    Abstrak. Permasalahan pupuk, lahan terdegradasi, dan pencemaran, pengelolaan sumberdaya lahan rawa, dan pengelolaan sumberdaya air yang terbatas di lahan pertanian, merupakan isu atau permasalahan mendesak yang harus dicari pemecahannya. Untuk mengatasi permasalahan tersebut, Balai Besar Litbang Sumberdaya Lahan Pertanian (BBSDLP) telah menghasilkan beberapa teknologi yang siap diaplikasikan. Dalam dua tahun terakhir, output hasil penelitian BBSDLP tersebut dalam bentuk produk teknologi dan rekomendasi anjuran teknologi sumberdaya lahan telah diaplikasikan dan dimanfaatkan dalam mendukung program prioritas sektor pertanian. Program prioritas dimaksud, adalah: (1) program selamatkan rawa dan sejahterakan petani disingkat SERASI, (2) program penurunan pencemaran lingkungan, (3) program peningkatan produktivitas pertanian dan (4) program antisipasi perubahan iklim. Terdapat opini yang paradoks, institusi lembaga riset menganggap bahwa banyak teknologi hasil penelitian yang siap diaplikasikan, tetapi menurut sebagian petani sangat terbatas teknologi hasil penelitian yang siap dimanfaatkan petani. Untuk itu perlu analisis secara seksama sehingga memperoleh gambaran yang akurat dan dimana letak permasalahannya serta bagaimana cara mengatasinya agar teknologi hasil penelitian tersebut efektif. Hasil evaluasi awal beberapa teknologi yang dimanfaatkan dalam program prioritas tersebut telah menunjukkan nilai tambah atau nilai indeks efisiensi teknis dalam bentuk meningkatkan produktivitas hasil (sekitar 30%) atau efisiensi penggunaan input produksi (contohnya mengefisiensikan penggunaan pupuk N,P sebesar 20%), walaupun masih perlu kajian lebih lanjut, apakah teknologi tersebut berpotensi memberikan dampak potensial (potential impact). Sebagian besar teknologi unggulan tersebut menunjukkan dampak awal (initial impact) yang positif dalam bentuk penyebaran dan aplikasi teknologi oleh petani di wilayah pengembangan.  Abstract. The problem of fertilizer, degraded land, and pollution, management of swampy land resources, and management of limited water resources on agricultural land, are urgent issues or problems that have to be resolved. To overcome these problems, ICALRD has produced several technologies that have been and are ready to be applied. In the last two years, it has been shown that some of the outputs of research results in the form of technological products and recommendations for land resource technology have been applied and utilized in supporting the priority programs in the agricultural sector. The priority programs referred to are: (1) safe the peat swamp and increased farmer’s welfare program abbreviated as SERASI, (2) environmental pollution reduction program, (3) agricultural productivity improvement program and (4) climate change anticipation program. There is a paradox opinion between beween research institute and farmers; where many technologies have been resulted by research institute and ready for application but according to some farmers only few technologies are available and applicable. For this reason, a careful analysis is needed to assess what the problems are and how to overcome them so that the research technology is more effective. Initial evaluation results of several technologies utilized in the priority program have shown the added values or technical efficiency index values in the form of increasing yield productivity (around 30%) or efficient use of production inputs (eg efficient use of N, P fertilizers up to 20%). However, there is still a need for further study to determine whether the technology is promishing to have a potential impact. Most of the leading technologies show positive initial impacts in the form of technological dissemination and application by farmers in development areas.

