Judul: System modelling for development of essential oil agro industry using cluster approach
Abstrak: Agroindustrial clustering of essential oil is a development strategy through grouping industries or institutions, which has vertical and horizontal relationship, complementarities and commonalities in increasing the competitiveness of essential oil agroindustry. The formulation of its trategic planning is complex because stakeholders and institutions involved in this industry have their own preferences and resources. Therefore, system approach is needed to make it effective and comprehensive.

Judul: The design of empowerment of rural communities in agroindustry cluster of essential oils (case study: patchouli oil)
Abstrak: Patchouli oil is an essential oil commodity in Indonesia. A research on design of empowerment on rural communities in agroindustry cluster of essential oils has been conducted using system approach which aim was to establish its Decision Support System (DSS). The research produced DSS model of comprehensive essential oil agroindustry from farming and small refinement industry that harmoniously accommodate the needs of stakeholders and should be effectively used by the decision makers facing dynamic changes and information updating. Analytical tools such as cost analysis, Fibonacci technique, OPTSYS programme, IPMS (Integrated Performance Measurement System), FGD (Focus Group Discussion), AHP (Analytical Hierarchy Process), pairwise comparison and ISM (Interpretive Modelling System) were applied. The DSS software called PAP-Klaster that consist of several modules, namely the feasibility analysis of farming and post harvesting with a result of being feasible (Farming IRR= 14.6%, B/C ratio= 1.35; Small refinement industry IRR= 47.99%, B/C ratio= 1.69), selling price equilibrium of patchouli and patchouli oil which provide a proportionate profit margin (selling price equilibrium of patchouli: Rp 1 483/kg, selling price equilibrium of patchouli oil: Rp 396 770/kg ), performance measurement of farming and post harvesting in agroindustry cluster system resulting to the identification of 16 Key Performance Indicator (KPI) from 56 Performance Indicator (PI). Conceptual model of agroindustry cluster of essential oils that end result could arrange institutional engineering and found key elements such as sector of society, needs, constraints, goals, possible changes, benchmarks, activities needed for action planning and institution involved. Institutional engineering resulting Jejaring Usaha PAP-Klaster and Forum Lintas Pelaku Klaster Agroindustri Minyak Atsiri. This model was verified through case study on patchouli oil agroindustry in Kuningan and Brebes regency. Empowerment of rural communities in essential oil agroindustry not only improves the welfare of agroindustry entrepreneurs but also will improve the welfare of patchouli plant growers.

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.
