The use of sea sand in construction work from an economic point of view does have advantages. One of them is increasing the income of the sea sand collectors who are spread throughout the area in Fakfak Regency. In addition, the potential availability of sea sand is quite large and is able to accommodate all types of concrete construction work in this area. This study aims to determine and analyze the use of sea sand in the AC-WC mixture of course by doing the Marshall test. This study uses variations in asphalt content of 5.0%, 5.5%, 6.0%, 6.5% and 7.0%, this study was carried out using Marshall testing in accordance with the general specifications of Bina Marga 2018. The results of the research conducted showed a relationship asphalt content and Marshall parameters such as stability value, VMA, density, MQ at an asphalt content of 5.0%-7.0%, meet the specifications of 1932 kg, 19.84%, 2.26 gr/cm3 and 1031 kg/mm. Values of VIM, VFWA and flow at 5.5% asphalt content are known to not meet the mix spasticity, namely 8.07%, 59.71% and 1.67 mm. Based on the Marshall parameter data, the Optimum Asphalt Content value is 6.5%.

Indonesia menjadi negara terbesar keenam di dunia sebagai produsen kakao dunia, setelah Côte d'Ivoire, Ghana, Ecuador, Cameroon, dan Nigeria. Sektor pertanian kakao Indonesia menjadi salah satu komoditi ekspor unggulan. Besarnya jumlah produksi kakao di Indonesia, tidak berbanding lurus dengan peran dan kontribusi generasi muda Indonesia untuk menekuni sektor pertanian kakao ini. Data memperlihatkan petani kakao dengan lahan kecil masih didominasi oleh petani yang berusia di atas 40 tahun. Metode pelaksanaan pengabdian berupa pemberian edukasi dan sosialisasi kepada generasi Y dan generasi Z tentang pentingnya kontribusi dan keterlibatan generasi muda Indonesia dalam sektor pertanian kakao. Hasil pengabdian ini diharapkan dapat menumbuhkan kesadaran dan minat generasi muda Indonesia dalam menjaga keberlangsungan sektor pertanian kakao dan dapat mewujudkan tercapainya salah satu tujuan dari Sustainable Development Goals.
