Abstract

Jenis dan variasi sampah dapat menunjukkan jumlah dan tingkat perekonomian penghuninya. Tingginya timbulan dan variasi sampah sering menjadi masalah pada beberapa perumahan. Kondisi rumah yang berdekatan, lahan kosong yang sedikit, kondisi TPS yang terbuka serta pengelolaan sampah yang kurang menjadi permasalahan bagi penghuni yang tinggal di perumahan tersebut. Kondisi ini dapat menjadi penyebab munculnya penyakit, bau busuk, serta lingkungan yang tidak sedap dipandang. Berdasarkan hal tersebut, maka perlu dilakukan kegiatan penyuluhan. Kegiatan penyuluhan ini bermaksud untuk memberikan informasi tentang sampah hasil rumah tangga, jenis pengelolaan yang sesuai, serta hasil pengelolaan jika sampah tersebut dapat diolah dan menjadi income. Teknik yang digunakan pada kegiatan pengabdian ini adalah pendekatan persuasif dalam pemilahan, pewadahan, dan pengumpulan sampah dari sumbernya. Fokus kegiatan pengabdian ini dilaksanakan di Perumahan Griya Rumaisha yang melibatkan ibu-ibu perumahan tersebut. Diharapkan dengan adanya kegiatan ini dapat meningkatkan pengetahuan ibu-ibu mengenai pengelolaan sampah yang dibuktikan dengan adanya perubahan di lingkungan perumahan Griya Rumaisha. Hasil pengelolaan ini juga nantinya dimanfaatkan sebagai pendapatan baru di pemukiman tersebut dengan membuat cairan eco enzyme

Abstract

Peat water is raw water which is used as a source of clean water by the people of Pekanbaru. However, after testing according to the Regulation of the Minister of Health of the Republic of Indonesia for clean water standards No. 416/MENKES/PER/IX/1990 the results of measuring the color and turbidity value of peat water are above the quality standards, namely 219 TCU and 15.1 NTU. This value is very far from the color and turbidity quality standards with respective concentrations of 15 TCU and 5 NTU. Therefore, in this research, an adsorption process was carried out using an adsorbent from Patin bone waste (Pangasius sp.) typical of Riau province by utilizing a physical activation process to open pores and help facilitate absorption. The variable used in this research were adsorbent mass and stirring speed. For adsorbent mass there was a variation of 0.1; 0.3; 0.5; and 0.7 grams while the stirring speed was 50, 100, and 150 rpm with a stirring time of 120 minutes and each sample had a particle size of 100 mesh. The results of this adsorption process obtain the best efficiency value at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm. The color reduction efficiency reached 96.35%, namely 8 TCU, while the turbidity reduction efficiency at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm reached 92.72%, namely 1.1 NTU.

Abstract

The availability of oil palm empty fruit bunches in Indonesia could be an important source of biomass to be utilized as a solid fuel feedstock. In this work, the thermal behavior and degradation of oil palm emty fruit bunches was investigated with a thermogravimetric analyzer in nitrogen atmosphere. The samples were heated from room temperature to 900 oC at heating rates of 20 oC min-1. The ultimate and proximate analysis revealed that oil palm empty fruit bunches contains high volatile matter, fixed carbon and ash content while the caliric value was 17.87 MJ/kg. Thermogravic analysis results indicated thermal degradation of samples occurs in three stages, namely drying and evaporation, active degradation and passive degradation. In addition, active degradation commenced at 148 oC with a peak of degradation temperature of 322.5 oC resulting in 68.32% weight loss.

Abstract

Supercapacitors are increasingly developing energy storage devices because they have advantages over conventional batteries and capacitors, such as high power density and long cycle life. Electrolytes are solutions that contain ions and function as electrically conductive media. In chemistry, electrolytes usually consist of acid, base, or salt solutions. The electrolyte used in supercapacitors plays a crucial role in achieving the desired power and energy density. In general, electrolytes are divided into two types based on their phase form, namely liquid and solid or gel electrolytes. Liquid electrolytes can be acids, bases or salts. While gel electrolytes are electrolytes that are denser in nature so that they can reduce leakage.

Abstract

Empty Fruit Bunches (EFB) of oil palm are the main solid waste generated by the palm oil industry, with an increasing volume and high lignocellulosic content that can affect the decomposition process. This article aims to review the effectiveness of various microorganisms as bioactivators in EFB composting based on experimental studies and recent literature. The review results indicate that using microbial consortia such as Trichoderma spp., cellulolytic bacteria, and local microorganisms (MOL) is more effective than single microorganisms in reducing the C/N ratio to levels approaching the compost quality standard (<20). Aerobic composting methods with proper aeration management and the addition of organic materials can also accelerate decomposition. Further research is recommended to examine the interactions among microorganisms within the consortia and to conduct application trials to validate the agronomic benefits of EFB compost sustainably.

Abstract

Penghijauan adalah sebuah kegiatan yang penting untuk dilakukan dalam menangani permasalahan lingkungan. Desa Sidomulyo, Kec. Lirik, Kab. Indragiri Hulu merupakan salah satu desa yang dikelilingin perusahaan – perusahaan besar sehingga menyebabkan desa ini menjadi gersang, tandus, udara panas Upaya penghijauan merupakan sebuah salah satu upaya dalam mengatasi suatu masalah lingkungan yang terjadi di sebuah daerah.Untuk fasilitas penghijauan di desa ini cukup memadai tetapi masyarakat yang masih kurang mengoptimalkan lahan yang ada untuk melakukan penghijauan. Melalui keterangan dari kepala desa setempat dari hasil survey yang telah dilakukan bahwa masyarakat desa sidomulyo masih minim kepedulian terhadap kebersihan lingkungan dengan terbuktinya masih banyak masyarakat yang membuang sampah sembarangan seperti di lahan kosong dan dikebun sawit. Maka dari itu diperlukannya kesadaran bagi masyarakat untuk lebih memperhatikan lingkungan desa tersebut dengan melakukan membuat tong sampah dan pemanfaatan tanaman toga / tanaman obat keluarga yang merupakan hasil budidaya rumahan yang memiliki khasiat sebagai obat.
