Perception on health and exercise among indonesian older adults: a sequential exploratory study in javanese rural communities

This study aims to investigate the perceptions of health and exercise among older adults in rural Javanese communities in Indonesia. Through a sequential exploratory approach, the research uncovers diverse levels of knowledge regarding health and exercise among the rural population. There are 40 older adults from three different regency in Central Java Province participated in filling out the Global Physical Activity Questionnaire (GPAQ). Further qualitative analysis used 25 samples out of 40 through convenient method. Semi-structured interview is conducted to confirm results of questionnaire and explore their perception on health and exercise. Despite variations, a predominant belief emerges among participants regarding the significant health benefits associated with exercise. Analysis reveals that a considerable majority (87.5%) of participants meet the World Health Organization's recommended standards of >600 METs/week, primarily through work-related physical activities. However, there remains a notable disparity in the prevalence of physical activity during leisure time, particularly in engaging in sport-related physical activities. The accumulated METs score dominantly comes from work and travel-related activities. Qualitative study reveals that there are still few initiatives among older adults to adopt a healthy living through sports and exercise. Some believe that sports were never part of their culture. To address these findings, we urge for strategic interventions from stakeholders to enhance awareness among rural older adults about the importance of sports and exercise to enhance the overall well-being. This entails the implementation of health education programs and the facilitation of collective exercise activities at the village level. Keywords: health, exercise, older adults, rural communities, GPAQ

PsbA-trnH Intergenic Spacer profile of Wax Apple (Syzygium samarangense (Blume) Merr. & L.M. Perry) Cultivars

The fruit known as wax apple, scientifically named Syzygium samarangense (Blume) Merr. & L.M. Perry, is a well-liked agricultural product originating from Demak Regency in the Central Java Province. When it is difficult to distinguish between different forms of an organism, using DNA barcoding to authenticate the identity of species based on their DNA is an important way. The psbA-trnH intergenic spacer is a commonly used molecular approach to analyse the genetic characteristics of plant species. This study investigated the psbA-trnH intergenic spacer profile of wax apple cultivars from Demak regency. The investigation revealed that the psbA-trnH intergenic spacer sequences of the S. samarangense cultivars, namely Madu Thailand and Madu Deli Hijau, had lengths of 535 and 492 base pairs, respectively. Both cultivars demonstrate a greater nucleotide composition of deoxyadenylic acid (A) and deoxythymidylic acid (T) in comparison to deoxycytidilic acid (C) and deoxyguanylic (G). The genetic distance between S. samarangense ‘Madu Thailand’ and ‘Madu Deli Hijau’ indicates a very tight relationship, with a value of 0.000. The psbA-trnH intergenic spacer proved to be insufficient in differentiating the S. samarangense cultivars from Demak regency, mostly because to its low capacity to discern between the wax apple cultivars.

Landslide Susceptibility Mapping Using Weight of Evidence Method in the Purwanegara District and Surrounding Areas, Banjarnegara Regency, Central Java Province, Indonesia

Abstract The research location is in the Purwanegara Subdistrict, Banjarnegara Regency, Province of Central Java. According to the Geological Agency of Indonesia, this location is a landslide-prone area, and many landslides occur yearly. Therefore, it needs a landslide susceptibility map is basic information for landslide mitigation in this area. The parameters used in this research are slope, lithology, distance from structural geology, distance from the river, land use, and rainfall. Using six parameters, the weight of evidence (WoE) method was used to develop a landslide susceptibility map. This research aims to make a zonation of landslide susceptibility in this area. The data were collected by field survey and visiting some related institutions. The landslide data used are 85 landslide events in the last three years. All data was then randomly divided into two groups: 70% as model data sets and 30% as validation data sets. The map of every parameter will be overlaid to create a landslide susceptibility zone. The Area Under Curve (AUC) method validated the final map. The result shows that landslide susceptibility zonation can be divided into four zones: very low susceptibility zone, low susceptibility zone, medium susceptibility zone, and high susceptibility zone. The very low susceptibility zone is mostly located in the north, the low susceptibility zone is mostly in the north and south, the moderate susceptibility zone is in the middle, and the high susceptibility zone is in the middle of the research’s location. The validation results of the success and prediction rates using the AUC method show an accuracy value of 0.86 and 0.82, respectively. According to the validation result, both can be classified as very good.