    Areal Taman Nasional Kerinci Seblat (TNKS) di wilayah penyangga Kabupaten Pesisir Selatan mengalami degradasi hutan tertinggi diantara daerah-daerah penyangga lainnya, yaitu mencapai 1.570 ha atau 34,23% dari luas total degradasi hutan yang terjadi di seluruh kawasan TNKS. Fakta tersebut diduga erat kaitannya dengan kegiatan illegal logging dan kondisi sosial ekonomi masyarakat desa penyangga. Salah satu pendapatan hutan pada masyarakat desa penyangga diantaranya adalah hasil kayu dari kegiatan illegal logging. Penelitian ini dimaksudkan untuk mengkaji proporsi pendapatan dari hutan pada masyarakat desa penyangga, serta menganalisis pengaruh fakior-faktor sosial ekonomi rumah tangga terhadap pendapatan hutan. Metode penelitian yang yang digunakan adalah gabungan antara wawancara terstruktur dengan menggunakan kuesioner dan wawancara tidak terstruktur. Analisa data dilakukan secara deskriptif dan analisis regresi linear berganda. Hasil penelitian ini menunjukkan bahwa pendapatan masyarakat dari kayu balok jauh lebih besar dibandingkan dengan pendapatan hasil hutan lainnya. Pendapatan dari hasil kayu (kayu balok) mencapai Rp 282.499,- atau 66,05% dari total pendapatan/bulan. Hasil analisis regresi berganda menunjukkan bahwa faktor Umur Responden dan Jumlah Anggota Rumah Tangga, memiliki pengaruh signifikan terhadap peningkatan dan penurunan pendapatan masyarakat dari hutan

    This research article is a summary of the results of the group research that aims to describe the formulation of the denied style seen from uslub nahwi-bahalaghi. Sources of data were taken through the Qur\u27an Manuscripts documentation published by the Department of the Ministry of Religious Affairs in 1990 in collaboration with the Department of Islamic, Endowments and Propagation Affairs Kingdom of Saudi Arabia. The object of research is focused on the formulation of a set of spoken language style denied by the infidels and idolaters. The data were collected through documentation and recording format. Then the data is analyzed qualitatively through jawanib nahwiyah-balaghiyah and quantitatively through frequency, percentage, mean, and range. The results showed that of uslub nahwi, denied style is using uslub nahwi consisting of terms: qasam, and tahdid, while from uslub balaghi, denied uslub is using qashar, amr, nahy, and istifham. Denied sslub arised because of personality factors including attitudes, syirk beliefs, accuseing themselves as God\u27s sons and beloved, swearing not shirk, assumption of that Ezra and Jesus were the son of God; assumption of that the Qur\u27an is the tales of the past; asssumption of that preacher is weak reasonable, sorcerer, liar, lunatic, preventor of their worship, prohibition of hearing the Qur\u27an; assuming that the believer is someone misguided and ridiculous; and assumptions of that they could bear the sins of the believers

    In this work, the role of reduced graphene oxide (rGO) with hyperbranched surfactant and its hybridisation with multiwalled carbon nanotubes (MWCNTs) and platinum (Pt) nanoparticles (NPs) as counter electrode (CE) were investigated to determine the photovoltaic performance of dye-sensitised solar cells (DSSCs). Sodium 1,4-is(neopentyloxy)-3-(neopentyloxycarbonyl)- 1,4-dioxobutane-2-sulphonate (TC14) surfactant was utilised as dispersing and stabilising agent in electrochemical exfoliation to synthesise graphene oxide (GO) as initial solution for rGO production prior to its further hybridisation and fabrication as thin film. A chemical reduction process utilising hydrazine hydrate was conducted to produce rGO due to the low temperature process and water-based GO solution. Subsequently, hybrid solution was prepared by mixing 1 wt% MWCNTs into the produced rGO solution. TC14-rGO and TC14-rGO_MWCNTs hybrid solution were transferred into fluorine-doped tin oxide substrate to fabricate thin film by spraying deposition method. Finally, the CE films were prepared by coating with thin Pt NPs. Photoanode film was prepared by a two-step process: hydrothermal growth method to synthesise titanium dioxide nanowires (TiO2 NWs) and subsequent squeegee method to apply TiO2 NPs. According to solar simulator measurement, the highest energy conversion efficiency (η) was achieved by using CE-based TC14-rGO_MWCNTs/Pt (1.553%), with the highest short current density of 4.424 mA/cm2. The highest η was due to the high conductivity of CE hybrid film and the morphology of fabricated TiO2 NWs/TiO2 NPs. Consequently, the dye adsorption was high, and the photovoltaic performance of DSSCs was increased. This result also showed that rGO and rGO_MWCNTs hybrid can be used as considerable potential candidate materials to replace Pt gradually
