Abstract

This research is motivated by the lack of optimal use of bamboo, where bamboo is a natural material that is relatively cheap, easy to obtain and is one of the plants whose use in society is less optimized. In its role as a plant, bamboo can also be used as a material for making liquid smoke for various food needs which can be used for preservation. Shrimp is also a food that people really like, but shrimp cannot last long so natural additives are needed so that shrimp can last longer. Therefore, this research aims to determine the effect of providing liquid smoke from bamboo on shrimp quality, including changes in the smell and texture of shrimp. Observations were carried out at the Non-Wood Forest Products Laboratory, Forest Products Processing Study Program, Samarinda State Agricultural Polytechnic. The research method was carried out by observing shrimp without preservation (control), preserving shrimp with different concentrations, namely 5%, 7% and 9%. Observations of changes in the smell and texture of preserved shrimp were carried out for 6 days. The research results showed that preserving shrimp using liquid smoke from grade 1 bamboo material at a concentration of 7% was more effective than the control, liquid smoke concentrations of 5% and 9%.

Abstract

Project-based learning (PBL) has been increasingly adopted in vocational higher education as a pedagogical approach that integrates technical skill development with interpersonal competency formation. However, the role of cultural and religious character values in shaping student cooperation within PBL environments remains underexplored, particularly in the Indonesian vocational context. This research examines how Islamic character values, namely amanah (trustworthiness), ta'awun (mutual assistance), and musyawarah (deliberation), were expressed and reinforced within the PBL structure implemented in the Wood Engineering study at Politeknik Pertanian Negeri Samarinda, and how this contributed to the development of student cooperation skills. A qualitative descriptive case study was employed, involving 44 fourth-semester students in eleven working groups across multiple wood engineering courses. Data were collected through structured in-depth interviews, participatory observation across 32 sessions, eleven focus group discussions, and document analysis. Thematic analysis following Braun and Clarke six-phase framework was applied, with inter-rater reliability of Cohen Kappa 0.86. Findings suggest that the project structure created favorable conditions for the expression and reinforcement of these character values, though the degree of internalization varied considerably across groups and individual students. The study contributes an empirically grounded illustration of how Islamic character values and cooperative behavior interact within authentic vocational project work, while acknowledging the context-specific nature of the findings