Geology of the Kebasen Paleovolcano in Banyumas Regency, Central Java Province, Indonesia

Abstract The new interpretation on geology of Kebasen district in Central Java, Indonesia which is located in the middle parts of Sunda Arc indicates the existence of a paleovolcano. This conclusion is achieved through 1:25,000 geological mapping with a focus on volcanic facies, characterization of lithology types, mineralogy, and fossil analysis, to clarify its volcanic history and paleo-environment. Laboratory analysis works on representative rock samples are done using petrography and fossil identification on calcareous sedimentary members. Our research results conclude that Kebasen paleovolcano was a composite volcano with a diameter of about 8 km, elongated in NW-SE orientation, with Kebasen city located at the SW rim of the old volcanic edifice. The volcanic history and resulting volcanic rocks consisted of two contrasting volcanic stages. The first one was explosive caldera-forming eruptions that produced thick and partly welded pyroclastic rocks, dominated by pyroclastic breccia at the lower parts and finer tuff members at the upper parts. After caldera-forming eruptions, volcanic activity was followed by effusive eruptions of basaltic to andesitic lavas that covered the caldera floor. The lavas have abundant pillow structures indicating a submarine environment, intermediate to basaltic composition, and porphyritic texture, with plagioclase and pyroxene as the most abundant phenocryst minerals. Available rock geochemistry data demonstrate that lavas have mafic to intermediate compositions, with magma affinity at the transition of calc-alkaline to tholeiitic series. Results of geomorphological and lithology association analysis conclude that the research area was part of the central to distal facies of a paleovolcano complex, with the paleo depositional environment in the open marine environment. The results of fossil analysis on calcareous sedimentary rocks between volcanic layers indicate that the age of volcanism was Early Pliocene (N18) with the paleobathymetry transitioning from upper-middle bathyal to outer–middle neritic, which were parts of the continental margin. It is concluded that Kebasen paleovolcano is a newly identified submarine caldera-type Pliocene volcano within the middle parts of the Sunda Arc in Central Java, Indonesia.

Rock Mass Characterization and Slope Stability Analysis Inlet Portal of Jragung Dam Diversion Tunnel, Indonesia

Abstract Slope stability is a serious problem that academics are still looking into in terms of human safety, equipment, and structures along the slope. Failure on slopes happens for a variety of reasons, including rock physical and mechanical properties, discontinuity factors, slope geometry, and external variables like as rainfall and seismic activity. The research location was conducted on the Jragung dam diversion tunnel, administratively located in Candirejo village, Pringapus sub-district, Semarang, Central Java Province. The purpose of this study was to use an empirical and numerical method to investigate the impact of rock mass categorisation on slope stability. The RMR (Rock mass rating) method is used to characterize rock mass, and the SMR (Slope mass rating) method is used to measure slope stability. The numerical slope stability analyses were carried out with the help of Phase2 (Rocscience, Inc.). The results showed that the slope at the intake portal was class IV (poor), and that it was unstable utilizing the SMR technique. According to numerical research, the basic design cut slopes with a 51° inclination were found to be unstable even after strengthening. It was suggested that the slope geometry and support measures be adjusted even more. Modified cut slopes were found to be stable after the slope inclinations were changed from 51° to 27° and shotcrete and rock bolt reinforcement were added.

Impact of compost and biochar from agricultural waste on reducing cadmium concentration and mancozeb residue in soil

The negative impact of excessive exposure to agrochemicals in shallot cultivation causes environmental pollution and human health. Biochar has the potential to absorb agrochemical contamination. This research aimed to investigate the effect of providing compost and biochar from agricultural waste on land quality, reducing the concentration of heavy metal cadmium (Cd) and mancozeb pesticide residues in soil and products in shallot. The experiment was carried out in shallot fields in Ngurensiti Village, Pati Regency, Central Java Province. Four different treatments, including combinations of biochar and compost, were applied, along with conventional controls. Data were analyzed using the F test (ANOVA) and Tukey's test using the Minitab statistical program version 16.0. The research showed that using biochar made from sugarcane bagasse, rice husk, corncob, and compost helped more soil bacteria grow and lowered Cd and mancozeb concentrations. In addition, treatment with biochar from sugarcane bagasse waste showed a decrease in Cd and mancozeb concentrations and a more significant increase in bacterial populations compared to other treatments (rice husk biochar and corncob biochar). Although there was a slight increase in Cd concentration in shallot leaves post-treatment, Cd levels in shallot bulbs remained within safe limits. This study shows that using biochar and compost from agricultural waste effectively improves soil quality, reduces heavy metal pollution, and lowers pesticide levels to support sustainable agriculture and protect people's health.
