Vulnerability Index Assessment for Mapping Ground Movements Using the Microtremor Method as Geological Hazard Mitigation

Various geological disasters, such as landslides and ground movements, occur annually in Srimulyo Village, Malang District, with varying levels of damage. Ground movements can affect structures built above, causing sinking, cracking, and collapse. Research into landslides and ground movements triggered by vibrations is generally conducted using the microtremor method, which has proven effective. This study uses the microtremor method to map the soil condition that is potentially prone to movement or landslides based on the observed soil vulnerability index. Data was collected using a TDL 303s Digital Portable Seismograph instrument; the measurement points were established in the form of a grid distributed across the research area, with a recording duration of approximately 45 minutes at each point. The analysis technique utilizes the Horizontal Vertical Spectrum Ratio (HVSR) based on the Fast Fourier Transform (FFT) principle. The study’s results found that the research location’s seismic vulnerability index varies between 6.5 and 16.5. Areas with high seismic vulnerability index values, specifically those with Kg>11.5, are scattered on the west, south, and southeast sides of the research location. Based on field observations, these areas are dominated by relatively thick sediment layers, leading to lower dominant frequency values and higher amplification values; consequently, the seismic vulnerability index in the southern region is also high.

Seismic hazard analysis using Deterministic Seismic Hazard Analysis (DSHA) Method: A case study in Southern Malang District, East Java

Indonesia is a country that has a high earthquake threat. The United States Geological Survey (USGS) recorded that Indonesia experienced 5,439 earthquakes with a magnitude of Mw 5. Geologically, Indonesia is located about 200 km from the subduction zone of the Indo-Australian and Eurasian plates. Malang Regency faces the subduction of the Indo-Australian and Eurasian plates. Earthquakes that occur in plate subduction areas will propagate in various directions, including to Malang Regency. Thus, Malang Regency, especially in the southern part, has a high earthquake threat. This study aims to calculate the earthquake threat using a deterministic approach. Earthquake threats can be calculated using the Deterministic Seismic Hazard Analysis (DSHA) method. This study obtained the Mc. Guirre and Donovan attenuation function. These two attenuation functions produce different Peak Ground Acceleration values. The calculations with the Mc. Guirre attenuation function has a range of PGA values from 38,76461 gals to 69,78215 gals. Meanwhile, the Donovan attenuation function calculation produces a range of PGA values from 41.97550 gals to 76.21376 gals. Based on the value of ground acceleration during an earthquake, Bantur, Gedangan, and Sumbermanjing sub-districts are the sub-districts with the highest earthquake threat level in Southern Malang Regency. Tirtoyudo Village, Tirtoyudo District, Malang District has a lower PGA value when compared to Gedangan District. However, the amount of damage to buildings in this subdistrict was much higher. Since the building structure in Tirtoyudo Village cannot withstand ground shaking due to the earthquake, there is damage to the structure of the building.

Plant diversity on coffee agroforestry land in the buffer zone of Bromo Tengger Semeru National Park in East Java, Indonesia

Abstract. Zayadi H, Hakim L, Sudarto, Batoro J. 2024. Plant diversity on coffee agroforestry land in the buffer zone of Bromo Tengger Semeru National Park in East Java, Indonesia. Biodiversitas 25: 1030-1036. Bromo Tengger Semeru National Park (BTSNP) is facing threats to biodiversity due to land transfer functions and sand mining in rural areas. Land use conversion and sand mining in rural areas near BTSNP and Perhutani are threatening biodiversity through activities like land degradation, deforestation, forest depletion, and global climate change impacting local agriculture. Coffee farms in Poncokusumo and Wajak have been abandoned, leading to a decline in coffee farming and other agricultural commodities. Coffee-based agroforestry systems have been implemented to address this issue and improve soil fertility and vegetation diversity. This research aimed to identify and analyze plant diversity in coffee agroforestry land in BTNSP. The study was carried out in January-December 2022 in the village districts of Poncokusumo Sub-district (Sumberejo) and Wajak Sub-district of Malang District, which borders directly with BTSNP, collecting flora compositions and classifying them based on growth rate. The study identified 27 orders, 38 families, and 71 species of plants in the coffee fields. The presence of various plant species in the coffee fields contributes to the ecosystem's stability and the soil's quality. This research highlights the importance of the agroforestry system in promoting biodiversity conservation and sustainable coffee farming in the BTSNP area.

