Abstract

Abstrak Lumpur minyak bumi (oil sludge) memiliki kandungan kontaminan petroleum hidrokarbon terbesar, karenanya pengolahan limbah oil sludge perlu dilakukan agar tidak mencemari lingkungan. Penelitian yang menguji kemampuan jamur indigenus Riau (Penicillium sp. PN6) dan legum akuatik (Neptunia oleracea) dalam meremediasi senyawa hidrokarbon dengan pengukuran total petroleum hidrokarbon (TPH) pada limbah oil sludge telah dilakukan. Pertumbuhan N. oleracea dilakukan pada media limbah oil sludge dengan konsentrasi 25, 50, 75, dan 100%. Selanjutnya dilakukan pemberian inokulum Penicillium sp. PN6 ke dalam media pertumbuhan. Hasil penelitian menunjukkan bahwa persentase pertumbuhan N. oleracea adalah 95,58; 85,87; 25,55; dan 0%, berturut-turut pada limbah oil sludge 25, 50, 75, dan 100%. Terjadi penurunan konsentrasi TPH awal pada semua perlakuan di akhir pengamatan. Penicillium sp. PN6 meningkatkan degradasi TPH dari limbah oil sludge dibandingkan dengan kombinasi Penicillium sp. PN6 dengan N. oleracea, tetapi kombinasi Penicillium sp.PN6 dengan N. oleracea meningkatkan persentase penurunan TPH dari limbah oil sludge dibandingkan dengan menggunakan Penicillium sp. PN6 saja. Penicillium sp. PN6 dan kombinasinya dengan N. oleracea sama-sama mampu menurunkan pH limbah oil sludge.Abstract Oil sludge contains the largest contaminant of petroleum hydrocarbon that needs treatment to prevent its pollution into the environment. A study examining the ability of a Riau indigenous fungi (Penicillium sp. PN6) and an aquatic legume (Neptunia oleracea) to remediate hydrocarbon compounds by determining total petroleum hydrocarbon (TPH) in oil sludge waste has been conducted. The growth of N. oleracea was performed in the oil sludge waste media by concentrations of 25, 50, 75, and 100%. The medium was inoculated with Penicillium sp. PN6. The results showed that the percentage of growth of N. oleracea were 95.58; 85.87; 25.55; and 0%, in the oil sludge waste of 25, 50, 75, and 100%, respectively. There was a decrease in initial TPH concentration at all treatments at the end of the observation. Penicillium sp. PN6 increased more TPH degradation of the oil sludge waste compared to a combination of Penicillium sp. PN6 and N.oleracea, but the combination increased the decrease percentage of TPH compared to those that used Penicillium sp. PN6 only. Penicillium sp. PN6 and its combination with N. oleracea are both able to decrease pH of the oil sludge waste. Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v11i1. 6350

Abstract

Noodles are a processed food product favored by most Indonesians, generally made from wheat which must be imported. Kepulauan Meranti Regency is the largest producer of sago in Indonesia. One of the products made from sago that is widely produced in Meranti is sa.go noodle. Making noodles with local raw materials such as sago and sweet potato is an effort to improve food security. Traditional sago noodle has high carbohydrate and fiber content but still has disadvantages such as not having inulin content as a prebiotic, less antioxidant and a less attractive color, while purple sweet potato contains inulin as prebiotic components, high antioxidants, vitamins and minerals.The utilization of prebiotics insago noodle has multiple advantages since they improved probiotic growth in the body, sensory features and provide a more well-balanced nutritional composition as functional food. This community service program aims to training on the process of making prebiotic sago noodles to the community in Alai Selatan Village.This activities are carried out by course and practice methods.The results showed that the participants were interested in making prebiotic sago noodles because they had a more attractive features, more nutritious and had a delicious taste. Prebiotic sago noodles can be used as an effort to biodiversify sago noodle products to support food security and improve the community's economy.

Abstract

Used oil waste is often dumped on the ground around the workshop, causing soil pollution which can reduce the function of the soil. The most difficult contaminants in used oil waste to decompose are hydrocarbon compounds, which are highly toxic, polycyclic aromatic hydrocarbons (PAHs). The concentration of oil hydrocarbon contaminants in a sample is determined by measuring the total petroleum hydrocarbon (TPH) concentration. This study was conducted to determine the germination ability of Helianthus anuus, Less seeds on soil media contaminated with waste oil at different concentrations of Total Petroleum Hydrocarbon (TPH). The results showed that the concentration of TPH in the media could inhibit the speed of seed germination. Treatment with low concentration of TPH 2.7% in the media increased % germination, shoot and root length and sprout biomass compared to the medium/intermediate (8.00%) and high (12.26%) TPH treatments and controls. However, there was no significant difference between all treatments regarding germination time and shoot length, although in the low TPH treatment (2.70%) there was a tendency for germination time to be faster than the other treatments, as well as to shoot length which was longer than the other treatments. The higher TPH concentration in the media can inhibit germination time, germination percentage, shoot and root length and biomass. Morphological observations of the growth of sprouts showed an inhibition of root hair formation along with the high TPH content in the media, but all treatments did not affect the growth of the shoots.

Abstract

Flood plain river is one of the characteristics of Riau Province. The difference between H. heterorhynchus fish and other species is its distinctive mouth and bent body. H. heterorhynchus is a fish with high economic value. These fish are often overfished, which can lead to a decline in the fish population in the future. Therefore, this research was carried out to be able to see the growth pattern, sex ratio and distribution of fish so that it can become the basis for information, cultivation and preservation of H. heterorhynchus. The number caught was 78 (56.67%) male fish and 36 (43.33%) female fish. The total body length of male fish is 19-41 and female fish is 19-50 cm, the total body weight of male fish is 40-310 g and female fish is 40-600 g. The allometric growth pattern of male and female fish was negative, with b values ​​of 2.8 (males) and 2.2 (females). Correlation analysis of H. heterorhynchus fish are r= 0.98 (male) and r=0.877 (female). The sex ratio of male and female fish is 1.16:1. Male fish are 19-22 cm and 23-26 cm (small fish), 27-30 cm and 31-34 cm (medium fish), and 35-38 cm and 39-42 cm (large fish). Female fish are 19-24 cm and 25-30 cm (small fish, 31-36 cm and 37-42 cm (medium fish), 43-48 cm and 49-54 cm (large fish).
