PENGARUH KEMASAN TERHADAP KARAKTERISTIK FRAKSI GULA BUAH NAGA MERAH (Hylocereus polyrhizus) DAN BUAH NAGA PUTIH (Hylocereus undatus) SELAMA PENYIMPANAN DINGIN: A Study on Quality Retention under Different Packaging Types
No full textDragon fruit is classified as a non-climacteric fruit, so to obtain the best quality, harvesting and storage conditions must be optimized. The aim of this experiment was to determine the effect of packaging using Low-Density Polyethylene (LDPE) plastic and paper during cold storage on the sugar fractions of fructose, glucose, and sucrose in red dragon fruit (Hylocereus polyrhizus) and white dragon fruit (Hylocereus undatus). The experiment was conducted using a Completely Randomized Design (CRD) with four replications and involved two factors. The first factor was packaging (no packaging, plastic packaging, and paper packaging), and the second factor was storage temperature at 15°C. Sugar fraction characterization was done using High-Performance Liquid Chromatography (HPLC). The results showed that paper packaging was the best packaging method to maintain the sugar fractions, particularly fructose and glucose, in both red and white dragon fruit until day 21 of storage compared to no packaging. The fructose content in red dragon fruit with paper packaging was 46% higher, while glucose content did not show significant differences. An increase in both fructose and glucose content also occurred in white dragon fruit with paper packaging, with a 28% increase in fructose and a 17% increase in glucose
Komunikasi Transendental Usif Boti dalam Ritual Halaika dan Pembentukan Harmoni Komunitas
Get PDFABSTRACT
The Boti Dalam indigenous community in South Central Timor Regency, East Nusa Tenggara Province, continues to uphold the traditional Halaika belief system, which positions the Usif (king) Boti as both the spiritual leader and the guardian of social order. The study aims to explore the forms and meanings of the Usif Boti’s transcendental communication within Halaika rituals and to examine its contribution to maintaining social order and community harmony. The research adopts a constructivist paradigm with an ethnographic approach, and the data were collected through participant observation and in-depth interviews with the Boti King, community leaders, and members of the Boti Dalam community. The findings show that the Usif Boti’s transcendental communication is expressed through prayers and decrees addressed to Uis Neno (the sky deity) and Uis Pah (the earth deity) across various stages of life, particularly within the agricultural cycle. This form of communication is regarded as a sacred invocation that carries spiritual and moral legitimacy, and is therefore followed by all members of the Boti Dalam community. Through rituals such as onen (prayer), including the ninth-day observance (neon leuf) and the harvest thanksgiving (poi pah), the Usif Boti’s transcendental communication functions as a symbolic force that unites the community, sustains social order, and reinforces the value of fraternal love (lais manekat). The study concludes that the transcendental communication of the Usif Boti plays a central role as a symbolic instrument that supports social and economic harmony and order within the Boti Dalam community.

Tujuan penelitian antara lain mengeksplorasi bentuk dan pemaknaan komunikasi transendental Usif Boti dalam ritual Halaika, serta menelaah kontribusinya dalam membangun keteraturan sosial dan harmoni komunitas. Paradigma penelitian yang digunakan adalah konstruktivistik dengan pendekatan etnografi, dan data dihimpun melalui observasi partisipan serta wawancara mendalam dengan Raja Boti, tokoh masyarakat, serta warga Boti Dalam. Hasil kajian menunjukkan bahwa komunikasi transendental Usif Boti terwujud melalui doa dan titah yang dipersembahkan kepada Uis Neno (dewa langit) dan Uis Pah (dewa bumi) dalam berbagai tahapan kehidupan, khususnya dalam siklus pertanian. Komunikasi transendental Usif Boti dikonstruksi sebagai doa sakral yang mengandung legitimasi spiritual dan moral, sehingga ditaati oleh seluruh warga masyarakat Boti Dalam. Melalui ritual seperti onen (sembahyang) baik pada momentum hari kesembilan (neon leuf), maupun syukuran panen (poi pah), komunikasi transendental Usif Boti berfungsi sebagai simbol yang mengikat komunitas, menjaga keteraturan sosial, serta meneguhkan nilai kasih persaudaraan (lais manekat). Penelitian ini menyimpulkan bahwa komunikasi transendental Usif Boti memiliki peran sentral sebagai instrumen simbolik yang dapat menopang harmoni dan keteraturan sosial dan ekonomi dalam masyarakat Boti Dalam
Analisis Resepsi Jurnalis Terkait Berita Pemidanaan Direktur JAKTV dengan Pasal Perintangan Penyidikan
Get PDFABSTRACT
In early 2025, news broke that JAKTV News Director Tian Bahtiar was implicated in a crude palm oil corruption case, sparking public and journalistic debate. This study describes and analyzes journalists’ responses to his indictment under obstruction of justice, using Stuart Hall's Encoding-Decoding Theory. The theory suggests that media messages are encoded by producers and interpreted differently by audiences. Through qualitative reception analysis, the study identifies three audience positions: dominant hegemonic, negotiated, and oppositional. Results show that journalists responded in varied ways—some aligned with the Attorney General's narrative, some negotiated it with ethical considerations, and others rejected it. These differences are shaped by factors like journalistic background, experience, and ethical integrity. The study highlights the dynamic relationship between media, law, and journalistic ethics, stressing the need to strengthen journalistic independence in the face of ethical challenges.

