Environmental sustainability influenced social and economy sustainability. Without sustainably productive environment to provide resource foundation, it would difficult having sustainable society. Sustainable economy depends on sustainable raw material, energy and environmental resources. This work discussed about environmental sustainability in marine especially utilizing sea water as raw material for salt. This work started to investigate raw material characteristics and salt quality. The raw material characteristics represented high concentration for sodium, chloride, calcium and polluted by trace metal. According SEM-EDX result, salt contains lead and cooper. Salt farmer income is influenced by the salt quality, the higher its quality the bigger income received. Indirectly, economy in coastal was influenced by sea water quality. This is what encourages the research to achieve marine environmental sustainability in coastal area. The aims of this study are to review and categorize indicator for marine environmental sustainability into Driver-Pressure-States-Impacts-Response (DPSIR) and provide strategies suggestion for support environmental sustainability.  DPSIR indicators are utilizing sea water, wastewater discharge into sea, increasing of sea water ion concentration, mangrove growth disruption, regulation for salt wastewater disposal direct to the sea. Recovery magnesium from salt wastewater is potential strategy to protect marine environment and to support economy-social sustainability.

Pineapple leaf waste (Ananas cosmosus) contains a constituent component in the form of cellulose and lignin. Cellulose, hemicellulose and lignin bind to each other to form lignocellulose. The high cellulose content can be used as an adsorbent through the process of delignification or removal of lignin. This study aims to determine the characteristics and ability of pineapple leaf cellulose to remover heavy Cu metals. Pineapple leaves to be used are equalized to 60 mesh then delignified for 70 and 90 minutes by mixing pineapple powder using 9% NaOH with a ratio of 1:30 (w/v). Pineapple leaves are characterized by chesson, SEM, and XRD analysis. The results of chesson showed that pineapple leaf cellulose had a cellulose content of 25.33% and the delignification time of 70 minutes resulted in the highest cellulose content of 59.12%. The XRD diffractogram showed pineapple leaf cellulose including type I cellulose. The highest degree of crystallinity was obtained by pineapple leaf cellulose with a delignification time of 90 minutes which was equal to 65.98%. The adsorption process is observed with variations in contact time 30; 60; 90; 120 minutes. The highest Cu metal adsorption is pineapple leaves with a delignification process of 70 minutes with a contact time of 90 minutes.

Pola perusahaan dalam memenuhi permintaan pasar disisi lain juga mengakibatkan timbulnya dampak lingkungan yang disebabkan oleh proses produksi. Tujuan dari penelitian ini adalah untuk mengetahui dan mengidentifikasi besarnya dampak lingkungan yang ditimbulkan adanya proses produksi minyak goreng sawit. Perusahaan ini juga telah menerapkan sistem manajemen lingkungan sebagai bentuk tanggung jawab serta upaya untuk memperbaiki lingkungan. Salah satu upaya dalam memperbaiki lingkungan yaitu dengan melakukan penilaian siklus hidup. Penilaian siklus hidup adalah salah satu metode yang dapat mengidentifikasi dampak lingkungan yang disebabkan oleh proses produksi dan dinilai lebih sistematis mengeluarkan dampak terhadap lingkungan. Hasil analisis menggunakan pendekatan penilaian siklus hidup ini dapat mengetahui titik kritis (Hotspot) yang menyebabkan dampak lingkungan, baik dari proses produksi maupun produknya, sehingga didapatkan beberapa alternatif rekomendasi. Penentuan alternatif rekomendasi terbaik menggunakan metode Analytical Network Process (ANP). ANP merupakan salah satu metode untuk mengukur skala prioritas dalam mengambil suatu keputusan. Hasil dampak lingkungan menggunakan pendekatan daur hidup dengan metode CML-IA Baseline adalah Abiotic Depletion (fossil fuels) 12,56 MJ/ Ton, Pemanasan Global 0,00117 kg CO2 eq/ Ton, Toksisitas pada manusia 0,03718 kg 1,4 -DB eq/ Ton, Oksidasi Fotokimia 0,00043 kg C2H4 eq/ Ton, Asidifikasi 0,02586 kg SO2 eq/ Ton, dan Eutrofikasi 0,00394 kg PO4/Ton. Sedangkan hasil keputusan dari berbagai alternatif dan kriteria dengan metode ANP disimpulkan bahwa alternatif penggunaan biomassa tandan kosong atau empty fruit bunch (EFB) sebagai bahan bakar Boiler dan kriteria dampak lingkungan sebagai prioritas utama dalam perbaikan lingkungan.ABSTRACTPalm oil production increases along with the many people's demand. Such rapid improvements affect the performance systems of the company. The company's pattern of meeting market demand on the other hand also resulted in the onset of environmental impacts caused by the production process. The purpose of this study is to find out and identify the magnitude of the environmental impact caused by the palm oil production process. The company has also implemented an environmental management system as a form of responsibility as well as an effort to improve the environment. One of the efforts in improving the environment is to conduct a life cycle assessment. Life cycle assessment is one method that can identify the environmental impact caused by the production process and is considered more systematically issuing an impact on the environment. The results of the analysis using this life cycle assessment approach can find out the critical point (Hotspot) that causes environmental impact, both from the production process and the product, so that several alternative recommendations are obtained. The best alternative recommendations are determined using the Analytical Network Process (ANP) method. ANP is a method for measuring the scale of priority in making a decision. The result of environmental impact with CML-IA Baseline method is Abiotic Depletion 12,56 MJ/ Ton, Global Warming 0,00117 kg CO2 eq/ Ton, Human Toxicity 0,03718 kg 1,4 -DB eq/ Ton, Photochemical Oxidation 0,00043 kg C2H4 eq/ Ton, Acidification 0,02586 kg SO2 eq/ Ton, and Eutrophication 0,00394kg PO4/ Ton. While the results of decisions from various alternatives and criteria with the ANP method concluded that the alternative use of empty fruit bunch (EFB) as boiler fuel and environmental impact criteria as the main priority in environmental improvement.

