Abstrak Air limbah yang dihasilkan selama proses produksi batik mengandung bahan kimia beracun dan sulit terurai yang dapat menyebabkan meningkatnya BOD, COD, TSS, pH maupun logam berat. Air limbah yang dihasilkan dari batik atau industri tekstil umumnya merupakan senyawa organik yang sulit terurai, yang dapat menyebabkan pencemaran lingkungan, terutama dari lingkungan akuatik. Effluent dari industri batik pada proses boiling tidak memenuhi baku mutu yang telah ditetapkan oleh Permen LH RI No. 5 Tahun 2014. Sistem pengolahan air limbah alami seperti constructed wetlands (CWs) dan biological sand filter menjadi alternatif yang relevan dalam mengolah air limbah karena efisiensinya, biayanya maupun pengoperasiannya. Penelitian ini bertujuan untuk mengolah air limbah industri batik menggunakan integrasi biofilter dan CWs. Penelitian dilakukan dengan membuat skala kecil dari alat integrasi biofilter dan constructed wetlands yang kemudian dilakukan uji coba kinerja alat dengan mengalirkan sampel air limbah industri batik. Hasil penelitian menunjukkan efisiensi penurunan untuk masing-masing parameter COD, TSS, dan minyak & lemak sebesar 72,67-86,67%; 95,85-98,18%; dan 79,47-90,04%. Hasil penelitian menunjukkan bahwa air hasil pengolahan limbah industri batik masih melebihi baku mutu yang telah ditetapkan sehingga air hasil pengolahan tidak diperbolehkan untuk dibuang ke badan air. Air hasil pengolahan juga tidak dapat diperuntukkan oleh masyarakat karena tidak memenuhi kriteria mutu air pada kelas air yang ditetapkan. Penelitian lebih lanjut diperlukan untuk pemanfaatan air hasil pengolahan sebagai air bahan bangunan. Kata Kunci: limbah industri batik, boiling, biofilter, constructed wetlands Abstract Wastewater produced during the batik production process contains toxic and non-biodegradable chemicals resulting in high BOD, COD, TSS, pH and heavy metals. Wastewater generated from batik or textile industries is generally a non-biodegradable organic compound, which can cause environmental pollution, especially of the aquatic environment. Effluent from the batik industry during the boiling process did not meet the standard for discharged effluent in accordance with the Minister of Environment Regulation No.5 of 2014. Natural wastewater treatment systems such as constructed wetlands and biological sand filters are becoming an increasingly relevant alternative for treating wastewater due to its efficiency, low establishment costs and low operation and management requirements. This research aims to treat batik industry wastewater by using biofilter and CWs integration. The research was conducted by making a small scale from the biofilter and constructed wetlands integration, then tested by flowing samples of batik industry wastewater. The results indicated removal efficiency for each parameter of COD, TSS, and fat & oil amounts 72.67-86.67%; 95.85-98.18%; and 79.47-90.04%. The results showed that the treated water from batik industry waste processing still exceeds meet the standard for discharged effluent so that the treated water is not allowed to be discharged into water bodies. The treated water also cannot be used by the community because it does not meet the water quality criteria for the specified water class. Further research is needed for the utilization of treated water as building materials. Keywords: batik industry wastewater, boiling, biofilter, constructed wetlands

Batik merupakan warisan budaya asli Indonesia yang telah disahkan oleh UNESCO. Batik digunakan dalam berbagai kesempatan baik formal mapun non-formal. Hal ini berdampak positif pada perekonomian Indonesia dengan meningkatkan jumlah produksi, jumlah industri batik, dan penyerapan tenaga kerja. Industri batik juga berdampak negatif pada lingkungan karena limbah cair yang dihasilkan dari proses pembuatannya. Constructed wetland (CW) merupakan salah satu solusi yang ditawarkan sebagai teknologi yang mudah, murah, dan berkelanjutan sebagai unit pengolahan limbah dengan memanfaatkan teknologi alami. Tanaman yang digunakan adalah tanaman Canna indica. Tanaman ini telah banyak digunakan karena tanaman ini dapat mentoleransi limbah dengan kandungan timbal yang tinggi. Hybrid constructed wetland merupakan gabungan antara horizontal dan vertical subsurface flow CW. Teknologi ini diaplikasikan untuk mengolah limbah cair hasil perebusan batik (boiling). Parameter yang diteliti adalah Chemical Oxygen demand (COD), Total Suspended Solid (TSS), dan Fat, Oil, and Grease (FOG) dengan lama limbah berada direaktor (Hydraulic Retention Time) selama 3,5,dan 7 hari. Removal efficiency yang dapat dicapai untuk COD sebesar 89,61% dan FOG 89,53% pada hari ke 3. Removal efficiency paling optimal untuk TSS sebesar 98,74% pada hari ke 5. Kata kunci : limbah industri batik, limbah boiling, hybrid CW, canna indica, hydraulic retention time (HRT)

