Abstract

[Bahasa]: Gerabah merupakan salah satu produk unggulan daerah di Desa Banyumulek Kabupaten Lombok Barat, Provinsi Nusa Tenggara Barat. Industri ini telah berlangsung lebih dari setengah abad, dan menjadi mata pencaharian pokok hampir 80% masyarakat di Desa Banyumulek. Kegiatan pengabdian ini bertujuan untuk sosialisasi dan praktek penerapan teknologi material komposit menggunakan bahan alternatif untuk pembuatan gerabah. Bahan alternatif yang digunakan berasal dari limbah abu pembakaran gerabah. Tim pengabdian bermitra dengan KIAT Gerabah Lombok, yang merupakan kelompok pengrajin gerabah beranggotakan 25 orang. Selain itu, kegiatan ini bertujuan untuk mengurangi dampak negatif dari limbah abu dan meningkatkan nilai ekonomisnya. Pengabdian dilakukan dengan metode Participatory Action Research (PAR) dan Focus Group Disscussion (FGD). Penerapan kedua metode dapat meningkatkan pemahaman dan pengetahuan para peserta pengabdian tentang diversifikasi dan teknik pembuatan gerabah dengan teknologi komposit sebanyak 30-80%. Sedangkan indeks kepuasan peserta pengabdian menunjukkan sebanyak 76% peserta pengabdian merasa puas dan sangat puas terhadap pelaksanaan kegiatan. Diversifikasi bahan baku dalam pembuatan gerabah, diharapkan dapat menjaga keberlangsungan industri gerabah di Desa Banyumulek sebagai menjadi salah satu warisan budaya dan produk unggulan daerah yang perlu dilestarikan.

The industry, which has existed for over half a century, serves as the primary livelihood for nearly 80% of Banyumulek's population. This community service activity aimed to introduce and practice composite material technology using alternative materials derived from pottery firing ash waste. The service partnered with KIAT Gerabah Lombok, a pottery artisans' group with 25 members. The objectives included mitigating the negative impacts of firing ash waste and enhancing its economic value. Employing Participatory Action Research (PAR) and Focus Group Discussion (FGD) methods, the activities improved participants' understanding of diversification and composite technology pottery techniques by 30-80%. The participant satisfaction index revealed that 76% were satisfied or very satisfied with the activity. Diversifying raw materials in pottery making is expected to sustain the pottery industry in Banyumulek Village, preserving it as a cultural heritage and regional hallmark.

Abstract

Pencemaran limbah di kawasan pesisir adalah tantangan serius yang memerlukan pemahaman mendalam tentang sumber pencemaran, dampaknya, dan solusi yang berkelanjutan. Kegiatan pengabdian ini bertujuan untuk mengatasi masalah ini melalui penerapan pendekatan berbasis kimia dan matematika sebagai media edukasi yang lebih efektif kepada masyarakat pesisir, khususnya masyarakat Pantai Gading yang menjadi mitra kegiatan pengabdian. Pada tahap persiapan, survey lingkungan dilakukan untuk mengidentifikasi sumber-sumber utama pencemaran limbah di wilayah tersebut dan mengetahui pemahaman awal masyarakat tentang pencemaran limbah. Hasil survey ini menjadi dasar untuk merancang program edukasi yang sesuai. Selanjutnya, program edukasi kimia dan matematika dikembangkan dan disampaikan kepada masyarakat pesisir menggunakan metode Focus Group Discussion (FGD) yang melibatkan 18 orang peserta. Hasil dari kegiatan menunjukkan perubahan signifikan dalam pemahaman masyarakat tentang penerapan edukasi kimia dan matematika dalam mengatasi pencemaran limbah serta peningkatan kesadaran mereka dalam mengambil tindakan yang konkret.

