KANDUNGAN NUTRISI KASGOT LARVA LALAT TENTARA HITAM (Hermetia illucensi) SEBAGAI PUPUK ORGANIK

[NUTRITIONAL CONTENT OF BLACK SOLDIER FLY LARVAE (Hermetia illucensi) FRASS AS ORGANIC FERTILIZER]. Nowadays, maggots or Black Soldier Fly (BSF)  larvae are widely used as organic waste decomposers. The use of maggot as a macro-organism waste decomposer is considered an innovation in processing waste. Maggot farming produces residue which is called Black Soldier Fly Larvae Frass (BSFF).  BSFF is called organic solid fertilizer and can optimize growth because it contains various nutrient flows needed for plants. Therefore, the objective of this study was to assess the nutritional content of BSF larvae reared in the waste of rice, fruits, vegetables, and their mixture.  Within this aim, it was conducted a laboratory experiment using four treatments of BSFF (the waste of rice, fruits, vegetables, and their mixture) research was conducted from March to June 2022 at the Experimental Garden and Integrated Laboratory of Trilogi University, Jakarta, with the Seameo Biotrop Laboratory, Tajur-Bogor, West Java. BSFF nutrient content was measured by the organic fertilizer test kit (PUPO) and standard laboratory procedure.  According to the result of the PUPO or laboratory test, it was found that BSFF from organic waste harvested two weeks has fulfilled the standard from Permentan 2019, especially on the treatment of giving waste of rice, vegetables, or fruits with pH criteria between 4-9, C organic more than 15%, ratio C/N less than 25, the total value NPK nutrient more than 2% and Fe was found to be less than 500 mg/kg.[NUTRITIONAL CONTENT OF BLACK SOLDIER FLY LARVAE (Hermetia illucensi) FRASS AS ORGANIC FERTILIZER].

‘BERTEHTUH’ ENGLISH: THE EXPERIENCE OF A TEMIAR GIRL IN ACQUIRING ENGLISH

Despite being a community that is often associated with the terms ‘illiterate’, ‘marginalised’ and ‘educationally disadvantaged’, certain indigenous students demonstrate positive developments in their second language proficiency (English). This issue creates a centre of attention as it can highlight suggestions to better the education of indigenous people in Malaysia. Having this in mind, a study was conducted in a remote indigenous school situated in the jungle of Banjaran Titiwangsa. In an attempt to investigate why the subject, an indigenous student of the Temiar tribe, is able to demonstrate better language proficiency compared to her classmates, a micro-ethnographic research that employed interviews as its instrument was conducted. Themes are generated through thematic analysis where this study concludes that the following three factors have hugely contributed to her success: (1) positive teacher (2) integrative-instrumental motivation and (3) supportive environment at home. This study also highlights conflict in culture between teachers and the indigenous tribe which is a result of the parenting styles, practiced by the indigenous parents, instead of their culture as claimed by the teacher. This paper brings to the fore the importance of teacher’s attitude and parenting awareness in empowering the process of learning English in this school. Keywords: English as the Second Language (ESL), indigenous people, individual differences, parenting styles, TemiarCite as: Mihat, W.

