Indonesia has various types of vegetation which are used as natural coagulants or biocoagulants. Coagulants can be divided into chemical coagulants and natural coagulants (biocoagulants). Biocoagulants are more environmentally friendly and can be obtained from natural ingredients, both animals and plants, one of which is Moringa seeds. Moringa seeds or with the Latin name Moringa oleifera are a type of plant from the Moringaceae family. From several previous studies, Moringa seeds were used as a more economical and environmentally friendly wastewater treatment method. Moringa seed biocoagulant in powder form is made from ripe and old moringa seeds and contains less than 10% water. Moringa seed biocoagulant contains 4αL-rhamnosyloxy-benzylisothiocyanate and is a determinant of coagulation effectiveness. This active substance is able to absorb pollutants in waste water. This research aims to treat tofu waste with moringa seed biocoagulant in reducing pollutant parameters, namely TSS (Total Suspended Solid) and COD (Chemical Oxygen Demand). Results of the removal of pollutants from moringa seed powder biocoagulant in tofu waste water the efficiency value obtained for each TSS parameter, and the COD for the TSS parameter is 54.4%. and for the COD parameter of 14.6%, it can be concluded that the efficiency value for each parameter still does not meet the effectiveness value.

Plate and Frame Heat Exchanger (PFHE) is a plate and frame type heat exchanger that is efficient and effective in improving energy efficiency. Research using PFHE aims to determine the effect of increasing the flow rate of hot fluid on heat exchanger performance. This research was conducted at a flow rate variation of 0.7 L/min, 0.9 L/min, 1.1 L/min, 1.3 L/min, 1.5 L/min, 1.7 L/min, and 1.8 L/min with 180 seconds of testing each variation and recording data every 2 seconds. The cold fluid used is tap water and the hot fluid used is distilled water. The results showed that with the increase in hot fluid flow rate, the performance of PFHE also increased because the effectiveness of NTU (Ɛ-NTU) increased. The Ɛ-NTU value of unidirectional flow is 25.37% - 44.87% and in the opposite direction 37% - 68.39%. The largest Ɛ-NTU value in the countercurrent flow indicates that the countercurrent flow is more effective than the unidirectional flow. In addition, increasing the flow rate increases the Reynold's number (Nre) and Nusselt's number (Nu) which indicates the greatest convection heat transfer occurs at the highest flow rate.

Human dependence on mineral-based energy sources poses challenges related to toxicity, depletion, degradation, and environmental hazards. An appropriate replacement for mineral-based lubricants has yet to be realized; one available option for humans is alternative, renewable, environmentally friendly, and biodegradable energy sources. Lubricants play an important role in product processing, transportation, agriculture, and other key sectors in industrial development. This study was conducted to explore the potential use of palm oil as the main ingredient with the addition of rubber as an additive. The method of making the lubricant involved mixing 3%, 5%, and 7% rubber latex with sonicated palm oil using UAE. Next, wear testing was performed using a tribometer based on the ball-on-disc principle, utilizing a modified bench-top drill machine. The testing was carried out at room temperature, maintaining a constant load of 8.83 N and a rotational speed of 180 rpm for 5 minutes per sample. Microscopic analysis of the wear scars on the plate samples showed different wear patterns and characteristics for each lubricant, with measurements taken at various positions for accuracy. The results indicated that the lubricant with a 5% rubber mixture was the best, with a wear width of 535.9126 µm, compared to the commercial lubricant (SAE 15W 40) which had a wear width of 539.906 µm. This research demonstrates the potential use of a palm oil and rubber mixture as a more environmentally friendly lubricant alternative.

Laboratory is one of the generators of hazardous liquid waste derived from chemicals used in practice and research. The waste is very dangerous when discharged into the environment because of the pollutants it contains. Therefore, it is necessary to treat the waste before it is disposed of to minimize the impact of pollution caused by the waste. The study aims to compare the effectiveness of zeolite adsorbents and activated carbon in reducing COD, TSS, and Cr heavy metals. Waste treatment is carried out by coagulation and adsorption methods. The adsorption process is performed using two types of adsorbents: zeolite and activated carbon. This study was carried out by variing the mass of the adsorbents at the time of complaining for 120 minutes in batches. Variations in the masses of the used 3, 5, 7, and 10 grams of adsorbenes. The results of the study showed that the more adsorbanes used, the higher the reduction of pollutant levels. The use of 10 grams of activated carbon adsorbents can reduce TSS pollutants levels of 92%, COD 95%, Cr 65%, and pH 5,0-6,38.

