Abstract

Malaria is a dangerous disease and is still a public health problem in Indonesia, caused by parasites of the genus Plasmodium and transmitted by female mosquitoes of the genus Anopheles. The purpose of this study was to analyze the risk factors for the incidence of malaria and measured the magnitude of the various risk factors that influenced the incidence of malaria in Nolokla Village, East Sentani District, Jayapura Regency. This study used a case control study to find out how far the risk factors included the physical environment, the biological environment and the socio-cultural environment on the incidence of malaria. The case group was all people who declared clinical malaria while the control group was those who were declared free of malaria. The number of samples in this study were 60 respondents, the case samples were taken randomly as many as 30 people and the control group was also 30 people were taken by matching method. The results of the bivariate analysis showed that there were four risk factors, namely the breeding site, the condition of the walls of the house, the presence of shrubs and the presence of Anopheles larvae, and there were six risk factors that had no effect on the incidence of malaria so they were not included in the follow-up test. From the multivariate analysis, it was found that the risk factors that influenced the incidence of malaria were breeding site (p=0.035, OR=3.143, 95%CI 1.066-9.267), condition of house walls (p=0.028, OR=4.500, 95%CI=1.094-18,503), presence of shrubs (p=0.006, OR=5,000, 95%CI=1,510–16,560), presence of Anopheles larvae (p 0.028, OR=3,500, 95%CI=1.112-11.017). The most dominant risk factor that may play a role in the incidence of malaria was the presence of shrubs (Exp=3.095).    Key words: malaria incidence; API; case control; Nolokla village.

Abstract

This study aims to analyze the effects of arbuscular mycorrhizal fungi (AMF) inoculation on the growth and yield of maize (Zea mays L.) as a solution to fertilizer shortages in Indonesia. The continuous use of inorganic fertilizers can degrade soil quality, making environmentally friendly alternatives, such as biofertilizers, necessary. The study observed the growth optimization of several corn varieties inoculated with AMF. The eight-month study was conducted in the Biology Laboratory at Cenderawasih University's Faculty of Mathematics and Natural Sciences using a pot culture method with three varieties of maize: regular maize (RM), sweet corn (SC), and butter sweet corn (BSC). Parameters observed included plant height, leaf number, and relative growth rate based on dry weight. The results showed that AMF inoculation significantly increased corn plant height by 21.56%, leaf number by 18.14%, and the relative growth rate by 1,425% at six weeks after planting. Butter sweet corn and sweet corn responded better to AMF inoculation than regular corn. The best results occurred when butter sweet corn was given 15 g of AMF inoculum per polybag.

Abstract

Tropical frontier regions such as Keerom Regency in Papua, Indonesia, face increasing pressure to expand food production under the National Strategic Projects (PSN) for food security. However, the absence of baseline data on soil fertility and water quality constrains the design of sustainable management practices. This study evaluated the temporal variation in soil chemical properties and aquaculture water quality to establish scientific benchmarks for site-specific interventions. Soil samples from chilli pepper (Capsicum annuum) farms were collected across resting, early growth, pre-harvest, and intercropping stages, while water samples from catfish (Clarias spp.) ponds were obtained during larval, grow-out, and harvest phases. Soil pH declined from 6.5 to 4.4, accompanied by reductions in total N, P, and K and a gradual rise in EC, indicating nutrient depletion and increasing acidity. In aquaculture ponds, DO levels decreased while Ammonium and nitrite accumulated during intensive feeding, suggesting excessive organic loading and incomplete nitrification. These results reveal critical limitations in both systems that reduce productivity and environmental resilience. The findings provide essential baseline data for nutrient management, fertilizer optimization, and water-quality control, forming a scientific foundation for future integrated agriculture–aquaculture (IAA) development to strengthen regional and national food-security initiatives in Papua.
