Hikmah et al, 2017. Characterization of Agronomic Traits on Two Rainfed Rice Varieties on Several Levels of Nitrogen Fertilizers and Water Treatments. JLSO 6(2):176-184.Rainfed rice varieties are expected to increase yield on rainfed fields. This research aim was to identify various agronomic characters including yield of rainfed rice varieties. It was conducted at the Sukamandi Field Station at rainy season 2016/2017, using a split split plot design with 4 replications. Water management as the main plot with two levels (I1: irrigated and I2: rainfed). Nitrogen (N) fertilizer dosage as subplot with three levels (P1: 0 kg N/ha, P2: 60 kg N/ha, and P3: 120 kg N/ha) and varieties as subplots with two levels (V1: Inpari 39 Tadah Hujan Agritan and V2: Inpari 41 Tadah Hujan Agritan). The results showed that water treatment and N dosage on each variety gave different response on their agronomic characters, including yield. Tiller numbers per hill was strongly influenced by water management and dosage of N fertilizer. In irrigated treatment, tiller number increased linearly increasing N dosage. In rainfed,Inpari 41 Tadah Hujan Agritan reach maximum tiller number with 80 N kg/ha which more efficient than Inpari 39 Tadah Hujan Agritan with 91,97 N kg/ha. Rice yield was significant effected by N fertilizer and the genetic trait of each variety. The yield of Inpari 41 Tadah Hujan Agritan was higher than the Inpari 39 Tadah Hujan Agritan. Inpari 41 Tadah Hujan Agritan reached 5.70 t/ha GKG and Inpari 39 Tadah Hujan Agritan 4.62 t/ha.

ABSTRACTANALYSIS AND DESIGN OF NUCLEAR ENERGY INFORMATION SYSTEMS. Management of research reports and activities of the Center for Nuclear Energy System Assessment (PKSEN), either in the form of documents and the results of other activities, are important part of the series of activities PKSEN mission achievement. Management of good documents will facilitate the provision of improved inputs or use the maximum results. But over the past few years, there are still some problem in the management of research reports and activities performed by PKSEN. The purpose of this study is to analyze and design flow layout of the Nuclear Energy Information System to facilitate the implementation of the Nuclear Energy Information System. In addition to be used as a research management system and PKSEN activities, it can also be used as a information media for the community. Nuclear Energy Information System package is expected to be "one gate system" for PKSEN information. The research methodology used are: (i) analysis of organizational systems, (ii) the analysis and design of information systems; (iii) the analysis and design of software systems; (iv) the analysis and design of database systems. The results of this study are: had identified and resources throughout the organization PKSEN activation, had analyzed the application of SIEN using SWOT analysis, had identified several types of devices required, had been compiled hierarchy of SIEN, had determined that the database system used is a centralized database system and had elections MySQL as DBMS. The result is a basic design of the Nuclear Energy Information System) which will used as a research and activities management system of PKSEN and also can be used as a medium of information for the community.Keywords: analysis, design, information systems, nuclear energy.

