Abstract

Tinta cumi merupakan limbah sampingan dari cumi-cumi yang belum termanfaatkan dengan baik. Pemanfaatan tinta cumi masih terbatas pada produk segar, yang mengakibatkannya tidak bisa disimpan dalam waktu yang lama. Sehingga diperlukan olahan lanjutan untuk memperpanjang masa simpan seperti dijadikan dalam bentuk serbuk. Tujuan penelitian ini adalah untuk mengetahui karakteristik fisikokimia tinta cumi yang telah diawetkan dalam bentuk serbuk. Metode penelitian yang digunakan pada penelitian ini adalah deskriptif eksploratif dengan melakukan pengamatan pada serbuk tinta cumi. Pengamatan dilakukan dengan melakukan analisis proksimat, analisis SEM-EDX dan analisis FT-IR. Kandungan lemak dan protein serbuk tinta cumi memiliki nilai lebih rendah dibandingkan dengan bagian tubuh lainya. Analisis SEM-EDX menunjukan bahwa serbuk tinta cumi memiliki bentuk yang tidak beraturan dengan unsur penyusun utama C, N dan O. Hasil analisis FT-IR menunjukan bahwa gugus fungsi yang terdapat di dalam serbuk tinta cumi adalah gugus fungsi fenolik (O-H) dan amina (N-H) yang berpotensi menjadi senyawa antibakteri dan juga antioksidan.Kata Kunci : ABSTRACTSquid ink is a byproduct of squid that has not been utilized properly. Despite its potential, the use of squid ink is still limited to fresh products, which means it cannot be stored for a long time. Therefore, further processing is needed to extend the shelf life, such as making it into powder form. The objective of this study is to determine the physicochemical characteristics of squid ink that has been preserved in powder form. The research method used is exploratory descriptive by observing the squid ink powder. Proximate analysis, SEM-EDX analysis, and FT-IR analysis were carried out to observe the powder. The fat and protein content of squid ink powder is lower compared to other body parts. SEM-EDX analysis shows that squid ink powder has an irregular shape with the main constituent elements of Carbon, Nitrogen, and Oxygen. The results of FT-IR analysis show that squid ink powder contains functional groups of phenolic (O-H) and amine (N-H), which have the potential to be an antibacterial compound and an antioxidant.

Abstract

The fisheries sector is one sector that has great potential in improving the economy. To increase the income of fish cultivators, farmers need to manage their business results better before they were marketed or sold. The welfare level of fish farmers was still low, this is not because the selling price of fish is low, nor is it because of the large number of imported fish, but rather due to the government's lack of attention to the fishery sector, especially freshwater fisheries. This study used a descriptive method, which was conducted in the Lima Puluh Kota Regency. The selection of the research area was carried out in purposive method. Determination of the research sample using the snowball sampling method. Collecting data using interview method using questionnaires to obtain primary data and documentation method to obtain secondary data. The data analysis method used descriptive qualitative analysis and quantitative analysis using a triangulation technique approach that tested the validity of the data using methods, sources, and theories. The results showed that the factors that significantly influenced the income of fish farmers in Nagari Andaleh, Luak District, Lima Puluh Kota Regency were the number of harvests (X1), land area (X2), production costs (X5), and the selling price of production (X6).  While the factors that do not affect the income of rice farmers are farmer education (X3), farmer age (X4) and other occupations (X7).

Abstract

The limited knowledge owned by KWT Sekar Arum in seedling hydroponic plant seeds and lack of manpower to maintain the seedlings caused the seeds produced to be poor (small stems and few leaf shoots) and some were eaten by pests. Poor seeds produce plants that are not optimal. Therefore, in this community service activity, a nursery chamber is designed for seedling hydroponic plant seeds that utilize solar panel energy as a source of electrical energy in indoor hydroponic plant seed cultivation. This nursery chamber is equipped with artificial light and automatic irrigation so the seedling process can save energy and time. Artificial light is made using 2 types of LED lamps with a red spectrum and a blue spectrum arranged at a certain distance so that the intensity of the light produced is 100 mol/m2/s. To be utilized optimally, all members of KWT Sekar Arum were given counseling and training related to the use of the nursery chamber. In addition, KWT Sekar Arum is also assisted in the process of transplanting and maintaining hydroponic plants so the results are maximized. Based on the results of the evaluation, it can be seen that the transfer of technology provided can be utilized properly by KWT Sekar Arum, the seeds produced from the nursery chamber already have 3-4 leaf shoots when they are 9 days old and ready to transplant, and the results of hydroponic plants produced has been maximized with wide and many leaves.

Abstract

Yutuk, which is also known as undur - undur laut, is a typical souvenir from Widarapayung Wetan beach. The handling of yutuk before consumption by community groups processing yutuk is still in a simple way by soaking it in a bucket or tub. Depuration of yutuk or shellfish makes the dirt contained in the organs of the body come out and can reduce the heavy metal content contained therein. This Community Service activity aims to increase the education of yutuk processing groups to use the depuration method with a special yutuk tub with a recirculation system that uses natural filters such as ginger coral, zeolite and activated charcoal. The Community Service activity stage begins with interviews and field observations and then continues with a Focus Group Discussion (FGD) and then implements a yutuk depuration tub for the yutuk processing group in Widarapayung Wetan village. Through Community Service activity, the yutuk processing community groups are equipped with good and correct depuration techniques so that they can be achieved properly and the community can consume them safely and comfortably.

Abstract

This study aimed to determine the effect of adding bay leaf solution on the pH and organoleptic quality of mackerel during room temperature storage. The experiment used a Completely Randomized Design (CRD) with four concentrations of bay leaf solution (0%, 15%, 20%, and 25%) and two observation times (0 and 24 hours), each with three replications. The bay leaf solution was prepared through washing, grinding, boiling, filtering, and dilution. The observed parameters included pH, eye, gill, mucus, flesh, aroma, and texture based on organoleptic evaluation. The results showed that at 0 hours, treatments with 20% and 25% concentrations produced significantly higher pH values compared to other treatments (p<0.05), while after 24 hours no significant differences were found (p>0.05). Organoleptic tests indicated a decline in quality for all parameters after 24 hours of storage. Significant effects of bay leaf solution were observed only in certain parameters during the initial storage stage, particularly gills and texture, while its effectiveness decreased during longer storage. In conclusion, bay leaf solution has the potential to maintain the quality of mackerel during the early stage of room temperature storage but is less effective in preventing quality deterioration after 24 hours.
