Production Of Mini Tuber Potato (Solanum tuberosum L.) Ppt4 Zebra With Aeroponic System Through The Addition Of Lighting Color Settings And Lighting Length

Potatoes (Solanum tuberosum L.) are carbohydrate-rich crops. Low potato productivity in Indonesia stems from farmers' inadequate access to quality seed potatoes. One solution to this issue is enhancing quality seed potato production, achievable through aeroponic systems. Lighting, whether incandescent or LED, can optimize potato mini tuber propagation in aeroponic systems. Research on lighting's effects on potato growth remains incomplete. This study aims to investigate how lighting color and duration affect mini tuber production of Solanum tuberosum L. PPT4 Zebra using aeroponic systems. Conducted in Jurangkuali, Bumiaji sub-district, Batu, the study employed a split plot design. The main plot consisted of lighting colors (WC): light yellow (WK), white (WP), and purple (WU). Subplots were lighting duration (LP) at 3 hours (LP 3) and 5 hours (LP 5), each replicated four times. Each replication comprised 8 samples, with 18 potato plant cuttings per population. Variables included plant height, stem diameter, leaf count, chlorophyll level, root length, tuber count, tuber diameter, budding seed count, and tuber weight. Data were analyzed using F-tests followed by BNJ tests at a 5% significance level. Results indicated no interaction between lighting color and duration. Purple lighting yielded the highest tuber count and weight, while 3-hour lighting duration yielded superior plant height, stem diameter, leaf count, and root length.

A Multicriteria Approach to Assessing Landslide Community Resilience. Case Study: Bumiaji Sub-District

Bumiaji Sub-District is located in a mountainous area with a high-risk level of landslides. Throughout 2017-2022, there were 45 landslide events affected physical, social, and economic damages. One approach to reduce disaster risk is building community resilience. This research aims to assess Landslide Community resilience in Bumiaji Sub-District. It is important to describe the characteristic of resilience level in each village. This research was done by using AHP to determine the weight of variables and indicators, then calculated with Baseline Resilience Indicators for Communities (BRIC) based on six variables: Physical, Social, Economic, Environmental, Community Capital, and Institutional. Data was collected by primary and secondary data. Primary data was collected by using interviews with experts from the government and the local community in Batu City, and secondary data was collected from the literature study. The results of AHP show that the highest priority of indicators is community preparedness, and the lowest priority is the number of health facilities. The weight of each factor was multiplied by the values of the indicators to assess the landslide community resilience index. The highest level of community resilience is Punten, caused by the high score in Physical, Economic, and Institutional aspects. The low level of resilience is Bumiaji and Pandanrejo Village. Both villages did not have regular mitigation programs to strengthen local communities, so the resilience level of community capital is low.

Landslide Analysis in Brau-Batu, East Java, Indonesia Based on Geoelectrical Resistivity Data

The Brau landslide area is about 40Ha. The Brau landslide area is administratively located in the hamlet of Brau, Gunungsari village, Bumiaji sub-district, Batu city, East Java. Hamlet of Brau is famous as a tourism area and because of dairy farm in Batu city. Topographically, this area is located in a hilly area with a range of topographical heights between 1067m to 1202m or has a topographical elevation difference of 135m. With such topography, it is not surprising that this area has a potential vulnerability to landslide geological disasters. As a precaution against further landslides, residents are planned to relocate to other safer places. However, considering that the Brau area is a source of economic livelihood for local residents, residents want to stay there. To convince and ensure the vulnerability of this area, a study related to landslide variables is needed. One thing that can be done is to apply technology that can provide subsurface information on this disaster risk area. Therefore, in this study, geophysical research was carried out using the geoelectrical resistivity method to obtain information on the subsurface conditions of the landslide field in this area. The research was conducted to obtain information on the stability of the subsurface landslide field. From 60 VES data arranged in 12 cross sections, information is obtained that 6 cross sections or 50% cross sections are in stable condition. The location with the stable condition of the landslide field is then recommended as a location for the construction of a relocation site in the landslide area of Brau.

