Kelayakan Tekno-ekonomi Migrasi Teknologi Proses Produksi Gula Kristal Putih Dari Sulfitasi Ke Defekasi Remelt Karbonatasi

Sugar is a strategic commodity for Indonesia, such that the availibility and the price have been managed by the government. The national production of Indonesia sugar has not been enough to cover the consumption, such that the deficit must be imported. Indonesian sugar was produced by 61 factories, where 51 units are State-owned Company. Unfortunately, the quality of sugar produced by State – owned factory has been getting worse, such that some are not qualified to the Indonesian National Standards (SNI). One of the reasons is poor process technology adopted, which is mostly using sulfitation technology. The Government, therefore, encourages industry to migrate the process technology from sulfitationsystem to defecation remelt carbonatation (DRK) system. This study assesses the techno-economy feasibility of the migration. The results indicate that technology migration is technically feasible, but for the business, Government needs to give price incentive to the product. Furthermore, the study recommends that adoption of DRK technology should be prioritized to the factories with abundant stock of baggase

DETERMINING LANGUAGE TYPOLOGY BASED ON DIRECTED MOTION LEXICALIZATION PATTERNS AS A LANGUAGE DOCUMENTATION: A CASE STUDY ON JAVANESE

Every language has directed motion constructions, but the lexicalization pattern of the constructions may differ from one language to another. The similarities and differences of directed motion lexicalization patterns can be used as the basis for classifying languages typologically. This paper aims to discuss how language typology can be determined based on directed motion lexicalization patterns found in a language. In this study I use the data of Javanese to examine whether Javanese can be classified into Talmy’s (1975, 1985) typology of verb-framed or satellite framed languages. Some problems and implications of this language typology will be discussed to see whether there is interaction between directed motion lexicalization patterns and other syntactic structures. The data of Javanese show that Javanese has some verb framing and satellite framing characteristics, and so language typology is not exactly definite in the sense that there are some restrictions that need to be considered

ANALYTIC CAUSATIVES IN JAVANESE : A LEXICAL-FUNCTIONAL APPROACH

This paper is a study of analytic causatives in Javanese from a Lexical Functional Grammar (LFG) perspective. Analytic causative s are the type of causatives where there are separate predicates expressing the cause and the effect, that is, the causing notion is realized by a word separate from the word denoting the caused activity. The question addressed in this paper is whether analytic causative s form a mono - or bi - clausal structure. In addition, this paper aims to explain the mechanism of argument sharing between the verbs involved in analytic causatives. By using a negation marker and modals as the syntactic operators to test mono - or bi - clausa lity of analytic causatives, it was found that analytic causatives in Javanese are biclausal. These constructions have an X - COMP structure, in that the SUBJ of the second verb is controlled by the OBJ of the causative verb (N)gawe ̳make‘. The syntactic str uctures of analytic causatives are described within a constituent structure and a functional structure, two main components of LFG

MOTION-DIRECTION SERIAL VERB CONSTRUCTIONS IN JAVANESE: A LEXICAL-FUNCTIONAL APPROACH

Motion-direction serialization (MDS) is a type of verb serialization that involves motion and directional verbs. This type of verb serialization commonly occurs in serializing languages including Javanese. This paper aims to discuss the characteristics and syntactic structure of MDS in Javanese. The syntactic structure, which comprises constituent and functional structures, is presented by using the theory of lexical -functional grammar (LFG) By adopting the lexical conceptual structure, the writer presents a model of functional structure to explain the syntactic and semantic relation between the motion verb and the directional verb in MDS. The data used in this study were taken from the novel “Suparto Brata’s Omnibus: Kumpulan Roman” written by Suparto Brata (2007) In Addition, this paper also used spoken data from two Javanese native speakers of the Surakarta dialect. The result shows that MDS in Javanese shares the same SUBJ argument, aspect, and negation. This shows that MDS expresses a single event. The LFG analysis of MDS shows that the directional verb has an X-COMP function, which is semantically represented as DIRECTION in the functional structure. The use of lexical conceptual structure in lexical entry and functional structure can clearly show the semantic and syntactic relation of the verbs involved in MDS

Implementasi Program Bantuan Pangan Non Tunai (BPNT) di Kecamatan Kroya Kabupaten Cilacap

Bantuan Pangan Non Tunai adalah program bantuan pangan yang diberikan pemerintah mulai Tahun 2018 kepada keluarga penerima manfaat setiap bulannya dengan mekanisme akun elektronik yang digunakan hanya untuk membeli bahan makanan pokok di e-warung KUBE atau pedagang bahan pangan yang ditunjuk sebagai agen penyalur oleh Himbara. Program Bantuan Pangan Non Tunai (BPNT) untuk memberikan pilihan bagi keluarga penerima manfaat dalam mencukupi kebutuhan pokok sehari-hari. Di tingkat pusat, provinsi, kabupaten/kota dan kecamatan telah dibentuk tim koordinasi bansos pangan sebagai pelaksana program BPNT. Adanya mekanisme perubahan mekanisme penyaluran dengan menggunakan mekanisme transaksi elektronik ternyata tidak serta merta menjadikan program berjalan lancar tanpa permasalahan. Salah satu yang terjadi adalah di Kecamatan Kroya Kabupaten Cilacap. Beberapa kepala desa mengeluhkan terkait kurangnya koordinasi dalam pelaksanaan program antara pendamping, Himbara dengan pemerintah desa. Permasalahan yang lain yaitu adanya kegiatan pengumpulan kartu milik KPM yang akan mencairkan BPNT Tujuan penelitian ini adalah untuk mengetahui bagaimana pelaksanaan program BPNT di Kecamatan Kroya Kabupaten Cilacap serta untuk mengetahui bagaimana peran Tim Koordinasi Bansos Pangan Kecamatan kroya dalam pelaksanaan BPNT. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan teknik pengumpulan data melalui wawancara mendalam, observasi dan dokumentasi. Informan dipilih dengan metode purposive samplingdan Snowball Sampling. Keabsahan data diuji dengan teknik triangulasi yaitu dengan membandingkan dan mengecek kembali informasi yang diperoleh agar benar-benar dapat dipercaya. Data-data hasil penelitina dianalisis dengan metode analisis interaktif.Hasil penelitian ini menjelaskan bahwa pelaksanaan Program BPNT di Kecamatan Kroya berjalan baik sesuai dengan Pedoman Umum BPNT, tetapi belum optimal karena ada beberapa hal menyebabkan kurangnya kondusifitas dalam pelaksanaan program. Komunikasi dan koordinasi dalam pelaksanaan program berjalan cukup baik. Kurangnya kemampuan dan pemahaman dalam transaksi elektronik menyebabkan KPM menjadi tergantung kepada e-warung dalam mencairkan bantuan. Adanya data-data yang belum valid terkait penerima BPNT menjadi kendala yang menghambat kelancaran pelaksanaan distribusi BPNT. Keberadaan tim koordinasi bansos pangan Kecamatan Kroya menjadi sangat penting untuk menjaga iklim dan suasana kondusif dalam pelaksanaan program
