Perubahan iklim yang sangat ekstrim telah berdampak kepada terjadinya berbagai fenomena penyimpangan cuaca dapat terjadi secara alami maupun karena adanya aktifitas manusia. Salah satu dampak yang sangat dirasakan masyarakat petani adalah tidak sehatnya pertumbuhan tanaman penunjang kehidupan rumah tangga seperti hortikultura, serta tanaman pertanian dan perkebunan lainnya. Hal ini mengakibatkan adanya penurunan pendapatan sehingga dapat berdampak kepada peningkatan angka kemiskinan. Tujuan dari kegiatan pengabdian kepada masyarakat ini adalah melakukan edukasi dan pelatihan pembuatan pupuk bokashi dari bahan organik seperti limbah dan sampah yang tersedia di sekitar masyarakat. Kegiatan pengabdian kepada masyarakat ini dilaksanakan di aula kantor desa Luba Kecamatan Lembur Kabupaten Alor. Kegiatan ini dilaksanakan dalam dua tahapan yakni ceramah dan praktik. Kegiatan ini dihadiri oleh aparat desa Luba dan perwakilan kelompok tani desa Luba. Hasil pelaksanaan pengabdian kepada masyarakat menunjukkan bahwa setelah mendengarkan penjelasan dari narasumber, masyarakat perwakilan kelompok tani desa Luba dengan antusias bersama tim pengabdian menyediakan bahan-bahan pembuatan pupuk bokashi, seperti rerumputan dan dedaunan, batang pisang, serbuk kayu hasil gergaji, kotoran hewan, air bekas cucian beras, dan EM-4. Kelompok masyarakat perwakilan kelompok tani desa Luba dengan penuh semangat melakukan praktik pembuatan pupuk bokashi sesuai prosedur yang telah diuraikan dalam ceramah. Pelaksanaan pengabdian kepada masyarakat ini memiliki kelebihan dan kekurangan. Kelebihannya adalah pelatihan ini tidak hanya menyampaikan materi melalui ceramah saja tetapi sampai kepada tahapan melakukan praktik. Sedangkan kekurangannya adalah kegiatan ini dilakukan hanya sampai pada tahap prosess dan output saja tetapi tidak sampai kepada tahap outcome. Oleh karena itu untuk pengabdian kepada masyarakat selanjutnya terkait pembuatan pupuk bokashi ini sebaiknya sampai kepada outcome sehingga dapat diketahui dampaknya kepada peserta.

In this research, a study of the adsorption kinetics of heavy metal Pb(II) with white sand adsorbent has been carried out. The use of white sand as an adsorbent is based on the habits of the people who use white sand to purify water. For wider use, in this study, it was used to adsorb lead metal which has a high toxicity. Increased the adsorption power of white sand, chemical activation was carried out using NaOH with various concentrations of 2, 4 and 6 M. Adsorption kinetics of Pb(II) by adsorbents were carried out using a batch system with time variations of 15, 30, 60, 90, 120 minutes. The behavior pattern of Pb(II) absorption by the adsorbent was studied using first-order, second-order kinetic models, pseudo-first-order Lagergren's equation and pseudo-second-order Ho's equation. The results showed that the absorption of Pb(II) by sand adsorbents in various variations, both control and activated NaOH 2, 4 and 6 M, followed a pseudo-second-order adsorption kinetics with a coefficient of determination (R2) of 1. In addition, based on kinetic studies pseudo second order there is no value comparison between qe, exp and qe, hit. The highest k value was found in the 4 M NaOH activated sand adsorbent, which was 206.921 g/mg.h, indicating a faster absorption rate of the adsorbate by the adsorbent. Thus, the activation of the adsorbent at variations in base concentration affects the surface area of the adsorbent where the greater the surface area, the faster the absorption rate of Pb(II).

The fabrication of slow-release urea fertilizer beads using chitosan and chitosan-biochar as coating materials has been accomplished. The beads were synthesized by solidifying chitosan-urea and chitosan-biochar-urea hydrogels in a NaOH solution. Characterization of the chitosan-urea composite beads (BKU) and chitosan-biochar-urea beads (BKBU) was conducted through Fourier-transform infrared (FTIR) spectroscopy, along with water intake (swelling) and nitrogen release tests in aqueous media at time intervals of 24, 72, 120, and 168 hours. The FTIR spectra of BKU and BKBU beads displayed functional group peaks associated with biochar (hydroxyl and carboxylate), chitosan (amine and hydroxyl), and urea (amine and carbonyl), along with others supporting group. Water intake rates were 72% for BKU and 81% for BKBU, which impacted nitrogen release patterns. BKU exhibited a faster nitrogen release compared to BKBU, indicating that BKBU is more suitable for use as a slow-release fertilizer due to its more gradual nitrogen release mechanism

