Penataan ruang yang baik mengurangi risiko bencana tanah longsor sesuai dengan tujuan penataan ruang sebagaimana tertuang dalam Undang-Undang Nomor 26 Tahun 2007 tentang Penataan Ruang yaitu untuk mewujudkan ruang wilayah nasional yang aman, nyaman, produktif dan berkelanjutan. Perwujudan ruang tersebut seharusnya tertuang dalam dokumen-dokumen rencana tata ruang yang terkait dengan keadaan risiko terhadap bencana. Peningkatan aktivitas pembangunan membutuhkan ruang yang semakin besar dan dapat berimplikasi pada perubahan fungsi lahan secara signifikan. Bencana tanah longsor dapat terjadi karena alih fungsi lahan menjadi lahan terbangun. Penelitian ini bertujuan untuk menganalisis nilai pengurangan risiko bencana tanah longsor akibat adanya rencana tata ruang wilayah. Penelitian bersifat kualitatif yaitu menganalisis rencana tata ruang dan kuantitatif yaitu analisis pemetaan risiko bencana. Hasil penelitian menunjukan bahwa Indeks bahaya/ ancaman bencana tanah longsor pada skenario eksisting berada pada kelas “bahaya sedang” karena mengalami pegurangan, namun pada skenario RTRW terjadi peningkatan pada kelas “bahaya tinggi” Meningkatknya luasan kelas bahaya longsor terjadi di enam dari delapan Kecamatan di Kota Lubuklinggau. Indeks Kerentanan bencana tanah longsor tidak mengalami perubahan yang signifikan antara skenario eksisting dengan skenario RTRW dimana semua skenario berada pada kelas kerentanan sedang. Indeks kapasitas bencana tanah longsor pada indeks kapasitas daerah berada pada level 2 yang berarti bahwa daerah telah melaksanakan beberapa tindakan pengurangan risiko bencana dengan pencapaian-pencapaian yang masih bersifat sporadis yang disebabkan belum adanya komitmen kelembagaan dan/atau kebijakan sistematis. RTRW Kota Lubuklinggau mengakibatkan kenaikan risiko bencana tanah longsor dengan Nilai Pengurangan Risiko (NPR) < 0 umumnya berada pada penggunaan lahan eksisting hutan alam atau pada kawasan rencana perkebunan. Luas area yang termasuk ke dalam NPR ini adalah sebesar 5.306,53 hektar atau 69,07 % dari luas Kota Lubuklinggau. Sedangkan Nilai Pengurangan Risiko (NPR) = 0 berarti wilayah tersebut tidak mengalami perubahan risiko akibat adanya RTR umumnya berada di penggunaan lahan eksisting sama dengan penggunaan lahan rencana (RTRW) misalnya kawasan Taman Nasional Kerinci Sebelat, hutan lindung Bukit Cogong, hutan produksi terbatas Hulu Tumpah, dan permukiman. Luas area yang termasuk ke dalam NPR ini adalah sebesar 11.334,93 hektar atau 30,93 % dari luas Kota Lubuklinggau. Berdasarkan hasil penelitian tersebut disarankan peningkatan kapasitas bencana melalui peningkatan kapasitas daerah dan kapasitas kesiapsiagaan bencana.

Cultivation of beef cattle in Indonesia is mostly carried out by smallholder farms. Therefore, the beef cattle assistance program from the government often involves farmer groups through a livestock raising system. This study aims to determine the impact of implementing various disturbance patterns applied by farmer groups on the development of beef cattle populations. The research was conducted from February to June 2021 in Padang Jaya District, North Bengkulu Regency. Data was collected through interviews with various informants, namely from the Agriculture Office of North Bengkulu Regency, Animal Husbandry Officers from Padang Jaya District, and Management of Farmer Groups. Reports on assistance for the livestock raising program in Padang Jaya District in the 2016-2020 period originating from the Agriculture Service became the basis for searching field information. Eight farmer groups from four recipient villages of the livestock raising program identified the patterns of disturbances and their impact on livestock population development. Secondary data related to this study were collected from BPS reports, Livestock and Animal Health Sector - North Bengkulu District Agriculture Service, and the Padang Jaya District Agricultural Extension Center. The data and information obtained are discussed descriptively. The results showed that there were four patterns of beef cattle raising applied by breeders, namely: (1) one calf deposit, (2) one calf deposit plus Rp. 300,000, (3) deposit of two children, and (4) patterns of rioting with a profit-sharing system. All of these rioting patterns increased the beef cattle population belonging to individual breeders, but only the rioting pattern with the deposit of two calves and a profit-sharing system was able to increase the population of ruminant livestock owned by farmer groups.

The construction of a Faecal Waste Treatment Plant (IPLT) in Tanjung Besar Village, South Kaur District, Bintuhan City, Kaur Regency in 2020 is one of the sanitation programs to help reduce the impact of pollution caused by fecal waste in the community environment with an integrated fecal waste processing system before being discharged into surface water. . According to data from the Public Works Sector Division of the PUPR Service as the manager of the Bintuhan City IPLT, this IPLT is not yet running, is still in the trial stage and will only be formed and a Management Decree (SK) will be proposed and is still in the stage of studying strategies and management in its management. Therefore, an analysis is needed to determine the ability to pay community fees as users of IPLT services. This research conducts a study of people's purchasing power which includes analysis of the ability to pay (abbreviated as ATP) and analysis of the willingness to pay (willingness to pay) abbreviated to WTP for the tariffs applied. In this research, questionnaires were distributed using a simple random sampling method and then the results were analyzed using the SPSS (Statistical Package for Social Sciences) and Microsoft Office Excel programs. Then the tariff calculation uses the ATP and WTP methods. The results of research on the community show that people who use fecal waste treatment installation services respond quite well in relation to waste water management. Proportional ATP Value Rp. 25,197.10,- greater than the Proportional WTP value of Rp. 10,064.76,- so it can be seen that the ability of IPLT service users to pay is greater than their willingness to pay. The results of the ATP and WTP calculations show that the applicable tariffs are in accordance with the ability and willingness of the IPLT user community in Bintuhan City.
