The Effect of Rice Husk Volume Fraction on the Mechanical Properties of Composites
Full text linkRice husk waste is an abundant byproduct in Indonesia, but its utilization is still limited to conventional applications with low economic value. This study aims to utilize rice husk waste as a composite material with an epoxy resin matrix and to evaluate its mechanical properties through tensile and impact tests. The volume fraction variations of fibers used are 60%, 70%, and 80%, with the fabrication method employing the hand-lay-up technique. The tensile test results show that the composite strength increases with the fiber volume fraction, with the highest tensile strength value of 1.76 MPa at a 80% fiber fraction and the lowest value of 0.91 MPa at a 70% fiber fraction. Conversely, the impact test results show the highest impact value of 1.24 J at a 70% fiber fraction, while the lowest values are observed at 60% and 80% fiber fractions, both at 1.14 J. These findings indicate that the balance between fiber and matrix significantly influences the composite\u27s mechanical properties. This study concludes that rice husk waste has great potential as an environmentally friendly composite material with competitive mechanical properties. This utilization could serve as an innovative solution to reduce agricultural waste while enhancing its added value
Successful breeding of striped snakehead (Channa striata) using artificial methods with stripping techniques in the Ciparanje inland fisheries area laboratory
Full text linkChanna striata, or striped snakehead fish, is a freshwater fish with high economic value that is much needed by the community. The high demand for striped snakeheads still depends on the results of capture in nature. The high intensity of capture causes the availability of striped snakehead to be increasingly limited, but the cultivation of striped snakehead has not developed much in Indonesia. To anticipate these problems, this research aims to create striped snakehead cultivation techniques using artificial spawning methods with stripping techniques. The method used an experimental method with primary data obtained from direct observation and secondary data obtained from literature studies. The parameters observed were fecundity, FR (Fertilisation Rate), HR (Hatching Rate), and SR (Survival Rate). Fecundity results obtained from female striped snakehead were 1,578 grains, fertilization rate (FR) 88%, hatching rate (HR) 70.42%, and survival rate (SR) at the age of 7 days 94%. The results of the research show that snakehead fish (Channa striata) can be artificially spawned using a stripping technique using the GnRH (Gonadotropin Releasing Hormone) hormone which is useful for speeding up the ovulation process at a dose of 0.8 ml/kg for females and 0.6 ml/kg for males.

Full text linkPalm Oil Mill is a palm oil processing company that faces various challenges within its Crude Palm Oil (CPO) production flow. In this production flow, several types of waste hinder the efficiency and effectiveness of the value stream. Lean Manufacturing is a systematic approach aimed at improving production system efficiency by reducing or eliminating non-value-adding activities through continuous improvement efforts. Waste is defined as any activity that consumes resources but does not add value to the final product. Meanwhile, Value Stream Mapping is a mapping technique used to identify the flow of materials and information throughout the production process, starting from raw materials to finished products. This study was conducted to identify and minimize waste in the Crude Palm Oil (CPO) production flow. Based on the analysis results, waiting time was identified as a source of waste within the CPO production process. By implementing improvements through Current Value Stream Mapping analysis, the Process Cycle Efficiency (PCE) reached 61.09%. After further improvements by reducing non-value-adding time in the Future Value Stream Mapping, the PCE increased by 4.41% to 65.23%. Additionally, Process Activity Mapping also achieved time reduction, lowering the production lead time from 619.72 minutes to 580.33 minutes, resulting in a decrease of 39.39 minutes
Pemanfaatan Bakteri Halotoleran Untuk Meningkatkan Toleransi Padi Terhadap Cekaman Salinitas: Review
Full text linkSalinitas merupakan salah satu masalah global utama yang mengancam keberlanjutan pertanian, dengan lebih dari 20% lahan irigasi dunia terdampak dan diprediksi meningkat akibat perubahan iklim, intrusi air laut, serta praktik pengelolaan lahan yang kurang tepat. Secara regional, dampak salinisasi sangat terasa di wilayah pesisir Asia, termasuk Indonesia, di mana padi sebagai komoditas pangan utama mengalami penurunan produktivitas yang signifikan. Berbagai pendekatan konvensional seperti perbaikan irigasi, pencucian garam, dan penggunaan varietas toleran masih memiliki keterbatasan biaya dan efektivitas jangka panjang. Oleh karena itu, solusi alternatif yang ramah lingkungan semakin mendesak untuk dikaji dan diimplementasikan. Salah satu pendekatan yang menjanjikan adalah pemanfaatan bakteri halotoleran sebagai bio-inokulan. Artikel ini merupakan kajian literatur sistematis terhadap 67 publikasi ilmiah internasional (2016–2025) yang diperoleh dari basis data Google Scholar dan Scopus (Q1–Q4), menggunakan kata kunci bioinoculant; halotolerant-bacteria; rice; salinity-stress. Hasil telaah menunjukkan bahwa bakteri halotoleran seperti Bacillus, Pseudomonas, dan Halomonas dapat meningkatkan ketersediaan hara, merangsang produksi fitohormon, mengaktifkan enzim antioksidan, memperbaiki struktur tanah, serta menurunkan akumulasi ion toksik Na⁺ dan Cl⁻. Temuan ini menegaskan urgensi pemanfaatan bakteri halotoleran sebagai strategi bioteknologi yang berkelanjutan untuk meningkatkan toleransi padi terhadap cekaman salinitas. Implikasinya, penggunaan bio-inokulan halotoleran tidak hanya mendukung ketahanan pangan nasional di daerah pesisir tetapi juga berkontribusi pada pencapaian agenda pertanian berkelanjutan secara global

POWER RELATIONS AND PUBLIC CONTESTATION: AN ANALYSIS OF GOVERNOR DEDI MULYADI\u27S "MILITARY BARACKS" POLICY
Full text linkThis study aims to analyses the "military barracks" policy initiated by the Governor of West Java, Dedi Mulyadi as a response to juvenile delinquency as well as a complex product of power. The analytical framework uses the three-dimensional theory of power by Lukes and the sources of power by Mann to explain the political, military, and ideological interactions in public policy formation. The research method is a single case study with a Qualitative Content Analysis (QCA) approach. The data comes from the 12 most accessed national news and is strengthened by secondary data from the Indonesian Political Indicators survey (2025) regarding the level of public acceptance of this policy. The analysis is carried out through pre-processing of the text, identification of actors and concepts, the construction of discourse networks, and the calculation of network metrics to map the centre of power and framing of discourse. The results of the study show that the military barracks policy is an arena for the articulation of social forces that interact with each other. The program emphasizes how formal and symbolic power synergize to build legitimacy, while still provoking public debate about children\u27s rights and the effectiveness of militaristic approaches. This study also found that the military barracks policy is a concrete example of how power is interpreted, exercised, and debated. This policy represents the dynamics of democracy at the regional level. Policy is not only a product of the executive branch, but an interaction between political, military, media, public and legislative actors who mutually test the limits of power
