Determinants of Sexual Abuse Prevention Knowledge among Children’s Schools in West Java Indonesia: A Cross-Sectional Study

Child sexual abuse (CSA) is a severe problem in Indonesia. Adequate knowledge in children about CSA prevention is essential so that children do not become victims. Lack of adequate children’s knowledge of the prevention of CSA may put them at risk for experiencing CSA. This cross-sectional study explores the association factors between knowledge and characteristics regarding the prevention of CSA. The study was conducted in Bandung Regency, West Java, Indonesia. Students from grades two to nine at two elementary schools were eligible for the study. Results showed that as sources of information associated with better knowledge of CSA prevention (p = 0.00), teachers and parents significantly contributed to CSA information. Multivariate analysis showed that teachers (OR: 33.479, 95% (CI: 4.467–250.912)) and parents (OR: 45.336, 95% (CI: 10.886–188.807)) significantly contributed as a source of CSA information among students. The findings are essential important implications for interventions intended at preventing CSA. Sexual education programs should be officially applied at schools for children with the support of their parents and teachers.

Cookeina tricholoma of West Java (Indonesia) Based on Morphological and Molecular Identification

The incomplete information on most reported macrofungi is one of the remaining challenges of taxonomic work in Indonesia. Cookeina tricholoma (Ascomycetes, Pezizales, Sarcoscyphaceae), otherwise known as cup fungi, is no exception. In this study, we report C. tricholoma from West Java, Indonesia. Fresh materials were evaluated using morphological and molecular analyses. The specimen was illustrated with macro- and microscopic features. Molecular analyses were performed using the internal transcribed spacer region. Cookeina voucher BO24423 was identified as C. tricholoma. The morphological characteristics of C. tricholoma BO24423 are cup-shaped, pinkish to reddish, and with prominent hairs. The phylogenetic tree analyses confirmed that our specimens were C. tricholoma with 99–100% bootstrap value. This study is the first contribution to the identification of C. tricholoma based on morphological and molecular evidence for Indonesia.

Advanced characterization of hydrothermal flows within recharge and discharge areas using rare earth elements, proved through a case study of two-phase reservoir geothermal field, in Southern Bandung, West Java, Indonesia

Rare earth element (REE) analysis is effective for tracing water–rock interactions and solute transport in geothermal and groundwater systems. This study aimed to clarify hydrothermal flows within recharge and discharge areas of a geothermal system. We selected a well-known high-temperature geothermal field with two-phase reservoir in Southern Bandung, West Java (Indonesia) as a case study target, and collected 31 river/spring samples and 8 well rock samples. The measured total REE series concentrations ranged widely in the water samples, i.e., rivers: 3.4–35 ppt, cold springs: 0.3–284 ppt, and hot springs: 1.4 ppt to 102 ppm. Enrichment of light REEs (LREEs) in the water samples was characterized more clearly by Post Archean Australian Shale normalization than by chondrite normalization. Speciation analysis derived the following interpretations: dissolved REEs in the river water originated from free ions or Ln3+ that are typically contained in near-surface groundwater, and the dominant components were carbonate (LnCO3+) and Ln3+ complexes in the cold springs and LnCO3+ complexation in the hot springs. Steam and gas condensation into less-oxygenated groundwater can be indicated by rich LnCO3+. Only one hot spring was interpreted as being directly connected with the reservoir by strong H2S condensation and LREE enrichment. The water of the other cold and hot springs probably underwent dilution, evaporation, and magmatic gas condensation through shallow, deep, and deep-perched aquifers, permeable zones, and a major fault within the recharge and discharge areas. REE results also suggest that the main constituents of the aquifers are carbonates and silicate minerals and hydrothermally altered lahars, andesitic lava, and pyroclastic flow deposits. REEs facilitate detailed interpretation of geochemistry facies in shallow–deep waters of a hydrothermal system. Finally, integration of the analysis results of REEs, major anions and cations, water isotopes, and strontium isotopes improved a conceptual model of groundwater flows and recharge–discharge interactions in aquifers feeding a geothermal reservoir.

