Abstract

The ship's driving system and propeller are components of the ship's propulsion device, and although they have been made in such a way and are strong, they will be damaged along with their service life. Damage to the propeller blades due to cavitation will have an impact, triggering noise and vibrations, and it will be the leading cause of decreased propeller thrust. Low ship propulsion efficiency increases fuel costs, making the ship unseaworthy and less efficient. Broken propeller blades when the ship is at sea threaten the safety of the ship and threaten the safety of the fishermen's lives. From the above conditions, the 2024 LBE-Collaboration PPM Program was held to provide counseling to members of the target fishermen group, "Kanja'tongeng", Borikamase Village, Maros Baru District, so that they can carry out maintenance on the ship's shaft and propeller independently in a good and correct manner. The evaluation results of activity achievements were carried out using the questionnaire method during the pre-test and post-test. Both showed a fairly adequate level of success. The number of participants who initially did not understand the extension material decreased from 67.86% to 12.05%. Likewise, there was an increased understanding of the material on ship shaft and propeller maintenance, as seen from the number of participants who initially understood it to an excellent level, from 11.90% to 39.16%. The achievement indicators above show that the PPM LBE-Collaboration 2024 program has been successful and is running effectively. This success, of course, not only increases the technical knowledge of fishermen about ship shaft and propeller maintenance, but will also improve aspects of ship safety and ship seaworthiness.

Abstract

Foot rot disease (FRD) on citrus plants is suspected to be caused by a Phytophthora spp., characterized by yellowish-brown stem discoloration and cracking or peeling bark. FRD spreads rapidly and can be fatal to citrus crops. The purpose of this study was to determine the intensity of FRD on pomelo (Citrus maxima) in Ma'rang, Segeri, and Labakkang Districts, Pangkep Regency. Symptomatic tissues were collected and examined microscopically at the Plant Disease Laboratory at Hasanuddin University. The highest disease intensity was observed in Ma'rang (27%), followed by Labakkang (21%) and Segeri (17%). The study also found that disease intensity was inversely related to light penetration under the canopy. Denser foliage with limited pruning resulted in lower light intensity and higher disease severity. The low intensity of light that enters under the trees canopy of pomelo plantations is affected by tree stands that have relatively denser crowns due to the infrequent pruning of less productive branches.

Abstract

Bactrocera musae is one of the most damaging fruit fly species affecting tropical fruit crops, particularly bananas. In Indonesia, this species is classified as an A2 Quarantine Plant Pest due to its economic impact and potential to spread into key production and export regions. However, updated information on its spatial distribution in South Sulawesi remains limited. This study aimed to map the occurrence and distribution of B. musae through field surveillance. Fruit fly specimens were collected using traps baited with methyl eugenol and installed across selected survey locations representing fruit-producing areas. Morphological identification was performed using standard taxonomic keys for Bactrocera species. The survey results confirmed that the distribution of B. musae in South Sulawesi is relatively extensive. The pest was detected in Makassar City and the regencies of Gowa, Takalar, Jeneponto, Bulukumba, Bantaeng, Sinjai, and Bone. These areas are characterized by the presence of tropical fruit crops, including banana, mango, guava, and papaya, which may serve as suitable host plants and support population establishment. The confirmed presence of B. musae in multiple regions indicates the need for strengthened surveillance, early detection programs, and quarantine measures. The findings of this research provide important baseline data for future pest risk analysis and policy development, particularly regarding pest status determination and preventive actions in South Sulawesi and other vulnerable regions. Further studies on population ecology, host interactions, and management strategies are recommended to support more effective control efforts.

Abstract

Conventional banana seedling propagation is often inefficient and time-consuming, so technological innovations are needed that can improve the speed and quality of seedling production. This study aims to assess the effect of liquid media-based Temporary Immersion Bioreactor System (TIBS) on the growth of planlets of three banana species. The research was conducted in a completely randomized design (CRD) involving two factors: media type (TIBS liquid media and solid media) and banana species (Barangan, Cavendish, and Kepok Tanjung), with three replications. The parameters observed included shoot emergence time, number of shoots per explant, number of leaves, and explant weight, which were analyzed using ANOVA and Honest Real Difference test (BNJ) at the 5% level. The results showed that TIBS liquid media significantly accelerated shoot emergence (11.89 days) compared to solid media (27 days). Barangan banana species produced the highest number of shoots (57.10 shoots) and the highest explant weight (33.44 grams), while the highest number of leaves was obtained in liquid media (68.40 leaves). The interaction between media type and banana type significantly affected all growth parameters. The conclusion of this study is that the liquid media-based TIBS system is able to improve the efficiency and quality of banana planlet growth, especially in the Barangan banana species, making it suitable for large-scale banana seedling development.

Abstract. Khaerana, Musa Y, Patandjengi B, Riadi M. 2026. Physiological and optical indicators of tungro severity across rice varieties with different resistance levels. Asian J Agric 10 (1): g100110. https://doi.org/10.13057/asianjagric/g100110. Tungro disease is a serious threat to rice production, with potential yield losses reaching 99% depending on the severity. This study evaluated the physiological response of rice plants to tungro infection, focusing on chlorophyll and anthocyanin content and light interaction characteristics. The study was conducted on six rice varieties with varying resistance levels (TN1, Inpari 13, Inpari 30, Inpari 36, Inpari 37, and M70D) using a factorial Randomized Block Design (RBD) with three replications. Tungro infection was established through controlled inoculation using two adult green leafhoppers (Nephotettix virescens) per plant and confirmed by PCR targeting Rice Tungro Bacilliform Virus (RTBV). Disease severity was assessed using a visual scale ranging from 1 (no symptoms) to 9 (severe stunting and leaf discoloration). Analysis of variance revealed a significant infection × variety interaction, indicating that physiological and optical responses to tungro differed among rice varieties according to their resistance level. The results showed that chlorophyll a content decreased by up to 42.8% in the susceptible variety (TN1), while chlorophyll b remained relatively stable (p>0.05). Anthocyanin content increased up to 2.7-fold in plants with a severity score of 9 compared to healthy plants. Tungro infestation reduced light absorption by up to 38.6% and increased reflection and transmission by 21.4% and 24.7%, respectively, indicating a response to mesophyll tissue damage. These findings suggest that a combination of physiological and spectral parameters can be used as an early indicator of tungro infection. This approach can potentially be developed as a rapid and non-destructive phenotyping method for breeding tungro-resistant rice varieties and to support precision optical sensor-based detection systems.
