Purpose this research is determine the material between red brick and brick who have less impact to environment. LCA is one of method to evaluate impact assessment for a project or product. LCA ISO 14040 stage include goal definition and scoping, inventory analysis, impact assessment, and interpretation. Result this research is raw materials of red brick to make walls which function unit 1m2 wall soil 64 liter, and water 1 liter. Raw materials of brick to make 1 m2 walls is soil 45 liter, limestone 11 liter, and water 1 liter. Noise level of redbrick fabric is 83 dB(A). Noise level of brick fabric is 57 dB(A). Value the noise level of redbrick industry was exceeds the quality standards specified in the Decree of the Minister of Environment No.:KEP-48/MENLH/11/1996 pertaining on Noise Threshold. Energy consumption to make redbrick for 1 m2 walls was 2047 kcal whereas energy consumption for to make 1 m2 brick was 186 kcal. Based on the method of LCA (Life Cycle Assessment), the best material for make walls between redbrick and brick was a brick.

Judul: Penilaian Daur Hidup (Life Cycle Assessment) Produksi Beras Pandanwangi Cianjur
Abstrak: Tujuan penelitian ini adalah menganalisis dampak lingkungan berupa emisi yang dapat ditimbulkan dari sistem produksi beras pandanwangi dalam satu siklus dengan menggunakan metode Life Cycle Assessment (LCA). LCA adalah suatu metode yang dapat digunakan untuk mengevaluasi dampak lingkungan yang disebabkan oleh suatu produk selama proses produksi atau aktivitas selama siklus hidupnya. Metode LCA terdiri atas 4 tahapan yaitu tujuan dan ruang lingkup, analisis inventori, penghitungan dampak dan interpretasi hasil. Analisis LCA yang dilakukan menggunakan metode IPCC dengan menghitung nilai emisi CO2 dan emisi non CO2. Analisis dilakukan untuk mendapatkan dampak lingkungan yang dapat ditimbulkan dari 1 kg produk beras pandanwangi yang dihasilkan. Perhitungan nilai emisi total menunjukan bahwa dari 1 kg beras pandanwangi yang produksi menghasilkan emisi sebesar 1,71 kg CO2-eq dengan konsumsi energi sebesar 4.768,5 MJ/ton beras. Perhitungan net energi didapatkan nilai Net Energy Value (NEV) sebesar 16,46 GJ dan nilai Net Energy Ratio (NER) sebesar 4,45. Sedangkan emisi non-CO2 terbesar yang diperoleh dari kegiatan budidaya padi berupa CH4. Besarnya nilai emisi CH4 dipengaruhi oleh tingginya penggunaan pupuk sintetik pada lahan. Pengelolaan limbah produksi beras yang efektif mampu mengurangi nilai emisi pada produksi beras pandanwangi.

Judul: Studi Kasus Patologi Infeksi Protozoa Tetrahymena spp pada Ikan Hias Guppy (Poecilia reticulata )
Abstrak: The study was aimed to explore the protozoan Tetrahymena spp infection in Guppy (Poecilia reticulata) fish, with intended to the morphology of parasites in tissue sections and the resulting tissue lesions. Sample of diseased Guppy fishes were used in the study. Observation of clinical symptoms of the Guppy were revealed lethargic, vertical swimming and impaired equilibrium. The fish organs were observed macroscopically and microscopically. The result of macroscopic observation showed that there were excessive haemorrhage and ulceration at skin particularly in the dorsal and lateral abdomen. Protozoan parasite in the skin, muscles and gill tissues were identified by histopathological examination using hematoxylin-eosin staining and positive responses to periodic acid Schiff staining. Study of protozoan morphology revealed a spherical shape pyriform with a narrow anterior end, have dimension in average 50.5 x 32.4 μm. The parasites cause skin erosion, and hemorrhage, muscular degeneration and necrosis along with gills edema. Severe fatty degeneration was presented in liver while there was edema and congestion in the intestinal mucosa. As these fishes were been cultured in the aquarium such disease is thought to be caused by the deterioration of water quality, feed contamination or a poor handling.