Accident Prevention Program Prioritization Using Kepner Tregoe Model: Case Study of PT Pertamina EP Regional 2 Zone 7

Pertamina EP Regional 2 Zone 7 (PEP R2Z7), a section of PT Pertamina EP (PT PEP), the National Oil Company of Indonesia, is an upstream Oil and Gas Company that operates in West Java Indonesia. The company conducts high-risk activities in exploration and production to extract oil and gas. According to the accident historical data, 40 work-related accident cases occurred in PEP R2Z7 in the period from 2018 to 2021. Accidents are caused by multiple factors that require programs to prevent a similar accident. The established accident prevention program in the company is generated from all accident data in PT PEP working areas around Indonesia which consist of 14 Zone. Because of these conditions, the accident prevention program becomes out of focus and needs to be prioritized based on accident case data. Accident prevention program priority is determined by the combination of Kepner Tregoe Method and Pertamina DNV SCAT accident root cause. The combination method is used to describe the root cause of an accident case, identify the accident prevention program criteria, and relevant alternatives to accident prevention programs based on the accident historical data, and choose the alternatives. The alternative solution is consist of the enhancement of established prevention programs and proposed the new prevention program. Some of Established prevention programs are still relevant with the historical data in Pertamina Region 2 Zone 7 such as Iman Campaign or Strengthen Work in Progress (WIP) Assessment. Meanwhile, some of the new proposed programs are Task Observation/Safety Awareness Supervision or Buddy System work for high-risk job. The implementation of the alternative solution is embedded inthe Objectives Target Program (OTP) of Health Safety Security and Environment (HSSE) PEP R2Z7. The OTP contains the program purpose, detail program, the output and the evidence of the program, schedule, and progress monitoring of the program. The proposed alternative solution is expected to reduce the number of accident cases in PEP R2Z7.

The Application of Electrical Resistivity Tomography using Wenner-Schlumberger Arrays Configuration to Identify the Geological Structure in Kancah Warm Spring, West Java Indonesia

Kancah warm spring is located in the southern part of Tangkuban Perahu Volcano, in West Java Indonesia. This warm spring has a temperature 470 C and a pH of 3 and it is used as a source of water for nearby tourist attractions. This warm spring has a large discharge, with the source thought to be from subsurface water associated with Tangkuban Perahu Volcanic complex. Knowing the source and geological control of this warm spring is one way to further identify the Tangkuban Perahu geothermal system, especially its permeability. For that reason, this research aims to using Electrical Resistivity Tomography (ERT) method to identify the geological structure that controls the appearance of geothermal manifestation using the resistivity method with Wenner – Schlumberger arrays configuration. The study starts with lineament study using DEM to identify the structure in surface and then determine the geometry of subsurface geological structures are using the electrical resistivity tomography (ERT) method using the Wenner - Schlumberger configuration. with a length 320 meters of each line and the electrode spacing is 10 m. The results of the interpretation of satellite images show that there is a lineament which is interpreted as a fault structure with a NE-SW direction that is right at the location of the discharge of the warm spring. There are 3 - 4 faults identified in each profile, some of the faults identified beneath the Kancah spring and may controlled the warm spring. These faults are a permeable that flows hydrothermal fluids from the subsurface to the surface in the form of warm spring..The lithology beneath of Kancah warm spring are dominated by breccia pyroclastics, clays, and a small amount of andesite igneous rocks.

