Abstract

Biogas merupakan salah satu bentuk energi alternatif yang terbaharukan dan dapat diterapkan kepada masyarakat sebagai bentuk efisiensi penggunaan bahan bakar minyak ataupun gas dalam keperluan rumah tangga. Bahan bakunya diambil dari bahan yang mudah didapat dan sudah tidak dapat dipakai lagi, tetapi dapat di recycle menjadi biogas yang sangat bermanfaat bagi masyarakat. Dalam industri tempe yang berkembang di masyarakat terdapat limbah cair yang biasanya tidak dimanfaatkan dan dibuang begitu saja dilingkungan yang kemudian dapat mengakibatkan pencemaran terhadap lingkungan. Padahal sebagian besar kandungan dalam limbah cair tempe dapat dimanfaatkan menjadi biogas. Kelurahan Habaring Hurung, memiliki sebuah industry rumah tangga pembuatan tempe yang menghasilkan limbah cair dengan kuantitas yang cukup berlimpah, maka berpotensi sebagai penghasil biogas. Pelatihan pembuatan biogas di kelurahan Habaring Hurung, Kecamatan Bukit Batu, Kota Palangka Raya, ini bertujuan memberikan bekal kepada masyarakat, tentang pemanfaatan limbah cair tempe menjadi biogas. Tujuan dari pengabdian kepada masyarakat ini adalah memberikan gambaran berupa metode pembuatan biogas, bahannya yang berasal dari limbah cair tempe, sehingga dapat dimanfaatkan sebagai alternatif bahan bakar. Metode pelaksanaan terbagi dalam beberapa tahapan diantaranya persiapan yang meliputi menerbitkan surat tugas dan identifikasi masalah, wawancara yang meliputi survei kondisi lingkungan dan pemaparan rencana kepada mitra, perakitan reactor yang meliputi pengumpulan alat dan perakitan biogas digester, diakhiri dengan penyerahan biogas digester kepada pemilik industri tempe. Hasil yang dicapai dari kegiatan ini adalah warga masyarakat Kelurahan Habaring Hurung semakin memiliki wawasan yang terbuka untuk mengolah limbah cair tempe menjadi biogas, sehingga keberadaan limbah cair tempe yang awalnya mencemari lingkungan sekitar industri saat ini menjadi sebuah potensi energi terbaharukan yang mudah untuk dikembangkan.

Abstract

Antioksidan dapat didefinisikan sebagai kelompok senyawa kimia yang dapat melindungi sel-sel dalam tubuh dari kerusakan yang diakibatkan oleh radikal bebas. Penelitian ini bertujuan mengetahui efek antioksidan fraksi n-heksana daun jarak pagar. Rancangan yang digunakan dalam penelitian adalah quasi eksperimental dengan menggunakan seri konsentrasi (10; 20; 40; 80; 100; 160 μg/mL) fraksi n-heksana dan kontrol positif (vitamin C) sebagai penghambat DPPH sebagai radikal bebas dan tiap-tiap konsentrasi dilakukan dengan tiga kali pengulangan. Penelitian dikerjakan di Laboratorium Kimia FMIPA Universitas Palangka Raya dan Laboratorium Fakultas Ilmu Kesehatan universitas Muhamadiyah Palangka Raya. Ekstrak etanol (200 gram) yang dihasilkan selanjutnya dipartisi dengan n-heksana:air (3:1) menggunakan corong pisah sehingga dihasilkan fraksi n-heksana sebesar 25,5 gram. Kemudian pengujian aktivitas antioksidan menggunakan metode DPPH (2,2-diphenyl-1-picrylhidrazil). Data yang dihasilkan kemudian dilakukan uji statistik anova satu arah, kemudian analisis lanjutan menggunakan post hoc Tamhane pada CI 95%. Hasil penelitian menunjukkan aktivitas antioksidan fraksi n-heksana daun jarak pagar (Jatropha curcas) dan kontrol positif (vitamin C) dengan nilai inhibitory concentration (IC50) berturut-turut sebesar 77,78±0,12(μg/mL) dan 8,78±0,21 (μg/mL). Berdasarkan uji anova satu arah, terdapat perbedaan yang bermakna pada masing-masing konsentrasi terhadap persen penangkapan radikal bebas (pvalue<0,05). Konsentrasi 160 μg/mL adalah konsentrasi terefektif dalam penangkapan radikal bebas. Inhibitory concentration (IC50) fraksi n-heksana daun J. curcas termasuk aktivitas antioksidan dengan kategori kuat.

