The lathe is a machine tool used to cut cylindrical workpieces. On the lathe, the direction of tailstock movement follows the surface contour board machine guide ways. If there is uniformity flatness on the bottom of the machine, it will affect the precision of the lathe. The purpose of this study is to determine and evaluate the flatness deviation value in guide ways of lathes GDW LZ 350. The method used is to measure the guide ways on a lathe using a measuring instrument digi-pas DWL-200, to obtain a deviation value as a reference process leveling machine pedestal. Results obtained from this study is a guide ways flatness deviation average value of 0,1o, general flatness deviation occurs at both ends of the guide ways, the machine MB3 and MB4 flatness deviation occurs is not uniform between the guide way 1 and 2, it caused by the tilt position of guide ways. So loading guide ways only focused on one side only.Keywords : lathe, guide ways, flatness, pedestal

Abstrak--Penelitian ini bertujuan untuk memahami persepsi dan mispersepsi antarnegara pengaku kedaulatan di Laut Tiongkok Selatan, serta melihat peluang diplomasi pertahanan Indonesia. Dengan menggunakan metode penelitian kualitatif, penelitian ini memiliki dua bagian analisis utama. Bagian pertama berisikan analisis mengenai persepsi dan mispersepsi negara-negara yang memiliki klaim kedaulatan di wilayah maritime yang berpotensi bereskalasi menjadi konflik kekerasan. Untuk bagian pertama ini peneliti akan menggunakan pendekatan persepsi dan mispersepsi dalam politik internasional. Bagian kedua berisikan analisis mengenai peluang diplomasi pertahanan Indonesia untuk meredam mispersepsi antarnegara dan meningkatkan sikap saling percaya untuk mencegah eskalasi konflik di wilayah maritim ini. Untuk bagian kedua ini peneliti akan menggunakan pendekatan diplomasi pertahanan. Secara akademik dan empirik, Penelitian           ini akan berkontribusi memberikan alternative pemahaman dan masukan kebijakan terkait sengketa di Laut Tiongkok Selatan melalui analisis yang memiliki sandaran teoritik yang jelas (theory-informed analysis).Kata Kunci: Laut Tiongkok Selatan, persepsi, mispersepsi, diplomasi pertahanan Abstract--This study aims to understand the perception and misperception of the claimant states in the South China Sea disputes and examine the opportunities for Indonesia's defense diplomacy. Using qualitative method, this study proceeds with two main parts. The first part analyzes the prospect of conflict escalation caused by the perception and misperception among the claimant states in the South China Sea disputes. The authors employ perception and misperception approach in International Relations in the analysis. The second part of the study examines the opportunities for Indonesia's defense diplomacy in reducing the misperception, mitigating the confict escalation as well as increasing mutual trust and confidence among the conflicting parties. In this second part, the authors make use of "defense diplomacy" as the conceptual tool. This study is academically and empirically significant as it contributes by giving alternative understanding on the South China Sea disputes as well as research-based and theory-informed policy recommendation.Keywords: South China Sea, perception and misperception, defense diplomacy

The CO2 content in biogas is an impurity, so it needs to be reduced. One way to reduce the levels of CO2 in biogas is by purification with tile-zeolite adsorbents. The purpose of this study was to determine the use of tile - zeolite as an adsorbent in the purification process to reduce CO2Â levels using a 23 factorial design. The use of tile powder adsorbents (25% and 75%) - Zeolite (75% and 25%), biogas flow rates of 1 and 6 liters/minute, which were investigated at intervals of 5 and 20 minutes, to collect CO2 content data. Gas Chromatography-Mass Spectrometry (GCMS) is used to test the adsorption gas content. The results are shown by the Pareto curve resulting from biogas purification of CO2 levels, each of which has a magnitude of response to CO2 levels. Increased levels of tile-zeolite as an adsorbent and the rate of biogas flow in the purification process had an effect of reducing CO2 levels by 44.214%. Conversely, an increase in tile-zeolite levels as an adsorbent increases CO2 levels in the biogas purification process. Natural tile is a porous material that can adsorb and has ions that can be exchanged with ions from the outside.

This research is motivated by the problem of the lack of mathematics learning that uses examples of local culture, for example learning Transformation Geometry through the Tanah Liek batik motif in Minangkabau. As a result, students tend to feel bored because the activities carried out are monotonous just sitting, listening and copying. The aim of this research is to find out the topic of geometric transformation in the Tanah Liek batik culture in Minangkabau and to find out the use of the Tanah Liek batik context in Geometry Transformation learning. This type of research is qualitative with an ethnographic approach. Which uses data collection techniques through in-depth interviews, participant observation and documentation studies. Which is located at the Tanah Liek Batik House and Loempo Batik House. The theoretical basis for this research is the ethnomathematics of Minangkabau typical Tanah Liek batik on Geometry Transformation material for class XI SMA/MA. The results and discussion of this research relate the material of Geometric Transformation. Which is associated with the typical Minangkabau Tanah Liek batik pattern. In accordance with previous relevant research that ethnomathematics has a relationship with mathematics learning materials. Thus, this research can produce an initial study on the ethnomathematics of Minangkabau typical Tanah Liek batik on Geometry Transformation material for class XI SMA/MA.

Forensics is a science that has a crucial role in the judicial process through examination and collection of physical evidence found at crime scenes. The involvement of forensic experts at crime scenes usually occurs in significant cases, where they are only called upon request from the authorities. This study aims to study the role of forensic medicine in helping investigators find material truth in murder cases, as well as identify possible obstacles. Through a library legal research and descriptive approach, secondary data such as legal documents and literature are analyzed to provide a clear and detailed picture of role of forensic science in assisting investigators in finding the material truth in murder cases and asserting the obstacle of it. The results showed that forensic medicine has a crucial role in uncovering material truths and providing legitimate evidence in murder cases. However, lack of coordination between law enforcement officials and forensic doctors can be an obstacle. Therefore, good cooperation and coordination between law enforcement officials and forensic doctors is the key to success in handling this case. The principle of justice must be upheld in the investigation process.

This study investigates Confucius' views on education and their rel-evance in the 4.0 era. Confucius is known as "the great model teach-er for centuries" for his dedication to education and his thoughts regarding its role, purpose, substance, and teaching techniques. Con-fucius founded Confucianism. Confucius felt education should be a right for everyone, not just the affluent. "No class difference in school" quickly transforms people's educational views. It makes formal schooling possible for most individuals. The idea of Confu-cius is innovative because people from all backgrounds desire jus-tice and equality in education. However, a synthesis of Confucius' education concepts based on past research adds to the literature on educational philosophy. Confucius's thoughts help people world-wide understand the incredible education ideas that have ever de-veloped in moral education. The results of this research can be guid-ed and affect modern educational authorities and policymakers.
