Abstract

[EFFECT OF MYCORRHIZAL BIOFERTILIZER AND CHICKEN MANURE ON GROWTH AND YIELD OF COWPEA (Vigna sinensis L.) IN ULTISOL]. This study aims to 1) obtain the interaction of mycorrhizal biofertilizers and chicken manure on cowpea in ultisol and 2) determine the best dose of mycorrhizal biofertilizers for the growth and yield of cowpea plants, also find the best dose of chicken manure on the growth and yield of string beans. The study was conducted in April 2019 at the experimental garden, Integrated Zone of the Faculty of Agriculture, UNIB, Kelurahan Kandang Limun, Muara Bangkahulu District, Bengkulu City. This study used a factorial Randomized Completely Block Design (RCBD) with two factors and three replications. The first factor is the administration of a dose of mycorrhizal biofertilizer, i.e., 0 (without mycorrhizae), 2.5 g/plant, 5 g/plant, and 7.5 g/plant. The second factor is the provision of chicken manure doses of 5 tons/ha, 10 tons/ha, and 15 tons/ha. Each experimental unit consisted of 25 plants with some sample plots of 5 plants. There is an interaction between mycorrhizal fertilizer 5 g / plant with chicken manure 5 tons/ha, which gives the best results on variable weight pod pods equal to 1.55 kg/m2 and pod weight of 15.46 kg/ha. The application of mycorrhizal biological fertilizer at a dose of 5 g/plant has good vegetative growth compared to other mycorrhizal doses. It shows the highest results based on the average number of flowers/plants and the number of pods/plants. Doses of chicken manure up to a dose of 15 tons/ha do not significantly increase growth and yield of cowpea.

Abstract

[CHANGE IN SOIL CHARATERISTICS AND PERFORMANCE OF UPLAND RICE VARIETIES IN COASTAL AREA AS AMENDED WITH BIOFERTILIZER AND BIOCOMPOST]. Dryland in the coastal area has good potential for the cultivation of upland rice to reach food self-sufficiency and the development of future agriculture. Low fertility of the land the area can be overcome by using appropriate technology such as the use of superior varieties, bio-fertilizers, and bio compost. This study aimeds to (1) determine chemical and biological properties of coastal land to improve the growth of upland rice (2) find out the growth of upland rice in the coastal area using low input technology and (3) obtain upland rice varieties with high adaptability to a coastal area environment. The experimental design used was a split-plot design with the main plot of 3 upland rice varieties, namely Inpago 10, Serantan, and Local Variety, while the subplots are were fertilizer inputs namely [double inoculant P solubilized microbial p (pf) + K solubilized microbially + N fixation microbial N], [double inoculant P solubilized microbial (fma) + K solubilized microbially + N fixation micarobia], [biocompost at a dose of 10 tons/ha], and [inorganic fertilizer recommended by BPTP ie 200 kg Urea/ha, 100 kg SP36/ha, 100 kg KCl/ha]. The results showed that the coastal area has the potential for the development of upland rice cultivation. Also, the double inoculants of biological fertilizers were able to increase plant nutrient uptake, soil biological characteristics, and the growth of upland rice as compared to controls. Specifically, the best treatment is produced by application of [double inoculant microbial solvent p (pf) + microbial solvent K + microbial N fixation] combined with upland rice Inpago variety 10.

Abstract

[THE EFFECT OF MICRO-COMPOUND FERTILIZER AND HUMIC ACID ON AVAILABILITY OF P AND  UPLAND RICE YIELD IN COASTAL LAND] Indonesia’s coastal areas are potential  for the  agriculture. However, coastal areas have poor physical, chemical and biological soil properties that unfavorable  to the growth and yield of plants. Upland rice is a food crop that can be developed on coastal land using  humic acid technology and micro-compound fertilizers. This study aims to determinate the effect  of micro-compound fertilizers and humic acid on phosphor availability and upland rice yields on coastal land. This research was conducted from August to December 2021 in Beringin Raya Sub-District Muara Bangka Hulu, Bengkulu City. Soil and plant analysis was carried out in the Soil Science Laboratory, Faculty of Agriculture, Bengkulu University. This research was organized in  Randomized Completely Block Design (RCBD) with 2 factors. The first factor is micro-compound fertilizer which consists of 3 levels, namely 0, 70 and 140 g/ha and the second factor is humic acid which consists of 2 levels, namely 0  and 8 L/ha. Each treatment combination was reploicated 4 times. The results showed that there was no interaction between humic acid and micronutrient fertilizer on the observed variables. The application of humic acid at 8 L/ha  increased phosphor available by 27.55%, the root colonization by 20.65%, the population of microorganisms by 14.77%, the number of productive tillers of 15.72% and the weight of the pithy grain per plant by 31.50% as compared to control. Also, the application of micronutrient fertilizer at 140 g/ha increased the  weight of 1000 seeds, the number of productive tillers, the pithy grains by 7.22, 18.53, and 27.77% respectively as compared control. It is recommended that the upland rice variety can cultivate in coastal land with the application of 140 g/ha micronutrient fertilizer combined with 8 L/ha of humic acid.

