PT Timah Tbk is a mining industry company which produces the tin metal. A mining former area which is chosen as the research location is Lahan Air Jelitik 3. This research aims to analyze the success of Lahan Air Jelitik 3’s reclamation based on Matrik 16 and Matrik 17 of Keputusan Menteri Energi Sumber Daya Mineral Nomor 1827 Tahun 2018. The research starts with collecting the primary data which consists of 43 and 29 coordinate points of Lahan Air Jelitik 3’s adjustment and revegetation, the length and width of 22 erosion in Blok 1, 24 erosion in Blok 2 and 4 landslide in both blocks, the height and diameter of 35 primary plants and the length of 5 cover crops. Those primary data and secondary data are processed by calculating the broad realization of Lahan Air Jelitik 3’s adjustment and revegetation, the amount of plants, the average of plant’s height and diameter, the stability of area and valuating the success of adjustment area, the success of revegetation, the success of last completion based on Matrik 16, also calculating the success reclamation value based on Matrik 17. The result of data processing shows the success value of adjustment and hoard area is 0.5, top soil’s spreading is 0.91, erosion and sedimentation’s control is 0, cover crop’s revegetation is 0.86, fast growing plant’s revegetation is 0.1765, local plant’s revegetation is 0.726, acid mine drainage’s management is 0, plant’s closure is 0.1059 and plant’s maintenance is 0.333. The reclamation’s success percentage 50.65% in Lahan Air Jelitik 3 PT Timah Tbk shows that the reclamation in that area is not good enough and the area needs improvement especially in plant’s maintenance, erosion and sedimentation’s control and acid mine drainage’s management.
Pengaruh Kecepatan Aliran dan Debit Aliran Terhadap Peningkatan Perolehan Konsentrat Bijih Timah Dalam Tailing Pada Alat Secondary Lobby Box Skala Laboratorium

Published: November 2022

Tailings are the result of the process of mining or processing mineral ore which is considered tohave no economic value. The g in the tailings as evidence that there are losses of cassiterite mineralsthat are also wasted is still of economic value. To reduce losses of cassiterite minerals in tailings, thetool used is the secondary lobby box. The washing of tin tailings was carried out 6 times including theflowrate and the speed of the water flow given differently affected by the opening of the water faucetthat forms the angle of partition on the secondary lobby box. Each of these angles is 15⁰, 30⁰, 45⁰ ,60⁰, 75⁰, and 90⁰. From each experiment a bait was used in the form of tailings with a weight of 5 kgeach (0.47% Sn). At faucet position 15⁰ flow rate of 20.5 l/minute and water flow rate of 0.017 m/secproduced 1.19% Sn and recovery at 76%, position 30⁰ flow rate of 23.5 l/minute and water flow rate of0.020 m/sec produced 1.22% Sn and recovery at 73%, position 45⁰ flow rate of 26 l/minute and waterflow rate of 0.022 m/sec produced 1.25% Sn and recovery at 68%, position 60⁰ flow rate of 28.7l/minute and water flow rate of 0.025 m/sec produced 1.28% Sn and recovery at 65%, position 75⁰flow rate of 32.6 l/minute and water flow rate of 0.028 m/sec produced 1.30% Sn and recovery at53%, and position 90⁰ flow rate of 41 l/min and water flow rate of 0.035 m/sec produced 2.26% Sn andrecovery at 50%. The highest concentration of 2.26% Sn and the desired recovery in the tailingsseparation process is the lowest recovery of 50% in the 90⁰ faucet position. This shows that theprocess of separating products in the form of tailings has increased significantly from the feed contentof 0.47% Sn to 2.26% Sn and transforming tailings products into economically valuable ores.
Technical Study of Blasting Geometry and Powder Factor of Fragmentation at Pit 3 Banko Barat PT Bukit Asam Tbk
Authors: Ramadhini Hermita , Irvani Irvani , Oktarianty Haslen
Published: November 2022

Mining PT Bukit Asam Tbk is one of the company that works in coal mining. One of the demolition activities in PT Bukit Asam Tbk is overburden stripping using drilling method and blasting. The success rate of blasting activity can be seen from the fragmentation as the blasting result, where the material size is equally spread is better than boulder. On Pit 3 Banko Barat, blasting using stemdeck results with uneven fragmentation size in condition of same powder factor and burden. This is caused by different rain intensity. Rainfall is causing blasting hole to be wet and decreasing the blasting capabilities of explosives. Blasting using stemdeck results in fragmentation average of 27.19 cm. Blasting without stemdeck based on same burden 8 m, results in fragmentation average of 46.46 cm and fragmentation size chart is obtained that shows increasing value as the powder factor from blasting geometry. That thing is contradictory with theory that the greater powder factor will result in uneven fragmentation size because it is connected with explosives usage. This condition is caused by the same doing to different rock structure on mining location in making blasting geometry design. Blasting without stemdeck based on same powder factor 0.16 kg/m3, results in fragmentation average of 66.26 cm and fragmentation size chart is obtained that is increasing as the value of burden. Smallest fragmentation value in average of 25.12 cm with 8 m burden and 0.17 kg/m3 powder factor. So if smaller fragmentation is needed in the future, then it is recommended to use smaller burden in making blasting geometry design.
The Un-Essay, and Teaching in a Time of Monsters
Authors: Irwin Ryan
Published: November 2022

This essay explores three examples of the Un-Essay---the recorded video, the podcast, and the multimedia lecture---arguing that each assignment advances traditional learning objectives like argumentation, information literacy, and narrative-making. As such, the author pushes against the premise that the Un-Essay is a “creative” alternatives to prose storytelling. To the contrary, the Un-Essay’s value arises from the way it teaches craftsmanship and self-awareness, two skills at the heart of the historian's craft. Embedding the Un-Essay into our curriculum can improve established learning objectives while leveraging technologies like TikTok and YouTube, leading to better outcomes that help more students understand the merits and complexities of historical thinking.

PETITION AS INDONESIAN FILM’S ROBBER: Theodor Adorno’s Perspective on Majority-Leaning Group’s Criticisms
Authors: Nugroho Sri Nugroho
Published: November 2022

Filmmakers have felt the impact of numerous films that have been petitioned or rejected by groups acting in the majority’s interests. The groups carry religious issues and view films as a new force capable of undermining the values (dogma) they believe. The views were infiltrated by efforts to homogenize discourses for a particular purpose rather than pure objectivity, resulting in petitions opposing certain films. In this regard, Adorno’s perspective on the revolutionary objective basis leads to the eradication of critical thinking against individuals associated with capitalism. The term “capitalists” refer to persons who control the Indonesian film industry. The underlying phenomena of this research are alienation and oppression, and the research sources are film industry actors who are directly affected by the phenomena above. Using Bogdan’s and Taylor’s qualitative approach in Moleong (2018), this study reveals that capitalists attempt to paralyze the joints of critical thinking to steer Indonesian films toward uniform themes, namely religious ones, that are “safe” from mass organizations’ petitions and rejections. These efforts mark the end of critical thinking and ideas in the creative filmmaking process.

Implementing a film festival on a digital platform could be a game-changer for the film industry in the Covid-19 era. It is then crucial to understand the role of digital platforms as a substitute for attending film festivals at JAFF 2020 because, in essence, films require spaces to interact with the audience regardless of the circumstances. This research is a qualitative study employing a case study methodology. The findings suggest that the role of digital platforms in implementing JAFF 2020 can be viewed as a means for a film festival to connect with its audience via new media. Additionally, the use of digital platforms is intended to act as a catalyst and carrier of energy for film crews to rise to the occasion in the face of a pandemic's uncertain conditions.
