Abstract

The Nekamese region has the potential for coconut trees that are traditionally converted into coconut oil. Traditional coconut oil is of poor quality in terms of health and requires a lot of energy to produce. While coconut can be processed into pure oil and when sold, it will be more expensive. One way to process virgin coconut oil is by fermentation. Such knowledge is exactly what the community needs. But the partners do not have knowledge about processing pure coconut oil. Therefore, the proposed solution for partners is to organize training on pure coconut oil production.

Abstract

This study aims to investigate the production and characterization of the chemical composition of various quality classifications of liquid smoke that is derived from lontar Shells. Liquid smoke is generated from dried lontar shell raw material that takes on pyrolysis at approximately 400 ℃. A vertical column-model pyrolyzer equipped with a 6-meter-long spiral-shaped condenser supports the productivity of the pyrolysis process. After being collected, the liquid smoke is allowed to settle for a duration of seven days. The process involves distillation at 130℃, followed by purification through a zeolite column and activated charcoal derived from lontar shells, resulting in grades 3, 2, and 1. The characterization of the chemical composition of each liquid smoke grade was conducted using GC-MS, in addition to the determination of acidity via acid-base titration. The findings indicate that the average yield of liquid smoke derived from dried lontar shells is 44.35% of the weight of the initial raw material. The composition of grade 3 liquid smoke includes p-cresol at 18.28%, phenol (2-methyl) at 14.79%, and phenol (2-methoxy) at 10.09%. It also has an acid content of 5.97% and contains a total of 50 compounds. The acid content of grade 2 liquid smoke is 8.70%, with p-Cresol being the most dominant component at 20.70%. Other significant constituents include phenol, 2-methoxy at 14.51%, and phenol, 3-methyl at 11.69%. The acid content of grade 1 liquid smoke is measured at 9.23%. The primary components include p-Cresol at 20.29%, followed by phenol, 3-methyl at 16.36%, and phenol, 2-methoxy at 16.18%.

Abstract

Abstract - Seki Village is a dry land area in the East Nusa Tenggara region where the majority of the population work as farmers. Moringa plants are easy to grow in dry land areas, so they are widely available in Seki village. Scientifically, Moringa that grows in dry land areas in NTT has a higher nutrient content than those found elsewhere. At the time of the survey in the partner area, namely the homes of residents in Seki Village, it was stated that this plant lives very much and is abundant. The problem occurs when the abundant moringa plant is only processed in the form of boiled vegetables so that on average it is disliked by children and adults who consume it. However, if it is processed in an innovative way, it will increase people's interest in consuming it and can improve the economy of the people. This Program of devotion is implemented to provide alternative solutions. External to be achieved: 1) Increased community motivation to be more productive and creative in managing Moringa leaves, 2) Knowing science and technology to produce noodles and cakes made from Moringa leaves, 3) Skilled in making noodles and cakes made from moringa Moringa leaves, 4) Increased business opportunity reference for the people of Seki Village. The program partners are local women who are members of the Ebenhazer Congregation. The program ran smoothly and received support from church leadership. The results obtained 1) This service has a positive impact on the community by introducing the technology of making noodles and cakes made from Moringa leaves as an alternative for consuming Moringa leaves, 2) This program provides skills to partner groups regarding the ways and steps of making noodles and cakes made from moringa Moringa leaves which have the potential as a home industry, 3) still need special attention from various parties to improve the Village Human Resources Seki in maximizing the potential of Moringa leaves. The method used is through a workshop, namely the provision of material and practice of making noodles and cakes made from Moringa leaves by the participants in the activity. Abstrak – Desa Seki merupakan daerah lahan kering di wilayah nusa tenggara timur yang mayoritas penduduknya berprofesi sebagai petani. Tanaman kelor merupakan yang mudah tumbuh di daerah lahan kering sehingga banyak terdapat di desa Seki. Secara ilmiah, kelor yang tumbuh di daerah lahan kering di NTT mempunyai kandungan gizi lebih tinggi dari kandungan gizi yang hidup di tempat lain. Pada saat survei di daerah mitra yaitu rumah warga di Desa Seki bahwa tanaman ini hidup sangat banyak dan melimpah. Masalah terjadi ketika tanaman kelor yang melimpah hanya diolah dalam bentuk sayur yang direbus sehingga rata-rata tidak disukai oleh anak-anak dan orang dewasa yang mengkonsumsinya. Namun bila didiolah secara inovatif maka akan menambah minat masyarakat dalam mengonsumsinya dan dapat meningkatkan perekeonomian warga. Program pengabdian ini dilaksanakan untuk memberikan solusi alternatif yang ingin dicapai yaitu: 1) Meningkatnya motivasi masyarakat untuk lebih produktif dan kreatif dalam mengelola daun kelor, 2) Mengetahui IPTEK memproduksi mie dan kue berbahan dasar daun kelor, 3) Terampil membuat mie dan kue berbahan dasar daun kelor, 4) Meningkatnya referensi peluang usaha bagi masyarakat Desa Seki. Mitra program adalah para ibu-ibu warga sekitar yang tergabung dalam Jemaat Ebenhazer. Program berjalan dengan lancar dan mendapat dukungan dari pimpinan jemaat. Hasil yang diperoleh 1) Pengabdian ini berdampak positif bagi masyarakat dengan memperkenalkan teknologi pembuatan mie dan kue berbahan dasar daun kelor sebagai salah satu alternatif dalam mengkomsumsi daun kelor, 2) Program ini memberikan ketrampilan kepada kelompok mitra terkait cara dan langkah pembuatan mie dan kue berbahan dasar daun kelor yang berpotensi sebagai industri rumah tangga, 3) masih perlu perhatian khusus dari berbagai pihak untuk meningkatkan SDM Desa seki dalam memaksimalkan potensi daun kelor. Metode yang digunakan adalah melalui kegiatan workshop yakni pemberian materi dan praktik membuat mie dan kue berbahan dasar daun kelor oleh peserta kegiatan

