Abstract

Fenomena menunjukkan masih banyak pelaku Usaha Mikro Kecil Menengah (UMKM) yang belum mampu memperoleh laba secara optimal karena ketidakmampuan mereka dalam menghitung harga pokok produksi secara tepat. Hal ini antara lain disebabkan kurangnya kemampuan dalam pengelolaan biaya sehingga terdapat beberapa biaya yang tidak diperhitungkan dalam harga pokok, seperti biaya penyusutan dan tenaga kerja yang berasal dari pemilik sendiri. Sementara ini, mitra belum menjalankan manajemen pengelolaan keuangan yang baik, belum ada pengaturan alokasi belanja modal, belanja barang, pencatatan utang dan piutang, laba, dan seterusnya. Bahkan di dalam pengelolaan keuangan, tidak ada pencatatan sama sekali. Sektor UMKM yang merupakan bagian terpenting dari sektor ekonomi sangat merasakan dampaknya. Inilah yang dikhawatirkan oleh semua pihak, karena telah membuat sektor UMKM mengalami kemunduran yang signifikan. Apalagi saat ini banyak UMKM yang mengalami berbagai permasalahan seperti penurunan penjualan, permodalan, distribusi terhambat, kesulitan bahan baku, produksi menurun dan terjadinya banyak pemutusan hubungan kerja untuk pekerja baru yang kemudian menjadi ancaman bagi perekonomian nasional. Kondisi tersebut mendorong tim Pengabdian kepada Masyarakat Universitas Sang Bumi Ruwa Jurai melakukan pelatihan pengelolaan keuangan agar pelaku UMKM Desa Bernung dapat melakukan perhitungan harga pokok produksi (HPP) dan penentuan harga jual yang tepat sehingga mampu mengidentifikasi penghematan biaya produksi, diharapkan dapat meningkatkan penjualan.

Abstract

Cancer is one of the leading causes of human death. In 2019, it was reported that cancer was the second (22%) cause of death due to non-communicable diseases in the world's population. Research for alternative anticancer drugs is still being done, including anticancer from plants. One of the plants that have the potential to be developed as an anticancer alternative is the sungkai plant. Sungkai leaves contain many bioactive compounds, one of which is the clerodane-type diterpenoids, peronemins, A2 (1), A3 (2), B1 (3), B2 (4), B3 (5), C1 (6), and D1 (7). The aim of this study was to initial screen the potential of seven Peronemins compounds in Sungkai leaves extract as anticancer candidates. Initial screening was carried out by predicting in-silico anticancer activity of the seven compounds. Dihydrofolate reductase inhibitor (DHFR inhibitor) is one of the anticancer activity screening approaches. DHFR Inhibitor activity from perenomins derivatives with pIC50 values ​​of 0.785 (A2), respectively; 0.785 (A3); 0.799 (B2); 0.799 (B3); 0.799 (C1 and D1). In addition, from compounds 1,2,3,4,5 peronemin derivatives have potential anticancer activity through interaction with the target protein Voltage-gated potassium channel subunit while compounds 6, 7 also have biological activity potential anticancer on target protein Dihydrofolate reductase.

Abstract

Putat leaves (Planchonia valida) are a plant that is traditionally used by people in the Tanjung Lanjut areas, Jambi as fresh vegetables, and as a traditional medicine to treat skin diseases and restore health. This identifies that the putat plant contains chemical compounds that have the potential to have antioxidant activity. Extraction was carried out using n-hexane and ethyl acetate solvents using multistage maceration. Next, phytochemical screening and antioxidant activity tests are carried out to obtain information about fractions that can potentially proceed to the isolation stage. In the maceration process, an extract percentage was obtained with a yield value of 1.39%. Next, isolation was carried out using vacuum liquid chromatography. The isolates obtained were then characterized using UV-Vis and FT-IR spectrophotometer instruments. The isolate obtained was in the form of a wet solid, and if seen through characterization, it belonged to the class of steroid compounds; it was suspected to be an ergosterol compound. Antioxidants are known to have the ability to inhibit and reduce the presence of free radicals in the human body. In this study, antioxidant activity was tested using the DPPH (2,2-diphenyl-1-picrihidazil) method on F1 isolates. The F1 isolate obtained was proven to have antioxidant activity with a value of 99.2265 ppm, which is classified in the strong antioxidant activity range.

