Study of sediment transport distribution pattern after normalization in the Majalaya Area, Citarum River

Majalaya area in West Java, Indonesia, is prone to extreme rainfall events that cause flooding of the Citarum River. The river flows through the area, naturally containing sediments from erosion upstream that disturb the river balance. Some flat areas of the river retain sediments and cause excessive accumulation, resulting in changing the storage capacity of the river. The accumulation disrupts the flow of water and causes flooding in the area. To mitigate this problem, the River Basin Authority has implemented sediment dredging and river normalization with a total length of 5.4 km in 2020, successfully preventing flooding in the first year. However, subsequent floods that affected more than 7,000 people return to occur due to changes in land use, human activities, and unmanaged erosion upstream. This study examines the sediment accumulation pre-2020, immediately after the normalization efforts 2020, and the current sediment profile 2022. The result provides an overview of the river's morphology, sediment distribution patterns, and potential future profiles. The research results can be used to evaluate flood management risk in the area, including the compound flood risk caused by continuous sedimentation and climate change, e.g., heavier and longer rainfall.

Quality of Water Sources, Sanitation, and Hygiene in Households with Stunted Children in Rural and Urban Areas in West Java

Background: The quality of water sources, sanitation, and hygiene have long been associated with the incidence of stunting in a household. Various studies show that this is also influenced by differences in access to water, sanitation, and hygiene in rural and urban areas. Objectives: This study aims to determine the condition of the quality of water sources, sanitation, and hygiene in household with stunted children under five in rural and urban areas. Methods: The study was conducted in June 2022 using cross-sectional method to 96 household with stunted children under five that were selected by systematic random sampling in Cianjur District and Sukabumi City. Structured questionnaire was used to collect data. Descriptive analysis and bivariate analysis were conducted to determine the distribution of use of water sources, sanitation facilities, and hygiene practices in household with stunted children under five based on the categories of improved sanitation facilities and drinking-water sources by World Health Organization and its differences in rural and urban areas. Results: The sources of drinking and cooking water used by the household with stunted children under five have been entirely improved sources. Most of the households in both areas had defecation facilities used only by household members. There were significant differences in the type of fecal waste disposal in household with stunted children under five in rural and urban areas. Majority of households in rural area (70.0%) already used septic tank for fecal waste disposal while majority of households in urban area (65.2%) disposed their fecal waste to river/lake/sea. Mothers’ handwashing practice at critical time were all above 80%, but only 33.6% of the households had separate handwashing facility and only 50.0% of them provide soap for handwashing. Conclusions: Based on the results, it is known that household with stunted children in rural and urban areas have used proper drinking water sources and have good hygiene practices. However, fecal disposal facilities in urban areas with high prevalence of stunting need to be improved as an effort to reduce stunting prevalence.

Modelling computer assisted audit techniques (CAATs) in enhancing the Indonesian public sector.

Background: This study aims to examine public sector auditors' tendency to use somputer assisted audit techniques (CAATs) in managing their audit works. Methods: A total of 400 questionnaires were distributed to auditors working in the public sectors in Central Java, West Java, and East Java. From the total, 225 questionnaires were returned and completed. The Structural Equation Modelling (SEM) and Partial Least Square (PLS) were used to analyze the data. Results: The empirical findings reveal that performance expectation and facilitating conditions have encouraged auditors to use CAATs in their works. Further, there is a positive influence between the intention to use and CAATs audit. This implies that auditors with an intention will be more open to using the CAATs optimally in achieving effective and efficient work. The utilization of CAATs in public services needs to have strong support from the government and positive attitudes from the auditors as the users of the system. Conclusion: This study covers broad areas of Central Java, West Java, and East Java. Further, the findings add to the literature on emerging markets specifically for Indonesian government auditors' intention and appropriateness of using CAATs. The use of CAATs help to provide auditors information on the highest number of auditees involved in corruption.

