Abstract

This community service program aimed to improve knowledge, perceptions, and behaviors of the Indonesian diaspora at the Sungai Mulia Learning Studio (SBSM) in Kuala Lumpur, Malaysia, regarding the use of traditional spices for health. The program involved counseling, demonstrations, and completion of an evaluation questionnaire using a Likert scale and open-ended questions. Twenty-three participants took part in the activities and evaluations. The results showed high levels of knowledge and positive perceptions, especially in participants’ belief in the health benefits of traditional spices and their understanding of the functions of basic spices such as ginger and turmeric, commonly used as traditional medicines. Although some participants still chose modern medicine as their main option, they demonstrated a positive attitude toward herbal remedies. Behavioral analysis indicated a strong tendency to prepare, consume, and seek information about spices after attending the program. Qualitative findings supported these results; most participants stated that the activities were beneficial, broadened their insight, and encouraged habit changes toward greater use of herbal medicine. All participants also expressed willingness to join follow-up programs. Overall, this program effectively improved spice-based health literacy and has the potential to be scaled up through more intensive practical sessions and provision of guidance materials.

Abstract

Limbah cair industri tempe memiliki beban organik tinggi (COD, BOD, TSS) yang berpotensi menurunkan kualitas lingkungan jika dibuang tanpa pengolahan. Sebagian besar pelaku UMKM tempe di pedesaan belum memiliki akses terhadap teknologi pengolahan yang murah dan sederhana, sehingga diperlukan pendekatan alternatif berbasis partisipasi masyarakat. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan memberdayakan warga Desa Sukorejo, Trenggalek dalam pengelolaan limbah cair menggunakan eco-enzyme hasil fermentasi sampah organik rumah tangga. Berbeda dari pendekatan konvensional, kegiatan ini menerapkan model partisipatif dengan pembuatan dan penerapan eco-enzyme berbasis rumah tangga yang terintegrasi dengan monitoring masyarakat, sebuah pendekatan yang belum umum diterapkan pada pengelolaan limbah tempe skala kecil. Metode meliputi pemetaan pelaku usaha, sosialisasi, pelatihan pembuatan eco-enzyme (rasio 3:1:10; fermentasi ±90 hari), penyusunan SOP aplikasi (1–5% v/v), dan pendampingan uji sederhana (pH, bau, kekeruhan). Program diikuti 18 peserta dan menghasilkan kelompok pengelola serta unit percontohan. Observasi menunjukkan penurunan bau dan kekeruhan dalam 24–48 jam serta peningkatan pengetahuan peserta. Evaluasi respon peserta menunjukkan kategori sangat baik (rata-rata >90%). Kegiatan ini efektif meningkatkan kapasitas masyarakat dan menunjukkan potensi eco-enzyme sebagai solusi awal pengolahan limbah cair tempe yang murah dan berkelanjutan. Community Empowerment Through Eco-Enzymes for the Management and Degradation of Liquid Waste from Tempeh Industries in Sukorejo Village, Trenggalek Abstract Liquid waste from tempeh production contains high organic loads (COD, BOD, TSS) that can degrade environmental quality if discharged without proper treatment. Most small-scale tempeh producers in rural areas lack access to simple and low-cost treatment technologies, necessitating an alternative approach grounded in community participation. This Community Service Program (PKM) aims to empower residents of Sukorejo Village, Trenggalek in managing liquid waste using eco-enzymes produced from the fermentation of household organic waste. Unlike conventional approaches, this program adopts a participatory model involving the household-based production and application of eco-enzymes integrated with community monitoring—an approach that is rarely implemented for small-scale tempeh wastewater management. The methods included stakeholder mapping, awareness-building activities, training on eco-enzyme production (3:1:10 ratio; ± 90-day fermentation), preparation of application SOPs (1–5% v/v), and facilitation of simple testing (pH, odor, turbidity). The program involved 18 participants and resulted in the formation of a management group and a pilot demonstration unit. Observations indicated reductions in odor and turbidity within 24–48 hours, alongside improved participant knowledge. Participant response evaluations showed excellent results (average >90%). This program effectively enhanced community capacity and demonstrated the potential of eco-enzymes as a low-cost and sustainable preliminary solution for treating liquid waste from tempeh production.

Abstract

Optical communication in digitalisation is a significant catalyst in supporting high-speed and large capacity data transmission. However, optical communication applications face substantial challenges, such as energy loss, dispersion effects, and signal stability over long transmission distances. One material that has the potential to overcome these problems is ruby due to its nonlinear characteristics. This research work numerically investigates soliton propagation in ruby material analysis as a Nonlinear Schrödinger Equation numerical modelling and three-dimensional visualisation with Cubic B-Spline, modified Korteweg-de Vries-Zakharov-Kuznetsov, and Boussinesq methods to understand ruby material characteristics more deeply. The simulations show that the soliton waveform remains stable during propagation, with its amplitude confined within approximately -1.05 to 0.35, indicating robust shape preservation under anisotropy and temperature variations. like most previous studies that are limited to one or two dimensional modelling or to dispersive fibre media, this study implement a full 3D NLSE framework tailored to the physical properties of ruby. The results show that both numerical modelling and three-dimensional visualisation indicate that ruby material can maintain the soliton waveform during propagation. This finding suggests that ruby has the potential to be applied in optical communication systems with high stability to support long-distance data transmission.
