Abstract

This research was aims to know 1) whether there was a significant difference from tensile strength of wood connection with plastic bottle waste between A bottle, B, C, D, E, and F bottle, 2) plastic bottle which produced the wood connection with the highest tensile strength. This research used quantitative method of experimental approach. The population of this research were wood with the connection of plastic bottles by heating. This technique was inspired by Micaella Pedros, an England artist who first applied it known as Joining Bottles. Dimensions for tensile test parallel that was 2,5 x 2,5 x 46 cm with total 30 samples. The length of the bottle connection is 10 cm with 1 layer only. This research used quantitative method of experimental approach. Data analysis used one way anova test, 0.05 significance level with the requirement of normal data and homogeneous data. Statistical data of this research results showed 1) no significant difference tensile strength of the six plastic bottles connector. 2) The F bottle produced the highest tensile strength that was 0,622 MPa.

Abstract

The study aims to identify and analyze various types of risks faced by smallholder goat farmers in Dampyak Village, Tegal Regency, and to evaluate the risk management strategies they have implemented. A descriptive-analytical method was used with a survey approach involving five purposively selected goat farmers. Data was collected through interviews and questionnaires, then analyzed based on 23 risk indicators covering production, economic, environmental, and managerial aspects. The findings show that most indicators fall under the high-risk category, with an average aggregate score of 4,5. Major risks include extreme weather changes, livestock diseases such as scabies, limited forage availability, and market price fluctuations. From a managerial perspective, perspective, farmers still face challenges in record-keeping and adopting technology, although their awareness of risk management importance is relatively high. Mitigation strategies include routine vaccination, maintaining pen hygiene, providing alternative feed, and expanding marketing networks.
