Judul: Community Participation in Ecosystem Restoration Programme in the Upper Ciliwung Watershed
Abstrak: Degradasi lahan di kawasan puncak Bogor meningkat setiap tahunnya yang dipicu oleh faktor alam seperti tindakan manusia yang eksploitatif. Desa Tugu Utara sebagai bagian dari kawasan puncak dan Hulu DAS Ciliwung turut mengalami degradasi lahan karena terletak di sekitar kawasan destinasi wisata yng menyebakan terjadinya alih fungsi lahan secara besar-besaran, sehingga kemudian memicu terjadinya longsor di bagian hulu dan banjir di daerah hilir. Pemerintah setempat dan berbagai pihak telah melakukan upaya penanaman pohon di lahan kritis wilayah Hulu DAS Ciliwung melalui kegiatan konsorsium kawasan puncak pada tahun 2014. Kurangnya partisipasi masyarakat menyebabkan program ini tidak berhasil, sehingga pada tahun 2018 dibentuklah sebuah program Pemulihan Ekosistem yang dipelopori oleh Pusat Pengkajian Perencanaan dan Pengembangan Wilayah Lembaga Penelitian dan Pengabdian kepada Masyarakat (P4W LPPM) IPB bekerja sama dengan Perhutani KPH Bogor, dan Pemerintah Desa dengan tujuan pemulihan ekosistem yang menekankan partisipasi aktif dari masyarakat sebagai kunci keberhasilan program ini. Penelitian ini bertujuan untuk menganalisis perubahan tutupan lahan yang terjadi di Desa Tugu Utara, menganalisis karakteristik masyarakat setempat, tingkat partisipasi masyarakat dalam program Pemulihan Ekosistem di Hulu DAS Ciliwung, faktor-faktor yang memengaruhi partisipasi masyarakat, tingkat partisipasi masyarakat, serta menentukan alternatif strategi terbaik untuk meningkatkan partisipasi masyarakat dalam program Pemulihan Ekosistem di Hulu DAS Ciliwung. Metode penelitian yang digunakan adalah analisis tutupan lahan Land Use Land Cover (LULC), analisis kualitatif tentang karakteristik masyarakat, analisis regresi linier berganda, analisis People Participation Index (PPI) dan analisis tingkat partisipasi Arnstein 1969, analisis regresi linier berganda, serta analisis SWOT. Hasil penelitian menunjukkan terjadinya perubahan tutupan lahan dalam 10 tahun (2011 – 2021) yang didominasi oleh perubahan kelas hutan tanaman seluas 869,62 ha menjadi perkebunan, hutan lahan kering sekunder, pemukiman, dan pertanian lahan kering. Faktor-faktor yang berpengaruh signifikan terhadap partisipasi masyarakat meliputi usia, pendidikan, pekerjaan, pendapatan, jumlah tanggungan, keluarga, lama berusaha tani, intensitas penyuluhan, peran penyuluh, ketersediaan sarana, dan peran kelompok tani hutan (KTH). Tingkat partisipasi masyarakat dalam program pemulihan ekosistem berdasarkan People Participation Index (PPI) termasuk dalam kelas menengah, dan termasuk dalam tingkatan partisipasi degress of tokenism berdasarkan tingkat partisipasi Arnstein. Berdasarkan analisis SWOT diperoleh bahwa strategi S-O (strenght – opportunity) merupakan alternatif strategi terbaik dalam menangani masalah dalam program Pemulihan Ekosistem di Hulu DAS Ciliwung., Land degradation in Puncak Bogor area increases yearly, and it’s triggered by natural factors such as exploitative human actions. Tugu Utara Village, as part of the Puncak area and the Upper Ciliwung Watershed, is also experiencing land degradation because it is located in the vicinity of a tourist destination has led to extensive land sales by both the private sector and local communities, causing massive land conversion and triggering landslides on the upstream and flooding in the downstream area. To resolve the problem, the local government and researchers have made various efforts, including planting trees on critical land through the Puncak area consortium in 2014. However, the lack of community participation caused the program to be unsuccessful. Thus, in 2018, an Ecosystem Recovery process initiated by P4W LPPM IPB in collaboration with Perhutani KPH Bogor and the Village Government was established with the aim of emphasizing the active participation of the community as the

Judul: Efektivitas Kelembagaan Partisipatoris di Hulu Daerah Aliran Sungai Citarum (Studi Kasus Komunitas Cikapundung Rehabilitation Program dan Komunitas Zero, Kecamatan Coblong, Kota Bandung, Provinsi Jawa Barat)
Abstrak: Upstream watershed is one of the sub-watersheds that serve to maintain the availability of water for the central and downstream region. So that, when damage occurs in that area, it will effect to the middle and lower area of the watershed. The purposes of this study were (1) to determine the stakeholders who involved in the rescue of Citarum watershed upstream, (2) to know the effectiveness of participatory institutions to change attitudes and behavior of society around the Citarum watershed upstream. This study was conducted using a quantitative approach supported by qualitative approach. Meanwhile, the results of this study showed (1) institutional participatory have successfully changed attitudes and behavior of society to not to dispose the household garbage and sewage into the river again (2) participatory institutional not yet managed to change the manner of private parties to not to dispose garbage and industrial waste into the river, and (3) participatory institutions in central are more effective to change society attitudes and behavior to be more concerned for the environment than the existing participatory institutions in the upstream. In generally, the participatory institutions have successfully established collaborative between public, private and government at the sub-watershed upstream

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