Herbal plants have been used since ancient times in traditional medicine and continue to be maintained and preserved in Indonesia. They are called Jm. Each part of an herbal plant has active components in the form of secondary metabolite compounds, ranging from tubers, wood, sap, latex, leaves, flowers, fruits, and seeds that function to maintain life in their environment. Turmeric, ginger, and lemongrass are included in Jm plants, which are very useful in traditional medicine because they have various secondary metabolite compounds. This study aims to obtain an even distribution of secondary metabolite compounds through phytochemical tests, inhibition of free radicals through antioxidant activity tests, and an even distribution of nutrients through proximate analysis in JKHS samples with a certain formula. The results of the phytochemical test showed that JKHS contains several important phytochemical components with the intensity it shows. Phenolic content (++) can provide benefits in protecting body cells from oxidative damage. Saponin (+) has anti-inflammatory properties and has the potential as an antimicrobial agent. In addition, steroids (+) and terpenoids (++), play a role in regulating the body's physiological functions and can support hormonal balance and the immune system and the potential in treating certain diseases. Alkaloid content (+)can affect the nervous system and has analgesic and stimulant properties. JKHS samples also contain carotenoids (+), which protect body cells from free radicals and oxidative damage. With the value of 4.838 µg / mL of the sample, it shows that JKHS extract has very strong antioxidant potential. Through proximate analysis, it was obtained that the water content (15.38%) reflects the humidity level in JKHS which can affect the stability of product storage, the ash content (6.29%) indicates that JKHS can be a good source of minerals to support health, the crude protein content (3.79%) indicates that JKHS contributes to daily protein intake, especially in regular consumption, the fat content (6.43%) contributes energy and plays an important role in the absorption of fat-soluble vitamins and other bioactive compounds that may be contained in JKHS, the carbohydrate content (81.37%) indicates that the main component of JKHS is carbohydrates, which function as the main source of energy for the body that can support physical activity and daily energy needs, and the fiber content (5.45%) is an important component that helps smooth the digestion process, improves intestinal health, and helps prevent digestive disorders such as constipation, and plays a role in maintaining blood sugar levels and supporting weight management. Overall, the proximate composition of JKHS has good nutritional value, with carbohydrates as the dominant energy source, as well as additional protein, fat, and fiber that support overall health. This combination of formulas makes JKHS have great potential as a Jm drink that can provide various health benefits, especially in protecting the body from oxidative stress, inflammation, and other disease risks, including supporting the regeneration of cells, nerves, and other organs of the body that are weak due to climate, work, or old age.

The dependence of optical microscopes on one of the consumables, especially at high magnification, so that the imaging results are clearly visible or not blurry, is immersion oil. In an effort to answer this need, a study has been conducted to find an alternative immersion oil by utilizing vegetable oil from the kepuh plant (Sterculia Foetida L) from Alor Regency. This study tested the quality of kepuh seed meat oil from soxhlet extraction and purified using the Deguming, Neutralization, Bleaching, Stearin, Centrifugation methods, and stored in glass bottles, wrapped in aluminum foil, and stored at room temperature (25-280C) from 2016 to 2024 (8 years). The test used three parameters, namely first; comparison of physical and chemical properties parameters, namely density, viscosity, refractive index, acid number and Aperture Value for kepuh oil data in 2016 and 2024, were recorded to have changed, but the imaging photographs still provided the same brightness as standard oil. Second; the GC-MS identification parameters showed that, even though there were 32 peaks in the kepuh oil spectrum, and the nomination of two compounds was identified, namely linoleic acid 34.58%, stearic acid 6.98%, the imaging effect was still clearly visible. Third, a comparison of the imaging results of standard immersion oil and immersion oil from kepuh for oil conditions in 2024 showed imaging results that were not significantly different.

Salah satu alternatif dalam pengurangan pencemaran lingkungan akibat adanya limbah cair tahu yaitu penggunaan eco-enzyme sebagai agen bioremediasi. Eco-enzyme merupakan cairan filtrat hasil fermentasi bahan organik, gula molase, dan air. Penelitian ini bertujuan untuk mengetahui waktu dan konsentrasi terbaik eco-enzyme kulit nanas dan kulit jeruk purut dalam meningkatkan nilai pH, serta menurunkan nilai TDS dan COD limbah cair tahu. Metode penelitian yang digunakan yaitu eksperimen dengan konsentrasi eco-enzyme dan waktu penyimpanan sampel sebagai variabel bebas. Cairan/filtrat eco-enzyme kulit jeruk purut dan kulit nanas yang diperoleh memiliki karakteristik berwarna kuning kecokelatan, beraroma asam segar, memiliki nilai pH 6, TDS 113 mg.L-1, dan COD 2.260 mg.L-1. Limbah cair tahu sebelum perlakuan memiliki nilai pH 6, TDS 1.210 mg.L-1, dan COD 1.340 mg.L-1. Hasil pengamatan menunjukkan terjadi penurunan nilai pH hingga 4 pada sampel limbah cair tahu kontrol tanpa penambahan eco-enzyme setelah 20 hari penyimpanan. Hasil perlakuan penambahan eco-enzyme pada limbah cair tahu menunjukkan bahwa eco-enzyme dengan konsentrasi 10% selama 20 hari penyimpanan dapat meningkatkan nilai pH dari 4 menjadi 6. Eco-enzyme dengan konsentrasi 15% dengan penyimpanan selama 10 hari mampu menurunkan nilai COD dari sampel kontrol dengan COD 2.070 mg.L⁻¹ menjadi 50 mg.L⁻¹. Penambahan eco-enzyme pada penelitian ini tidak menurunkan nilai TDS, namun meningkatkan nilai TDS (untuk penyimpanan 20 hari dari 945 mg.L⁻¹ menjadi 1.220 mg.L⁻¹). Hal ini menunjukkan bahwa eco-enzyme memiliki potensi menurunkan nilai COD dan meningkatkan nilai pH karena memiliki kandungan enzyme yang berperan sebagai biokatalis yang mempercepat dekomposisi limbah cair tahu.
