Judul: Potensi Transmisi Malaria Falciparum Nusa Tenggara Barat Menggunakan Metode Kapasitas Vektor
Abstrak: Malaria falciparum is a vector borne disease that still exist in some area at West Nusa Tenggara Province (NTB), even prevention malaria programs have been done by the government. This ressearch corelate climatic factor i.e air temperature and rainfall with incidence of malaria falciparum transmission. A surveillance has been conducted during March-Augustus 2009 in Kayangan Sub district, North Lombok district, West Nusa Tenggara Province. The objectives was to identify the vector and parasite bionomic which could be used as a baseline data for the implementation of malaria elimination programme and implementing the vektorial capacity method as a new concept on malaria outbreak prevention. The results of the surveillance on both transmission potential of malaria falciparum disease and population of parasite showed that the index of malaria falciparum transmission potential was higher through wet season rather than in dry season so falciparum infections. It was found for about 7 % in the wet season and for about 3% was found through dry season. Other significant results were human biting from malaria vectors. Anopheles sundaicus was high through wet seasons otherwise Anopheles subpictus was high through dry season. The occurrence of human biting Anopheles subpictus highest in July with outdoor Man Hour Density (MHD) index of 5.50 and Anopheles sundaicus in April with indoor Man Hour Density (MHD) index of 0.95. The epidemic potential of malaria falciparum in Lombok island predicted will longer than Sumbawa island.

Judul: Climate suitability for anopheles spp. mosquitoes and malaria incidence in East Sumba, NTT
Abstrak: Malaria adalah penyakit yang ditularkan oleh vektor dan dipengaruhi oleh berbagai faktor, salah satunya adalah iklim. Faktor-faktor iklim di suatu lokasi, seperti curah hujan, kelembapan, dan suhu udara, dapat memengaruhi siklus hidup nyamuk Anopheles sp. vektor penular malaria. Penelitian ini bertujuan untuk menentukan dampak faktor iklim terhadap kejadian malaria berdasarkan kesesuaian wilayahnya terhadap kehidupan nyamuk menggunakan indeks ekoklimatik luaran model Climex 4.0. Data iklim yang dianalisis adalah data luaran model iklim yang dikoreksi dengan data observasi. Analisis korelasi Pearson dan POD (Probability of Detection) untuk melihat ketepatan hubungan antara angka kejadian malaria dan iklim. Peningkatan curah hujan, suhu udara rata-rata, dan kelembapan relatif dapat menyebabkan peningkatan kasus malaria karena memiliki hubungan positif. Nilai EI rataan untuk Kabupaten Sumba Timur berkisar antara 51-61, yang menunjukkan bahwa kondisi iklim antara tahun 2012-2021 sesuai untuk pertumbuhan nyamuk. Kecamatan yang rentan terhadap penyebaran penyakit terletak di daerah pesisir, sementara yang kurang sesuai terletak di daerah pegunungan. Curah hujan dan suhu memiliki korelasi tertinggi satu bulan sebelum terjadinya penyakit, dengan nilai korelasi masing-masing sebesar 0,68 dan 0,61; sedangkan curah hujan dan EI menunjukkan POD jeda waktu satu bulan dengan kejadian penyakit sebesar 0,69 dan 0,68. Nilai MoPI tinggi secara cukup konsisten terjadi ketika nilai EI dan curah hujan tinggi, sehingga dapat digunakan sebagai informasi periode penerapan upaya preventif mencegah penyebaran malaria., Malaria is a diseases transmitted by vectors and influenced by various factors, one of which is climate. Climate factors in a particular location, such as rainfall, humidity, and air temperature, can affect the malaria mosquito's life cycle. This research aims to determine the impact of climate factors on malaria occurrences based on the suitability of the regions for mosquito life using the ecoclimatic index output Climex 4.0 model. The climate data analyzed are climate model outputs corrected by observational data. The Pearson correlation and POD (Probability of Detection) analysis used to find the relationship between climate n malaria incidence. Increased rainfall, average air temperature, and relative humidity can lead to a rise in malaria cases due to their positive relationship. East Sumba has suitable conditions for mosquito growth during 2012-2021 due to having an EI value exceeding 51. Districts vulnerable to disease transmission are found in coastal areas. Rainfall and temperature have the highest correlation one month before the disease occurrence, with correlation values of 0,68 and 0,61; while rainfall and EI in a one month time lag show POD of 0,69 and 0,68. High MoPI values consistently occur when EI and rainfall values are high, so that that it can be used as information on the period of implementing preventive measures to prevent malaria transmission.