Geotourism Versus Wellness Tourism or Should We Better Combine Them in Getwell Tourism? A Case Study in Papandayan Compared to Wellness Tourism in Kuningan, West Java, Indonesia

In the geotourism program and destination, as the scope of the meaning of geotourism from the experts, it is possible to have other recreational activities that take advantage of the program and the destination area. Both require the importance of conservation and respect for nature and local values in the destination area. Even in geotourism activities carried out in geopark areas, the other recreation can be in the form of activities that support the 10 main program areas in geoparks, as well as the activities in the context of achieving the “Sustainable Development Goals” (SDGs). One other recreation that meets these criteria is health tourism. Thus, instead of being contradicted, between geotourism and health tourism it is very possible to be combined and carried out in one agenda simultaneously with complementary each other. This paper examines an experience of combining the application of one part of health tourism with geotourism travel, hereinafter referred to as getwell tourism program. The location of the application of the getwell tourism is the Papandayan area, an important and well-known geotourism destination in West Java. Aspects of site selection are underlined, as well as the determination of the appropriate health tourism program for the location. In the Papandayan geotourism program, health tours are carried out in the form of earthing, forest therapy, pranayama, and soaking in hot springs. The results were evaluated with the wellness program that had been carried out in Kuningan, West Java and the responses from the participants. It was found that the two types of tourism complement each other and some suggestions for improvement. Thus, getwell tourism is not only possible, it can be applied in almost all geotourism and geopark destinations. Health tourism enriches geotourism and vice versa, and both implementations can be combined in the getwell tourism program.

The surface water quality is getting more attention at this time, given the lower quality in some areas of West Java. Mostly the causes of the decline in water quality is due to the disposal of domestic wastewater. Oil and grease is one of the parameter in domestic wastewater that must be considered. Eco enzyme is made from the anaerobic fermentation of organic waste from fruits and vegetables which has a a versatile performance. The aims of this study is to determine whether eco enzyme made from citrus waste has the potential to be used to degrade the concentration of oil and fat in domestic wastewater. The sample used was artificially made from domestic wastewater samples which were intentionally added to oil and grease so that the initial concentration was 19.82 mg/L. In the sample that had been added 5% eco enzyme, the concentration of oil and grease managed to decrease to 13.84 mg/L after 9 days of observation, compared to that which did not add eco enzyme to 15.93 mg/L. The t Test statistical analysis showed that the oil and grease concentration reduction in the two treatments was significant, but the ANOVA analysis results showed that the two treatments did not differ significantly.

Grain yield stability of black soybean lines across three agroecosystems in West Java, Indonesia

Abstract Black soybean (Glycine soja (L.) Merril) is one of the potential agricultural commodities in Indonesia. The multilocation trial is the primary requirement for variety release before farmers can widely use the new varieties. Various stability measurements on grain yields will provide more accurate information in selecting superior lines. The aims of the study were to: (i) identify the effect of genotype by environment interactions (G×E) on black soybean grain yields; (ii) select the black soybean lines with stable and high grain yields in different agroecosystems; and (iii) determine the best representative environment for testing black soybean lines. The field trials used an augmented design that was applied in three blocks for each location. The research was conducted in West Java, Indonesia, specifically in Sumedang, Indramayu, and Majalengka. The three locations are traditionally soybean production areas in West Java. The results showed that G×E significantly affected grain yields, with a contribution of 38.35%. Based on the results of stability testing using parametric, non-parametric, and genotype plus genotype by environments (GGE) biplot measurements, the G13, G22, G25, and G26 lines were considered the most stable and produced the highest yields in the three agroecosystems. In addition, Sumedang is the most representative location for testing black soybeans in Indonesia. Therefore, the four lines can be proposed as new superior lines for black soybeans with high yields and stability in three environments. Information about the relationship between the yield stability parameters can be used for the most accessible parameter selection.

