Abstract

This research aimed to investigate the influence of three types of palm oil products (RBDPO (refined bleached deodorized palm oi), RPO (red palm oil), and PKO (palm kernel oil)), on serum glucose and lipid profile of Sprague Dawley rats fed with experimental diet containing 20% of oils, comparing these effects with those of with animal- base oil (beef tallow) including corn oil as a representative from vegetable oil. The diet with level of fat 20% given to two groups (with and without AOM (azoxymethane)) of male Sprague Dawley rats for 13 weeks. The results exhibit that corn oil caused the lowest value of serum glucose (p < 0.05) in both AOM and non-AOM groups. Compared to other groups, beef tallow diet significantly increased serum triglycerides, cholesterol, and LDL, followed by RPO/PKO, RBDPO, and corn oil, respectively (p < 0.05). Meanwhile, corn oil diet produced the highest level of serum HDL, followed by RBDPO, PKO/RPO, and beef tallow (p < 0.05).

Abstract

The amount of fatty acids added is critical in creating starch-lipid complexes, which can affect their formation and properties. To use the complex to stabilize oil-in-water emulsion systems, this study intends to assess the effects of fatty acid concentrations on the effectiveness of starch-lipid complex formation and the properties of the resulting complexes. Ultrasonication was used to produce starch-lipid complexes from sago starch with different fatty acid contents (10, 12.5, 15, 17.5, and 20%) for the study. The results demonstrated that adding fatty acids up to 15% concentration significantly improved the water absorption capacity (WAC). In contrast, increasing the complexing index (CI), relative crystallinity (RC), oil absorption capacity (OAC), and contact angle of sago starch-lipid complexes. When the concentration of fatty acids was raised over 15%, the properties of the starch-lipid complex did not change considerably. A concentration of 15% with CI 67.07%, RC 37.94%, WAC 1.352 mL/g, OAC 1.370 mL/g, contact angle 70.82 °, emulsion capacity 36.72%, and emulsion stability 35.80% was shown to be the optimal amount of fatty acids for the production of sago starch-lipid complex. Emulsion stability and capacity can be maintained using a sago starch-lipid complex with an ideal fatty acid concentration of 15%.

Abstract

Isoflavon merupakan kelompok senyawa isoflavonoid dengan fungsi fisiologis yang bermanfaat bagi tubuh manusia. Bioaktivitas fisiologis isoflavon berasal dari potensinya sebagai antioksidan dan fungsinya yang bermanfaat bagi kesehatan seperti antikanker, antidiabetes, dan antiinflamasi. Isoflavon dalam bentuk tak terkonjugasi atau aglikon dianggap lebih aktif daripada bentuk glukosida. Sprouting merupakan salah satu metode pengolahan untuk meningkatkan bioavailabilitas isoflavon dengan mengubah isoflavon dari glukosida menjadi bentuk aglikon. Pada penelitian ini profil isoflavon dan aktivitas antioksidan yang dipengaruhi oleh perkecambahan selama 48 jam dilakukan pada bagian kecambah yaitu kotiledon (KTL) dan hipokotil (HPL). Hasil penelitian ini menunjukkan bahwa bagian hipokotil mengandung isoflavon aglikon lebih tinggi daripada bagian kotiledon, terutama daidzein. Aktivitas antioksidan dilakukan dengan metode scavenging radikal DPPH (1,1-diphenyl-2-picrylhydrazyl) untuk ekstrak bagian kecambah seperti kotiledon dan hipokotil. Hipokotil memiliki kapasitas antioksidan tertinggi (nilai IC50 1839,113 ppm), yang secara signifikan lebih baik dari kotiledon dan memiliki perbedaan yang signifikan (p<0,05). Perkecambahan meningkatkan aktivitas antioksidan dan kadar isoflavon yang lebih tinggi di hipokotil, terutama untuk isoflavon daidzein.

Abstract

The research explores the resolution of customary criminal disputes in the context of the Baduy tribe, an ethnic group in Banten Province, Indonesia, with a focus on harmonization between local customary law and national criminal law. Through normative juridical methodology and analytical descriptive analysis, this study explores the mechanisms for resolving customary criminal disputes and their relationship with national criminal law. The results reveal the challenges in achieving harmony between traditional values and modern criminal law principles, as well as the implications for legal justice and human rights. The statutory approach and case approach help to comprehensively describe these dynamics, provide in-depth insight into the interaction between Baduy tribal customary law and Indonesian national criminal law and highlight the need for improved policies that are more inclusive and just.