Abstract

This study aims to determine the level of toxicity in various categories of liquid smoke from kusambi wood and coconut shells. The liquid smoke produced from the pyrolysis of kusambi wood and coconut shells at ±400 ℃. Liquid smoke resulting from pyrolysis then distilled to achieve grade 3. Grade 3 liquid smoke filtered in zeolite and activated charcoal column to obtain grade 2 and  1 categories. The toxicity test was conducted using the BSLT method of 48-hour-old Artemia salina Leach shrimp larvae. The toxicity level of each liquid smoke was identified by the percentage of shrimp larvae mortality and determination of lethal concentration (LC50). Determination of total phenol content using a Shimadzu UV-Vis 1780 spectrophotometer. The results showed that toxicity of liquid smoke from the pyrolysis of kusambi wood and coconut shells is toxic, with LC50 <1000 ppm, while the Kusumbi wood and coconut shells liquid smoke from distillation processes, grade 2 and grade 1 are non-toxic, with the LC50 > 1000 ppm.

Abstract

This research intends to determine variations in acidity and surface morphology of the catalyst while employing different quantities of Mo and Co. Natural zeolite from Ende-Flores was activated via a hydrothermal method, accompanied by chemical activation utilizing HF, HCl, and NH₄Cl. The K-Co-Mo/ZAAEF catalyst was synthesized by the co-impregnation method utilizing solutions of CoCl₂∙6H₂O, (NH₄)₆Mo₇O₂₄∙4H₂O, and K₂CO₃ as precursor compounds for the metals K, Co, and Mo. The catalyst activation included calcination, oxidation, and reduction procedures at 500 °C, utilizing nitrogen, oxygen, and hydrogen gases, respectively. The catalyst surface acidity was measured using the gravimetric technique with pyridine vapor. The research findings indicate that the acidity of the catalyst varies with varied molar ratios of Mo/Co precursor metals. The catalyst exhibited an increase with varied molar ratios of Mo/Co precursor metals from 0 to 0.6, whereas those with molar ratios over 0.6 showed decreasing values. The K-Co-Mo0.6/ZAAEF catalyst has the highest surface acidity at 0.0946 mmol/gram. The findings from functional group identification via FT-IR indicate that the catalyst comprises Lewis and Brønsted acid sites. A modest quantity of Mo precursor metal, with a Mo to Co precursor metal ratio of 0.3-0.6, yields a catalyst exhibiting an absorption band for Brønsted acid sites; conversely, a higher quantity of Mo precursor metal does not produce this absorption band. Microscopic test results indicate that the surface morphology of the catalysts varies with differing quantities of Mo/Co precursor metals. The K-Co-Mo0.6/ZAAEF catalyst has a well-dispersed surface shape characterized by a more homogeneous particle dispersion relative to the other catalysts.

Abstract

Characterizing the elemental constitution, composition of oxides, and thermal stability of CaO/SiO₂, MgO/SiO₂, and CaO-MgO/SiO₂ catalysts has been the subject of this research. The sol-gel process was used to convert natural zeolite into silica. We used HCl in order for the silica to settle out after dissolving it in NaOH from the zeolite framework. Hard water deposits were transformed into CaO through the sol-gel process. HCl was utilized during the hydrolysis procedure, and Na₂CO₃ was employed during the condensation stage. The mixture was then calcined and dried. When heated, the precursor MgCO₃ breaks down into MgO. CaO and MgO are dispersed using the wet impregnation process onto the SiO₂ support's surface. XRF equipment was used to characterize each material's elemental and oxide composition. TGA was used to examine each catalyst's thermal stability. According to the elemental and oxide composition characterization results, each material had more than 90% major elements and oxides and less than 1% impurities. SiO₂ lost 4% of its weight during the thermal stability test, which was conducted between 30 and 800°C at a rate of 10°C/minute. The weight loss for MgO/SiO₂, CaO, CaO-MgO/SiO₂, and CaO/SiO₂ was 12.5%, 18.14%, 25.27%, and 27.82%, respectively. According to each material's mass loss, SiO₂ > MgO/SiO₂ > CaO > CaO-MgO/SiO₂ > CaO/SiO₂ was the order of thermal stability from most stable to least stable.
