Abstract

The high production of kepok banana is generating a significant amount of peel waste, contributing to environmental pollution. To address this issue, an innovative solution is the conversion of kepok banana peel into cellulose acetate as raw material for membrane production. Therefore, this research aimed to manufacture kepok banana peel cellulose acetate using varying concentrations of 1%, 1.5%, and 2% NaOH solvent, with acetylation times of 2 hours and 2.5 hours, respectively. The optimal results were achieved using 1% NaOH with kepok banana peel cellulose content of 56.07%. Furthermore, the best acetylation time occurred at a duration of 2.5 hours, producing a cellulose acetate content of 38.23% and a 2.3% degree of substitution (DS). These results suggested that the optimal combination for producing membrane from kepok banana peel is 1% concentration with an acetylation time of 2.5 hours, classifying it as cellulose diacetate.

Abstract

Household liquid waste, which is the residue from the activities of soapy water or bathing water, detergent water from washing clothes, faeces, washing water from cooking utensils containing oil in the settlement. This liquid waste problem needs to get serious attention, because it has complex characteristics and can disturb the health of the environment. One of the efforts to manage the environment is the processing of household wastewater through a series of physical and biological treatments, namely the aerobic biofilter process and using plant bioindicators, namely apu wood (Pistia stratiotes) which is able to absorb various heavy metals such as Fe, Zn, Cu, Cr, and Cd. Domestic wastewater used in this study was greywater, it was from kitchen activities. The purpose of this study was to determine the efficiency of reducing BOD, TSS, and fat oil in residual waste resulting from household activities by processing aerobic biofilter using bioball media and apu wood plants. The process of this research included the process of bacterial culture (seeding) for ± 2 (two) weeks and then proceeded by replacing new waste in the reactor for 5 (five) days at the biofilter reactor in which there was a bioball media and apu wood plants with downward and upward flow using a reactor made of glass with certain dimensions with a discharge of 0.35 ml/sec. The process results in a reduction efficiency of BOD of 70.51% from an initial BOD concentration of 300 mg/L to 88.49 mg/L. The efficiency of reducing TSS was 74.97% from the initial concentration of TSS 321 mg/L to 80.33 mg/L. In addition, the efficiency of reducing fat oil was 73.20% from the initial concentration of fatty oil 300.36 mg/L to 80.51 mg/L, so it can be explained that processing with bioball and apu wood plants can reduce the parameters of BOD, TSS, and fat oil, but the value was still above the standard quality of Minister of Environment Regulation No. 68/Menlhk/Setjen/Kum.1/8/2016.

Abstract

Increased population growth results in increasing human needs over time. Meeting the high needs triggered the development of industries that meet the needs. Problems arise from the many industries that emerge, one of which is an environmental problem. Many industries in Indonesia have not used good waste treatment standards, causing pollution from the rest of the production process in the industry, one of which contains heavy metals such as Pb, Zn, Mercury and so on. Heavy metal is a type of pollutant that is harmful to plants, animals and humans through the process of bioaccumulation in the food chain. The purpose of this research is the content of heavy metals that are harmful to the sustainability of ecosystems in the environment requires a long time so that one way to prevent heavy metal compounds that can be released to the environment is by managing the bioremediasi process with fragrant root medicinal plants (Vetiveria Zizanioides) which has hyperaccumulator properties which can absorb one of the heavy metals namely Cadmium (Cd) and Lead (Pb).

Abstract

Fertilizer is a nutrient that is the main need for plants. One of the organic materials that is widely used as organic fertilizer is chicken manure which can have an influence on the availability of nutrients and improve the structure of soil which is very deficient in organic nutrients and can also fertilize plants. One of the dry leaves that has the potential to be used as organic fertilizer is ketapang leaves, which have a C-Organic nutrient content of 60.32%; N-Total 0.55 % ; P-Total 0.14 % ; K-Total 0.20%. In addition, the nutrient content of chicken feces is N 1%; P 0.80% ; K 0.40% and water content 55%. The wood powder content consists of chemical components such as cellulose, hemicellulose, lignin and extractive substances. This research method uses a completely randomized design, consisting of 5 treatments of various raw material compositions of chicken manure, dry ketapang leaves and wood dust. The ratio of the use of organic fertilizer and soil is 50: 50. This research aims to determine the height growth and number of leaves for cayenne pepper based on from various raw material compositions of chicken manure, ketapang leaves and wood dust. This research consisted of 5 treatments of various raw material compositions of chicken manure, dry ketapang leaves and sawdust. The ratio of organic fertilizer and soil was 50: 50. The results from observing plant height were that P1 was 6 cm high and the highest number of leaves on P2 was 7 pieces. However, the addition of organic fertilizer with various compositions does not have much effect on the growth of cayenne pepper seeds.

Abstract

Sabut kelapa, salah satu komoditi di Cilacap, memiliki potensi besar sebagai bahan olahan untuk berbagai aplikasi termasuk sebagai pengisi komposit geopolimer. Namun, kandungan lignin yang tinggi pada serbuk sabut kelapa dapat menghambat pemanfaatannya secara optimal. Delignifikasi alkali merupakan metode yang digunakan untuk mengurangi lignin dan meningkatkan selulosa. Penelitian ini bertujuan untuk mengetahui pengaruh delignifikasi alkali terhadap perubahan struktur lignoselulosa serbuk sabut kelapa, sehingga hasil penelitian ini dapat dijadikan referensi pada optimalisasi sifat mekanik komposit geopolimer. Metode penelitian meliputi perlakuan delignifikasi alkali, dengan variasi konsentrasi 1% dan 2% larutan NaOH, pada serbuk sabut kelapa dan karakterisasi struktur lignoselulosa menggunakan Chesson-Datta dan FTIR (Fourier Transform Infra Red). Hasil penelitian menunjukkan bahwa perlakuan delignifikasi alkali berhasil menurunkan kadar lignin pada interval 9% - 11% dan mengubah struktur lignoselulosa serbuk sabut kelapa. Berdasarkan hasil FTIR, puncak serapan bilangan gelombang 3310,83 cm-1 membuktikan adanya gugus fungsi O-H stretch, pada bilangan gelombang 2917,56 cm-1 membuktikan adanya gugus fungsi C-H Stretch. Puncak bilangan gelombang 1370,68 cm-1 membuktikan adanya gugus fungsi C-H bend dan pada bilangan gelombang 1225,78 cm-1 membuktikan adanya gugus fungsi C-O stretch.