Abstract

Soybeans (Glycine max (L.) Merrill) are a popular food commodity in Indonesia, but domestic production is still insufficient to meet the demand. To increase production, planting superior varieties on coastal land could be a viable solution. Despite the challenging biological, physical, and chemical conditions of coastal land, nutrients such as phosphorus (P) are crucial for enhancing production. Typically, the phosphorus content in the soil is lower than that of nitrogen (N) and potassium (K), and the ability of soybean plants to absorb phosphorus varies among varieties. This research aims to compare the growth, yield, and phosphorus uptake of four soybean varieties on biocomposted coastal land. The study was conducted using a Randomized Complete Block Design (RCBD) with a single factor consisting of four soybean varieties: Wilis, Anjasmoro, Malika, and Detam 1. The results indicate that the Anjasmoro, Wilis, Detam 1, and Malika varieties exhibit similar responses in phosphorus absorption. However, the Anjasmoro and Wilis varieties demonstrate better adaptability compared to Malika and Detam 1, as evidenced by their superior growth and yield. This suggests that Anjasmoro and Wilis have a higher capability to adapt to the challenging conditions of coastal land. Therefore, these two varieties are recommended for cultivation in coastal areas to boost soybean productivity, ensuring the sustainability and stability of the national food supply.

Abstract

Selama ini kawasan pesisir yang terletak di Kelurahan Beringin Raya kurang termanfaatkan untuk budidaya pertanian dan sebagian dibiarkan menjadi semak belukar, meskipun sebagian besar masyarakatnya berprofesi sebagai petani. Hal ini karena kawasan pesisir memiliki tanah dengan karakteristik yang kurang mendukung untuk pertumbuhan komoditi pertanian. Oleh karena itu, diperlukan teknologi khusu agar tanaman bisa tumbuh dan berproduksi dengan baik di kawasan pesisir, salah satunya adalah apliaksi pupuk hayati. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan masyarakat mitra tentang pupuk hayati dan aplikasinya melalui penyuluhan dan pelatihan serta pendampingan. Luaran yang dicapai dalam pengabdian ini adalah meningkatnya pengetahuan Kelompok Tani Wanita Rezeki Bersama  tentang pupuk hayati dan aplikasinya terhadap tanaman kedelai. Selain itu, adanya kegiatan pengabdian mampu membuat anggota KWT berminat untuk menanam kedelai menggunakan pupuk hayati. Anggota kelompok KWT juga telah bisa mengaplikasikan pupuk hayati.

Abstract

This study investigates the spatial dynamics of social vulnerability to tsunami hazards in Bengkulu City by applying the BNPB (2012) framework as a national reference for index-based assessments. Five key social indicators: population density, gender ratio, poverty, disability, and age were analyzed using spatial techniques and secondary socio-demographic data to identify spatial disparities in vulnerability across sub-districts. The findings reveal that Teluk Segara and Ratu Samban Sub-Districts are the most socially vulnerable areas, driven not only by high population density and poverty but also by their low-lying coastal topography, direct exposure to the Indian Ocean, and limited evacuation accessibility. In contrast, inland sub-districts such as Selebar and Singaran Pati demonstrate lower vulnerability levels due to their higher elevation and greater distance from the coast. These spatial variations indicate that social vulnerability in Bengkulu City is strongly influenced by the interaction between socio-economic vulnerability and oceanographic conditions. The study emphasizes the importance of integrating social and oceanographic dimensions into tsunami risk assessments to better reflect site-specific realities and support more effective mitigation planning.  Teluk Segara and Ratu Samban Sub-Districts need to be a priority for targeted preparedness efforts, improved evacuation infrastructure, and the restoration of coastal ecosystems is essential to reduce tsunami impacts. The results contribute to advancing integrated coastal disaster risk management in Indonesia by reinforcing the need to link human vulnerability with coastal environmental processes to achieve sustainable and resilient coastal communities.