INVESTASI PASAR MODAL BERDASARKAN PRINSIP SYARIAH DALAM KAJIAN ISLAM

ABSTRAK   Pasar modal adalah tempat untuk melakukan aktivitas jual beli surat berharga atau perdagangan efek antara investor dan perusahaan emiten serta institusi lainnya. Pasar modal syariah mempunyai dua peran penting yakni; (1) sebagai sarana pendanaan bagi perusahaan untuk mengembangkan usahanya melaluli penerbitan efek berbasis syariah, (2) sebagai sarana investasi syariah bagi pelaku investasi. Penelitian ini mempunyai tujuan yaitu untuk mengetahui prinsip pasar modal yang berbasis Islam dalam rangka sebagai instrumen investasi produk di Indonesia. Metode penelitian yang digunakan yaitu metode deskriptif-analitis dengan pendekatan yuridis-normatif dimana penganalisisan dilakukan secara kualitatif. Hasil penelitian ini menunjukkan bahwa investasi di pasar modal syariah menjadi prioritas utama bagi masyarakat dalam melakukan investasi jangka panjang. Berlandaskan hukum Islam melakukan kegiatan pasar modal syariah diperbolehkan, pada dasarnya kegiatan pasar modal dimana kegiatan penyertaan modal dan jual beli efek itu merupakan segi muamalah, sehingga transaksi dalam kegiatan pasar modal diperbolehkan selagi tidak ada yang bertentangan dengan syariat Islam. Aktifitas muamalah yang dilarang yakni; spekulasi dan manipulasi yang didalamnya mengandung unsur Maghrib, Maysir, Gharar, Riba, Risywah dan Dzalim. Pasar modal di Indonesia di atur dengan Undang-Undang Nomor 8 Tahun 1995 (Undang- Undang Pasar Modal/UUPM). UU Pasar Modal tidak membedakan apakah  kegiatan pasar modal dilakukan menurut prinsip syariah atau tidak. Oleh karena itu, berdasarkan UU Pasar Modal, usaha pasar modal di Indonesia dapat dilakukan dengan prinsip syariah dan juga dapat dilakukan dengan prinsip akal sehat. Kata Kunci: Pasar Modal Syariah, Mekanisme Perdagangan, Investasi, Spekulasi     ABSTRACT   The capital market is a place for buying and selling securities or securities trading between investors and issuers and other institutions. The Islamic capital market has two important roles, namely; (1) as a means of funding for companies to develop their business through the issuance of sharia-based securities, (2) as a means of sharia investment for investment actors. This study has the aim of knowing the principles of the Islamic-based capital market as an instrument for investment products in Indonesia. The research method used is descriptive-analytical method with a juridical-normative approach where the analysis is carried out qualitatively. The results of this study indicate that investment in the Islamic capital market is a top priority for the community in making long-term investments. Based on Islamic law, carrying out Islamic capital market activities is allowed, basically capital market activities where the activities of capital participation and buying and selling of securities are muamalah aspects, so transactions in capital market activities are allowed as long as nothing is contrary to Islamic law. The prohibited muamalah activities are; speculation and manipulation which contains elements of Maghrib, Maysir, Gharar, Riba, Risywah and Dzalim. The capital market in Indonesia is regulated by Law Number 8 of 1995 (Capital Market Law/UUPM). The Capital Market Law does not distinguish whether capital market activities are carried out according to sharia principles or not. Therefore, based on the Capital Market Law, capital market business in Indonesia can be carried out with sharia principles and can also be carried out with the principle of common sense. Keywords: Islamic Capital Market, trading mechanism, Investment, Speculatio

Mapping of optimum placement of distributed generation in meshed power networks with appropriate technologies

Purpose: This study aims to propose a sensitivity-based methodology for the optimum accommodation of distributed generation (DG) units in meshed power networks with appropriate technologies. The effect of load variation is incorporated into the proposed methodology to identify the most trusted locations for DG placement. Design/methodology/approach: The effectiveness of minimizing active power losses is considered a key criterion. A priority list comprising both sensitivity indexes and realistic indicators is deduced to rank the optimum sites for the placement of DG units. A sorting index for distinguishing the suitable DG type(s) for each candidate location is organized. Three common DG types are considered in this work. The modified IEEE 30-bus meshed system is chosen to perform the proposed methodology. Findings: Results demonstrate that the obtained priority index can be used to achieve the best real loss minimization rates. Numerous load buses can be safely excluded as candidate locations using the proposed approach. Consequently, the methodology can minimize the computational process of diagnosing the optimum sites for DG accommodation. Originality/value: The findings determine that instead of installing many DG units at various locations with one DG type, a few certain load buses can be used to accommodate more than one DG type and significantly reduce losses
