Judul: A design model of crisis management simulation in an agroindustry enterprise.
Abstrak: In the industry, crisis is often defined as a sudden big trouble threatening the achievement of the organization’s central goals- profits, growth and survival, or endangers its reputation. This research aims to develop a crisis management model for agroindustry using an integrated expert system or knowledge based system, economics analysis and fuzzy logic. The model, CrismanSoft (crises management software), detects impacts and probabilities of internal crises, provides early warnings and recommendations to solve the crises. This research is limited to the core crises within the agroindustry companies which related to the exploitation to change risks into profits. Core crises include the crisis caused by labor strikes, permits revocation, and shortages of raw materials, which happen because of technological failures, confrontation or conflicts, malevolence or terror, managerial failures and other threats to the company. The scope of this research is internal crises in an agroindustry caused by raw material and product, technological, social or financial failures.

Judul: Design of intelligence system for tapioca agroindustry development strategy with Chaos theory approach
Abstrak: Chaos could occur anytime in agriculture sector, and that some occurences will be predictable and some will not, so it needs early warning system that could detect early chaotic conditions and take action for crisis recovery. Tapioca agro-industry turbulence condition was characterized by decreasing ability of the industry in production and business functions. Tapioca price and material supply was identified as key crisis factors in tapioca small scale agroindustry. This research was aimed to design early warning system for tapioca agroindustry. The expert management system was established as controlling tools through formulating policies for managing crisis due to chaotic situation. The output of this research was computer program, called “Simak-Chaotica” which consists of submodels: 1) the chaos existence test, 2) predictions in chaos key factor, 3) crisis signal analysis, and 4) crisis control policy Chaotic investigation with chaos theory approach for tapioca price and raw material supply identified by positive Lyapunov exponent and fractal dimension. Fractal dimension could determine another chaos component, embedding dimension to be considered as information about how many time lags were involed in Artificial Neural Network (ANN) forecasting. In the case study Lyapunov exponent value for the price of tapioca and raw material supply, respectively, were 0.1119 bits / week and 0.15656 bits / week. These properties indicate that the tapioca price and raw material supplies could not be predicted in the long term. Ttapioca price could be predicted within a period of 1 / 0, 1119 = 8.89728 approximately in 9 weeks, and the raw material supply in a period of 1 / 0, 15 656 = 6.34942 approximately in 6 weeks. Fractal dimension for the tapioca price was 1.05075 and 1.59616 for the raw material supply. Crisis signal analysis submodel was set up with threshold analysis, and supplemented with control management procedure. When tapioca price or raw material supply was evaluated at crisis level, then status alert would be presented as “Siaga”, “Waspada”, or “Bahaya”. Strategy and policy alternatives were formulated by Issue Management Technology (IMT) and OWA. Rule base was used to select policy alternatives for chaotic management. Agroindustry will cooperative body will ensure the long term cassava business resistance to the crisis. It was community based institution that relies on social cohesion and collective efficiency.

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.