Salah satu wilayah di provinsi Jawa Timur yang menjadi penghasil kopi adalah Kelurahan Pecalukan yang terletak di Kecamatan Prigen. Tanaman kopi yang dibudidayakan di wilayah ini memiliki keunggulan cita rasa yang tinggi karena berada di lereng pegunungan Welirang. Namun demikian, Gabungan Kelompok Petani (Gapoktan) yang membudidayakan tanaman kopi dan industri kecil yang mengolah buah kopi hasil panen di wilayah Pecalukan ini belum memahami pentingnya produksi ramah lingkungan. Mayoritas sisa panen dan olahan produksi kopi dibuang begitu saja di lahan terbuka. Hal tersebut berlawanan dengan kondisi lingkungan di sekelilingnya yang sangat indah. Oleh karena itu, tujuan dari pemberdayaan masyarakat ini adalah untuk mengembangkan edu-ekowisata kopi binaan di wilayah Pecalukan, Prigen melalui pelatihan masyarakat dalam membangun industri kecil yang zero waste serta menciptakan peluang tambahan pendapatan bagi masyarakat. Metode yang digunakan pada kegiatan ini meliputi sosialisasi dan edukasi, diskusi, rancang bangun, dan pelatihan serta pendampingan. Hasil dari kegiatan ini berupa rancang bangun ipteks komposter serta adanya peningkatan pemahaman masyarakat dalam pembuatan pupuk kompos, body scrub, serta sabun dari limbah kulit kopi.

The lack of understanding among the community in preparing the Budget Plan (RAB) for construction projects often creates obstacles in project implementation in Kelurahan Ketintang, Surabaya. The Community Service Program (PKM) by Universitas Negeri Surabaya (UNESA) aims to enhance the understanding of the community in RT.03 RW.04 Kelurahan Ketintang in preparing the RAB using Microsoft Excel. This program is conducted in three stages: introduction and socialization, technical guidance, and evaluation. The results indicate an improvement in participants' understanding, with the average score increasing from 42.37 in the pre-test to 63.37 in the post-test, reflecting an average increase of 20.99%. This demonstrates that the program is effective in assisting the community to understand and apply the preparation of the RAB more accurately and efficiently. The program is also expected to support better local infrastructure development and strengthen the relationship between the university and the community.

In accordance with Presidential Instruction (Inpres) Number 9 of 2016 concerning the Revitalization of Vocational High Schools (SMK) in the context of Improving the Quality and Competitiveness of Indonesian Human Resources (HR), it is necessary to compile a map of labor needs for SMK graduates according to their respective duties, functions, and authorities based on the road map for vocational development. One of the targeted developments is the skill of using computer applications in accordance with its basic competencies. Currently, engineering mechanics lessons at SMKN 2 Surabaya are only given theoretically. The use of computer applications to help solve existing problems has not been implemented. Even though work challenges today really require these skills to solve more complicated problems, more quantities, and faster solutions. Based on the above, this PKM activity aims to improve students' ability to use SAP2000 applications to solve engineering mechanics problems. The training provided includes an introduction to the basic use of SAP2000 including the use of the menus in it. Followed by the practice of working on example problems along with discussing their theoretical validation. After that, exercises for more complicated problems are given which end with giving quizzes to further motivate students. From the post-test results given at the end of the training, the results showed that 85.58% of trainees could understand the training material well. This shows that this training is very effective in improving students' abilities which is expected to bring benefits as a provision to face work challenges after graduation.
