Physical properties of sawdust (i.e. particle size distribution, particle density, porosity, and water retention) from five tropical commercial wood species (Shorealeprosula, Dryobalanops lanceolata, Dipterocarpus cornutus, Shorea laevis, and Eusideroxylon zwageri) Â as prepared in various mill types (i.e. handsaw, sawmill, and milling ) were analyzed. This study aims to look into the relationship and interconnected between the use of different mill types, density of wood species origin and physical properties of the resulting sawdust. Generally, different mill types produced sawdust with different particle size distributions. The use of a handsaw produced a higher proportion of oversized particles (OS) and coarser particle size (CPS) than that of sawmill and milling , while also commonly producing the lowest proportion of fine particle size (FPS). For each wood species, the proportion of OS was lower than that of CPS and FPS. In addition, particle density and water retention produced by handsaw in CPS as well as FPS was the smallest, followed in an increasing order sawmill and milling. Porosity of CPS and FPS was the highest in handsaw-cut sawdust, followed in a decreasing order sawmill and milling cut sawdust. This study showed that the different mill types and particle size influenced the physical properties of sawdust. Further, analysis of influential factors on porosity and water retention using General Linear Model revealed that particle density inflicted a strong influence on porosity, as did particle size on water retention.

This study discusses the role of women in the legislature, especially in the Regional House of Representatives of Province. Women in Indonesia are formally strong enough because there are many provisions in various laws and other regulations that provide juridical protection for women. The representation of women in the dissertation legislature is actively involved in the legislative decision-making process, budgeting and supervision will produce gender-responsive government and development policies as strategic instruments to realize gender justice and equality in various aspects of development. However, the role of women as members of the legislature is still undervalued, including members of the legislature in the Regional House of Representatives of Province. In this case, analyze the problem by using an institutional approach. The institutional approach is one that explains what should be, not what it really is. The main idea of institutional theory is that organizations are shaped by the institutional environment that surrounds them. There are four concepts from the institutionalism approach, namely Categorical Adjustments, Structural Adjustments, Procedural Adjustments and Personnel Adjustments.

This study discusses the description of women's representation in the realm of political politics by paying attention to the perspective of regulation and implementation. The study focused on women's political rights, all of which stated that women have the same political rights as men. By using qualitative research methods. This study concludes that women's representation in the political system has a very important role to create a gender-just political system because if women's representation is replaced by men, the mechanism in gender justice will turn into a gender bias where women are still applied unfairly and this can also be said to be a partial and detrimental condition. the representation of women in politics is a manifestation of the fulfillment of citizenship rights, namely the right granted by the state to a citizen or community to have the right to participate in the political field whose mechanism has been regulated in legislation.

Depression represents a manifestation of prolonged stress, which, if left untreated, may lead to severe mental disorders. For depression treatment therapy, it can be carried out based on evidence-based treatment for depression and anxiety. Aromatherapy candles can be used as a non-pharmacological medium for depression therapy, where keruing has active compounds are phthalic acid di(3-methoxybenzyl) ester and phthalic acid, 5-ethyl-1,3-dioxan-5-yl octyl ester, causing keruing oleoresin to have a distinctive fragrance. This study aims to evaluate the pharmacological potential of keruing as an antidepressant for non-pharmacological therapy. Aromatherapy candles were formulated with keruing oleoresin at concentrations of 0%, 2.5%, 5%, 7.5%, and 10%, followed by testing their antidepressant activity using the Conditioned Place Preference (CPP) method. The results of the Paired T-test for groups F0, F2, and F4 or formulas containing 0%, 5%, and 10% of keruing oleoresin have a significant effect (sig. values <0.05) between pre and post-test being given aromatherapy and induction. In the One-way ANOVA test, between their groups, it can be seen there was no significant difference in test activity, namely for the pre-treatment test (sig. 0.445 > 0.05) and for the post-treatment test (sig. 0.065 > 0.05). Results indicated that while the candles met physical quality standards outlined by the Indonesian National Standard (SNI), no significant antidepressant effects were observed in mice. Further refinement in methodology, including the concentration of active compounds and delivery methods, is recommended to enhance the pharmacological potential of keruing oleoresin.