Abstract

Red Palm Oil (RPO) is the result of refining from Crude Palm Oil (CPO) which still maintains a high level of phytonutrients that are beneficial for health. The benefits of RPO can be used as a nutraceutical source, because RPO acts as a provitamin A and vitamin E. The addition of Lactic Acid Bacteria (LAB) in a product functions as a probiotic with metabolite activity that can inhibit pathogenic microorganism thereby increasing the durability of a product. The addition of LAB to RPO is expected to increase the nutraceutical value by adding probiotic properties to RPO products. Microencapsulation technology can protect the bioactive content of essential oils against unwanted chemical interactions with other components and provide increased stability during processing. This research is expected to be able to provide information about the potential raw material of fermented RPO as a nutraceutical source by showing the profile of RPO before and after the fermentation process, chemical and physical properties of the microencapsulant. The microencapsulation technique used is the extrusion method. Fermentation of the bioactive compound ingredients in RPO using L. casei has a significant effect. RPO after fermentation using L. casei (Red-PalmZym) produces major compounds in the form of 9-Octadecenoic acid, methyl ester, (E)- Fermentation of RPO with L. casei increases the components of chemical compounds contained therein. The stability of the RPO microencapsulated before fermentation provided an effective protection against oxidative damage to the oil and proved that the microencapsulation process can reduce the level of damage to the oil.

Abstract

Urinary tract infection (UTI) is one of the most common types of infection caused by the growth of microorganisms in the human urinary tract. Nitrite can be detected using spectroscopy, electrochemistry, chemiluminescence, chromatography, capillary electrophoresis, and flow injection analysis methods. However, this method takes quite a long time. So, this method is not suitable for rapid screening because it requires time for bacterial incubation and adequate sample preparation. So, there is a need for a fast-screening method that can diagnose UTIs through a nitrite colorimetric sensor. The colorimetric method is based on nanoparticles, which are relatively cheap and can provide visual and rapid detection. Nitrite is an indicator in diagnosing UTI. This research aims to determine the synthesis of Ag nanoparticles using avocado leaf bio-reductors (Persea americana Mill.) and chitosan as a stabilizer, which can be used as a colorimetric nitrite detector to minimize the use of dangerous and environmentally unfriendly inorganic materials. Characterization and analysis in this research used a UV-Vis spectrophotometer, FT-IR (Fourier Transform Infra-Red), and PSA (Particle Size Analyzer). The Ag nanoparticle synthesis process was carried out by varying the bioreductant volume, synthesis time, and chitosan concentration. It was found that the optimum synthesis time was 4 hours with an SPR value of 428 nm, an absorbance of 2.112 and a nanoparticle size. Apart from that, the optimum concentration of chitosan was obtained at a concentration of 2.5% with an SPR of 435 nm and an absorbance of 1.341 with a nanoparticle size. The results obtained from AgNPs/chitosan as a colorimetric nitrite detector showed a color change to purple with an LOD value of 0.1303 µM and an LOQ of 0.4345 µM. Keywords: Ag Nanoparticles; Avocado Leaveas; Colorimetry; Nitrite.

Abstract

General Background Environmental protection constitutes a fundamental obligation of the state encompassing constitutional, moral, and philosophical dimensions, particularly in safeguarding human rights to a good and healthy environment. Specific Background In Indonesia, environmental governance is formally supported by comprehensive legal frameworks; however, recurring environmental degradation indicates persistent challenges in implementation. Knowledge Gap There remains a critical gap between established legal norms and their practical enforcement, reflected in normative failure and law enforcement dysfunction. Aims This study aims to analyze the concept of state responsibility in environmental protection from a legal philosophy perspective and to examine the causes of normative failure and enforcement dysfunction in Indonesia. Results The findings reveal that state responsibility extends beyond formal rule-making to ensuring ecological justice, sustainability, and intergenerational protection, yet is undermined by regulatory disharmony, vague provisions, legal loopholes, and reactive, inconsistent enforcement practices, as illustrated by the tin commodity governance case. Novelty This study integrates legal philosophy with normative legal analysis to demonstrate that environmental protection failures stem from systemic weaknesses in legal substance, policy coherence, and enforcement structures. Implications The study underscores the necessity of regulatory harmonization, sustainability-oriented policymaking, and strengthened enforcement mechanisms to ensure effective, just, and sustainable environmental protection. Highlights: State obligations include ecological justice and intergenerational sustainability beyond formal regulation. Legal system weaknesses arise from regulatory inconsistency, unclear provisions, and structural loopholes. Enforcement practices remain reactive and selective, limiting prevention of environmental violations. Keywords: State Responsibility, Environmental Protection, Legal Philosophy, Normative Failure, Law Enforcement.
