Abstract

Cabai merah merupakan salah satu komoditas sayuran yang banyak digemari oleh masyarakat Indonesia baik sebagai bumbu dapur maupun pelengkap makanan. Tingkat produksi cabai merah masih berfluktuasi. Salah satu penyebabnya yakni adanya serangan Pepper yellow leaf curl virus (PepYLCV). Tujuan penelitian ini adalah mengidentifikasi secara molekuler penyakit PepYLCV dan melaporkan keberadaan penyakit tersebut pada pertanaman cabai di Kabupaten Gowa, Sulawesi Selatan. Pengambilan sampel tanaman cabai dilakukan di tiga kecamatan berbeda di Kabupaten Gowa dimana cabai banyak ditanam. Sampel yang diambil selanjutnya diekstraksi yang dilanjutkan dengan proses PCR, sekuen nukleotida, dan analisis filogenetika. Gejala infeksi virus pada tanaman cabai yang ditemukan pada tiga kecamatan di Kabupaten Gowa adalah mosaik kuning dan hijau, daun menggulung, melengkung ke atas dan/atau ke bawah, dan tanaman kerdil. Keparahan penyakit dan kejadian penyakit PepYLCV di Kabupaten Gowa masing-masing 78% dan 44%. Gejala infeksi virus pada tanaman cabai positif terinfeksi Begomovirus dan hasil analisis sekuensing menunjukkan bahwa virus tersebut adalah PepYLCV. PepYLCV di Kabupaten Gowa memiliki kekerabatan yang dekat dengan PepYLCV Bali. Hasil penelitian ini merupakan laporan pertama keberadaan PepYLCV di Sulawesi Selatan.

Abstract

Morphological characterization of Phytophthora isolates commonly was done on the basis of the colony and hyphal swelling characteristics, form, and shape of chlamydospore, sporangia as well as oogonia and antheridia. Molecular characterization was conducted using specific primer pairs Pal1 s and Pal2a for Phytophthora palmivora and universal primer ITS4 and ITS5 followed by sequencing of isolates. The virulence of Phytophthora palmivora isolates was tested on a cocoa pod of the Sulawesi2 clone. A total of 21 Phytophthora isolates were collected from Palopo, Gowa, and Pinrang Districts. Based on colony morphology and microscopic features i.e. chlamydospore, sporangium, and its papilla form, all isolates indicated Phytophthora palmivora. Molecular identification using a specific primer showed that all ten representative group isolates had the same band in size of 650 bp, whereas using universal ITS4 and ITS5 primers, all isolates generated one band in the size of 900bp. The sequencing result showed, that all isolates were placed in the group P. palmivora. The virulence of P. palmivora isolates on the Sulawesi2 clone revealed a varying degree of virulence, from less virulent to highly virulent. All isolates from Pinrang were classified as highly virulent because induced necrotic in more than 50% of the tested cocoa pod.

Abstract

Burkholderia glumae and Xanthomonas oryzae pv. oryzae are the primary causes of bacterial disease in rice, capable of reducing production and posing a threat to food availability. This research aims to assess the efficacy of a consortium of five bacteria contained in Mikrobat as bioactivators. The goal is to enhance rice yields, mitigate the severity, and suppress grain rot disease and bacterial leaf blight in rice. The research employed a split-plot design encompassing 12 treatment combinations replicated three times. The experimental setup involved two factors: the main plot consisted of rice varieties-Ciherang, Inpari 4, and Trisakti-while the subplots represented types of bioactivators-Mikrobat, EM4, Trichoderma asperellum, and a control. Results demonstrated Mikrobat’s positive impact compared to the control, with an average of 17.37 productive tillers and higher yields than other bioactivator treatments. Notably, Mikrobat exhibited 50.04% spikelets per panicle and a 1000-grain weight of 19.77 g. The severity of disease with Mikrobat treatment was notably lower than with EM4 and T. asperellum, featuring 4.20% for grain rot disease and 4.41% for bacterial leaf blight. This was significantly different from the control, which showed severity rates of 9.94% for grain rot disease and 7.75% for bacterial leaf blight. Among the three tested varieties, Ciherang demonstrated the best response, displaying higher resistance to both tested diseases. The varietal treatments did not significantly differ from each other. Although Mikrobat’s effects were not significantly distinct from EM4 and T. asperellum, its usage still reduced the severity and suppression of grain rot and leaf blight diseases

