Abstract

Abstract: Water scarcity phenomenon during the dry season due to the diminishing groundwater sources (wells) is frequently observed in urban residential areas. On the other hand, heavy rainfall with high intensity leads to flooding and frequent disasters during the rainy season. Rainwater harvesting systems are simple, inexpensive, and do not require specialized skills or knowledge, but they are not widely practiced by the community. The practice of rainwater harvesting is important as an alternative water source to meet daily needs. There are three basic components that should be present in a rainwater harvesting system: 1) catchment, which is the rainwater collection surface such as rooftops; 2) delivery system, which is the system for channeling rainwater from the roof to the storage container through gutters; and 3) storage reservoir, which is the place to store rainwater such as a tank, which is then directed to a storage tank for electrolysis to obtain bacteria-free water and water with high pH content that can be consumed safely and healthily. Rainwater harvesting activities are carried out in one of the houses in Villa Mutiara Housing, Sawah Baru Village, Ciputat Subdistrict, South Tangerang City. This activity results in the local community utilizing the processed (electrolyzed) rainwater for safe and healthy consumption.Abstrak: Fenomena kekeringan/ kekurangan air saat musim kemarau karena sumber air tanah (sumur) yang semakin berkurang sering terjadi di wilayah perumahan perkotaan. Di sisi lain, hujan deras yang mengguyur dengan intensitas tinggi mengakibatkan banjir dan menimbulkan bencanasering terjadi saat musim penghujan. Sistem pemanen air hujan merupakan teknik yang sederhana, murah dan tidak membutuhkan keahlian atau pengetahuan khusus, namun belum banyak dilakukan oleh masyarakat. Praktek memanen air hujan penting sebagai alternatif sumber air untuk memenuhi kebutuhan sehari-hari. Terdapat  tiga komponen dasar yang harus ada dalam sistem pemanen air hujan yaitu: 1) catchment, yaitu penangkap air hujan berupa permukaan atap; 2) delivery system, yaitu sistem penyaluran air hujan dari atap ke tempat penampungan melalui talang; dan 3) storage reservoir, yaitu tempat penyimpan air hujan berupa toran yang selanjutnya disalurkan ke bak penyimpan  untuk dielektrolisis guna mendapatkan air bebas  dari bakteri dan mendapatkan air dengan kandungan pH tinggi untuk dapat dikonsumsi dengan aman dan sehat.Kegiatan pemanen air hujan dilakukan di salah satu rumah warga di Perumahan Villa Mutiara, Kel. Sawah Baru, Kec. Ciputat, Kota Tangerang Selatan. Hasil dari kegiatan ini, warga masyarakat setempat dapat memanfaatkan air hujan yang telah diolah (elketrolisis) untuk dikonsumsi dengan aman dan sehat.

Pemberdayaan pesantren dilakukan melalui kegiatan pelatihan pengembangan usaha dan pembuatan sabun cuci tangan dan mandi cair kepada para santri dan pengelola pesantren. Tujuan kegiatan pengabdian adalah memberikan pengetahuan dan ketrampilan usaha sabun cair untuk cuci tangan dan mandi kepada para santri dan pengelola pesantren. Pelatihan dilaksanakan di Pesantren Hurriyatul Amin, Kec. Parung, Kabupaten Bogor pada tanggal 22 Pebruari 2024. Peserta pelatihan sebanyak sembilan santri (3 pria dan 6 perempuan) dan satu orang pengelola pesantren. Sebelum pelaksanaan pelatihan dilakukan pre-test kepada peserta dengan nilai rata-rata 60 dan setelah pelaksanaan pelatihan diberikan post-test dengan nilai rata-rata 80 atau kenaikan kemampuan pengetahuan dan ketrampilan (kognitif dan psikomotorik) sebesar 20 poin. Secara umum dapat disimpulkan bahwa pelaksanaan pelatihan usaha pembuatan sabun cuci dan mandi cair berjalan dengan baik, dari aspek kognitif terdapat peningkatan cukup signifikan, sedangkan dari aspek ketrampilan terlihat peserta mampu/ terampil membuat sabun cuci dan mandi cair sesuai standar produk yang baik.Kata Kunci : Pesantren Huriyyatul Amin., Kewirausahaan Pesantren., Pelatihan Santri.,  Pembuatan Sabun Cair