Screening of quorum quenching activity of rhizobacteria against Pectobacterium carotovorum subsp. carotovorum

Abstract. Lestari SR, Choliq FA, Sektiono AW, Hadi MS, Aditya HF, Rahmadhini N, Kusuma RM, Setiawam Y. 2022. Screening of quorum quenching activity of rhizobacteria against Pectobacterium carotovorum subsp. carotovorum. Biodiversitas 23: 4336-4342. Quorum sensing (QS) is a mechanism for determining the virulence of the phytopathogenic bacterium Pectobacterium carotovorum. P. carotovorum carries out the QS mechanism with the chemical compound acyl-homoserine lactone (AHL) to signal and carry out its pathogenicity and virulence. The pathogenicity of P. carotovorum can be prevented through quorum quencher (QQ) activity derived from bacteria that degrade AHL compounds by producing AHL-lactonase. In the present investigation, AHL-lactonase-producing bacteria were isolated from the rhizosphere of carrot cultivation in Bumiaji Sub-District, City of Batu, East Java, Indonesia. The isolated bacteria were screened for quorum quenching activity. Out of thirty-seven isolates, 7 rhizospheric bacteria showed QQ activity against the Chromobacterium violaceum bioindicator. The hypersensitivity test on tobacco plants showed that, five strains SRL07, SRL09, SRL15, SRL21, and SRL35 did not cause a hypersensitivity response. The five isolates were able to suppress the virulence of P. carotovorum in carrot tubers. The 16S rRNA gene sequences of the five isolates had the highest similarity to Bacillus thuringiensis, B. subtilis, and B. cereus. The five isolates were detected to have the gene encoding AHL-lactonase (aiiA). The present study provides new information about the QQ activity of rhizosphere and its potential as a quorum quencher against P. carotovorum.

The data analysis methods used in this study are simple linear regression and partial test (T-test) through SPSS applications. The dependent variable is youth trust. The independent variable is youth satisfaction. The results showed satisfaction had a positive and significant effect on confidence in the T-test.

Effect Of Rice Straw Mulch on Surface Runoff and Soil Loss in Agricultural Land Under Simulated Rainfall

Installation of mulch on agricultural land, besides reducing weed growth, can also protect the soil surface from rain and erosion. This study aims to determine the effectiveness of rice straw mulch in reducing surface runoff and soil loss before entering the river. The experimental soil materials were similar to those in Sumber Brantas village, Bumiaji Sub-District, Batu. Runoff modelling utilized the Armfield S12 Rainfall Simulator - Advanced Environmental Hydrology System, with rainfall of 1 and 1.7 l/min. Land with rice straw mulch was compared to land without mulch. The land slope was adjusted to study area conditions, with mild (9%) and steep (15%) slopes. The three-Way ANOVA method was utilized for statistical analysis. In all the experimental runs, it was found that straw mulch effectively reduced the sediment yields that could enter the river area by more than 50%. The results of ANOVA analysis on sediment yield also showed that the significance value of the interactions between slope, rain intensity, and mulch usage was 0 (p<0.05). These results show that the difference in variations in these three factors determines the sediment yield that occurs. In the future, comparing straw mulch with other materials to cover agricultural land should be conducted.

Young Farmers and Digitalization: From Price Taker to Price Maker

Information technology has developed rapidly, particularly in the area of social media. Almost all groups in society now use social media in their day to day activities, and one group that has been greatly impacted is young farmers. Before this era, farmers had difficulty accessing information. This study aims to find out what benefits are obtained and obstacles encountered by the use of social media in farming activities by the young farmers. This paper is descriptive explorative by using a qualitative approach. The data collection technique itself uses in-depth interviews, observations, literature studies, and documentation. The research location was in Bulukerto Village, Bumiaji Sub-District, Batu City which was carried out from November to December, 2017. The informants were chosen because they already used new media to support their farming activities. The result is the use of social media in the agricultural sector is widely used by young farmers in order to increase revenue and to seek information. Even so, there are still a number of problems faced by young farmers when utilizing social media, namely those interested in buying and selling online for agricultural products are not as high as other products and about the trust. The advice that can be given is farmers must post photos of products on Instagram with good pictures and caption. They also can tag others to reshare and spread the product information.
