Penelitian ini bertujuan untuk menjelaskan mengapa pihak ketiga melakukan perlawanan terhadap penetapan konstatering Ketua Pengadilan Negeri Praya, serta untuk menjelaskan bagaimana pertimbangan dari Pengadilan Negeri dalam melakukan konstatering terhadap tanah milik pihak ketiga yang tidak terlibat dalam perkara terdahulu. Peneltian ini menggunakan jenis penelitian hukum normatif. Adapun hasil dalam penelitian ini, alasan pihak ketiga mengajukan derden verzet dalam putusan karena pembantah sangat keberatan dengan dirugikannya hak-haknya sebagai pemilik yang sah atas tanah objek sengketa yang dibuktikan dengan Surat Hak Milik nomor 610 Desa Mekarsari atas nama Yunita Yusuf, yang akan dilakukannya konstatering oleh Pengadilan Negeri Praya. Selanjutnya pembantah tidak dilibatkan sebagai pihak yang berperkara dalam perkara terdahulu. Pertimbangan hukum Hakim Pengadilan Negeri Praya dalam putusan Nomor 77/Pdt.Bth/2019/PN.Pya adalah Majelis Hakim menolak bantahan Pembantah karena dianggap mengajukan bantahan yang tidak beralasan hukum dan pembantah tidak bisa membuktikan dalil bantahannya mengenai kepemilikannya terhadap tanah sengketa dalam perkara a quo. Akan tetapi didalam perkara konstatering ternyata pihak ketiga yang melakukan derden verzet mampu membuktikan sebagian objek konstatering sebagai hak miliknya sesuai sertifikat hak milik nomor 610 Desa Mekarsari atas nama Yunita Yusuf.

Indonesia is an agrarian country with subtropical climate suitable for planting multicultural and one of those plants is sugar cane. Sugar cane is a raw material for producing sugar, where biomass waste has not been utilized appropriately. The amount of biomass waste was produced of 24-30% from sugar mills. Effective, efficient and environmentally friendly waste treatment technology is needed to utilize the waste into a renewable energy source using gasification methods. Gasification is a process to convert biomass waste to combustible gases (CO, CH4, and H2). This process is combustion with limited air supply (20% -40% stoichiometric air) to break long hydrocarbon chains into short hydrocarbons at high temperatures. This method requires an updraft gasifier furnace that is capable of being operated at high temperatures, which can convert biomass waste into syngas with high conversion. An updraft gasifier is a gasification furnace at temperature of 300-500oC and atmospheric pressure, also used air flow of 10-20 L / min and zeolite as catalyst. This research are devided into few steps, namely drying, crushing, separating, gasification process, The proximate and ultimate method was used to analyze the produced syngas. Proximate analysis is an analysis to measure the calorific value by using a calorimeter bomb, ash content used AAF furnace, and moist water content used a decator. Moreover, ultimate method was used to analyze CH4, H2, O2, N2, CO and CO2 compositions by using Gas Chromatography (GC). Firstly, sugarcane bagasse as the main raw material, were dried and chopped in 7 cm then it were put into the gasifier. The results showed that maximum syngas ratio of combustible gas (CO, H2 and CH4) and noncombustible gas (NGC) of 1.03 with added the zeolit of 200 gr and water of 40 ,L/min.
