Judul: Potential Generation and Utilization of Household Waste Cooking Oil in Babakan Lebak Village, Dramaga District, Bogor Regency
Abstrak: Tingkat konsumsi minyak goreng yang tinggi mengakibatkan minyak goreng tidak digunakan hanya satu kali pakai sebagai upaya untuk penghematan. Minyak goreng yang dikonsumsi menghasilkan minyak goreng sisa atau yang biasa disebut minyak jelantah. Umumnya, minyak jelantah yang dihasilkan langsung dibuang ke selokan, tempat cucian piring, tempat sampah, dan lapangan luas atau lahan kosong. Perlakuan tersebut dapat berdampak pada penurunan kualitas lingkungandan selanjutnya berbahaya bagi kesehatan karena dapat membuat lingkungan tanah dan air tercemar. Berdasarkan kondisi tersebut, penelitian ini bertujuan 1) menghitung potensi timbulan minyak jelantah tingkat rumah tangga dan pengelolaannya saat ini, 2) menganalisis potensi pengelolaan minyak jelantah oleh rumah tangga, dan 3) menganalisis tingkat partisipasi warga terhadap pemanfaatan minyak jelantah di setiap rumah tangga. Metode yang digunakan adalah analisis deskriptif kualitatif, skala likert, dan analisis perbandingan. Hasil penelitian menunjukkan bahwa rumah tangga memiliki potensi yang cukup besar dalam menghasilkan minyak jelantah, terlebih bagi rumah tangga usaha makanan. Sebanyak 65% rumah tangga Desa Babakan Lebak memilih pengelolan minyak jelantah dengan cara mengumpulkan minyak jelantah yang mereka hasilkan dalam pengelolaan minyak jelantah, dibandingkan diolah menjadi sabun. Partisipasi warga masih dianggap rendah, hal ini dikarenakan ketidaktahuan informasi dan pengetahuan terkait maanfaat dan bahaya serta pengelolaan minyak jelantah. Perlu adanya tata kelola dan kelembagaan yang terintegrasi untuk meningkatkan partisipasi warga dan memudahkan pelaksanannya., The high level of cooking oil consumption causes cooking oil to be used more than once in an attempt to cut costs. The cooking oil consumed produces residual cooking oil, also known as waste cooking oil. Generally, waste cooking oil is dumped directly into sewers, dishwashers, trash cans, and large fields or vacant land. Such treatment will cause environmental damage and,will be harmful to health as well as pollute the soil and water environment. Based on these conditions, the purpose of this study is to 1) calculate the potential generation of waste cooking oil at the household level and its current management, 2) to analyze the potential waste cooking oil management by households, and 3)to examine the community participates in the reuse of waste cooking oil in each household. The descriptive qualitative analysis, Likert scale, and comparative analysis methods were used in this research. The results reveal that households, particularly those in the food service business, have a significant potential for producing used cooking oil. In Babakan Lebak Village, 65 percent of households choose their used cooking oil to be collected rather than processing it into soap. Citizen participation remained low, due to a lack of information and knowledge about the benefits and risks, as well as the disposal of used cooking oil. To increase citizen participation and facilitate implementation, integrated governance and institutions are required.

Judul: Estimation of The Value of Economic Benefit from  Household Waste Cooking Oil Management at Kebon Kopi Cibanteng Village,  Bogor Regency
Abstrak: Belum optimalnya pengelolaan minyak jelantah di Indonesia, membuat minyak jelantah berpotensi besar untuk dibuang begitu saja ke lingkungan. Penelitian ini bertujuan untuk mengestimasi timbulan minyak jelantah yang dihasilkan oleh rumah tangga di Kampung Kebon Kopi, menganalisis tingkat pengetahuan, sikap, dan perilaku rumah tangga dalam pengelolaan minyak jelantah di Kampung Kebon Kopi, serta mengestimasi nilai manfaat ekonomi dari pengelolaan minyak jelantah rumah tangga di Kampung Kebon Kopi. Metode penelitian yang digunakan yaitu deskriptif kuantitatif dengan pendekatan SNI-19-3964-1994 dan theory of planned behavior, analisis pendapatan, serta benefit transfer. Hasil penelitian menunjukkan bahwa rata-rata rumah tangga di Kampung Kebon Kopi menghasilkan minyak jelantah sebanyak 0,03 liter per harinya. Potensi timbulan minyak jelantah yang dihasilkan oleh seluruh rumah tangga di Kampung Kebon Kopi yaitu 3.118,44 liter per tahun dengan berat 2.599,09 kg per tahunnya. Mayoritas rumah tangga di Kampung.Kebon Kopi memiliki pengetahuan yang tinggi terkait minyak jelantah, sikap positif terhadap pengelolaan minyak jelantah, tapi belum menerapkan perilaku pengelolaan minyak jelantah. Nilai manfaat ekonomi yang diperoleh rumah tangga melalui pengelolaan minyak jelantah yaitu sebesar Rp2.024.853,00/KK/tahun., Waste cooking oil (WCO) management in Indonesia is not yet optimal. WCO has a great potential to be disposed of into the environment. This study aims to estimate the generation of WCO produced by households in Kebon Kopi Village, analyze the level of knowledge, attitudes, and behavior of households in the management of WCO in Kebon Kopi Village, and estimate the value of economic benefits from the management of household WCO in Kebon Kopi Village. The research method used was quantitative descriptive with the approach of SNI-19-3964-1994, theory of planned behavior, income analysis, and benefits transfer. The results showed that the average household in Kebon Kopi Village produces 0.03 liters of WCO per day. Furthermore, the potential WCO generated by all households in Kebon Kopi Village was estimated at 3,118.44 liters per year, with a weight of 2,599.09 kg per year. The majority of households in Kebon Kopi Village have high knowledge related to WCO, and positive attitudes towards used cooking oil management, but have not implemented WCO management behaviors.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
