Abstract

Abstrak: Desa Dangiang memiliki sumberdaya kelapa yang melimpah tetapi harga jual kelapa yang sangat rendah. Masyarakat terbiasa membuat minyak kelapa untuk kebutuhan sehari-hari. Pelatihan pembuatan sabun berbahan minyak kelapa dimaksudkan untuk meningkatkan nilai jual kelapa sehingga dapat menambah penghasilan masyarakat. Metode pembuatan sabun yang dipraktikkan adalah metode cold proses dengan dua pilihan resep sabun, yakni 100% minyak kelapa dan campuran minyak kelapa, minyak kelapa sawit, dan minyak zaitun. Serbuk kelor ditambahkan karena selain berkhasiat sebagai antioksidan juga sebagai pewarna alami. Hasil pelatihan berupa sabun  batang. Tanggapan masyarakat setelah menggunakan sabun buatan tersebut sangat positif, karena nyaman dipakai dan disukai oleh masyarakat. Sabun tersebut juga tidak mengandung bahan berbahaya seperti dietanolamine (DEA), Sodium Lauryl Sulfate (SLS), dan Triclosan. Ketertarikan masyarakat terhadap sabun tersebut menumbuhkan minat masyarakat untuk dapat memproduksi sabun sendiri dan berharap sabun tersebut dapat di perdagangkan sehingga dapat menambah pendapatan masyarakat. Abstract:  Dangiang Village has abundant coconut resources, but the selling price is meager.

Abstract

Indonesia adalah salah satu negara yang memiliki berbagai macam potensi bencana seperti gempa bumi. Salah satu kejadian gempa bumi dengan kekuatan yang mencapai 6,8 Skala Richter (SR) terjadi di pulau Lombok Provinsi Nusa Tenggara Barat (NTB). Komponen penting yang sangat berperan dalam manajemen bencana adalah distribusi bantuan paska bencana. Program Pengabdian Masyarakat (PKM) dengan tema kebencanaan diinisiasi oleh Universitas Muhammadiyah Mataram. Sejumlah 30 mahasiswa dikirim untuk membantu program distribusi bantuan paska gempa di dua simpul pengelolaan bantuan yaitu Muhammadiyah Managament Disaster Center (MDMC) yang bertempat di Gedung Dakwah Pengurus Wilayah Muhammadiyah (PWM) NTB dan Badan Penanggulangan Bencana Daerah (BPBD) yang bertempat di kantor BPBD NTB. Dari kegiatan ini disimpulkan bahwa tata kelola dan strategi dalam pengelolaan distribusi bantuan bencana yang dilakukan oleh MDMC dan BPBD memiliki karakteristik yang berbeda, hal ini terkait dengan ‘payung’ operasional yang diacu oleh kedua lembaga tersebut. Beberapa karateristik perbendaan tersebut adalah sumber dana, sistim koordinasi, dan sumberdaya yang pada akhirnya menghasilkan perbedaan dalam alur distribusi.Kata Kunci: Bencana; BPBD; Distribusi Bantuan; MDMC; Paska Gempa Learning from Disaster Community Service: Distribution Pattern of Post-Lombok Earthquake Aid between MDMC and BPBDABSTRACTIndonesia is one the countries that has various potential disasters such as the Earth Quake. One of the Earth Quakes that reached magnitude of 6.8 Richter Scale (SR) was occurred at Lombok Island Province of West Nusa Tenggara (NTB). A critical component that plays in the disaster management is humanitarian logistic supply. The community services program (PKM) with disaster theme was initiated by Universitas Muhammadiyah Mataram. Total of 30 students were sent for assisting the humanitarian logistic supply post-earth quake at two main distribution focal point, namely Muhammadiyah Disaster Management Centre that located at Gedung Dakwah Pengurus Wilayah Muhammadiyah (PWM) NTB, and The Provincial Disaster Management Office (BPBD) that located at BPBD NTB office. The PKM concluded that the distribution of humanitarian logistic by MDMC and BPBD has different characteristic associated with management and strategy, these differences occurred due to operational guideline that referred by those two institution. Some of the characteristic differences include funding resource, coordination system, and human resources that generated the different distribution flow.         Keywords: Disaster; BPBD; Distribution Aid; MDMC; Post Earth Quake

Abstract

Climate change is one of the world’s problems that must be dealt; the failure in tackling climate change will impact on increasing the earth temperature and endanger the archipelago countries including Indonesia. Clean Development Mechanism (CDM) is one of the Kyoto Protocol mechanisms designed to mitigate climate change. Indonesia is one of the countries that meets the requirement as the host of CDM program and has set up the target to reduce GHG emissions as much as 26 percent in year 2020. The industrial sector has opportunities to engage actively in reducing GHG emission including mining industry.  The objectives of this research are to find out the potency of mining company’s involvement in climate change mitigation efforts particularly through CDM. In addition, the research of method that is chosen is literature study including reviewing data relating to CDM and with qualitative approached. The result shows that mining industry has a potency to involve actively in CDM program, among others, through energy efficiency, fuel substitution, renewable energy, Coal Bed Methane and the handling of critical lands through afforestation and reforestation scheme. Furthermore, by using Business as Usual assumption, the linier  regression that is produced y=27.255.x + 12.711 therefore  It is estimated that about 15 Mt CO2-e (assuming 4 percent reduction) needs to be derived from the energy sector in 2020 that can be taken as an opportunity for the mining industry as well.

