Rice Tungro disease is one of biotic constraint that can reduce yield potential of rice. Tungro disease viruses are transmitted from one plant to another by leafhoppers that feed on tungro-infected plants. The most efficient vector is the green leafhopper, Nephotettix virescens. Green leafhoppers (GLH) generally found in areas with high altitude and low temperature. However, GLH and tungro disease can be found in medium and low altitude areas. The aim of this study was to determine the abundance of green leafhopper, tungro disease incidence, and effectiveness of inoculum source in different altitude at endemic areas. Field observations conducted to observe tungro disease incidence and the density of GLH population. Moreover, greenhouse activities were conducted to examine the effectiveness of inoculum sources, including ratoon, spilled grain, weeds, and plants in the vegetative phase. The results showed there was no significant difference in the GLH population dynamics in upland areas represented by Garut and lowland areas represented by Purwakarta, both showed low population density. Ratoon, spilled grain, and plants in the vegetative phase were the effective inoculum sources to be used as host tungro viruses.

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is the major disease in rice plants causing considerable economic losses. The objective of the study was to evaluate the resistant International Rice Bacterial Blight (IRBB) lines against bacterial leaf blight and the identification of Xoo pathotype from Central Java Province as the basis recommendation of the resistant varieties assembly with the background of resistant genes to overcome BLB disease. The evaluation of Xoo isolates from 22 districts in Central Java Province on IRBB lines was conducted in the rainy season 2016-2017 using split plot with three replications. The main plot was 15 IRBB lines, while the subplot was 110 Xoo isolates. Among 15 lines of IRBB, there were 10 lines have functioned as pathotype examiner of Xoo. The results obtained 6 lines were reacted resistant, namely IRBB5, IRBB7, IRBB8, IRBB57, IRBB64, and IRBB66. The IRBB66 line can be used as a resistant elder for the assembly of BLB resistant varieties because it has a combination of pyramiding resistant genes that were effective against BLB in some areas of Central Java Province. Pathotype IX was only found and dominant in Pemalang. Pathotype X was obtained in six districts of Tegal, Brebes, Banjarnegara, Purbalingga, Purworejo, and Grobogan. Pathotype XII was the most dominant prototype in 15 districts. Assembling of resistant varieties with resistant gene backgrounds based on the existence of a specific Xoo pathotype in the field can reduce the severity of BLB disease.

Initial information on spore populations of pathogenic fungi is needed to anticipate opportunities for rice disease to develop in swamps and to take early steps in disease control efforts. Disease control by suppressing the initial inoculum and its rate of development has a high chance of success and is preventive. The purpose of this study was to obtain information on the diversity of fungal spore populations in the air using spore traps in the swamp rice agroecosystem of Central Kalimantan. The research was carried out in the 2021 planting season at the swamp rice production center, namely Blanti Siam, Central Kalimantan. The study of the diversity of the fungal spore population was carried out in a display location of 14 ha of rice varieties and 66 ha of rice demfarm. For the display of rice varieties, 14 spore traps were installed, while at the demfarm location, 22 spore traps were installed. Observations of spore traps were carried out 4 times starting from nursery/tillage and continued for each stage of rice plant growth. Identification of fungal pathogens was carried out based on the morphological characteristics of the spores/conidia with the aid of a microscope. The results of the identification of the spore trap on the display of rice varieties and rice demfarm obtained spores of Rhizopus sp., Helminthosporium sp., Fusarium sp., Pyricularia oryzae, Alternaria sp., Cercosporella sp., and nematodes. Helminthosporium sp. found to be very dominant in both locations. Pyricularia oryzae was obtained in very low quantities. This is related to the low rate of blast disease at the location of rice display and rice demfarm. Fusarium sp., Alternaria sp., Cercosporella sp., and nematodes were found to be very low in spore traps.

Amidst the challenges of digital literacy and information reach, this research examines the strategy of the Communication and Informatics Office (Diskominfo) of Ciamis Regency in enhancing public information services through the Helo Ciamis application in 2024. The primary underlying issue is the lack of socialization and digital literacy concerning the application's use. The study's objective is to describe Diskominfo Ciamis's strategy for improving public information services via the Helo Ciamis application. This research adopts a descriptive qualitative method, with data collected through literature review, structured interviews, and observation. The findings indicate that the implementation of Diskominfo Ciamis's strategy to enhance public information services through Helo Ciamis has not yet been optimal. Key obstacles include limited resources, insufficiently solid coordination, varying challenges in community digital literacy, evolving cyber threats, and the absence of structured user feedback mechanisms. To address these, Diskominfo has undertaken efforts such as budget adjustments, human resource capacity building, strengthening cross-sectoral coordination, implementing strict Standard Operating Procedures (SOPs), and developing direct feedback features within the application. The implications of this research highlight the importance of a comprehensive strategy that addresses socialization, capacity building, and feedback mechanisms for the optimization of digital public information services.