Abstract

The level of understanding among tempeh producers in Habaring Hurung Village on waste treatment remains significantly limited. Liquid waste from production is directly discharged into water bodies and causes various environmental problems. Consequently, a program was implemented to provide knowledge regarding suitable technology for effectively managing tempeh liquid waste to produce environmentally sustainable biogas. This initiative occurred in Habaring Hurung Village in the Bukit Batu District of Palangka Raya City. The community empowerment activity begins with a careful preparation process, followed by collaborative efforts with partners, the assembly of biogas reactors, and socialization initiatives, and concludes with an evaluation phase. The findings derived from this project indicate that the Habaring Hurung Village community has demonstrated proficiency in constructing biogas reactors. Moreover, there has been an obvious improvement in the community's understanding of liquid waste utilization and environmental management.

Abstract

The skin is the largest organ on the human body that plays a vital role in protecting the body from environmental aggressions and maintaining internal balance, however, the natural aging process and exposure to external factors can cause various skin problems, including loss of elasticity, fine lines, and hyperpigmentation. To address these issues, the development of skincare products such as anti-aging gels is important. The aim of this study was to optimise the base of the anti-aging gel formulation by considering the selection of gelling agents with appropriate variations.The research method was conducted by obtaining five different formulas using a combination of gelling agents Carbopol and CMC Na with variations of Formula 1 which is 1% b/v carbopol with 2% b/v CMC Na, Formula 2 which is 1.25% b/v carbopol with 1.75% b/v CMC Na, Formula 3 which is 1.5% b/v carbopol with 1.5% b/v CMC Na, Formula 4 which is 1.75% b/v carbopol with 1.25% b/v CMC Na and Formula 5 which is 2% b/v carbopol with 1% b/v CMC Na . Physical testing was conducted to evaluate the formulation characteristics, including colourimetry, pH, viscosity, adhesion, and spreadability, comparisons between different formulas were conducted to determine the best base formula. The results showed that formula 5 with the ratio of gelling agent carbomer 2% b/v and CMC Na 1% b/v, is the optimal formula supported by physical testing, namely the metric choleretic test is good, homogeneous, pH 6.237 in accordance with the pH range of the skin, the Viscosity test has the highest viscosity of 148.34 d.Pas, the longest adhesion test with an adhesion time of 9.535 seconds, allowing the active substance to more easily penetrate the skin and be absorbed.

Abstract

Dragon scale (Drymoglossum piloselloides) leaf is a plant that contains secondary metabolites with antioxidant potential. This plant is known for its easy to grow nature and has a wide habitat distribution. The extraction method using acetone solvent has been proven effective in extracting secondary metabolites from this plant. To improve the extraction efficiency, this study used an optimization approach using the Central Composite Design (CCD) method. CCD involves three main factors in extraction experiments, namely solvent concentration, extraction time, and extraction temperature. Experiments were conducted with variations of these factors to find the optimal extraction conditions. The results of CCD method showed that the solvent concentration of 70%, extraction temperature at 52°C, and extraction time of 60 minutes. Statistical analysis showed that the model used was significant, with an F-value of 9.20 and a P-value less than 0.01159, indicating that the factors tested had a significant effect on the extraction results. The results of this study have great potential in maximizing the use of dragon scale leaves as a source of antioxidant secondary metabolites.

Abstract

Water is a vital necessity for human and living things in general. It is undeniable that the decline in water quality today is the result of human activities that overexploit the environment. People's lifestyles that pay less attention to environmental aspects such as throwing garbage out of place, disposing of hazardous waste, and changing the function of forest areas that can increase the potential for erosion and often cause sedimentation at the bottom of the waters have a negative impact both directly and indirectly on the natural environment, especially water sources. High rate of forest degradation and deforestation has a significant impact on changes and decreases in water quality. In this study, water quality monitoring was conducted using several parameters as an initial step to understand the condition at the Dam and Clean Water Facility in Banturung Village, Bukit Batu District, Palangka Raya City. The results obtained from the analyzed parameters include odorless, pH 5.9, turbidity 1.0 NTU, temperature 28.1 °C, color 3.63 TCU, total dissolved solids (TDS) 10.2 mg/L, nitrate (NO3-) 0.608 mg/L, nitrite (NO2-) 0.002 mg/L, iron (Fe) 0.038 mg/L, and manganese (Mn) 0.006 mg/L.