Designing a Corncob Coffee Table By Utilizing the Physical Characteristics of Corncobs

This research is about coffee table product design with corncob material that compromises the value of novelty offered with production factors in order to obtain real cost as a basis for considering the selling price. The coffee table production process is designed using the laminate technique. The processing technique chosen is the bending technique. This research was conducted at Craftindo Kreasi Bandung, precisely located in JI. Ciliwung canal no. 10, and is a continuation of research activities in the 2021 kedaireka matching fund platform program. In the previous study, a coffee table was produced with corncob material but did not use the bending technique. This design is based on opportunities based on previous research, namely (1) the industry has produced various kinds of commodities, but no one has ever tried to make coffee table products. (2) Sources of corn cob material can be obtained in various areas of West Java and can be available every 4 months. (3) In previous research, a coffee table with corncob material has been produced which needs to be developed by taking advantage of the opportunities for corncob characteristics that have been studied in material studies in previous studies, namely the comparative technique. The method used in this design is design iteration. At the end of the research, the output is in the form of a coffee table product prototype with a bending technique. The novelty of this research is the use of corn cobs as the main material and the use of bending techniques during production

Determining Marketing Strategies Based on Farmers Behavior to Increase Farmers Willingness to Buy Nitya’s Feed

The main feed for cattle is forage, while concentrate is only an additional feed. However, currently forage is very difficult to obtain by cattle farmers. In addition, the condition of the quality of concentrate that is not fixed with high prices is also experienced by cattle farmers. Whereas the health of the cattle depends on the feed it consumes. Therefore, Nitya brings innovative cattle feed by producing an all-in-one feed containing concentrate and forage in the form of seaweed as an alternative in one package. Unfortunately, Nitya is still having trouble determining the right marketing strategy. Therefore, this study conducts consumer understanding by identifying what factors most influence the behavior of cattle farmers in choosing cattle feed and providing recommendations for marketing strategies based on these factors. This research was conducted using a qualitative method through semi-structured interviews with 7 farmers who have at least 20 beef cattle domiciled in a suburban area in West Java and analyzed using manual and selective coding methods. The results showed that the social environment of farmers greatly influenced cattle farmers in choosing cattle feed. Cattle farmers often exchange information with each other. In this activity, cattle farmers share any information related to cattle. Cattle farmers are very interested in cattle feed products that can fulfill cattle nutrition and are proven to be able to fatten cattle. In addition, cattle farmers like to buy feed directly where they can reach, this is related to feed quality and feed prices. These findings can be helpful for developing a marketing strategy for Nitya.

The Optimization of Sulphide Oxidizing Bacteria (SOB) for Oil Corrosivity Reduction at Indramayu Coast, The Northern Coastal Area of West Java

Highlight Research First NR-SOB from Indramayu coast was successfully isolated and identified. Bactrerial characterization morphologically and biochemically, foster with in situ hybridization confirm the isolate was Thiobacillus denitrificans, and Arcobacter sp. Both isolate, Thiobacillus denitrificans and Arcobacter sp., were able to grow in sulphide rich environment in the presence of essential nutrient Thiobacillus denitrificans and Arcobacter sp. exhibit an outstanding sulphide oxidation ability up to 100% in the presence of nitrate. Abstract Crude oil production triggers the formation of hydrogen sulphide, also known as souring, which is extremely toxic and corrosive to the environment. It additionally give an adverse consequence to aquatic, terrestrial, and human existence. Studies of hydrogen sulphide reduction in sediments polluted by crude oil have been carried out recently to investigate the capability of indigenous Nitrate-Reducing Sulphide Oxidising Bacteria, hereinafter referred to as NR-SOB, as bioremediation agents. The experiments utilised hydrogen sulphide with 200 µM concentration combined with NO3 with different concentrations of 100 µM, 200 µM, and 300 µM. Measurements of the hydrogen sulfide concentrations were observed up to 48 hours within the experimental period. The SOB used in this study were taken from Balongan Bay at Indramayu coast using Nansen bottle to carry out water sample. The sulphide-oxidising ability of SOB was then evaluated at room temperature in control environment. Methylene blue method was applied to monitor the sulphide concentration. The results showed a complete removal of hydrogen sulphide concentrations in 48 hours accompanied with gradual drops of nitrate in all experiment series. Sulphide oxidation rate was detected to appear between 6.8 and 10.2 fmol/cell/hour. Measurements of cell abundance after 48 hours showed 6.2 x 105, 7.5 X 105, and 8.2 X 105 cell/ml from Experiments I, II, and III respectively. Using MSS selective medium, the bacteria were identified as Thiobacillus denitrificans and Arcobacter sp. Overall, the isolated NR-SOB from the coast of Balongan Bay, Indramayu proves to be a promising candidate for sulphide controls and mitigation.
