Maka dari itu penyediaan prasarana haruslah memadai sehingga para pengunjung mendapatkan pelayanan yang bagus dan merasa nyaman untuk datang ke Gili Trawangan. Sehingga para pengusaha investor berlomba-lomba untuk mencari lahan perkebunan milik warga Gili Trawangan untuk dijadikan sebagai tempat membangun hotel, villa dan restaurant karena kedepannya sangat menguntungkan bagi para pengusaha. Ketersediaan lahan di Gili Trawangan yang kurang juga menjadi kendala tersendiri, dengan demikian terpaksa melakukan alih fungsi lahan perkebunan kelapa menjadi daerah pariwisata untuk memenuhi kebutuhan pariwisata. Tujuan dari penelitian ini adalah memetakan penggunaan lahan di Gili Trawangan untuk mengetahui laju alih fungsi yang terjadi dari tahun 2013 sampai 2021 serta faktor-faktor yang menyebabkan terjadinya alih fungsi lahan. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dan kualitatif. Pengolahan dan analisis data dilakukan dengan menggunakan ArcGis 10.4, yang mana tahapan-tahapannya meliputi koreksi geometrik, dan interpretasi citra. Data yang digunakan adalah data citra satelit dengan periode perekaman dari tahun 2013-2021. Hasil analisis menunjukan bahwa perubahan tata guna lahan yang terjadi pada Gili Trawangan selama kurun waktu sembilan tahun, dari tahun 2013 sampai dengan 2021 yaitu sebesar 136,19 Ha dengan laju alih fungsi sebesar 434,96%. Perubahan terjadi pada lahan perkebunan, lahan vegetasi non budidaya, dan lahan terbuka menjadi lahan sarana dan prasarana wisata. Faktor-faktor yang menyebabkan alih fungsi lahan yaitu banyak terjadinya pembangunan sarana dan prasarana pariwisata. Faktor lainnya yaitu dari segi ekonomi hasilnya lebih menguntungkan dibandingkan dengan menjadi petani kelapa, dan dapat membuka lapangan pekerjaan yang luas bagi masyarakat.","PeriodicalId":424353,"journal":{"name":"Journal of Soil Quality and Management","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126025786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consistency describes how accurate the results of the forecast are. If the percentage of the consistency value is above 50%, it means that it is better to predict using the forecasting method by looking for consistency than using the average.

Two main parameters were tested, namely the dispersion ratio and the stability of soil aggregates. The results showed that the average value of the ratio of land dispersion indicated by coffee-based agroforestry was 79.85% and the highest was clove-based agroforestry of 91.56%, these values ​​belong to the highly dispersed class. Unlike the case with soil aggregate stability, the highest average soil aggregate stability value was shown in coffee-based agroforestry of 109 and the lowest was clove-based agroforestry of 60.
