Coconut Shells

Bio-musical instruments can be defined as musical instruments made from plant wastes in the surrounding environment. One of the plant waste that is easily found in the community is coconut shell. Coconut shells are often overlooked for their use as a creative medium, especially in the field of music. Musical instruments are the main media for creativity in the art of music. The rise of musical instruments or musical instruments with high prices has become one of the inhibiting factors for young people to be creative in the field of music. Seeing this phenomenon, it is deemed necessary to develop people's creativity in making their own musical instruments at economical prices but still able to compete with manufactured musical instruments. In making this bio-instrument, the method used consists of problem identification, preparation, application, and evaluation. Through this method, the results obtained in the use of coconut shell waste into creative media are the Kalimba instrument played by plucking the iron keys as the source of the tone, while the coconut shell is used as the main medium for the sound resonance of the Kalimba instrument. Kalimba is classified into a type of lamellophone instrument, which is a musical instrument that has a tongue or a thin plate. In addition to the easy-to-use manufacturing process, the tools and materials in making these instruments are also easy to find and can even take advantage of used materials. The results of making bio-musical instruments are expected to become a reference and reference for academics and non-academics, regarding how to make musical bio-instruments using coconut shell waste.

IMPLEMENTATION OF SCIENCE AND TECHNOLOGY FOR THE DEVELOPMENT OF COCONUT SHELL WASTE AS AN EFFORT TO INCREASE COMMUNITY INCOME. The problems that occur in the community of Sei Paham Village are not yet optimal use of coconut, which is one of the largest coconut production villages in Sei Kepayang District. It requires the acquisition of science and technology in maximizing coconut shell waste into charcoal. The purpose of the service is to implement science and technology in processing coconut shell waste into charcoal as an effort to increase the income of the people of Sei Paham Village. The community empowerment method uses participatory learning and action to be very useful in increasing knowledge and skills by involving community participation in several ways, including: (1) analysis of the situation of potential derivative products from coconut waste; (2) able to design the charcoal combustion devices that have been produced with the service team; and (3) skilled in quality charcoal production. The results of dedication are seen in increasing income and skills in utilizing shell waste. The application of science and technology in developing the potential of shell waste also has a positive impact on the surrounding environment, this is there is no longer a coconut shell buildup because the community has been able to optimize the shell using a coconut shell combustion device to become charcoal.

Liquid smoke is a natural food preservative which can be made of coconut shells through the pyrolysis process. This study aimed to design a pyrolysis reactor and utilize the coconut shell waste to produce liquid smoke as a natural preservative of tofu. 1.5 kg of chopped coconut shell was pyrolyzed at 400C for 5 hours and produced 488 mL of grade 3 liquid smoke with a yield of 34.23%. The liquid smoke was then purified by extraction using ethyl acetate (1: 1 ratio) solvent and 70C temperature for 2 hours. The extract was then distilled at 80C and produced grade 1 liquid smoke. This liquid smoke had an acid content of 12.26% and a phenol content of 0.73%. This liquid smoke was then applied to tofu for 3 days and analyzed the microbial contamination. The smallest amount of microbial contamination was found in the samples of yellow tofu and white tofu coated with liquid smoke and stored in the refrigerator for 1.4 × 105 CFU / mL and 8 × 103 CFU/ml.

This paper offers a series of characterizations of prototypical musical timbres, called Timbre Trait Profiles, for 34 musical instruments common in Western orchestras and wind ensembles. These profiles represent the results of a study in which 243 musician participants imagined the sounds of various instruments and used the 20-dimensional model of musical instrument timbre qualia proposed by Reymore and Huron (2020) to rate their auditory image of each instrument. The rating means are visualized through radar plots, which provide timbral-linguistic thumbprints, and are summarized through snapshot profiles, which catalog the six highest- and three lowest-rated descriptors. The Euclidean distances among instruments offer a quantitative operationalization of semantic distances; these distances are illustrated through hierarchical clustering and multidimensional scaling. Exploratory Factor Analysis is used to analyze the latent structure of the rating data. Finally, results are used to assess Reymore and Huron’s 20-dimensional timbre qualia model, suggesting that the model is highly reliable. It is anticipated that the Timbre Trait Profiles can be applied in future perceptual/cognitive research on timbre and orchestration, in music theoretical analysis for both close readings and corpus studies, and in orchestration pedagogy.

"Meghalaya is a richly inhabited Indian state. Drums, flutes of bamboo and hand-held small cymbals are a common ensemble. The advent of Christianity in the middle of the 20th century marked the start of a decline in tribal popular music. Over time, Meghalaya’s music scene has evolved, attracting many talented artists and bands from both traditional and not-so traditional genres. Any of the most recent Meghalaya musicians and bands is: The Plague Throat, Kerios Wahlang, Cryptographik Street Poets, etc., Soulmate, Lou Majaw, and Snow White. Meghalaya’s music is characterised by traditional instruments and folk songs. The Musical Instruments of Meghalaya are made from local materials. Meghalayan people honour powerful natural forces and aim to pacify animistic spirits and local gods. The instruments are made of bamboo, flesh, wood, and animal horn. Any one of these musical instruments is considered to have the ability to offer material benefits. The Meghalaya musical instrument is an essential part of traditional folk music in the region. In this article, we offer an overview of the folk musical instruments of Meghalaya. Keywords: Idiophone, Aerophone, Chordophone, Membranophone, Trumpet. "

This study explored advanced musicians’ dispositions to flow in musical practice. A total of 168 classically trained musicians answered a questionnaire assessing their proneness for flow experience during musical practice and associations between flow and demographic factors, practice routines and musical instruments. Dispositions to flow in musical practice did not vary across musical instrument groups, age or gender. Positive associations were found between daily practice time and flow, suggesting that flow may contribute to engagement with daily practice. Negative associations between music practice experience and loss of self-consciousness and challenge–skill balance were found, suggesting that even among experts the level of task complexity during practice may affect perceptions of competence. While six individual flow indicators were frequently experienced, three indicators were much less experienced, pointing to the existence of another similar relevant experience in the practice of expert performers, named as optimal practice experience. The article finishes with implications regarding the benefits of flow for teaching and learning practices.