The Millennial Farmers' Interest in Succeeding the Family Agriculture for Hydroponic Application in Garut District, West Java Indonesia

The interest of farmers' daughters and sons to become farmers has currently been very low, although productive age population is more dominant (62%) than other age groups. Low young villagers to choose the agricultural world is caused by many factors, negative stigma of farmers due to dirty, low income, and so on. A study regarding the millennials' to pursue parents' careers as farmers was performed in several villages around Tarogong Kidul District, Garut Regency. This survey study through interviews was conducted on April – June, 2021 with the aims of describing the youngsters' interest level to continue the family agriculture activity, the influenced factors, and finding strategies to increase the youngsters' interest level to continue the family agriculture activity. Data were collected from 54 respondents of 105 millennial farmers based on the Slovin formula with 10 percent error. Data collection was performed directly using closed questionnaires which have been assessed its validity and reliability. Data were analyzed descriptively to explain the variance of each variable, while double linear regression analysis was used to analyze the influenced factors. The study results showed that all independent variables influenced significantly the millennials' interest level with the R-square value of 0.580. The influence coefficients of each variable were formulated in an equation of Y = 82.385 + (0.898) X₁ + (0.448) X₂ + (0.269) X₃.

Comparison of coastal vulnerability assessment for Subang Regency in North Coast West Java-Indonesia

Coastal vulnerability is a spatial concept that can contributes to decision-making processes in managing the coast. Our study aims to compare and evaluate the coastal vulnerability index (CVI) and the weighted CVI (CVIw) along the Subang Regency coastline in northern part of Java Island-Indonesia. We use coastal parameters: coastal relief, morphology, shoreline change, tidal range, sea-level change, wave height, land subsidence, and land use. Then, vulnerability maps are prepared to highlight areas with low, medium, high, and very high vulnerability. The vulnerability parameters map showed that shoreline change, land subsidence, and land use are influencing the vulnerability more than other parameters. The CVIw appears to be more favourable to assess the Subang Coast vulnerability, in which the very high vulnerability (43%) is dominant compared to the CVI (21%). This will require urgent protective action from the coast managers. Both CVI and CVIw have a 21% of very high risk in the same areas (Mayangan, Legon Wetan, and Pangarengan Villages), and these areas need protection from the coastal land loss. Meanwhile, the authority has plans for aquaculture in the area, and we suggest that it should be planned thoroughly to ensure that the practice does not destruct the coasts any further.

UV spectroscopy for discrimination of two arabica coffee cultivars in West Java Indonesia: a feasibility study

Arabica coffee variety is one of the key parameters that highly influence the cup quality of arabica coffee. The objective of this current research is to evaluate the possible application of UV spectroscopy for the discrimination of arabica coffee with different cultivars. Green beans from two arabica coffee cultivars (Coffea arabica) of Typica and Sigarar Utang were collected from the same origin in Papandayan mountain West Java, Indonesia. The samples were subjected to the same postharvest treatments (wet cherry processing method). All samples were roasted in medium roasting with 200°C for 16 minutes using a portable roasting machine. A total of 40 samples of Typica and Sigarar Utang were provided by weighing 1 gram of coffee powder (mesh 40) for each sample. The extraction of coffee samples was performed based on previously reported work. The UV-visible spectral data of aqueous coffee samples were acquired by using a benchtop of UV-vis spectrometer in the range of 190-1100 nm. The first two PCs (principal components) with 94% of CEV (cumulative explained variance) could be used to separate between the Typica and Sigarar Utang samples. The Typica samples were situated on the left of PC1 (PC1<0) and Sigarar Utang samples were on the right of PC1 (PC1>0). In the future, it is promising to apply UV spectroscopy for simple and reliable discrimination of arabica coffee cultivar.

The dynamics of meaning in mosque architecture: A case study of old and modern mosques in West Java Indonesia

Humans are homo religiosus with a natural desire that there is an absolute power beyond reasoning which makes them "existent". This is observed from their religious behaviors as well as the continuous increase in their spirituality. Humans have a basic need to worship according to their religious orders and the construction of mosques is considered the fulfillment of the main needs of Muslims to conduct their prayers. The diversity of mosque forms in West Java showed that there is a mutually influencing relationship between the basic need for space to accommodate prayer rituals which tend to be dogmatic and the human desire to appreciate architectural elements of mosques as a form of contextual and dynamic spirituality enhancement. The comparison between the needs and desires in mosque architecture as indicated in previous studies was used as the main reference to understand the dynamics of the meaning in mosque architecture in order to produce new meaning reading diagrams. This was achieved through three main stages with the first being the re-description of the ideograms and typograms pairing in each mosque from the previous studies, the second is the identification of keywords that form the basis of thought for architects, users, and organizers as a series of triangulation processes to reveal new meanings and functions in the case study of mosques, and the third is the placement of the results of the analysis on the Function-Form-Meaning diagram to produce a new meaning reading diagram to identify the dynamics of meaning in mosque architecture in West Java. The contribution of this study is to enrich the theory and method of the meaning process in mosque architecture as well as to serve as a guide for architectural practitioners in designing mosques.

