PEAT WATER TREATMENT INTO CLEAN WATER USING COMPOSITE CERAMIC MEMBRANE NANOFILTRATION TECHNOLOGY

The provision of clean water is an urgent need that must be realized in order to solve the problems that continue to be faced by people living on peatlands. The purpose of this research is to process peat water into clean water using nanofiltration method by ceramic membrane based on clay, activated carbon nanoparticles of Oil Palm Empty Fruits Bunch (OPEFB) as an additive and iron powder as a reinforcement. Peat water is first neutralized by addition of quicklime then processed through various microfiltration methods with sponges with pore sizes, namely 0.5 µm, 0.3 µm 0.1 µm and activated carbon and finally processed through ceramic membranes made from OPEB activated carbon nanoparticle additives. The pressure is set at 1 bar, 1.5 bar and 2 bar. The raw material for peat water from the Telang River is acidic with a pH value of 4.1 and contains TSS 147.5 mg/L, Fe 0.33 mg/L, Mn 0.56 mg/L, Zn 0.02 mg/L, NH3- N 0.58 mg/L, NO2-0.19 mg/L, PO4-3 0.264 mg/L, and BOD5 12.1 mg/L. It was found that, the greater the transmembrane pressure difference and the longer the operating time used, the better the permeate yield. The difference in pressure of 2 bar gives the best results in reducing the levels of contaminants contained in peat water with an average percent rejection reduction of TSS 91.89%, Fe 70%, Mn 93.2%, Zn 95%, NH3-N 68, 6%, NO2- 70%, PO4-3 38.14%, and BOD5 91.99%

Pelatihan Sistem Informasi Pemesanan dan Alat Fb-Hecool Pada Umkm Zona Kopi di Kabupaten Tanah Laut

Adanya wabah Corona Virus Disease (Covid-19) yang menyebar di Indonesia sejak Maret 2020 memberikan dampak penurunan omzet pada Usaha Mikro, Kecil, dan Menengah di seluruh Indonesia, termasuk Zona Kopi yang berada di Kecamatan Pelaihari, Kabupaten Tanah Laut. Zona Kopi yang relatif dekat dari Politeknik Negeri Tanah Laut, yakni 6,7 km membuat tim pengabdian berinisiatif untuk menjadikan Zona Kopi sebagai mitra pengabdian dalam rangka membantu untuk mengatasi permasalahan yang terjadi akibat Covid-19. Tim pengabdian yang merupakan gabungan dari dosen Program Studi Teknologi Informasi dan Program Studi Teknologi Otomotif Politeknik Negeri Tanah Laut mengusulkan pembuatan sistem informasi pemesanan berbasis web dan alat FB-HECOOL yang dapat membantu mempertahankan suhu makanan dan minuman ketika dalam proses pengantaran. Setelah tim menyelesaikan pembuatan sistem informasi pemesanan dan alat FB-HECOOL, tim pengabdian melakukan kegiatan pelatihan tata cara penggunaannya kepada pemilik dan karyawan Zona Kopi sehingga peserta dapat mempunyai kemampuan untuk mengoperasikannya. Sistem informasi pemesanan dan alat FB-HECOOL ini selanjutnya dihibahkan kepada Zona Kopi. Hasil dari kegiatan pengabdian ini semua peserta dapat menggunakan sistem informasi pemesanan dan alat FB-HECOOL sehingga sistem dan alat yang dihibahkan dapat digunakan secara optimal

I am mismatched, I am doing well: horizontal job-education mismatches and workers’ Well-being

Objectives: This study examines whether psychological empowerment plays a role in job crafting and employee well-being for workers who face horizontal educational mismatches. A horizontal educational mismatch could be defined as a mismatch between the field of education and current occupation. This study shows that horizontal educational mismatches which are increasingly commonplace in society, especially in Indonesia, may affect the well-being of workers. Employee well-being describes the overall well-being of employees, such as physical, psychological, and individual aspects. Methods: The study’s respondents are 361 Indonesian workers with horizontal educational mismatches. The study’s tools are employee well-being scale (EWBS), job crafting questionnaire (JCQ), and psychological empowerment questionnaire (PEQ). The measuring tools were adapted into the Indonesian language, and data was analyzed by Andrew F. Hayes’s simple regression mediation model no.4 PROCESS v4.0. Results: The study reveals that psychological empowerment facilitates job crafting and employee well-being for workers with horizontal educational mismatches. It also shows that employees who are psychologically empowered are those who are supported in taking responsibility for enhancing their performance and their contribution to the organization. As a result of the increased demand for productivity, employees must enhance their skills and knowledge to achieve higher job demands instead of simply establishing opportunities for wellbeing and self-development. That is, workers are given the abilities and resources required to compensate for the shortages caused by the horizontal educational mismatch they face. Conclusions: This study fills in a research gap by shedding light on the indirect effect a horizontal educational mismatch might have on workers’ competence and will-being

Kurnia's Web-Based Drill Method Can Measure the Level of Toothbrushing Skills of Blind Children

Background: Blind children have limited vision so that the health of the oral cavity is lower than that of children with normal vision. To improve the dental and oral health of blind children, a change in skills is needed. Choosing the right method of delivering educational material is very helpful in changing target skills. Kurnia's Web-based Drill method with audio modification can be an innovation in providing dental and oral health education. Where audio media that relies on sound can help optimize the sense of hearing that is still functioning so that the message conveyed can be easily remembered and understood by blind children.Research Objective: Build a web-based model of Kurnia's Drill method to improve toothbrushing skills in blind children.Methods: Research and Development (RD) and model testing (Quasi-Experimental Control Group Pretest and Posttest Design studies). The research subjects of blind children were divided into 2 groups, namely intervention and control. The results of the model design are validated by experts. The data were tested using intraclass, paired t-test and independent t-test correlation coefficients.Results: Kurnia's Drill web-based method is feasible as an educational model for dental health maintenance in blind children (p= 0.000). The implementation of this model effectively improved the brushing skills of blind children (p= 0.047) and decreased the debris index of blind children (p= 0.000) compared to the control group.Conclusion: Kurnia's Drill web-based method effectively improves brushing skills and decreases debris index in visually impaired children.
