Abstract

Meat is one of the most foodstuff consumed. The increasing consumption of meat had led some traders to falsify the identity of meat for gaining profit. The meat adulteration case that often occurs is substituting the beef with pork. This adulteration case is very detrimental to consumers, therefore a method to identify the type of meat sold is very necessary. The vibration spectroscopy method, Fourier Transform Infra Red (FTIR), had been developed to analyze the type of beef and pork. The FTIR measurement was carried out with cut raw meat samples without further preparation. The Data obtained from the measurement are infra-red spectrum from beef and pork from 4000-500 cm-1 wavenumber and then the data was analyzed with Principle Component Analysis (PCA) statiscticall method. Projection result with PCA obtained data reduction that can represent all data generated from measurements shown through the Principle Component 1 and Principle Component 2 regions. Based on those projection, beef and pork profile area can be classified properly.

Abstract

The research attempts to examine the effect of waters salinity and carbon organic total in the Lapindo Mud on the fluctuation of heavy metals Cu and Pb in the waters of Aloo Rivers. Sample is taken from Lapindo Mud from four different locations. Result of the characterization of Lapindo Mud shows that the clay and dust contents are 34-35 % and 39-46 %. Lapindo Mud texture is clay loam. The organic matter in Lapindo Mud is not surely increasing the concentration of heavy metal because there is oxide compound with great contribution to the increase of heavy metal concentration in Lapindo Mud. Result of TOC analysis indicates that the organic carbon ranges from 54.7 % to 55.47 %, Pb rate ranges from 0.27-0.34 mg/L, and Cu rate ranges from 0.83-1.31 mg/L. Indeed, Pb has higher metal flux in salt water at AL from 5x10-5 mg/cm2.hour to 9x10-5 mg/cm2.hour. Cu has higher metal flux in freshwater at SA1 2.3x10-6mg/cm2.hour to 8.71x10-5mg/cm2.hour

Abstract

This community service is held to improve the quality of human resources and the economy of the people in Barabali Village by raising the potential of Barabali Village which has an abundance of natural resources in the form of bamboo. The availability of raw materials, in this case bamboo, is a supporting factor that provides the opportunity and potential to be used as a product that has economic value. Based on field observations, the wealth of natural resources in the form of bamboo has not been utilized optimally. The business that has been running so far does not have a variety of product varieties so that its market share is limited, production creativity is still low so it does not have high selling power. In this activity, innovations and new creations of bamboo products were introduced which were adapted to the latest market trends. This will open up a new market for the creative industry, especially bamboo handicrafts and can have a positive impact on the people's economy. The participants in this Community Empowerment activity were members of the Barabali Village Women Farmers Group (KWT) with a high level of participation and this had a positive impact on the implementation of the activity. At the end of the activity, the participants gained soft skills in making products and were able to produce several variations of bamboo handicraft products in the form of door ornaments, night lamps and bamboo mugs.

Abstract

Desa Genggelang merupakan desa terluas di Kecamatan Gangga, Kabupaten Lombok Utara. Desa Genggelang menjadi salah satu desa wisata prioritas, yang memiliki landscape sumber daya yang lengkap. Mayoritas mata pencaharian masyarakat adalah sebagai petani yang mengelola perkebunan dan peternakan. Pada sektor peternakan, Desa Genggelang memiliki keunggulan di bidang budidaya kambing etawa. Pelatihan pembuatan kompos berbahan dasar kotoran kambing etawa bertujuan untuk memberikan pemahaman dan keterampilan kepada masyarakat kelompok tani ternak mengenai teknik pengolahan limbah organik, khususnya kotoran kambing etawa, menjadi kompos berkualitas tinggi. Kotoran kambing etawa kaya akan unsur hara yang penting bagi tanaman, sehingga dapat dimanfaatkan sebagai pupuk organik yang ramah lingkungan dan berkelanjutan. Metode pelaksanaan pelatihan meliputi pemaparan teori, diskusi dan praktik langsung, mulai dari pengenalan bahan baku, proses fermentasi, hingga aplikasi kompos dalam pertanian. Melalui pelatihan ini, diharapkan peserta dapat meningkatkan produktivitas lahan pertanian mereka serta mendukung upaya pengelolaan limbah organik secara efektif. Hasil yang didapatkan pada kegiatan ini yaitu terdapat 80% peningkatan keterampilan dan kesadaran akan pentingnya penggunaan pupuk organik dalam pertanian berkelanjutan dengan memanfaatkan kotoran kambing etawa.

Abstract

This study investigated the antioxidant activity of swallow nests known as Edible Bird Nests (EBNs) derived from the swallow species Collocalia linchi, especially those sourced from Lombok, Indonesia with various health benefits, including their potential as antioxidants. This study used swallow nest samples taken from 3 different locations, namely: East Lombok, Central Lombok and West Lombok. The extraction method used is heating and sonication. Antioxidant activity was assessed quantitatively using the DPPH method and measured by UV-Vis spectrophotometry. Results showed varying IC50 values across different extraction times, with the highest values recorded at 3818.47 mg/mL and the lowest at 2331.47 mg/mL, compared to the control (ascorbic acid) at 35.22 mg/mL. The higher the IC50 value, the lower the effectiveness of antioxidants and vice versa. These findings suggest that the antioxidant activity of EBNs extracts is relatively weak when compared to ascorbic acid. This study contributes to the understanding of optimized extraction techniques by heating and sonication to unlock the full potential of the extraction results of bioactive compounds.

Abstract

This community service activity aims to increase the understanding and skills of community members in utilizing livestock waste for sustainable food sources to handle stunting in Gelangsar Village, West Lombok Regency. The method of implementing this activity was through KOSABANGSA program outreach, training, and mentoring. The evaluation instrument for this activity used an environmental observation sheet and assesses the participation and activeness of participants during the activity. The results of this service activity showed that the community has the ability to process cowshed waste (solid) into 40 bags of compost, create a sustainable food house area using polybags in 8 groups spread throughout the village, and one KRPL point on land with an area of around 250 m2, and the types of plants were spinach, tomatoes, eggplant, chilies, mustard greens, lettuce, basil, long beans, family medicinal plants, and others. Guidance and assistance need to be continued considering that the community was very enthusiastic about being able to overcome stunting in Gelangsar village and at the same time wants to become an organic vegetable producer.