Abstract

Kegiatan pendampingan belajar ini dilaksanakan di SDN 1 Senaru sebagai bentuk kontribusi nyata dalam meningkatkan minat dan motivasi siswa terhadap mata pelajaran Matematika dan Sains. Berdasarkan observasi awal, sebagian besar siswa mengalami kesulitan dalam memahami konsep dasar kedua topik tersebut serta menunjukkan minat belajar yang rendah. Oleh karena itu, kegiatan ini bertujuan untuk memberikan pengalaman belajar yang menyenangkan, interaktif, dan aplikatif melalui metode eksperimen yang sederhana, permainan edukatif, serta pendekatan kontekstual yang sesuai dengan tingkat perkembangan siswa sekolah dasar. Hasil kegiatan menunjukkan adanya peningkatan antusiasme dan partisipasi aktif siswa selama proses pendampingan berlangsung. Evaluasi dilakukan melalui observasi, kuisioner sederhana, dan refleksi kegiatan. Program ini diharapkan dapat menjadi model pembelajaran alternatif yang mampu menumbuhkan semangat belajar Matematika dan Sains sejak dini.

Abstract

Graphs are an excellent instrument that provides an algebraic structure for visualizing and interpreting molecule structures and characteristics. As a result, the problem statement arises regarding how we can interpret graphs with eigenvalues concerning their corresponding matrices. Such questions can be answered by studying spectral graph theory. This research focuses on graphs whose vertex sets are group elements in which the structure of ℤn groups and the definition of a prime coprime graph serve as the foundation for the graph building used in this study. The matrix construction of the graph is based on transmission-based matrices including Weiner-Hosoya and distance signless Laplacian matrices. Research methods include investigating the transmission properties and formulation of the characteristic equation using block matrices. The results obtained are a comprehensive analysis of eigenvalues, spectrum, and spectral radius leading to the prime coprime graph energy for ℤn groups corresponding to both matrices.

Abstract

Hygiene and sanitation are inseparable components of environmental health. Gegutu Reban Hamlet, Dasan Geria Village, is one of the areas in West Lombok facing challenges in sanitation management due to the annual increase in population due to the clearing of agricultural and plantation land for new settlements. The main problem currently being faced is low public awareness and knowledge of environmental health, which results in low active participation in managing environmental sanitation. Furthermore, standard operating procedures for hygiene and sanitation in the village do not exist and have never been established. For this reason, community service activities were carried out with the aim of increasing awareness, knowledge and the level of active participation of the community in managing environmental health in Gegutu Reban Hamlet, Dasan Griya Village, West Lombok. The activities were carried out using lecture, focused groupe discussion, demonstration, practice and ongoing mentoring methods for the target audience, which included housewives, farmer representatives and youth representatives. The monitoring results showed that participants were very enthusiastic about participating in this activity. Participants' awareness and knowledge about maintaining environmental health increased. The accuracy of participants' skills in carrying out several practiced hygiene and sanitation actions also increased. This activity also produced a draft SOP for hygiene and sanitation management that can be implemented by local residents, especially in Gegutu Reban Hamlet, Dasan Griya Village, West Lombok.

Abstract

The problem of organic waste in the environment can be overcome by using organic waste bioconversion technology using maggots. This technology produces a by-product in the form of leachate that can be used as Liquid Organic Fertilizer (POC). On the other hand, research on the effect of maggots on the quality and quantity of POC produced has not been widely studied. This study aims to 1). determine the quality of POC based on the concentration of N, P and K; 2). Determine the quantity of POC based on the volume of POC. The method used is an experimental method with the treatment of organic waste conversion using maggots (M1) and without maggots (M0). Each treatment was repeated 4 times. Data were analyzed using the t-independent test with the help of the SPSS version 22 application. The time of this research was carried out in May 2024 - July 2024. The location of the research was carried out at the Lingsar Regional Integrated Waste Processing Site (TPSTR) and the Soil Chemistry Laboratory of the University of Mataram. The results of this study indicate that the quality of liquid organic fertilizer (POC) in M1 is better than M0. The content of N (nitrogen), P (phosphorus) and K (potassium) in M1 were 0.14%, 0.11%, and 0.17% respectively, while M0 was 0.11%, 0.06%, and 0.09% respectively. The t-independent test showed that there was a significant difference between M0 and M1. The content of N, P and K in this study was still below the standard quality values ​​based on the Decree of the Minister of Agriculture of the Republic of Indonesia Number 261/KPTS/SR.310/M/4/2019 concerning Minimum Technical Requirements for Organic Fertilizers, Biological Fertilizers and Soil Improvers.