Abstract

Batteries made from lithium, nickel, manganese, and cobalt are widely used, especially in the electrical industry, because they have high specific capacity, high safety, and low production costs. According to the International Energy Agency (IEA), the consumption of batteries used for electric vehicles will increase from 8 million in 2019 to 50 million in 2025 and to 140 million in 2030. As a result, the waste produced is also increasing. This type of lithium ion battery (LIB) which contains heavy metal elements such as nickel, manganese and cobalt can be recycled. This research aims to calculate the mass balance of the recycling process for nickel manganese cobalt (NMC) battery cathodes.   The processing process begins with mixing, leaching, filtration, drying the results of the filtration process, molarity adjustment, Flame Assisted Spray Pyrolysis, and calcination. Based on the results of mass balance calculations for the NMC recycle battery cathode, the amount obtained was 43.427 kg/batch from 100 kg of cathode waste raw material. Apart from that, data was obtained on the metals that were successfully recycled, namely NiO, MnO, CoO, Fe2O3, MgO, Al2O3, Cr2O3, and Li2O. The research results provide information that NMC battery waste can be an opportunity for the NMC metal supply chain and can reduce environmental pollution.

Abstract

The potential of oil palm empty fruit bunches (OPEFB) as a raw material for membrane production has not been fully explored. OPEFB waste contains a relatively high cellulose content, a natural polymer that can serve as a precursor for plastic and membrane synthesis. Membranes are semi-permeable barriers commonly employed in applications such as clean water purification and liquid waste treatment. To utilize cellulose from OPEFB, it must first be converted into cellulose acetate (CA) via an acetylation reaction. Cellulose acetate is a biodegradable polymer known for its hydrophilic nature, high chemical stability, and mechanical strength, making it a widely used material in membrane technology. Moreover, CA is suitable as a matrix for developing nanocomposite membranes with enhanced performance characteristics. Membranes are typically fabricated using the phase inversion technique, involving solvents such as acetone or dimethylformamide (DMF). The resulting membrane properties—including morphology, porosity, and chemical interactions—depend on the choice of polymer and additives in the casting solution. Additives such as nano-silica and polyethylene glycol (PEG) are often incorporated to improve tensile strength, increase hydrophilicity, and control pore size distribution. Optimizing the composition ratios of cellulose acetate, solvent, and additives is essential to achieve desirable properties, particularly for ultrafiltration (UF) applications. OPEFB offers promising potential as a sustainable, renewable resource for producing UF membranes, supporting circular economy principles and waste valorization in environmental applications.

Abstract

Plastic waste that has not been appropriately managed has caused concern for various stakeholders and has a negative impact on the environment. A way to minimize this issue is by promoting a circular economy through recycling. Despite this, many plastic wastes cannot be economically recycled; one of them is multilayer plastics due to the difficulty in sorting out the various types of materials contained in the layers. As an alternative, it may be possible to utilize multilayer plastic as a bitumen mixture; this method may avoid the separation process entirely. Bitumen is a component of asphalt, which is crucial to the construction of infrastructure. Plastics can potentially enhance the properties of modified bitumen, and they would assist in enhancing the quality of the asphalt. The aim of this study is to examine the impact of multilayer waste plastics on bitumen fabricated by the hot-mixing process. To enhance the compatibility between hydrophobic plastic and hydrophilic bitumen, lignin was used as a compatibilizer. The properties of bitumen with 3, 4, and 5 wt.% multilayer plastic and mixing times of 15, 30, and 45 minutes were evaluated. Accordingly, surface, chemical, thermal properties, and morphology were evaluated using sessile drop tests, Fourier Transform Infrared, thermogravimetry analysis, and scanning electron microscopy.