GREEN ACCOUNTING IN PRACTICE: COMPARATIVE COST ANALYSIS OF MANAGEMENT AT A KUPANG HOSPITAL
Get PDFResearch Purposes. This study evaluates the comparative costs of using incinerators and third-party services in medical waste management at Hospital X.
Research Methods The research employs a qualitative approach through interviews, observations, and document analysis.
Research Results and Findings The findings reveal that since the incinerator malfunctioned in 2020, Hospital X has lost up to IDR 22.5 billion in revenue over five years and has incurred costs ranging from IDR 359.6 million to IDR 539.4 million for third-party services. Without an operational incinerator, waste management costs have increased, and revenue losses have persisted. Therefore, investment in repairing or procuring an incinerator is recommended to enhance waste management efficiency and ensure the hospital's financial sustainability. The implications of these findings reveal that dependence on third-party waste management leads to substantial cost burdens and long-term revenue loss. A strategic implication is the need for hospitals to reinvest in incinerator facilities to enhance cost efficiency, support sustainable waste policies, and ensure regulatory compliance

Analysis of T5 Heat Treatment Parameters on the Hardness and Microstructure of Aluminum-Silicon Alloy
Get PDFIn alignment with the United Nations Sustainable Development Goal (SDG) 9 on Industry, Innovation, and Infrastructure, this study investigates methods to enhance the durability and sustainability of aluminum alloys in automotive applications, thereby reducing material waste and extending component life. Aluminum is widely used in automotive parts like engine pistons due to its beneficial properties, including lightweight, high formability, and excellent corrosion resistance. A key material in these applications is the Aluminum-Silicon (AlSi) alloy, which is known for its mechanical strength but also prone to gradual performance degradation under operational stress. Addressing this challenge, T5 heat treatment is applied to explore its impact on the alloy's microstructure and hardness, with the aim of enhancing resilience and extending the functional lifespan of automotive parts. The T5 heat treatment process involves three main stages: initial heating, sustained heating, and cooling. By exposing the AlSi alloy to varied temperatures of 240°C, 260°C, and 280°C, with a holding time of 30 minutes, this study evaluates how these temperature conditions influence the alloy's mechanical properties. The findings from Rockwell hardness testing reveal that at 240°C in SAE 40 oil at 750°C, the alloy reaches a hardness of 64.6 HRB. Similarly, at 260°C in air at room temperature, the hardness remains at 64.6 HRB, while at 280°C in water with a pH of 8 at 750°C, the hardness slightly decreases to 62.1 HRB. These results suggest that higher heating temperatures improve mechanical strength and significantly alter the microstructure of the AlSi alloy, with minor variations in hardness observed depending on cooling mediums. This study demonstrates that optimizing heat treatment can enhance both the mechanical properties and durability of AlSi alloys, contributing to the production of more resilient and sustainable automotive components in line with SDG 9 objectives
