Abstract

Eco enzyme merupakan produk pengolahan limbah rumah tangga yang berasal dari sisa sayuran atau buah-buahan. Eco enzyme dapat dijadikan sebagai bahan aktif untuk membuat produk kebersihan rumah tangga diantaranya detergen cair ramah lingkungan. Pembuatan detergen cair berbasis eco enzym memiliki peluang untuk dijadikan sebagai kegiatan home industry. Tujuan kegiatan ini adalah memberikan pelatihan kepada kelompok PKK Desa Rejomulyo dalam pembuatan detergen cair ramah lingkungan dengan bahan aktif eco enzyme. Tahapan pelaksanaan kegiatan terdiri dari ceramah, tanya jawab serta pelatihan pembuatan detergen cair. Hasil kegiatan diperoleh produk detergen cair ramah lingkungan yang dapat dikonsumsi oleh masyarakat di Desa Rejomulyo. Detergen cair ramah lungkungan yang dihasilkan dari kegiatan ini diharapkan menjadi nilai tambah bagi anggota PKK untuk mengembangkan produk usaha ekonomi kreatif berbasis home industry. Hasil akhir dari pengabdian ini adalah terwujudnya usaha industri rumah tangga berbasis eco enzyme dan diperolehnya variasi produk kebersihan rumah tangga dari PKK Desa Rejomulyo.

Abstract

Telah dilakukan penelitian penggunaan material aluminasilikat MCM-41 sebagai adsorben limbah cair tapioka. Dalam penelitian ini dipelajari permodelan isotermal dan kinetika adsorpsi dari material MCM-41 pada proses adsorpsi limbah cair tapioka. Isotermal Langmuir dan Freundlich digunakan sebagai permodelan isotermal data penelitian. Dari data penelitian yang diperoleh pada konsentrasi COD sebesar 416 - 784 mg/L, proses adsorpsi limbah cair tapioka oleh MCM-41 sesuai dengan pendekatan isothermal Langmuir. Kapasitas maksimum adsorpsi MCM-41 diperoleh dari pendekatan Langmuir adalah sebesar 15,92 mg/g. Model kinetika pseudo-orde pertama dan pseudo-orde kedua digunakan untuk analisis kinetika adsorpsi pada data penelitian. Model kinetik pseudo-orde pertama yang sesuai dengan proses adsorpsi limbah cair tapioka dengan laju penyerapan adalah 7,48 x 10-2 dan 7,37 x 10-2 g/(min-mg) untuk konsentrasi awal secara berturut-turut adalah 608 dan 784 mg/L.

Abstract

Pertukaran ion antara Cr3+ dan H+ menggunakan zeolit sebagai penukar ion adalah salah satu metode untuk memurnikan air dari ion kromium. Zeolit adalah senyawa aluminosilikat tetrahedral dengan struktur ikatan 3-dimesi, memiliki pori bagian dalam, dan luas permukaan yang tinggi, karena itu dapat digunakan sebagai adsorben. Tujuan penelitian ini adalah untuk mengevaluasi pengaruh waktu kontak optimum, suhu, dan konsentrasi kromium terhadap kapasitas penyerapan. Tahap pertama adalah mencampur zeolit yang telah diaktifkan dengan larutan kromium (10 ppm kromium) dalam tangki berpengaduk pada 25oC. Selanjutnya larutan diambil setiap 60 menit hingga konsentrasi residu larutan kromium konstan. Proses adsorpsi dilangsungkan pada suhu berbeda yaitu: 25, 30, 35, 40, 45, dan 50 oC. Untuk uji adsorpsi isotermal, pada suhu dengan hasil penyerapan terbaik divariasikan konsentrasi kromiumnya yaitu: 10, 20, 40, 60, dan 100 ppm. Dosis adsorben yang digunakan adalah 3 gram adsorbent/200 mL larutan krommium dengan kecepatan pengaduk 240 rpm. Larutan kromium dideteksi dengan menggunakan Atomic Absorption Spectroscopy (AAS) atau Spektroskopi Serapan Atom. Waktu kontak optimum diperoleh 3 jam menggunakan zeolit yang diaktifkan dengan asam, diperoleh nilai adsorpsi optimum 99,275%. Proses adsorpsi berjalan secara eksoterm, memiliki ?Ho = -3.9574,6 J/mol dan ?So = -117.227 J/moloK. Model isotermal adsorpsi mengikuti isoterm Freundlich menurut persamaan Qe = 0,044463C1/2,5125, kapasitas penyerapan Kf = 0,044463 mmol/gram adsorben, dan intensitas adsorpsi n = 2,5125.

