Abstract

Bondowoso located in a valley of Raung mountain roots in East Java, Indonesia. The eruption of Mt. Raung in 2015 not only cause loss of life, but also underlining the fact of unusual Snake Bite Cases (SBC), as recorded in the dr. Koesnadi Hospital. We conducted a thorough analysis of the SBC in 2015 along with the survey on all the incident location in January to March 2016. This study represented an improvement on the population of venomous snake in the agriculture area, and reached the highest peak before the eruption. The presence of continuous vegetation at the edge of watersheds become green corridor that functioned as the movement track for snakes in order to avoid the volcano effect.

Abstract

Javan Munia is one of the common species of birds that found in west area of Indonesia (Sunda land). This species is endemic to Indonesia (Lombok, Bali, Java, and South Sumatra). The large population, especially during the harvest season makes this bird became a major pest for agriculture. This research aims to determine the adaptive behaviors of Javan Munia that become major reasons of widely spreads and the influence of these factors to the distribution. Observations made in Kalibaru, Banyuwangi, East Java, which is a mostly agricultural area. Any form of behavior in the territorial area (nesting and courtship areas) and range area (where colonize and feed) were observed periodically in the past 12 months. Sunbathing is known as a activity that undertaken by many species of birds, including the Javan Munia. This munia has specific mating and nest construction behaviour. The development of Javan Munia is very quickly, in 40 days, child will become a new adult. Javan Munia is very easy to adapt to the surrounding environment, including the used of oil palm (Elais guineensis) fiber and paper receipts as nest material. There are a possibility of invasive occurrence to the entire island of Sumatra by this species. It is quite possible because of the opening of oil palm plantations and settlements continue, until Aceh. The spread possibilty to east end of distribution (Lombok) can occur up to Nusa Tenggara Island, because of short distances between the islands and similiar vegetation circumstances.

Abstract

Hunting is the main support of life for the insectivores bird of the world. Through an understanding of Indigo Flycatcher behavior character, we compiled new information for the daily behavior of Indigo Flycatcher and Muscicapidae family in general. The study was conducted at 3 periods to interpret the effect of different seasons conditions: the first period (rainy season, 1 – 30 January 2015), the second period (dry season, 1-30 June 2015), the third period (transition season, 1 – 30 November 2015). The research station covers 3 research points (A=edge of the forest, b = garbage dump, c = dense forest. A canonical correspondence (CCA) was used to understand the significance of the interaction between the abiotic factors and season. Based on the observations, the transition of the season became the most preferred moment for Indigo Flycatcher. Indigo flycatcher hunts in a group, both singular and mixed. Point B is the most common location of Indigo Flycatcher hunting activity.

Abstract

Riparians are undergoing extensive reductions and changes in their natural composition into agricultural and urban area. The relationship between the vegetation distribution pattern and the riparian topography factor has been assumed to typically represent a biome-specific or vegetation-specific constant. This study aim is to analyze the vegetation distribution pattern with topography along Alista river in Dau District, Malang. We surveyed 3 stations that represent a zone of edge gradient between the river and the mainland: levee, mid-flood, and slough. We used the wetland classification (Obligate - OBL; Facultative Wetland-FACW; Facultative Upland (FACU); and Upland (UPL) for each species found from various sources. we observed that facultative upland plants have a broad dominance. Mid-floodplain and slough dominated by typical upland species. Although Levee widely consisted of by upland plants, this area has one distinctive obligate species: Equisetum. The presence of OBL species in the levee and mid-floodplain indicate the area is receiving more frequent floods than other areas.

