Abstract

Clear glass waste, a prevalent inorganic waste in Indonesia, presents an opportunity for eco-friendly adsorbent development. This study explored the impact of varying NaOH concentrations (1M-4M) on the Pb2+ ion adsorption capacity of silica gel synthesized from clear glass waste via the sol-gel method.While conclusive determination of the optimal NaOH concentration for Pb2+ adsorption remained outside the study's scope, valuable insights were obtained. FTIR analysis confirmed the presence of silanol (SiOH) and siloxane (Si-O-Si) groups within the silica gel structure, with the SiOH group specifically identified at a wavenumber of 957 cm?¹. Increasing NaOH concentration from 0.5 M to 4 M significantly enhanced the formation of silanol groups on the silica gel surface, as evidenced by the increasing area of the corresponding peak in the FTIR spectrum (3.2 to 71.0 arbitrary units). This positive influence translated to an improved Pb2+ adsorption capacity, with the highest performance of 2.3 mg/g achieved at the highest NaOH concentration. However, the relationship wasn't perfectly linear, suggesting the influence of additional factors like silanol distribution and the presence of competing ions. This work demonstrates the potential of waste glass-derived silica gel for Pb2+ remediation while emphasizing the need for further research to optimize synthesis parameters and elucidate the full adsorption mechanisms.

Abstract

Industri tekstil di Indonesia mengalami perkembangan yang sangat pesat, setiap produksinya akan menghasilkan limbah berupa limbah pewarna. Methilene Blue adalah limbah pewarna yang paling banyak diproduksi. Limbah Methylene Blue ini nantinya akan masuk ke lingkungan perairan yang dapat berdampak negatif bagi kesehatan manusia. Kadar yang diizinkan dalam perairan berkisar antara 5-10 mg / L. Tujuan dari penelitian ini untuk mengurangi kandungan zat warna Mehylene Blue di perairan dengan proses adsorpsi menggunakan adsorben biji lengkeng yang diaktifkan dengan HNO3 O,O1M dengan metode batch. Instrumen yang digunakan adalah FTIR dan UV-Vis. Penelitian ini dilakukan untuk mendapatkan kondisi optimum dengan melihat kapasitas serapan zat warna berupa variasi waktu kontak dan kecepatan pengadukan. Waktu kontak optimum diperoleh 150 menit dengan kecepatan pengadukan 200 rpm sehingga diperoleh daya serap 63,65 mg/g dengan persentase absorpsi 93,78%.

Abstract

Bunkate Village, Jonggat District, Central Lombok Regency, has fisheries potential, especially freshwater fish farming, but this potential has not been optimally managed. KKN-PMD students from Mataram University initiated technical guidance and processing and marketing activities for freshwater fish farming products. This activity includes training in making fish sticks as one of the product form diversifications and education on effective food product marketing strategies. The program implementation method includes observation, interviews with fish farmers, recipe formulation, and implementation of technical guidance attended by the surrounding community, especially PKK mothers. The results of the activity showed that participants were enthusiastic in participating in the training and gained new skills in processing tilapia into products with higher selling value in the form of fish sticks and marketing strategies for fishery products, which are expected to increase the income and welfare of the village community. Through this activity, it is hoped that the Bunkate Village community will be able to develop fisheries-based businesses independently and sustainably, thereby increasing the welfare of the village community, especially freshwater fish farmers.

Abstract

Bunkate Village, Jonggat District, Central Lombok Regency, has abundant freshwater fisheries potential, especially in freshwater fisheries cultivation. However, this potential has not been managed optimally. Through a community empowerment approach, workshop activities are focused on improving the skills of village communities in processing fisheries cultivation products, as well as more effective fisheries product marketing strategies. Therefore, KKN PMD students from Mataram University initiated the Freshwater Fisheries Cultivation Results Processing and Marketing Workshop program as a solution to increase the added value of fisheries products. This activity includes training in making fish sticks as a form of product diversification and education on effective marketing strategies. The program implementation method involves observation, interviews with fish farmers, recipe formulation, and implementation of workshops attended by the local community, especially PKK mothers. The results of the activity showed that participants were enthusiastic about participating in the training and gaining new skills in processing tilapia into products with higher selling value and marketing fisheries products, which are expected to increase the income and welfare of the village community. Through this activity, it is hoped that the Bunkate Village community will be able to develop fisheries-based businesses independently and sustainably, thereby increasing the economic welfare of the village.

Abstract

Makanan halal menjadi perhatian khusus karena selain sebagai kebutuhan sehari-hari, makanan halal juga menjamin kebaikan, kebersihan dan manfaatnya bagi tubuh. Keterjaminan halal dari suatu produk makanan memerlukan sertifikasi dari lembaga yang berwenang. Saat ini pemerintah Negara Indonesia mencanangkan program sertifikasi halal bagi produk makan dan minuman melalui program sertifikasi halal gratis (SEHATI) melalui skema self-declare. Program ini memiliki 1 Juta kuota sertifikat halal dan membutuhkan pendamping proses produk halal (PPH) dalam pengajuannya. Akan tetapi pemerataan dan ketersebaran informasi terhadap program SEHATI belum maksimal dikarenakan terbatas nya media dan sumber daya manusia. Oleh karena itu tim pengabdian kepada masyarakat dan Lembaga Pendamping Proses Produk Halal (LP3H) Universitas Negeri Padang melaksanakan sosialisasi, edukasi dan pendampingan terhadap pelaku usaha di negeri Sikucua Utara, Kabupaten Padang Pariaman. Setelah dilaksanakannya edukasi, perlu dilakukan analisa terhadap minat pelaku usaha dalam mengurus sertifikat halal dalam program SEHATI. Variabel minat dievaluasi dari lima aspek yang terdiri dari perhatian, ketertarikan, keinginan, keyakinan, dan tindakan. Data dikumpulkan menggunakan kuesioner dengan responden yang berjumlah 21 orang. Dari data yang diperoleh diketahui bahwa pelaku usaha memiliki tingkat minat yang sangat tinggi pada semua aspek yang dievaluasi.
