Dengue Hemorrhagic Fever (DHF) is an environment-based disease (physical, biological and sausage) that is widely found in tropical and sub-tropical regions whose transmission is through mosquito bites of Aedes aegypti and Aedes albopictus species. Efforts to prevent the transmission of this disease by breaking the mosquito breeding chain itself are by carrying out 3M activities (Draining, Closing, Burying) plus and suppressing other transmission factors so that it is closely related to behavior. The purpose of this study was to determine the relationship between dengue incidence to knowledge, the condition of the Water Reservoir (TPA) and the presence of Aedes sp mosquito larvae in the West Ring Health Center area of Bengkulu City. This research is a quantitativeresearch with a type of analytical research. The results showed that the three variables had a significant relationship with the presence of Aedes sp larvae, namely the level of knowledge with a p value of 0.044, the condition of water reservoirs with a p value of 0.03 and the presence of mosquito larvae with a p value of 0.035. While the most influential / most dominant factor is knowledge, followed by the existence of larvae and water reservoirs, with Odd Ratio values (1.399; 0.623; and 0.535).

Penataan ruang yang baik mengurangi risiko bencana tanah longsor sesuai dengan tujuan penataan ruang sebagaimana tertuang dalam Undang-Undang Nomor 26 Tahun 2007 tentang Penataan Ruang yaitu untuk mewujudkan ruang wilayah nasional yang aman, nyaman, produktif dan berkelanjutan. Perwujudan ruang tersebut seharusnya tertuang dalam dokumen-dokumen rencana tata ruang yang terkait dengan keadaan risiko terhadap bencana. Peningkatan aktivitas pembangunan membutuhkan ruang yang semakin besar dan dapat berimplikasi pada perubahan fungsi lahan secara signifikan. Bencana tanah longsor dapat terjadi karena alih fungsi lahan menjadi lahan terbangun. Penelitian ini bertujuan untuk menganalisis nilai pengurangan risiko bencana tanah longsor akibat adanya rencana tata ruang wilayah. Penelitian bersifat kualitatif yaitu menganalisis rencana tata ruang dan kuantitatif yaitu analisis pemetaan risiko bencana. Hasil penelitian menunjukan bahwa Indeks bahaya/ ancaman bencana tanah longsor pada skenario eksisting berada pada kelas “bahaya sedang” karena mengalami pegurangan, namun pada skenario RTRW terjadi peningkatan pada kelas “bahaya tinggi” Meningkatknya luasan kelas bahaya longsor terjadi di enam dari delapan Kecamatan di Kota Lubuklinggau. Indeks Kerentanan bencana tanah longsor tidak mengalami perubahan yang signifikan antara skenario eksisting dengan skenario RTRW dimana semua skenario berada pada kelas kerentanan sedang. Indeks kapasitas bencana tanah longsor pada indeks kapasitas daerah berada pada level 2 yang berarti bahwa daerah telah melaksanakan beberapa tindakan pengurangan risiko bencana dengan pencapaian-pencapaian yang masih bersifat sporadis yang disebabkan belum adanya komitmen kelembagaan dan/atau kebijakan sistematis. RTRW Kota Lubuklinggau mengakibatkan kenaikan risiko bencana tanah longsor dengan Nilai Pengurangan Risiko (NPR) < 0 umumnya berada pada penggunaan lahan eksisting hutan alam atau pada kawasan rencana perkebunan. Luas area yang termasuk ke dalam NPR ini adalah sebesar 5.306,53 hektar atau 69,07 % dari luas Kota Lubuklinggau. Sedangkan Nilai Pengurangan Risiko (NPR) = 0 berarti wilayah tersebut tidak mengalami perubahan risiko akibat adanya RTR umumnya berada di penggunaan lahan eksisting sama dengan penggunaan lahan rencana (RTRW) misalnya kawasan Taman Nasional Kerinci Sebelat, hutan lindung Bukit Cogong, hutan produksi terbatas Hulu Tumpah, dan permukiman. Luas area yang termasuk ke dalam NPR ini adalah sebesar 11.334,93 hektar atau 30,93 % dari luas Kota Lubuklinggau. Berdasarkan hasil penelitian tersebut disarankan peningkatan kapasitas bencana melalui peningkatan kapasitas daerah dan kapasitas kesiapsiagaan bencana.

Management of watersheds (DAS) is carried out to regulate the reciprocal relationship between natural resources in the watershed and humans in order to realize ecosystem sustainability and ensure the sustainability of the benefits of these natural resources for humans. This research was conducted in Padang Kedondong Village, Tanjung Kemuning District, Kaur Regency. The village was chosen because it is located in the Padang Guci watershed which is one of the priority watersheds. This research was conducted during April-May 2021. The results of the research that has been carried out are as follows: 1. The socio-economic indicators for the Padang Guci watershed have an average value of 2.05 (from an interval of 1 = bad to 3 = good), meaning it is included in good criteria (2 < x 3), 2. The people of Padang Kedondong Village in general have knowledge and awareness of ecology. Basically, with the existence of these resources, the community wants to get better results to improve welfare and pay attention to and increase the carrying capacity of the environment. 3. Currently Padang Kedondong Village is carrying out natural resource management functions/activities which include planning (planning) which is carried out by building a village vision, identifying and mapping village potential, identifying problems that occur in the development process, organizing which is held directly by the Village Head and assisted by village youths, implementation (actuating) with active participation from the community, and controlling is carried out by the Village Head. This indicates that natural resource management activities are going well and the community is able to manage natural resources in a participatory and independent manner. 4. At this time CBNRM in Padang Kedondong Village cannot be said to be good or not because it is still in process/underway which is expected to be able to balance the goals of community empowerment and natural resource conservation in the form of equity, empowerment by giving the community authority in making decisions, conflict resolution has never happened and it is hoped that in the future there will be no conflict between the community, knowledge and awareness in this case the community is able to preserve the existing nature wisely especially in land use , as well as protection of biodiversity (biodiversity protection) the public is prohibited from taking fish with poison and electricity. Whereas in the aspect of sustainable utilization of natural resources (sustainable utilization) results have not yet been seen because it is only being developed.