Abstract

Bemisia tabaci, yang umum dikenal dengan kutu kebul, merupakan serangga hama yang dikenal luas, mempunyai dampak signifikan terhadap pertumbuhan tanaman, khususnya pada kedelai. Hama ini dapat menyebabkan kerugian panen hingga 80% dan juga berperan sebagai vektor virus tanaman sehingga semakin mengancam tanaman. Penularan virus oleh B. tabaci, seperti virus gemini, dapat menyebabkan kegagalan hampir seluruh panen. Penelitian ini berfokus pada isolasi nematoda entomopatogen dari 11 lingkungan berbeda, antara lain perkebunan kakao dan karet, ladang jagung, perkebunan kentang, perkebunan kopi, sawah, ladang kedelai, dan lapangan golf. Nematoda ini dibudidayakan dan kemudian digunakan dalam percobaan laboratorium untuk menargetkan B. tabaci, yang dikumpulkan dari habitat aslinya. Studi ini memantau tingkat kematian B. tabaci selama 96 jam. Hasilnya menunjukkan bahwa seluruh sampel nematoda yang diisolasi termasuk dalam spesies Steinernema spp dan berpotensi menginfeksi B. tabaci. Namun, efektivitas isolat ini berbeda-beda berdasarkan asalnya. Isolat Steinernema spp dari wilayah Bromo (kode N) diketahui karena kemampuan infeksinya yang tinggi. Hal ini menunjukkan nilai LC50 sebesar 356.874 JI/ml dan angka kematian B. tabaci sebesar 97,63%. Temuan ini mempunyai implikasi signifikan terhadap pengelolaan hama di bidang pertanian. Temuan-temuan ini menyarankan pendekatan yang berbeda untuk mengendalikan infestasi B. tabaci dengan mempertimbangkan efektivitas isolat nematoda dari berbagai lanskap. Nematoda Steinernema spp, terutama yang berasal dari Bromo (kode N), menjanjikan sebagai solusi pengelolaan hama yang ramah lingkungan. Selain itu, penelitian ini menyoroti pentingnya penggunaan isolat nematoda spesifik lanskap untuk mengoptimalkan upaya pengendalian hama. Kesimpulannya, isolat nematoda entomopatogen, khususnya Steinernema spp, mempunyai potensi untuk melawan B. tabaci. Penyesuaian strategi pengelolaan hama dengan kondisi geografis tertentu sangatlah penting. Penelitian ini memberikan kontribusi wawasan berharga bagi pengembangan pendekatan berkelanjutan untuk menjaga hasil pertanian dan menjamin ketahanan pangan.

Abstract

In Indonesia, horticulture is a crucial part of agriculture, heavily reliant on agrochemicals. This study in East Java's Jember and Bondowoso regencies compared conventional and organic farming methods, focusing on their effects on aquatic macroinvertebrates as bioindicators. Research included sites practicing conventional horticulture (cabbage, chili) and organic rice farming. Measurements of water current, pH, conductivity, dissolved oxygen, and temperature were taken, along with macroinvertebrate sampling. Significant differences were found in pH, conductivity, and water current, but not in dissolved oxygen and temperature. Organic farming showed higher macroinvertebrate diversity and lower dominance, especially the Baetidae family. While BMWP-ASPT and EPT scores were similar across methods, organic farming rated unpolluted in biotilik scores. Hierarchical cluster analysis, PCA, and CCA revealed factors influencing the ecological impacts of farming practices. The study underscores how different agricultural methods affect macroinvertebrate diversity, highlighting their role as environmental indicators. This reflects the diverse ecological impacts of agricultural management practices.

Abstract

Cocoa is an important commodity crop in Indonesia. However, current obstacles related to the problem of cocoa shell litter which is slow to decompose are an obstacle in plantation management. Therefore it is necessary to conduct research related to the exploration and identification of saprophytic fungi in cocoa pod litter. Samples of cocoa pod litter were taken at PTPN XII, while the isolation and identification processes were carried out at the Mycology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya. From the results of macroscopic and microscopic identification, nine isolates of saprophytic fungi were obtained consisting of seven genera, namely Candida sp., Penicillium sp., Fusidium sp., Rhizopus sp., Chepalosporium sp., Trichoderma sp.1, Trichoderma sp.2, Aspergillus sp., and Trichoderma sp. 3.

Abstract

This study explored the effectiveness of ethanol and methanol as attractants for controlling the coffee berry borer (CBB), Hypothenemus hampei Ferr 1867, a significant pest in global coffee plantations. The research aimed to assess the efficiency of these substances as attractant traps for CBB in Kaliselogiri, Banyuwangi, Indonesia. Using a single-factor randomized block design, the experiment involved nine treatments, each replicated three times, with modified PTE traps of 2 L volume set up at 1.5 m height. Traps were checked weekly to monitor CBB attack intensity before and after applying attractants. Statistical analyses including the Mann-Whitney Non-parametric test and Duncan’s test were used to examine variations across blocks and weeks. Abundance boxplot graphs offered descriptive insights. Over six weeks, 14,044 CBB’s were captured. The peak was in the third week, with a decline in the fourth, followed by a resurgence until the end of the study. The Mann-Whitney U test showed a significant p-value (p = 0.000; confidence level = 5%), confirming the effectiveness of the attractants on CBB. Of the treatments, K6 (Ethanol: Methanol = 2:1) was most effective. Ethanol and methanol proved to be efficient lures in CBB management traps, with ethanol particularly effective in larger compositions, suggesting its wider application. These results support the use of attractant-based strategies for CBB control and highlight the importance of ethanol and methanol. Further research is needed to optimize attractant compositions and assess long-term impacts on CBB populations and agroecosystems. The ecological consequences, including potential effects on non-target species and overall sustainability, warrant further investigation. In summary, this study advances CBB management through attractant-based traps, emphasizing the importance of ethanol.
