One of the efforts to minimize the impact of detergent waste pollution is by adsorption using coffee dregs and coconut dregs adsorbents. The purpose of this study was to determine the optimum mass of coffee grounds and coconut pulp as adsorbents, to compare the effectiveness of their absorption in decreasing levels of Linear Alkyl Benzene Sulfonate, and to study their adsorption isotherm models. This research was conducted in batches with variations in the mass of each adsorbent, namely 1 gram, 2 grams, 3 grams, 4 grams and 5 grams. This research was conducted in batches with variations in the mass of each adsorbent, namely 1 gram, 2 grams, 3 grams, 4 grams and 5 grams. The detergent waste samples were contacted with the adsorbent for 30 minutes and then the absorption capacity was tested using the Methylene Blue test method. The results showed that the optimum absorption of LAS content from coffee grounds and coconut pulp adsorbents occurred at a mass of 2 grams with the greatest increase in absorption efficiency index Coconut dregs adsorbent is more effective than coffee dregs because it can absorb up to 37%, while coffee dregs are only 10% with the same adsorbent mass of 5 grams. The adsorption isotherm model of the 2 types of adsorbents refers to the Langmuir equilibrium with R2 values for coffee grounds 0.8651 and coconut pulp 0.9868.

Dewasa ini pencemaran air mengalami peningkatan secara tajam seiring dengan peningkatan jumlah penduduk. Pencemaran air ini disebabkan berbagai hal, salah satunya akibat limbah deterjen. Deterjen yang banyak digunakan di Indonesia adalah jenis Dodecyl Benzene Sulfonate (DBS) yang sangat sulit terdegradasi secara biologis. Belakangan telah diketahui ampas kelapa memiliki kandungan polisakarida yaitu selulosa. Ampas kelapa memiliki struktur berpori dan kandungan kimia selulosa 16 %, mannan 26 %, dan galaktomanan 61 %. Selulosa dan galaktomanan merupakan polisakarida yang mengandung gugus –OH sehingga dapat digunakan sebagai adsorben. Penelitian ini bertujuan untuk mengetahui tinggi dan ukuran adsorben terbaik pada kolom dalam menurunkan kandungan senyawa DBS yang terdapat dalam limbah deterjen. Penelitian dilakukan dengan memasukkan adsorben setinggi 10 cm ke dalam kolom kemudian dimasukkan limbah deterjen hingga adsorben terendam oleh cairan. Diambil beberapa sampel larutan deterjen tiap selang waktu 20 menit lalu dianalisa menggunakan spektrofotometer Uv-Vis untuk mengetahui konsentrasi DBS yang ada di dalam larutan. Prosedur ini dilakukan untuk variasi tinggi 20 cm, 30 cm, dan 40 cm, variasi ukuran -6/+10 mesh, -10/+20 mesh dan -20/+50 mesh. Dari hasil penelitian dapat dilihat bahwa pengolahan limbah deterjen menggunakan arang ampas kelapa dengan tinggi bed 40 cm terjadi penurunan konsentrasi cukup besar yaitu 27,6447 ppm; tinggi bed 30 cm=15,0789 ppm dan tinggi bed 20 cm = 12,8657 ppm, sehingga tinggi bed adsorben terbaik yaitu 40 cm. Untuk penurunan konsentrasi DBS dengan ukuran adsorben -6/+10 mesh = 21,4895 ppm; -10/+20 mesh= 24,2289 ppm dan -20/+50 mesh= 25,7 ppm, sehingga arang ampas kelapa yang terbaik yaitu ukuran -20/50 mesh.

Banana production in Bontang City has increased every year. Along with the high productivity of bananas, the amount of banana peel waste will also increase. In general, waste in the form of banana peels is only used as animal feed or disposed of without further processing so that it can cause environmental pollution. For this reason, it is necessary to manage banana peels so that they have a higher economic value. Banana peel contains alkaloids, flavonoids, phenols, tannins and saponins. This Saponin will produce foam so that it can be used as a washing agent and can also be used as a kitchen equipment cleaner. The samples in this activity were ripe banana peels and orange peels as additives (fragrances and essential oil producers). The method used in the Activities for the Community is the presentation of the material. Discussion, and practice of making dish soap. Participants were very enthusiastic in participating in a series of training activities for making dish soap. The result of this training is an environmentally friendly dish soap product according to the method provided.

The ideal quality of lubricant can be obtained by adding additives. One of the functions of additives in lubricants is to maintain viscosity against temperature changes. Dithiocarbamate complexes with heavy metals have very low solubility in water so that dithiocarbamate compounds have great potential as additives in lubricants. This research was conducted in an effort to determine the effect of temperature (40 oC and 100 oC) on the viscosity of the lubricant and metal ions (Mn2+, Fe3+, Co2+) in the synthesis of dithiocarbamate complex compounds on their potential as additives in lubricants. This compound was synthesized by in situ method and to measure and compare the viscosity of the lubricant before and after the addition of the complex compound as an additive.The results showed that complex compounds from N-ethylisopropylditiocarbamate ligands could be synthesized with metal ions Mn(II), Fe(III) and Co(II). Where is the synthesis of complex compounds obtained yields Mn(II)-N-ethylisopropylditiocarbamate amounted to 49.59%, Fe(III)-N-Ethylisopropyldithiocarbamate of 41.81%,and Co(II)-N-Etilisopropil ditiocarbamate by64.12%.From the results of the characterization of the viscosity test, it can be seen that temperature and metal ions in complex compounds affect their potential effectiveness as additives in lubricants. Of the three complex compounds it is more effective at 100 oC than 40 oC, where metal ions Mn (II) are more effective than Fe(III) and Co (II). Keywords: Lubricants, additives, metal ions, temperature, dithiocarbamate.