Abstract

Ion exchange process between ion NH4+ and H+ by using zeolite as its ion exchanger is one of methods to purify water from ammonium ion content. Natural zeolites are chosen as ion exchanger because it is abundantly provided in Indonesia, especially in Lampung. The influences of reaction temperature and stirrer speed toward reaction rate constant, mass transfer coefficient and effective diffusivity in batch ion exchange process, were analysed by using shrinking core model. Processes run by mixing zeolite and ammonium solution in a stirred tank at 30, 40 and 50oC with stirrer speed variation of 700, 800 and 900 rpm. Every 5 up to 60 min, the sample was taken for ammonium ion analyses. The results show that mass transfer, intraparticle diffusion and ion exchange reaction resistance influenced the overall rate of reaction. The results also show that reaction temperature and stirrer speed influenced the reaction rate constant, mass transfer coefficient and effective diffusivity. The correlations of them are stated in simple empirical equation. Shrinking core model was good to describe the ion exchange kinetics between NH4+ and H+ ion in natural zeolite from Lampung with the average error range of 1,15 % 3,71%.Keywords: ion exchange kinetics, Lampung natural zeolite, shrinking core model.

Abstract

This community service aims to help the UMKM engaged in the food industry in Sidosari Village, Natar District, South Lampung Regency (partners). Partners never replace used cooking oil (waste cooking oil) with new ones, but only add new oil to used cooking oil for frying the next food. Partners consider that using used cooking oil from branded cooking oil will be safe to use many times, thereby saving on expenses without knowing the consequences. This understanding is due to the partner's low level of awareness. Therefore, the community service (PkM) is very appropriate for understanding partners about the dangers of waste cooking when used repeatedly without ever being replaced with a new one. The methods used in this service include: socialization, training, and direct practice of processing and making eco-friendly handmade solid laundry soap from used cooking oil. Socialization has been explained the dangers of using cooking oil for health and the environment. Training and practice were provided to partners on how to process and make eco-friendly handmade solid laundry soap made from used cooking oil and bath soap from new oil for household use and even for sale. After participating in this service, residents and the UMKM in particular no longer used cooking oil repeatedly to fry their products to increase product quality. They are enthusiastic to continuously make solid soap from used cooking oil for washing purposes and even make it from new oil for bath soap purposes. Thus, it will save the cost of shopping for laundry soap and bath soap reduce dependence on manufacturer's soap so that the environment is not polluted by detergent waste. It can even be an additional income for those who are serious about getting into the business of making this laundry soap and environmentally friendly homemade bath soap.

Abstract

The Biogas-based energy security program in Kediri Village, Pringsewu District, Lampung Province, aims to provide awareness and knowledge to villagers about the potential of cow dung to be made into biogas and promote awareness of good environment quality. An evaluation of the sustainability of the program in the community was conducted. The methods that were used in this program are (1) socialization to provide awareness of good environment quality and energy security, (2) digester construction and stove and biogas lamp installation, which was carried out by the community together with certified trainers, (3) creation of a master design of the digester layout to ensure the maximum utilization of the digesters, and (4) evaluation to determine opportunities for program sustainability. Results show that the Biogas-based Energy Security Program has succeeded in making the community aware of and accept and apply the technology of processing cow manure into biogas. Biogas has met 100% of the fuel needs for cooking and electricity of biogas-fed houses. The environment quality has also improved, as shown by clean cages and home environments, and methane emissions have reduced. Over the five-year program, 11 out of 20 planned digesters have been built. The program's future sustainability can be continued by the community, provided that alternative sources of funds that can be pursued by the community are available.
