Abstract

Household waste, which is mostly in the form of food waste such as vegetables and fruits, is a source of waste accumulation. More than fifty percent of the waste accumulation in Banyudono village, Boyolali, Central Java is household waste. The accumulation of garbage causes environmental pollution problems that can result in a decrease in the quality of life of residents. Garbage accumulation occurs because residents only throw it into the surrounding environment or rely on garbage transport trucks to be disposed of in landfills. This is due to the lack of knowledge among of residents (the participant of the service activities) in waste processing. Proper waste management not only makes the environment clean and healthy, but also improves the community's economy through the creation of value-selling products. To overcome the partner's problem, namely the accumulation of waste, the service team provides solutions according to the partner's needs, namely the transfer of science and technology (IPTEK) to process household waste (organic) into organic fertilizer (compost). The transfer of science and technology to Banyudono Village residents take place in July 2023 and participants were given assistance to implement the science and technology to treat waste independently. The results were monitored 3 months later according to the known composting method. Composting is done using EM4 bioactivator so that the results can be harvested within 3 months of composting. Compost quality analysis is carried out after the compost is physical and chemical mature which confirmed by checking pH and levels of nitrogen, phosphorus, and potassium. The obtained compost was blackish with a smell like earth, and has a fine texture. The compost had a pH of 6.9 and the nitrogen, phosphorus, and potassium levels meets SNI standards. Through this activity, participants able to processing household waste independently.

Abstract

Elementary school teachers in Gunungpati District, Semarang, still experience difficulties in: (1) implementing learning that can prepare students to face the minimum competency assessment (AKM), (2) compiling instruments that can be used to train students to face AKM, namely literacy and numeracy. Therefore, it is necessary to carry out training activities for teachers in the KKG, in order to prepare them to familiarize their students with knowing and taking literacy and numeracy tests. The aim of this service activity is to provide training for teachers through KKG activities with a facilitation-based Action Learning model. The specific aim is to assist elementary school teachers in improving their pedagogical competence in the areas of learning and evaluation. The problem solving method that has been agreed upon by partners is the implementation of programmed training. The solution method design refers to the facilitation-based Action Learning model. Action learning is defined as a process in which a group of people come together regularly, help each other to learn, and share experiences. This training requires a tutor who acts as a facilitator, and continues with the mentoring phase. Before carrying out the training, a Focus Group Discussion (FGD) was held with several elementary school principals and the head of the Dewi Kunthi KKG, Gunungpati District, Semarang. The results of the FGD are used to design training scenarios for each activity and training materials. The success of the training was marked by the increasing ability of teachers in designing science and science lessons and preparing AKM questions, namely literacy and numeracy.

Abstract

Masalah pengelolaan sampah organik di Indonesia menjadi perhatian serius karena tumpukan sampah organik yang tidak terkelola dengan baik dapat menimbulkan berbagai masalah lingkungan dan kesehatan. Desa Rejosari dengan populasi 3.012 jiwa menghadapi rendahnya kesadaran masyarakat dalam pengelolaan sampah, yang tercermin dari penumpukan sampah di lahan tidak produktif serta keterbatasan pengetahuan dan keterampilan masyarakat dalam mengolah sampah organik menjadi produk bernilai ekonomi. Oleh karena itu, dilakukan kegiatan pemberdayaan masyarakat yang bertujuan meningkatkan kesadaran masyarakat Desa Rejosari tentang pentingnya pengelolaan sampah organik sekaligus memberikan keterampilan dalam pembuatan kompos dan eco-enzyme sebagai solusi pengelolaan sampah organik. Kegiatan ini meliputi edukasi mengenai bahaya sampah organik, pelatihan pembuatan kompos dan eco-enzyme, serta pemanfaatan hasil olahan untuk kegiatan urban farming. Data dikumpulkan melalui observasi, wawancara, dan kuesioner. Hasil kegiatan menunjukkan bahwa edukasi, pelatihan, dan pendampingan berhasil meningkatkan pengetahuan dan keterampilan masyarakat dalam mengolah sampah organik, serta menghasilkan kompos dan eco-enzyme yang dimanfaatkan untuk pertanian lokal. Partisipasi masyarakat juga semakin aktif dengan adanya fasilitasi alat pengolahan sampah. Keberhasilan program ini menunjukkan bahwa edukasi dan pelatihan langsung mampu mendorong pengelolaan sampah yang lebih berkelanjutan sekaligus membuka peluang peningkatan kesejahteraan masyarakat melalui produk hasil pengolahan sampah.
Analysis of the Effect of Fixators and pH Conditions on the Color Absorption of Cotton with Natural Teak Leaf Dyes (Tectona grandis Linn. f.) Priatmoko, Sigit; Rahmawati, Nova Eka; Harjono, Harjono; Sulistyaningsih, Triastuti; Muna, Nala Izzul

Abstract

Growing concern about the environmental impacts of synthetic dyes has renewed interest in plant-based colorants for sustainable textile dyeing. Teak leaves (Tectona grandis Linn. f.) are rich in polyphenolic compounds with strong chromophoric properties, but the influence of fixation conditions and dye-bath pH on fabric performance requires further clarification. This study evaluated the effects of mordant type and dye-bath pH on color intensity and washing fastness of cotton fabrics dyed with teak leaf extract. Cotton samples were dyed at pH 4, 6, 8, 10, and 12, then post-mordanted using alum, ferrous sulfate, or tamarind extract. Color characteristics were quantified using the CIE Lab* system, and washing fastness was assessed following SNI ISO 105-C06:2010. Ferrous sulfate consistently produced the darkest shades and the highest washing fastness ratings (TLW 3–4 to 4), likely due to stable metal ligand complex formation among Fe²⁺ ions, dye molecules, and cellulose fibers. Mildly alkaline dye baths (pH 8–10) enhanced color depth, whereas extreme alkalinity (pH 12) decreased dye uptake, presumably because stronger electrostatic repulsion limited adsorption. Overall, teak leaf extract shows strong potential as an eco-friendly natural dye, and the results emphasize that careful mordant selection and pH optimization are essential to achieve durable coloration for sustainable textile processing.