Enhancing Tenure Security: A Case Study of the Social Forestry Scheme in the State Forestry Corporation, Malang District, East Java

The Social Forestry Program was a government initiative that yielded significant outcomes and provided unprecedented access and opportunities to the community. One notable change has occurred in the Perhutani area through a scheme known as IPHPS. This scheme provides long-term tenure security to forest farmers with higher returns than before. In addition, extensive experience in addressing tenure conflicts in the Perhutani area, a State Forestry Corporation (SFC), has prompted communities to apply for the IPHPS scheme. Therefore, this research aimed to investigate the dynamics of changes in access and assess their implementation using the concept of property rights as a framework. The results showed that the IPHPS scheme provided community groups the right to manage forests but needed more flexibility to decide on the use of resources. In addition, the management patterns regulation had a significant responsibility to restore forest conditions. Furthermore, this research proposed new rights, particularly management rights, for community groups to manage their forest resources up to the operational level and improve forest conditions. In addition, the absence of a management authority caused difficulties in achieving social forestry's objective of increasing local communities' role in managing their forest resources.

HEALTH COMMUNICATION STRATEGY FOR ENDING OPEN DEFECATION IN A RIVERSIDE COMMUNITY: A CASE STUDY IN MALANG DISTRICT, INDONESIA

Objective: Goal 6.2 of the SDGs emphasizes the importance of safe sanitation and ending open defecation in promoting health and well-being. This study analyzes health communication strategies for ending open defecation (OD) in a riverside community and identifies communication elements impeding the outcome.
 
 Methodology:. Using a qualitative approach, the data were collected through a forum group discussion (FGD), in-depth interviews, and observations. Fourteen people attended the FGD, including village government leaders, community and religious leaders, health cadres, people with OD habits, a midwife. Eight people were interviewed, including the head of the primary health center, the head of the environmental health division at Malang District Health Office, village government leaders, community and religious leaders, a sanitarian, and people with OD habits.
 
 Findings: The triggering method was combined with a customized communication strategy to promote OD behavior change. The study identifies challenges to achieving promotion objectives, such as villagers' distrust of some assisting team members due to a lack of training or workshops, the 'no subsidy' messages were ineffective because the local government granted latrine for the poor before, the use of face-to-face communication as a sole channel was found ineffective due to unreliable sources and a large number of participants, there is no regulation to sustain behavioral change.
 
 Suggestions: This study recommends training or workshops for community members who serve as the triggering team, encouraging self-built latrines through a financing plan and latrine models tailored to villagers' capabilities and preferences, combining face-to-face communication with villagers' preferred media, and issuing a regulation governing penalties for offenders.

THE RELATIONSHIP OF PUPIL SIZE WITH REFRACTIVE EROR IN METABOLIC SYNDROME AND NON-METABOLIC SYNDROME: POPULATION AMONG RURAL POPULATION IN MALANG

Purpose: This study aims to assess the relationships between pupil size and refractive errors in both metabolic syndrome and non-metabolic syndrome populations residing in rural areas of Malang. Methods: A descriptive study was carried out in 2019 across three villages in Malang districts. All attending participants underwent a comprehensive ocular examination, including pupil size assessment. Pupil abnormalities were defined as deviations from the normal diameter of 2-4 mm in bright light. Clinically relevant refractive errors included hyperopia (SphEq value ? 0.25 D), myopia (SphEq value ? -0.25 D), and astigmatism (cylinder ? 0.25 D). Blood samples gauged serum fasting glucose, high-density lipoprotein cholesterol, and triglyceride levels. Waist circumference, systolic, and diastolic blood pressure were measured. Metabolic Syndrome diagnosis followed the 2006 International Diabetes Foundation criteria. Participants were categorized into metabolic syndrome and non-metabolic syndrome groups. Results: The examination involved 953 participants, encompassing 944 right eyes and 942 left eyes. For the right eye, 434 eyes showed emmetropia, 252 exhibited myopia, 141 had hyperopia, and 117 presented astigmatism. Pupillary abnormalities were linked to astigmatism, but lacked significance (p = 0.893). The left eye results indicated 444 eyes with emmetropia, 244 with myopia, 138 with hyperopia, and 116 with astigmatism. Correlation with pupillary abnormalities yielded a non-significant p-value of 0.864. Pupil size outcomes in metabolic syndrome (499 eyes) and non-metabolic syndrome (454 eyes) were not significant (p = 0.649). Conclusion: Refractive error does not correlate with pupil size in metabolic syndrome and nonmetabolic syndrome.

