ANALISIS TEKANAN HIDROLIK TERHADAP OIL LOSSES PADA MESIN PRESS KAPASITAS 15 TON
Get PDFIn palm oil processing, there are five main stages: sterilization, threshing, digestion, pressing, and clarification. Among these, the pressing stage is one of the most critical. The pressing machine is used to separate crude oil from the fibers in the fruit pulp. This machine includes a pressing component, commonly referred to as the cone cage, which is operated by a hydraulic mechanism. The palm oil pressing process plays a crucial role in determining the success of processing fresh fruit bunches (FFB), as significant oil losses often occur during this stage. One of the key factors affecting these losses is the value of the hydraulic pressure. This study aims to investigate the effect of hydraulic pressure on oil losses in fibers for each pressing machine and to understand how the pressing machine operates. To analyze the hydraulic pressure variable and oil losses in fibers, observations were conducted by monitoring the pressure gauge on each pressing machine. The oil losses in fibers were measured through laboratory testing at the factory. The collected data were then compared. The results of this study indicate that hydraulic pressure has a significant effect on oil losses in the fibers of the pressing machine. At a hydraulic pressure of 49 bar, the smallest oil loss was recorded at 3.28%, whereas at a hydraulic pressure of 40 bar, the highest oil loss was observed at 4.42%. This demonstrates that higher hydraulic pressure results in lower oil losses, and vice versa.Dalam proses produksi pengolahan kelapa sawit terdiri dari lima proses sterilizer, Tresher, Digester, Pressing, dan klarifikasi. Dalam proses pengolah ini proses pressing merupakan salah satu yang paling penting. Mesin press merupakan mesin yang digunakan untuk memisahkan minyak kasar dari serat-serat dalam daging buah dan pada mesin press juga mempunyai komponen penekan atau biasa disebut dengan cone cage yang digerakan oleh mekanisme hidrolik. Proses pengepressan minyak kelapa sawit merupakan salah satu bagian penting yang menjadi faktor standart keberhasilan dalam pengolahan tandan buah segar (TBS) karena di dalam proses ini lah banyak kehilangan hasil minyak dan salah satu faktornya adalah nilai dari tekanan hidrolik. Penelitian ini bertujuan untuk mengetahui pengaruh nilai tekanan hidrolik terhadap oil losses in fiber pada setiap mesin press dan juga mengetahui bagaimana cara mesin press tersebut bekerja. Untuk mengetahui variable dari tekanan hidrolik dan nilai oil losses in fiber dilakukan dengan metologi pengamatan yaitu dengan mengamati preasure gauge pada setiapa mesin press dan untuk untuk oil losses in fiber dilakukan dengan pengujian pada lab pabrik. Dengan data tersebut maka akan dibandingkan antara dua data tersebut. Hasil dari penelitian ini adalah tekanan hidrolik berpengaruh signifikan terhadap nilai oil losses pada serat dalam mesin press. Dengan tekanan hidrolik 49 bar diperoleh oil losses terkecil sebesar 3,28%, sementara pada tekanan hidrolik 40 bar diperoleh oil losses tertinggi yaitu 4,42% . Hal ini menunjukkan bahwa semakin tinggi tekanan hidrolik, semakin kecil nilai oil losses yang terjadi, dan sebaliknya

INTEGRATION OF PHILOSOPHY OF SCIENCE IN THE REFORM OF NOTARY LAW IN THE DIGITAL AGE
Get PDFThe development of digital technology has driven fundamental changes in notarial practices, which were previously conventional, relying on physical documents and the direct presence of notaries. However, the existing regulation, Law No. 2/2014 on Notary Position, has not comprehensively accommodated this digital transformation. This research aims to analyze the importance of the integration of philosophy of science in the reform of notarial law, so as not only to adjust the technical aspects, but also to uphold the basic values of law. This research uses a literature study method with a juridical-normative and philosophical approach. The study was conducted by reviewing legal documents, theories, and the results of previous research. The results show that the integration of philosophy of science through epistemology, ontology, and axiology approaches is able to provide a strong conceptual basis for the renewal of digital notarial law. The epistemology aspect highlights the importance of scientific verification of electronic deeds, ontology demands legal recognition of the existence of digital documents, while axiology emphasizes justice, professional ethics, and social usefulness. With the integration of the three branches of philosophy of science, it is hoped that legal policies will be created that are not only responsive to technological developments, but also based on the basic principles of the notary profession: legal certainty, expediency, and protection of the interests of the wider community. With this framework, the reform of notary law can run effectively and sustainably, not merely as a response to technological trends, but as a form of commitment to a fair, valid, and responsive legal system.

Vegetable as Rabbit Feed: between Benefits and Health Risks: Sayuran sebagai Pakan Kelinci: antara Manfaat dan Risiko terhadap Kesehatan
No full textThis review aims to explore the benefits and risks of using vegetables as rabbit feed. The study was conducted using a literature review method, examining various scientific sources including journal articles, e-books, and other relevant literature related to the selected topic. Based on the findings of the review, vegetables can serve as a supplementary feed due to their rich content of nutrients such as amino acids, vitamins, minerals, and antioxidants that support rabbit health. Several types of vegetables such as water spinach, carrot leaves, carrots, and sweet potato leaves have been shown to improve feed intake and rabbit growth when given in appropriate proportions. Feeding vegetables can provide dietary variety, offer additional fiber, and serve as a cost-effective feed alternative. However, excessive vegetable intake poses several health risks, including digestive disturbances, diarrhea, bloating, impaired nutrient absorption, and potential toxicity due to the presence of anti-nutritional factors such as tannins, oxalates, phytates, and other compounds. In addition, pesticide contamination and residues may negatively affect rabbit health. Therefore, proper feeding strategies are necessary, such as ensuring vegetables are free from contaminants, wilting them before feeding, and regulating the quantity to avoid replacing primary fiber sources like grass or hay. A recommended inclusion rate of vegetables is 8–10% of the total daily diet. With proper feed management, vegetables can be a valuable alternative to support rabbit growth and health without causing adverse effects. This review provides insight into the potential benefits and risks of vegetable use as rabbit feed, along with appropriate recommendations to help achieve optimal daily nutritional balanc

Implementation of The Pentahelix Model on Empowering Family Welfare (PKK) in Malabero Village
Get PDFCommunity empowerment is a strategic effort to improve economic welfare, especially for the Family Welfare Empowerment (PKK) women group. This research examines the implementation of the Pentahelix model in training on processing seafood into dim sum made from mackerel in Malabero Village, Bengkulu City. The Pentahelix model approach involves synergy between government, academics, communities, business people, and the media in supporting sustainable community empowerment. The method used in this research is descriptive qualitative with observation, interview, and documentation techniques. The research results show that this training increases the skills and insight of PKK women in processing marine products into products of high economic value. In addition, the Pentahelix model has proven effective in strengthening collaboration between stakeholders, supporting product marketing via social media, and opening up culinary-based business opportunities. Through training programs, people not only gain new skills but also have the opportunity to improve their welfare through creative food-based businesses. However, program sustainability is still a challenge that requires long-term strengthening and mentoring strategies. This research recommends the need for more adaptive policies and sustainable support so that empowerment based on local potential can provide a more significant economic impact.