Abstract

The availability of adequate water is one of the key factors in supporting increased food productivity, especially in areas that have large agricultural potential such as the Warsansom Watershed (DAS), West Papua. This research aims to predict water availability in the Warsansom watershed using the Soil and Water Assessment Tool (SWAT) model. The SWAT model was chosen because of its ability to simulate hydrological processes, erosion and land use dynamics in a spatial-temporal manner. The data used includes rainfall, temperature, topography, soil type and land use patterns. The analysis results show that the average annual rainfall is 322 mm/year, with an annual average temperature of 26.49°C. The Warsansom watershed area is dominated by secondary dryland forest (78.69%) which contributes significantly to groundwater infiltration and recharge. Regional delineation resulted in 33 sub-watersheds with a total area of ​​144,280 ha, as well as 273 hydrological response units (HRU) which became the basis for identifying critical areas in water management. SWAT simulations reveal potential risks of surface runoff in areas with steep slopes (36.53%) that require conservation interventions to reduce erosion and sedimentation. This research recommends data-based strategies for optimizing water resource management, including improving irrigation infrastructure, developing cropping patterns that are adaptive to water availability, and mitigating the impacts of climate change. By utilizing SWAT simulations, it is hoped that food productivity in the Warsansom watershed can increase sustainably, supporting food security in the West Papua region

Abstract

This study aimed to evaluate the effect of aromatized thin-layer biopolymers on sensory perception in gel emulsions with spatial distribution of fat. An edible coating technique was used with Wijsman butter and cheese-cheese aromas to enhance fat perception without compromising other sensory attributes. Homogeneous gels with 20% fat content were applied with scented and unscented thin-layer biopolymers and then analyzed using the hedonic organoleptic method involving hardness, suppleness, color (transparency), and aroma parameters. The results showed that the scented thin-film biopolymer improved panelists' acceptance of fat aroma perception (score of 7.8), compared to the unscented biopolymer (score of 5.5). Panelists' acceptance of hardness, suppleness, and gel transparency did not differ significantly between the flavored and unscented treatments (values ranged from 7.1 to 7.9). This suggests that the addition of aroma can improve the perception of fat without affecting the physical quality of the gel. The use of aromatized thin-layer biopolymers can be an effective strategy to improve the sensory quality of low-fat food products, which is relevant in efforts to address the prevalence of overnutrition. This study contributes to the development of healthy food technology while maintaining consumer preferences for product texture and visuals.

Abstract

Maize production stability in drought-prone environments is crucial to ensure continuous raw material supply for the food industry. This study aimed to evaluate the interaction between mutant maize genotypes and different water availability levels to identify drought-tolerant genotypes during the vegetative growth stage. The experiment was conducted in a screen house at the Faculty of Agriculture, Hasanuddin University, using a factorial split-plot design with three replications. Water availability levels (60%, 80%, and 100% of field capacity) were assigned as main plots, while six maize genotypes were arranged as subplots. Analysis of variance (ANOVA) revealed a highly significant interaction (p ≤ 0.01) between genotype and water availability on root length, root volume, and flowering time. Under 60% field capacity, the Bisma 200 Gy genotype produced the longest root length (90.67 cm) and the highest root volume (116.67 mL), significantly exceeding the controls based on LSD at 1%. This genotype also showed lower leaf dryness and earlier male (51.94 days) and female (56.22 days) flowering. These findings demonstrate that Bisma 200 Gy exhibits enhanced drought tolerance through improved root development and accelerated flowering (drought escape), indicating strong potential as a stable maize raw material for water-limited environments.