Buruan Sae, a Green Action towards a Communicative City in Bandung City, West Java Indonesia

Abstract Bandung as a metropolitan city barely has a resiliency system of food and nutrient provision. Almost 96% of food imported from the outside of the city, makes the city vulnerable. COVID-19 outbreak intensify these challenges as agriculture, which one of the main strategic sectors in Indonesia, affected as well. One of the solutions that the Bandung City government offered is an innovation called Buruan Sae (Sehat Alami dan Ekonomis). This research provides an insight for innovation from urban planning perspective in the context of Buruan Sae. It is found that Buruan Sae already has all four components and the key component of innovation. Althogh, there is opportunity to develop the innovation further by expanding the urban markets through utilization of ICT and engaging more stakeholders with communicative city concept to broaden the urban networks.

Satellite Remote Sensing Using Earth Observing System in Environmental Monitoring for Hydropower & Floating Photovoltaic Reservoir (Case Study: Algae Blooming on Cirata Reservoir, West Java-Indonesia)

This paper describes the application remote sensing satellite for vegetation in the management of the Cirata Reservoir. This reservoir is a provider of raw water for the Cirata hydropower plant, which is the largest hydropower plant in Indonesia. In the next 2 years, the largest floating solar power plant in Indonesia and Southeast Asia will also be built here. The results of monitoring using Earth Observing System, the area of water hyacinth in the Cirata Reservoir is in the range of 100 to 400 hectares. Cleaning of water hyacinth per month is in the range of 25 to 75 hectares per month. This has not been able to compensate for the water hyacinth area cover that can develop, especially during the rainy season which has an impact on increasing the Water Level. Therefore, this paper also presents several management strategies that have been carried out. In Indonesia in particular, there are many reservoirs that have the potential for algae blooming disturbances and the potential for floating solar power plants in the future. The experiment conducted in Cirata can be an alternative in best practice management.

Risk Assessment and Fractionation of Cadmium Contamination in Sediment of Saguling Lake in West Java Indonesia

This research focused on the speciation and distribution patterns of cadmium in surface sediment from Saguling Lake, which is located in the Upper Citarum River. Organic compounds and heavy metals from anthropogenic activities in the watershed have contaminated the river. Sample from the upper layer of the sediment from Saguling Lake were taken from 12 locations, representing the dry and the rainy seasons in the period 2015-2018. Sediment cadmium (Cd) classification was conducted through a sequential extraction technique to determine Cd’s bioavailability and its risk to the water environment. During the rainy season, the total Cd concentration in the upper layer of the sediment was higher than during the dry season. The average dry and rainy season concentrations were 11.12 ± 2.16 mg/kg and 14.82 ± 1.48 mg/kgm in the sampling locations, distributed differently with the following order of the largest to the smallest concentration: 10B &gt; 1A &gt; 4 &gt; 3 &gt; 2 &gt; 1B &gt; 10A &gt; 7 &gt; 9 &gt; 5 &gt; 6 &gt; 8 for the dry season, and 4 &gt; 1A &gt; 1B &gt; 2 &gt; 7 &gt; 5 &gt; 9 &gt; 3 &gt; 6 &gt; 10A &gt; 8 &gt; 10B for the rainy season. All sampling locations (&gt;60%) showed Cd in the resistant fraction, indicating no significant anthropogenic input of Cd into the surface sediment but more geological input due to high erosion. The values of RAC, ICF, and GFC indicate that the Cd in the surface sediment can be categorized as low risk.
