Abstract

Fishball MSMEs Ulfa’s face persistent challenges in raw-material selection, good manufacturing practices, and quality control. This community service program strengthens food safety and quality control in a Serang City MSME through: (1) CPPOB -IRTP/GMP mentoring aligned with the Indonesian Standard for fishball, (2) implementation of an infrared (IR/NIR)–based freshness sensor for rapid screening and a TVB-N colorimetric freshness label as an on-package alert, and (3) packaging and cold-chain improvements. Methods included baseline CPPOB assessment, training, SOP implementation, trials of the IR sensor/TVB-N indicator, and pre–post evaluation (knowledge scores, SOP compliance, and simple shelflife testing). Results showed an increase of 21 points in knowledge (58→79), CPPOB compliance rising from 61% to 88%, and chilled shelf life of cooked fishballs extended from 2 to 6 days under controlled conditions (0–4 °C). The program also facilitated P-IRT/SPP-IRT documentation readiness and label improvements. These findings indicate that combining CPPOB mentoring, IR freshness sensing/TVB-N indicators, and standards-based cold-chain practices can improve traceability, quality, and safety performance in MSMEs. Abstrak UMKM bakso ikan Ulfa memiliki tantangan konsisten pada seleksi bahan baku, penerapan praktik produksi yang baik, dan pengendalian mutu. Program pengabdian ini bertujuan memperkuat keamanan pangan dan kendali mutu pada UMKM mitra di Kota Serang melalui: (1) pendampingan CPPOB-IRTP/GMP yang diselaraskan dengan SNI bakso ikan, (2) implementasi sensor kesegaran berbasis inframerah (IR/NIR) untuk skrining cepat bahan baku serta indikator warna TVB-N sebagai on-package alert, dan (3) perbaikan pengemasan serta cold chain agar mutu terjaga. Metode mencakup asesmen awal (checklist CPPOBIRTP), pelatihan, implementasi SOP, uji adopsi sensor IR/indikator TVB-N, serta evaluasi pra–pasca (skor pengetahuan, kepatuhan SOP, dan uji ketahanan simpan sederhana). Hasil menunjukkan peningkatan 21 poin skor pengetahuan (dari 58→79), kenaikan kepatuhan CPPOB dari 61% menjadi 88%, serta perpanjangan masa simpan dingin bakso matang dari 2 menjadi 6 hari pada kondisi terkontrol (0–4 °C). Program juga memfasilitasi kesiapan dokumen P-IRT/SPP-IRT dan penyempurnaan label. Temuan inimengindikasikan bahwa kombinasi pendampingan CPPOB, sensor IR/indikator TVB-N, dan praktik cold chain berbasis standar dapat meningkatkan ketertelusuran mutu serta keamanan produk UMKM.

Abstract

Work accidents can occur in any work activity. Work accidents can be caused by worker negligence or inappropriate tools used in a procedure. The aim of this research is to identify the possibility of work accidents occurring so that they can be prevented. This research uses the HIRARC (Hazard Identification Risk Assessment and Risk Control) process to identify hazards, calculate threats, and manage impacts to prevent industrial accidents. This research was conducted at Tunas Toyota Balaraja which is located on Jl. Raya Serang No. Km 24, Balaraja, Kec. Balaraja, Tangerang Regency, a company that operates in the field of car sales and vehicle servicing. The research process took 40 working days and saw firsthand all the activities at Tunas Toyota Balaraja.  Tunas Toyota Balaraja is a company that sells and repairs four-wheeled cars. Car maintenance is a task that is carried out when the car is damaged. This task is not performed every day and only incidentally if the car breaks down. Car maintenance can be divided into three categories: mechanical maintenance, interior, and repairs. The results obtained in this research indicate that Tunas Toyota Balaraja has gaps in the risk identification process due to a lack of knowledge about work safety and the results of the data obtained show that every work activity in the Tunas Toyota Balaraja workshop has a high level of work risk. Because the activities here are directly related to materials that contain chemicals such as oil, battery water, radiator water, brake fluid. direct contact with gasoline, this risk of course causes economic losses. Therefore, all mechanics strive to use complete PPE on all high-risk work. Vehicle maintenance activities are divided into two activities, namely car repairs if problems occur and periodic maintenance activities based on the distance traveled by the car. In this activity there are 9 high risks, 7 medium risks, and 1 low risk. The high risk comes from potential dangers such as slipping, head injuries, scalded hands due to direct contact with hot oil, electric shock when charging the battery. Control in the form of eliminating all forms of work hazards, technical supervision and training, administrative control in the form of providing funnels when pouring oil to avoid oil spills and PPE by wearing rubber gloves. Moderate risk is caused by eye irritation and hand injuries from sharp objects. Risk control is carried out in the form of elimination, engineering and management techniques in the form of mechanical safety guarantees and pre-work safety meetings.

Abstract

The electrical topic is considered a material that is difficult to understand because electricity is a substance that is not seen but can be felt. The objectives of this study were 1.) to develop digital textbooks for basic electricity materials based on problem-based learning; 2.) to analyze the feasibility of digital textbook products for basic electricity materials based on problem-based learning. This research is development research using the 4D model, namely define, design, develop, disseminate. This study involved language, material, and media experts in validating research products. The research subjects were students of technical engineering vocational education in one of the public universities in Indonesia who took Basic Electrical and Electronics courses, namely 25 students. The data collection technique used interviews, document analysis, and questionnaires. The data analysis technique used descriptive statistical analysis. Based on the research results that have been done, it has resulted in several conclusions, namely; 1.) Development of digital textbooks on basic electricity materials based on problem-based learning is carried out by referring to the 4D model development steps, namely define, design, develop, and disseminate; 2.) The appropriateness of digital textbooks according to the media expert's assessment of getting a mean score of 3.61 is declared very good, the material expert's assessment is 3.52, which is declared very good, and the user response gets an assessment of 3.51, which is declared very good Theoretically developed digital textbooks are able to increase student interest and motivation to learn basic electrical materials in an easy way.