The multidimensional problem of homelessness in Ciamis Regency demands coordinated action from the Public Order Agency (Satpol PP), the Social Services Agency, and the Health Agency. This study analyzes the roles of cross-sector actors in this issue using Ansel and Gash's (2007) theory of collaboration, with four dimensions: Initial Conditions, Institutional Design, Facilitative Leadership, and Collaborative Processes. Using a qualitative case study approach, data was collected through interviews, observations, and documentation. Results are available, but partial and suboptimal. Initial understandings among actors vary. The institutional design remains poorly structured, with suboptimal formal coordination and disintegrated policies. Leadership from the Social Services Agency is crucial, but communication and prioritization remain challenges. The collaborative process is linear, lacking a sustainable and integrated program, and minimal joint evaluation. The study concludes that the institutional design needs to be strengthened through a permanent coordination forum, an increased leadership role for program integration, and improvements to the collaborative process to make it more integrated and sustainable. Recommendations include developing comprehensive policies, increasing budgets, and establishing a joint evaluation mechanism for more effective homelessness management.

Undang-Undang Nomor 20 Tahun 2008 tentang Usaha Mikro, Kecil, dan Menengah (UMKM) menyatakan bahwa UMKM perlu diberi lebih banyak kekuatan dengan menciptakan lingkungan yang membantu mereka tumbuh. Studi ini terutama melihat usaha kecil dan menengah di Kabupaten Pangandaran yang sudah berdiri dan berjalan tetapi operasinya belum berkembang, yang menyebabkan mereka merugi dan akhirnya tutup. Masih ada juga pelaku UMKM di Kabupaten Pangandaran yang tidak menggunakan metode pemasaran, branding, atau pengemasan. Selain itu, tidak banyak peserta UMKM di Kabupaten Pangandaran yang mengikuti berbagai kelas pelatihan. Tujuan studi ini adalah untuk menemukan dan mengevaluasi bagaimana Dinas Perdagangan dan Perindustrian, Koperasi, dan Usaha Kecil dan Menengah (UMKM) di Kabupaten Pangandaran bekerja untuk membantu UMKM tumbuh. Dengan menggunakan metode penelitian kualitatif, peneliti dapat menggambarkan, menjelaskan, mencatat, menganalisis, dan memahami peristiwa dan data yang ditemukan dalam penelitian ini. Cara pengumpulan data untuk tesis ini adalah campuran dari studi pustaka dan metode penelitian lapangan seperti wawancara dan observasi. Pada saat yang sama, peneliti mengolah data, menyajikan data, dan menulis kesimpulan untuk metode analisis data. Hasil penelitian menunjukkan bahwa Dinas Koperasi, Usaha Kecil dan Menengah, Perdagangan, dan Perindustrian Kabupaten Pangandaran memiliki rencana yang matang untuk mengembangkan Usaha Mikro, Kecil, dan Menengah. Namun, strategi tersebut belum ideal karena masih terdapat sejumlah tantangan, seperti kebutuhan peningkatan kualitas sumber daya manusia untuk mendukung pertumbuhan UMKM, kurangnya dana khusus untuk pemberdayaan UMKM, dan terbatasnya kemampuan pemasaran produk UMKM di Kabupaten Pangandaran.

This research is motivated by the village government's strategy in developing agricultural potential in Ciganjeng Village, Padaherang District, Pangandaran Regency which is not optimal. The purpose of this study is to determine the Village Government's Strategy in Developing Agricultural Potential in Ciganjeng Village, Padaherang District, Pangandaran Regency. The method used in this study is descriptive analysis. Informants are 7 people. Data collection techniques are literature study, field study (observation and interviews) and documentation. The author uses qualitative data analysis techniques through processing data from interviews and observations to draw conclusions so that they can answer the problems in the study. Based on the results of the study, it is known that the village government's strategy in developing agricultural potential in Ciganjeng Village, Padaherang District, Pangandaran Regency through five strategies with eight indicators studied is quite good but not optimal due to obstacles such as limited village budgets for the agricultural sector, low levels of education and skills of some farmers, and minimal access to modern agricultural technology and limited number and intensity of agricultural extension workers, limited farmer access to potential business actors to be invited to partner with and lack of farmer understanding of the importance of farmer institutions. Efforts include establishing partnerships with external parties, such as the Department of Agriculture and universities, to obtain technical assistance and assistance for agricultural programs. Increasing community participation by actively involving farmer groups in development planning meetings is also being undertaken. The village government is also striving to strengthen coordination with relevant agencies to ensure the sustainability of technical assistance and conducting intensive outreach and coaching to the community regarding the benefits of farmer groups and the importance of collaboration with business actors.