Amonia merupakan bahan kimia bahan berbahaya dan beracun, dapat menimbulkan luka bakar bahkan kematian. Pelepasan amonia dari tangki penyimpanan memiliki potensi bahaya bagi pekerja dan manusia di lingkungan sekitar. Amonia cair mudah terlepas ke lingkungan karena dapat berubah menjadi gas pada temperatur ruang. Penelitian dilakukan untuk menganalisis risiko tinggi dan menentukan basic cause kebocoran pada tangki penyimpanan. Analisis risiko tinggi akan didahului dengan identifikasi potensi bahaya menggunakan metoda Failure Mode Equipment Analysis (FMEA). Untuk mengetahui basic cause dilakukan menggunakan Fault Tree Analysis (FTA). Hasil FMEA didapatkan risiko tertinggi adalah fail close flow control valve. (FCV). Hasil FTA basic cause dari fail close FCV adalah perawatan buruk, umur pemakaian, pressure indicator error/jarang dikalibrasi. Pencegahan kegagalan semua komponen yang mendukung kinerja FCV adalah perawatan sesuai jadwal agar dapat mencegah kerusakan sebelum masa efektif komponen. Selain perawatan sesuai jadwal juga dilakukan pelatihan kepada operator agar kompeten untuk mengurangi human error.

Salah satu teknologi robotika yang banyak digunakan adalah robot penjejak garis atau yang lebih sering disebut robot line tracer atau line follower. Selain dimanfaatkan untuk membantu pekerjaan, robot juga menjadi salah satu kegiatan ekstrakurikuler di tingkat Sekolah Dasar (SD). Kegiatan ekstrakurikuler robotika memberikan dampak positif terhadap ketrampilan berpikir kreatif siswa usia SD. Selain itu, mempelajari robotika berhubungan dengan pelajaran matematika, fisika, sain dan teknologi, dan komputer dan pemrograman. Madrasah Ibtidaiyah (MI) Muhammadiyah 27 Surabaya merupakan salah satu sekolah dasar modern yang berbasis pesantren yang berlokasi di Rungkut, Surabaya. Ektrakurikuler Robotika pada madrasah ini berdiri sejak Desember 2018. Karena termasuk ektrakurikuler baru, maka untuk prestasi mungkin masih sebatas keberhasilan pembuatan robot line tracer analog (LTA) setelah beberapa bulan mengikuti kegiatan ekstra. Selain itu untuk fasilitas yang disediakan pun masih terbilang cukup minim untuk kegiatan belajar mengajar sehingga agak sulit menyampaikan materi robotika yang cukup berat jika tidak diimbangi dengan peralatan dan fasilitas yang memadai. Pada pengabdian masyarakat ini dilaksanakan kegiatan pelatihan robot LTA untuk siswa MI Muhammadiyah 27 Surabaya. Kegiatan terdiri dari penyampaian materi dan praktik. Kegiatan diikuti oleh beberapa siswa dan guru dari semua tingkatan kelas. Terdapat lima robot yang berhasil dirakit untuk diuji pada lintasan yang telah disediakan.

One of the supporting facilities for operational activities at the Tanjung Perak Port is the existence of adequate green open spaces. The type of plant that is widely planted is the Angsana tree. Since 2018, this port has had an innovation to reuse waste from trimming activities to become compost, but the results are not optimal because there is still a lot of compost in the form of whole leaves. In this research, the composting method will be tested using Black Soldier Fly larvae and local microorganisms from banana hump. Compost material in the form of the waste of Angsana leaves is mixed with the waste of mackerel fish which comes from processing activities of mackerel fish food. Variations were made with different feeding regimes for Black Soldier Fly larvae, namely 3 weekly, daily, and weekly with dose of local microorganism banana hump as much as 15 mL/kg. The results of composting showed that the variations of feeding regime have significant effect for compost quality.