Bengkulu province area elevating from 0 m to over 1000 m above sea level possesses high rice germplasm diversity. To obtain salinity controlling gene(s) from those germplasm, it is required to determine a suitableprotocol. This research was objected to determine NaCl concentration to select Bengkulu rice landraces. The standard most salinity tolerant genotype used in this research was ’Kuning’, a local variety usually grown on tidal area of Seluma Regency for generations. The growing media was Yoshida nutrient culture supplemented with a series of NaCl concentration of 0, 2000, 4000, 6000, 8000 or 10000 ppm. Observation was done every 2 days to find out the response pattern of rice seedling growth on different NaCl concentration. NaCl stress level was determined at 90% seedling dead (LC90) at the eighth day. The results showed that the increase of plantheight was deceased at concentration of 6000 ppm. Based on the mathematical equation generated from the percent mortality data distribution, the LC90 was at 3910 ppm NaCl concentration.

Glyphosate is a widely used herbicide for minimum tillage technology because it effectively kills broadleaf and grass weeds. Mixing glyphosate with other herbicide that has a different mechanism, such as 2,4-D may increase control efficacy and prevent the evolved of resistant weeds. Research was conducted to obtain the effective dose of glyphosate and 2,4-D mixtures and to evaluate the effect of the herbicide mixtures on the growth rate and yield of sweet corn. Depression on summed dominance ratios (SDR) and increased number of dominant weeds were observed after the application of glyphosate and 2,4-d mixtures. The interaction of the herbicide mixtures was observed optimum at the doses of glyphosate and 2,4-D of 1.94 and 1.5 L ha-1, respectively, with maximum of net assimilation rates (NAR) at 4-6 weeks after planting of 0.0003617 g cm-2 days-1. Plant growth rates (PGR) and NAR were observed maximum by a single treatment of glyphosate at a dose of 1.5 L ha-1 which were 2.23614 and 2.23607813 g cm-2 days-1, respectively. Yield of sweet corn observed as fresh-weight of cobs was found maximum of 129.41 g with a single treatment of glyphosate at 2,018 L ha-1.

Bengkulu Province has many local rice germplasms that have adapted to specific areas. The germplasm has certain character advantages so that it is maintained by farmers. The characteristics of each germplasm need to be identified in order to improve the properties of the existing germplasm. This study aimed to determine the performance, to estimate the value of genetic parameters, and to determine the genetic relationship of local rice genotypes collected from four districts in Bengkulu Province. The results showed that the ‘Kuning Sulaowangi’ genotype was the earliest in maturity had the highest number of tillers amongst genotypes. Genotypes which have significantly the highest average component yields were ‘Kunig Air Dingin’ and ‘Impera’. Traits that have a high heritability estimated value were weight of 100 grains (91.046%) and grain weight per panicle (80.252%). The weight of 100 grains also has the highest genetic variability value. Thus increasing local rice production is possible. Based on the results of the analysis with the similarity coefficient of 55%, the local rice genotypes could be grouped into two groups. Group I consisted of 9 genotypes namely ‘Kuning Pendek’, ‘Humbur’, ‘Cantik’, ‘Pandak Kelabu’, ‘Cisadane Putih’, ‘Kuning Sulaowangi’, ‘China Abang’, ‘China Putih’ and ‘Impera’. Other genotypes were in Group II. Trait improvement can be done through hybridization between individuals of different groups. To develope early in maturity and high-yielding varieties can be done through hybridization of the ‘Kunig Sulaowangi’ and ‘Kunig Air Dingin’

Cayenne peppers (Capsicum annuum L.) are horticultural commodities with high economic value and increasing market demand, both for household consumption and large-scale processing industries. However, cayenne pepper productivity in Indonesia remains relatively low, partly due to the limited availability of fertile land. One potential solution to this problem is the utilization of marginal lands, including ultisols. Ultisols possess chemical characteristics that are less favorable for optimal plant growth, such as low pH, poor nutrient content, and high aluminum saturation. There fore, this study aimed to obtain information on cayenne pepper genotypes that can adapt well and produce optimally on ultisols. The research was conducted at the Experimental Garden of the Faculty of Agriculture, University of Bengkulu, from May to October 2023, using a Randomized Complete Block Design (RCBD) with three replications. Observed parameters included plant height, first dichotomous height, stem diameter, number of dichotomous points, total leaf area, shoot dry weight, stomatal density, days to first harvest, number of fruits per plant, fruit length and diameter, fruit weight per plant, and percentage of marketable fruits. Data were analyzed using ANOVA at a 5% significance level and followed by Duncan’s Multiple Range Test (DMRT) at the same level. The results indicated significant differences among genotypes in most growth and yield parameters. The genotypes ‘Iggo’ and ‘Lajang’ exhibited superior performance, with the highest dry biomass weight and the highest fruit weight per plant. These findings suggest that the ‘Iggo’ and ‘Lajang’ genotypes hold strong potential for cultivation on Ultisol soils to support sustainable national cayenne peppers production improvement.