Abstract. Setiawan Y, Hamdoen FM, Muhammad FN, Hata K, Tarno H, Wang J. 2024. Species composition of Bactrocera fruit flies (Diptera: Tephritidae) and their parasitoids on horticultural commodities in Batu City and Malang District, East Java, Indonesia. Biodiversitas 25: 305-311. Bactrocera Macquart, 1835 fruit flies (Diptera: Tephritidae) are among the most important pests in horticultural commodities worldwide, including horticultural crops in Indonesia. Trapping is suggested to control, eradicate, and suppress fruit flies. The presence of natural enemies is a very important factor in the indicators of agroecosystem balance. This study aimed to monitor the species composition of Bactrocera fruit flies and their parasitoids in several horticultural commodities such as apples, large chili, red guava, sweet citrus, and tomatoes in Batu City and Malang District. Trapping and host-rearing methods were used in this research. A total of 7,124 individuals of Bactrocera were collected using a Steiner trap baited with methyl eugenol. They consisted of six species: Bactrocera carambolae Drew & Hancock, 1994; Bactrocera cucurbitae (Coquillett, 1899); Bactrocera dorsalis (Hendel, 1912); Bactrocera verbascifoliae Drew & Hancock, 1994; Bactrocera papayae Drew & Hancock, 1994; and Bactrocera umbrosa (Fabricius, 1805). The B. carambolae, B. dorsalis, and B. papayae were the three predominant species collected using Steiner traps baited with methyl eugenol. Based on the host-rearing method, B. carambolae and B. dorsalis were found in red guava fruit. Only one parasitoid species, Opius sp., was found in red guava fruit. These results provide valuable insights into the distribution of Bactrocera on horticultural commodities in Batu City and Malang District and the potential challenges regarding parasitoid presence.

Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment

Abstract. Pasaribu DN, Rizali A, Tarno H, Priawandiputra W, Johannis M, Buchori D. 2024. Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment. Biodiversitas 25: 205-213. Fragmented natural habitats in human-modified landscapes play a crucial role in conserving biodiversity. Ants, as keystone species, are integral to terrestrial ecosystems, making it essential to comprehend the factors influencing their survival. This study investigates the impact of agricultural landscape composition and plant diversity enrichment (flowering plants) management on shaping ant communities in maize (Zea mays L.) fields. The research occurred in maize fields surrounded by other crops, semi-natural habitats, and housing areas in Malang District, East Java, Indonesia. The four agricultural areas were divided into control and treatment plots, considering landscape composition parameters, particularly Class Area (CA) and the Number of Patches (NP), measured within a 500 m radius. The landscape around the maize fields was characterized by manually digitizing land use. Six types of plant diversity enrichment were employed in this study: wild cosmos (Cosmos caudatus), white buttercup (Turnera subulata), sunflower (Helianthus annuus), long bean (Vigna unguiculata), ornamental bean (Arachis pintoi), and coral vine (Antigonon leptopus). The study was divided into the dry season (April-July 2022) and the wet season (September-December 2022). Ant sampling was conducted using pitfall traps and, based on generalized linear models, revealed that plant diversity enrichment management did not affect species richness, abundance, or composition of ants. Landscape composition positively influenced ant species richness but negatively impacted species composition, particularly the number of semi-natural habitat patches. Maize crop age also positively influenced ant species richness but negatively affected beta diversity. Wet season was also found to have a negative effect on beta diversity. In conclusion, the proportion of semi-natural habitats in agricultural landscapes and crop age contribute significantly to species richness and species composition of ants.
