How people enjoy games, especially online games, is seen as an opportunity to attract visitors, in this case marketplace visitors. In contrast to offline stores where visitor traffic can be increased through various gimmicks, events, and so on. One of the efforts that the marketplace can make to increase visitor traffic is through the provision of online game services. The fun, addictive nature of the game has made market participants interested in incorporating game elements into a business that is not related to games. This became known as gamification. Marketplace X is one of the marketplaces that provides gamification game services. With repeated visitors accessing the gamification, it is hoped that the marketing efforts of Marketplace X will be exposed to users. This study intends to determine whether there is a relationship between gamification and the interest in revisiting the marketplace. This study uses quantitative research methods supported by SPSS data processing tools to test hypotheses. The data collection technique uses a purposive sampling technique in which the respondents are those who have played gamification in marketplace X and are domiciled in the city of Bandung. The results show that the gamification offered by Marketplace X is considered good by respondents and respondents have a high intention to revisit the marketplace in the future. In addition, there is a fairly strong correlation between gamification and re-visit intention. Therefore, Marketplace X needs to manage its gamification well to attract repeat visits, which is one way to marketing its products. Keywords: gamification, online games, marketplace, re-visit intention

ABSTRAK PT CSD dikategorikan sebagai marginal ore deposit dengan kadar berkisar 6 gpt mengacu pada klasifikasi kadar emas di Indonesia. Oleh karena itu, strategi penambangan menjadi pertimbangan penting untuk mendapatkan nilai yang lebih ekonomis (Purwanto, 2015). Berdasarkan laporan investigasi geoteknik, ratio tekanan in-situ vertikal dan horizontal di Cibaliung adalah 4.8 MPa:9.2 Mpa atau 1:2, yang berarti tekanan horizontal di Cibaliung dua kali lebih besar dibandingkan dengan tekanan vertikalnya (Campi dan Dugan, 2004). Secara sederhana bisa disimpukan bahwa strategi untuk mempercepat aktifitas produksi secara aman lebih baik dilakukan penambahan ketinggian pada bukaan front produksi dari pada memperlebar dimensi bukaan. Dari sudut pandang biaya pengerjaan bukaan front, biaya metode full face lebih murah ketimbang metode top heading and benching. Adapun untuk tingkat keamanan maka berlaku sebaliknya (Bin Zhu dan Xiaojing Shi, 2013). Analisa keekonomisan pada kegiatan penambangan perlu juga mempertimbangkan tonase ore yang terekstrak/perolehan logam Au untuk menentukan skema mana yang paling sesuai. Pemilihan skema penambangan menggunakan metode Analytical Hierarchy Process (AHP) dengan menggunakan tiga kriteria (kestabilan, biaya penambangan, tonase ore) dan empat pilihan skema (full face 1, full face 2, THB 1 dan THB 2). Hasil perhitungan menggunakan metode AHP didapatkan peringkat skema tertinggi sampai terendah: full face 1 (0.343), THB 2 (0.260), THB 1 (0.215), full face 2 (0.182). Kata Kunci: analisa kestabilan, studi keekonomisan, metode AHP, strategi penambangan  ABSTRACT PT CSD is categorized as a marginal ore deposit with ore grade around 6 ppm, based on the classification of gold grade in Indonesia. Therefore, the mining strategy is an important consideration to get a more economical value (Purwanto, 2015). Based on the geotechnical investigation report, the ratio of vertical and horizontal in-situ pressure in Cibaliung is 4.8 MPa: 9.2 Mpa or 1: 2, which means the horizontal pressure in Cibaliung is twice as high as its vertical pressure (Campi and Dugan, 2004). In simple terms it can be concluded that the strategy to accelerate production activities safely is heightening rather than widening the dimension of the production stope. From the point of view of tunnel/stope construction cost, the cost of the full face method is cheaper than the top heading and benching method. As for the security level, the opposite applies (Bin Zhu and Xiaojing Shi, 2013). Economic analysis in mining activities also needs to consider the tonnage of ore extracted / Au produced for deciding which scheme is appropriate. The selection of mining schemes uses the Analytical Hierarchy Process (AHP) method using three criteria (stability, mining costs, ore tonnage) and four scheme options (full face 1, full face 2, THB 1 and THB 2). The results of calculations using the AHP method obtained the highest to lowest scheme ratings: full face 1 (0.343), THB 2 (0.260), THB 1 (0.215), full face 2 (0.182). Key Words: stability analyses, economic study, AHP method, mining strat

Perkembangan start-up sorgum terbilang cukup pesat dewasa ini. Sorgum mulai banyak diminati karena masyarakat mulai mengenal sorgum sebagai bahan pangan yang memiliki banyak keunggulan. Semakin berkembangnya start-up sorgum timbul masalah dimana customer kurang mengetahui penjual sorgum. Begitu juga sebaliknya, start-up sorgum memiliki cakupan konsumen yang kurang luas sehingga penjualan produknya pun tidak maksimal. Dengan metode pengelompokkan jenis varietas sorgum dan penyesuaian minat konsumen terhadap varietas sorgum, menggunakan sistem penjualan yang berbasiskan web diharapkan bagi start-up dapat menambah jangkauan konsumennya. Di sisi lain konsumen bisa lebih mudah mengetahui penjual sorgum, sehingga konsumen dapat membeli sorgum sesuai dengan varietas kebutuhan mereka.