Hypertensive is a cardiovascular system disorder characterized by systolic pressure ≥ 140mmHg and diastolic ≥ 90mmHg. The increase in blod pressure is due to the mechanism of angiotensin II and β-adrenergic receptors, so in developing medicine for hypertension, compounds are needed to inhibit the activation of angiotensin II to angiotensin II, as well as β-adrenergic. Kalimantan, Indonesia has a biodiversity that has the potential as medicine such as Bangkirai (Shorea laevis Ridl.). Based on previous research on secondary metabolites, various compounds have been identified that have potential as new drug candidates, for example as antihypertensive. This study aims to determine the pharmacological profile and mechanism of angiotensin I inhibition at the 4ZUD and β-adrenergic receptors inhibition at the 6PS5 receptor, from ethanol extract of bangkirai leaves by carrying out molecular docking which begins with several stages including preparation and optimization of the structure of the test compound and structure preparation of 3D receptors 4ZUD and 6PS5. To find out the correctness of the method, validation was carried out on the Olmesartan ligand compound for 4ZUD and the propranolol ligand for 6PS5. Based on research carried out on both receptors, results were obtained for the test compounds in the form of MolDockScore, the pharmacological profile of absorption, distribution, metabolism, excretion, and toxicity. MolDockScore results show that the compound Colchicine, N-desacetyl-N-[4-hydroxy-3,5-dimethoxycinnamoyl] has the lowest values, namely -146.503 at the 4ZUD receptor dan -129.718 at the 6PS5 receptor, which is close to the natural ligand value compared to other metabolite compounds. Apart from that, it also provides good results based on the pharmacological profile of the 4ZUD and 6PS5 receptors including HIA (95.73%), Caco2 (35.14nm/second), and PPB (87.67%). Negative test results are also shown in the mutagenic toxicity profile (Ames Test Method), non-mutagenic, and carcinogenic tests which include genotoxic and nongenotoxic.

Aktivitas pertambangan batubara dengan sistem terbuka di Indonesia, termasuk di areal PT Indominco Mandiri (PT IMM), selain mendatangkan dampak positif dari segi ekonomi, tak pelak juga mendatangkan dampak negatif terutama terhadap lingkungan. Perubahan lingkungan yang paling mengkhawatirkan berkaitan dengan perubahan bentang lahan dan keseimbangan ekosistem permukaan tanah, termasuk kerusakan terhadap kualitas tanah. Penelitan ini bertujuan untuk mengetahui pengaruh kegiatan revegetasi terhadap status kesuburan tanah di areal reklamasi dan pascatambang PT IMM. Pengumpulan data dilakukan sebanyak dua kali pengamatan di tahun 2022 dan 2024. Analisa kesuburan tanah dilakukan terhadap beberapa sampel tanah yang terdiri dari tanah tidak terusik untuk uji sifat fisik dan tanah komposit untuk uji sifat kimia tanah yang disertai dengan pengamatan lapangan. Berdasarkan hasil pengamatan dan analisa kesuburan tanah yang dilakukan pada tahun pengamatan 2022 dan 2024, tingkat kesuburan tanah di areal PT IMM termasuk dalam kategori rendah. Rendahnya status kesuburan tanah tersebut, diperkirakan bukan hanya akibat dari kegiatan pertambangan batubara yang dilakukan, melainkan juga merupakan kondisi kesuburan pada rona awal tanah yang memang tergolong rendah. Meskipun demikian, jika dilihat dari hasil analisa kimia tanahnya, secara umum ada beberapa sifat tanah yang nilai indikator kesuburannya mengalami perbaikan dari tahun 2022 ke tahun pengamatan 2024. Hal ini mengisyaratkan bahwa program revegetasi yang dilakukan oleh PT IMM secara perlahan dapat memperbaiki kualitas tanah di areal sekitar.
