Abstract

Kematian akbat hipertensi di Indonesia diketahui sebesar 427.218 orang dengan rentang kelompok usia 31-44 tahun (31.6%), 45-54 tahun (45.3%) dan usia 55-64 tahun (55.2%). Kejadian hipetensi di Nusa Tenggara Barat pada tahun 2022 mencapai 282.97. orang berdasarkan data pelayanan Kesehatan Penderita Hipertensi dipelayanan Puskesmas. Kejadian hipertensi di kabupaten Lombok Tengah menjadi kejadian hipertensi tertinggi kedua di NTB dengan kejadian hipertensi sebesar 45.887 orang. Faktor yang mempengaruhi terjjadinya hipertensi salah satunya adalah obesitas yang ditandai dengan adanya peningkatan indeks massa tubuh. Penelitian ini bertujuan untuk mengetahui hubungan Indeks Massa Tubuh dengan hipertensi pada peserta lansia di desa Dasan Tapen Kecamatan Gerung. Penelitian merupakan penelitian observasional analitik dengan pendekatan cross-sectional single site study. Peserta dalam penelitian ini sebanyak 45 orang lansia dengan rentang usia diatas 60 tahun, diketahui sebanyak 60% dari peserta terjadi peningkatan IMT dengan kategori obesitas Tingkat 1(31.1%) dan obesitas Tingkat 2 (13.3%). Analisis hubungan dalam peneliitian ini dilakukan secara uji statistic rank spearman rho yang diperoleh nilai signifikan α = 0.000 sehingga dapat disimpulkan adanya hubungan antara peningkatan IMT dengan kejadian hipertensi di desa Dasan Tapen Kecamatan Gerung.

Abstract

Writing a research proposal is a crucial first step in determining the success of your research project. However, authors often face challenges in formulating proposals that are clear, relevant, and persuasive. The purpose of this service is to help researchers, especially young researchers in making research proposals. The method of implementing this service uses a Coaching Clinic, discussion, and mentoring which is carried out in a hybrid manner with pre-test and post-test.  Participants in this Coaching Clinic were young lecturers from Politeknik Medica Farma Husada Mataram and several other universities who participated online. There were 20 participants and it was held online through a Zoom meeting on December 16, 2023. The main target of this activity is young lecturers who have minimal experience writing research proposals. The results of this service show an increase in lecturers' abilities or skills and understanding in writing research proposals by 84.50%. Coaching clinics can improve the ability of lecturers to write research proposals.

Abstract

Permasalahan limbah merupakan salah satu masalah lingkungan yang masih belum terselesaikan hingga saat ini. Sebagian besar permasalahan limbah berasal dari limbah rumah tangga, baik limbah organik maupun anorganik. Limbah anorganik dapat didaur ulang kemudian dijual dan menghasilkan sumberdaya, sedangkan limbah organik banyak yang belum diolah dan dimanfaatkan dengan baik. Pengelolaan limbah yang belum optimal seringkali disebabkan oleh kurangnya informasi dan edukasi mengenai cara mengelola limbah. Padahal jika limbah rumah tangga dikelola dengan baik bisa bernilai ekonomis. Limbah organik dapat diolah dengan cara membuat eco-enzyme dan produk turunannya yang ramah lingkungan. seperti sabun cair eco-enzyme. Tujuan dari kegiatan pengabdian kepada masyarakat ini adalah untuk memberi edukasi dan pelatihan pengolahan eco-enzyme menjadi produk sabun cair eco-enzyme sehingga dapat meningkatkan pemahaman masyarakat tentang pengelolaan limbah organik yang bernilai ekonomis. Kegiatan pengabdian dilakukan di Kabupaten Lombok Barat, diikuti oleh tim pengabdian dan 30 peserta mahasiswa Politeknik Medica Farma Husada Mataram dengan rangkaian kegiatan inti yaitu pemanenan eco-enzyme dan pelatihan pembuatan sabur cair eco-enzyme. Tim pengabdian mengajarkan cara memanen eco-enzyme dengan benar dari hasil pembuatan 3-6 bulan sebelumnya. Setelah pemanenan selesai, dilanjutkan pembuatan sabun cair eco-enzyme dengan bahan seperti MES, garam, air panas, gliserin dan larutan eco-enzyme. Kegiatan pengabdian ini disambut antusias oleh para peserta. Kegiatan ini diharapkan dapat menjadi referensi untuk mengolah limbah organik menjadi lebih bermanfaat dan dapat menghasilkan produk-produk yang lebih ramah lingkungan dan berkelanjutan.

