Abstract

UKM Citara is developing a seaweed processing business and cultivating catfish in bioflock ponds together with community members as a food security effort due to the impact of the Covid 19 pandemic at the beginning of 2020. Several government/private agencies have visited UKM to learn about seaweed processing and bioflock catfish cultivation, including vocational school students/internship students.  The problem is that the cultivation area of ​​± 2,000 m has not been utilized optimally and SMEs do not yet have an educational tourism concept for their visitors. The aim of the activity is to optimize land use and design a pilot concept for bioflock fish cultivation tourism. The hope is that the cultivated land will be utilized optimally and there will be educational facilities for other parties who come to UKM. The activity method is creating a tourism edu pilot concept in the form of learning tutorials and exploring places at UKM Citara, creating visual images of tourism edu pilots, installing smart ponds, gazebos, gates and irrigation channels in the UKM Citara bioflock fish farming area. The result of this community service activity is the realization of the concept and realization of a tourism edu pilot for seaweed processing and bioflock fish cultivation at UKM Citara which can improve the functionality of ± 2,000 m of empty land which was originally only used for bioflock fish cultivation, then developed into a tourism edu pilot area. which is useful. Visitors can receive education in the form of tutorials on processing seaweed products and cultivating bioflock fish and can explore seaweed processing and bioflock fish cultivation sites. This activity has increased the use of empty land and realized a pioneering educational tourism concept that needs further development.

Abstract

Guluk-guluk District is located on Madura Island, Sumenep Regency, East Java Province, and is known as the location of the long-established Annuqayah Islamic Boarding School. This district has a total rice field area of ​​approximately 1,141 hectares, and the majority of its population is engaged in farming. During the dry season, farmers in Guluk-guluk grow tobacco, which is an important trade commodity with high economic value for the local community. However, tobacco farmer groups in Guluk-guluk District face several serious challenges during the dry season. Lack of rainfall causes the soil in tobacco fields to become very hard, making it difficult for farmers to plant tobacco seeds efficiently. Currently, farmers are forced to use traditional tools such as crowbars to dig holes in the hard soil. This process is time-consuming and requires significant labor, reducing production efficiency and increasing farmers' workload. This situation makes it increasingly difficult for farmers to increase their agricultural yields. Therefore, through the Community Service program, the community service team aims to introduce simple technology in the form of soil drilling tools. This tool is designed to simplify the process of planting tobacco seeds in hard, dry soil and increase farmer efficiency. By using this efficient soil drill, it is hoped that the productivity of tobacco farmers in Guluk-guluk will increase. This tool not only speeds up the planting process but also reduces labor requirements, allowing farmers to focus more on other aspects of their farming. This program is expected to have a positive impact on improving farmer welfare and optimizing agricultural yields in Guluk-guluk District. Furthermore, the implementation of this technology is also expected to provide training and skills development for farmers in Guluk-guluk.

Abstract

Nickel oxide (NiO) is a material used due to its remarkable chemical stability, magnetic properties, and electrical characteristics molecules. One notable feature of NiO is its unreactive surface with water (H2O), making it an ideal candidate for use as a cathode in the electrolysis process to produce hydrogen (H2) gas. During electrolyte process, H2 is produced through the oxidation reaction at the anode and the reduction reaction at the cathode. Despite its potential, the detailed mechanism of H2O molecule decomposition using a NiO electrode remains inadequately explained. This research aims to elucidate the increased energy arising from the attractive forces between NiO and H2O molecules. To investigate these attractive forces, simulations were conducted to understand the chemical characteristics of the molecules, including bond lengths, bond angles, and their properties. The results indicated that the use of NiO electrode could increase the potential and kinetic energy of H2O molecules. This energy increase is attributed to the formation of specific polar and non-polar bonds. Specifically, polar bonds were formed between (1) the nickel (Ni) atom in NiO molecules and the oxygen (O) atom in the H2O molecules and (2) the O atom in NiO molecules and the H atom in the H2O molecules. Non-polar bonds were formed between (1) the H atom in the H2O molecules and the Ni atom in NiO molecules, and (2) the O atom in NiO molecules and the O atom in H2O molecules. This study highlights how these interactions help in the electrolysis process by enabling the efficient breakdown of water molecules and the production of hydrogen gas

Abstract

Natural fiber–based composites are increasingly investigated as environmentally friendly alternative materials. Bamboo fiber is known for its favorable stress distribution due to its natural structure, while cotton fiber contributes to improved stiffness and fiber–matrix bonding. This study aims to evaluate the effect of volume fraction and the combination ratio of bamboo–cotton fibers on the compressive strength of composites. The fiber volume fractions used were 30%, 40%, 50%, and 60%, with combination ratios of 1:1, 1:2, and 2:1. Fabrication was carried out using the vacuum bag method to enhance homogeneity and minimize voids. Compressive testing was conducted according to ASTM D695 standards. The results indicate that increasing fiber volume fraction contributes to higher compressive strength, with a maximum value of 12.8578 MPa at a resin volume fraction of 50% and a bamboo-to-cotton ratio of 1:2. Bamboo fibers provided a dominant contribution to compressive strength, while cotton fibers enhanced stiffness and improved matrix bonding quality.

Abstract

The Kelompok Wanita Tani (KWT) Mandiri in Mojorejo Hamlet, Batu City, manages Nile tilapia biofloc culture and vegetable production in a greenhouse, but water delivery had relied on a manually moved hose. This community service program aimed to install an integrated water supply system linking a storage tank, booster pump, main pipeline, biofloc pond outlet, and greenhouse distribution line. The activity used technical assistance and technology transfer through field observation, hydraulic design, component selection, pipe fabrication, installation, functional testing, and operational guidance. The installed system successfully conveyed water from the storage tank through the pump and pipeline to the biofloc pond outlet, while the greenhouse distribution line was arranged along the planting beds. Visual testing showed a continuous water flow and confirmed the functional connection among the main components. The system simplified pond filling, organized the distribution network, and reduced the need to move hoses repeatedly. However, performance evaluation remained qualitative because pressure, discharge, head loss, and irrigation uniformity were not measured using gauges or flow meters. Therefore, follow-up monitoring is required to quantify hydraulic performance and optimize irrigation scheduling. The program demonstrates that a simple, maintainable water-supply network can support more practical management of integrated aquaculture and greenhouse activities at the community level.
