“…It is therefore fundamental for us to know about the sociohistorical, sociopolitical and socioeconomical contexts under which Maphalla devised his poems to unambiguously depict the message conveyed in his literary work. Purba (2018) indicates that this approach seeks to understand a literary work by investigating the social, cultural and intellectual contexts that produced it -a context that necessarily includes the author's biography. Biographical data are used to analyse the literary work through the lens of the author's lived experiences.…”

In this article, we argue that KPD Maphalla’s poems were very influential in portraying protest to different forms of social oppression and exclusion in South Africa and Africa at large. Therefore, as a writer who was subjected to racial segregation during the apartheid regime, he positioned himself as a social poet concerned about the sociopolitical situation of Africans in Africa. The article illustrates how Maphalla’s use of tone and attitude towards racial discrimination has shown his ability to choose style in articulating a clear sociopolitical protest. This strategy has helped to make his readers aware of the social anomalies of his time, while condemning moral degeneration of that era. Therefore, this article provides an analysis of two poems from his book entitled Kgapha tsa ka: Mahlo a ka tutuboloha (My eyes open) and Ke ikopela tokoholo (I am asking for freedom), to understand the influence of the selected poems that are constructed in the form of protest. A historical-biographical criticism framework was employed in this case study to unravel the sociopolitical influence of his work towards the fight for freedom in South Africa. It is a qualitative explorative study, which uses purposive sampling to show how he portrays the theme of protest in his poems. Content analysis was used to analyse data guided by interpretivist paradigm.Contribution: This article fills a knowledge gap in Sesotho analysis. The article further contributes by highlighting Maphalla’s stance toward overcoming prejudice against black people. The article confirms that Maphalla, through his poetry, has played an important role in acting as a spokesperson for black people, and their freedom in South Africa.

“…A closer R 2 value to 1 indicates a greater influence, and vice versa. If the independent and dependent variables have no relationship, the R 2 value is negative [12,13]. In this study, the voltage was varied as 8, 10, and 12 volts.…”

Electrocoagulation is an electrochemical method that uses sacrificial electrodes to remove wastewater. The most common electrode material is aluminum, which serves as both the cathode and the anode. The electrodes are connected in bipolar mode and a power source is used to provide alternating current. Various operating parameters that can influence removal efficiency were investigated, including spacing between the electrodes, applied voltage, electrolysis time, initial BOD and COD concentrations. This study examined the efficacy of employing aluminum (Al) electrodes in the electrocoagulation procedure to lower the concentration of chemical and biological oxygen demand in leachate. This research was carried out by varying the voltage (8, 10, and 12 Volts), time (10, 20, and 30 min), and distance between the electrodes (1, 2, and 3 cm). The results showed that the combination of 12 Volt voltage, 30 min, and the greatest COD reduction percentage of 80.8% was obtained with a 2 cm gap between the electrodes, while the BOD reduction reached 82.3%. This research provides important insights into the leachate pollution treatment potential of electrocoagulation using aluminum electrodes. The optimal results can be used as a basis for further development of efficient and environmentally friendly leachate treatment.

Abstract. This research was conducted at PD. X is one of the companies that distributes bottled drinking water products in the city of Bandung and its surroundings and does not yet have a permanent transportation cost optimization calculation technique that can result in high distribution costs. These problems can be formulated in the transportation model. The method used to determine the initial feasible solution is Northwest Corner and Vogels Approximation, while determining the optimum solution using Stepping Stone. The results of the initial feasible solution calculation show that the number of iterations using the two methods is the same, namely eight iterations. The difference between these two methods is the transportation cost of Rp. 696,000 for the Northwest Corner method and Rp. 611,400 for the Vogels Approximation method. The results of the calculation of the optimal solution show that there are differences in the number of iterations. For the Northwest Corner and Northwest Corner methods, the number of iterations is seven, while the Vogels Approximation and Northwest Corner methods have two iterations. The optimal solution of the two methods obtained the same transportation costs of Rp. 600,400. Thus the Vogels Approximation and Northwest Corner methods are more analytically efficient. Abstrak. Penelitian ini dilaksanakan pada PD. X yaitu salah satu perusahaan yang mendistribusikan produk air minum dalam kemasan di daerah kota Bandung dan sekitarnya dan belum memiliki teknik perhitungan pengoptimalan biaya transportasi yang permanen sehingga dapat mengakibatkan biaya distribusi yang cukup tinggi. Persoalan tersebut dapat diformulasikan dalam model transportasi. Metode yang digunakan untuk penentuan solusi fesibel awal adalah Northwest Corner dan Vogels Approximation, sedangkan penentuan solusi optimum menggunakan Stepping stone. Hasil perhitungan solusi fesibel awal menunjukan bahwa jumlah iterasi menggunakan kedua metode tersebut sama yaitu sebanyak delapan iterasi. Perbedaan dari kedua metode ini terdapat pada biaya transportasi sebesar Rp. 696.000 untuk metode Northwest Corner dan sebesar Rp. 611.400 untuk metode Vogels Approximation. Hasil perhitungan solusi optimal menunjukan adanya perbedaan jumlah iterasi. Untuk metode Northwest Corner dan Northwest Corner jumlah iterasi yaitu tujuh, sedangkan metode Vogels Approximation dan Northwest Corner jumlah iterasi yaitu dua. Adapun solusi optimal dari kedua metode tersebut diperoleh biaya transportasi yang sama sebesar Rp. 600.400. Dengan demikian metode Vogels Approximation dan Northwest Corner lebih efisien secara analitik.