Abstract

Acid-base indicator paper is a type of paper that changes color when exposed to an acid or base solution, used to distinguish the properties of a substance as either acidic or basic. Several studies have been conducted to find alternative plants that can be used as acid-base indicators.One of them is the butterfly pea flower. The need for practical and economical indicator testing tools prompted researchers to test indicator paper that is cheaper compared to litmus paper. The paper tested comes from commonly found paper in the surroundings, namely HVS paper, BC paper, and Whatman paper. Research objective: Creating Kerinlang, an innovative alternative paper for acid-base indicators using the Telang flower (Clitoria Ternatea). Research method: Maceration of Butterfly Pea Flower is carried out with a 70% ethanol solution to produce an extract from the butterfly pea flower (Clitoria ternatea). The ethanol extract of butterfly pea flower (Clitoria ternatea) was soaked using HVS paper, BC paper, and Whatman paper, then tested with acid-base test solutions to observe the resulting color changes as well as the structure and durability of the tested paper. Conclusion: Kerinlang can be used as an alternative pH indicator paper for butterfly pea flower (Clitoria ternatea) with Whatman paper as the medium, which produces the best color change, is durable, and inexpensive.

Abstract

Banana peels are often considered waste despite being rich in bioactive compounds with potential as natural antioxidants. This study aimed to evaluate the antioxidant activity of an ethanol extract combination of Cavendis banana peel (Musa acuminata) and Kepok banana peel (Musa paradisiaca) using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The extraction process was conducted using 96% ethanol maceration, yielding an extraction efficiency of 9.13%. Phytochemical screening revealed the presence of flavonoids, tannins, saponins, and steroids/terpenoids in the extract. Antioxidant activity was assessed through the DPPH method, resulting in an IC50 value of 6.47 ppm and an AAI value of 5.40, classified as very strong antioxidants. These results are comparable to the positive control (Vitamin C), which had an IC50 value of 6.29 ppm and an AAI value of 5.56. The findings suggest that the ethanol extract combination of Cavendis and Kepok banana peels has significant potential as a natural antioxidant source applicable in the food, pharmaceutical, and cosmetic industries. Recommendations for future research include optimization of extraction methods, isolation of key active compounds, in vivo testing, and functional product formulation development to maximize the extract's potential.

Abstract

Banana peels, often considered agricultural waste, are rich in bioactive compounds with significant antioxidant potential. This study evaluates the antioxidant activity of a combined ethanol extract from Cavendis (Musa acuminata) and Kepok (Musa paradisiaca) banana peels using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The extraction was performed via maceration with 96% ethanol, yielding 9.13%. Phytochemical analysis identified key compounds including flavonoids, tannins, saponins, and steroids/terpenoids, which are known to exhibit antioxidant properties. The extract demonstrated strong radical scavenging activity with an IC50 of 6.47 ppm and an Antioxidant Activity Index (AAI) of 5.40, comparable to Vitamin C (IC50 = 6.29 ppm; AAI = 5.56). These results indicate a synergistic effect from combining the two banana peel varieties, enhancing antioxidant efficacy beyond that reported for individual peels. This study supports the potential use of Cavendis and Kepok banana peel extracts as sustainable natural antioxidants for application in food preservation, nutraceuticals, and cosmetics. Future work should focus on optimizing extraction methods, detailed phytochemical profiling, stability assessment, and in vivo validation to advance product development and maximize health benefits.