Abstract

ABSTRAK PERKIRAAN PARTISIPASI INDUSTRI NASIONAL DALAM PEMBANGUNAN PLTN HTR. Salah satu aspek penting dalam penyiapan infrastruktur pembangunan PLTN adalah aspek keterlibatan industri nasional. IAEA memberi rekomendasi bahwa perlu dilanjutkan untuk persiapan fase 2, yakni dengan aspek kebijakan penetapan tingkat partisipasi nasional. Tujuan kajian ini adalah memperkirakan tingkat partisipasi nasional dengan mengetahui tingkat kandungan komponen dalam negeri untuk reaktor tipe HTR berdaya kecil. Metodologi yang digunakan adalah studi literatur, membandingkan hasil kajian potensi industri nasional untuk sistem teknologi PLTN tipe LWR  dengan tipe HTR, melakukan perhitungan perkiraan tingkat partisipasi industri nasional berbasis biaya modal atau investasi yang lingkupnya dibatasi untuk jenis PLTN tipe HTR berdaya kecil dan hanya untuk proyek pembangunan unit pertama. Hasil studi menunjukkan bahwa dibandingkan dengan untuk pembangunan PLTN tipe LWR berdaya menengah hingga besar, tingkat partisipasi nasional dalam pembangunan PLTN diperkirakan sebesar 30%, namun bila dibandingkan dengan pembangunan PLTN tipe HTR berdaya kecil, tingkat partisipasi nasional sebesar 36% (kontrak putar kunci) dan sekitar 38% (kontrak Multi-Package).berdasarkan hal ini, direkomendasikan untuk memilih tipe kontrak putar kunci, hal ini mengingat belum ada pengalaman dalam membangun PLTN. Kata kunci: partisipasi industri nasional, HTR, daya kecil ABSTRACT ESTIMATION OF NATIONAL INDUSTRI PARTICIPATION ON HTR CONSTRUCTION. One of the important aspect in infrastructure preparedness of NPP construction is national industri involvement aspect. IAEA recommended that it required to  continue to the phase 2 by establishing the policy of national participation level decision.The objective of this paper is to estimate the level of local content component or national participation level especially for small HTR type reactor. Metodology used are literature study, comparison of NPP technology system which has been assessed the national participation potention with HTR type of NPP, calculation on national industri participation level estimation based on previous calculation that based on capital cost or investment cost. This estimation scope is limited only on small HTR type of NPP and only for construction project of the first unit. The results show that (a) Based on several studies which has been done, the result of previous national participation study for NPP (for medium and large unit size) construction is 30%. (b) Based on the latest national industri capability data and comparing with previous study, it is estimated that national indusrty participation level is 36% for turnkey contract and about 38% for Multi-Package contract. It is recommended that for the first NPP project would better with the turnkey contract type. Keywords: national industri participation, HTR, small unit size

Abstract

Kawasan PUSPIPTEK Serpong merupakan kawasan teknologi tinggi sesuai Rencana Tata Ruang Wilayah (RTRW) Kota Tangerang Selatan, 2011-2031, sehingga kawasan ini ditetapkan sebagai tapak Reaktor Daya Eksperimental (RDE). Untuk menjamin keselamatan, evaluasi tapak dari berbagai aspek harus dilakukan, salah satunya adalah aspek kegempaan. Merujuk Perka BAPETEN Nomor 8 tahun 2013, evaluasi tapak perlu mengkaji kondisi geologi bawah permukaan. Tujuan dari penelitian ini adalah untuk mendapatkan informasi kondisi geologi bawah permukaan khususnya kedalaman batuan dasar di area tapak RDE. Metode yang digunakan dalam penelitian ini adalah microtremor array (MA). Hasil yang diperoleh menunjukkan bahwa tapak RDE memiliki batuan dasar berupa batuan dari Formasi Bojongmanik pada kedalaman 391 meter dari permukaan tanah.

Abstract

This study investigates the socio-cultural transformation of the Bakumpai community in Tumbang Samba, Central Kalimantan, driven by a major shift from river-based to land-based life. Traditionally reliant on riverine systems for livelihood, mobility, and identity, the community has undergone fundamental changes due to infrastructure development and the prohibition of illegal logging and mining. The objective of this research is to explore the dynamics of social change in this context, particularly how internal resilience and external pressures intersect to shape new social patterns. Employing a qualitative research design, the study used interviews, observations, and applied grounded theory through open coding procedures to generate conceptual categories. The findings reveal five key domains of transformation: spatial reconfiguration, occupational transition, technological integration, reorganization of social relations, and cultural reinterpretation. These shifts mark a profound redefinition of identity, economy, and interaction—from water-bound collectivism to land-based functional differentiation. The adoption of mobile technology, the relocation of settlements and trade centers, and the diversification of economic activities signify a move toward a digitally connected land society. In conclusion, the study offers a substantive theory of transition from river dependency to networked land adaptation, demonstrating how communities co-produce change by blending traditional values with modern modalities in response to policy, infrastructure, and ecological restructuring.
