This study highlights the effect of (1) training and development, (2) Information and Communication Technology (ICT) skills, and (3) additional employee allowances (Tambahan Perbaikan Penghasilan or TPP) on teacher performance at UPT SMA Negeri I Palopo. This is a quantitative study in an ex post facto correlational design. The population includes the 60 entire teachers at UPT SMA Negeri 1 in Palopo City, from which a sample size is calculated using Slovin’s formula at a 5% confidence level. Instrument of data collection fits in a 5-scale Thurstone questionnaire that measures four variables, i.e., training and development(X1), ICT skills (X2), additional employee allowances(X3), and teacher performance (Y). SPSS 23 is used to run multiple regression for data analysis. Findings indicate that the partialeffect of X variables on teacher performance at UPT SMA Negeri 1 Palopo is 25,7% (training and development-X1), 43,1% (ICT skills-X2), and38,2% (additional employee allowances-X3). In terms of simultaneity, the influence of X variables on teacher performance is 45%. These findings suggest that the constructs of training and development, ICT skills, and additional employee allowance, both partially and simultaneously, are helpful for aiding in the improvement model of teacher performance. UPT SMA Negeri 1 Palopo can use these findings to define performance quality plan for its entire teacher workforce.

Green Open Space Planning (RTH) for urban areas needs to support ecological functions, education facilities, and social interaction facilities for urban communities and regional identity. As green open spaces, Complex Elementary Park and Reading Park in Palopo, South Sulawesi have not yet fulfilled their functions and benefits optimally. The two parks that are located in the heritage area become a unique/distinctive potential to show the historical connotation of the location in its design. This study aims to provide landscape design recommendations by exploring the potential of the location through the historical and cultural approach of the Luwu Kingdom. The research was conducted using a descriptive qualitative method that refers to the landscape planning of Seymour M. Gold through the stages of preparation, inventory, analysis, synthesis, and planning. The results of this study resulted in an Education Park site plan that elaborated the physical and philosophical characteristic of three cultural heritages, namely the Datu Luwu Palace Complex, the Jami' Mosque, and the Post and Giro Office. Konsep Taman Edukasi pada Perencanaan Ruang Terbuka Hijau melalui Pendekatan Sejarah dan Budaya. Perencanaan Ruang Terbuka Hijau (RTH) Kawasan Perkotaan perlu menunjang fungsi ekologis, wadah pendidikan, sarana interaksi sosial masyarakat urban dan identitas daerah. Sebagai RTH, Taman SD Kompleks dan Taman Baca di kota Palopo, Sulawesi Selatan belum menunjukkan terpenuhinya fungsi dan manfaatnya secara optimal. Kedua taman yang berada dalam kawasan heritage menjadi potensi khas/unik untuk menunjukkan historical connotation lokasi dalam desainnya. Penelitian ini bertujuan membuat rekomendasi desain lanskap dengan mengeksplorasi potensi lokasi melalui pendekatan sejarah dan budaya Kerajaan Luwu. Penelitian dilakukan menggunakan metode kualitatif deskriptif yang mengacu pada perencanaan lanskap Seymour M. Gold melalui tahapan persiapan, inventarisasi, analisis, sintesis dan perencanaan. Hasil penelitian ini menghasilkan siteplan Taman Edukasi yang mengelaborasi karakter fisik dan filosofis tiga cagar budaya yaitu Kompleks Istana Datu Luwu, Masjid Jami’ dan Kantor Pos dan Giro.

Over the past few years, attention to environmental problems, legal necessities, and economic advantages emerging from reproduction activities has attracted attention to reverse logistics activities in the form of a closed-loop supply chain, whether in industry or scientific research. The current study aims to model competitiveness and comparison between two closed-loop three-level supply chains, each of which includes a manufacturer, a retailer, and a third party to collect the products used by the customer, taking into account the concepts of game theory and the existence of aggregates. Moreover, a separate supplier for each chain is considered. In the forward supply chain, the manufacturer produces new products using new components or re-used products that have been collected from the consumer, then sells these products mainly to the retailer, and the retailer sells them. In the reverse chain, the collector provides the used products to the manufacturer after collection. The study utilized the definitions and concepts of game theory to model this closed loop chain as a Stackelberg game to obtain the optimal value of wholesale and retail price and the optimal value of the product return coefficient for the collector. Finally, the models based on some numerical examples are solved. Given the results, the remanufacturing costs have a significant role in making more profits for all members in such chains, and competitive chains should attempt to remanufacture the products at lower costs.