Liquid waste from the tofu industry contains various organic and inorganic substances which can reduce water quality. This research aims to assess the effectiveness of Poly Aluminum Chloride (PAC) as a coagulant in reducing pollution parameters in liquid waste from the tofu industry. In this study, experiments were carried out with three variations of PAC doses (75 mg/L, 150 mg/L, and 225 mg/L) and different stirring times (10, 15, and 20 minutes) using the jar test method. The jar test method is a standard laboratory technique used to determine the optimal dose of coagulant needed to remove turbidity from wastewater. The results show that a PAC dose of 225 mg/L with a stirring time of 20 minutes is the optimal condition, reducing Total Dissolved Solids (TDS) from 996 ppm to significantly lower. The initial conductivity of 1971 µs decreased after the addition of high doses of PAC and longer stirring times. The pH parameter increased from 4 to 5. Although still acidic, this increase indicates a reduction in acidity, which can be useful in reducing negative impacts on the aquatic environment. The color of the wastewater becomes clearer and the odor decreases, indicating a decrease in organic compounds and dissolved substances. The temperature remained stable at 28ºC before and after treatment. This research confirms that PAC is effective in improving the quality of wastewater from the tofu industry through the coagulation mechanism, producing cleaner and clearer water with a significant reduction.

ABSTRAK Tanaman kayu putih (Melaleuca cajuputi) merupakan tanaman produksi hasil hutan bukan kayu yang pada umumnya dimanfaatkan daunnya untuk menghasilkan minyak kayu putih. Pengrajin minyak atsiri di Koperasi Pondok Pesantren (KOPPONTREN) Al-Fattah, Desa Negara Ratu Kecamatan Natar Kabupaten Lampung Selatan yang merupakan mitra pengabdian telah melakukan usaha pengolahan minyak kayu putih melalui penyulingan sederhana. Namun, rendemen yang dihasilkan hanya berkisar 0,6 – 0,7%. Selain itu, timbulnya limbah hasil pengolahan, murahnya harga jual karena kualitas yang belum baik dan kurangnya pemasaran produk melatarbelakangi kegiatan pengabdian kepada Masyarakat (PkM) ini. Pada kegiatan ini dilakukan peningkatan kualitas produk minyak kayu putih melalui pembuatan alat redistilasi. Sosialiasi pengolahan limbah padat dan cair dalam reaktor SSF Constructed Wetland dengan tanaman rumput wlingi juga dilakukan. Selain itu, pelatihan pemasaran secara digital dan pembuatan desain kemasan dilakukan sebagai pelengkap kegiatan PkM ini. Secara keseluruhan, hasil pelatihan menunjukkan bahwa 86% peserta mengalami peningkatan kemampuan yang signifikan dengan nilai post-test rata-rata 83,8. Hasil ini cukup menggembirakan yang artinya pelaksanaan kegiatan sosialisasi dan praktek penyulingan minyak kayu putih, pengolahan limbah cair dan padat, serta branding produk mampu diikuti dengan baik oleh mitra. Kata Kunci: Branding Produk, Minyak Kayu Putih, Pengolahan Limbah, Redistilasi. ABSTRACT The eucalyptus plant (Melaleuca cajuputi) is a non-timber forest product that is generally utilized for its leaves to produce eucalyptus oil. Essential oil craftsmen at the Al-Fattah Islamic Boarding School Cooperative (KOPPONTREN), Negara Ratu Village, Natar District, South Lampung Regency, who are our service partners, have been processing eucalyptus oil through simple distillation. However, the produced yield is only around 0.6–0.7%. Additionally, the generation of processing waste, the low selling price due to poor quality, and the lack of product marketing are the reasons behind this Community Service (PkM) activity. This activity improved the quality of eucalyptus oil products by creating a redistillation device. Socialization of solid and liquid waste treatment in the SSF Constructed Wetland reactor with wlingi grass plants was also conducted. In addition, digital marketing training and packaging design creation were conducted as a complement to this PkM activity. Overall, the training results show that 86% of participants experienced a significant improvement in their abilities, with an average post-test score of 83.8. This result is quite encouraging, meaning that the implementation of socialization activities and practices of eucalyptus oil distillation, liquid and solid waste processing, as well as product branding, can be well followed by partners. Keywords: Product Branding, Eucalyptus Oil, Waste Processing, Redistillation.