Abstract

Climate change is one of the global issues that require the participation of all stakeholders for handling. In addition, the climate change issue is listed as one of the sustainable development goals (SDGs). The Government of Mataram city, as one of the stakeholders, has committed to involve the climate change consideration into its planned program, including the development of agro-edutourism facility. This study aims to calculate a carbon footprint of agroedutourism facility during the operational stage in order to implement the Greenhouse Gas (GHG) emission reduction strategy. The method used is a life cycle assessment approach with ReCiPe analysis, and the functional unit is an annual carbon footprint per m2 area of agro-edutourism. The study showed that the total carbon footprint per m2 was 2.88 KgCO2-e per annum with the primary environmental hotspot was fossil fuel utilization in energy source of agro-edutourism facility (Electricity State-own Company) and visitor vehicles. Therefore, some strategies could be applied for reducing the carbon footprint, such as increasing the utilization percentage of renewable energy (solar panel), using energy-saving bulbs, preparing the facilities for zero-emission vehicles, and applying the green building concept or design. Further research is required to assess the energy management concept from the technical feasibility aspect and economic aspect for complimenting this study.

Abstract

Pupuk urea adalah merupakan salah satu jenis pupuk yang paling banyak digunakan oleh petani di Indonesia. Total penggunaan pupuk urea selama tahun 2018 yang tercatat pada Kementerian Perindustrian Indonesia adalah sejumlah 6,27 Juta ton atau mengalami peningkatan 5% dari tahun sebelumnya. Salah satu pabrik yang menghasilkan pupuk urea adalah PT Pupuk Kujang di Cikampek Jawa Barat. Tujuan dari studi ini adalah untuk mengidentifikasi dampak lingkungan potensial yang dihasilkan dari produksi 50 Kg pupuk urea. Metode yang digunakan dalam kajian dampak daur hidup (Life Cycle Impact Assessment) adalah CML-IA dengan 11(sebelas) parameter yaitu abiotic depletion dan abiotic depletion (fossil fuel), global warming (GWP100), ozone layer depletion, human toxicity, fresh water dan marine aquatic ecotoxicity, terrestrial ecotoxicity, photochemical oxidation, acidification, dan eutrophication,  Adapun batasan sistem menggunakancradle to grave yang memperhitungakn bahan dasar, proses produksi, transportasi dan pengelolaan limbah (karung bekas pupuk). Dari hasil analisa didapatkan bahwa proses produksi memberikan kontribusi dampak paling besar dibandingkan dengan pengelolaan limbah sisa karung (landfill). Proses produksi memberikan kontribusi terhadap dampak potensial lingkungan pada kisaran 99,14 – 100 persen dari total dampak yang di hasilkan. Sebagai tambahan bahwa dampak yang ditimbulkan pada proses di pabrik ammonia akan memberikan kontribusi lebih besar pada kisaran 22-37 persen lebih besar dibandingkan dengan proses di pabrik urea.Dari hasil analisa dengan memanfaatkan grafik jaringan (networking graph) pada program SimaPro juga menunjukkan bahwa environmental hotspotsdari daur hidup pupuk urea disebabkan oleh penggunaan gas alam, katalis molybdenum, penggunaan listrik dari Perusahaan Listrik Negara (PLN), penggunaan polypropylene dalam material karung, dan transportasi. Dengan mempertimbangan environmental hotspot maka tindakan perbaikan berkelanjutan perlu dilakukan baik berupa  audit energi maupun pengelolaan penggunaan katalis.

Abstract

Mangroves have various functions and roles, both economic and ecological. In Jerowaru District, East Lombok Regency, the function and role of mangroves are economically and ecologically beneficial, but their value has not been measured. This study aims to determine the valuation of direct benefits of mangroves in Jerowaru District, East Lombok Regency. The approach taken in determining the economic value of mangrove products and services is financial analysis and economic analysis. In financial analysis, a direct approach is used, namely by using market values for marketed commodities and determining the value of substitutes for goods and services that are not marketed. While in the economic analysis, the shadow price or accounting price, namely the value adjusted in such a way as to describe the true value of mangrove goods and services. The results showed that the value of the direct benefit of mangroves in the study area was ± IDR 88.162.750/ha/year. Valuation of the value of direct benefits of mangroves at the location comes from mangrove products and services in the form of firewood and charcoal products, construction wood, capture fisheries products, fish and shrimp larvae stocks, wildlife, preservatives and dyes, food ingredients, and medicines, animal feed, salt, recreation, and tourism, as well as education and research.
