Zanthoxylum acanthopodium, locally known as Andaliman, is exotic spices which grown in North Sumatera. Several investigation shown that the special taste and aroma comes from pericarp of Andaliman. However, the pericarp of Andaliman is easily degraded. The proper postharvest handling of Andaliman is necessary to preserve fresh Andaliman for long time. Previously, Andaliman has been preserved in packaging under room temperature storage. Further investigation of Andaliman preservation in packaging under low temperature storage would help reduces the postharvest losses. In this study, the physical changes of Andaliman in various packaging under low-temperature storage were observed. The results shown that within 2 days, the pericarp of Andaliman in paper packaging was shrunk, similarly found in control without packaging. Meanwhile, the pericarp of Andaliman in aluminum foil and PP plastic were found normal in day 3. This result indicated that in low-temperature, Andaliman in Aluminum foil was recommended for best postharvest handling.

Accreditation is a government assessment for a Higher Education. Based on the regulation of the minister of education and culture of the Republic of Indonesia number 87 of 2014 article 6, the validity period of the accreditation status and ranking of accredited study programs and tertiary institutions is 5 (five) years. During this time, the institution must prepare the documents used for accreditation. In 2019, the government has implemented changes to the standard accreditation assessment criteria of an institution, the evaluation of accreditation documents refers to several documents, one of them is Study Program Performance Sheet (LKPS) which is recapitulated in an excel. This research focuses on data integration at LKPS. In the LKPS excel data there is a relationship between the data with one another. One of the data that has a relationship is data related to lecturers with tridharma activities. Given that the application of this new rule began in 2019, this research focuses on designing the concept offline, namely Database integration made using Microsoft Access. LKPS analysis results have determined that there are 30 tables of which there are 22 integrated tables and 8 tables that do not have integration.

Pengendalian hama dan penyakit pertanian sering dilakukan secara kimia dengan menggunakan sprayer, salah satunya adalah sprayer semi-otomatis (knapsack sprayer). Sumber tenaga dan kendali pada knapsack sprayer berasal dari tenaga manusia. Operator harus memompa cairan yang terdapat pada tangki dan menyemprotkannya ke tanaman. Hal ini sering kali menyebabkan kelelahan otot di antara para pekerja. Oleh karena itu, dibutuhkan analisis terkait beban kerja petani saat pengaplikasian knapsack sprayer. Analisis beban kerja dilakukan dengan merekam denyut jantung petani laki-laki dan perempuan. Alat yang digunakan dalam pengukuran adalah Heart Rate Monitor (HRM). Pengukuran dilakukan dua kali, yaitu pengukuran saat kalibrasi dengan menggunakan metode step test dan pengukuran di lapang saat aktivitas penyemprotan. Tujuan dari penelitian ini adalah untuk menentukan beban kerja kualitatif (tingkat kejerihan) dan kuantitatif (konsumsi energi kerja). Hasil penelitian menunjukkan bahwa perempuan memiliki tingkat kejerihan yang lebih tinggi dibandingkan laki-laki, sedangkan konsumsi energi kerjanya tidak jauh berbeda. Dari hasil tersebut, dapat disimpulkan bahwa pengaplikasian knapsack sprayer di kecamatan Wedung lebih cocok dilakukan oleh laki-laki.

AbstractPlant Microbial Fuel Cell or known as P-MFC, is an emerging technology to produce electricity. P-MFC is projected as a possible solution in developing an alternative source of electricity that is highly available and sustainable. P-MFC is not releasing pollution during the running time. Hence, the only side product of this technology is water. The electricity could be harvested in situ, or directly on the reactor site location. P-MFC shows unique symbiosis between the plant and the microbe, which live around the plant roots area. Naturally, the microbe will eventually degrade the organic matter and convert it to electricity with the support of a particular P-MFC design. The P-MFC design for research purposes has already been various compare to the initial introduction. Besides, the plant type occupied has been diverse as well. This article reviews four main parts of P-MFC technology. Firstly, an explanation of fundamentals processes in P-MFC and its plant. Secondly, about the P-MFC design variations and its power output. Thirdly, about P-MFC power potential in Indonesia. And lastly, about the challenge of P-MFC application.Keywords: bioenergy, P-MFC, fuel cell, microbe, bioelectricityAbstrakSel Bahan Bakar Berbasis Mikroba-Tanaman atau lebih dikenal dengan Plant-Microbial Fuel Cell (P-MFC) adalah teknologi baru terbarukan untuk memproduksi energi berupa listik. P-MFC menjadi solusi potensial dalam pengembangan energi listrik alternatif yang mudah didapatkan dan ramah lingkungan. P-MFC tidak menimbulkan polusi saat digunakan karena hasil samping satu-satunya adalah air. Listrik yang dihasilkan dapat dipanen langsung dilokasi peletakkan reaktor P-MFC. Lebih lanjut, teknologi P-MFC memanfaatkan keberadaan mikroba yang hidup di sekitar area perakaran tanaman. Secara alamiah mikroba akan mendegradasi bahan organik dan kemudian mengubahnya menjadi listrik dengan dukungan desain P-MFC tertentu. Desain P-MFC sudah sangat berkembang sejak awal mula diperkenalkan. Selain itu, jenis tanaman yang digunakan juga semakin beragam. Pada tulisan ini, akan diulas empat hal penting mengenai PMFC. Pertama-tama, proses dasar pada teknologi P-MFC dan jenis tanaman P-MFC. Kedua mengenai variasi desain P-MFC dan efektifitasnya dalam menghasilkan listrik. Ketiga, tentang potensi P-MFC di Indonesia. Dan terakhir, mengenai tantangan utama dalam aplikasi P-MFC.Kata kunci: energi terbarukan, P-MFC, sel bahan bakar, mikroba, listrik-bio

Energi air menjadi Energi Baru dan Terbarukan (EBT) yang tengah digalakan saat ini. Dalam pemanfaatannya energi air dapat diaplikasikan menjadi suatu pembangkit listrik, salah satunya Pembangkit Listrik Tenaga Mikrohidro (PLTMH). Di Indonesia sendiri PLTMH telah banyak dikembangkan, terutama dalam mengatasi keterbatasan energi listrik di daerah terpencil. Namun, PLTMH masih belum berkembang secara optimal karena masih bertumpu pada aliran air dengan head tinggi, seperti air terjun. Hal ini tentunya menjadi perhatian khusus untuk memilih lokasi implementasi. Oleh karena itu dilakukan pengkajian dengan mempelajari bagian utama dari PLTMH, yakni dengan menggunakan turbin vortex. Berdasarkan julukannya turbin vortex memanfaatkan pusaran air dalam sistem kerjanya yang mampu diterapkan pada aliran air dengan head rendah, seperti aliran sungai. Dalam sistem kerjanya, turbin vortex harus memperhatikan jumlah sudu yang digunakan karena hal tersebut mempengaruhi kinerja turbin vortex dan keluarannya. Kajian teoritis ini dilakukan untuk mengetahui pengaruh jumlah sudu ditinjau dari keluaran PLTMH yang didasari dari sumber literatur terdahulu. Metode yang digunakan adalah metode deskriptif analitik dan kualitatif. Hasil dari kajian teoritis dapat diketahui semakin banyak jumlah sudu yang divariasikan maka akan semakin besar keluaran PLTMH, seperti nilai putaran turbin, nilai putaran generator, tegangan, arus, daya, torsi, dan efisiensi.
