Abstract

Sonar is a technology that uses the propagation of sound waves to detect the position of an object. Usually, fishermen use sonar to detect fish locations. The problem is that the price of sonar is still expensive, so not all fishermen can afford to use it. One of the devices that can be developed is the HC-SR04 module. HC-SR04 has simple components, and the price is cheap. The use of HC SR04 is still very minimal, so it is necessary to analyze the accuracy of its distance readings on various objects and conditions. The research was conducted using experimental methods in August-September 2023 at the Fishing Exploitation Laboratory, Faculty of Fisheries and Marine Sciences, Brawijaya University. The distance data generated by HC-SR04 is used to measure ceramic, Styrofoam, and fish. Based on the research results, it is known that ceramic and styrofoam objects have a calculated t value = 0 while the one-tail Critical t = 1.65, which means the average distance produced by the tool is the same as the average distance by manual measurement. Meanwhile, in the t-test, the fish samples obtained a value of t stat = 23.24 and t Critical one-tail = 1.65. This shows that the tool will show distance measurement results that differ from manual measurements. Furthermore, the RMSE value of distance measurements on ceramic and Styrofoam objects obtained an average value of 0, which means the measurements are very accurate. Meanwhile, the average RMSE value for fish objects = 37.67, which means that the tool measurements are inaccurate.

Abstract

The Community-Based Water Supply and Sanitation Program (PAMSIMAS) is one of the government's concrete actions to meet water needs in the community. However, implementing the PAMSIMAS program in Kebonagung Village needs more community involvement.  Therefore, this study is conducted to identify the level of community participation using frequency distribution calculations based on Arnstein's participation ladder. Data collection was conducted through a primary survey with 41 respondents using a simple random sampling method, using random respondents who would be used as research samples. The results showed that the level of participation in the PAMSIMAS program in Kebonagung Village was on the fourth ladder of participation, namely consultation with classification into tokenism, which means that the community participates in obtaining information and has the opportunity to argue for decision improvement but is often not accommodated or ignored. It is necessary to increase community participation by paying more attention to community needs so that the sustainability of the PAMSIMAS program continues.

Abstract

The success of waste management cannot be separated from the community's participation. The community's involvement in waste management is still not significantly apparent. Community participation in rural waste management program was investigated in this study since the waste reduction activities still involve waste open burning and burying in the yard which is harmful for the environment. A research model was designed, and a questionnaire was distributed among 112 households (HHs) to analyze their participation in rural waste management programs. A semi-structured questionnaire survey, focus group discussions, and key informant interviews were adopted to acquire qualitative information. The analytical framework includes mass balance analysis (MBA) and Arnstein’s participation (APL) ladder. MBA was applied to measure the current waste reduction rate of each HH, while APL was used to evaluate community participation level in this program. The findings reveal that the average waste reduction is 0.48 kg/HH/day, contributing to a total waste reduction of 17.94 kg/day in the village (24.39% of total waste generation). Measurement using APL unfolds that the extant community participation in Mojosari Village, Bojonegoro Regency, corresponds to a non-participation continuum where villagers are misled by pseudo and tokenistic participation leading to unequal benefit-sharing. Based on these findings, the researchers challenge that communities’ engagement in rural waste management mainly relies on community cadres concerning environmental subjects as well as communities’ economic background. It is concluded where economically weak communities and manipulative figures exist, ensuring a higher community participation level is more challenging

Abstract

This research uses logic model analysis to evaluate the effectiveness of the HIPPA Program (Productive and Safe Rural Irrigation Revitalization Program) in Ngulanan Village. The main objectives of the research are to assess the program's compliance with the technical guidelines of P3TGAI in 2021 and to understand the impact of community participation on program effectiveness. The analytical method involves the formation of a logical framework that encompasses program stages and issues related to sanitation infrastructure, as well as evaluating program compliance based on established criteria. The research results indicate that approximately 53% of the program's success criteria have been met, but there is still room for improvement, especially regarding community participation and effective communication. The analysis also reveals disparities among stakeholders, which can affect community participation. Implementation factors such as a lack of effective communication and resource constraints are also obstacles to program implementation. Therefore, efforts are needed to enhance community participation, improve communication, and allocate resources more efficiently to enhance the effectiveness of the HIPPA Program in the future. The research concludes that evaluation adopting the technical guidelines of P3TGAI 2021 is an essential instrument in assessing and improving program quality, along with a commitment to providing a positive and sustainable impact for the Ngulanan Village community.

Abstract

Cengkir village stands out as a promising area for agricultural land conservation within Bojonegoro Municipality. Consequently, planning and developing water irrigation infrastructure in Cengkir village has become crucial to supporting agricultural activities. However, practical implementation of water irrigation often encounters numerous obstacles, mainly due to mismanagement and insufficient community participation. Therefore, understanding the farmers' perspectives on management and identifying key factors influencing it are essential for further improvement. Cengkir village offers a compelling case for exploration in this regard. This research aims to investigate farmers' views regarding agricultural irrigation management within the Association of Water User Farmers (Himpunan Petani Pemakai Air - HIPPA) in Cengkir Village.Additionally, this study evaluates the relationship among factors influencing farmers' views on agricultural irrigation management. So, to understand the important factors from this perspective, this study employs the Likert Scale's weighting technique. The weighting technique is followed by a non-parametric Spearman Rank Correlation test to define the relationships among the variables and the influencing factors. The findings reveal that farmers' perceptions regarding irrigation management are at a standard level. Moreover, a high correlation exists among factors such as formal education level, motivation, needs, experience in rice cultivation, information knowledge, social environment, support from related departments, and land area, with the perspectives of HIPPA community members towards agricultural irrigation.

Abstract

Sedimentation presents a significant challenge in port management. It poses a risk to arriving and departing ships, potentially causing them to sink. The shallowing of the previous port required the construction of the new Panarukan port pier. This project focuses on using sediment transport modeling to analyze sediment transport patterns, and measure the extent of sedimentation or erosion at Panarukan Harbor. The sediment transport modeling utilizes the MIKE 21 program, which includes various modules such as the hydrodynamic module, the spectral wave module, the sand transport module, and the mud transport module. The data used in this modeling includes depth information, coastline data, wave height and period measurements, river water discharge data, total suspended solids (TSS) measurements, and the average sediment grain size. The modeling was carried out over a five-month period during the rainy season, starting in October 2019 and ending in February 2020. Based on the modeling results, sedimentation occurred at the Sampean River Estuary, causing a significant increase in the bed level of 0.4 meters during the rainy season. The sediment transport pattern of the Sampean River Estuary is characterized by a flow rate of -4200 to 3600 m2/s towards the coast and a flow rate of -2800 to 2800 m2/s perpendicular to the coast. The movement of sediment in the water differs between high and low tides. The concentrations of Total Suspended Solids (TSS) vary from 0.01 to 0.13 kg/m3 or 10 to 130 mg/l.
