Abstract

Limbah kotoran sapi adalah sumberdaya peternak yang belum termanfaatkan. Peternak umumnya mengatasi limbah kotoran sapi dengan cara membuang ke sungai atau membakar limbah kotoran sapi. Dua hal tersebut dapat menimbulkan permasalahan lingkungan yang kompleks, dengan demikian diperlukan solusi untuk menangani hal tersebut yaitu dengan cara mengolah limbah kotoran sapi menjadi barang yang memiliki manfaat. Salah satu solusinya yaitu mengolah limbah kotoran sapi menjadi pupuk kandang menggunakan bahan Ni35 dimana bahan ini dapat mempercepat dekomposisi limbah padat kotoran sapi menjadi pupuk kandang. Metode yang digunakan dalam pengabdian ini dimulai dari penyuluhan, pelatihan, monitoring, dan evaluasi pelaksanaan produksi pupuk dan hasil uji pada tanaman kangkung dan cabai. Hasil pelaksanaan pengabdian menunjukkan bahwa peserta sangat antusias dalam mengikuti serangkaian kegiatan, serta dapat memproduksi pupuk kandang dengan kemampuan yang dapat bersaing dengan pupuk kandang konveksional/komersil. Cow manure is an underutilized resource among farmers. Generally, farmers address cow manure waste by discarding it into rivers or burning it. Both practices can lead to complex environmental problems. Thus, solutions are needed to manage this issue by transforming cow manure into valuable products. One solution involves processing cow manure into organic fertilizer using a substance called Ni35, which accelerates the decomposition of solid cow manure into usable compost. The method used in this community engagement project includes outreach, training, and monitoring, along with evaluating the production process and testing the fertilizer's effects on plants such as water spinach and chili. The results of this initiative show that participants were highly enthusiastic about the activities and successfully produced compost with competitive quality comparable to conventional commercial fertilizers.

Abstract

Alkaloids are a major class of bioactive secondary metabolites commonly found in various natural products, including cocoa (Theobroma cacaoL.) and robusta coffee (Coffea canephora). These compounds have been widely reported to exhibit important pharmacological activities, including antioxidant, antidiabetic, antifungal, and antibacterial effects, making them valuable candidates for the development of pharmaceutical and functional herbal products. This study aimed to provide reliable quantitative data on the total alkaloid content of ethanolic extracts from cocoa (Theobroma cacao L.) and robusta coffee (Coffea canephora) beans using the TLC-densitometric method, thereby supporting the standardization, quality control, and potential pharmaceutical applications of these natural materials. However, alkaloid was extracted and fractioned from cocoa and robusta coffee beans using ethanol and chloroform. The total alkaloids in the ethanolic extracts of cocoa and robusta coffee beans were identified by TLC-Densitometry, with average Retardation factors (Rf) of 0.321 and 0.771, respectively. Caffeine was used as a standard. The quantification of total alkaloid in the ethanolic extract of cocoa and robusta coffee beans was 2.003% per 50 mg and 11.713% w/w per 10 mg extract, respectively. In summary, cocoa and robusta coffee beans show promising potential as herbal medicines because they contain substantial levels of pharmacologically active alkaloid compounds.

Abstract

Coriander (Coriandrum sativum) is one of the medicinal plants which is known to contain secondary metabolites such as flavonoids, tannins, terpenoids, saponins, steroids, and alkaloids. Alkaloids have therapeutic effects as antimalarials and cancer. Research in determining the alkaloids in coriander was carried out by separating the alkaloids from other substances using the soxhlet method extraction with two solvents ethanol and n-hexane. The total alkaloid content is determined using a UV-VIS spectrophotometer at wavelength 351,5 nm. The reaction of alkaloids with Bromocresol green (BCG) is obtained to form a yellow product. The use of berberine standard was obtained the total alkaloid content of ethanol and n-hexane extract in coriander seed (Coriandrum sativum) were 0.524% and 0.583% respectively, and the ratio of total alkaloid content of ethanol extract was smaller than that of n-hexane extract.
