Judul: A Web-Based Decision Support System For Quality Of Biodiesel
Abstrak: The main objectives of this research is to create a model of decision support systems for small industrial biodiesel that can be easier for processors biodiesel to manufacture biodiesel in accordance with the standards. A web based decision support systems for quality of biodiesel has four models, namely the determination of the model that produces the best decision for biodiesel processing in accordance with the characteristics of raw materials, the calculation model needs an additional ingredient in the treatment process that produces the decision to the needs of the process, determine the model that produces biodiesel product quality decisions in accordance with quality standards, and model analysis on the incompatibility of biodiesel quality that generates suggestions for the user. Decision support systems programme using the method of decision tree and rules based. The main conclusions of this research is produces a web based decision support systems for quality of biodiesel output of the simulation system that aims to facilitate the processing of biodiesel, especially small industries in producing biodiesel and biodiesel can be produced in accordance with standard (SNI).

Judul: Agroindustrial risk management of palm oil-based biodiesel
Abstrak: Biodiesel is fuel generates from vegetable oils that have properties similar to diesel oil. The advantages of biodiesel compared to diesel is an environmentally friendly fuel because it produces much lower emissions (sulfur free, low smoke number) in accordance with global issues, higher cetane number (> 57) so that the combustion efficiency is better than diesel, lubrication properties of the piston engine; biodegradable, a renewable energy because it is made from natural materials, and improve the independence of fuel supply because it can be produced locally. The purpose of this research is to design the risk management decision support system for agro-industry development of oil palm-based biodiesel. The design methods used include: a) risk analysis of raw materials, processing, and marketing using a non-numeric ME-MCDM. Measurement and assessment of financial risks using risk criteria (coefficient of variation). Financial feasibility studies using the instruments: net profit, NPV, IRR, payback period, the BEP and the Net B / C ratio. Determination of objectives and risk management strategies using the rule-base. AHP is used to obtain an alternative value in the aspect of raw material procurement, processing, and marketing. ISM digunakam in institutional management. This research resulted in a decision support system that is useful to help decision makers in addressing the risk of agro-bio-diesel. Risk management model is designed in a decision support system (DSS) with the name "Biodiesel- RM", can be used by industrial users and investors in the field of biodiesel. SPK software development using Microsoft Visual Basic Version 6.0 yamg consists of three main components namely database management system, knowledge base management system and model base management system. Model base management system consists of 4 sub-model: risk analysis of raw materials, processing of risk analysis, risk analysis marketing, and financial risk analysis. Risks can be reduced through agro biodiesel biodiesel industry cluster approach, with fasilisator FKMKI Biodiesel (Forum biodiesel industry cluster management communication), which was formed and initiated by the community clusters and the formation of cooperative agro-industrial biodiesel supported by investors, financing institutions, universities and research institutions

Judul: Prevalence of Bird Lice on Rock Pigeon (Columba livia) in 99Wonderland Park, Selangor, Malaysia
Abstrak: Rock Pigeon (Columba livia) have coexisted with humans for thousands of years and are used for various purposes such as food and in sports. Rock pigeons may have the potential to be infested with a wide range of ectoparasites, which can have a significant impact on their life cycle. This study aims to measure the prevalence of Columba livia with bird lice in 99Wonderland Park, Selangor, Malaysia in the year 2020 and to ascertain the impact of bird lice on the health of these infested birds. Data were collected from clinical records for the month of January to December in the year 2020 from 99Wonderland Park, Selangor, Malaysia. Lice were identified in 42 of the 80 Rock pigeons examined so, the overall prevalence of lice infestations was 52.5%. The prevalence of ectoparasites was found to be higher in young Rock pigeons (60.4%) as compared to adult Rock pigeons (37.4%). Columbicola columbae (wing lice) and Colpocephalum turbinatum (body lice) are two species of lice that have been detected. Body lice were more prevalent in young Columba livia birds at 47.6% whereas wing lice were more prevalent in adult Columba livia birds at 16.7%. Most of the lice were found in the thorax and abdomen area followed by the head and neck area., Merpati Batu (Columba livia) telah hidup berdampingan dengan manusia selama ribuan tahun dan digunakan untuk berbagai keperluan seperti makanan dan olahraga. Merpati batu dapat terinfestasi dengan berbagai ektoparasit, yang dapat berdampak signifikan pada siklus hidup mereka. Penelitian ini bertujuan untuk mengetahui prevalensi Columba livia dengan kutu burung di 99 Wonderland Park, Selangor, Malaysia pada tahun 2020 dan untuk memastikan dampaknya terhadap kesehatan burung yang terinfestasi. Data dikumpulkan dari catatan klinis dari bulan Januari hingga Desember tahun 2020 dari 99Wonderland Park, Selangor, Malaysia. Kutu diidentifikasi pada 42 dari 80 merpati batu yang diperiksa sehingga, prevalensi keseluruhan infestasi kutu adalah 52,5%. Prevalensi ektoparasit ditemukan lebih tinggi pada merpati batu muda (60,4%) dibandingkan dengan merpati batu dewasa (37,4%). Columbicola columbae (kutu sayap) dan Colpocephalum turbinatum (kutu badan) adalah dua spesies kutu yang telah ditemukan. Kutu badan lebih banyak ditemukan pada burung Columba livia muda sebesar 47,6% sedangkan kutu sayap lebih banyak ditemukan pada burung Columba livia dewasa sebesar 16,7%. Sebagian besar kutu ditemukan di daerah dada dan abdomen diikuti daerah kepala dan leher.
