Abstract

Standardization of Working Time at Cocoa Processing Unit, Rimbun Cooperative, Pidie JayaABSTRACT. Rimbun Cooperative is a business unit operating a chocolate factory producing several chocolate products such as cocoa fat, cocoa powder, 3 in 1 instant drinks (sachets), and chocolate bars. This research aims to measure standard times of operators in all working stations of the chocolate factory. These standards comprised the standards in roasting, peeling, pasting, pressing, powdering, powder sieving, powder mixing, dough mixing, refining, and chonching working stations. The data were directly collected using Time Study method with Stop Watch. The samples were randomly selected with five (5) repetitions; and the standard times were measured using Westinghouse Method to quantify performance and allowance factors. The result shows that standard times of operators in each working station are as follows: roasting (36 minutes), peeling (193 minutes), pasting (276 minutes), pressing (78 minutes), powdering (17 minutes), powder sieving (14 minutes), powder mixing (36 minutes), dough mixing (17 minutes), refining (30 minutes), and chonching (30 minutes). In peeling, pasting, powdering, powder sieving working stations, standard times of operators cannot be separated with working times of machines because the operators are required to run the machines (sequence). In general, standard times of operators, after calculation, are larger than direct records because during the working times, operators would not or could not use allowance factors for personal uses, such as for going to bathroom, drinking, and socializing with their colleagues as means to reduce stress or boredom.

Abstract

Open and Relational Theology, developed by Thomas Jay Oord, presents a controversial theological paradigm that emphasizes God’s openness and human free will as determinative factors for the future. This concept challenges traditional understandings of divine sovereignty and foreknowledge. This study aims to critically analyze the theological foundations of Open and Relational Theology, examine its implications for the doctrine of God’s sovereignty, and evaluate its consistency with biblical hermeneutics. Employing a qualitative approach, this research utilizes doctrinal analysis and comparative literature review. Primary data consists of Thomas Jay Oord’s works and related systematic theological literature, while secondary data includes theological journals and academic critiques of Open Theism. The findings reveal that Oord’s Open and Relational Theology constructs a mutual and interdependent God-human relationship, wherein divine foreknowledge is limited by human free will. This concept implies an indeterministic and probabilistic future, which stands in contrast to the doctrine of divine sovereignty in orthodox theology. Hermeneutical analysis uncovers inconsistencies with the biblical narrative of God's sovereign plan. Although Oord’s Open and Relational Theology offers a potential solution to the problem of theodicy, it fundamentally weakens the concept of divine sovereignty and introduces the risk of theological relativism in scriptural interpretation. Its practical implications may significantly alter the foundations of orthodox Christian faith.

Abstract

This study aims to analyze news texts about the 2024 Election published by the Tempo.co Instagram account through Norman Fairclough's critical discourse analysis approach. The research method used is descriptive qualitative, focusing on experiential, relational, and expressive value in the text displayed. Data were collected through reading and note-taking techniques, and the validity of the data was tested through triangulation. The study results show that experiential value is evident from frequently repeated ideological vocabulary, metaphors, and lexical terms that convey complex meanings. Relational value is seen through formal and informal words, which indicate the social relationship between political actors and the audience. Meanwhile, expressive value is reflected in the positive and negative evaluations used in the text, describing the social and political identity of the figures reported. Through the process of text production and consumption, news on Tempo.co Instagram is interpreted differently by the audience, allowing for the formation of various perspectives in understanding current political issues. This study shows how election discourse on social media can create critical interpretations in society and shape public opinion.

Abstract

The Polbeng Research Vessel is a ship that will be built by Politeknik Negeri Bengkalis (Polbeng) in collaboration with CV. Fatih Bahari Engineering. This vessel is made of High Density Polythene (HDPE) plastic, with the main dimensions of the ship: length (LOA) is 9 metres, breadth (B) is 2.2 metres, height (H) is 1.2 metres, and it uses an 85 HP outboat engine. This vessel's comfort study was conducted to see the ship's performance against equipment and humans in supporting research activities carried out by Polbeng. There are 4 cases in the study where there are 2 wave heights, namely 0.2 metres and 0.4 metres; each wave height is taken from 2 directions of waves hitting the ship, namely the beam seas direction (900) and the head seas direction (1800). There are 3 motions analysed, namely heave, roll, and pitch movements. The results of the ship's motion show that the roll motion in the Beam Seas wave direction has a more significant motion when compared to other motions. The analysis results show that the motion is in accordance with the theory that small ships for roll motions have shorter turnaround arms. Overall, this ship's motion is still common and meets the ship's comfort criteria based on the criteria issued by NORDFORSK 1987, STANAG 4154, U.S. Coast Guard (USCG), ISO 2631/1, ISO 2631/3, and BS. 6841:1987

Abstract

Penelitian ini bertujuan untuk menganalisis representasi tiga tahap perkembangan pemikiran masyarakat Indonesia menurut teori Auguste Comte, yakni tahap teologis, metafisik, dan positivistic dalam novel Bumi Manusia karya Pramoedya Ananta Toer. Jenis penelitian yang digunakan dalam penelitian ini ialah kualitatif deskriptif-analitis. Sumber data utama berupa teks novel Bumi Manusia, sementara data pendukung berasal dari literatur terkait teori sosiologi sastra dan konteks sosial novel. Data dikumpulkan melalui teknik baca dan catat, kemudian dianalisis menggunakan metode analisis isi yang berfokus pada pengelompokan dan interpretasi data sesuai teori yang digunakan. Hasil penelitian menunjukkan bahwa tahap teologis tercermin dalam narasi yang menggambarkan keyakinan terhadap kekuatan supranatural, seperti pandangan terhadap Annelies sebagai "kekasih para dewa." Tahap metafisik terlihat dalam refleksi filosofis terkait status sosial dan moralitas, seperti kritik terhadap budaya patriarki kolonial yang merendahkan perempuan pribumi. Tahap positivistik tergambar dalam penghargaan terhadap ilmu pengetahuan, pendidikan, dan rasionalitas modern, seperti dalam pengakuan Minke terhadap pentingnya teknologi cetak. Penelitian ini berkontribusi pada kajian sosiologi sastra dengan menawarkan perspektif evolusi pemikiran masyarakat yang tercermin dalam Bumi Manusia. Implikasinya, pembaca dapat memahami novel Bumi Manusia sebagai cerminan perubahan sosial dan intelektual, sekaligus memperoleh wawasan tentang relevansi sejarah pemikiran tersebut terhadap kondisi masyarakat kontemporer.
