Abstract

The purpose of the study is to determine the ability of the composting process composting time to examine the relationship to temperature, pH and levels of C, N, Ratio C / N, P using EM4 activator, MOD 71, sheep dungon cocoa waste biomass. The working principle of the study is to observe and analyze the decomposition ofbiomass wastes cocoa to different activators and observe the process of composting process variables for 7,14, 21, 28, 35, 42, 49, and 56 days with the analysis of temperature, pH and analyze levels of nitrogen (N),Carbon (C), Ratio C / N, and phosphorus (P). Results were obtained in accordance with the optimizationpoint of the graph N, C, Ratio C / N, and P. Then connected to the SNI table, suitable compost is compostactivator biomass using EM4, at 28 days with temperatures 54.88 0C and compost maturation is the 56dayof temperature 28 ° C with a pH of 7.46.Keywords: Biomass, activator, EM4, MOD 71

Abstract

It is necessary to design a nitrification bioreactor process so that further processing takes place optimally. Performance studies are carried out by evaluating the kinetic parameters that apply specifically to the applied process. The Monod model was applied to determine the value of kinetic parameters in designing and operating a bioreactor. This study aims to determine the value of the kinetic parameters to variations in feed concentration (50, 75, and 100%). The mechanism of the reactor process for the decomposition of pollutants, the influent is fed into the reactor with an up-flow pristaltic pump. The decomposition process provides contact time between organic matter and microorganisms, resulting in a good separation from the reactor outlet. The most optimum kinetic parameter value at 100% wastewater concentration with a value of (k) 1.1086 (dayˉ 1), (Ks) 1.0564 g l-1, (Y) 5.4862 mg MLVSS/mg, (kd) 1.7944 (dayˉ 1), (µm) 6.8372 (dayˉ 1).

Abstract

Kandungan senyawa kimia minyak jelantah memiliki sifat karsinogenik, terbentuk ketika proses penggorengan. Konsumsi minyak jelantah secara kontinu bisa mengganggu kesehatan. Namun apabila minyak jelantah dibuang begitu saja dapat mencemari lingkungan. Minyak jelantah bisa bermanfaat, salah satunya diolah menjadi produk sabun. Tujuan kegiatan pengabdian kepada masyarakat ini adalah untuk memberikan pelatihan dengan  mereduksi buangan limbah minyak jelantah ke lingkungan oleh masyarakat pesisir Desa Leppe sehingga resiko pencemaran air tanah bisa dikurangi. Metode yang digunakan yaitu sistem pengolahan limbah untuk mereduksi kedua limbah ini menjadi zero waste industry. Kegiatan ini dilaksanakan pada tanggal 15 November 2022. Sasaran kegiatan ini adalah 50 orang masyarakat Desa Leppe Kec. Soropia. Pengabdian masyarakat ini melalui 3 tahapan yaitu observasi, penyuluhan & pelatihan, serta pemantauan kegiatan evaluasi. Penyuluhan mengenai dampak pembuangan minyak jelantah ke lingkungan yang dilanjutkan dengan praktek membuat sabun dari limbah minyak jelantah serta sereh berbasis teknologi ramah lingkungan. Penyuluhan diawali dengan pemberian pre-test kepada subjek. Penyuluhan diakhiri dengan post-test untuk melihat kedalaman pemahaman subjek target. Indikator pemahaman dievaluasi dari instrumen angket sebelum serta setelah penyuluhan. Trampilnya peserta terlihat dari hasil desain kemasan produk sabun. Mitra yang terlibat pada aktivitas ini yaitu masyarakat pesisir Desa Leppe. Target dari aktivitas pengabdian masyarakat ini yaitu 50 orang masyarakat di Desa Leppe Kecamatan Soropia Kabupaten Konawe yang terdiri atas 6 RT dan 3 Dusun. Dapat disimpulkan bahwa kegiatan pengabdian ini berhasil, terlihat dari kehadiran masyarakat Desa Leppe, yang mengikuti kegiatan ini berjumlah 50 orang. Sehingga memenuhi sasaran total msyarakat yakni 100% dari yang ditargetkan, yakni: Dusun I (17 orang), Dusun II (17 orang), dan Dusun III (16 orang).The chemical compounds in used cooking oil have carcinogenic properties, which are formed during the frying process. Continuous consumption of used cooking oil can interfere with health. However, if used cooking oil is thrown away, it can pollute the environment. Used cooking oil can be helpful, one of which is processed into soap products. The purpose of this community service activity is to provide training by reducing the discharge of used cooking oil waste into the environment by the coastal community of Leppe Village so that the risk of groundwater pollution can be reduced. The method used is a waste treatment system to reduce these two wastes into a zero-waste industry. This activity was carried out on November 15, 2022. The target of this activity was 50 people from Leppe Village, Kec. Soropia. This community service goes through 3 stages: observation, counselling & training, and monitoring of evaluation activities. Counselling on the impact of disposal of used cooking oil into the environment, followed by making soap from waste using cooking oil and citronella based on environmentally friendly technology. Counselling begins with giving a pre-test to the subject. The counselling ended with a post-test to see the depth of understanding of the target subject. Understanding indicators were evaluated from the questionnaire instrument before and after counselling. The soap product packaging design results show the participants' skills. The partners involved in this activity are the coastal communities of Leppe Village. This community service activity targets 50 people in Leppe Village, Soropia District, Konawe Regency, which consists of 6 RTs and 3 Hamlets. It can be concluded that this service activity was successful, can be seen from the presence of the Leppe Village community, who participated in this activity totalling 50 people. To meet the total community target of 100% of the target, namely: Hamlet I (17 people), Hamlet II (17 people), and Hamlet III (16 people).

Abstract

Reprocessing organic vegetable waste from conventional markets can have beneficial effects, such as producing bioenergy, reducing the need for inorganic fertilizers, and minimizing the volume of contaminants in the environment. Organic material composting can help lower greenhouse gas emissions and generate income. Physical-chemical factors like temperature, pH, particle size, moisture content, aeration, and CN ratio were used to regulate the breakdown process. Trichoderma harzianum, an effective microorganism, and Trichoderma harzianum helped the degradation process function. High-quality compost is produced by converting organic matter in a bioreactor system, where the solid substrate replenishes nutrients. Based on the optimum point of the decomposition procedure, the analytical findings were achieved. After that the material had been homogenized and aerated, this process took place (oxygen). When the temperature is increased, the active and ripening stages take place, which triggers the breakdown process. The ideal temperature for composting, between 30-45 °C, was reached. The temperature steadily drops when the majority of the material has broken down, and the composting process is complete.
