Abstract

Pupuk organik cair NASA ialah pupuk organik natural dari ekstrak bahan organik limbah ternak serta unggas, limbah sebagian tumbuhan tertentu dan zat-zat natural yang lain yang diproses dengan teknologi ramah lingkungan. Percobaan ini memiliki tujuan agar dapat mengetahui konsentrasi POC NASA yang pas bagi 5 varietas bawang merah yang ditanam di Wamena. Penelitian disusun dalam bentuk rancangan acak kelompok dua faktor. Faktor 1 berupa 5 varietas bawang merah, seperti Crok, Tiron, super Biru dan Bima serta satu varietas lokal Wamena sebagai pembanding. Sedangkan faktor 2 terdiri atas 3 taraf konsentrasi POC NASA yakni: 0 ml, 150 ml dan 250 ml. Informasi hasil penelitian dianalisis memakai ANOVA taraf 5 %. Apabila berpengaruh nyata, maka pengujian dianalisis lanjut dengan tes jarak berganda Duncan Multiple Range Test (DMRT) 5%. Hasil percobaan membuktikan bahwa produktivitas tanaman bawang merah dipengaruhi oleh interaksi antara konsentrasi POC NASA dengan varietas bawang merah. Hasil penelitian memperlihatkan adanya interaksi nyata oleh perlakuan POC NASA 150 ml dengan varietas Super Biru pada parameter tinggi tanaman dan bobot segar akar, kemudian perlakuan POC NASA 250 ml dengan varietas Lokal Wamena pada parameter bobot kering daun, selanjutnya perlakuan POC NASA 250 ml dengan varietas Bima pada pengamatan kandungan klorofil a dan jumlah daun.

Abstract

This study compares the degree of adaptation of four shallot varieties introduced to the sub-optimal land of Wamena with one local variety. The study determined the physiological processes of plants observed 5 and 11 weeks after planting. The results show that the best-adapted shallot is the local variety which is indicated by the parameter of harvest index (0.820). In addition, the results showed that the local Wamena variety produced high production with a high assimilation rate (0.072 g/dm2week-1), had a leaf area (41,750 cm) and a high leaf area value (0.465 cm) even though it was indicated by treatment without fertilizer application. Liquid organic (control treatment). Compared with the introduced varieties, which showed no significant effect on each liquid organic fertilizer treatment level. The difference in responses shown by each variety is influenced by the genetic ability of each variety which is supported by environmental conditions.

Abstract

Kelurahan Petoaha, Kecamatan Abeli, Kota Kendari merupakan salah satu desa yang memiliki potensi perkebunan kelapa yang cukup luas. Potensi perkebunan kelapa yang cukup luas tentunya akan menimbulkan limbah seperti batok kelapa/tempurung kelapa. Oleh karena itu, tujuan program pengabdian kepada masyarakat ini adalah untuk memanfaatkan limbah biomassa batok kelapa menjadi bio-briket terdoping smart liquid TiO2 sebagai bahan bakar alternatif ramah lingungan. Adapun tahapan pelaksanaan kegiatan bio-briket diawali dengan survey lokasi kegiatan, sosialiasi, pelatihan dan pendampingan pembuatan bio-briket batok kelapa terdoping smart liquid TiO2.pada masyarakat pesisir Petoaha. Berdasarkan hasil kegiatan menunjukkan bahwa masyarakat Desa Petoaha, Kecamatan Abeli telah memperoleh wawasan dan keterampilan terkait peluang pemanfaatan limbah biomassa batok kelapa untuk pembuatan bio-briket terdoping smart liquid TiO2 sebagai alternatif bahan bakar alternatif.

Abstract

In an effort to enhance the performance of lithium-ion batteries (LIBs), this study developed a NiO-TiO2-CuO nanocomposite supported by reduced graphene oxide (rGO) as an anode material. The nanocomposite was synthesized via a hydrothermal method and characterized using FTIR, XRD, and SEM-EDX techniques to understand its structure and material properties. The FTIR spectrum confirmed the presence of C=C bonds (1612-1512 cm-1) and C–O bonds (1147-1099 cm-1) from rGO, as well as Ni-O (408 cm-1), Cu-O (669 cm-1), and Ti-O (549 cm-1). The XRD patterns revealed the crystalline phases of NiO at 2θ = 37° (111), 43° (200), and 62.8° (200); TiO2 at 2θ = 25.3° (101), 48° (101), and 55° (211); and Cu-O at 2θ = 35.6° (111) and 39.8° (022). SEM-EDX images showed small aggregated particles forming a relatively uneven surface with spherical morphology, with an average particle size of 33.25 nm. Electrochemical testing using cyclic voltammetry (CV) demonstrated that the material exhibited a stable specific capacity (Csp) of 6.3 mAh/g after five cycles at a scan rate of 1 V/s. Additionally, the specific capacity significantly increased to 44.15 mAh/g at a scan rate of 0.05 V/s, indicating excellent electrochemical performance. These results suggest that the NiO-TiO2-CuO/rGO nanocomposite has potential as an efficient anode material for lithium-ion battery applications, offering good cycle stability and enhanced energy storage capacity.

Abstract

This study synthesizes and characterizes NiO–TiO₂/graphene nanocomposites as anode materials to enhance the performance of lithium-ion batteries (LIBs). The composite was prepared using NiO precipitation, TiO2 annealing, and hydrothermal methods. FTIR analysis identified -OH stretching vibrations at 3313.63 cm-1 and Ni-O/Ti-O bonds at 624 cm-1, confirming metal oxide formation. XRD revealed anatase TiO2 phases at 2θ = 25° and 48° with (101) and (200) planes, rutile phases at 2θ = 27°, 36°, and 54° with (110), (101), and (211) planes, and peaks for graphene (2θ = 43°) and NiO (2θ = 62° and 70°). SEM-EDX showed uniform nanoparticle morphology with Ti, O, Ni, and C elements. Cyclic voltammetry indicated a 5% capacity increase per cycle over five cycles, with oxidation at 0.75 V and reduction at -0.75 V. The composite demonstrated excellent electrochemical stability and enhanced storage capacity, highlighting its potential as an anode material for LIBs.
