Abstract

This study aims to explore and test the quality of Trichoderma spp. local from the rhizosphere of apus bamboo (Gigantochloa apus) against Fusarium spp. wilt disease both in vitro and in vivo in tomato. This research was conducted in the Keerom area, Jayapura, which is one of the centers of food crop production and horticulture in Papua. The data obtained from this study were analyzed by comparing the inhibition of three Trichoderma spp. isolates (Trichoderma sp. 1 isolate, Trichoderma sp. 2 isolate, and Trichoderma sp.3 isolate) against Fusarium spp. The results of the antagonist test showed that the isolate of Trichoderma sp.3 had the highest inhibition (80.56%) against Fusarium spp., followed by Trichoderma sp.2 (66.84%) and Trichoderma sp.1 (27,62%). The implication of this study is that Trichoderma sp. 3 has high potential as an APH in the control of Fusarium spp. wilt disease in tomato plants. The use of Trichoderma spp.-based APH can be an effective and environmentally friendly alternative in reducing the use of chemical pesticides and maintaining the balance of the agro-environmental ecosystem.

Abstract

Plant diseases result from the interaction of virulent pathogens, susceptible host plants, and favorable environmental conditions, often indicated by the appearance of growth abnormalities, referred to as symptoms, across various plant parts.This study aims to identify the species of Intsia plants affected by diseases and to determine the types of fungi responsible for causing diseases in Intsia sp. This research involved field surveys, observations, and sampling of pathogenic fungi, followed by fungal isolation and identification at the Mycology Laboratory and the FMIPA Biology Laboratory, Cenderawasih University, Jayapura. The methods employed included site surveys, sampling, isolation of pathogenic fungi causing diseases in Intsia sp. , identification of disease-causing fungi, and pathogenicity testing. Based on observations, the Intsia species affected by diseases were Intsia bijuga and Intsia palembanica. Four fungal species were identified as disease-causing agents in Intsia plants, including Aspergillus sp., Penicillium sp., Fusarium sp., and Mucor sp., along with one unidentified fungal species.

Abstract

Cocoa (Theobroma cacao) pod rot fungi  have various types. In general, cause cocoa pod rot  are fungi of the species Fusarium sp, Rhizoctonia sp, Phytium sp, Colletotricum sp, Amerosporium sp, Phomopsis sp and Phytopthora sp. Various species of fungi that can rot cocoa pods have high similarity in morphology characters even though the treatment for each species of fungi is different. This problem occurs in the people's nucleus cocoa plantations in the Yapsi district, Jayapura, Papua province. Samples of cacao pods infected with the fungus were taken and the isolates obtained were reinoculated into uninfected cacao pods. Isolates showing dominant infectivity were taken and identified molecularly. Identification was carried out by creating DNA barcoding by sequencing the Internal Transcribed Spacer (ITS) region of the 18SrDNA marker gene from the fungal isolates SP4DYAPSI-1, SP4 DYAPSI-2, SP3DYAPSI-1 and SP6DAUN3. Sequencing data in the form of isolate fungi DNA barcodes were analyzed with the ClustalX program analyses. The resulting phylogenetic tree construction shows that the four isolates are related to the fungus species Fusarium solani with a nucleotide similarity index above 95%. This shows that the cause of damage to cocoa pods in the Yapsi area, Jayapura, Papua, Indonesia is the fungus Fusarium solani.

Abstract

Rumpon is an environmentally friendly and highly effective fishing tool. Fishermen in the Jayapura city are skilled in capturing small pelagic fish, but they often have to search fish in constantly shifting and disorganized locations. This is due to a knowledge lack in determining the right fishing grounds. Another constraint is that Hamadi fishermen lack sufficient basic knowledge about the proper, correct, and environmentally friendly construction of rumpons. Factors influencing this situation include the lack of support from relevant agencies, limited knowledge, and the capital required for rumpon construction. Therefore, training in rumpon construction for fishermen in the Hamadi District is crucial. The aim of this training is to enhance the understanding of local fishermen in the city of Jayapura regarding the role of rumpons as fishing aids and environmentally friendly rumpon construction techniques. The methods used in this training include observation, the delivery of material on rumpon construction techniques, and focused group discussions (FGDs). From the results of the activities, local fishermen in the Hamadi District, Jayapura, have varying levels of understanding. However, based on the analysis, it is evident that the percentage of understanding among the fishermen before and after the training is significantly different. Before the training, the average level of understanding among fishermen was low in terms of rumpon construction steps. After the pre-test, about 60.625% of fishermen answered incorrectly, while only 39.375% answered correctly. However, after the training, a significant change occurred, with approximately 92.125% of fishermen answering correctly, and only about 7.875% answering incorrectly.

Abstract

Repang Muaif Village, located in Nimbokrang District, Jayapura Regency, has significant potential for ecotourism development. However, limited access to clean water remains a major challenge for the management of Isyo Hills Ecotourism. Surface water used by the community contains high levels of organic matter and sediment, resulting in murky water that affects visitor comfort. This community service project aimed to develop and implement a simple water filtration unit using gravity-based filtration techniques. The methodology included site surveys, technical training, and community-based construction of the filtration system using locally available materials. The results show significant improvement in water quality, particularly in turbidity and pH levels. The treated water became clearer, and its pH increased from 6.2 to 7.1, meeting acceptable standards for non-drinking daily use. This technology is easy to replicate and maintain, empowering local communities to sustainably manage clean water resources in support of eco-tourism activities.

Abstract

The environment faces many important issues that must be resolved immediately because they can negatively impact various forms of life, including humans. One common problem is the lack of maintenance, which leads to the decline of forest areas and marginal land. Since plants play a vital role in human life, conservation and reforestation efforts are necessary to restore the land and maintain the balance of life. This activity aims to raise environmental awareness among the younger generation through productive plant-based greening activities. Methods include focus group discussions (FGDs), planting on marginal land, and evaluation. This activity was carried out in Jayapura City in collaboration with the Papua Environmental Council (MLH) and the Papua Province chapter of the Muhammadiyah Student Association (IPM). The practical planting activity with productive plants took place on barren land in the Koya Barat area of the Muhammadiyah apartment complex in Jayapura City. Based on the evaluation results, it was found that, before the activity, participants had a good understanding of basic environmental knowledge, reaching 96%. This increased to 100% after the activity. Understanding of protecting the environment and biological resources increased by 26.16%, rising from 76.44% to 96.44%. Understanding of land rehabilitation and reforestation increased by an average of 79.17%, rising from 57.33% to 97.33%. These increases are significant because they demonstrate substantial improvement. Participants responded positively to the material, with 84.8% strongly agreeing and 15.25% agreeing
